Nissan is working on a system that will let companies regulate their electricity bills using the batteries of Nissan Leaf EVs used by their employees.

The automaker has carried out a successful early field test of the “Vehicle-To-Building” program, which allows up to six Nissan Leafs to be connected to a building's power distribution board.

The idea is to leave charging during the day so at peak hours, when electricity is most expensive, the building can draw power from the cars.

When electricity is cheaper it flows the other way. The cars are fully charged by the end of the working day.

“Vehicle-to-Building” has been in use since July at the Nissan Advanced Technology Center in Atsugi City, Japan. By controlling the charging time of the EVs, the facility benefited from a reduction of 25.6KW during peak summer periods.

Soon, you'll be charging your home with your EV.
