Nissan Unveils New Power Supply System Through Nissan LEAF

New Power Supply System Through Nissan LEAF

YOKOHAMA – 08/02/2011 – Nissan Motor Co., Ltd. today unveiled a system which enables electricity to be supplied from the lithium-ion batteries installed in Nissan LEAF to ordinary households, as part of its comprehensive efforts toward the realization of a zero-emission society.  The new system was unveiled at ‘Kan-kan-kyo’1, a house built in front of the Nissan Global Headquarters by Sekisui House Ltd.  Nissan will continue development and study how it can be fully aligned and connected with current power systems.  Working with a wide range of partners interested in both its development and sales, Nissan aims to commercialize the system during this fiscal year.

Through this system, electricity stored in Nissan LEAF can be supplied to a house by connecting the car to the house’s electricity distribution panel using a connector linked to the LEAF’s quick charging port.  The connector complies with the CHAdeMO Association’s protocol for quick chargers, adopted globally for its great versatility, safety and reliability.

With this system, Nissan LEAF can be used as an electricity storage device for houses in preparation for power outages and/or shortages.  The lithium-ion batteries can store up to 24kWh of electricity, sufficient to power an average Japanese household for about two days2.

Nissan believes this system will allow households to be supplied with a stable amount of electricity throughout the day and reduce the burden on the current power supply by charging and storing electricity in Nissan LEAF with electricity generated at night or through sustainable methods such as solar power, and using it during high demand periods.

This system can not only supply electricity from the vehicle but also charge it to the vehicle.  Current Nissan LEAF owners will also be able to use this system3.
