Abstract

The box body comprises a plurality of side plates, at least one side plate is a preset side plate, and the preset side plate comprises a plate body, a plurality of side plates and a plurality of side plates, and a plurality of support ribs, the plurality of support ribs are arranged on the inner wall of the plate body, the plurality of support ribs are distributed at intervals along the height direction of the box body, and the plurality of support ribs are respectively used for supporting and fixing a plurality of battery modules which are sequentially arranged along the height direction of the box body. According to the preset side plate provided by the invention, by providing the plurality of supporting ribs which are arranged at intervals along the height direction of the box body, the plurality of battery modules which are sequentially arranged along the height direction of the box body are supported and fixed, so that a supporting plate in related technologies is omitted, the structural complexity and the cost of the battery pack can be reduced, and the battery pack is convenient to use. The overall weight of the battery pack is reduced, occupation of the space in the battery pack is reduced, the space utilization rate in the battery pack is improved, and the battery pack can meet the light-weight development requirement.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a box body for a battery pack and a battery pack with the same. Background technique [0002] In the double-layer battery module in the related art, in order to realize the support and fixation of the upper battery module and the lower battery module in the box, the following methods are usually adopted. One method is to use a support plate with feet, and pass the support plate through A plurality of feet are supported on the inner bottom wall of the box. Another way is to use a support plate without feet, and fix the support plate to the inner wall of the box by bolts or the like. On the convex rib, or be fixed on the supporting base on the bottom wall of the box. Therefore, in the above-mentioned several ways, the bottom space for accommodating the lower battery module can be set up between the support plate and the inner bottom wall of the box, and then the support plate pr...
