The Nissan Leaf can run 70-plus miles on a single charge. Now, it can also power a family home for two days if it needs to. The “Leaf to Home” project Nissan is rolling out in Japan allows the electricity stored in the Leaf’s lithium-ion battery to be fed back into a home, running major appliances for up to two days.

The “Leaf to Home” system simply allows for a quick charging port to be mounted on the home’s electricity distribution panel to receive energy from the car. Those 24 kilowatt hours stored in a fully energized Leaf can run the average Japanese household for two days, even when the refrigerator, climate control, and other large appliances are running at the same time.
