As I wrote in a recent Times article on electric car batteries, scientists expect big breakthroughs in battery technology over the next five years that the range of electric cars will increase while reducing their costs. But even with this progress, researchers acknowledge that no rechargeable battery gradually his ability to save energy will lose after repeated cycles of charging and discharging.
Once storage capacity falls below a certain level, the battery can no longer the range that offer electric car owners, according to Micky Bly, the Executive Director of global battery, hybrid and electric vehicle engineering at General Motors will expect. For her new Chevrolet Volt expects G.M. that level at about 60 to 65 percent of its original capacity of the battery, he said in a telephone interview.
At the same time, with most of the useful life of a battery still intact, automakers anticipate that other, less demanding purposes than feeding a few thousand pounds of car could serve.
