Hillside, New Jersey – Nissan is working on a version of its all-electric Leaf that could provide electricity for a household in a power outage, the company said.

Hideaki Watanabe, head of Nissan’s global zero emissions business unit, said the automaker is currently working on a car that could work as a generator capable of powering an entire house for about a day. The Leaf’s battery can currently store 24 kilowatt hours of electricity, which is about 24 hours’ worth of energy used by the average U.S. household.

“In Japan, some people say instead of installing a generator, they’ll just buy a Leaf,” Watanabe said.

The current Leaf, which will go on sale in Canada this fall, doesn’t come with a function to discharge power. Watanabe has asked his engineers to come up with a concrete proposal and a prototype capable of reversing the energy flow, which he expects by the end of this year.
