Tesla Model 3 - Home Charging with a UK 3 Pin Plug
ฝัง
- เผยแพร่เมื่อ 1 ส.ค. 2024
- Charging your Tesla Model 3 at home with a standard UK 3 pin plug has been my primary method of charging for the last 4 weeks. Is it actually a viable option long term?
Buying a Tesla? DO NOT forget to go via a referral link for 1,000 free supercharger miles. Here's mine ;) ts.la/jonathan34206
Let's be honest, we all love the UK 3 pin plug, but how useful is it when it comes to charging your Tesla? I'm looking at the pros, the cons, and the maths if you want to keep your charging properly old school.

Another useful video, thanks for this. UK produced content is refreshingly independent.
Nice to hear Andy, thanks again!
If plugging in next to the kettle, you might want to avoid turning the kettle and car on at the same time :-) Nice video.
Kitchen is the worst place to use. Kettle is OK, but kettle plus toaster will exceed the limits of a single ring.
Just picked up a "new to me" 21-plate long-range model 3, this is really helpful, as I don't have a wall charger fitted yet and it's likely to be a couple of weeks away yet. Thanks!
the most practical advice ...nice
now i can get a tesla
Thank you very helpful, I can see you went and put the 32amp Blue Commander Connexion (it's showing on my recommendation) . I'll be watching that video next.
This is definitely a good option if an outside charger is impractical or not cost-effective. I charged like this for several months and, since I don't have a regular commute, the charge was always sufficient for the next day. I do now have a 7.5 kWh charger installed. There's the cost of electricity to consider. I use the Octopus GO tariff which enables four hours of night-time charging (between 12.30 and 4.30 am) at a reduced 5p per kWh. So it pays to push in as much power as possible during those hours (my standard rate is 13.96p/kWH). With a start-charge time of 12.30 and an 80% ceiling, my car theoretically loads 30 kWH from the 7.5 kWH charger in those four hours. That's £1.50 for about 100-120 miles of driving. Most times it stops charging before the tariff change because the battery has reached the specified level. That's more than enough for me. However, the 13-amp socket route is still a good contender. You just need to do the maths. Good informative video, by the way.
Thanks exactly the video I was looking for in my ongoing research into whether to go over to EV. I am retired but occasionally do a 200 mile trip so this is feasible.
Just found your channel and subscribed, they’ve been very helpful in learning how to do things, thank you!
Thanks for the info on 3 pin charging , well explained..................
Very interesting and informative. You made some valid points.
Thanks for all the useful info! Cheers!
Rest of the world is lucky as you guys get 240v connections, here in USA we get abt 5mph on a regular house plug since its only 120v. Model S and X even less
Brilliant video thanks.
Thanks for the info 👍🏻
Really helpful thank you
Thank you, you answered my worries (A - does it come with a standard 3 pin plug /adapter) and (B - what range am I expecting per hour =10 miles roughly, so easy to calculate) 👍
I found your video very helpful indeed. I’d like to get an Audi e tron but my house electric is on a loop with 3 others so that would mean un looping all the houses, very expensive and I don’t think the neighbours will be up for it! So top up charging would be great for me once the car is at a 100% I’ve googled public charges near me but only 3 come up and I’m sure that can’t be right, there must be another way of finding them! Anyway, like I said this was very helpful as everyone says you shouldn’t use the 3 pin plug as they aren’t safe! Thanks again for the video that I’m sure has helped lots more than just me. Cheers….
Had no idea that a commando charger could offer the same speeds as a dedicated wall charger. Great insight! As the Tesla lets you choose when the charging takes place the same way a ‘smart’ wall charger can, I’ve often thought it seemed like overkill to have two devices capable of doing that. I guess the only other benefit of a tethered charger (assuming you haven’t got a huge solar array capable of funnelling charge to your car) would be having to connect/pack away your cables after charging…but still it’s another opportunity to save.
I went down the Commando route to minimise the cost of providing a charging capability at 3 locations - 1x 7kw adapter cable and the three locations just needed the dedicated 32a Commando feed installed which cost a lot less than a dedicated EV charge point.
Exellent! Thank you
Good video mate. Thanks.
