@@eugeniustheodidactus8890 I believe Tesla looked into this in detail. I remember Elon speaking about it years back and saying it's not cost effective or practical due to it low KWh charge. plus he has the robot arm charger when the robo-taxi come into play.
you don't want this. the normal efficency (charging via cable) has a 20% loss, that is 20% lost to air, this is reasonable. Wireless charing is a 50% is the distance is minimalised! that is half the electicity that you're paying is wasted. gone in the air! i'm not paying for double the electricity and only using half of it.
Wireless charging is the obvious choice in view of autonomous driving. I hope that all car producers including Tesla will adopt this with the same standard
It is not the "obvious choice" ... Tesla has not adopted it because it does not work, is not reliable, and is not cost effective. I wanted to believe it too, then I did my research. I carefully studied the schematics, hired an electrical engineer, and went into the field to try to find even 1 successful installation. In the end, the conclusion was "obvious" ... charging a tooth brush or a phone is one thing ... charging a car or bus wirelessly is another. In my opinion ... it is a fraud. I own 2 electric cars ... Tesla Model 3 and Nissan Leaf.
@@stuartmccoll4749 I doubt Matt Ferrell will be sending fake news! How do you know that it does not work with + 90% efficiency and can charge with a minimum of 11 kw. That it cannot function as a vehicle-to-grid?
I actually really enjoyed listening to Alex explain the technology and vision. He had a very pragmatic and technology-oriented approach without any of the corporate hubris and hyperbola you typically hear from marketing folks. I hope this standard makes it.
Thank you Matt Ferrell for this video, at the beginning I though this was just hyped technology that wasn't ready yet nor would ever will, then I paused I searched the J295 standard, searched the magnetive resonance power transfer and now I am impressed that wireless charging is practically as effective as plug charging. Thanks to you I learned something today.
Thanks for a nice look towards the future of wireless charging for EVs. One thing I missed was a discussion with the Witricity representative on charging effects. On their web-page it states effects of 3, 7 and 11 kW, while the guy mentioned 20 kW in the dynamic charging scenario. With super-chargers capable of 150kW and even 250kW, this would be a relevant topic to discuss. Especially in the context of dynamic charging situations, where you would have access to charging during shorter idle times or queueing scenarios and in those situations effect is highly relevant.
Alex did touch on that topic when we were talking. This is slower than fast chargers, so it makes the most sense in stationary charging locations like parking lots, garages, etc. Alex told me that we'd still need to rely on plugging in at fast chargers on longer road trips (at least for now). Unless we start adding these embedded wireless chargers into highways to charge as you move. At that point you'd never have to stop and charge ... ever. But the cost of adding them to roadways would be cost prohibitive on a large scale.
Low speeds make sense if you are doing it 24/7, and remember supercharging is limited to about 20MW by Tesla, also as you increase the power you will produce more EM radiation and will require more shielding in the car..
@@UndecidedMF It would be interesting to know whether there are hard physical limits to this technology and to how much power it could scale up to. It might also be a viable option for long-haul-trucks in the parking lots where the drivers sleep if the power can be scaled up to get a full charge overnight.
You don't need that much energy to maintain your speed. It's acceleration that consumes energy. I would like to see charging areas on the highway. Maybe a 3 mile 20kw strip every 5 miles or so. That won't fully recharge your car while driving but it would extend your range quite significantly.
@@UndecidedMF Did he talk about creating a standard for identifying the vehicle (owner) to bill for the charge? Like the Tesla Supercharger network the communication down the cable identifies the VIN and the owner. There needs to be a standard like this to make adoption straightforward. Love the video by the way.
@@milesforrest6920 It might be simplest to use an EasyPass type transponder or one's actual EasyPass. Ultimately it will come down to a question of cost.
Wireless charging for EV is gonna be the most revolutionary thing of this century, if we can do it. It basically eliminates all the cons of EV and possibly ends the ICE vehicle industry as a whole. Great topic and very informative video Matt...loved it!
Thank you for covering the efficiency angle. That was honestly my biggest question about this solution. This is an amazing development to allow much easier implementation and deployment of charging services. I do wonder if it can support super-charging speed though, or if it will require a parking lot to have these pads in a majority of spaces within the next 30 years or so.
the bus company in the town where I live is switching to electric buses and they are using an overhead arm with an induction charger that the bus drives under. the charging station is built and the buses are being built and should be ready by July 2020.
@@UndecidedMF All these technology are in the back burner because the keep the price high. With these technologies the battery size can be reduced by 70%. www.greencarreports.com/news/1110571_renault-qualcomm-show-off-electric-car-road-charging-at-60-mph. eroadarlanda.com/the-technology/
I really like how Matt always asks the questions that would be in most people's minds and address them in the video. Very calm and clear narration, mixed with puns... I am going to stop before I sound like a fanboy :)
Love the idea of wireless charging in the garage. Sign me up!! .... I want the embedded charging unit on the interstate. Have one lane the dedicated EV lane with embedded charging and you'd never need to stop except to eat or go. That would be the cats meow for sure. Keep up the good work Matt!!
I was thinking the same thing Brian, not necessarily an EV lane, because as Roger said all cars will eventually be EV’s, but a charging lane or lanes. Not every car would need to be charged as some would have been charged at home....it would definitely provide less range anxiety.
What I like about your channel is that you bring a lot of new info, new tech, and you're not only focused on Tesla or daily stuff...Good luck! And hope to see more of your videos soon!
Nice job, Matt. Good questions, excellent instructional graphics, simple, informative interview, hitting the salient points. You earned a thumbs up. Of course, there's always room for improvement :) More specificity of price (adding cherry wheels can cost between $800.00 and 10k, same with sound system.) Also, more info about real world logistics - what would be entailed in retrofitting my car: Still need 220 out to my driveway? Pad security (outdoor) if I don't want to rip up the concrete in my driveway, cost for car stuff, pad stuff, additional electrical equipment, need electrician, how does the foot of snow on my driveway effect it; nut's and bolts stuff. Of course, this could prolly be a whole nuther vidio :). But still, good job Matt.
Thanks for the feedback, Mark. We did dance around some of that, but not explicitly. There were sections I cut for time that might have helped. In short, the pads are very, very safe outside. They work under water, snow, etc. I wasn't able to get a clear price, but it sounds like we'd be talking a few thousand dollars right now (prices dropping over time). Retrofitting is a no-go according to Alex ... at least DIY retrofitting. A company, like Tesla, BMW, etc. offering their own retrofit would be another story, but I doubt that's something that will happen. This is most likely only going to show up on new cars.
