Embodiment 1

[0034] see Figure 1 to Figure 4 , a cell series module bracket according to an embodiment of the present invention, the cell series module bracket is a battery cell 4-series module bracket (4 single cells 40 are connected in series to form a battery module). It can be seen from the figure that the cell series module bracket mainly includes: a module bracket main body 10 and a module crimping cover 20 . Wherein, one end of the main body 10 of the module bracket is provided with a plurality of first tab welding platforms 11, and each first tab welding platform 11 is provided with a first tab welding through groove 111 on both sides, and the adjacent first tab welding platforms 11 A tab welding platform 11 is separated by a partition 112; the other end of the module support body 10 is provided with a second tab welding platform 12, and a plurality of second poles are provided on the second tab welding platform 12. The lug welding through groove 121, the two sides of the second ...

Embodiment 2

[0042] see Figure 5 to Figure 12 , a battery cell series module according to an embodiment of the present invention, specifically, the battery cell series module bracket is a battery cell 4-series module. It can be seen from the figure that the cell series module mainly includes: a cell series module bracket, positive and negative power lines 30 and multiple cells 40 .

[0043] Wherein, the battery cell series module bracket is the battery cell series module bracket in Embodiment 1; multiple battery cells 40 are stacked with different polarities (that is, the positive pole of one battery cell 40 is positively connected to the negative pole of the adjacent battery cell 40). Yes, its negative pole is opposite to the positive pole of the adjacent electric core 40); the first tabs 41 at one end of the multiple electric cores 40 protrude from the plurality of first tab welding slots 111 respectively, and are bent and welded in pairs Above the first lug welding platform 11; the se...

Abstract

The invention discloses a battery cell series connection module support, and a battery cell series connection module and an assembling method thereof. The battery cell series connection module supportcomprises: a module support main body, wherein one end of the module support main body is provided with first tab welding platforms, two sides of the first tab welding platforms are respectively provided with first tab welding through grooves, and a separator is arranged between the adjacent first tab welding platforms, and the other end of the module support main body is provide with a second tab welding platform which is provided with second tab welding through grooves, the two sides of the second tab welding platform are provided with lead-out tab welding platforms, one sides, far away from the second tab welding platform, of the lead-out tab welding platforms are provided with lead-out tab welding through grooves, and the height of the second tab welding platform is larger than that of these of the lead-out tab welding platforms; and a module wire pressing cover detachably covering the module support main body. The battery cell series connection module support solves the problem that the short circuit is easy to generate in the processing and later use processes due to the not enough insulation distance between a combined battery cell series connection point or the positive and negative welding points of the current hole punching module support.

Description

technical field [0001] The invention relates to the technical field of new energy batteries, in particular to a battery cell series module bracket suitable for single pit soft-packed batteries, a battery series module and an assembly method thereof. Background technique [0002] In the application of new energy batteries, the welding process of the battery needs to pay attention to the short-circuit protection of the edge sealing of the battery and the tabs. Especially the soft-packed single cell, due to the thin thickness of the soft-packed cell and the problem of single-hole design of the cell, it is easy to cause the distance between the series connection points to be too small. In the process, a short circuit is prone to occur, forming a great safety hazard. Contents of the invention [0003] The main purpose of the present invention is to provide a battery cell series module bracket, battery series module and its assembly method to solve the problem of battery cells ...
