@@dirtrider88 Oh but we know it’s somewhat dangerous BECAUSE we understand it. Design specifications exist for a reason and in this case half of them went out the window 😂
@@dirtrider88 He literally spends a significant chunk of the video describing how dangerous his design is and how many changes would be necessary to offer it as a product. Did you even watch the video?
Hot video, Alec. Operating the release lever on the J1772 handle adds 330 Ω to the proximity pin to signal the load side to detach. You could operate your heater’s main relay signal on this signal to use those nice contactors you showed off.
Something tells me, that if he knew the resistor value and diode to get the car charger to turn on, he likely knew that, and as he basically stated, literally doesn’t care.
Wait.. The unspoken king of heat pumps installed a heater like this? I feel like we need to look into this. They might be held at gunpoint by some resistive heating lobbyists or something.
I'm guessing it's because a garage heater is used infrequently, so it makes sense to save 90% on purchase price even though operating costs will be higher
If his garage has a window like mine he could do window heat pump ac unit. Have ac in summer and heat in winter with window unit. Or cut hole in wall to mount it
I don't even get why you would heat your garage above 0°C - sure comfort and all of that but having the car ice free is enough comfort in my book. And even for just that a regular small big box store heater with a timer would be more than plenty.
i wish there were 4kw kettles honestly, you could almost do that with a 240V 20 AMP CIRCUIT. i want my tea FAST. there are even NEMA connectors for that too that are sometimes used for indoor a/cs
Now i really appreciate the level of design and engineering that goes into preventing people from hurting themselves, damaging electrical equipment, or burning their house down.

Same here, however I do not condone this solution even with the warings presented. Here in europe we have laws to prevent people from doing theese sketchy, DIY "solutions" to save a few bucks.

My wish is for food trucks and farmers market stalls to be able to plug in to curbside charging stations for cooking and miscellaneous power. Don't want to breathe that generator exhaust
@lordvlygar2963 It will be a while before food trucks themselves go electric, and a farmers market stall is not necessarily close to the operator's vehicle.
@@pfunk768 That may very well be true. Yet, anecdotally, I have seen food trucks made of EV pick-up trucks with a modular kitchen in the bed. So, it is possible and has been done, just hasn't caught on yet. And before you ask, it was a sausage and peppers sandwich stand/store/truck.
I remember someone who was north American and travelling in France sharing how, for places like that, there is permanently installed electric connections so that selers can simply plug their truck into the grid to power all the equipments required
@@ADMNtek You can already die messing with 120V if you’re stupid and unlucky. 240V increases the danger factor across the board even more. Better safe than sorry!
@@nolanthedude 120v might be safer from an electrical standpoint, but think of all the fires caused by someone plugging a space heater into an extension cord that couldn't handle the load. Combine that with the fact that most American houses are made from cardboard, and it's a recipe for disaster.
Fun Fact: there are industrial trailer mounted resistive heaters that are used as load banks for things like generator load testing. The one they use at my work is an 800 amp, three phase beast, and I like referring to it as the world's biggest toaster. :D

This channel is such a hidden gem. I’m sick as a dog and I’ve been watching Alec work with everything from humidifiers to kettles to the heater for his house and it’s been such a ride of information to consume while I rot. So glad I stumbled across your videos man, and as an Indiana native I relate to many many many of those Midwest tidbits.
I have a similar heater and it pulls ~21 amps at full load so all you need is 10gauge wire. The cord necessary would cost like $20-30 bucks and you don’t need that massively large cable the car uses.
@@rubiconnn for one, my tesla wall connector is hard wired, I don’t have an outlet. In theory this could be remedied Another reason is that a 50-amp plug is a pain to plug and unplug. The tesla NACS connector is very easy to plug and unplug as needed. Perhaps this would be a very niche product. But I’d be interested in it.
EV startup founder/CEO here, just wanted to say how impressed I am with this video. You described so many things about AC charging in a manner so clear that I'll be sharing it with people who need to understand how it all works better. I know engineers who could benefit from this! Thanks for making it, and doing such a clear and thorough job doing so!
Is this the Fēnix power start up from like 6 years ago that had one round of funding in 2018? I'm sorry, but you aren't a start-up. More like a no-start.
Having worked in engineering for quite a few years, I can confirm there are MANY, oh so many, engineers who could benefit from watching this channel. Also many startup founder/CEOs. (heh) Also that "digital" signals aren't really digital, but that's a whole different can of worms.
@@allaboutroofing2 Eh. Better to fail because you can't secure funding than succeed because the funding you do secure is from a nutjob who insists on putting himself in charge of stuff he knows nothing about, projecting a public image of being a genius inventor, using his earnings to buy out and immediately tank a major tech company, and [this space reserved for whatever horrible stuff he helps Trump do in the next four years].
In underground mines in US/Canada, the power cables for 3-phase power use a similar way of announcing power connection - they have a Pilot Wire, 3 phase wires, and ground wire. At the equipment (Load), there is a 5.6V Zener diode between Pilot and Ground, so that when connected there is a 5.6V potential from pilot to ground (instead of fancy communication schemes its just a roughly 20ma current loop which is happy when it sees 5.6V), but this ensures the piece of equipment has the same ground potential as the power source. This is referred to as "Ground Check" and ensures the equipment is always grounded for operator safety
Generally speaking, you make videos on topics I would otherwise never bother with. This is a prime example of one. Yet the way you narrate, your demeanor, dry humor and all of the other stuff just make me watch the entire thing and feel entertained the entire time. Well done sir
This is very clever. Also your note about politicians needing to add small cheap charging stations in accessible locations rather than large supercharger stations is incredibly true. They are thinking about building electric gas stations but in reality we need widely dispersed simple charging solutions in convenient locations. If every 4th parking meter had a small charger, that would probably be more than sufficient. If only more politicians watched your show
Why do we need politicians to provide charging solutions for us? Do you WANT to live in a Soviet state? I sure don't. Before I get blasted, please note that no communist nation has any real interest in protecting the environment and building nice electric cars. Those are features of capitalist economies. China is a weird case with their coal-plant-powered EVs.
Couple things, one, EV adoption is thankfully slow and even slower in rural areas. Theyre not popular enough to justify new policies like that. Adding slow chargers everywhere would be expensive and harder, compared to a few fast chargers off in the corner at gas stations, that get power anyway. I’d rather my taxes go towards something helpful for the environment. The one thing I can agree on is the 240v style receptacles in garages. I’m a car guy and being able to keep a garage unheated for most of the time and heat it up before I work on something or go out so the car doesn’t take so long to warm up would be nice. If homeowners want to fork up the money for a charger they can too.
It isn't politicians that do that sort of thing, it is companies that are looking to make a profit off of them. Why should my taxes pay for electricity for your EV when I am already paying for the roads you drive on?
@@harpintn Your taxes pay for a lot of stuff not directly for you. That's why they are "taxes" and not "you shopping". Anyway the answer is to improve society and prepare for the future.
@@obi1998 Never the less, as an EV owner you are not paying gas taxes, yet your vehicle is doing more damage to the roads than ICE vehicles. One of the foundations of our tax system is that is should be fair. ICE owners paying the way for EV's is not fair at all.
6:47 THANK YOU! As an EV owner living in a flat in a pedestrianized area my primary mode of charging is AC charging at 22 kW using public infrastructure close to my flat. And that just works. But it seems everyone is increasingly stubborn in focussing on DC gigawatt charging 0-80% in 2 minutes. I have a cheap, old, and crappy EV. If my city hadn't built 22kW AC chargers I couldn't own an EV. But the entire country stopped building them, the prices are going nuts and 22 kW AC charging is rarely even an option in new EVs. People that have to park their cars on the streets and don't have money for a large battery need charging infrastructure, too. But it'd be good for everyone, as not having to stop for charging will always be faster than the fastest charger. A few days ago I went to charge my car to visit relatives and almost all of the chargers were in use by cars with huge batteries and crazy charging speeds but they all used destination charging instead.

