EV goes 375 miles @ 55MPG -- and charges in 6 minutes!

Electric Car Drives 375 Miles at 55 mph, Recharges In 6 Minutes - All Cars Electric

Converted Audi A2 claims new electric vehicle distance record: 372 miles — Autoblog Green



The battery pack is 115kWh and there are still 4 seats in the car -- wow. This could be it?

The Audi A2 is probably the best car America never got. I would love to have an A2 in my garage, parked next to the Insight, with one of them converted to EV.

Obviously, the defining feature of this EV is its battery. 115KWh is enormous. It's also probably over 2000lbs of battery, which would be more than the weight of the rest of the car. Hence the rather poor showing of 253Wh/mi at the battery at 55mph. If they had used cheap LiFePO4 cells, it would still cost over $50k for the batteries alone. Such a car can never be a daily driver.

That claim of charging a 115KWh battery in six minutes should raise more than one red flag. That would require an average charge rate of 1.15 Megawatts! The article also didn't mention how long the batteries would last if you applied such enormous current to them every day.

It's a nifty record car, but they should have added a boat tail and shot for 500mi.

At some point, adding more battery reduces your range by increasing rolling resistance. I wonder how close this car was to that point.

...where do they "plug" it into for that kind of "recharge," (a) into an ELECTRIC chair or (b) directly into Boulder DAM (wink,wink)???

That whole 6 minutes to charge time worries me....does it require a bolt of lightning to obtain that?

If you wanted to recharge it in 6 minutes, you'd need more than the local grid could supply. You'd need an even bigger battery of your own.

115kwh battery recharged in 6min...if you had access to a 480V industrial connection it would still be >2000A.

You really only need a battery a third that size anyway.

It'd be cool to be able to leave 1/2-2/3 of the batt pack at home when you know you won't need it to save the weight and gain the space!
