<p>A total SOC of a battery pack including a collection of a plurality of battery blocks is calculated based on a plurality of block SOCs representing respective stored charge amounts in the plurality of battery blocks. In the case (401) where a block SOC maximum value (BSmax) is higher than a control upper limit value (SOCu), the total SOC is calculated to be higher than the control upper limit value. On the other hand, in the case (402) where a block SOC minimum value (BSmin) is lower than a control lower limit value (SOCl), the total SOC is calculated to be lower than the control upper limit value. Further, in the case (403) where each of the block SOCs is in a range of not less than the control lower limit value and not more than the control upper limit value, the total SOC is determined to fall within the range of not less than the control lower limit value and not more than the control upper limit value.</p> |