Often tripping up over the same grievances with products, and using similar expressions and phrases. One of my top 5 subbed channels, hands down.
This reminds me of how in the early days of electricity in the home, a lot of devices came with an _edison screw_ connector, because, you know, the _lights_ in a house were electrified first, before we designed wall outlets and before they were common. If you got _really_ lucky, it might even be a nice enough connector to allow you to still plug in your light! So you could still SEE!
In the UK sockets were initally uncommon and some providers would charge less for electricity used for lighting, hence lamp adaptors being common. Naturally they got abused and were very dangerous but standards didn't really exist sonit was a bit of a free for all.
I love how there is a random LaserDisc™ laying on your tool bench in your garage. that re-organization project is much more desperate than you made it sound at the beginning! I hope your things find a wonderful and good and right home.
I feel like some people in the comments are missing the point of this a little. I've seen a few Europeans and Australians pointing out they already have 240 volt AC, which...yeah we know, and a couple people pointing out the existing 240 volt plugs you could attach to the heater. Both of those things are addressed in the video. The point is that there exists an extremely easy to use way to power high current 240 volt devices but it's currently severely underutilized. Honestly Alec, this is a really incredible idea and the fact that you made it real is super cool!
As an Australian myself I'm not convinced those commenters had even watched the start of the video properly, our 230V connections can handle more power than a NEMA 15 can but not anywhere near 7.5kW, and most of the European comments are mentioning 3 phase connections which is pretty much the entire point of this connection - a multiphase high current outlet.
For European circuits the same principle applies; you could get 3.6 kW out of a normal outlet, but an electric car outlet can provide 19.2 kW or even 38.4 kW depending on how it's hooked up. Although I've never had significant problems plugging or unplugging anything from a CEE Red outlet.
I am a huge proponent of human-written captions, so I’m super happy to see that you still write yours yourself. However, the line lengths at 9:04 are a little unruly and hard to read. The software I used in the past for captioning (Subtitle Edit, which is… fine) follows the recommended line length of around 40 characters. It’s way more readable while allowing for natural breaks in the text.
I've done the same for a large battery product (22 kW available in EU), analog resistor + diode technique was way simpler than expected! Some cheap charger even accept the resistor only. It's also possible to add another precise resistor + a button to make the equivalent of the "cable release" button for EVSE that lock the cable. This way it's possible to trick EVSE on the road. Amazing to see a DIY video from you :)
I love Alec's specifically inserted and very unmissable Do Not Try This At Home legal diaclaimer, spoken in a tone and with a distinct pause afterwards which loudly said "Look, if you're going to try this at home I can't stop you, and I actually think this is a pretty good idea or else I wouldn't have built it. But you really need to be very aware of the risks to life and property that you're taking on here, please do not injure your family and/or burn down your house and then say that I told you to do this." One can't be too careful these days. Great idea mate! (using the car charger to power other high-load stuff I mean). Funnily enough, I have a similar but opposite problem; I've decided it's really about time to clean out the very poorly insulated sunroom (junk storage room) at the height of Aussie summer... an AC car charger would be great to run a portable air-conditioner (heat pump) if only they weren't so horribly inefficient due to the open-loop design. :(
The dual hose portable models are actually fairly reasonable efficiency wise since they mitigate the open loop issue (condenser air is both pulled from and then returned to the outdoors). Not as good as a window or permanently installed unit but not nearly the energy guzzlers they used to be, especially if you get one with variable speed compressor.
I came to the comments just to acknowledge my favorite malaphore! “Burn that bridge when we get to it” a blending of two idioms “Cross that bridge when we get to it” and “Burning your bridges”. I applaud your use of figurative language 🎉
I'm fond of "Don't count your chickens before they come home to roost." It works well for warning people not to be overconfident that things won't go horribly wrong.
This is hilarious. I used to repair very large electric boats where we used all of these tricks to get them to work. One thing we did was use intentionally small wires that would burn out and kill the power before the 12v batteries (in series) would blow up or the motor would overheat. "It's a 72hp motor but you're using a tiny red wire?" Yes. It's intentional. Granted, this was definitely not the correct solution, but it was one that safely worked haha.
Theoretically, it should be pretty easy to make this thing respect the charger's current limit. Basically any microcontroller should be able to work with the J1772 capacity communication and respect the connector's disconnect switch if programmed correctly. Then, a simple relay could be used to interrupt the control cirquit for the heater's contactor accordingly. So with enough dedication, this could easily be made safe.
It would even make the unplug-arc go away, would provide a way to delay the enablement of the power for a second while being plugged in, and could also drive a solid state relay to enable/disable the load without arcs entirely by using zero-cross-detection. And the last one could even allow PWM to adjust precisely to the allowed current.
Probably not, as with either low frequency duty cycle control or a chopper dimmer, peak power is basically unchanged. Heat generated in the conductors is proportional to the square of the current (which is proportional to the delivered power)
If you purpose modded a multi-coil heater to do this, contactors could rewire the coils (series versus parallel) to obey that limit. I did steal this idea from Subaru heat seats from before they went through the ecu.
I think the other point of concern is the connector temperature. Most EVs will monitor the connection point thermals and pause or derate in the event of excessive heat/resistance in the connector. If there is buildup on the connector pins or the plug angle is not flush there can be a lot of heat generated through those pins.
Yeah I was thinking that something like a 250V, 48A Power MOSFET would be better. There are plenty of products out there more than capable of doing this they are used in all sorts of industrial control systems etc like the solid state inverters of multi-speed industrial motors. Hell electric locomotives use this technology and they can be switching 25KV 5KA supplies.
This is so scary relevant that I feel like it was made for me. I've been watching this channel on and off for a long time now, but only a few days ago I was looking at an almost identical heater for my workshop. I also was having issues with how to properly power it. I was going to run a new set of 10/3 to power it, myself. But this still feels like a video tailor made for my current situation.
I have been thinking about doing this exact project and some others for quite some time. An Arduino and a few extra components are more than up to the task of interpreting the J1772 or NACS signals. The biggest place I think this kind of usage could be useful is for food trucks. Right now, food trucks run very noisy expensive and polluting generators for power. If a food truck could use an existing EV charger for power, food trucks would be much more enjoyable and environmentally friendly. In Washington DC right by the mall, there are usually about 20 or more food trucks in a long row, all running really smelly gasoline and diesel generators. A row of EV chargers could solve this and also be used for car charging. The one fly in the ointment for this solution is that the J1772 plug only has L1, L2, and safety ground; there is no neutral. Some loads like deep fryers or griddles may natively use 240VAC, however many things are going to want 120VAC. A simple solution to this problem would be to use a 1:1 transformer with a center tapped secondary. The center tap of the secondary could be bonded to the safety ground in the food truck’s electrical panel. Then the derived neutral from the transformer could be used to supply 120VAC loads. A microcontroller could be used to monitor the applied loads, provide a visual indication of the available power, and open a contactor if the loads exceed the available power. Other uses for EV charger power at home I have thought of include things like log splitters, pressure washers, and snowblowers which are only used occasionally and frequently get ruined carburetors from bad gas. These kinds of equipment need more power than a standard 120V outlet can provide, so having access to the kind of power an EV charger can supply would be a game changer Another thought I have had is to use an EV charger to power an electric grill. A 120V outlet is really marginal for powering a grill in the same way that propane does. Anybody else interested in things like this ? I’m an electrical engineer with a lot of design experience. Fabulous video as always by the way !!!
Along with your food truck idea, you could even go as far as using DC fast chargers for power. Take the 150 kW of DC power, run it through an inverter, then have a center tapped transformer on the output. Use the same signaling for current to match the load of the trucks. This probably isn't super practical because of the size of equipment involved, but it's easier than having a dedicated service for them. You could even have a 208Y transformer if you wanted to offer 3 phase. As far as the garage, as long as your service could handle it, there are common 80 amp chargers that really open the door to high powered applications. Similar to the industrial environment, where 480V drops are common around plants, for anything like welding, portable offices, and temp panels. At home, there's not much that 19.2 kWs won't be able to handle. If I wouldn't have been allergic to the classroom environment, I would have loved to be an electrical engineer.
It would be cool to see a food truck-like thing made out of say a Rivian van one day. So much power on board. And it would be wise for new food truck areas to be built with 240V power hookups for all spots.
After some research, it seems like adding the product features Alec requested with an Arduino or microcontroller might be a bit trickier than it looks due to the chicken and egg problem of interpreting the Control Pilot signal BEFORE calling for power from the charger. Or, if you default to power on, then there is a problem knowing the release button is still being pushed after the power has been cutoff. @TechnologyConnections, If you are up for it, I would love to try and build a POC control board and send it your way for testing.
@@jamesgartrell4462 You use the passive components to enable AC, which then powers your logic circuit. Then use the pilot signal to control the heater's contactor.
@jamesgartrell4462 what about including a small rechargable 5v battery to carry the Arduino while waiting for the control pilot? Then once all the checks are done for connection, signal for mains power, close the contactor, and then recharge the cells and run off of a control transformer for the Arduino
27:17 That is why I love the Electrical Connectors we use in Germany: - CEE 7/3 (Type E Socket aka Schuko) and CEE 7/7 (Type E & F Plug) for up to 16A (for continues loads it is only recommended to use 10 - 13 A max, e.g. Car charging) - IEC 60309 (aka "CEE System") with ratings up to 125A for continues loads (16 A, 32 A, 63 A & 125 A) > 230 V, 1 Phase (L, N & PE) > 230 V / 400 V, 3 Phase (L1, L2, L3, N & PE) - Type 2 for Car charging - CCS 2 for Car fast charging

