Original Abstract Submitted
The control unit includes: when an absolute value of a difference between a full charge capacity of a 1 cell and a full charge capacity of a 2 cell is equal to or larger than a 1 threshold value, equalization is performed so that an absolute value of a difference between a charge rate of a 1 cell and a charge rate of a 2 cell at the time of full charge is less than a 2 threshold value, and when an absolute value of a difference between a voltage of a 1 cell and a voltage of a 2 cell is equal to or larger than a 3 threshold value, equalization is performed so that an absolute value of a difference between a voltage of a 1 cell and a voltage of a 2 cell becomes less than a 3 threshold value.