This is brilliant! I've been wondering for some time why induction wasn't being pursued. Glad to see it has been. This is one of the biggest factors that will help with adoption in my opinion. No plugging in, easy charging in any parking spot, potential charging during driving etc.

@@alexgruzen942 that last sentence could make a good slogan for you guys, didn't expect you mr.Gruzen to be here in the comments section, thought it was copy-pasted from your website.
this is another step in perfecting EVs. imagine a recharge lane on the highway, or city centre roads fitted with these wireless chargers so you drive without using your battery. and in the future everyday short commute EVs will have tiny batteries and will be driving on wireless electricity. Thank you for this vid, made my day!
Wouter M I’m pretty sure they are seeing it as a ‘top up’ thing like home charging. As development continues, it may be that they can up the charge rates.
The BMW that was shown in the video has 3.2kW, that's around 20 hours for a EV from today. It's kinds of land to make a 20 minn video without a single number beside of a questionable efficiency compared to cable.
Loved this video and the idea! One of my gripes with the many ICE vehicles I've owned over the years is that the stupid gas/diesel fill is on one side or the other. WHY NOT BOTH? So it'll take some slight adjustments to the design and add a little to the cost of the vehicle, but come on. So why am I mentioning this? Because the same can be true of having to plug in your electric vehicle at home. Which side of the vehicle do you mount the wall charger? Which side of a multi-car garage do you park on? For those cars that have the charge port on the front or rear, same type of issue if you vary pulling forward into your garage or back in. With this wireless charging (and if the receiving unit on the car is centered) it won't matter how you like to park; it'll just work. And the efficiency of wireless charging is no longer an issue. I love it!
ah yes game changing technology noting like paying double the price per charge they say its as efficient as a plug in but guess what that's what they said about cellphone wirelesses chargers and there 59% efficient not 90% as a traditional carger.
Fantastic interview Matt. 👍 EVentually, every vehicle parking space in shopping centres, work carparks, home garages and driveways, etc, will have wireless charging capabilities. What an exciting time to be alive! I hope this technology is implemented with stealth within 20 years. Imagine if you can charge almost anywhere you park your vehicle, easily and efficiently. Another fantastic invention that warrants praise. 😉
Elon needs to let us retrofit our Model 3's with this technology. What's more, the idea of my car battery essentially becoming a power wall for my house is amazing.
My question is, how much does this impact battery lifetime... Currently I only charge every three or four days as I only need arounmd 30 to 40 miles a day. Now if charge those 30 miles back up every day would this be a bigger impact to lifetime compared to charging 150 miles every few days.
@@Silver24mc Ok but then it's again something I have to actively do... but anyway I'm sure it'S possible to program a system that lets you set conditions. Like " if under 30%, charge car to 80%, offer energy to grid until 50%, start charging / preheating 30 min before I leave for work"
This is not "low cost" ... even the video does not claim it to be "low cost". It is extremely cost prohibitive ... if it works at all ... and they have not proven in the field it even works. They claim somehow wireless is the same efficiency as a copper wire ... and that is simply not true. If that were true ... why would we have wires at all ? Everyone want to believe it ... but it is not true.
@@stuartmccoll4749 it's relative, 1-2k for wireless charging at an early stage in the game is relatively cheap for the level convenience it gives. Well I'm going to believe the manufacturer when they say it's as efficient as hardwired options. I'm sure companies that use their tech have tested this, it wouldn't be hard to test.
Love it! Possibilities are endless! Watching the autonomous taxis, however, I was amazed they still look like regular old cars with steering wheels moving and a front and back seat. I am mentally designing a vehicle with lounge seating, ramps for loading luggage on wheels, no dashboard. It would be more like a room on wheels. And, before long, we probably won't even have wheels!
I would love this thing! What a no brainer. He said early on that the efficiency was the same as plugging your car in. Not having a big ugly cable hung on my garage wall or having to plug and unplug my car all the time would be great. The part about being able to connect the device to the grid is just icing on the cake. Sign me up!
I'm more excited about about the other side of the idea that you can also reverse the polarity or the components and contribute electricity to the power grid. Imagine driving over a coil on the highway where at the toll booth would give you a reduction for contributing to the power grid.
Tx for bringing this to us, Matt! 11 kW charging speed is plenty for any overnight charging, which is 90% of the charging time your EV will ever do. So this wireless charging variant that leaves some room for positioning error, is THE solution for all of our city folk that doesn't have access to off-street parking, opening up EV driving to the wide masses. Puzzled still why Elon doesn't believe in it - is there any first principles reason NOT to support this?
Matt , great review and reporting, well done . This is a game changer . The wireless charging players spent the last 10y to lobby and build a global standard for all and any cars, who needs the equivalent of a plug format war. The simplicity, efficiency , compatibility are key factors for EV to succeed. This has enormous potential. 👍 to Your Question, I’m definitely interested. Time for SurveyMonkey?
not only do you not have to remember to plug in, the lack of standardization of various plugs across different brands will no longer be an issue as well. the vehicle to grid aspect is truly very exciting as well, it renders a vehicle as an energy investment that double-duties as a tool for transportation when necessary (with shelter in place, who knows, maybe ppl would've adjusted their lifestyles to have become less car dependent whenever it is when this all ends)
@@Muppetkeeper This video is about charging in parking lots. As for charging in garages, like I said, the wired charger in my garage does 11-12 kW so the current wireless version adds very little other than some strong electromagnetic disturbances that I can probably live without.
Arth Denton I think it does add something for people without a garage or a driveway, being able to charge in the street without trailing cables is important, and this sort of charging does not need 100kw.
@@Muppetkeeper You may have something here. Indeed, wireless charging while parking could make life easier for city people. Hopefully, they can design faster wireless chargers but I can see how it may not be easy because of the strong electromagnetic disturbance this would generate.
fully 60% of the cost of a good solar system is a battery pack. having your car supplement your solar storage would be simply AWESOME. best of both worlds.
I would recommend that you actually look into the physics of this. I worry about the magnitude of magnetic fields these will need to be efficient and what the side effect of these fields will be. What are the EM emmissions, how does it affect any magnetic media in close vicinity ?
Yeah I've heard it's actually possible to wirelessly charge pretty efficiently... if that was the case, I'd love this in my garage although it's not really necessary. But for public areas? Aw yeah! Did you get a new camera? Looks great.
So magnetic resonance is the magic bullet that achieves nearly perfectly efficient transmission of energy between two coils of wire irrespective of alignment or distance? It's not the first time MIT have publicly backed snake oil.
Wow, this is great. I remember hearing about WiTricity in Apple rumors and hoping that Apple would implement it for powering wireless keyboards, mice, headphones, etc. It would have been great for the iPhone (or any phone) if it could be small enough. Hopefully it could still happen for everything needing power.
