    Abstract: The present disclosure provides a battery pack and an electric vehicle. The battery pack includes a casing wherein the battery is placed, a cooling plate located below the casing in a height direction, and a bracket assembly located below the cooling plate in a height direction and fixedly connected to the casing, the bracket assembly is used for direct contact with a mounting plate of the electric vehicle. When the battery pack of the present disclosure is used in an electric vehicle, since the bracket assembly separates the cooling plate from the mounting plate of the electric vehicle, the cooling plate does not need to directly exchange heat with the mounting plate, thereby reducing the influence of the temperature of the mounting plate on the cooling plate, and increasing the cooling or heating efficiency of the cooling plate to the battery inside the casing.

    Abstract: The present disclosure relates to a casing for a battery pack and a battery pack. The casing has a receiving space and an opening in communication with the receiving space, the receiving space is formed by a wall portion of the casing, and the wall portion is formed from two or more stacked base plates, between which a plurality of cavities are formed, wherein an island is disposed within the cavity. By disposing islands in the plurality of cavities, the casing provided by the present disclosure not only can improve the structural strength of the casing and of the cavities, but also can change the flow capacity and flow rate of the fluid in the cavities, which can make the temperature distribution of the casing more uniform, increase the heat exchange efficiency of the battery assembly, and further improve the thermal management of the battery pack.
