Standardizing Power Supply from EVs to Homes


Nissan Motor Co. and Mitsubishi Motors Corp. are moving to standardize the specifications for supplying electricity from electric vehicles (EVs) to homes and other facilities, the Yomiuri Shimbun reported on August 13. If the differences in specifications among manufacturers, which have been a challenge for smart power management, are resolved, this market is likely to grow further in the future.

A De Facto Domestic Standard?



Electric vehicles have garnered increasing attention as "driving batteries" since the Great East Japan Earthquake. Nissan and Mitsubishi are each planning to release devices this fiscal year that connect EVs to homes. However, due to the current lack of compatibility between their systems, users who install, for example, a Nissan device in their homes are inconvenienced by being limited to Nissan vehicles.

The batteries in electric vehicles can store enough power to supply a typical household for one to two days. Since the current is direct current (DC), a device is needed to convert it to alternating current (AC) for supply to homes. If both Nissan and Mitsubishi, leaders in the domestic EV market, unify their specifications, it could effectively become the domestic standard.

In the near future, EVs are expected to play a role as batteries within society's energy infrastructure. With this in mind, OPENERS is now advocating for EVs asSNV (Social Network Vehicle)This move towards standardizing specifications will likely be a significant step forward in promoting such SNVs.