@@lajya01If you mean an electric heater _connected to the mains power grid_ (as opposed to powered by the car via an inverter), it'll almost certainly be cheaper to use an electric heater. Idling an ICE vehicle uses an amount of fuel, per hour, approximately equal to 0.6× the engine displacement. For my 1.3 litre (1300 cc) hatchback that's 1.3×0.6 = 0.78 litres per hour, which is around £1.05/hour at current UK prices for unleaded petrol. An electric heater would likely need to be absurdly overpowered for car-heating purposes to cost anywhere close to £1/hour at typical UK electricity prices. I'd imagine that even a 1 kW heater would be too much to run continuously in a car. Though obviously this depends on the car's thermal insulation and the outside temperature.
I don't normally leave comments but I have been a fan for so long and I recent watched some of your super early stuff. I absolutely love your old intro and the jingle. You have come a long way and you have taught me many things that I have always wondered about. Please keep up the good work! You are killing it.
24:55 - Fun fact on early Tesla's. The main 400V battery pack contactors wore out very quickly due to the arcing damage from opening and closing all the time under different voltages/loads. Tesla fixed this by having voltage detection circuits on both sides of the contactor. When the car wanted the contactor to close, it matches the voltage on both sides of the contactor before closing. Leading to little, if any arcing. After the contactor is closed, it's then able to push through the massive amperage needed.
Your work has been there for me for years! I watch your videos and it makes me feel happy to be alive! There are so many fascinating stories and people design such complicated machines. We used to measure things with our hands, and now we can run lightning into our homes. Your videos remind me of this.

I've searched and searched for how those connectors and charging work and found nothing. The searchable web really is dead. Your explanation is the best I've ever heard. TY for that.
Only a minute in but that heater is a great picture of the future for me. There are a lot of occasional use “shop tools” that would benefit from this. The heater is a perfect example because it benefits from the extra pixies but even table saws or compressors would benefit. Things you’d use in the garage to work “where the car normally is”. Hopefully that comes along with ubiquitous pixie powered cars.
Welder! My buddy has a welder that can plug into 120v 15A or 240v ?Amp. Either way, it’s an intermittent use device that could be powered with an electric car charger outlet! I’ve tried to figure the cost of running a dedicated 240v outlet for JUST a welder for him, but it costs too much for his limited use.
@ The “problem” is that there’s no profit motive. “Big Welder” doesn’t make money off of intermittent welders, they make money off of people who make money welding. The actual product that can come to market here (at least in 2024) is an “interposer” that handles the “pretend to be a car” part and gives the user a “safe” outlet.
I've literally been looking for a way to power an EVSE and a 7.5kW garage heater with a single 50a circuit for months now, and you've given me the exact solution I need, the perfect Christmas gift!

@@leecasey3022 Right? Even a mobile home needs 100A at the minimum and that's assuming it's an ancient single wide model. I call bullshit on that. The solar power is additive at best.

