JAKARTA - Japanese automaker Nissan Motor Co Ltd and subsidiary Hitachi Ltd announced on Friday January 27 that they plan to launch a system to keep the elevator running during power outages by charging power from electric vehicle batteries (EVs).

Some cars are currently capable of two-way charging, where vehicles can be a source of electricity for the home, or energy returning to the network, even though automakers like Ford Motor Co and Renault SA include jumping on to keep up with the trends that are on the rise.

In what appears to be an early effort in Japan that is prone to earthquakes to use electric vehicle batteries more broadly, Nissan and Hitachi Building Systems Co Ltd focus on keeping elevators operating when power supplies are disrupted.

During the pilot project unveiled last Friday, the company said it had built a nine-person elevator at a slow pace of 10 hours by pulling power from Sakura's battery, a fully electric "kei" microcarf made by Nissan.

"The V2X system uses the CHAdeMO charging standard supported by Nissan," said a Hitachi Building Systems executive.

The system allows it to also attract energy from larger Nissan EVs, such as the Ariya and Leaf models.

Tatsunori Takahashi, director of Hitachi Building Systems' domestic business management division, hopes the company will start providing the system for apartment buildings starting April's financial year.
