    Abstract: In a power storage system, a three-phase AC wire is connected to a three-phase AC power system. Power storage blocks, each of which includes a power storage module and a power conditioner, are connected in parallel to the three-phase AC wire. A system controller individually controls power storage blocks. The power storage modules each includes: a power storage unit; and a management unit that manages the power storage unit. The power conditioner includes a power converter and a controller. The power converter converts DC power discharged into single-phase AC power and outputs the converted AC power to two lines of the three-phase AC wire, or converts single-phase AC power received from the two lines of the three-phase AC wire into DC power and charges the power storage unit. The controller is connected to the system controller via a communication line and the management unit via a communication line.

    Abstract: In each of battery modules, a processing circuit manages a battery unit connected to a power line. A communication circuit communicates data to be transmitted or received by the processing circuit. An isolated circuit insulates in a direct current between a first terminal of the communication circuit and a positive-electrode terminal or a negative-electrode terminal of the battery unit, and between a second terminal of the communication circuit and a conductive body to be a common potential of a plurality of the battery modules except for the power line.
