Abstract In the present invention, an acquisition unit of a management unit (30) acquires observation data including the voltages and/or the states of charge (SOC) of a plurality of storage battery packs (20) connected in parallel. A switching control unit is capable of individually controlling a plurality of switches so as to be on or off, on the basis of the difference in voltage between the plurality of storage battery packs (20) or the difference in SOC between the plurality of storage battery packs (20). A capacity calculation unit, when calculating the capacity of all of the plurality of storage battery packs (20), additionally considers the capacity of the storage battery packs (20) connected to switches that are off in cases in which there is a possibility that the switch will be controlled to be on in the near future. Dans la présente invention, une unité d'acquisition d'une unité de gestion (30) acquiert des données d'observation comprenant les tensions et/ou les états de charge (SOC) d'une pluralité de batteries de stockage (20) connectées en parallèle. Une unité de commande de commutation est capable de commander individuellement une pluralité de commutateurs de manière à être allumés ou éteints, sur la base de la différence de tension entre la pluralité de batteries de stockage (20) ou la différence de SOC entre la pluralité de batteries de stockage (20). Une unité de calcul de capacité, lors du calcul de la capacité de toutes les batteries de stockage (20), considère en outre la capacité des batteries de stockage (20) connectées à des commutateurs qui sont éteints dans les cas où il existe une possibilité que le commutateur soit commandé pour être allumé dans un avenir proche. 管理部(30)の取得部は、並列接続された複数の蓄電パック(20)の電圧及びSOC(StateOfCharge)の少なくとも一方を含む監視データを取得する。スイッチ制御部は、複数の蓄電パック(20)間の電圧差または複数の蓄電パック(20)間のSOC差をもとに、複数のスイッチを個別にオン/オフ制御可能である。容量算出部は、複数の蓄電パック(20)全体の容量を算出する際、オフ状態のスイッチに接続された蓄電パック(20)の容量も、当該スイッチが将来においてオン状態に制御されることが可能である場合、加味する。
