ABSTRACT:
An SOC calculating unit calculates a first value based on an open voltage of a battery upon startup of a vehicle (when the operation of the battery starts), and has a calculated second value stored in a storage unit upon stop of the vehicle (when the operation of the battery ends). An initial value selecting unit selects the first value as an initial value when a predetermined condition is satisfied, and selects the second value as the initial value when this condition is not satisfied. In a case where the first value has low reliability, the second value is set as the initial value even if the second value may be deviated from an actual SOC value. This can reduce a difference between the SOC value stored in advance and the actual SOC value as compared with that in a case where the first value is set as the initial value.
