Title: POWER STORAGE ELEMENT MANAGEMENT APPARATUS AND POWER STORAGE ELEMENT MANAGEMENT METHOD
Abstract:
A remaining capacity is acquired from a correlation between the voltage and the remaining capacity of a secondary battery 30 stored in a memory 63 on the basis of the voltage of the secondary battery 30 detected by a voltage measurement unit 70, and a SOC which is the ratio of the remaining capacity to a reference capacity is calculated. The reference capacity is set to a prescribed amount which is less than a remaining capacity when being fully charged. Further, an information processing unit determines a module abnormality through comparison between the SOC and a SOC calculated by another method.
