Abstract:

Provided in the present invention is a battery module. The battery module comprises: a plurality of batteries arranged side by side along a length direction, each battery including a top cover assembly, and the top cover assembly including a top cover sheet; and a FPC located in a height direction above the top cover sheets of all batteries. A fixing post is provided on the top cover sheet of at least one of the batteries, and the FPC is provided with a positioning hole at the position corresponding to the battery provided with the fixing post. The fixing post is provided with: a rod portion, which is received in the positioning hole of the FPC and has one end fixed to the top cover sheet; and a cover portion, which is connected to the other end of the rod portion, covers the positioning hole and is fixed to the FPC, thereby fixing the FPC to the corresponding battery. The FPC fixing method for the battery module is stable and effective, improves FPC fixing reliability, facilitates automatic production and reduces cost. Compared with the pasting method in the prior art, the FPC fixing method of the present invention has a wider application range, avoids situations unfavorable for production, such as wrinkles formed during manual pasting and the like, and facilitates the improvement of production efficiency.
