STORAGE BATTERY CONTROL APPARATUS AND STORAGE BATTERY CONTROL METHOD

A storage battery control device in embodiments includes a first reception unit, a second reception unit, a calculation unit, a generation unit, and a transmission unit. The first reception unit receives a charge and discharge command from a power management device. The second reception unit receives a current electricity storage state from each of a plurality of storage batteries. The calculation unit calculates a control amount, which indicates a ratio of the current electricity storage state in an operation range, with respect to each of the plurality of storage batteries on the basis of the current electricity storage state and the operation range of the electricity storage state. The generation unit generates a charge and discharge output value, which is an output value of charge and discharge for the each of the plurality of storage batteries, on the basis of the control amount that is calculated for each of the plurality of storage batteries, and the charge and discharge command that is received. The transmission unit transmits the charge and discharge output value, which is generated, to each of the plurality of storage batteries.
