[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-2 The present application proposes a module end plate, characterized in that it includes an end plate body 1, a BMS slave plate 2, and a base 3.

[0031] like Figure 1-2 As shown, a placement groove 11 is provided at one end of the end plate body 1; the BMS slave plate 2 is placed in the placement groove 11; and the base 3 is placed on one end of the end plate body 1 corresponding to the placement groove 11.

[0032] Specifically, the end plate body 1 is the main structural component of the module end plate, used to fix the battery cells, provide structural support, and protect the battery cells from external impacts; the BMS slave board 2 is used to collect module information and integrates it in the placement slot 11 of the end plate body 1, eliminating the need for special brackets or other components for fixing the BMS in the battery pack, thus improving structural compactness and battery pack energy density; the base 3 is used to fix the output terminals of the battery; integrating the BMS slave board 2 and the base 3 on the end plate body 1, and placing the base 3 and the BMS slave board 2 at the same end of the end plate body 1, reduces the types of materials, lowers costs, and achieves functional integration, improving integration and space utilization.

[0033] In some embodiments, such as Figure 1-2 As shown, the base 3 includes a mounting base 31 and a threaded sleeve 32. The mounting base 31 is located on one end of the end plate body 1 opposite the placement groove 11, and the mounting base 31 has an output stage opening 33 for the battery. The threaded sleeve 32 is fixedly installed in the output stage opening 33.

[0034] Specifically, the structure of the base 3 has been further optimized. The battery output stage is fixed by the mounting base 31 and the threaded sleeve 32, providing a stable mounting structure for the battery output pole. This also enhances the versatility and compatibility of the module, further improving the integration and reliability of the module.

[0035] In some embodiments, such as Figure 2 As shown, the mounting base 31 includes a horizontal plate 311 and an insertion block 312. The horizontal plate 311 is disposed on one end of the end plate body 1 corresponding to the placement groove 11. The insertion block 312 is disposed on one side of the horizontal plate 311 corresponding to the end plate body 1. The end plate body 1 has an insertion groove 12 for insertion of the insertion block 312. A limiting groove 313 is provided on the side wall of the insertion block 312. A limiting block 13 is provided in the insertion groove 12 corresponding to the limiting groove 313.

[0036] Specifically, the installation of the insert block 312 and the insert groove 12 achieves the fixation between the mounting base 31 and the end plate body 1, reducing the reliance on fasteners such as screws during installation, lowering production costs, and improving structural stability. Of course, the installation of the mounting base 31 can also be achieved by injection molding. By pickling the inner surface of the insert groove 12 to form nanopores, it can be injected into the insert groove 12. The nanopores can better bond the injection molding material with the end plate body 1.

[0037] The thickness of the horizontal plate 311 and the insert block 312 is adapted to the thickness of the end plate body 1, making the entire end plate structure more compact and coordinated; reducing structural instability or stress concentration caused by thickness differences, improving the overall structural strength and stability of the end plate, enhancing the overall aesthetics of the end plate, and facilitating assembly with other components; at the same time, it further improves the space utilization of the module and indirectly increases the energy density of the battery pack.

[0038] In some embodiments, such as Figure 2 The end plate body 1 has a collection interface 14 for the BMS to extend from the interface of the plate 2 at the corresponding placement groove 11, and the base 3 has a clearance hole 301 corresponding to the collection interface 14.

[0039] Specifically, the end of the end plate body 1 is provided with a data acquisition interface 14 at the corresponding placement slot 11, which is used for the BMS to extend from the interface of the board 2 to collect module information. This further optimizes the functional layout of the module end plate. At the same time, the setting of the clearance hole 301 ensures that the interface of the BMS can extend smoothly and connect to external devices, while avoiding interference of the base 3 with the data acquisition interface 14. This not only improves the functionality and reliability of the module, but also further enhances the space utilization and ensures the overall compactness of the module structure.

[0040] In some embodiments, such as Figure 2 As shown, the end plate body 1 also includes a BMS slave plate housing 15, which can be covered on the placement groove 11.

[0041] The BMS slave board housing 15 provides additional physical protection for the BMS slave board 2, preventing external factors such as dust and moisture from corroding it, thereby extending its service life and improving the module's reliability and stability. At the same time, the design of the BMS slave board housing 15 also enhances the overall aesthetics of the module, making it more suitable for use in various complex environments. The housing is closed using a conventional method found in existing technologies.

[0042] In some embodiments, the base 3 is made of insulating material, which further optimizes the safety performance of the module end plate and can effectively prevent short circuits between the battery output terminal and surrounding components, thereby significantly improving the safety of the module.
