Abstract: Until an elapse of a predetermined time changed in accordance with a temperature of the secondary battery from the time of IG-off, the battery voltage is detected cyclically, and an open circuit voltage in a state where the polarization is cancelled is sequentially estimated based on a shift of the battery voltage. In a case where the IG switch is turned on after the elapse of the predetermined time, the battery voltage detected at the time of IG-on is assumed to be the open circuit voltage, and then an initial SOC at the time of starting use of the secondary battery is estimated. In a case where the IG switch is turned on before the elapse of the predetermined time, the estimated opening circuit voltage at that time point is regarded as the open circuit voltage, and the initial SOC of the secondary battery is estimated.