Here's a suggestion for a future video: try to go a month without charging at home or at work. I've recently moved out from my house that's being remodeled and the apartment doesn't have any charging. The local Tesla Supercharger for my Model 3 is always too busy, so I've been pulling my hair out trying to keep my car charged! But I've learnt a lot more about options such as the PlugShare app that can help.
There is a critical question that I wish was asked: how far can the plates on the ground vs in the car be? Will something like a raised Cybertruck be able to charge as fast as a plugged in charger with no efficiency loss? Also what is the charging speed??????
this is indeed a valid question, one which I also want answered... like how far is the range, and how much does it "lose" efficiency by range? Is it same efficiency all ranges, then at a certain range doesn't work at all? Or lose more and more efficiency the further away, but still work, until too far away simply not efficient any more?
Seems promising to me. Thanks Matt! I may have missed it, but I don't think I heard any mention of Tesla in the video. I'm sure you must have asked the question...
@@UndecidedMF Tesla is against wireless charging, Tesla was asked to supply the pace car for formula-e they declined, the organizers wanted the pace care being wireless charged, Tesla did not want their car being charged wireless. I don't know how if they will change their mind in the future but would probably use their own system what is not compatible with this standard. Tesla is a bit like Apple with standards, don't like to play with others.
@@buddy1155 That sucks.... Elon is always talking about making renewable energy available for the masses, then he goes and Apple's up the works... Very unfortunate.
This is a pretty expensive solution. I think it's likely that Musk feels like a robot arm that plugs a cord in for you is likely to be enormously more cost effective. This requires something probably like a 2-5k unit installed in every single parking spot. If you park an EV there that isn't charging, and isn't used by the grid, or you park a vehicle without the charging coupler, that infrastructure is wasted. Easy to vandalize too, unless they are embedded in concrete, and then you're looking at much higher costs to install and you're looking at high costs to repair road/parking lot surface. You could probably save a fuck load of money with an overhead electrified track system that had robotic arms suspended from it, which moved on it and gained power for their movement and for charging vehicles, with the ability to connect to multiple plugs as needed. Serve all the EVs in the lot, don't need to exclude non wireless EVs and since the system can fast charge, instead of dozens of KW you're talking hundreds of KW like the V3 super charger speeds, and because you're fast charging, you can have 1/10th the robot arms as you would have in floor wireless chargers, and this works for taxis in a que too. They drive under the track, if they pull away it decouples and quickly retracts to protect the arm, but if they creep along under it, the connector follows them, and again, much higher rates of charge, so that time spent in queue doesn't keep you going over the 8 hour day, it fully charges you in 10 minutes. The fact that this works at freeway speeds is pretty interesting, but the costs of having thousands of miles of this are enormous compared to "Oh shut the fuck up, just take a breather, walk around for 10 minutes, have a fucking coffee and be a human being." This seems really cool, but it also seems like the worst way to expand charging and electric vehicles to as many people as possible, and it's solving a marginal problem with non marginal costs. For a company with a fleet, it could pay off big over the long term. For a rich guy who likes expensive gadgets, it's a big winner, but for Elon, it probably looks like a dumb solution that solves a problem that smart solutions would also solve better.
@@markmcdougal1199 From Tesla strategic point of view I can understand it (not that I agree with their strategy). Having the capability to charge wireless will open the door for all kind of third party companies. Tesla likes to have full control over the entire infrastructure, super chargers, power wall and solar tiles and the car itself. Wireless charging all over the place by third parties, at shopping malls, restaurants etc does not fit into their strategy
Until about a year ago, I was the lead mechanical engineer in a group comprised primarily of electrical engineers, that partnered with WiTricity to help develop and integrate their technology into wireless vehicle charging products (power stations, ground "transmitter" coils, and vehicle "receiver" coils). Based on my personal experience and perspective, I believe that Mr. Gruzen has WAY oversold you on the current state of this technology-including its safety and efficiency. A traditional, induction stovetop and a resonant-induction-powered LED light puck are vastly different in both technology and scale from resonant-induction vehicle charging. For instance, your cat (wearing a tiny collar, with a metal buckle and a little silver bell, around it's neck) isn't likely to take up residence between the stovetop and a pot of chicken soup. But oh, how cozy that large, warm charge-pad (generating an extremely strong, invisible, inductive magnetic field) under the car would be. (Do the words "fried pussycat" sound familiar, Clark?) And keeping the LED lights on a low-energy device lit, when it's displaced an inch or two from its resonant-induction charge-pad is hardly a comparably equivalent demonstration of the "efficiencies" that can be achieved with similar displacement of a vehicle coil from "perfect" alignment with a ground coil-in all three axes, plus pitch and yaw (which is barely, if at all, achievable in a lab environment). When asked, in 2017, about any promising new battery technologies on the horizon, Elon Musk said, "Everything works on PowerPoint. ... That doesn't mean it works." The same goes here. You may want to go back and ask Mr. Gruzen to provide you with data and/or a live, real-world demonstration (i.e., not in a lab setting), to back up his claims. One thing, in particular, made me arch a brow. While Mr. Gruzen was explaining that wireless and wired (plug-in) vehicle charging efficiencies are equivalent (Spoiler Alert: They're not.), there was a video clip with the caption "Capable of wirelessly charging ALL VEHICLE TYPES with a SINGLE DESIGN" [based on ground clearance heights, from sports cars to SUVs]. ... Really? Where's the demo? Where's the data? What happens to the charging efficiency as you move from low clearance to high clearance (let alone variation in the other two axes, pitch, and yaw)? What are the heat losses? What prevents the extremely brittle and temperature-sensitive ferrite tiles in the vehicle coil from fracturing? Why does the SAE standard specify three different vehicle coil designs (Z1, Z2, and Z3), based on vehicle ground clearance ranges (two of which can be seen hanging on the wall, behind Mr. Gruzen, as he's talking)? And a hundred other unanswered questions. ... All pie in the sky. Don't get me wrong, the technology exists and is very interesting-and I was glad to make my own small contribution to its development. But it is nowhere near the state that it needs to be in, for even low-volume, mass consumption. And honestly, I'm skeptical that it can realistically ever get there (at least, not without a significant-as yet, unheard-of-technological breakthrough). Part of what keeps the technology alive is that it has the "whiz-bang" appeal that the masses love ever-so-much ("spooky action" at a distance) and that automaker CEOs absolutely drool over. So they allow themselves to overlook its practical flaws, and fail to explore better, alternative solutions. It is neither cheap nor easy to "transmit electricity" across an air gap of more than about an inch (even with "perfect" coil alignment), especially at the power levels and frequencies needed to charge a vehicle battery in a reasonable (i.e., consumer-acceptable) amount of time. Don't be fooled. Mr. Gruzen's job was not to give you honest answers to your questions (if that's what you were hoping for), it was to promote his company and the "whiz-bangyness" of their technology. In its current state, wireless vehicle charging is an expensive and inefficient luxury feature for the high-end consumer-vehicle market (Can you say "BMW" or "Porsche"?), which may also find a short-term niche market in the autonomous-vehicle industry-until a real wireless vehicle charging solution comes along. At that point, the current technology will become obsolete, and will end, not with a "whiz-bang," but a whimper.
