Abstract:
1. A battery pack capacity adjustment apparatus for a battery pack constituted by connecting in series a plurality of cells, comprising: capacity adjustment circuits each provided in correspondence to one of the plurality of cells to execute a capacity adjustment by discharging the corresponding cell if a voltage at the corresponding cell exceeds a predetermined bypass engaging voltage; a power generation device that generates power used to charge the battery pack; a capacity adjustment decision-making device that makes a decision as to whether or not capacity adjustment needs to be executed for the battery pack; a target power generation calculation device that calculates target power to be generated based upon the bypass engaging voltage; and a power generation control device that issues a power generation command for the power generation device so as to generate the target power calculated by the target power generation calculation device if the capacity adjustment decision-making device determines that the capacity adjustment is necessary.