I may have seen these on your channel but there's smart switches that you can plug two 240v 30a devices into with a NEMA plug (there's a couple plug types available) and they'll power a secondary load if nothing is on or the primary load and turn off the secondary if both are on. I bought one and tried it with a 5000w heater and my dryer on it (it worked) but I ended up returning it in favor of hard-wiring the heater because I'm using it to keep my washer from freezing. I generally keep it set around 50f but crank it up when I'm working out there. When I first got it I cranked it up to max on a 5F day and it got my garage to 90F, lol.
The other reason that you do not want to cycle plugging in different appliances into those NEMA plugs is because they are generally manufactured cheaply because they usually get an oven or dryer plugged in to them and then that's it. Cycling a cheap plug will eventually lead to a high voltage arc that is very likely to cause a fire.
A company I know uses heaters on an adapters like that to get a controlled load for the charging stations they make. It was cheaper than a suitable quantity of power resistors. (Which would use the same adapter but would look more... technical I guess.)
I’ve heard of some of the larger “solar generators” having a J1772 input. Since they’re approaching multiple kWh now, a regular outlet is going to take a while to charge them.
In Norway, and probably most of europe, we have both 230V and 400V plugs that can handle loads up to 63 amps at three phases. They look pretty similar to your charging cable, but are color coded with blue for 230V and red for 400V. These have been standard for decades, and are pretty much common in both industry and some home garages where workshop tools are used.
American homes only have 220-240 going in, then splitting 110/120 up or down for the standard outlets. There's around 480 coming off the street, but I think you have to have a commercial license in most states to run a line for it, which allows service stations and other things to transform it personally outside their building.
Yup. To get order of magnitude energy reduction you need to abolish R1 zoning (to allow multiple dwelling units to share walls) and get most people on mass transit (economies of scale).
And then you realise that, with over 9kWh in a litre of petrol, that ICE vehicles require 5 times or more of the energy to move the same person the same distance. Typical ICE vehicle efficiency is below 20% in the real world, 80% of the energy in the fuel is simply wasted as heat, noise and vibration. Think about that...
23:34 To my EU industrial electrician eyes that "nice" contactor looks like every other contactor I've pretty much ever seen installed anywhere. Even most home electrics have a similar ones for sauna stoves or boilers etc.
@@AMalas I think you've got that backwards, what they're saying is that the contactor that Alec sees as relatively high end by US standards would be an assumed standard in the EU, implying the availability of lower grade designs in the US than what's allowed in the EU. Similar to how the EU tends to use Wago connectors for wiring where the US typically uses wire nuts.
Same here in Paraguay, South America. At home I put 3 phase ("mini") contactors to everything, my ovens, water heater, steam iron, etc, really because a like the "clunk" sound.. Generally the contactors controlled by wifi switches. So everything is controlled the same way no matter the load is. Greetings from Asunción.
Do you think during the winter months you will generally just keep the charging station plug parked up there in the shop heater? Or do you tend to hang it back on the standard cradle when not in use? When the shop heater is off, is the circuit completely off with no vampire load?
There's the glowing light on the front, but I doubt there's any notable vampire load - wasting power requires components, and that thing doesn't have many to do the wasting.
Probably not - I expect this will get used pretty rarely. And as far as vampire loads, the heater only has that neon indicator which is negligible but the charging station would hold its contactor in continuously if I left it plugged in, and that probably pulls a watt or so.
Talking about plugs, remember the video where you explore the holes used for indexing during manufacturing of the regular plugs? You probably know this already by now but in Japan they use those holes as part of a locking safety system specially for outdoor plugs (like varanda placed washing machines). You just stick them in and twist, then a mechanism inside the wall outlet will lock the pins. You CAN use them without locking and you can install them indoors too but I have only seen them outdoors on apartments and on industrial settings. You could check if you have any patreons that live in Japan that would be willing to mail them to you so you could do a video on them if you interested.
I completely agree. For most use cases, a single "charger" at home is all that is needed. We have 3 EVs/drivers on a single 20a/220v else on the driveway, and 99% of the time, it is all we need. That 1% is when I plug in at work using the portable box in the fridge or hit a DC fast charger on the way out of town.
To be fair, the 14-50 is a pain to plug/unplug as described in the video. Personally, I did something similar but I used a California style twist lock connector instead of the j1772
@@KristinaBaker-ql5hi sometimes im not sure if people actually watch the entire video or not, would be interesting to see youtube timestamp when a comment was posted for xmas comment 3:10 was addressed and reasoning is at 3:44 for kristina 14:18 all of this isnt even the point of the video anyway
@ my point was never to unplug and re-plug the heater in my point was that you can just install a second plug sometimes I wonder if people even read the comment before they post mindless banter in reply
@@KristinaBaker-ql5hi It's explained in the video at 14:18 why installing a second plug would be impractical. (To repeat from the video: because adding a second circuit for a second plug would nearly fill up the electrical box, and probably wouldn't be approved by an electrician without an electrical service upgrade.) Edit: I guess the part that's not obvious is that North American electrical codes do not allow you to have multiple outlets of this type on a single circuit.
I have an electric bike. As the chargers for these bikes have a normal household connection, if you run out of power on the road you either have to pedal yourself or drive to a charging station for e-bikes. But there are also a few manufacturers who have built adapters from electric car charging stations to household sockets. They also have to pretend that the charging station is a car, but it works. It works not only with bicycles but with all electrical devices that you might need on the road.
If, at some point, somebody manages to produce an e-bike battery that could recharge itself in 5-10 minutes, being able to use car charging infrastructure to extend your range would be awesome! (Hopefully, the charging adapter required to do this would not be too bulky to carry on a bike).
Why not just plug that into the socket in the wall? Wtf am I missing here, is there some US regulation that forbids using that socket for anything else?
@@mister_milkman as mentioned in the video, there’s nothing *wrong* with unplugging the car charger to plug in a welder. However the plug is not designed for frequent plugging and unplugging. The 1772 connector at the other end is designed for it. So if a welder can be modified to *safely* use the 1772 connector for power input, it would be a good idea.
@@stazeII that’s why I said it would be a good idea if it can be done safely. I’m not certain whether it can be done safely or not as I don’t have any experience with welding.
Hey, thanks for stating out the Celsius conversion at 16:24. I know it's a chore and commenters can give you a hard time when you don't. It's a show of kindness on your side towards us international viewers and it doesn't go unappreciated with me ❤️