We talked about this yeas ago, inductive roads, but no movement has happened on it, because of the loses! Now is the time to line all the roads and highways with solar and wind turbines, And to also get power from wave as well!
It seems like the best approach is a decentralised grid. Every house will have solar panels and their cars plus battery packs will stabilise the grid. A lot less energy will be required if we are not transmitting the energy over long distances like we currently do.
With inductive roadways the world grid could be implemented and an approach to significant efficiency and reduction in world temprature; absolutely necessary.
Hi Matt i kam just wondeing what is the max power transfer that can be done wirelessly. Also it would be noce to have an update on where the company is at. In Terms of their technology is it currenttly being deployed anywhere? And also how far along is the SAE J2954 standard in terms of consensus excellent video
Wow... Wireless Energy 😁 The Future is NOW... Mr. Tesla is smiling 😁 I can see tapping into the Earth's electromagnetic field with Synchronicity which is the mode of operation of Creation Energy which happens to be wireless... Wow! Here we go...
This would definitively be a game changer to entice more people to want to own EV's. And if they could create random miles of "charging lanes" on the highways just like they do for car pool lines, that could charge your car as you drive instead of having to stop to charge, that would also help increase EV's acceptance. Very cool stuff !!!
They only talking stupid fake stuff. They can't show it! Thank you for your input. We have in Switzerland the ETH and they also talking a lot of stupid stuff and people belive it like a blind sheep.
I remember when Captain Kirk picked up what looked like a flip phone and started talking to someone that was far away...stupid fake stuff gets made all the time.. keep doubting everything and you will continue to be amazed!
Great stuff Matt! Key phrase here "from grid to battery it's the same as wired chargers" Wireless is the future. Imagine a car made without an inverter, no charging port, solid state battery with the receiver coil built into the entire bottom of the pack assembly. 😁
@@GeoFry3 sorry about that, but if parking becomes an issue you could always install extra chargers to cover the entire driveway, turning it into one big maxi pad!🙂
Excellent video Matt. 2 questions that I think were still unanswered: 1) What are the losses or efficiency of the charging system compared to plugging in, and 2) What are the rates of charge they can supply?. I know they said 20kw at great than 60mph, but interested in what it could be when parked. Some of this might be confidential, but those are the 2 bug questions for me. Still though many applications like the taxi queue and autonomous charging depots make a lot of sense.
Your first question was answered a couple of times already: 90 - 93% efficiency, with the highest rated plug-in at 94%. Your second question, however, was not broached. Would be interested in knowing that answer myself.
Hi Matt. Yet another great and very informative video. Plzd to advise you that I have subscribed and of course given you the thumbs up. Looking fwd to viewing many more. Greetings from the UK John.
The wording behind this man's explanations feel less than fully useful for actually understanding the processes. Its more of an advertisement of its uses. Basically, 'This thing is proprietary, but it works super well, and it definitely works, oh, and did I say it was efficient?'
I'm skeptical of this. They haven't been able to even do it with laptops yet. I'd be glad to be proven wrong, but it seems like another fanciful promise of something they're always on the cusp of making.
Thank you for such an informative, high production video. This is awesome. EV ownership and driving becomes one of the simplest functions in our lives with this technology.
My question to snack charging is that going to affect the degradation of the battery by charging it too often or do you have a set percentage will it allow it to charge without causing degradation
I'm glad he gave us some info on how it charges. As a tech guy I was concerned about being able to charge the next gen of trucks and suv's. I love the idea of wireless charging. As I get closer and closer to wanting and deciding on a EV this helps break the small concern I have of range anxiety. Now making road trips won't be centered around planning out where to stop to charge.
This may be a little off the wall, but would it be possible to rig up a "jumper cable" so that a fully charged car could plug into another car and give it a little boost? I have never seen that discussed anywhere but I can see where that might be useful.
Heard about this technology seven /eight years ago and delighted to see it coming to fruition. For a crowded country like the U.K. where a lot of houses only have on street parking it’s the only way for E Vs to become main stream.
I love the fact that somewhere some one is working for the betterment of mankind! Thank god for creating these human beings who work day and night to create amazing solutions to the needs! 👏👏👏
Great video and very exciting tech. Can't wait for this to become common place. I did wonder about effect on people with pacemakers being in public locations. Sure it's easy to solve however using a car to charger 'handshake' before charge induction is started.
That's a lot of amps moving through an electromagnetic field. What happens if I have a 3 lb mini sledgehammer in my tool pouch and I step over the charging base?
I love wireless charging. It's exciting to see so many companies working on it with different technologies. 5W Resonant inductive charging -yanktech High Wattage Resonant inductive charging - WiTricity 2W IR base long line of sight - Wi-Charge Low wattage RF - Powercast, Engerous WattUp, Ossia, GuRu Free placement Qi - nomad base station pro, zens liberty I've been keeping an eye on them for years. Maybe some of them will finally start coming to market.
I would get this for my house for power outages/emergencies. How many days can you run your house during a power outage with just a gen 1 leaf? Wow just that though alone makes this a must have!
Honestly I've been talking about this for many years, super cool to see this coming. Most likely autonomous vehicles are gonna line up the first one leaves the last one goes back in like to be charged and so on. Of course if all major highways were electrified that would be amazing but the cost of the infrastructure would be huge
It appears to be a similar solution to that placed as an experiment, in a South Korea amusement park, several years ago, for its buses. Could this be deployed on the inside lane, the slow lane, of a motorway (freeway), to address one of the problems of EV takeup, that of 'range anxiety'?
I wonder will we get special toll roads that run alongside highways for a few miles just for charging on the move? I suspect there would be resistance from service station owners.
Thanks for making this video Matt. Wireless charging would make a BEV so much easier for me and many others who don't have access to an indoor garage space. I'd be happy to pay a few thousand bucks for this.
Will people with heart pacemakers be affected detrimentally by either form of charging? Can I sit in the Tesla while it's charging and my pacemaker won't be affected?
