[0001] This utility model relates to the field of energy storage technology, and in particular to a battery module. Background Technology

[0002] With the rapid development of new energy technologies, large-scale energy storage systems are playing an increasingly important role in areas such as power peak shaving and renewable energy grid connection. As the core equipment of an energy storage system, the energy storage battery module typically contains multiple battery packs to achieve large-capacity energy storage. In existing technologies, the connection between the battery packs and the battery management system (BMS) slave board is usually achieved using screws. During slave board installation, the mounting holes on the slave board need to be aligned with the corresponding mounting holes on the connector. Due to the large number of battery packs within the energy storage battery module, aligning them one by one is time-consuming. Utility Model Content

[0003] The main purpose of this utility model is to provide a battery module to solve the above-mentioned technical problems.

[0004] The objective of this utility model can be achieved by adopting the following technical solution:

[0013] This also includes:

[0014] A plurality of battery packs are spaced apart along the length direction;

[0015] A partition is disposed between two adjacent battery packs, and the partition has ventilation holes extending through it along its width.

[0016] The partition has limiting portions on both the left and right sides. The limiting portions form a first limiting space above the partition and a second limiting space below the partition.

Detailed Implementation

[0026] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0027] like Figures 1-4 As shown, the battery module provided in this embodiment is suitable for use inside an energy storage battery module as an energy storage unit. The battery module includes a battery pack 100, one end of which is provided with a connector 200; a slave plate 300, which is electrically connected to the connector 200; and a positioning structure, which includes a protrusion 210 disposed on the connector 200 and a positioning hole 310 disposed through the slave plate 300. The protrusion 210 and the positioning hole 310 are inserted and engaged to achieve positioning of the slave plate 300 relative to the connector 200.

[0028] In this embodiment, the connector 200 is electrically connected to the top surface of the battery pack 100, and the slave plate 300 is electrically connected to the battery pack 100 by cooperating with the connector 200. The protrusion 210 is inserted into the positioning hole 310, which enables the slave plate 300 to be quickly positioned relative to the connector 200.

[0029] Specifically, the protrusion 210 is provided on the front side of the connector 200. When installing the slave board 300, initial positioning and connection can be quickly completed by simply aligning the positioning hole 310 of the slave board 300 with the protrusion 210 on the connector 200. This extended protrusion 210 guides the installation position of the slave board 300, ensuring accurate connection positioning. The slave board 300, through its cooperation with the connector 200, can obtain the real-time status of the battery pack 100.

[0030] Through the design of the positioning structure described above, this embodiment achieves rapid and accurate docking between the connector 200 and the slave board 300. This design improves assembly efficiency and effectively solves the problems of inconvenient connection and inaccurate positioning between the connector 200 and the slave board 300 in the prior art.

[0031] In this embodiment, the slave board 300 is used as a component of the battery management system and works in conjunction with the main board of the battery management system (not shown in the figure).

[0032] In one embodiment, the protrusion 210 is a columnar structure, and the cross section of the columnar structure perpendicular to the insertion direction from the plate 300 is non-circular. The shape of the positioning hole 310 is adapted to the protrusion 210.

[0033] In this embodiment, as Figure 1As shown, the vertical cross-section of the protrusion 210 (i.e., the cross-section perpendicular to the insertion direction of the plate 300) is non-circular. This non-circular cross-section design provides a clear directionality, effectively preventing misalignment during installation. Because the columnar structure uses a non-circular design on the cross-section perpendicular to the insertion direction, and the shape of the positioning hole 310 matches the protrusion 210, insertion can only be successfully completed when the protrusion 210 and the positioning hole 310 are perfectly aligned. This design effectively avoids directional errors that may occur during installation.

[0034] Furthermore, this columnar structure design not only ensures the correct insertion direction but also guarantees the precise relative position between the connector 200 and the slave board 300. When the protrusion 210 is fully inserted into the positioning hole 310, the non-circular mating structure between them effectively prevents relative rotation, ensuring connection stability.

[0035] In one specific embodiment, the cross-section of the protrusion 210 perpendicular to the insertion direction from the plate 300 is elliptical. Correspondingly, the shape of the positioning hole 310 on the plate 300 is adapted to the protrusion 210, that is, the vertical cross-section of the positioning hole 310 is also elliptical.

