A few days ago we brought you the news that GM will begin offering in-car wireless charging mats for mobile phones as an option from Q3 2012. These devices, that are making big waves at trade shows both in the U.S. and around the world, do away with the pesky cords and bulky adapters of old, replacing them with two conductive metal plates (i.e. one on the back of your phone and one in your car).
So imagine if you could charge your electric car this way. It should be simple, right? You’d just need to upscale it to suit charging a bigger battery. Well, at the 2011 CES technology trade show in Las Vegas, Fulton Innovation showed such a gadget by wirelessly charging the be-all and end-all of electric vehicles: the Tesla Roadster.
The eCoupled Powerspot, as it is called, works on the same principles as its smaller cousins and can even provide you with charging updates through a smart phone app. Do you want to keep track of how much it costs to recharger your electric car? The app can do that too.
There’s even a video, though admittedly it’s not very interesting. No electrical arching or unearthly humming noise here, I’m afraid; just a silent, practical vision for the future. You can check out the video for yourself, if you’re so inclined. There’s no indication of when this technology will be available, though I suspect we will be seeing it within the next five years or so.
It has, after all, been used by Hino to recharge electric busses for at least the past two years. It’s not so much a matter of if but when, and whether it can be made cost effective. One thing is for sure, the future for electric vehicles just got a little brighter.
