Nissan LEAF and the EV Power Station

Nissan has decided to provide 47 LEAFs and 47 LEAF-to-Home power supply system to roadside rest areas in all 47 prefectures of Japan.

These donated unit will promote Nissan EVs and, more importantly, provide power in the case of natural disasters and enhance the daily lives of local residents.

The Japanese manufacturer plans to start deliveries this month. The donated LEAFs will come from dealers, as used demo cars.

"Electric vehicles can serve as portable sources of electrical power both in day-to-day living and during emergencies such as power blackouts following earthquakes or hurricanes. The Nissan LEAF, paired with the LEAF to Home power supply system, can be used as back-up power source in emergency situations if there are power outages and/or shortages by providing the stored electricity held in the Nissan LEAF’s onboard batteries. In normal situations, the LEAF to Home power supply system helps stabilize the electrical grid and balance energy needs by charging an EV with electricity generated during the night, when demand is low, or sourced from solar panels and supplying it to homes during daytime when demand is high."

The EV Power Station device that implements LEAF-to-Home and utilizes CHAdeMO standard has charging and discharging power of 6 kW, which mean that a 24 kWh battery pack can be charged or discharged in a few hours.
