Abstract
According to one embodiment, a storage battery management device includes a chargeable/dischargeable capacity table, a controller, and a communication controller. The chargeable/dischargeable capacity table stores therein in advance a chargeable/dischargeable capacity corresponding to a temperature, a state of charge (SOC), a required charge rate or discharge rate, and a battery degradation rate of a secondary battery. The controller calculates an actual chargeable/dischargeable capacity by referring to the chargeable/dischargeable capacity table based on the temperature, the SOC, the required charge rate or discharge rate, and the battery degradation rate of the secondary battery. The communication controller informs a host device about the chargeable/dischargeable capacity of the secondary battery.
