Abstract: A storage battery management device according to one embodiment includes a hardware processor that causes a display device to display first remaining life information and second remaining life information. The first remaining life information indicates current remaining life of a storage battery system. The first remaining life information is calculated on the basis of a state of health (SOH) of each of multiple storage battery modules constituting the storage battery system. The second remaining life information indicates remaining life of the storage battery system and corresponds to a case where one or more of the multiple storage battery modules are replaced with one or more other storage battery modules. The second remaining life information is calculated on the basis of an SOH of each storage battery module not being replaced and an SOH of each of the one or more other storage battery modules.

Abstract: A storage battery management device includes an acquisition unit, a selection unit, an estimation unit, and a display control unit. The acquisition unit acquires a battery characteristic and an operation condition of a storage battery device. The selection unit selects data values from a data value group of a data item in which variation in data value is caused out of data items included in the battery characteristic and the acquired operation condition. The estimation unit estimates, for each of the selected data values, a battery characteristic after operation corresponding to a case where the storage battery device is operated under the operation condition. The battery characteristic is estimated on the basis of the battery characteristic and the operation condition acquired by the acquisition unit. The display control unit displays the battery characteristic estimated by the estimation unit in a comparable state.

Abstract: A storage battery management device according to one embodiment includes a hardware processor functioning as an acquisition unit, a calculation unit, and a display control unit. The acquisition unit acquires, 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. The calculation unit calculates, by using a digital model for simulating operation of the storage battery system, 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 display control unit causes a display unit to display the chargeable/dischargeable capacity, the SOC level change amount, and the SOC maintainable charge/discharge amount.
