description The present invention achieves a balanced discharging in a power storage system having a plurality of storage batteries connected in parallel. A power storage system comprises a plurality of storage batteries 100a-100f connected in parallel, a storage battery device 120 at least setting an output voltage value at discharge to each of the plurality of storage batteries 100a-100f. The storage battery device 120 includes a discharge control circuit 121 configured to assign at least one storage battery of the plurality of storage batteries for a master based on at least a battery residual capacity or a battery voltage and set the output voltage value so that the output voltage value differs between the master and the storage battery.