Matt, this is one of the most exciting topics that I have seen covered recently. Well done!
Thanks!

Wireless charging is the obvious choice in view of autonomous driving.
I hope that all car producers including Tesla will adopt this with the same standard
Yeah....Elon is not about to lock himself into some ice car company standard...
It is not the "obvious choice" ... Tesla has not adopted it because it does not work, is not reliable, and is not cost effective. I wanted to believe it too, then I did my research. I carefully studied the schematics, hired an electrical engineer, and went into the field to try to find even 1 successful installation. In the end, the conclusion was "obvious" ... charging a tooth brush or a phone is one thing ... charging a car or bus wirelessly is another. In my opinion ... it is a fraud. I own 2 electric cars ...

Charging at 60 mph! Now that’s what I’m talking about. Great content, Matt. Subscribed to the pod and looking forward to giving it a listen.
Thank you Matt Ferrell for this video, at the beginning I though this was just hyped technology that wasn't ready yet nor would ever will, then I paused I searched the J295 standard, searched the magnetive resonance power transfer and now I am impressed that wireless charging is practically as effective as plug charging.
Thanks to you I learned something today.
Thanks for a nice look towards the future of wireless charging for EVs. One thing I missed was a discussion with the Witricity representative on charging effects. On their web-page it states effects of 3, 7 and 11 kW, while the guy mentioned 20 kW in the dynamic charging scenario. With super-chargers capable of 150kW and even 250kW, this would be a relevant topic to discuss. Especially in the context of dynamic charging situations, where you would have access to charging during shorter idle times or queueing scenarios and in those situations effect is highly relevant.
Alex did touch on that topic when we were talking. This is slower than fast chargers, so it makes the most sense in stationary charging locations like parking lots, garages, etc. Alex told me that we'd still need to rely on plugging in at fast chargers on longer road trips (at least for now). Unless we start adding these embedded wireless chargers into highways to charge as you move. At that point you'd never have to stop and charge ... ever. But the cost of adding them to roadways would be cost prohibitive on a large scale.
Low speeds make sense if you are doing it 24/7, and remember supercharging is limited to about 20MW by Tesla, also as you increase the power you will produce more EM radiation and will require more shielding in the car..
250KW of Magnetic Field ! :O Now I know where my keys are !!!!
@@UndecidedMF It would be interesting to know whether there are hard physical limits to this technology and to how much power it could scale up to.
It might also be a viable option for long-haul-trucks in the parking lots where the drivers sleep if the power can be scaled up to get a full charge overnight.
You don't need that much energy to maintain your speed. It's acceleration that consumes energy.
I would like to see charging areas on the highway. Maybe a 3 mile 20kw strip every 5 miles or so. That won't fully recharge your car while driving but it would extend your range quite significantly.
Matt your no nonsense, pure facts, no silly background music style is very much appreciated. Carry on brother!
Put these into the road of busy intersections! Never was waiting for the green light so enjoyable for a driver. :D
Ha! Great point. There may not be a need to electrify all roadways, but you could electrify key locations for dynamic charging.
@@UndecidedMF Did he talk about creating a standard for identifying the vehicle (owner) to bill for the charge? Like the Tesla Supercharger network the communication down the cable identifies the VIN and the owner. There needs to be a standard like this to make adoption straightforward. Love the video by the way.

Wireless charging for EV is gonna be the most revolutionary thing of this century, if we can do it. It basically eliminates all the cons of EV and possibly ends the ICE vehicle industry as a whole. Great topic and very informative video Matt...loved it!
Thank you for covering the efficiency angle. That was honestly my biggest question about this solution. This is an amazing development to allow much easier implementation and deployment of charging services. I do wonder if it can support super-charging speed though, or if it will require a parking lot to have these pads in a majority of spaces within the next 30 years or so.

Nice job, Matt. Good questions, excellent instructional graphics, simple, informative interview, hitting the salient points. You earned a thumbs up. Of course, there's always room for improvement :) More specificity of price (adding cherry wheels can cost between $800.00 and 10k, same with sound system.) Also, more info about real world logistics - what would be entailed in retrofitting my car: Still need 220 out to my driveway? Pad security (outdoor) if I don't want to rip up the concrete in my driveway, cost for car stuff, pad stuff, additional electrical equipment, need electrician, how does the foot of snow on my driveway effect it; nut's and bolts stuff. Of course, this could prolly be a whole nuther vidio :). But still, good job Matt.
Thanks for the feedback, Mark. We did dance around some of that, but not explicitly. There were sections I cut for time that might have helped. In short, the pads are very, very safe outside. They work under water, snow, etc. I wasn't able to get a clear price, but it sounds like we'd be talking a few thousand dollars right now (prices dropping over time). Retrofitting is a no-go according to Alex ... at least DIY retrofitting. A company, like Tesla, BMW, etc. offering their own retrofit would be another story, but I doubt that's something that will happen. This is most likely only going to show up on new cars.
for security you would just bolt it down.. Home use wouldn't bother counter sinking into the driveway/garage floor

one reason ... CANCER
Real Truth eh?
You get cancer with all the pollutants in the air, everything from polluting vehicles to pesticides to various factory chemicals...
Pollutants in what we drink, run off of all such chemicals, scientifically created artificial chemicals created to sweeten or color our beverages, pollutants in our food, again scientifically created artificial chemicals to supposedly improve taste or dye the food to make it more appealing or create bug resistant crops, or lengthen shelf life of food and drinks, pretty much to create chemicals to make the best type of cancers to create a cure for to sell to the market.
Don't believe me read the artificial chemicals in the ingredients of food or beverages and see what types of cancer they bring about in our bodies, or smell if something is not natural and see pesticide ingredients, or what polluting vehicles do to us, or various aresol fumes and such... See what all the scientifically created artificial unnatural unnecessary poisons do to anything of nature, that is against all things natural.

@@Barzen873 If they didn't state the number, it's because it's not very good...
Loved this video and the idea! One of my gripes with the many ICE vehicles I've owned over the years is that the stupid gas/diesel fill is on one side or the other. WHY NOT BOTH? So it'll take some slight adjustments to the design and add a little to the cost of the vehicle, but come on. So why am I mentioning this? Because the same can be true of having to plug in your electric vehicle at home. Which side of the vehicle do you mount the wall charger? Which side of a multi-car garage do you park on? For those cars that have the charge port on the front or rear, same type of issue if you vary pulling forward into your garage or back in. With this wireless charging (and if the receiving unit on the car is centered) it won't matter how you like to park; it'll just work. And the efficiency of wireless charging is no longer an issue. I love it!

