摘要： A controller for managing a battery pack includes: a detection terminal, for transmitting an enable signal when values of battery parameters for the battery pack satisfy a sleep condition, where the enable signal enables the detection circuit to detect whether the battery pack is connected to a load and whether the battery pack is connected to the charger; and a receiving terminal, for receiving a detection result transmitted by the detection circuit. The detection result indicates whether the battery pack is connected to at least one of the load and charger. The controller controls the battery pack to enter a sleep mode of the sleep modes based on the detection result. The controller also includes a control terminal, for transmitting a control signal to control an on/off state of a charging switch and/or a discharging switch. The control signal is generated by the controller based on the detection result.
