Nissan has completed a successful early field test of a system designed to allow companies to use employee EVs to regulate and reduce their electricity bills. Vehicle-To-Building technology allows up to six LEAFs to be connected to a building’s power supply. At peak hours, the building draws power from the cars, then, during off-peak hours when electricity is cheaper, it flows the other way. The system ensures the LEAFs are fully charged by the end of the working day.
The new system has been in use at the Nissan Advanced Technology Center in Atsugi City, Japan, since July. The facility benefited from a reduction of 25.6 kW during peak summer periods, and a 2.5-percent reduction of power use during peak hours.
Nissan’s Vehicle-To-Building system is a further development of its LEAF-to-Home system, which is designed to encourage LEAF owners to charge their cars with electricity generated during the night, when demand is low, or sourced from solar panels. This assists in balancing energy needs and can also be used as a backup power source.