Thanks mate
Haha I searched for a video on this and couldn't believe it was you Jono, (Dave from Leicester Uni)
Haha, hello mate! Hope you're good!
thanks for sharing 😎👍
Thanks! This is very useful!!
That was very helpful 👍🏼
Another good video thanks…do new Tesla’s come with the 3 pin plug as standard? I have just ordered a model Y long range, thanks.
Smart charger is the way forward so you can take advantage of different charging rates, for example with Octopus Go.
Nice music!
very helpful, .. thanks... need to make the same decisions myself now, .... picked up my tesla 2 days ago from Manchester Trafford with 45% charge (why not fully charged :-|) , ... nearest supercharger is 10 miles away.
Thanks, glad you’ve found it helpful!
Thanks
I recently bought a Zoe and was a little surprised that the efficiency of charging varies quite a lot with the power available. So charging at 32 amps or around 7.5kw is about 90% efficient for me i.e. when comparing the power you pay for and the charge left in the battery. Using a "granny cable" however at 10 amps you only get about 1.5kw and not the 2.3kw you might expect or the 2kw you saw for your Tesla. This is because the Zoe's internal charger carries a fixed overhead and is only about 65% efficient with the granny cable as compared to your Tesla which was 87% efficient. Something you might want to check before buying your car if you intend to use a granny cable a lot.
Did the wall socket get warm after drawing 2.3 KW for an extended period as I have ordered a Masterplug 3-pin EV charger for the small EV (Zoe or Fiat 500) that I plan to buy soon, prior to having a Zappi installed at a later date? Good video, BTW!
So now had our SR+ 2 weeks and intended to get a home charger when we move. However, I cannot warrant getting one. We have low mileage and the odd longer journey to the mum-in-laws would require a charge on the way anyway. At the moment I'll stick with the granny charging and no plans to get a home charger when we move.
brilliant just the job
I did not know you can use a 32A supply. nice
Expecting my first Tesla in the next week so enjoyed this video. Great information
We've only had our SR+ since yesterday, we're retired and no daily commute and only occasional long trip. We have no need of a home charger and happy with granny charging.
Great vid
Does your 13A plug get hot after few hours? Or just warm?
What would the increase in normal electricity cost be, say per charge, if standard 3 pin is used ?
Mate I hope you come back and make more videos soon
Thanks mate! Moving house and the various subsequent things to do in relation to that have been taking all my spare time up. I'd like to get back to it soon, although I need to have a think about the content as I covered pretty much all the "basics" that I wanted to when I first started out.
Very useful video. Can someone please tell me, when you charge it with a 3-pin plug, can someone remove the charging cable from the car or is it locked in!
Hi thanks for the video, the 2.3 kWh would that be on all Evs or just the Tesla, I had a bloke come round my house and said to get a proper charger it would cost me over 2 grand to fit because my electric box is at the front of the house and my garage is at the end of the garden.
Very helpful..... you can't use your car in the evening as it needs to be charged for the commute...
Different folks,different strokes,as they say.
I've still not got around to installing my wall connector in over a year...3 pin has been fine and I e now done 15k miles...
Nice, definitely a viable option longer term then! One thing I didn't touch on in the video was the potential wear and tear to the 3 pin cable if you're using it outdoor full time - have you noticed anything like that or is it still looking good?
@@jdhartwell732 yeah so far it's fine - a few scuff marks but that's all
I plan to use a 30m extension cable (from 3pin socket) - I was told to unwind the cable from the reel first. Is that necessary, and if 'unwound' what does that mean - will an untidy pile of cable on the floor suffice?
Very informative, thanks. So, the car has to be unlocked to commence charging, but once it is charging you can lock the doors and it will remain charging?
Hi Joe, yep that's right in that it'll remain charging while locked.
My journey to work is only 8.5 miles in total each day so I wouldn’t ever need the wall box
Thanks for the video. It's helping to sway me more towards 3 pin home charging for my upcoming Tesla.
Do you have any concerns about cable theft? Could somebody just disconnect the cable whilst charging?
Thanks Ash. So technically the cable should stay locked to the charge port - however, I have read about situations where people have managed to get it out via either brute force or some other method so it's not completely theft-proof. I think if I was going to be regularly leaving it out overnight charging, I'd probably look at a way of securing the cable itself to the car somehow just to be safe.