Elon needs to let us retrofit our Model 3's with this technology. What's more, the idea of my car battery essentially becoming a power wall for my house is amazing.
My question is, how much does this impact battery lifetime...
Currently I only charge every three or four days as I only need arounmd 30 to 40 miles a day. Now if charge those 30 miles back up every day would this be a bigger impact to lifetime compared to charging 150 miles every few days.

Definitely the way way forward. With that level of efficiency, low cost and lack of hassle. Almost a no brainer.
This is not "low cost" ... even the video does not claim it to be "low cost". It is extremely cost prohibitive ... if it works at all ... and they have not proven in the field it even works.

That's part of why I asked him at one point if it could be retrofit. I was ready to throw money at it him for it.
I'm more excited about about the other side of the idea that you can also reverse the polarity or the components and contribute electricity to the power grid. Imagine driving over a coil on the highway where at the toll booth would give you a reduction for contributing to the power grid.
Love this idea, the options for this technology is going to fun watching evolve.
And it's sample renewable and efficient...
Tx for bringing this to us, Matt! 11 kW charging speed is plenty for any overnight charging, which is 90% of the charging time your EV will ever do. So this wireless charging variant that leaves some room for positioning error, is THE solution for all of our city folk that doesn't have access to off-street parking, opening up EV driving to the wide masses. Puzzled still why Elon doesn't believe in it - is there any first principles reason NOT to support this?
It's weird that they are deploying everywhere and they don't have the module plugged into a car to demo it.
Matt , great review and reporting, well done . This is a game changer . The wireless charging players spent the last 10y to lobby and build a global standard for all and any cars, who needs the equivalent of a plug format war. The simplicity, efficiency , compatibility are key factors for EV to succeed. This has enormous potential. 👍 to Your Question, I’m definitely interested. Time for SurveyMonkey?
How exciting. Some parts of the future look absolutely amazing. Some parts.....
not only do you not have to remember to plug in, the lack of standardization of various plugs across different brands will no longer be an issue as well. the vehicle to grid aspect is truly very exciting as well, it renders a vehicle as an energy investment that double-duties as a tool for transportation when necessary (with shelter in place, who knows, maybe ppl would've adjusted their lifestyles to have become less car dependent whenever it is when this all ends)
7:30 Up to 11 kW? That charging speed almost matches what's in my garage but a Supercharger can do up to 250 kW. So, not quite there yet.
Most cars are charged at home, or overnight, speed isn’t everything everyday.
@@Muppetkeeper This video is about charging in parking lots.
As for charging in garages, like I said, the wired charger in my garage does 11-12 kW so the current wireless version adds very little other than some strong electromagnetic disturbances that I can probably live without.
Arth Denton I think it does add something for people without a garage or a driveway, being able to charge in the street without trailing cables is important, and this sort of charging does not need 100kw.
@@Muppetkeeper You may have something here. Indeed, wireless charging while parking could make life easier for city people.
Hopefully, they can design faster wireless chargers but I can see how it may not be easy because of the strong electromagnetic disturbance this would generate.
Arth Denton Just don’t get a heart pacemaker and you’ll be ok, the EM field does not stray far from the plate.
fully 60% of the cost of a good solar system is a battery pack. having your car supplement your solar storage would be simply AWESOME. best of both worlds.
I would recommend that you actually look into the physics of this. I worry about the magnitude of magnetic fields these will need to be efficient and what the side effect of these fields will be. What are the EM emmissions, how does it affect any magnetic media in close vicinity ?
Yeah I've heard it's actually possible to wirelessly charge pretty efficiently... if that was the case, I'd love this in my garage although it's not really necessary. But for public areas? Aw yeah!
Did you get a new camera? Looks great.
So magnetic resonance is the magic bullet that achieves nearly perfectly efficient transmission of energy between two coils of wire irrespective of alignment or distance? It's not the first time MIT have publicly backed snake oil.
Wow, this is great. I remember hearing about WiTricity in Apple rumors and hoping that Apple would implement it for powering wireless keyboards, mice, headphones, etc. It would have been great for the iPhone (or any phone) if it could be small enough.
Hopefully it could still happen for everything needing power.
....a great piece... this IS the future and he is going to be a rich man!
Here's a suggestion for a future video: try to go a month without charging at home or at work. I've recently moved out from my house that's being remodeled and the apartment doesn't have any charging. The local Tesla Supercharger for my Model 3 is always too busy, so I've been pulling my hair out trying to keep my car charged! But I've learnt a lot more about options such as the PlugShare app that can help.
Good call out.
To use an American expression. It's a no brainer. Great video too. Thank you.

Awesome video Matt, imagine a new multi level parking garage with these pads at every spot, an EV hotel!
There is a critical question that I wish was asked: how far can the plates on the ground vs in the car be? Will something like a raised Cybertruck be able to charge as fast as a plugged in charger with no efficiency loss? Also what is the charging speed??????
this is indeed a valid question, one which I also want answered... like how far is the range, and how much does it "lose" efficiency by range?
Is it same efficiency all ranges, then at a certain range doesn't work at all?
Or lose more and more efficiency the further away, but still work, until too far away simply not efficient any more?
Really interesting video...I’ll be watching this company. Thanks for sharing this and so many other great ideas, companies, thoughts, etc.
Can you imagine what that would do on a long road trip if you could pull on to a side road and charge your car without stopping.
Very exciting. Thanks for the show.
I wish them success in bringing the product out.
Seems promising to me. Thanks Matt! I may have missed it, but I don't think I heard any mention of Tesla in the video. I'm sure you must have asked the question...

@@buddy1155 That sucks.... Elon is always talking about making renewable energy available for the masses, then he goes and Apple's up the works... Very unfortunate.
This is a pretty expensive solution. I think it's likely that Musk feels like a robot arm that plugs a cord in for you is likely to be enormously more cost effective.
This requires something probably like a 2-5k unit installed in every single parking spot. If you park an EV there that isn't charging, and isn't used by the grid, or you park a vehicle without the charging coupler, that infrastructure is wasted. Easy to vandalize too, unless they are embedded in concrete, and then you're looking at much higher costs to install and you're looking at high costs to repair road/parking lot surface.
You could probably save a fuck load of money with an overhead electrified track system that had robotic arms suspended from it, which moved on it and gained power for their movement and for charging vehicles, with the ability to connect to multiple plugs as needed. Serve all the EVs in the lot, don't need to exclude non wireless EVs and since the system can fast charge, instead of dozens of KW you're talking hundreds of KW like the V3 super charger speeds, and because you're fast charging, you can have 1/10th the robot arms as you would have in floor wireless chargers, and this works for taxis in a que too. They drive under the track, if they pull away it decouples and quickly retracts to protect the arm, but if they creep along under it, the connector follows them, and again, much higher rates of charge, so that time spent in queue doesn't keep you going over the 8 hour day, it fully charges you in 10 minutes.
