ABSTRACT:
A state of charge calculation device includes an ammeter for detecting charge and discharge currents of a secondary battery, a state detection sensor for detecting a start time of discharge from the secondary battery to an engine, a battery electronic control unit (ECU) for calculating a state of charge of the secondary battery. The battery ECU of this state of charge calculation device calculates the state of charge of the secondary battery, based on the current and voltage detected at the time when discharge starts.
