摘要： A battery pack includes at least a lithium ion secondary battery, a voltage sensor, and a control unit. The control unit controls discharge of the battery by a relatively high end-of-discharge voltage when the use frequency of the battery is relatively low during discharge of the battery. On the other hand, the control unit controls discharge of the battery by a relatively low end-of-discharge voltage when the use frequency of the battery is relatively high. Consequently, it is possible to prevent the utilizable capacity from decreasing more than a practical decrease in the capacity due to increase in the use frequency.
