I was talking to a family member, who has a Renault garage nearby. He was talking to the proprieter, an acquaintance, who says that the 2011 electric cars will have a leased battery, which may be exchanged at a garage (for a charged one), or charged at home. I wonder whether a standard for these batteries will be forthcoming, so that ones from different manufacturers will be interchangeable. I mentioned this in another place, & I'm glad that the idea seems to've been at least partly thought of by a car maker!
