Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a novel split-type CCS acquisition module and energy storage battery cabinet. Background Technology

[0002] With the rapid development of the new energy industry, energy storage batteries are constantly being optimized and iterated to meet the demands of green and sustainable development. Traditional energy storage battery cabinets are typically designed with double-sided doors, but this design has certain limitations in terms of after-sales maintenance and product structure simplification. Therefore, energy storage battery cabinets are gradually evolving towards a single-sided door structure. This structural optimization facilitates after-sales operation and maintenance, while also reducing material and assembly costs through structural simplification.

[0003] In this evolution, the Battery Management Unit (BMU) of the energy storage battery module has been changed from being placed at both ends of the PACK to being centrally located at one end of the PACK. This layout adjustment improves the compactness of the internal structure and the rationality of the overall design, but it also brings new technical challenges, especially the electrical connection between the BMU and the cell acquisition system within the battery module, which is located far away. Traditional wiring methods not only increase space occupation but may also lead to a degradation in electrical performance, thereby affecting the safety and reliability of the energy storage system. Utility Model Content

[0039] like Figures 1 to 11 As shown, this utility model discloses a novel split-type CCS acquisition module, comprising:

[0040] A first integrated busbar 1 and a second integrated busbar 2 that can be assembled and connected with the first integrated busbar 1;

[0041] The first integrated busbar 1 includes a first bracket 11 and a first conductive bar 31 disposed on the first bracket 11, at least one first acquisition module 12, and a first protective cover plate 13. The first conductive bar 31 is mounted on the upper surface of the first bracket 11 and arranged along the extending direction of the first bracket 11. The first acquisition module 12 includes a first circuit board 421 and a first connector 511. The first circuit board 421 is disposed along the extending direction of the first bracket 11 and electrically connected to the first conductive bar 31 through a first conductive sheet 431. The first connector 511 is mounted on one end of the first circuit board 421 and electrically connected to the first circuit board 421. The first protective cover plate 13 covers the first bracket 11 and snaps into the first bracket 11, so that the first conductive bar 31 and the first acquisition module 12 are accommodated within the first protective cover plate 13.

[0042] The second integrated busbar 2 includes a second bracket 21 and a second conductive busbar 32 disposed on the second bracket 21, at least one second acquisition module 22, and a second protective cover plate 23. The second conductive busbar 32 is mounted on the upper surface of the second bracket 21 and arranged along the extension direction of the second bracket 21. The first acquisition module 12 includes a second circuit board 422 with an extension portion 41 and a second connector 512. The extension portion 41 has the same length as the first circuit board 421. The second circuit board 422 is disposed along the extension direction of the second bracket 21 and electrically connected to the second conductive busbar 32 through a second conductive sheet 432. The second connector 512 is mounted on the end of the extension portion 41 away from the second circuit board 422 and is electrically connected to the second circuit board 422. The second protective cover plate 23 covers the second bracket 21 and engages with the second bracket 21, so that the second conductive busbar 32 and the second acquisition module 22 are accommodated within the second protective cover plate 23.

[0043] The extension 41 in the second acquisition module 22 overlaps with the first circuit board 421 in the first acquisition module 12, and the extension 41 is accommodated in the first protective cover plate 13.

[0044] With the above structure, the novel split-type CCS acquisition module of this utility model adopts a modular design, including a first integrated busbar 1 and a second integrated busbar 2. The combination of the two solves the problem of electrical connection between the battery management unit system and the battery module located far away, and realizes efficient and stable electrical signal transmission. The first integrated busbar 1 consists of a first bracket 11, a first conductive bar 31, a first acquisition module 12, and a first protective cover plate 13. The first conductive bar 31 is installed on the upper surface of the first bracket 11 and is arranged along the extension direction of the bracket to provide an electrical connection path. The first circuit board 421 of the first acquisition module 12 is connected to the first conductive bar 31 through a first conductive sheet 431, and a first connector 511 is installed at one end for power input and output. The first protective cover plate 13 covers the first bracket 11 by snap-fit, completely encapsulating the first conductive bar 31 and the first acquisition module 12, and providing protection. The structure of the second integrated busbar 2 is similar to that of the first integrated busbar 1, including a second bracket 21, a second conductive bar 32, a second acquisition module 22, and a second protective cover plate 23. The difference is that the second acquisition module 22 has an extension 41, the length of which is the same as that of the first circuit board 421. This extension 41 overlaps with and is fixed to the first circuit board 421 of the first acquisition module 12 when the first integrated busbar 1 and the second integrated busbar 2 are combined, making the electrical connection of the overall structure more compact and reliable. The first protective cover 13 not only covers the components of the first integrated busbar 1 but also accommodates the overlapping extension 41, achieving overall encapsulation and protection.

[0045] The first connector 511 and the second connector 512 are located on the same side of the second bracket 21. As the opening method of the energy storage battery cabinet has evolved from double-sided to single-sided, the optimized position of the first connector 511 and the second connector 512 solves the problem of electrical connection between the battery management unit system and the battery module far away from it.

