Abstract
A battery pack includes a controller, a battery core, a liquid leakage detector, and a pre-charge switch. The liquid leakage detector is connected with the controller, and the liquid leakage detector is configured to send a liquid leakage signal to the controller when detecting that liquid leakage occurs in the battery core. The controller is configured to prohibit sending a pre-charge on signal to the pre-charge switch upon receiving the liquid leakage signal while receiving a start signal for starting the battery core. The pre-charge switch is configured to prohibit connection of the pre-charge voltage end and the power output end when not receiving the pre-charge on signal, to prohibit the battery core from outputting a pre-charge voltage through the power output end.