The fact that this works at freeway speeds is pretty interesting, but the costs of having thousands of miles of this are enormous compared to "Oh shut the fuck up, just take a breather, walk around for 10 minutes, have a fucking coffee and be a human being."
This seems really cool, but it also seems like the worst way to expand charging and electric vehicles to as many people as possible, and it's solving a marginal problem with non marginal costs. For a company with a fleet, it could pay off big over the long term. For a rich guy who likes expensive gadgets, it's a big winner, but for Elon, it probably looks like a dumb solution that solves a problem that smart solutions would also solve better.
@@markmcdougal1199 From Tesla strategic point of view I can understand it (not that I agree with their strategy). Having the capability to charge wireless will open the door for all kind of third party companies. Tesla likes to have full control over the entire infrastructure, super chargers, power wall and solar tiles and the car itself. Wireless charging all over the place by third parties, at shopping malls, restaurants etc does not fit into their strategy
Until about a year ago, I was the lead mechanical engineer in a group comprised primarily of electrical engineers, that partnered with WiTricity to help develop and integrate their technology into wireless vehicle charging products (power stations, ground "transmitter" coils, and vehicle "receiver" coils). Based on my personal experience and perspective, I believe that Mr. Gruzen has WAY oversold you on the current state of this technology-including its safety and efficiency.
A traditional, induction stovetop and a resonant-induction-powered LED light puck are vastly different in both technology and scale from resonant-induction vehicle charging. For instance, your cat (wearing a tiny collar, with a metal buckle and a little silver bell, around it's neck) isn't likely to take up residence between the stovetop and a pot of chicken soup. But oh, how cozy that large, warm charge-pad (generating an extremely strong, invisible, inductive magnetic field) under the car would be. (Do the words "fried pussycat" sound familiar, Clark?) And keeping the LED lights on a low-energy device lit, when it's displaced an inch or two from its resonant-induction charge-pad is hardly a comparably equivalent demonstration of the "efficiencies" that can be achieved with similar displacement of a vehicle coil from "perfect" alignment with a ground coil-in all three axes, plus pitch and yaw (which is barely, if at all, achievable in a lab environment).
When asked, in 2017, about any promising new battery technologies on the horizon, Elon Musk said, "Everything works on PowerPoint. ... That doesn't mean it works."
The same goes here. You may want to go back and ask Mr. Gruzen to provide you with data and/or a live, real-world demonstration (i.e., not in a lab setting), to back up his claims.
One thing, in particular, made me arch a brow. While Mr. Gruzen was explaining that wireless and wired (plug-in) vehicle charging efficiencies are equivalent (Spoiler Alert: They're not.), there was a video clip with the caption "Capable of wirelessly charging ALL VEHICLE TYPES with a SINGLE DESIGN" [based on ground clearance heights, from sports cars to SUVs]. ... Really? Where's the demo? Where's the data? What happens to the charging efficiency as you move from low clearance to high clearance (let alone variation in the other two axes, pitch, and yaw)? What are the heat losses? What prevents the extremely brittle and temperature-sensitive ferrite tiles in the vehicle coil from fracturing? Why does the SAE standard specify three different vehicle coil designs (Z1, Z2, and Z3), based on vehicle ground clearance ranges (two of which can be seen hanging on the wall, behind Mr. Gruzen, as he's talking)? And a hundred other unanswered questions. ... All pie in the sky.
Don't get me wrong, the technology exists and is very interesting-and I was glad to make my own small contribution to its development. But it is nowhere near the state that it needs to be in, for even low-volume, mass consumption. And honestly, I'm skeptical that it can realistically ever get there (at least, not without a significant-as yet, unheard-of-technological breakthrough).
Part of what keeps the technology alive is that it has the "whiz-bang" appeal that the masses love ever-so-much ("spooky action" at a distance) and that automaker CEOs absolutely drool over. So they allow themselves to overlook its practical flaws, and fail to explore better, alternative solutions. It is neither cheap nor easy to "transmit electricity" across an air gap of more than about an inch (even with "perfect" coil alignment), especially at the power levels and frequencies needed to charge a vehicle battery in a reasonable (i.e., consumer-acceptable) amount of time.
Don't be fooled. Mr. Gruzen's job was not to give you honest answers to your questions (if that's what you were hoping for), it was to promote his company and the "whiz-bangyness" of their technology. In its current state, wireless vehicle charging is an expensive and inefficient luxury feature for the high-end consumer-vehicle market (Can you say "BMW" or "Porsche"?), which may also find a short-term niche market in the autonomous-vehicle industry-until a real wireless vehicle charging solution comes along. At that point, the current technology will become obsolete, and will end, not with a "whiz-bang," but a whimper.
We talked about this yeas ago, inductive roads, but no movement has happened on it, because of the loses! Now is the time to line all the roads and highways with solar and wind turbines, And to also get power from wave as well!
Not sure if serious.
It seems like the best approach is a decentralised grid. Every house will have solar panels and their cars plus battery packs will stabilise the grid. A lot less energy will be required if we are not transmitting the energy over long distances like we currently do.
Don't think this resonance idea will work with moving objects. Probably needs to be stationary.
@@gregcollins3404 the video just literally said that it does work with moving objects. They even used a car going at over 100km/h and it charged.
With inductive roadways the world grid could be implemented and an approach to significant efficiency and reduction in world temprature; absolutely necessary.
Hi Matt i kam just wondeing what is the max power transfer that can be done wirelessly. Also it would be noce to have an update on where the company is at. In Terms of their technology is it currenttly being deployed anywhere? And also how far along is the SAE J2954 standard in terms of consensus excellent video
Wow... Wireless Energy 😁
The Future is NOW... Mr. Tesla is smiling 😁 I can see tapping into the Earth's electromagnetic field with Synchronicity which is the mode of operation of Creation Energy which happens to be wireless... Wow! Here we go...
No we wont. The magnetic field cant be used to generate any significant power.
This would definitively be a game changer to entice more people to want to own EV's.
And if they could create random miles of "charging lanes" on the highways just like they do for car pool lines, that could charge your car as you drive instead of having to stop to charge, that would also help increase EV's acceptance. Very cool stuff !!!
thought this would be just another chic, untenable medium for electrification, but it will probably be a game changer
@7:50 - Why not just call it WiPi? it has the familiar sound of WiFi but could stand for (Wireless Power Interface).
THEN SHOW US! show us input/output power on a real car please! I really want to believe this :)
They only talking stupid fake stuff.
