Abstract

The invention provides a battery module cell repair method and apparatus, and relates to the technical field of manufacturing of a battery pack. When a cell in the battery module needs to be replaced,only a fixed plate and a current collecting plate in the corresponding positions of the target cell which needs to be replaced are removed, then a new cell is replaced, and finally, connection between the new cell and a current collecting plate is completed, without dismantling the battery module. The repair method of the whole battery module is simple, the operation process is simple and convenient, damage to the battery module structure is avoided, and the maintenance cost and maintenance difficulty of the battery module are lowered.

Description

technical field [0001] The invention relates to the technical field of battery pack manufacturing, in particular to a method and device for repairing battery cells in a battery module. Background technique [0002] The battery module can be used as the power battery of the electric vehicle to provide electric energy for the electric vehicle. During use, individual cells in the battery module may be damaged, and the damaged cells need to be replaced at this time. When a damaged cell needs to be replaced, the structure of the entire module needs to be dismantled. Such a cell replacement method is very cumbersome. In addition, during the module removal process, it is easy to cause damage to the battery cells, and even cause the entire module to be scrapped, which increases a large amount of maintenance workload and increases the maintenance cost of the battery module. Contents of the invention [0003] In view of this, the present invention provides a battery module cell r...
