As part of its Nissan Ambition 2030 vision, Nissan will support the policy of Namie, Fukushima Prefecture, to produce energy for local use and achieve carbon neutrality. The OEM will soon begin verification tests of the energy management system it has established in the town. This system utilizes an autonomous control system that generates 100% renewable energy for charging EVs by sending electricity to and from them.

Two problems faced by renewable energy are fluctuations in power generation caused by weather conditions, and an imbalance in the supply and demand of electricity. Combining large-capacity EV batteries with a system that charges and discharges them independently allows renewable energy to be used more effectively and can stabilize the power grid.

Nissan’s decentralized autonomous control system will enable Namie’s five EVs to be charged or discharged based on the amount of electricity generated by solar, wind, and hydrogen fuel cells. The electricity demand of the town’s commercial facility will also be accounted for in this process.

To determine the optimal timing for recharging and discharging the EVs, the system considers their battery status and usage patterns. Nissan expects the system to lower the peak power consumption of Namie’s commercial facility and reduce electricity costs.
