Abstract: The present invention relates to a battery pack and a vehicle. The battery pack includes a liquid cooling plate (1), and a battery stack (3) including at least one battery module (31). The liquid cooling plate (1) includes a liquid cooling plate body (11), a liquid inlet (12) and a liquid outlet (13). The liquid cooling plate body (11) is internally provided with a liquid cooling circuit, which includes a peripheral liquid inflow channel (111), an effluent liquid collecting channel (112), and an intermediate channel (113) communicating between the peripheral liquid inflow channel (111) and the effluent liquid collecting channel (112). The liquid inlet (12) is connected onto the liquid cooling plate body (11) and communicates with the peripheral liquid inflow channel (111). The liquid outlet (13) is connected onto the liquid cooling plate body (11) and communicates with the effluent liquid collecting channel (112). At a low temperature, the battery pack of the present invention matches the heating requirements of different areas, and gives more heat to the peripheral area of the battery pack, to control the temperature difference in the battery pack.
