Evatran, as the only company to introduce wireless charging kits for the Nissan LEAF, Chevrolet Volt and Cadillac ELR(and soon the Tesla Model S and BMW I products) in the US and Canada, this year is expanding to Europe.

This year Evatran will supply over 20 PLUGLESS systems for an 18-month trial project called WiCh across Sweden.

“Today, Evatran and Swedish officials announced they are prepared to install over twenty PLUGLESS wireless Electric Vehicle (“EV”) charging systems in locations across Stockholm, Uppsala, and Gothenburg. The research program, termed WiCh (Wireless Charging of Electric Vehicles), aims to test the effect of wireless charging on the usage of electric vehicles in real life conditions. Evatran, the leader in wireless EV charging, has been installing its PLUGLESS systems with individual drivers and fleets across the US and Canada for the past 14 months. This will be the first large-scale demonstration of its technology outside North America.”

PLUGLESS has 3.3 kW of power and in Europe the project will probably focus solely on Nissan LEAFs.

Stefan Pettersson, research manager at Viktoria Swedish ICT, commented on the importance of wireless EV charging:

“Our research indicates that wireless charging can be an important piece of the puzzle in getting more people to drive on electricity instead of less environmentally friendly options. We see this demonstration project as a research area where we have the opportunity to test the technology with real users.”

Rebecca Hough, Evatran CEO and Co-Founder said:

“We’re excited to be part of this first-of-its-kind trial in Sweden. While we have focused on rolling out our technology to customers in North America, it is important to spread the word about the significant impact that wireless charging can have on overall EV adoption and usage across the world.”

I am surprised they have not developed this for Tesla’s. Spending $2K for a Leaf is a large % of the cost of the car, spending $2K for a Tesla is a much smaller % and the Tesla owners in general would probably buy more of these.

It’s 3.3kW charging. You know, the one Volt owners complain about. Tesla owners get a 14-50 installed and charge at 9.6kW, or an HPWC and charge at 19.2kW. More in Europe.

EV owners understand that plugging in is no big deal. Wireless is an expensive luxury and so 3.3kW doesn’t cut it.. When all cars have basic self-driving capability, wireless will have more benefit, unless Tesla can master its snake.

If 3.3kW is sufficient for you today, like the vast majority of us, why on earth would it not be in 5 or 10 years from now? Are EVs from tommorow going to need more power to do the same job they are doing today???
You said ”Wireless is an expensive luxury and so 3.3kW doesn’t cut it..”, It does cut it for most of us! I don’t have to tell you most of the charging is done at night, right? Of course it’s expensive compared to a plug, so are leather seats compared to fabric but i’d be willing to bet you have leather….;)

It would take too long for a big battery to recharge at 3.3 kW.

I charge my 2 ev’s when I come home from work. And many other People do as well. In Norway the price for electricity is not that expensive

Stay tuned, a Tesla ready system will soon be available…

3.3kW is “a bit” outdated. You should never buy any charging equipment that can just handle your current needs. These things should be 6.6kW at least.
Is there a standard for these chargers? If not, you would just save the overnight plug-in/unplug. I would never spend that much for that little convenience.

3,3 kW is enough if you have a larger battery pack. With my tesla 3,3 kW is enough, but I would like a higher chargespeed on my nissan leaf (220V, 32A)

I’d love to see independent reviews of this device and measure the inductive charging loss. Plus, as others have mentioned, it really needs to be 6 kW at least, preferably 10 kW. Again, we’d have to know the inductive losses. A common robotic plug system could be more interesting at this point.

And on page 7, this”– Secondary coil output was unable to be measured due to sealed
vehicle-side enclosure”
Not sure, but It seems that conclusion can’t be made for total efficiency of the system.

It does not necessarily need to be more than 3,3 kW. The larger batterypack, the less need for high chargespeed. These small batterypacks that currently exit will soon be replaced by higher density packs, and then, unless you drive taxi, 3,3 kW is enough. With smaller packs, like my nissan leaf, higher chargespeed would be preferred. But my tesla works fine with approx 3kw

I still don’t understand why they’re developing this instead of robotic charging connectors.

It could be as simple as driving over a pad, then a wireless link triggers a cover under the car to open, and the charging connectors rise up on a simple scissor jack mechanism until contact is made.

Wireless significantly reduces efficiency. A self-connecting charge pad (with a small accessory charge port added to the underside of the car) seems a far better choice to me.

Are you for real, Michael?
You are saying that you would take a very complex robotic system with a lot of MECHANICAL moving parts to replace a simple, tried and true wireless system witch is just an open transformer after all.
And that complex robotic system would be much much cheaper than $2000 box, right? …right???
I suppose you would like to replace your wireless tv remote with a robotic arm that would stretch from your remote to change the channels? lol.

