Home Power Supply

June 19, 2012

Owners of the electric Nissan Leaf in Japan can now use their cars as backup power supplies for their homes. Nissan’s Leaf to Home system converts DC power from the car’s battery to AC power compatible with home appliances. Once connected to a household electrical panel, it delivers power through existing wiring to plugs throughout the house. The Leaf stores enough electricity to supply an average Japanese home for about two days.
