POWER STORAGE SYSTEM

Abstract:

A power storage system capable of appropriately increasing a temperature of a power storage device is provided. A power storage system (10) includes a battery (31) and a plurality of AC application units (33). The battery (31) includes a string (31b) which is formed by a plurality of cells (31a) connected in series to each other. The battery (31) includes a plurality of modules (35) which are formed by dividing the string (31b) into a plurality of substrings in series. The plurality of AC application units (33) respectively apply alternating currents I having phases set to attenuate a voltage fluctuation at both ends (the positive electrode terminal (BP) and the negative electrode terminal (BN)) of the battery (31) to each of the plurality of modules (35).