@@jdhartwell732
Thanks. I'm actually in a very similar situation to you - staying with my parents during COVID with the occasional trip to London for work. I rent in Greater London so I can't justify installing a EV charger on a none-family member's property!
Late to the party, I've set my to 10a charge from my garage. The plug it's connected to is a double plug coming straight off the consumer unit (CSU is in the garage too). Some nights the car will charge fine, other times the RSD trips straight away?
Interesting …
Does it stress out a normal extension cable?
Or cause any heat issues to the in-house plug socket?
How has it effected your electric bill? (& Do you know what your p/kWh charge is re that cost?)
Thanks.
Good question re ext cable. I was just told to unwind the cable from the reel which I've done (it is now in an untidy pile on the floor, so not sure if that is sufficient)
How long does it take to charge with a Tesla outdoor charger?
Just wondering what it costs to charge in this way? At today’s energy prices. Thks
How much it cost bro for overnight charge, ty
How much did it cost you to charge your EV up from the 3 pin wall socket please? Thanks
Great video, thanks. I'm getting my model 3 next week and will be parking on the street but will be using 3 pin charging when possible. Stupid question from me, does the 3 pin plug adapter come with the car on delivery? Or is that something I'll need to buy separately? Cheers
Hi Jack, you'll get the standard 3 pin plug with the car on delivery. Enjoy!
@@jdhartwell732 Thanks for replying, really appreciate it
@Jack Telford How are you getting on? Are you using an extension cable with the Tesla 3 pin cable to charge your car on the street? Are you running the cable over a pedestrian pathway?
@@AlexN0me11 i live in Brighton and there happens to be an electric blue charger near my flat. It's on street parking and attached to a lamppost. To be honest I could probably get by without even using that. I tend to use one of the superchargers after a long drive which I do 1/2/3 times a month which gives me enough battery to get around town. First few days I had range anxiety but you quickly adapt. Zero regrets. It's an incredible car
Great video buddy- refreshingly concise and succinct; will definitely have a go at just using the 3-pin for a few weeks to months to see if it’s manageable before plumping for a formal tethered charger. Do you know if there’s any issues that will develop for the home breaker box if you’re regularly charging for prolonged periods eg. 24hrs?? I can’t seem to find anything online about it.. 🤔
Thanks mate! Hmm, I've heard and read about people using the 3-pin full-time, and the electrician seemed to think it would be a viable method, so I've got no reason to thin it would be a problem in terms of using it for prolonged periods, but I've not been able to find anything online about that in particular either!
Where Can I get it? It’s not on the website
Can you use an outdoor proof cable reel extension adapter to connect the Tesla 3 pin plug into?
Not recommended,but if you do unreel ALL the wire,to prevent heat build ,don’t leave some coiled.
Does it automatically set to 10 amps on the computer?
4:22 and how much did it cost to charge overnight plz mate ?
OK some of you will probably read my comments below and mutter that surely a 13A plug will only take a maximum of 13A ? Uhh not strictly true IF the plug is manufactured to take a higher rated current AND the cable to the car is rated also at that higher current rating IF it is plugged into a 30A rated power unit re supply.😶
Have you got a model 3 long range?
Great video. Do you find you are charging the car daily? Does that still work out better value than petrol/diesel? I fill up once a week and get about 400 - 500 miles +.
Thanks! I think as a pure cost per mile the electric comes out quite a bit cheaper, but for 500+ miles a week you'd be looking at at least a couple of long home charging sessions.
@@jdhartwell732 Thanks JD. May I ask what your long term plan is for the EV as the battery degrades over time, and so will need charging more often? Do you 'rent' the battery from Tesla, or do they offer replacement... or is the only option to trade it in and they recycle the EV?
@@SootheSound Have to admit the battery degradation isn't really something I've considered - my main concern was the degradation of the overall technology (perhaps degradation is the wrong word here - what I mean is how the much EVs will have advanced in the next 3 years, relative to what's available now). This was one of the main reasons I only wanted get it on a 3 year lease.
@@jdhartwell732 Thanks JD. Yes, that is a good point. I intend to keep my diesel for several years, so take your point. Leasing allows one to forget about battery degradation.