Cool to see the Ioniq5 still around, didn't know how long you'd have it. Another update would be nice! You're one of the best subtle advocates out there for EVs (and prioritizing Level 2 charging), and I further appreciate the subtlety of mentioning car dependency in an appropriate, negative context.
Here in the UK we have the option to use "commando" plugs. The single phase varients have three separate sizes which are incompatible with each other but our biggest can handle 63a at 230v for a whopping 14.5kW of power. Thats more than most houses consume at full load. You could litterally plug a house into another supply. We also have 3-phase plugs that can handle crazy power but they are used in industrial and commercial applications.
As a European, watching you talk about the different nema plugs and electrical systems in North America always kinda scares me. Over here, we have basically 5 types of plugs, including two very rarely used ones and also two three phase connectors (16A and 32A). Our the charging plug is very similar to yours, but it has a electronic locking mechanism so the car and/or the charging station can prevent disconnection under load. You would have to switch off the resistor at CP (or rather change the resistance) to be able to unplug the cable.
Almost all of those are very uncommon. In residential settings, we just see 5-15 for 120v (what the rest of the world thinks we only have LOL!), and 14-30 for electric dryers and 14-50 for electric ranges. All those other types are either legacy/now out-of-code (the 1-, 2- and 10- series) or for very special-purpose commercial or industrial purposes (especially the 3-phase versions). And then, usually stationary 240V or 277V 3phase appliances or machines are often just hard-wired. 😉 _edit:_ couple of dumb typos
@@youdontknowme5969 Ok, that checks out. Still I probably won't need to mention the dangerous flaws that the 5-15 has (as well as the 14-30 shown in the video) because you surely have seen Alec's video about that as well 😉 I have found out though, that there are in fact "L" versions of the nema plugs. How common are those?
I mean Europe has it's fair share of obsolete and weird plug standards. I think the difference is that it was much easier to get away from them because of the universal 3 phase 230/400V supply both to most residential homes and to commercial buildings. There just never was a big need for a plug that supplies more than 16A on a single phase at 230V. Anything more power hungry can just be connected with an appropriate CEE plug or is hardwired. There just was less incentive to add plug standards.
well huh, more than heaters, welders, lathes, mills, planers, jointers etc. There are a lot of tools that a home shop can use that currently require dedicated wiring, but realistically, a lot of people only use one tool at a time that would require the 240. So, I see a bodged together multi-outlet adaptor that goes on the end of the car charger cable and is able to take the plug from various machines. This, is going to get interesting.
He mentions the government investing/focusing on home charging. The scary part of people charging at home is that they are unlikely to inspect and maintain it, especially if they have little or no money. This can lead to fires that could burn down entire apartment buildings, especially if people try to do a project like this heater. I hope we will all have electric cars and home charging, but when we do, it will become a need instead of a want, and the electric companies and government wll then raise the fees as high as they can, and that is the sad part. On costs, it is probably better for people with electric cars as long as electric is not the mainstream.
@@itoibo4208 i’m also terrified of gas lines getting installed in homes because the chances of those getting maintained constantly are slim. If those leak they could cause a fire or even explosion or just suffocate people. terrifying!!
21:00 I wouldn't use relays in this kind of circuit - high power relays with high current ratings are expensive and should be avoided. The easier way would be to have the heater refuse to turn on if the configuration is set to the wrong amount of power. This could be achieved with a 3 way switch and a small sensing circuit, avoiding the extra cost and providing more safety.
EV charger style connectors designed for repeated insertion and removal without wearing out the connector honestly should be more common. Mostly unrelated to the subject of the video, but I could see a J1772 or similar connector becoming the standard hookup for RVs/campers at powered campsites.
You sure have connected some technologies in this one Alec.

"do not try this at home"
Damn it.. my dream of a hot tub with a J1772 socket on it are dashed yet again
No no.. The do not try this at home, means at your home. He never said anything about your neighbors house.
But a hot tub is not a space heater, so not "this". I guess you're good to go with your project.
If the hot tub is outdoor, is it actually at home?
Tech Man Guy said that but he cannot stop you. Don't let your dreams stay dreams
Important difference: He said "do not try" not "do not do", as he already tried it, you can now simply do it.
Hot video, Alec. Operating the release lever on the J1772 handle adds 330 Ω to the proximity pin to signal the load side to detach. You could operate your heater’s main relay signal on this signal to use those nice contactors you showed off.
Something tells me, that if he knew the resistor value and diode to get the car charger to turn on, he likely knew that, and as he basically stated, literally doesn’t care.
I don’t know what any of the nerdy jargon in these two comments means but I love it.
Wait.. The unspoken king of heat pumps installed a heater like this? I feel like we need to look into this. They might be held at gunpoint by some resistive heating lobbyists or something.
I'm guessing it's because a garage heater is used infrequently, so it makes sense to save 90% on purchase price even though operating costs will be higher
I think he hasn't found a powerful enough pump
If his garage has a window like mine he could do window heat pump ac unit. Have ac in summer and heat in winter with window unit. Or cut hole in wall to mount it
I'm guessing that a heat pump wouldn't have any hope of achieving the same *_speed_* of heating.
I don't even get why you would heat your garage above 0°C - sure comfort and all of that but having the car ice free is enough comfort in my book. And even for just that a regular small big box store heater with a timer would be more than plenty.

Fun Fact: there are industrial trailer mounted resistive heaters that are used as load banks for things like generator load testing. The one they use at my work is an 800 amp, three phase beast, and I like referring to it as the world's biggest toaster. :D
I used to work at the factory. One of those things disappeared without a trace during a 45 minutes midday break. It didn't even have wheels.

@@Agnemons but its also only really a dollar to heat up the garage in an hour, and then greatly decreases

In underground mines in US/Canada, the power cables for 3-phase power use a similar way of announcing power connection - they have a Pilot Wire, 3 phase wires, and ground wire. At the equipment (Load), there is a 5.6V Zener diode between Pilot and Ground, so that when connected there is a 5.6V potential from pilot to ground (instead of fancy communication schemes its just a roughly 20ma current loop which is happy when it sees 5.6V), but this ensures the piece of equipment has the same ground potential as the power source. This is referred to as "Ground Check" and ensures the equipment is always grounded for operator safety
Generally speaking, you make videos on topics I would otherwise never bother with. This is a prime example of one. Yet the way you narrate, your demeanor, dry humor and all of the other stuff just make me watch the entire thing and feel entertained the entire time. Well done sir
This is very clever. Also your note about politicians needing to add small cheap charging stations in accessible locations rather than large supercharger stations is incredibly true. They are thinking about building electric gas stations but in reality we need widely dispersed simple charging solutions in convenient locations. If every 4th parking meter had a small charger, that would probably be more than sufficient. If only more politicians watched your show
Why do we need politicians to provide charging solutions for us? Do you WANT to live in a Soviet state? I sure don't.
Before I get blasted, please note that no communist nation has any real interest in protecting the environment and building nice electric cars. Those are features of capitalist economies. China is a weird case with their coal-plant-powered EVs.
Couple things, one, EV adoption is thankfully slow and even slower in rural areas. Theyre not popular enough to justify new policies like that. Adding slow chargers everywhere would be expensive and harder, compared to a few fast chargers off in the corner at gas stations, that get power anyway. I’d rather my taxes go towards something helpful for the environment.
The one thing I can agree on is the 240v style receptacles in garages. I’m a car guy and being able to keep a garage unheated for most of the time and heat it up before I work on something or go out so the car doesn’t take so long to warm up would be nice. If homeowners want to fork up the money for a charger they can too.

6:47 THANK YOU! As an EV owner living in a flat in a pedestrianized area my primary mode of charging is AC charging at 22 kW using public infrastructure close to my flat. And that just works. But it seems everyone is increasingly stubborn in focussing on DC gigawatt charging 0-80% in 2 minutes. I have a cheap, old, and crappy EV. If my city hadn't built 22kW AC chargers I couldn't own an EV. But the entire country stopped building them, the prices are going nuts and 22 kW AC charging is rarely even an option in new EVs. People that have to park their cars on the streets and don't have money for a large battery need charging infrastructure, too. But it'd be good for everyone, as not having to stop for charging will always be faster than the fastest charger. A few days ago I went to charge my car to visit relatives and almost all of the chargers were in use by cars with huge batteries and crazy charging speeds but they all used destination charging instead.

If you got _really_ lucky, it might even be a nice enough connector to allow you to still plug in your light! So you could still SEE!

