ELECTRICAL STORAGE SYSTEM, CONTROL APPARATUS, AND CONTROL METHOD

摘要

In a storage system 1 according to the present invention, a storage battery 10 comprises a plurality of battery modules 14. A battery control unit 30 is connected to the plurality of battery modules 14 included in the storage battery 10 via a communication line 60. A charging/discharging control unit 20 is connected to the storage battery 10 via a power line 50. The battery control unit 30 comprises a characteristic acquisition unit that acquires characteristic information indicating physical characteristics of each battery module 14 from each of the plurality of battery modules 14 and a calculation unit that calculates a setpoint value for controlling the charging and discharging of the storage battery 10 on the basis of the characteristic information of each battery module 14 acquired by the characteristic acquisition unit. The charging/discharging control unit 20 controls the charging and discharging of the storage battery 10 on the basis of the setpoint value calculated by the calculation unit.