Domestic 13amp outlet is not designed for continuous use. 32amp dedicated commando socket on 6mm cable stepping up from 4mm would pay for itself in heat losses. Having a proper charger install would allow for EV charging to be paused while other high power devices are in use, elec shower.
How much does this cost for your electricity bill? Would it cost the same amount using the three pin plug, or a tethered charger?
Costs exactly the same. But you'd have to pay about£500 for a charger
Hi, can you add an extention lead (10m) will this effect the charge time etc?
It's considered dangerous, mitigated by using an industrial outdoor cable
I charged my previous EV in numerous places - hotels, B&Bs, parents' house etc - many many times over 5 years and never had a problem. It had a 70-mile range, so leaving a B&B in the morning fully charged was a real asset! But it's worth knowing that problems *can* occur and being cautious. You're adding several extra connections, and they need to support 10+ amps for a very extended period. You need a good extension lead: don't buy the cheapest, make sure it has a high current rating. Make sure all the connections are firm (and waterproof if relevant), and *make sure it's fully uncoiled*. It should work fine for occasional use, on holidays etc... but I'd be hesitant about doing it regularly. Also, if the wiring of the socket doesn't look great -- I've plugged into single spurs in people's garages, for example -- it would make sense to turn the current down. And then check everything after the first couple of hours - are any of the plugs getting hot? It's not unusual for them to be slightly warm, but there are also plenty of images on the net of completely burned out plugs. As long as you're sensible and cautious, extension leads should be just fine, but use at your own risk! Commando-type connectors and extension leads will generally be much better if they're an option.
Do u think semi detached house it’s safe to keep charger from inside of house crossing pavement Infront your house to plug in the car?
You can buy a rubber strip to put the wire through. An other people can walk and drive over.
The Tesla charger charges the E-208 at 18mph using the standard 3 pin plug - very handy
This is good to know 😊😊
That sounds incredible? So your car averages about 9 miles per kWh? Never heard of something that efficient!
@@CarFinanceSimplified absolutely! We discovered it through having to use the Tesla charger as a last resort, amazed at the charge rate from a standard 3 pin! Used regular now
@@adrianmathieson1967 That's nuts. So what range do you get if you don't mind me asking? Must be at least 400 miles?
@@CarFinanceSimplified the range is 200 miles or so - I was only referring to the charging rate
Do you get the 3 pin charger with the car do you no???
Is the cable thin enough to fit under a closed garage door?
No
depends on the size of the gap! 🤣
why limit to 10amps? Have you tripped it as most sockets will take 13amp without issue
Tesla limit it to 10A to protect the house circuit, eg in case you plug it in to a double socket next to another appliance, and it is a constant draw on the system for a long period of time. this allows the cables in the house to not over heat/wear out overtime.
I think I'll stick to hybrid. The charging on electric cars is not practical enough for most to change. Ues your saving on fuel but at what cost?
I'm surprised you didn't mention the potential hazards with using a standard 3 pin socket. You don't have pen fault protection, DC leakage protection and can overheat a standard internal 3 pin socket with prolonged use. Also I have to mention that I had to turn the sound off on the video and use captions because your background music was WAY to loud in the mix. I really struggled to focus on what you were saying.
No refference to electrical safety, only cost.
3 pin (granny charging) is only recommended for charging now and again, and not for constant use. It is the equivalent of having your kettle switched on for 10 plus hrs a day/night. The 13A socket can take 10A, but can lead to a premature breakdown if constantly under a consistant high load. Please do not reply saying you have done this for x amount of years and all is ok. Its like saying youve been driving without a seatbelt for x amount of years and you are still alive. Your EV manufacturer normally cover themselves with granny charging, stating that it is for occasional use (i.e. top ups at the office, or an air bnb etc).
There is also other protection that is required when charging a car, such as 6ma dc leakage protection, type A RCD (most existing rcds are AC that will not work if DC is present) and PEN fault detection or an earth rod. House sockets generally wont have any of this, which can ultimately lead to an electrical shock.
Price is regardless, youve probably just spent 40k+ on an EV. 600-1200 for an installed point should be nothing in comparison.
