  • Publication number: 20220209319
    Abstract: There is provided a power storage system including a plurality of storage battery modules connected in parallel with a load. The power storage system includes: a resistance value calculating unit that calculates a resistance value of each storage battery module of the plurality of storage battery modules; a current value calculating unit that calculates a permissible current value of each storage battery module of the plurality of storage battery modules; and a determining unit that determines a maximum value of a current. The determining unit determines the maximum value such that a value of a current divided into each storage battery module of the plurality of storage battery modules does not exceed the permissible current value of each storage battery module of the plurality of storage battery modules based on a ratio of the resistance value of each storage battery module of the plurality of storage battery modules.
