Gallery: Wireless Car Charging Could Be Here As Soon as 2013 from Compa...

 

Wireless electric car charging, the technology many said was too inefficient or impractical to be a success, now appears to be a top priority for many automakers and electronics suppliers. We recently told you how Daimler was testing an inductive charging system for the next-generation Mercedes E-Cell vehicle, and we already know Nissan is working on a system for the 2014 LEAF as well as quick-charging systems that can power your house in reverse. Now we’ve discovered that Evatran is making hubcap-sized wireless charging systems for both the LEAF and the Chevy Volt that should be available through Sears next year. And there’s more.

    What is the efficiency of the transfer on devices like this? The wikipedia article on Inductive charging cites 86%. This is not good enough. One of the primary critiques of electric vehicles is that the system losses of bringing the power from the station to the car can cancel out the benefit of burning fossil fuels in the engine. If you add another 14% loss over the last few feet, it becomes untenable.

    The video, though, did inadvertantly bring up a good point. How well weather-proofed are the charging ports on new EV’s? It seemed like leaving that hatch open could cause damage to the interior if there was a storm. perhaps a hatch which could be reclosed and locked, with only enough room at the bottom for the cord to get through would solve this problem and protect your car from roaming pranksters who would pull the plug and leave you stranded.
