APPARATUS FOR CONTROLLING ELECTRICITY ACCUMULATION APPARATUS, ELECTRICITY ACCUMULATION APPARATUS AND METHOD OF CHARGING AND DISCHARGING ELECTRICITY ACCUMULATION APPARATUS

摘要

An electricity accumulation device has a dedicated charge terminal that connects to a distributed power generation system such as a solar power generation system and a grid-dedicated discharge terminal that connects to the power grid, a grid-dedicated charge terminal that connects to the power grid and a discharge terminal for discharging to an electric load such as an electric apparatus. The electric power charged to the electricity accumulation device can be made between an electric power generated by the distributed generation and an electric power generated by the power grid, by providing an electric power measurement device for each charge terminal and each discharge terminal that connects to the distributed generation, and thus charge and discharge control can be performed.