They can't show it!
Thank you for your input.
We have in Switzerland the ETH and they also talking a lot of stupid stuff and people belive it like a blind sheep.
Correct ... THEN SHOW US ! WiTricity cannot prove it works in the field. In my opinion this is fraud.
I remember when Captain Kirk picked up what looked like a flip phone and started talking to someone that was far away...stupid fake stuff gets made all the time.. keep doubting everything and you will continue to be amazed!
@@TheRealJayGutta Big difference between technology and physics!
@@rymannphilippe Not true. I have a blind sheep, but she doesn't believe anything I tell her.
Great stuff Matt! Key phrase here "from grid to battery it's the same as wired chargers"
Wireless is the future. Imagine a car made without an inverter, no charging port, solid state battery with the receiver coil built into the entire bottom of the pack assembly. 😁
Exciting for sure!!!
Very cool, finally my wife will not leave the car on "E" again.
Yes, as long as she parks on her pad!
@@jamespaul2587 women and their pads
@@jamespaul2587 well damn you burst my bubble
@@GeoFry3 sorry about that, but if parking becomes an issue you could always install extra chargers to cover the entire driveway, turning it into one big maxi pad!🙂
Excellent video Matt. 2 questions that I think were still unanswered: 1) What are the losses or efficiency of the charging system compared to plugging in, and 2) What are the rates of charge they can supply?. I know they said 20kw at great than 60mph, but interested in what it could be when parked. Some of this might be confidential, but those are the 2 bug questions for me. Still though many applications like the taxi queue and autonomous charging depots make a lot of sense.
Your first question was answered a couple of times already: 90 - 93% efficiency, with the highest rated plug-in at 94%.
Your second question, however, was not broached. Would be interested in knowing that answer myself.
E P I C interview! Love it ! I want one Elon give us what we need ! Thanks for this !
👍 Thanks so much!
Fascinating video. So many possible applications. Hopefully there aren't too many issues (cost) that prevent it from happening. Thanks for sharing.
First comment... Pow!
Damn you.
@@DeltaV3 Mwahahahahha (evil laugh)
Is there a park and charge billing dialogue within the standard as well or will there still be a card/app be required to use it in public settings?

Hi Matt. Yet another great and very informative video.
Plzd to advise you that I have subscribed and of course given you the thumbs up. Looking fwd to viewing many more.
Greetings from the UK
John.
The wording behind this man's explanations feel less than fully useful for actually understanding the processes. Its more of an advertisement of its uses. Basically, 'This thing is proprietary, but it works super well, and it definitely works, oh, and did I say it was efficient?'
Seoul has had a bus lane with inductive charging for some years, and Genoa has a different technology for 3-phase bus re-charging since the 1960s.
I'm skeptical of this. They haven't been able to even do it with laptops yet. I'd be glad to be proven wrong, but it seems like another fanciful promise of something they're always on the cusp of making.
Thank you for such an informative, high production video. This is awesome. EV ownership and driving becomes one of the simplest functions in our lives with this technology.
My question to snack charging is that going to affect the degradation of the battery by charging it too often or do you have a set percentage will it allow it to charge without causing degradation
I'm glad he gave us some info on how it charges. As a tech guy I was concerned about being able to charge the next gen of trucks and suv's. I love the idea of wireless charging. As I get closer and closer to wanting and deciding on a EV this helps break the small concern I have of range anxiety. Now making road trips won't be centered around planning out where to stop to charge.
Awesome work. Very high quality video. Well explained and visually good to watch. I like the calm excitement of it as well.
Thanks!
This may be a little off the wall, but would it be possible to rig up a "jumper cable" so that a fully charged car could plug into another car and give it a little boost? I have never seen that discussed anywhere but I can see where that might be useful.
Heard about this technology seven /eight years ago and delighted to see it coming to fruition. For a crowded country like the U.K. where a lot of houses only have on street parking it’s the only way for E Vs to become main stream.
Matt, how do they identify each car? For public use, do they envision that there be a standard to identify each users credit account?
I love the fact that somewhere some one is working for the betterment of mankind! Thank god for creating these human beings who work day and night to create amazing solutions to the needs! 👏👏👏
Can I put my head between the 2 charging plates? On a more serious note, what about EV shielding? I do not want my head picking up any EM radiation.
Great video and very exciting tech. Can't wait for this to become common place. I did wonder about effect on people with pacemakers being in public locations. Sure it's easy to solve however using a car to charger 'handshake' before charge induction is started.
That's a lot of amps moving through an electromagnetic field. What happens if I have a 3 lb mini sledgehammer in my tool pouch and I step over the charging base?
I love wireless charging. It's exciting to see so many companies working on it with different technologies.
5W Resonant inductive charging -yanktech
High Wattage Resonant inductive charging - WiTricity
2W IR base long line of sight - Wi-Charge
Low wattage RF - Powercast, Engerous WattUp, Ossia, GuRu
Free placement Qi - nomad base station pro, zens liberty
I've been keeping an eye on them for years. Maybe some of them will finally start coming to market.
I want to see the math that would show the efficiency. RF coupling is not new so what is?
I would get this for my house for power outages/emergencies. How many days can you run your house during a power outage with just a gen 1 leaf? Wow just that though alone makes this a must have!
What is the efficiency between the car transformer just before the lithium battery?
Honestly I've been talking about this for many years, super cool to see this coming. Most likely autonomous vehicles are gonna line up the first one leaves the last one goes back in like to be charged and so on. Of course if all major highways were electrified that would be amazing but the cost of the infrastructure would be huge
It appears to be a similar solution to that placed as an experiment, in a South Korea amusement park, several years ago, for its buses.
Could this be deployed on the inside lane, the slow lane, of a motorway (freeway), to address one of the problems of EV takeup, that of 'range anxiety'?
I wonder will we get special toll roads that run alongside highways for a few miles just for charging on the move?
I suspect there would be resistance from service station owners.
Thanks for making this video Matt. Wireless charging would make a BEV so much easier for me and many others who don't have access to an indoor garage space. I'd be happy to pay a few thousand bucks for this.
What's the maximum output when parked? They said 20kw when rolling along their track. Model 3 is doing 250kw now.
Jesse Connell the Wificity spokesman above said they have already implemented 250kW charging on buses..
This is going to be the next big tech channel. Great job!
Will people with heart pacemakers be affected detrimentally by either form of charging? Can I sit in the Tesla while it's charging and my pacemaker won't be affected?
‘Mapping ALL the car parks ACROSS China..’
Well that shouldn’t take long! 😆
Great video of course, joking aside. Loving the channel.
