ABSTRACT:
The state-of-charge adjusting apparatus which enables to shorten a time to reach a capacity equalization is provided. A CPU extracts a block consisting of a plurality of unit cells connected continuously to each other, the plurality of the unit cells each having a voltage higher than a target voltage, and connects both ends of each block to a discharge resistance to make each block discharge. Thereafter, the CPU extracts a unit cell having a voltage higher than the target voltage and connects both ends of the extracted unit cell to the discharge resistance to make the extracted unit cell discharge until the voltage of the extracted unit cell reaches the target voltage.
