Abstract
An acquisition unit of management unit acquires monitoring data including at least one of voltage and state of charge of a plurality of power storage packs connected in parallel. A switch controller can individually control on/off of a plurality of switches based on a voltage difference between the plurality of power storage packs or an SOC difference between the plurality of power storage packs. When calculating the entire capacity of the plurality of power storage packs, a capacity calculator also adds the capacity of power storage pack connected to a switch in an off state in a case where the switch can be controlled to an on state in future.