@@dvpierce248 I have a few of those to turn a lamp into an extension cord (which also provides light). lol

I feel like some people in the comments are missing the point of this a little. I've seen a few Europeans and Australians pointing out they already have 240 volt AC, which...yeah we know, and a couple people pointing out the existing 240 volt plugs you could attach to the heater. Both of those things are addressed in the video. The point is that there exists an extremely easy to use way to power high current 240 volt devices but it's currently severely underutilized. Honestly Alec, this is a really incredible idea and the fact that you made it real is super cool!
As an Australian myself I'm not convinced those commenters had even watched the start of the video properly, our 230V connections can handle more power than a NEMA 15 can but not anywhere near 7.5kW, and most of the European comments are mentioning 3 phase connections which is pretty much the entire point of this connection - a multiphase high current outlet.
@@bosstowndynamics5488 J1772 is single phase. It is the EU variant, IEC 62196-2, SAE J3068, that has up to 3 phases.
In the EU the single-phase voltage has been standardised to 230vac.
For European circuits the same principle applies; you could get 3.6 kW out of a normal outlet, but an electric car outlet can provide 19.2 kW or even 38.4 kW depending on how it's hooked up.

I've done the same for a large battery product (22 kW available in EU), analog resistor + diode technique was way simpler than expected! Some cheap charger even accept the resistor only.
It's also possible to add another precise resistor + a button to make the equivalent of the "cable release" button for EVSE that lock the cable. This way it's possible to trick EVSE on the road.

But you really need to be very aware of the risks to life and property that you're taking on here, please do not injure your family and/or burn down your house and then say that I told you to do this."
One can't be too careful these days. Great idea mate! (using the car charger to power other high-load stuff I mean). Funnily enough, I have a similar but opposite problem; I've decided it's really about time to clean out the very poorly insulated sunroom (junk storage room) at the height of Aussie summer... an AC car charger would be great to run a portable air-conditioner (heat pump) if only they weren't so horribly inefficient due to the open-loop design. :(
The dual hose portable models are actually fairly reasonable efficiency wise since they mitigate the open loop issue (condenser air is both pulled from and then returned to the outdoors). Not as good as a window or permanently installed unit but not nearly the energy guzzlers they used to be, especially if you get one with variable speed compressor.

I'm fond of "Don't count your chickens before they come home to roost." It works well for warning people not to be overconfident that things won't go horribly wrong.
You would love the AvE channel then.
You are incredibly talented, and your videos provide detailed and well-organized information.
This is hilarious. I used to repair very large electric boats where we used all of these tricks to get them to work. One thing we did was use intentionally small wires that would burn out and kill the power before the 12v batteries (in series) would blow up or the motor would overheat.
"It's a 72hp motor but you're using a tiny red wire?" Yes. It's intentional.
Granted, this was definitely not the correct solution, but it was one that safely worked haha.
I guess anything can be a fuse if it's expendable and your threshold for "pulling too much power" is high enough.
Theoretically, it should be pretty easy to make this thing respect the charger's current limit.
Basically any microcontroller should be able to work with the J1772 capacity communication and respect the connector's disconnect switch if programmed correctly. Then, a simple relay could be used to interrupt the control cirquit for the heater's contactor accordingly. So with enough dedication, this could easily be made safe.
It would even make the unplug-arc go away, would provide a way to delay the enablement of the power for a second while being plugged in, and could also drive a solid state relay to enable/disable the load without arcs entirely by using zero-cross-detection. And the last one could even allow PWM to adjust precisely to the allowed current.
Probably not, as with either low frequency duty cycle control or a chopper dimmer, peak power is basically unchanged. Heat generated in the conductors is proportional to the square of the current (which is proportional to the delivered power)
If you purpose modded a multi-coil heater to do this, contactors could rewire the coils (series versus parallel) to obey that limit.
I did steal this idea from Subaru heat seats from before they went through the ecu.
I think the other point of concern is the connector temperature. Most EVs will monitor the connection point thermals and pause or derate in the event of excessive heat/resistance in the connector. If there is buildup on the connector pins or the plug angle is not flush there can be a lot of heat generated through those pins.
Yeah I was thinking that something like a 250V, 48A Power MOSFET would be better. There are plenty of products out there more than capable of doing this they are used in all sorts of industrial control systems etc like the solid state inverters of multi-speed industrial motors. Hell electric locomotives use this technology and they can be switching 25KV 5KA supplies.
This is so scary relevant that I feel like it was made for me. I've been watching this channel on and off for a long time now, but only a few days ago I was looking at an almost identical heater for my workshop. I also was having issues with how to properly power it. I was going to run a new set of 10/3 to power it, myself. But this still feels like a video tailor made for my current situation.
Same. Just got done with my first foray into French cleats. Let’s see how far this synchronicity goes!
You can also just install another plug in parallel right night to the car charger and have them both plugged in.
I have been thinking about doing this exact project and some others for quite some time. An Arduino and a few extra components are more than up to the task of interpreting the J1772 or NACS signals.
The biggest place I think this kind of usage could be useful is for food trucks. Right now, food trucks run very noisy expensive and polluting generators for power. If a food truck could use an existing EV charger for power, food trucks would be much more enjoyable and environmentally friendly. In Washington DC right by the mall, there are usually about 20 or more food trucks in a long row, all running really smelly gasoline and diesel generators. A row of EV chargers could solve this and also be used for car charging. The one fly in the ointment for this solution is that the J1772 plug only has L1, L2, and safety ground; there is no neutral. Some loads like deep fryers or griddles may natively use 240VAC, however many things are going to want 120VAC. A simple solution to this problem would be to use a 1:1 transformer with a center tapped secondary. The center tap of the secondary could be bonded to the safety ground in the food truck’s electrical panel. Then the derived neutral from the transformer could be used to supply 120VAC loads. A microcontroller could be used to monitor the applied loads, provide a visual indication of the available power, and open a contactor if the loads exceed the available power.
Other uses for EV charger power at home I have thought of include things like log splitters, pressure washers, and snowblowers which are only used occasionally and frequently get ruined carburetors from bad gas. These kinds of equipment need more power than a standard 120V outlet can provide, so having access to the kind of power an EV charger can supply would be a game changer
Another thought I have had is to use an EV charger to power an electric grill. A 120V outlet is really marginal for powering a grill in the same way that propane does.
Anybody else interested in things like this ? I’m an electrical engineer with a lot of design experience.
Fabulous video as always by the way !!!
Along with your food truck idea, you could even go as far as using DC fast chargers for power. Take the 150 kW of DC power, run it through an inverter, then have a center tapped transformer on the output. Use the same signaling for current to match the load of the trucks. This probably isn't super practical because of the size of equipment involved, but it's easier than having a dedicated service for them. You could even have a 208Y transformer if you wanted to offer 3 phase.
As far as the garage, as long as your service could handle it, there are common 80 amp chargers that really open the door to high powered applications. Similar to the industrial environment, where 480V drops are common around plants, for anything like welding, portable offices, and temp panels. At home, there's not much that 19.2 kWs won't be able to handle.
If I wouldn't have been allergic to the classroom environment, I would have loved to be an electrical engineer.
It would be cool to see a food truck-like thing made out of say a Rivian van one day. So much power on board. And it would be wise for new food truck areas to be built with 240V power hookups for all spots.
After some research, it seems like adding the product features Alec requested with an Arduino or microcontroller might be a bit trickier than it looks due to the chicken and egg problem of interpreting the Control Pilot signal BEFORE calling for power from the charger. Or, if you default to power on, then there is a problem knowing the release button is still being pushed after the power has been cutoff. @TechnologyConnections, If you are up for it, I would love to try and build a POC control board and send it your way for testing.
@@jamesgartrell4462 You use the passive components to enable AC, which then powers your logic circuit. Then use the pilot signal to control the heater's contactor.
@jamesgartrell4462 what about including a small rechargable 5v battery to carry the Arduino while waiting for the control pilot? Then once all the checks are done for connection, signal for mains power, close the contactor, and then recharge the cells and run off of a control transformer for the Arduino
27:17 That is why I love the Electrical Connectors we use in Germany:
- CEE 7/3 (Type E Socket aka Schuko) and CEE 7/7 (Type E & F Plug) for up to 16A (for continues loads it is only recommended to use 10 - 13 A max, e.g. Car charging)
- IEC 60309 (aka "CEE System") with ratings up to 125A for continues loads (16 A, 32 A, 63 A & 125 A)
> 230 V, 1 Phase (L, N & PE)
> 230 V / 400 V, 3 Phase (L1, L2, L3, N & PE)
- Type 2 for Car charging
- CCS 2 for Car fast charging
Type J wäre besser als Type E. Typ J ist einfach viel zu gross und nicht Verpolungssicher.
Einfach so geil alles dreiphasig und standardisiert zu haben.

