The battery box body is provided with a cooling chamber, the cooling chamber is provided with a cooling liquid inlet, a plurality of accommodating cavities and a cooling liquid outlet which are communicated in sequence, the accommodating cavities are used for placing battery cells, and the cooling liquid inlet and the cooling liquid outlet are both used for being connected with an external cooling liquid circulating system. Cooling liquid sequentially flows through the cooling liquid inlet, the containing cavities and the cooling liquid outlet, wherein the containing cavities and the cooling liquid outlet are communicated in sequence. In the battery box body, the cooling liquid is directly contacted with the battery cells to take away the heat of the battery cells, and the cooling liquid sequentially flows through each accommodating cavity, so that all the battery cells in the battery pack can be uniformly cooled, the heat dissipation uniformity of the battery pack is considered, and the heat dissipation effi
