Nissan LEAF Household Power Supply System


We’re not sure we’re getting this right, but Nissan has just announced a new system that can use the electricity stored in the Nissan LEAF’s batteries to power households!

Now, last time we checked Nissan LEAF, and indeed all electric cars, were having difficulty to hold on its charge to provide sufficient range for the car to go anywhere. They are in desperate need of a household socket to top up the batteries. So who expects them to use the electricity to power a house, which in the first place is supposed to power the LEAF?!

The new system was unveiled at ‘Kan-kan-kyo, 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.

Maybe there’s a bigger logic behind this that we don’t understand! For example they say this system can be used to power the house in case of a power outage. But given the costs of buying a Leaf and the supply system, it doesn’t really make sense!

Here’s Nissan’s official details on the system, see if you can work it out:

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.

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 days*2.
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 system*3.
