Abstract

To increase input / output for charging and discharging in a power storage system in which a plurality of storage batteries are connected in parallel.SOLUTION: A storage battery control device 100 controls a power storage system 1 that comprises a plurality of storage battery cells C1 to Cn connected in parallel and a plurality of switches S1 to Sn. The storage battery control device 100 controls disconnection and connection of the storage battery cells C1 to Cn by the switches S1 to Sn so that the storage battery cells C1 to Cn that increase an input or output current of the power storage system 1 are preferentially connected with a charging line CL or a discharge line DL by the switches S1 to Sn.SELECTED DRAWING: Figure 1
