Problems solved by technology

[0002] The cells of the CTP battery pack are placed in the inner cavity formed by the box body and the upper cover, and fixed by glue injection. In the related technology, after the glue is applied in the box, the cells are placed in the box one by one for bonding In the process of putting the battery into the box, it is easy to scratch the inner wall of the box and push the colloid to the bottom of the box, resulting in uneven distribution of the colloid and poor fixing effect of the battery, which seriously reduces the assembly quality of the battery pack

Abstract

The battery pack assembling process comprises the following steps: arranging pole columns of a plurality of battery cells downwards to form a battery cell group, buckling a box body downwards to the battery cell group, putting the battery cell group into a box, overturning the box body and the battery cell group, and injecting glue into a gap between the box body and the battery cell group, the battery pack is manufactured by the battery pack assembling process. According to the battery cell box, the battery cell group is put into the box in an inverted manner, and after the battery cell group is put into the box, the multiple battery cells are put into the box at the same time in a manner of arranging the multiple battery cells into the battery cell group and buckling the box body to the battery cell group, so that the efficiency of assembling the battery cells into the box body is improved; glue distribution is not affected in the process that the battery cells enter the box, glue is directly injected into the gap between the battery cell group and the box body, the gap between the battery cell group and the box body can be fully filled with glue, and glue distribution is more uniform.

Description

technical field [0001] The present application relates to the technical field of power batteries, in particular to a battery pack assembly process and a battery pack. Background technique [0002] The cells of the CTP battery pack are placed in the inner cavity formed by the box body and the upper cover, and fixed by glue injection. In the related technology, after the glue is applied in the box, the cells are placed in the box one by one for bonding In the process of putting the battery into the box, it is easy to scratch the inner wall of the box and push the colloid to the bottom of the box, resulting in uneven distribution of the colloid and poor fixing effect of the battery, which seriously reduces the assembly quality of the battery pack . Contents of the invention [0003] This application aims to solve at least one of the technical problems existing in the prior art. For this reason, the present application proposes a battery pack assembly process, which can redu...
