Electric Car Goes 375 Miles On One 6-Minute Charge
thecarchik writes with this quote from AllCarsElectric:
"We all know that battery packs are the weakest link in electric vehicles. Not only are they heavy and expensive, but they take a long time to recharge and on average can only provide around 100 miles per charge. A German-based company has changed all that with a new vehicle capable of driving up to 375 miles at moderate highway speeds. ... It doesn't end there. The company responsible for the battery pack, DBM Energy, claims a battery pack efficiency of 97 percent and a recharge time of around 6 minutes when charged from a direct current source. Unlike the small Daihatsu which was heavily modified by a team in Japan earlier this year that achieved a massive 623 miles on a charge at around 27 mph, the Audi A2 modified by DBM Energy was able to achieve its 375 miles range at an average speed of 55 mph."
I wonder if there is a device that would only allow electricity to pass in one direction. If there was, I could envision a small array of these devices set up in a kind of diamond pattern, such that AC going in could end up as DC coming out. Granted, the DC would still have the peaks and troughs of the AC, but maybe that could be 'smoothed' out with some kind of intermediate electricity 'buffer' if there is such a thing.
Interesting.
