Title:
二次電池の管理装置および二次電池の管理方法
Document Type and Number:
Japanese Patent JP6610558
Kind Code:
B2
Abstract:
A management device manages a secondary battery which includes a positive electrode having an active material with a characteristic where a potential flat portion exists in a relationship between a capacity and a potential. The management device includes a management unit which detects an occurrence of temporary degradation of the secondary battery when an SOC correlation associated value which is associated with an SOC of the secondary battery is acquired and the SOC which corresponds to the acquired SOC correlation associated value is equal to or less than a preset prescribed SOC or when a state value relating to a voltage of the secondary battery is acquired and a magnitude relationship between the acquired state value relating to the voltage of the secondary battery and a preset threshold value satisfies a predetermined condition.
