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."

Solar photovoltaic and fuel cells generate direct current. Usually they go through an inverter, that loses 10-25% of the energy (as heat, and burns out the part for replacement about every 5 years). A battery like this would mean keeping that energy without losing it. Leaving a battery charging at home while driving the car around, then swapping it into the car when the car returns home - or reverse the positions for batteries charging at work or at whatever daytime destination. That battery can also power household devices, like the many devices that really consume DC, which waste power running from wall current into rectifiers.

This kind of device could improve not only transit energy, but also residential (and commercial sites that reverse the locations).
