Ever since the power went out in large parts of Japan after a massive Tsunami slammed into the country on March 11, the big question no longer is “will I be able to charge my EV at home.” It is: “Will I be able to power my house with my car?” This may seem alien to you, but a Tsunami has certain effects, and this is one of them. At a press conference in Yokohama, reporters asked Nissan’s CEO Carlos Ghosn: “When will it discharge?” Meaning the Leaf into the house. A few days later, Toyota showed a house that can be powered by a plug-in Prius should the lights go out. Now Nissan finally shows its great chargeback solution.
In front of Nissan’s global headquarters in Yokohama, on one of the world’s priciest waterfront properties, Sekisui House Ltd. erected a model home that can draw electricity from the lithium-ion batteries in a Nissan LEAF.
With this system, Nissan LEAF can be used as a backup battery in case of a power outage. The batteries in a LEAF store up to 24kWh of electricity, enough to power an average Japanese household for about two days, says Nissan.
The electronic gadgetry appears to be farther ahead that Toyota’s where the reverse charge still needed a bit of work when we inspected the home. If needed, 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.
Current Nissan LEAF owners can use the system as long as they make the needed adjustments to the home wiring. More information (in Japanese) here.
