The Electric Vehicle battery is back and this time it faces tough cost and safety challenges. Its mission, however, is less daunting than it was a decade ago. (http://www.designnews.com/article/CA6470737.html?industryid=43655)

The technology that almost buried the electric vehicle (EV) a decade ago is back under the microscope again, as automakers try to develop new batteries for a new breed of EVs.
This time, though, it’s a whole new ballgame.
Instead of having to do the nearly impossible task of lugging around a 2,500-lb electric automobile for 200 to 300 miles between re-charges, the new breed of battery faces a much simpler challenge: Travel 40 miles — or less — on a single charge. Then, if necessary, get a recharge from an on-board internal combustion engine. Makers of the Chevy Volt, a concept vehicle that debuted in January, claim they can get a stunning 640 miles of range using this scheme.
For battery engineers, the resulting technical task has become a less daunting one. With engine-generator backup, the new breed of batteries needn’t be world-beaters. Shorter range means less energy and fewer batteries. Fewer batteries mean less cost. And while there is work to be done, especially with regard to safety, experts say this new electric vehicle mission is a doable one, especially by the targeted 2012 time frame.....http://www.designnews.com/article/CA6470737.html?industryid=43655
Thank you Bruce!