[0036] This elliptical design is a specific implementation of the aforementioned non-circular cross-section. The ellipse has a major axis and a minor axis; this difference in axial dimensions allows for better directional positioning. When installing from plate 300, the major axis of the positioning hole 310 must be aligned with the major axis of the protrusion 210; otherwise, insertion cannot be completed. This mandatory alignment requirement further improves the positioning accuracy during installation.

[0037] Meanwhile, the elliptical structure has a smooth contour compared to other non-circular structures, which not only ensures the anti-rotation effect but also facilitates the insertion of the protrusion 210 into the positioning hole 310, thus improving the convenience of assembly.

[0038] In other embodiments, the protrusion 210 is a hexagonal columnar structure (not shown in the figures), with a regular hexagonal vertical cross-section. The positioning hole 310 on the plate 300 is correspondingly designed as a hexagon. This structural design also enables quick docking between the plate 300 and the protrusion 210.

[0039] In one embodiment, the positioning hole 310 is provided in the middle of the slave plate 300.

[0040] In this embodiment, as Figure 1As shown, board 300 can be roughly divided into a central area and an edge area, with positioning holes 310 located in the central area. Besides the positioning holes 310, circuit traces also need to be routed on board 300. Positioning the positioning holes 310 in the central area provides ample space for circuit traces in the edge area. Furthermore, this centered design reduces positioning deviations during installation and improves assembly accuracy.

[0041] In a practical implementation, board 300 is a cuboid-shaped circuit board with opposing front and rear surfaces. Positioning holes 310 penetrate both the front and rear surfaces. The dimensions of board 300 in the length and height directions are significantly larger than its thickness direction.

[0042] In one embodiment, a fixing hole 220 is provided through the corner of the connector 200, and a mounting hole 320 is provided through the corresponding corner of the plate 300. The mounting hole 320 and the corresponding fixing hole 220 are connected by fasteners.

[0043] In this embodiment, as Figure 2 As shown, a fixing hole 220 is provided through the corner of the connector 200, and a mounting hole 320 is correspondingly provided through the corner of the slave plate 300. After the slave plate 300 completes its initial positioning through the cooperation of the protrusion 210 and the positioning hole 310, a fastener (not shown in the figure) can be used to pass through the mounting hole 320 and the fixing hole 220 in sequence to achieve a fixed connection between the slave plate 300 and the connector 200.

[0044] Specifically, connector 200 has four corners, with at least two corners having through-holes 220. Correspondingly, slave plate 300 has four corners, with at least two corners having through-holes 320. When slave plate 300 approaches connector 200, fasteners such as screws can be sequentially passed through the interconnected mounting holes 320 and fixing holes 220 to achieve a secure connection between slave plate 300 and connector 200. This fixing structure design, based on achieving quick alignment of protrusion 210 with positioning hole 310, further ensures the reliability of the connection through secondary fixing with fasteners.

[0045] In one embodiment, the battery module further includes a plurality of battery packs 100, which are spaced apart along the length direction; and a partition 500, which is disposed between two adjacent battery packs 100, and a ventilation hole 510 is provided through the partition 500 along the width direction.

[0046] In this embodiment, as Figure 1 As shown, the battery module includes two battery packs 100, which are spaced apart along the length. A partition 500 is provided between them for supporting and isolating the battery packs 100.

[0047] Specifically, the partition 500 has ventilation holes 510 extending through it along its width. These through ventilation holes 510 form a vertically continuous ventilation channel, which facilitates the natural flow of hot air around the battery pack 100. This ventilation design avoids localized heat accumulation between adjacent battery packs 100 due to their close proximity.

[0048] In one embodiment, limiting portions 520 are provided on both the left and right sides of the partition 500. The limiting portions 520 form a first limiting space 521 above the partition 500 and a second limiting space 522 below the partition 500. The battery pack 100 located above and below the partition 500 is respectively accommodated in the first limiting space 521 and the second limiting space 522.

[0049] In this embodiment, as Figure 3 and Figure 4 As shown, limiting portions 520 are provided on both the left and right sides of the partition 500. These limiting portions 520 form a first limiting space 521 above the partition 500 and a second limiting space 522 below the partition 500. The battery pack 100 located above the partition 500 is housed within the first limiting space 521, and the battery pack 100 located below the partition 500 is housed within the second limiting space 522.

