SAFT battery cells similar to the ones recently tested to 180,000 miles
One of the key points critics have leveled at the electric car movement is that any money saved by switching gas stations for the power point will be lost when the battery fades and needs replacing. With battery costs currently still high, this is a valid concern - but how long can a battery pack last? Battery provider Southern California Edison have been testing a lithium-ion battery subpack for two and a half hears now and have demonstrated a life of more than 180,000 miles without significant performance deterioration, a figure which makes the cost equation appear more convincing.
