STORAGE BATTERY MANAGEMENT DEVICE, STORAGE BATTERY MANAGEMENT METHOD, AND PROGRAM

A storage battery management device according to the present embodiment includes: an acquisition unit to acquire, as current operation state data of a storage battery system including a plurality of storage batteries, charge/discharge power, a cell voltage, a charge/discharge current, and a temperature of a battery board of the storage battery system; a calculation unit to calculate, by using a digital model capable of reproducing operation of the storage battery system in a simulative manner, a chargeable/dischargeable capacity, a State of Charge (SOC) level change amount, and an SOC maintainable charge/discharge amount being a charge/discharge amount maintaining an SOC level within a predetermined range, the calculation unit performing the calculation on the basis of the charge/discharge power, the cell voltage, the charge/discharge current, the temperature of the battery board, scheduled charge/discharge power being a scheduled value of future charge/discharge power, and upper and lower limit values of an SOC of the storage battery system; and a display control unit to cause a display unit to display the chargeable/dischargeable capacity, the SOC level change amount, and the SOC maintainable charge/discharge amount.