[0046] The first acquisition module 12 also includes a first reinforcing piece 521, which provides mechanical support to maintain the overall strength of the first circuit board 421 during local folding. The first reinforcing piece 521 and the first connector 511 are located at the same end of the first circuit board 421. When the first circuit board 421 is not folded, the interface of the first connector 511 faces the other end of the first circuit board 421. The first connector 511 is located on the upper surface of the first circuit board 421, and the first reinforcing piece is located on the lower surface of the first circuit board 421. When the area of ​​the first circuit board 421 containing the first reinforcing piece 521 is folded 180°, the interface direction of the first connector 511 changes accordingly in the opposite direction. Preferably, the first reinforcing piece 521 is located near the bend of the first circuit board 421, and a smooth chamfer is provided on the first reinforcing piece 521 to prevent the first circuit board 421 from contacting sharp corners. A temperature sensor 44 is also included on the first conductive sheet 431 and the second conductive sheet 432. The temperature sensor 44 can sense the temperature changes of the first conductive sheet 431 and the second conductive sheet 432 in real time, reflecting the operating status of the first conductive sheet 431 and the second conductive sheet 432 and the ambient temperature. The temperature sensor 44 is electrically connected to the first circuit board 421 or the second circuit board 422, enabling the first acquisition module 12 or the second acquisition module 22 to upload temperature data to the data processing unit on the first circuit board 421 or the second circuit board 422, realizing real-time data acquisition and processing. The first conductive sheet 431 and the second conductive sheet 432 are important channels for current transmission, and their temperature can directly reflect the current load, heat dissipation effect and abnormal conditions. Placing the temperature sensor 44 on the first conductive sheet 431 and the second conductive sheet 432 can accurately monitor the thermal conditions related to current transmission.

[0047] The first conductive sheet 431 and the second conductive sheet 432 are connected to the circuit board using an "S"-shaped structure. The "S"-shaped tear-resistant structure forms multiple bends on the first and second conductive sheets 431 and 432, preventing stress concentration and breakage when subjected to tension, bending, or vibration. Specifically, the "S"-shaped structure, by increasing the path length of the bending section, effectively disperses mechanical stress, preventing cracks or breakage of the first and second conductive sheets 431 and 432 under dynamic loads. The "S"-shaped structure provides the conductive sheets with a certain degree of flexibility and deformation margin, easily adapting to various layout requirements and installation positions of different sizes or angles during assembly, while avoiding mechanical damage caused by excessive stretching or compression. Especially under conditions of large temperature variations in the working environment, the first conductive sheet 431 or the second conductive sheet 432 may deform due to thermal expansion. The "S"-shaped design provides additional deformation buffer space for the first and second conductive sheets 431 and 432, preventing tearing or desoldering caused by expansion stress.

[0048] The first reinforcing piece 521 and the first circuit board 421 are respectively provided with positioning holes 6, the positions of which correspond to each other, serving as auxiliary positioning. After the first reinforcing piece 521 is folded, the positioning holes 6 on the first reinforcing piece 521 and the first circuit board 421 can be completely overlapped, ensuring the alignment accuracy and installation stability after folding. The first reinforcing piece 521 is connected to the first circuit board 421 by adhesive. After folding, the first reinforcing piece 521 is tightly attached to the back of the first circuit board 421. The positioning holes 6 allow the first reinforcing piece 521 and the first circuit board 421 to be quickly and accurately aligned in the folded position, simplifying the positioning process, reducing the time for manual adjustment, and significantly improving assembly efficiency.

[0049] The second acquisition module 22 includes a second reinforcing piece 522. The second reinforcing piece 522 and a second connector 512 are mounted on the extension 41 of the second acquisition module 22. The second connector 512 is mounted on the upper surface of the extension 41, and its interface direction is consistent with the interface direction of the first connector 511 in the first acquisition module 12 after being folded. The second reinforcing piece 522 is located on the lower surface of the extension 41. When the first acquisition module 12 and the second acquisition module 22 are assembled, the extension 41 of the second acquisition module 22 overlaps with the first circuit board 421 of the first acquisition module 12.

[0050] Furthermore, a fixing bracket 8 is provided on the first bracket 11 for fixing the second reinforcing piece 522 in the second acquisition module 22. The fixing bracket 8 is designed with rivet holes 71 to cooperate with the rivet posts 72 provided on the first bracket 11, forming a limiting and fixing mechanism. This ensures that after the second reinforcing piece 522 is fixed on the fixing bracket 8, it can be more securely installed on the first bracket 11, preventing loosening or displacement during operation. The first bracket 11 is provided with rivet posts 72 for limiting the position of the first conductive strip 31 and the fixing bracket 8. The rivet posts 72 provide a precise positioning function, enabling the first conductive strip 31 and the fixing bracket 8 to quickly find their preset positions during installation, while preventing positional displacement due to external forces. Preferably, the fixing bracket 8 is provided with a limiting part 81 for restricting the position of the second reinforcing piece 522, ensuring that the second reinforcing piece 522 can be accurately positioned and remain stable. The fixed bracket 8 also includes a snap-fit ​​part 82, which is a detachable fixing method. It provides a reliable connection through mechanical engagement and facilitates subsequent maintenance or replacement of the second reinforcing piece 522. The rivet holes 71 of the fixed bracket 8 allow the second reinforcing piece 522 to be securely installed on the first bracket 11. The second bracket 21 is also equipped with rivet posts 72 that limit the movement of the second conductive bar 32. The rivet posts 72 provide clear positioning for the first conductive bar 31, the second conductive bar 32, and the fixed bracket 8 during installation, making the installation process faster and more precise, reducing the time and error associated with manual adjustments.

[0051] The extension 41 is located above the first circuit board 421 in the first acquisition module 12 and can be connected to the first integrated busbar 1 by adhesive bonding, optimizing the module integration method and performance. The extension 41 makes the overall integration of the first acquisition module 12 and the second acquisition module 22 more compact, improving the flexibility of module design. The adhesive bonding method effectively reduces stress concentration caused by mechanical fixing, avoiding structural damage due to vibration or thermal expansion, thereby extending the module's service life.

[0052] This utility model also discloses an energy storage battery cabinet, which includes a cabinet body and a novel split-type CCS acquisition module. The novel split-type CCS acquisition module is installed in the cabinet body. The cabinet body has a door on one and only one side. The first connector 511 and the second connector 512 are arranged facing the door.

[0053] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