But you can only use CCS for 8 hours with 16, 32 etc. Everything you need after that requires a fixed connection.
The best part is that if you don't have an EV, you can bring the heater to a public charger and plug it in there.
Merry Christmas!
Kinda reminds me of CCS to Schuko adapters in europe. Just imagine someone rolling up to a public EV charger and plugging in their phone!
@@oznerol256 i actually charge my laptop and power tool batteries this way when on the road.
I vote this the best comment.
If you wanna sleep in your car, I wonder if it would cheaper to plug a heater into a charger or idling the engine.
@@lajya01If you mean an electric heater _connected to the mains power grid_ (as opposed to powered by the car via an inverter), it'll almost certainly be cheaper to use an electric heater.
Idling an ICE vehicle uses an amount of fuel, per hour, approximately equal to 0.6× the engine displacement.
For my 1.3 litre (1300 cc) hatchback that's 1.3×0.6 = 0.78 litres per hour, which is around £1.05/hour at current UK prices for unleaded petrol.
An electric heater would likely need to be absurdly overpowered for car-heating purposes to cost anywhere close to £1/hour at typical UK electricity prices. I'd imagine that even a 1 kW heater would be too much to run continuously in a car.
Though obviously this depends on the car's thermal insulation and the outside temperature.

Simpsons did it! [almost thirty years ago]
24:55 - Fun fact on early Tesla's. The main 400V battery pack contactors wore out very quickly due to the arcing damage from opening and closing all the time under different voltages/loads.
Tesla fixed this by having voltage detection circuits on both sides of the contactor. When the car wanted the contactor to close, it matches the voltage on both sides of the contactor before closing. Leading to little, if any arcing. After the contactor is closed, it's then able to push through the massive amperage needed.
I bet musk is gonna remove those protections to cut costs

Only a minute in but that heater is a great picture of the future for me. There are a lot of occasional use “shop tools” that would benefit from this.
The heater is a perfect example because it benefits from the extra pixies but even table saws or compressors would benefit. Things you’d use in the garage to work “where the car normally is”.
Hopefully that comes along with ubiquitous pixie powered cars.
yup- welfder, table saw, all kinds of things need a lot of 220 the few times a month you need them as a hobbist
AC chargers will become the dryer outlet of the garage. 220V, and it's high amperage ready.
Welder! My buddy has a welder that can plug into 120v 15A or 240v ?Amp. Either way, it’s an intermittent use device that could be powered with an electric car charger outlet! I’ve tried to figure the cost of running a dedicated 240v outlet for JUST a welder for him, but it costs too much for his limited use.
@ The “problem” is that there’s no profit motive. “Big Welder” doesn’t make money off of intermittent welders, they make money off of people who make money welding.
The actual product that can come to market here (at least in 2024) is an “interposer” that handles the “pretend to be a car” part and gives the user a “safe” outlet.

"Mostly solar powered apartment complex". Sure.
@@leecasey3022 Right? Even a mobile home needs 100A at the minimum and that's assuming it's an ancient single wide model. I call bullshit on that. The solar power is additive at best.

@tsraikage 10KW is not enough for an entire apartment complex. 10KW is good for maybe 4 cars at the most. That's only 2500W per car.
@@Luke357 correct. that's what i'm saying too. during noon, full complex parking spot will not be occupied by electric cars and ones that are parked will get significantly cheap energy. im not debating over whether or not personal solar panel is good. for sure even if we could extract 100% of the solar energy from car's surface area, it's nowhere near the enough energy even for 8 hour direct sunlight. it matters when we have whole parking spot area covered but have only handful of cars charging at each moment

I may have seen these on your channel but there's smart switches that you can plug two 240v 30a devices into with a NEMA plug (there's a couple plug types available) and they'll power a secondary load if nothing is on or the primary load and turn off the secondary if both are on.
I bought one and tried it with a 5000w heater and my dryer on it (it worked) but I ended up returning it in favor of hard-wiring the heater because I'm using it to keep my washer from freezing. I generally keep it set around 50f but crank it up when I'm working out there. When I first got it I cranked it up to max on a 5F day and it got my garage to 90F, lol.
The other reason that you do not want to cycle plugging in different appliances into those NEMA plugs is because they are generally manufactured cheaply because they usually get an oven or dryer plugged in to them and then that's it. Cycling a cheap plug will eventually lead to a high voltage arc that is very likely to cause a fire.
No problem in the rest of the world! They handle it just fine.
Perhaps a switch on the receptacle, such that one could stop the flow of power to any connected devices prior to unplugging, could help?
Yeah, yeah, electric cars, impressive electrical engineering. I just enjoy whenever Menards makes an appearance in your videos.
A company I know uses heaters on an adapters like that to get a controlled load for the charging stations they make. It was cheaper than a suitable quantity of power resistors. (Which would use the same adapter but would look more... technical I guess.)

I’ve heard of some of the larger “solar generators” having a J1772 input. Since they’re approaching multiple kWh now, a regular outlet is going to take a while to charge them.
In Norway, and probably most of europe, we have both 230V and 400V plugs that can handle loads up to 63 amps at three phases. They look pretty similar to your charging cable, but are color coded with blue for 230V and red for 400V. These have been standard for decades, and are pretty much common in both industry and some home garages where workshop tools are used.
Never actually seen a single phase plug be used anywhere.
aaah! enda en person fra norge!!
@@vablo7198 they are pretty common for Camping Vehicles
actually that's incorrect. blue/red is for single/three phase
American homes only have 220-240 going in, then splitting 110/120 up or down for the standard outlets. There's around 480 coming off the street, but I think you have to have a commercial license in most states to run a line for it, which allows service stations and other things to transform it personally outside their building.

