Abstract: Based on a voltage of a secondary battery detected by a voltage measurement unit, a residual capacity is acquired from a correlation between the voltage and the residual capacity of the secondary battery stored in a memory, and a state of charge (SOC) which is a ratio of the residual capacity to a reference capacity is obtained. The reference capacity is set to a prescribed amount less than a residual capacity at full charge. Further, an information processing unit determines an abnormality of a module based on a comparison between the SOC and an SOC obtained by another method.
