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.
