Electric vehicles to back up the power grid

Power 1

holy_calamity (872269) writes "Researchers in Delaware are working with electricity grid giant PJM on a scheme to use the batteries of electric vehicles to backup the grid while parked. Cars typically spend 23 hours a day off the road. During that time electric or plug-in hybrid vehicles can soak up excess generated power or trickle juice into the grid to smooth out mis-matches between supply and demand. Just 100 electric vehicles running the vehicle-to-grid software like their current prototype can provide 1MW of storage. City officials in Austin, Texas are keen to try the idea."

that the increased rate and number of charge cycles will kill more quickly. (And, please don't tell me about memory-free battery technology, because as much as it has been promised again and again it still has yet to prove to be true.)
