Abstract
A battery pack includes one or more battery cells, a control circuit, a communication circuit, and a switching control circuit. The switching control circuit is configured to switch the control circuit from a controlled-operation state to a low-power operation state in response to a communication-stop time exceeding a state-switching threshold, the communication-stop time being a duration of a state in which the control circuit or the communication circuit detects no communication with the charger, and the state-switching threshold being determined in advance, so that power consumption of the control circuit can be reduced upon completion of a charging operation.
