蓄電池管理装置、方法及びプログラム
Document Type and Number:
Japanese Patent JP6301935
Kind Code:
B2
Abstract:
A storage battery management device according to an embodiment includes a chargeable/dischargeable capacity table that 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; a controller that 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; and a communication controller that informs a host device about the calculated chargeable/dischargeable capacity of the secondary battery. Even in a storage battery system that repeats charging/discharging constantly, this configuration can correctly estimate the actual chargeable/dischargeable capacity and stably operate the storage battery system.
