The Nissan LEAF to HOME charger, which looks to be, in part, a response to the emergency situation after the 2011 earthquakes in Japan, can provide electricity for your home from your car battery. For the over 10,000 current EV owners in earthquake prone California, its another reason to encourage your friends and neighbors to consider the vehicle-to-grid (V2G) technology. Another idea is the regular use of a EV battery to store cheap off-peak electricity to be used during peak hours. This could make an interesting variable in the PEV calculator. While V2G looks like something further down the road, this could present some considerable cost savings in the short term. EV owners that mostly work from home, what do you think?
