It is no longer a
dream to use an electric vehicle battery as a storage battery of a household.
Nissan will put its “LEAF-to-Home” charging equipment on the market in
mid-June. The new product was developed and built by Nichicon. It allows an EV
to be a storage battery of household. It is subject to government subsidy, and
a customer needs to pay 330,000 yen including installation cost.
It supports both AC
and DC. With an output of 6 kW that is two times bigger than the conventional
output, it halved the charging time from eight hours to four hours as an EV
charger. It has the function to monitor power consumption of the household and
charge it at lower than contract current. Because it is possible to set hours for
charging and feeding of the day using a timer, it is rather easy to store cheap
electricity at night and use the stored electricity not only for household but
also for back-up power supply for emergency. A Nissan’s executive said that his
charging equipment could compete successfully with the existing household
storage battery pricewise. Nissan plans to sell 10,000 units in the initial
year. It will start to install the “LEAF-to-Home” in about 2,200 Nissan dealers
across the country.
