An ECU acquires the SOC, SOH, and degradation time. An anode degradation coefficient is calculated from the SOH and an effective temperature, and a time degradation coefficient is calculated from the degradation time and the effective temperature. The smaller of the anode degradation coefficient and the time degradation coefficient is calculated as an overall degradation coefficient, and an initial input current limit value is calculated from the SOC and the effective temperature. An input current limit value is calculated by multiplying the initial input current limit value by the overall degradation coefficient. The input current of the battery is controlled so as not to exceed the input current limit value. When an anode degradation factor (= SOH × anode resistance increase rate) is greater than 1, the anode degradation coefficient is set to the reciprocal of the anode degradation factor.
