How the World's Fastest Electric Car Is Pushing Wireless Charging Tech

Posted by timothy on from the amping-up dept.

An anonymous reader writes With the first ever season of Formula E revving up in China next month, it's clear there's more to electric cars than Tesla. But the race cars hitting the track in Beijing don't have anything on the speed of Drayson Racing Technology's Lola B12 69/EV, which holds the record for the world's fastest lightweight electric car, and which uses the kind of power technologies that could one day have applications off the track too—like charging your phone wirelessly.

    Let's do the numbers: if you want this 30 kWh battery charged in one hour (you're in a race, remember?) you'll have to supply 30 kW. At an efficiency of 80% (TFA -- I know, I know) you're looking at losses of 30 * (1/.8 -1) kW = 30 * .25 kW = 7.5 kW. That's a friggin' garage heater!

    I'd still go with a thick copper plug, really.