The complexity of the mechanical device is the easy part. The deal breaker is the standardization of the connector still exists AND you now need communications standards as well.
I have to admit that I still like the idea of the mechanical arm though I agree totally that wireless will win out in the end for multiple reasons.

I have an article being posted this week on autonomous parking/charging. You would think that wireless would be the no brainer answer, but you might be surprised to see the manufacturer releasing the first with a robotic arm. Interesting times…

I’m for real. Scissor jacks aren’t even a little bit complex, I don’t know where you’re getting that objection from.

I’m willing to bet that Tesla announces a far more complex robotic arm charger for sale before the end of next year.

Keep your snotty comments, as my TV remote control doesn’t POWER my television for hours on end, it only controls it a few seconds a day.

The mind boggles!

If wireless charge has 88% efficiency, I can easily pay the extra cost compared to regular charge. For normal driving, those few extra $ can be payed if I don’t need to spend any time connecting my car to the grid.

Convenience sells, no doubt about it. Having been a user for 18 months now, i can assure you i would not go back to the plug, ever. It has the same effect on you as going from ice to electric, minus the gaz bill. There is no monetary savings, in fact, it will cost you 10 to 12% more to charge your vehicule but the benefit is convenience. That 12%, in my part of the world, Montreal, represents about $30 more a year or about a dime a day. I agree that 3.3kW could be bumped up to 6.6kW for the minority that needs it and it soon will be. It will be available for Teslas, among other brands, very soon also. So stay tuned. As a side note, a 3.3kW is enough for my needs today and very likely will be tommoŕow as i seldom drain my Volt battery from day to day. But when the time comes for my next car, a Tesla for sure, the 6.6kW will be available soon enough from the last chat i had with the company. For those of you who see no needs for such a system, be it because of the… Read more »

Some old figures that used to be bounced around were that it costs about 10 cents a mile to fuel a standard ICE but only about 2 cents/mile with electrics.

The math is simple. If you drive 15,000 miles per year in an Ice, it costs you $1500 bucks a year to fill up at .10 cents/mile. To cover the same mileage in an EV only costs $300 dollars.

Inductive chargers running at 90% efficiency add just 10 per cent to your $300 per year fuel bill. That works out to be 30 extra dollars, or just $330 a year total, This is a nominal amount and still light years ahead of your ICE fuel bill.

Small price for a huge convenience.

No more fumbling with electric cords or gas pump hoses ever again.

But i would miss answering all the questions from passerbys when i’m plugging in or unplugging at a public charge station! Most are amazed when i tell them that box on the pole is for charging an electric car and its free. Most people still do not realize there are highway capable electric cars available from a handful of manufacturers. My local newspaper wrote an article about the upcoming Tesla Model X and never mentioned it was electric. I wonder if there are people that just think its a really nice looking car and don’t realize its electric. I’ll continue to plug in as a badge of honor. I enjoy all the conversations it starts. People already ice charging stations with big signs on the spots. Can you imagine how badly they will be iced when there is no visible station. only a sign?

When i first got my Volt, Most people walking on the street would not notice my plug, but when Plugless was installed , the majority wuould actually notice the pad laying underneath the back of the car and the first time just stand there trying to understand what they were watching exactly and then see the Control panel on the wall facing the car. Then they get it!
Funny as hell:)

I’m hopping for a Universal Wireless System with incar guidance system and imbedded inground induction pad. No more cables laying on the ground getting dirty and open to vandals. All you see is a donut imbedded in the ground, no control panels or outside guidance system.
One central computer sending the right amount of power to any idividual car detected. So say one Powerhouse for ten, twenty different pads. Seriously reducing the cost of adapting a big parking lot.
Clean, simple and effective.

Would be a great addition to Valet parking. Just have for each spot so you could park and charge any EV in any spot! Especially once they can be embedded in the lot. Same with workplace charging where 3.3 kW would probably be just about right.

Never. Never ever, not in a million years would I use that crap. If I bought a car where it was standard, I’d tear it out. Wireless charging is hugely wasteful, expensive, and heavy. The only thing it really accomplishes is to make EVs worse. More expensive to buy, more expensive to operate, and reduces range.

It’s also bad for the environment.

It’s never “never”.

10% worse for the environment than a plug EV which is 1000% better for the environment is a good trade-off to get people to go EV.

Would you wirelessly charge your iPhone if it came enabled? Say, Apple waterproofed it and that’s the only way. I’m thinking “yes”.

I’ll bet the old crap will go away eventually. Not never.
