The battery connection support is compact and stable in structure and convenient to assemble and has excellent conducting ability and heat dissipation ability.

Description

technical field [0001] The present application relates to the field of battery technology, and in particular to a battery connection bracket, which is used to connect a plurality of battery cells to form a battery module. Background technique [0002] Lithium-ion rechargeable battery is currently the battery with the highest specific energy and the longest service life. Its technology has matured and its production volume is huge, and it has entered various fields of people's lives. Existing cylindrical lithium-ion battery modules generally include a battery connection bracket made of fully insulating material with numerous battery insertion holes on it, a large number of battery series slices embedded in each battery insertion hole, and embedded in each battery insertion hole at the same time. A sheet of parallel network connected in the hole and in contact with each battery series sheet, and a plurality of battery cells respectively inserted in each battery insertion hole ...

AI Technical Summary

Problems solved by technology

Moreover, the components welded with connecting pieces are loose, difficult to move during operation, and large parts are more difficult to process, so they are not suitable for mechanized operations.

[0008] The method of using a spring piece (series piece with a spring claw) removes the negative electrode welding, but it is very troublesome to expand outward with the dovetail and dovetail groove, and the heat dissipation is not very good

Thermal jacket heat pipes and thermal paste work well for heat dissipation, but these add-ons serve no purpose other than temperature regulation, increasing cost and complexity

The multi-hole parallel frame has good electrical conductivity and good heat dissipation, but dozens of holes are stamped and stretched at the same time, which is difficult to process

Moreover, due to structural constraints, the elastic claws are very short, so the elastic force is difficult to control, and the inserted battery is also prone to skew

[0009] Although the parallel network can realize the parallel connection of each battery, it needs to be welded and fixed with the battery series piece during assembly, which is difficult to assemble

In addition, although the parallel connection is in contact with the battery cells, it can absorb and transfer the heat of the battery to a certain extent, but because the parallel connection is very thin, its heat transfer speed is very slow

Moreover, the parallel connection is usually embedded in the battery connection bracket, which is difficult to directly connect with the external heat dissipation mechanism and cannot dissipate heat
