ABSTRACT:
A battery pack having a plurality of electrically connected unit cells and configured so that the cells degrade at similar rates is provided. The battery pack may comprise a first unit cell and a second unit cell, wherein a temperature of the second unit cell is lower than the first unit cell. A condition of the first cell, such as states of charge or an open circuit voltage is set so that the condition of the first unit cell is less than a corresponding condition of the second unit cell. The unit cells may be thin battery cells stacked in a thickness direction of the thin battery cells, and the first unit cell may be located on an inner side of the second unit cell as viewed in a stacked direction. A temperature detecting unit may detect a temperature of each of the first and second unit cells and a charge control unit may be configured to control charging of the plurality of unit cells according to the temperatures of the first and second unit cells. With this configuration, even when the temperatures of the unit cells are not uniform, the rates of deterioration of the unit cells are equalized as much as possible.
