The first positioning portions 106 are distributed on the same side of the bracket 100 , and the first side of the electrical connection board 200 may be a long side of the electrical connection board 200 . For example, the first positioning group includes two first positioning portions 106, and one first positioning portion 106 is arranged adjacent to the first end of the same side of the bracket 100, and the other first positioning portion 106 is arranged adjacent to the second end of the same side of the bracket 100; the second positioning group includes two second positioning portions 208, and one second positioning portion 208 is arranged adjacent to the first end of the first side of the electrical connection board 200, and the other second positioning portion 208 is arranged adjacent to the second end of the first side of the electrical connection board 200.

The second side of the electrical connection board 200 is opposite to the first side, that is, the second side of the electrical connection board 200 is the other long side of the electrical connection board 200 . For example, the third positioning group includes two third positioning portions 108, and one third positioning portion 108 is arranged adjacent to the first end of the other side of the bracket 100, and the other third positioning portion 108 is arranged adjacent to the second end of the other side of the bracket 100; the fourth positioning group includes two fourth positioning portions 212, and one fourth positioning portion 212 is arranged adjacent to the first end of the second side of the electrical connection board 200, and the other fourth positioning portion 212 is arranged adjacent to the second end of the second side of the electrical connection board 200.

[0060] The guide member 114 and the bracket 100 may be an integrally formed structure. For example, the bracket 100 may be provided with two guide members 114, wherein one guide member 114 is provided adjacent to one stopper, and the other guide member 114 is provided adjacent to another stopper.

[0061] For example, Figure 7 and Figure 8As shown, the soft-pack battery group 400 includes two soft-pack battery cells 402, and the positive terminals and negative terminals of the two soft-pack battery cells 402 are respectively connected to the first connection terminal group 202, for example, by laser welding. The positive terminals and negative terminals of the two soft-pack battery cells 402 are respectively connected to the first connection terminal group 202. Further, the soft-pack battery cell 402 can be rotated along the guide member 114 by applying an external force to the soft-pack battery cell 402, thereby realizing the rotational assembly of the soft-pack battery cell 402.

[0062] In one example, if Figure 1 and Figure 2 As shown, the guide member 114 is provided with a guide surface 116 , and the guide surface 116 guides each soft-pack battery cell 402 to rotate.

[0063] For example, the positive terminal and negative terminal of the soft-pack battery cell 402 are respectively provided with corresponding electrode connecting sheets 404, wherein the positive terminal and negative terminal of the soft-pack battery cell 402 can be elastic metal sheets, such as nickel sheets.

[0064] An extension plate 406 is provided on the first end face of the soft-pack battery cell 402, and the electrode connecting piece 404 corresponding to the positive end and the electrode connecting piece 404 corresponding to the negative end of the soft-pack battery cell 402 are respectively provided on the extension plate 406, and the extension plate 406 is perpendicular to the first end face; a guide plate is also provided on the first end face of the soft-pack battery cell 402, and the guide plate is perpendicular to the first end face and the guide is perpendicular to the extension plate 406. Exemplarily, the guide plate and the extension plate 406 are an integrally formed structure. When the electrode connecting pieces 404 corresponding to the positive and negative terminals of the soft-pack battery cell 402 are connected to the first connecting terminal group 202, the guiding surface 116 of the guiding member 114 is parallel to the guiding plate of the soft-pack battery cell 402, and the guiding surface 116 of the guiding member 114 is adjacent to the guiding plate, and then by applying an external force to the soft-pack battery cell 402, the soft-pack battery cell 402 can be rotated along the guiding surface 116 of the guiding member 114, thereby realizing the rotational assembly of the soft-pack battery cell 402, and improving the convenience of assembling multiple soft-pack battery cell groups 400.

The electrode connecting piece 404 of each soft-pack battery cell 402 is respectively connected to the first connection terminal group 202 .

[0073] The positive terminal and the negative terminal of the soft-pack battery cell 402 are respectively provided with electrode connecting sheets 404 , and the electrode connecting sheets 404 may be elastic metal sheets.

[0074] An extension plate 406 is provided on the first end face of the soft-pack battery cell 402, and the electrode connecting piece 404 corresponding to the positive end and the electrode connecting piece 404 corresponding to the negative end of the soft-pack battery cell 402 are respectively arranged on the extension plate 406, and the extension plate 406 is perpendicular to the first end face, so that the electrode connecting piece 404 is spaced apart from the first end face of the soft-pack battery cell 402, thereby facilitating the connection of the electrode connecting piece 404 of the soft-pack battery cell 402 to the first connection terminal group 202, respectively, thereby improving the assembly convenience of the soft-pack battery cell 402. By connecting the first connection terminal group 202 and the second connection terminal group 204 in series or in parallel, each soft-pack battery cell 402 can be connected in series or in parallel to meet the use of high-power equipment. The second connection terminal group 204 of the electrical connection plate 200 corresponds to the first through hole group 102 of the bracket 100, so that the electrical load or external power supply can be directly connected to the second connection terminal group 204 through the first through hole group 102, thereby realizing electrical connection between the electrical load or external power supply and the soft-pack battery cell group 400, thereby simplifying the replacement assembly process of the soft-pack battery cell 402.

[0075] In one embodiment, Figure 5 and Figure 7 As shown, the soft-pack battery cell group 400 further includes a spacer 500 , which is disposed between the first end surface of the soft-pack battery cell 402 and the electrode connecting sheet 404 .

[0076] The spacer 500 may be EVA foam. The spacer 500 is used to insulate and isolate the electrode connecting sheet 404 from the first end face of the soft-pack battery cell 402. By arranging the spacer 500 between the first end face of the soft-pack battery cell 402 and the electrode connecting sheet 404, the electrode connecting sheet 404 can be prevented from scratching the soft-pack battery cell 402, thereby further improving the reliability of the soft-pack battery cell 402 and enhancing the protection of the soft-pack battery cell 402.

[0077] Exemplarily, a guide plate is further provided on the first end surface of the soft-pack battery cell 402, and the guide plate is perpendicular to the first end surface and is guided perpendicular to the extension plate 406. When the electrode connecting pieces 404 corresponding to the positive and negative ends of the soft-pack battery cell 402 are connected to the first connection terminal group 202, the guide surface 116 of the guide member 114 is parallel to the guide plate of the soft-pack battery cell 402, and the guide surface 116 of the guide member 114 is adjacent to the guide plate, and then by applying an external force to the soft-pack battery cell 402, the soft-pack battery cell 402 can be rotated along the guide surface 116 of the guide member 114, so as to realize the rotational assembly of the soft-pack battery cell 402, thereby improving the convenience of assembling a plurality of soft-pack battery cell groups 400.

[0078] It should be noted that the battery module may also include components such as label components, and a specific battery module may include more components than those described in the above embodiments, or combine certain components, or have a different arrangement of components.
