Nissan Claims Its New Charging System Can Fill Up Electric Cars in Ten Minutes

The Leaf's "Engine" Seth Fletcher

We all know that one of the biggest obstacles to electric car adoption is the long, often overnight recharge time. But Nissan claims that they've created a new charging system that'll fill up your car (Nissan would undoubtedly prefer to say "your Leaf") in only ten minutes--not much different than a regular trip to the Earth-killing pump.

AFP reports that Nissan, working with Japan's Kansai University, has come up with a breakthrough in electric charging tech. Details are scarce at best--Nissan isn't clarifying anything to reporters--but here's what's been reported: "The breakthrough reportedly came by changing the electrode inside a capacitor from carbon to tungsten oxide and vanadium oxide to improve power."

There's a lot missing from that, obviously. Something may have gotten fouled up in translation--we suspect they meant "battery" rather than "capacitor"--but what it sounds like is that Nissan has come up with a new battery tech that uses tungsten oxide and vanadium oxide rather than carbon. The general bottleneck in reducing charging time isn't in the charger or the amount of power that can be pumped into batteries, but rather in the frailty of the batteries themselves--the cells can't handle too much current at once. So a new battery technology that can cope with a very high amount of energy without degradation could conceivable allow that kind of super-fast charging. [via NY Daily News]  Via popsci.com