Don’t worry bro ‘they’ gonna get him.
16:54 well that actually made me think of how much energy it takes to move just 1 person(usually) in a giant metal box.
Yup.
To get order of magnitude energy reduction you need to abolish R1 zoning (to allow multiple dwelling units to share walls) and get most people on mass transit (economies of scale).
And then you realise that, with over 9kWh in a litre of petrol, that ICE vehicles require 5 times or more of the energy to move the same person the same distance. Typical ICE vehicle efficiency is below 20% in the real world, 80% of the energy in the fuel is simply wasted as heat, noise and vibration. Think about that...
@@ledsalesoz All of it is wasted as heat at the end. Unless one counts the potential energy gained by going somewhere higher.

3 phase contractors must just not be too common there
cool
Here in Argentina where we follow similar electrical standards as Europe, this contactors are also super common
@@AMalas I think you've got that backwards, what they're saying is that the contactor that Alec sees as relatively high end by US standards would be an assumed standard in the EU, implying the availability of lower grade designs in the US than what's allowed in the EU. Similar to how the EU tends to use Wago connectors for wiring where the US typically uses wire nuts.
Same here in Paraguay, South America. At home I put 3 phase ("mini") contactors to everything, my ovens, water heater, steam iron, etc, really because a like the "clunk" sound.. Generally the contactors controlled by wifi switches. So everything is controlled the same way no matter the load is. Greetings from Asunción.
Do you think during the winter months you will generally just keep the charging station plug parked up there in the shop heater? Or do you tend to hang it back on the standard cradle when not in use? When the shop heater is off, is the circuit completely off with no vampire load?
There's the glowing light on the front, but I doubt there's any notable vampire load - wasting power requires components, and that thing doesn't have many to do the wasting.
Probably not - I expect this will get used pretty rarely. And as far as vampire loads, the heater only has that neon indicator which is negligible but the charging station would hold its contactor in continuously if I left it plugged in, and that probably pulls a watt or so.

Talking about plugs, remember the video where you explore the holes used for indexing during manufacturing of the regular plugs? You probably know this already by now but in Japan they use those holes as part of a locking safety system specially for outdoor plugs (like varanda placed washing machines). You just stick them in and twist, then a mechanism inside the wall outlet will lock the pins. You CAN use them without locking and you can install them indoors too but I have only seen them outdoors on apartments and on industrial settings. You could check if you have any patreons that live in Japan that would be willing to mail them to you so you could do a video on them if you interested.
I'd look into buying and shipping those to him if he's interested. I'd just need a shopping list
We have two EVs and we've also never felt we needed to have two chargers (EVSE).
I hope a company will take your idea and make a heater like yours!
I completely agree. For most use cases, a single "charger" at home is all that is needed. We have 3 EVs/drivers on a single 20a/220v else on the driveway, and 99% of the time, it is all we need. That 1% is when I plug in at work using the portable box in the fridge or hit a DC fast charger on the way out of town.

I have an electric bike. As the chargers for these bikes have a normal household connection, if you run out of power on the road you either have to pedal yourself or drive to a charging station for e-bikes. But there are also a few manufacturers who have built adapters from electric car charging stations to household sockets. They also have to pretend that the charging station is a car, but it works. It works not only with bicycles but with all electrical devices that you might need on the road.
Problem is that your charger needs to be designed to tolerate 240V. Also you should be converting to a NEMA 6-15 socket instead of a NEMA 5-15 socket.
If, at some point, somebody manages to produce an e-bike battery that could recharge itself in 5-10 minutes, being able to use car charging infrastructure to extend your range would be awesome! (Hopefully, the charging adapter required to do this would not be too bulky to carry on a bike).

As a European, watching you talk about the different nema plugs and electrical systems in North America always kinda scares me.
Over here, we have basically 5 types of plugs, including two very rarely used ones and also two three phase connectors (16A and 32A).
Our the charging plug is very similar to yours, but it has a electronic locking mechanism so the car and/or the charging station can prevent disconnection under load. You would have to switch off the resistor at CP (or rather change the resistance) to be able to unplug the cable.
Almost all of those are very uncommon. In residential settings, we just see 5-15 for 120v (what the rest of the world thinks we only have LOL!), and 14-30 for electric dryers and 14-50 for electric ranges. All those other types are either legacy/now out-of-code (the 1-, 2- and 10- series) or for very special-purpose commercial or industrial purposes (especially the 3-phase versions). And then, usually stationary 240V or 277V 3phase appliances or machines are often just hard-wired. 😉
_edit:_ couple of dumb typos
@@youdontknowme5969 Ok, that checks out.
Still I probably won't need to mention the dangerous flaws that the 5-15 has (as well as the 14-30 shown in the video) because you surely have seen Alec's video about that as well 😉 I have found out though, that there are in fact "L" versions of the nema plugs. How common are those?
I mean Europe has it's fair share of obsolete and weird plug standards. I think the difference is that it was much easier to get away from them because of the universal 3 phase 230/400V supply both to most residential homes and to commercial buildings.
There just never was a big need for a plug that supplies more than 16A on a single phase at 230V. Anything more power hungry can just be connected with an appropriate CEE plug or is hardwired. There just was less incentive to add plug standards.
Well done; love that you’ve tackled this!
well huh, more than heaters, welders, lathes, mills, planers, jointers etc. There are a lot of tools that a home shop can use that currently require dedicated wiring, but realistically, a lot of people only use one tool at a time that would require the 240.
So, I see a bodged together multi-outlet adaptor that goes on the end of the car charger cable and is able to take the plug from various machines.
This, is going to get interesting.
A 240v 50A "power strip" with an internal breaker? Sort of a portable sub-panel. I like it.
He mentions the government investing/focusing on home charging. The scary part of people charging at home is that they are unlikely to inspect and maintain it, especially if they have little or no money. This can lead to fires that could burn down entire apartment buildings, especially if people try to do a project like this heater. I hope we will all have electric cars and home charging, but when we do, it will become a need instead of a want, and the electric companies and government wll then raise the fees as high as they can, and that is the sad part. On costs, it is probably better for people with electric cars as long as electric is not the mainstream.
@@itoibo4208 i’m also terrified of gas lines getting installed in homes because the chances of those getting maintained constantly are slim. If those leak they could cause a fire or even explosion or just suffocate people. terrifying!!
Meanwhile is Europe a 400v 3 phase is standard and you can just plug anything. Recently I was plugging 125A machine with just a plug.
@@thekingoffailure9967 yes. gas in a house is crazy lol
21:00 I wouldn't use relays in this kind of circuit - high power relays with high current ratings are expensive and should be avoided. The easier way would be to have the heater refuse to turn on if the configuration is set to the wrong amount of power. This could be achieved with a 3 way switch and a small sensing circuit, avoiding the extra cost and providing more safety.
EV charger style connectors designed for repeated insertion and removal without wearing out the connector honestly should be more common. Mostly unrelated to the subject of the video, but I could see a J1772 or similar connector becoming the standard hookup for RVs/campers at powered campsites.
Love this project and video. Thanks, Alec! 🔥
