Abstract: A battery pack, a method for controlling a battery pack, and a vehicle. The battery pack includes a control module (101), a battery core (102), a liquid leakage detection module (103), and a pre-charge switch module (104). The liquid leakage detection module (103) is connected with the control module (101), and the liquid leakage detection module (103) is configured to send a liquid leakage signal to the control module (101) when detecting that liquid leakage occurs in the battery core (102). The control module (101) is configured to prohibit sending a pre-charge on signal to the pre-charge switch module (104) upon receiving the liquid leakage signal while receiving a start signal for starting the battery core (102). The pre-charge switch module (104) 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 (102) from outputting a pre-charge voltage through the power output end.