The thing we have to look out for is the government is not charging tax on this electicity apart from a tiny bit of VAT. At this moments high electricity price it's Tesla 8 pence per mile and diesel 12 pence if my sums are right. Personally I would prefer the tax was added to the MOT cost where millage is checked. 3 years of not paying would be fun for the first years. Never forget that the Tesla is cheaper to run due to this trick. This won't last. 10 amps is a rather old fashioned charge rate for 13 amps. Probably wise not to make it more. If your charger fails check the 13 amp fuse as a charger is a tough load. I have great doubts that we will have enough electricity to go fully electric. That's fine if we are allowed to use our diesel and petrol cars up to scrapage. As things stand only nuclear could fill the needs. Bad as it is that's the best. Gas is unrelaible even if we accept to do that. Guess what. It won't make a scrap of difference to climate change because China, USA and India can not move fast enough. Not that they don't want to, they just can't. Glad to be wrong on that.
I appreciate the effort it took to make this video, but why did you make it? if you can afford a Tesla model 3 at 40K it is frankly silly not to install a 7 kW charger for a few hundred pounds.
⬆️👆👆thank to the group Same thing happened to me. I live in Florida and there’s a lot of lighting.
Love my diesel
haha, and the particulates it puts out.....
Did you say you have to leave the car unlocked ???
⬆️👆👆helped me out now my problem has been solved
WHAT IF I WANT TO USE THE CAR IN THE EVENING INTO THE EARLY HOURS AND THEN I NEED IT FIRST THING IN THE MORNING.... NO THANKS, I'LL STICK WITH MY ICE AND WATCH THE TV SHOWING ALL THE CARBON BEING RELEASED INTO THE ATMOSPHERE FROM ALL THOSE WILD FIRES AROUND THE WORLD
you shouldn't be using a domestic socket to charge an electric car, its for emergency use only.....having that drawing that much current for 10 hours is dangerous and could not only short out your board but could easily overheat and catch fire.....totally irresponsible to even suggest people do this
OK Informative vid BUT not entirely accurate. '10A maximum you will get from a UK 3 pin plug'??? UHH NO! If that were the case then your electric cooker, hot plates and oven would burn your standard 13A wiring out. A cooker plate with a 3 pin socket gives out up to 30Amps IF wired correctly (and do remember that in the UK ALL and ANY modifications must be carried out by a qualified electrician or electrical engineer. ) 👀SO that 30A socket is wired as is the unit from power delivered from the main power supply to it along a cable capable of supplying up to the fuse rating, generally 30A. THUS I suspect if you have one of those as you appear to be charging from the kitchen, then surely adjusting the charging rate on the Tesla control point it would charge faster? 👀I'm not knocking how you show it can be charged at a lower rate I am merely stating what is FACT re that 30A supply HOWEVER, some places have GAS installations and cookers etc and NO 30A supplied units etc. So that would not apply. Personally I suspect many people will have a 30A supply wired to their garage for the EV charging point and that in itself would not be too expensive. ? 👀Lastly, a standard what we in the UK call a 'ring circuit' is subject to whatever is plugged into that circuit that is drawing power from it? That will increase the load on the main 'ring circuit' as will the charging of your Tesla and certainly IF it is drawing 10A? That's a heck of a lot of power putting a strain on a circuit that may already be taking amps from a heater, electric kettle, dual electric cooker rings.. etc That ALSO applies if you plug it into the 30A supply 👀IF you have the cooker working and drawing x Amps plus the rings on PLUS PLUS more Amps HOWEVER a 10A charge to your Tesla in that case would probably be safer than taking it off the 'ring main'. You would do yourself a bigger favour by taking the power IF you insist on using a 'ring circuit' from the upstairs socket as this is often on a separate 'ring circuit' of its own. Many 'ring circuits' cater for up to 15A though plugs of course are rated 13A AND do remember that the FUSE contained in the 13A plugs is rated correctly. There are 3A, 5A, 10A and 13A ones in circulation. An electric cooker with 4 ceramic hob unit on full power can easily take up to 15A of power. If you want to charge your EV at home invest in having the power supply upgrade to your ie garage etc. Long term it will be well worth the money?👀
Electric car are not the way.. rubbish
The video is really helpful. Thanks !!
One unrelated question . Could you please let me know which floor mat are you using on your Tesla , it looks really good. Thanks!!
