The utility model has the advantages as follows:

(1) the middle waist module adopts a split structure of a left middle waist and a right middle waist, so that the whole middle waist structure is easier to realize in the manufacturing process, and the mold opening is simpler (if an integral structure is adopted, the heat dissipation structure in the middle waist is difficult to realize by the existing injection molding process);

(2) a plurality of partition plates are arranged inside the middle waist, so that when the battery cells are installed, only the single battery cells are required to be placed into the accommodating grooves formed by the partition plates one by one, and the assembly is more convenient and quicker;

(3) the design of the heat dissipation groove is beneficial to heat dissipation between the battery cores, and the material and the weight of the middle waist can be saved, so that the weight of the whole box body is reduced;

(4) the interval distribution has many ribs on two sides of baffle, and after holding tank was put into to electric core, one side laminating of electric core was at the rib upper surface, constitutes hollow heat dissipation wind channel with the side of electric core between the adjacent rib like this, has improved battery PACK's heat dispersion greatly.
