    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.

    Abstract: A battery pack is provided. The battery pack includes: a plurality of battery cells, each of which includes a shell, a battery core, and a plurality of terminal posts. An accommodating space is defined inside the shell. The battery core is disposed in the accommodating space. The shell at least includes a first surface and a second surface. The plurality of terminal posts are disposed on the battery core and extend out of the shell from the first surface. The battery pack further includes an electrical connecting member, which is disposed opposite each of two adjacent first surfaces and is electrically connected to each of two adjacent terminal posts, so as to conduct two adjacent battery cells. The battery pack further includes a heat transfer member, which can transfer heat from the electrical connecting member to the second surface.
