Electric Roadway Charges Electric Vehicles

Previously on CleanTechnica, Breath on the Wind covered the fascinating and exciting potential of wireless electric vehicle charging. In particular, he examined the wireless EV technology being developed by Masahiro Hanazawa at Toyota Central R&D Labs and Takashi Ohira at Toyohashi University. Now, there’s a bit more news on this work.

As a refresher, first: a team of Japanese university students have recently displayed a method that could possible say goodbye to the stationary charging station for good, by essentially electrifying the roads on which we drive to perpetually charge your electric vehicle and give it an indefinite range.

The premise is simple: the Electric Vehicle on Electrified Roadway (EVER) system is able to transfer electricity to a vehicle through four inches of concrete and through the cars tires.

Now, on to the recent news…. In their most recent demo — on display at the Wireless Technology Park 2012 — a metal plate was placed along with a four-inch layer of concrete, which represents the road surface. The result? Electricity between 50 and 60 watts was successfully transmitted to standard size automobile tires.

Looks like this technology is moving along nicely. We’ll be keeping an eye on it and let you know of any new developments as they come along.