[0050] Specifically, the partition 500 is a rectangular plate structure with limiting portions 520 at each of its four corners. Each limiting portion 520 is a vertical plate structure, with its top end higher than the top of the partition 500 and its bottom end lower than the bottom of the partition 500. Thus, the two opposing limiting portions 520 can form a first limiting space 521 and a second limiting space 522 distributed vertically.

[0051] When the battery pack 100 is installed, the battery pack 100 above the partition 500 is located within the first limiting space 521 and is restricted by the left and right limiting parts 520, preventing it from shifting left or right. Similarly, the battery pack 100 below the partition 500 is located within the second limiting space 522 and is also restricted to a predetermined position by the limiting parts 520.

[0052] This limiting structure design, by setting limiting parts 520 on both sides of the partition 500, effectively prevents the battery pack 100 from moving left and right, and improves the overall stability of the battery module after it is assembled into the energy storage battery module.

[0053] In one embodiment, a wire harness fastener 600 is provided on the top of the partition 500.

[0054] In this embodiment, as Figure 3As shown, a wire harness fixing member 600 is provided on the top of the partition 500 to fix and organize the wiring around the battery pack 100. Since the partition 500 serves as a support structure between adjacent battery packs 100, providing a wire harness fixing member 600 on its top can make full use of the existing structural space.

[0055] In one specific embodiment, the wire harness fixing component 600 adopts a C-shaped snap-fit ​​structure. The inner cavity size of the C-shaped snap-fit ​​is adapted to the outer diameter of the wire harness to be fixed, and the opening width is slightly smaller than the diameter of the wire harness. The wire harness is fixed by the elastic deformation of the material. Here, the wire harness to be fixed refers to multiple wire harnesses clustered together.

[0056] During use, the operator can insert the open side of the wire harness fixing member 600 into the wire harness fixing member 600. During the insertion process, the wire harness fixing member 600 will deform to facilitate the insertion of the wire harness; when the wire harness is fully inserted into the inner cavity of the wire harness fixing member 600, the wire harness fixing member 600 will spring back and firmly fix the wire harness in its inner cavity.

[0057] In one embodiment, a fixing plate 400 is connected between the slave plates 300 corresponding to two adjacent battery packs 100. The fixing plate 400 includes a first wing plate 410 and a second wing plate 420 that are connected to each other. The first wing plate 410 is fixedly connected to the upper slave plate 300, and the second wing plate 420 is fixedly connected to the lower slave plate 300.

[0058] In this embodiment, as Figure 1 As shown, in order to maintain the relative position stability between the slave plates 300 corresponding to adjacent battery packs 100, a fixing plate 400 is provided between adjacent slave plates 300. The fixing plate 400 includes a first wing plate 410 and a second wing plate 420 connected to each other, wherein the first wing plate 410 is fixedly connected to the upper slave plate 300, and the second wing plate 420 is fixedly connected to the lower slave plate 300.

[0059] Specifically, the first wing plate 410 and the second wing plate 420 can be fixedly connected to the corresponding slave plate 300 using fasteners such as screws and rivets. During actual installation, two or more slave plates 300 can be pre-connected into a whole using the fixing plate 400, and then positioned on top of the corresponding battery pack 100 in one go. This assembly method improves the efficiency of installing the slave plates 300 and reduces the positioning time when installing each slave plate 300 individually.

[0060] In summary, this embodiment achieves rapid positioning and assembly between the connector 200 and the slave plate 300 by providing a protrusion 210 on the connector 200 of the battery pack 100 and a positioning hole 310 on the slave plate 300 that mates with the protrusion 210. This positioning structure not only ensures accurate docking between the connector 200 and the slave plate 300 but also prevents relative rotation after docking, improving connection stability. Furthermore, this embodiment employs a design using a fixing plate 400 to connect adjacent slave plates 300, effectively maintaining the relative positional stability between adjacent slave plates 300. Another advantage of this design is that multiple slave plates 300 can be pre-assembled into a single component, thereby improving installation efficiency and reducing the installation and positioning time for a single slave plate 300.

Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
