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 ...

Examples

Embodiment 1

[0046] Figure 1 to Figure 7 It shows a specific application example of the battery connection bracket of the present application in a battery module, the battery module is a cylindrical lithium-ion battery module, which is the same as the traditional battery module, and also includes a battery connection Bracket (also known as battery bracket in the industry), the battery connection bracket is formed with numerous battery insertion holes distributed in a matrix, each battery insertion hole is embedded with a battery series piece 1, and each battery insertion hole A cylindrical lithium-ion battery cell 2 is inserted in each of them. Specifically, in this embodiment, the negative terminal of the battery cell 2 is inserted into the battery insertion hole of the battery connection bracket, and is directly contacted (not welded) with the battery series piece 1 in the battery insertion hole.

[0047] The key improvement of this embodiment is that the above-mentioned battery connec...

Embodiment 2

[0069] Figure 8 to Figure 14 It shows a specific application example of the battery connection bracket of the present application in another battery module. The structure of the battery module in this example is basically the same as that of the battery module in Implementation 1. The main differences are:

[0070] First, in this embodiment, the positive end of each battery cell 2 (instead of the negative end of the battery cell in Embodiment 1) is inserted in the battery insertion hole of the battery connection bracket, and is connected to the battery insertion hole. The battery series sheet 1 is welded and connected (rather than the separate contact connection in the first embodiment), specifically, the positive terminal of the battery cell 2 is welded to the protrusion 102a on the bottom sheet 102 of the battery series sheet 1 .

[0071] Second, in this embodiment, the metal parallel bar 4 no longer adopts the integrated structure in Embodiment 1, but is formed by butting ...
