ELECTRICITY STORAGE SYSTEM

摘要

An electricity storage system includes an electricity storage device, a positive electrode line, a negative electrode line, a capacitor, at least two diodes, and a first intermediate line. The electricity storage device is able to supply power to a load. The electricity storage device includes at least two electricity storage groups connected in series. The electricity storage group includes at least two electricity storage elements connected in series. Each electricity storage element includes a current breaker. The capacitor is connected to the positive electrode line and the negative electrode line. At least two diodes are connected in series between the positive electrode line and the negative electrode line and are respectively connected in parallel to the electricity storage groups. The first intermediate line is connected between a first connection point and a second connection point. At the first connection point, the electricity storage groups are connected together. At the second connection point, the diodes are connected together.
