1. A power storage system comprising:
a power storage device which is formed by connecting a plurality of power storage elements;
a plurality of modules which are formed by dividing the power storage device into a plurality of parts, wherein the plurality of modules are (m×k) modules by any natural number m of 2 or more and any natural number k and k module sets are formed by m modules sequentially adjacent to each other; and
a plurality of AC application units connected in parallel to different modules of the plurality of modules and configured to apply alternating currents to the respective modules, wherein
each of the plurality of AC application units comprises an AC power supply configured to generate the alternating current and a transformer connected in parallel between the respective module and the respective AC power supply and configured to transform an AC power of the respective AC power supply, and wherein
a plurality of phases of the alternating currents generated by the AC power supplies of the plurality of AC application units are sequentially offset from each other by (360°/m).
