Nissan Creates Kit for Leaf to Power Homes for 2 Days

By Jacob Brown | November 29, 2011
The Tokyo Motor Show isn’t just about new cars. It’s also about new ideas. Showcased at this year’s event, Nissan is introducing a kit called the Home Smart Charging for the Leaf electric car. With it, the automaker hopes to channel the electricity stored in the Leaf’s 24-kilowatt battery pack to balance the electric grid, reduce electricity bills, and run a home for up to two days in the event of a power outage. The Nissan Leaf uses a home charging station called a Power Control System. Using it in conjunction with the smart charger, Nissan will be able to run a Japanese home, which uses about 12 kilowatts of electricity per day on average, for two days.
Nissan says that the modulator won’t hurt the life of the battery in the Leaf, as it puts a lot less strain the battery than normal stop and go driving. The automaker is planning on launching the Home Smart Charging system in Japan at an expected cost of around 500,000 yen, or a little less than $6500 at current exchange rates. Company officials say that more widespread purchasing of the system will drive down costs. Because Japan’s alternating current runs differently than our electricity grid, the technology involved in the smart charger may take a while to get to the U.S., if at all. However, Japanese buyers should be able to get their hands on the Home Smart Charging unit as early as summer 2012. Source: Autocar
