Can Your Car Charge Your House? The Leaf Can

Nissan recently introduced a system that allows the electricity produced by the lithium-ion batteries in the Nissan Leaf to be transferred to households.  The system was unveiled at the Kan-kan-kyo house, which was built in front of the Nissan Global Headquarters in Yokohama, Japan, by Sekisui House, as a way of demonstrating new technology.

Using a connector linked to the Leaf’s charging port, electricity can be transferred to a house to power appliances and lighting, and the Leaf can do double duty as an energy storage unit when it’s not being used for transportation. The batteries can store up to 24 kilowatt hours (kWh) of electricity, which is said to be enough to power the average Japanese household for about two days.

The system is still in its developmental stages, but Nissan plans to make it available to the public during this fiscal year with the help of partners worldwide in both the development and marketing areas. Currently, Nissan is studying the best ways to integrate the new system with existing power systems.

The goal of the system is to provide households with stable power while reducing the strain on the current power supply from the grid by storing electricity generated at night, when electricity demands are lower, or through sustainable methods like solar or wind power. This will, they hope, lead to fewer emissions and more efficient energy use.
