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 proces

Embodiment 1

[0037] Figure 1 to Figure 4 A specific application example of the battery clamp of the present application in a battery module is shown, the battery module is a cylindrical lithium-ion battery module, which is the same as the traditional battery module, and also includes a battery clamp ( It is also called battery connection bracket in the industry), and the battery fixture is formed with many battery insertion holes distributed in a matrix, each battery insertion hole is embedded with a battery series piece 1, and each battery insertion hole is A cylindrical lithium-ion battery cell 2 is inserted. Specifically, in this embodiment, the negative terminal of the battery cell 2 is inserted into the battery insertion hole of the battery fixture, and is connected to the battery series piece 1 in the battery insertion hole.

[0038] The key improvement of this embodiment is that the above-mentioned battery clamp adopts a new structural form, such as figure 1 , which is mainly com...

Embodiment 2

[0051] Figure 5 to Figure 7 It shows a specific application example in which the battery clamp of this application is applied to another battery module. The structure of the battery module in this embodiment is basically the same as that of the battery module in Embodiment 1. The main difference lies in the following points: point:

[0052] First, the structural form of the conductive support 4 in the present embodiment is different from that of the conductive support in Embodiment 1. The conductive support 4 in this example is a piece of which is provided with some through holes (these through holes constitute the said conductive support holes) The aluminum plate is not formed by arranging multiple metal tubes together and fixing them by welding or sintering. The conductive bracket 4 can be cast from aluminum. Compared with the first embodiment, the conductive support 4 with the structure of the present embodiment has stronger integrity and higher structural strength. The...

Abstract

The invention discloses a battery fixture for a battery module. A plurality of battery jacking holes for jacking battery monomers are formed in the battery fixture, the battery fixture comprises an insulating bracket located on the lower layer and a conducting bracket located on the upper layer, the insulating bracket and the conducting bracket are closely arranged and are mutually fixed, a plurality of insulating bracket holes are formed in the conducting bracket, a plurality of conducting bracket holes are formed in the conducting bracket, and the insulating bracket holes and the conducting bracket holes form the battery jacking holes together. This battery module structure is compact and stable, convenient to assemble and good in heat dissipation, and the traditional parallel network structure is omitted.

Description

technical field [0001] The present application relates to the field of battery technology, in particular to a battery clamp used to connect multiple 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 fixture made of fully insulating material with numerous battery insertion holes, a large number of battery series sheets embedded in each battery insertion hole, and embedded in each battery insertion hole at the same time. A sheet of parallel network connected in contact with each battery series sheet, respectively inserted in each battery insertion hole and connected (directly contacted or welded) to the corresponding battery series sheet. In actual ...
