Nissan has unveiled a new power supply system that enables electricity to be supplied to homes from the lithium-ion batteries installed in its LEAF electric vehicle. The new system was unveiled at Kan-kan-kyo, a house built by Japanese firm Sekisui House and located in front of the Nissan Global Headquarters in Yokohama.

The Power Control System, as it’s called, is a sinusoidal PWM system with a 6kW rating, and runs on a 200 volt single-phase. three-wire configuration. Through it, electricity stored in the 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, which are adopted globally.

As such, the 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 24 kWh of electricity, sufficient to power an average Japanese household for about two days.

The system, the company says, will allow households to be supplied with a stable amount of electricity throughout the day, and charge and store electricity back in the car with electricity generated at night or through methods such as solar power. The PCS allows both electricity supply to be drawn from the vehicle as well as for the charging of the vehicle.

Current LEAF owners will also be able to use the system, though there is a need for some adaptation to be carried out. The company aims to commercialise the system somtime later this year.
