Japan, a country which frequently suffers natural calamities such as tsunamis, typhoons, and earthquakes—which can often paralyze energy supplies—is looking to further harness the power of batteries used in electric vehicles (EVs) during such disasters, local media reported (paywall) yesterday (Feb.20)Nissan, which produces the Leaf, the world’s best-selling EV model, plans to hold an event in March to let people stay overnight in their cars and try using the electricity stored in their car batteries to simulate the experience of being in an emergency, according to Japanese newswire Jiji (link in Japanese). A fully charged electric vehicle can supply power to a standard home for up to four days, a Nissan official told the news outlet.The company last year came to an agreement with Tokyo’s Nerima Ward and the city of Yokosuka to provide EVs for free in emergency situations. Nerima also last year (link in Japanese) implemented a system whereby owners of EVs would be able to loan their vehicles out for free to those in need during a disaster, and also started using EVs for its fleet of police patrol cars.Nissan explained the concept of using EVs as a power source in case of a disaster in a video it made in 2017. When a disaster hits, it can take more than a day to restore electricity, and during that period, EVs can be used as an emergency backup to supply energy for heating, cooking, and telephones
