Nissan, as well as Mitsubishi and Toyota, are now looking to provide back-up power for households using the electric-powered cars. Nissan has already sold more than 6,000 Leaf EVs and says that electricity converted from the direct current (DC) used in the car battery to alternating current (AC) used in households, can be crucial in the event of an emergency.
Nissan recently said it hopes to have a commercial version of the Leaf-to-Home system ready for sale in Japan next year. Mitsubishi unveiled a similar system earlier this summer, but more recently the two automakers announced a plan to standardize their devices, allowing a Nissan to be able to hook up to a Mitsubishi system and vice versa.
According to Nissan, the Leaf’s 24 kilowatt hour (kwh) battery can store enough juice to power the average Japanese household for two days. Because the average home uses substantially more electricity in the U.S. than in Japan, such a system would not last quite as long here in the U.S.
