Description

Technical Field

[0001] This application relates to the field of energy storage system technology, and in particular to a BMS component mounting structure for an energy storage device. Background Technology

[0002] With the rapid development of energy storage systems, especially in the fields of electric vehicles and grid dispatch, energy storage PACKs (battery packs) are facing increasingly higher performance and reliability requirements as a key technology. The Battery Management System (BMS), as the core component of an energy storage system, is responsible for monitoring battery status and ensuring safe battery operation. The assembly and maintenance of BMS components are crucial to the stability and economy of energy storage systems. However, existing BMS component assembly and maintenance technologies face a series of problems.

[0003] First, the traditional BMS module assembly process is complex and time-consuming. Due to the multiple installation steps and numerous screws required, the assembly process is not only lengthy but also prone to operational errors or component damage. Second, if an existing BMS module fails, the entire energy storage PACK typically needs to be replaced, rather than just the BMS module itself. Because the BMS module is tightly integrated with other battery components, replacement requires the disassembly of numerous parts, making the process cumbersome, time-consuming, and prone to damaging other components during disassembly. Furthermore, existing BMS modules are susceptible to impacts or scratches during disassembly or assembly, leading to component damage and increasing the difficulty and cost of maintenance and replacement. These problems are particularly pronounced in energy storage systems requiring frequent maintenance, reducing system efficiency and impacting economic benefits.

[0004] Therefore, designing a solution that enables rapid assembly and disassembly of BMS components, reduces maintenance costs, and improves system reliability has become a key issue that current energy storage technology urgently needs to address. Utility Model Content

[0005] To address the problems of complex assembly and difficult replacement of BMS components in existing technologies, this application provides a BMS component installation structure for energy storage devices.

[0006] The BMS component mounting structure for an energy storage device provided in this application adopts the following technical solution:

[0007] A BMS component mounting structure for an energy storage device includes:

[0008] The enclosure has a mounting cavity and an openable / closable cover.

[0009] BMS assembly, including a protective housing and BMS components removably installed within the protective housing;

[0010] A fastener is used to detachably fix the protective housing to the mounting cavity;

[0011] The limiting component has a limiting state and an unlocking state; when in the limiting state, the limiting component and the fixing component work together to limit and fix the protective shell in the mounting cavity; when in the unlocking state, the protective shell can move relative to the mounting cavity and disengage from the limiting state.

[0012] By adopting the above technical solution, the synergistic effect of the protective shell, limiting components, and fixing components enables the stable installation and convenient disassembly of BMS components, thereby simplifying the process of installing, maintaining, and replacing BMS components. Operators can easily disassemble the BMS components for repair or component replacement by simply adjusting the limiting components to the unlocked state, without having to replace the entire energy storage device, thus reducing maintenance and replacement costs. At the same time, the protective shell, with the cooperation of the limiting components and fixing components, can be firmly fixed in the installation cavity, ensuring the stability and safety of the equipment during operation, preventing equipment failure due to loosening or displacement, and improving system reliability. This design not only improves the maintainability of the equipment and shortens maintenance time, but also improves system reliability, extends equipment lifespan, and optimizes the overall performance of the energy storage device.

[0013] In one specific implementation, a fixing plate is provided inside the mounting cavity, and the fixing element includes a fixing screw, which passes through the protective housing and is inserted into the fixing plate for threaded connection.

[0014] By adopting the above technical solution, the protective shell can be firmly fixed in the installation cavity by using the threaded connection of fixing screws and fixing plates, ensuring the stability of the equipment in the working state; at the same time, the installation and disassembly process is simple, avoiding the traditional complicated installation steps, reducing the difficulty and time of manual operation, and improving work efficiency.

[0015] In one specific implementation, the fixing screw is a single screw.

[0016] By adopting the above technical solution and using a single fixing screw design, the number of screws is reduced, and the installation and disassembly steps are simplified. When disassembling, only one screw needs to be loosened to easily remove the protective shell. The entire installation process is faster and more convenient, thereby reducing the complexity and time cost of operation.

[0017] In one specific implementation, the limiting member includes a limiting hole on the protective housing and a snap-fit ​​screw on the fixing plate. The limiting hole is hung on the snap-fit ​​screw. The limiting hole includes a limiting section and an operating section that communicate with each other. The limiting hole abuts against and is fixed to the snap-fit ​​screw through the limiting section. The limiting hole can enter or disengage from the snap-fit ​​screw through the operating section.

[0018] By adopting the above technical solution, the installation method of the limiting hole and the snap-fit ​​screw makes the installation process simple and easy. After the limiting hole enters the snap-fit ​​screw through the operating section, the protective shell is fixed to the limiting section by moving downward. The operation is intuitive and quick. Moreover, the abutting fixation between the limiting section and the snap-fit ​​screw can ensure the stability of the protective shell after installation. During disassembly, the protective shell moves upward to disengage the operating section of the limiting hole from the snap-fit ​​screw, simplifying the disassembly process and reducing disassembly time. Furthermore, the limiting hole will only disengage from the snap-fit ​​screw when the protective shell moves upward, thereby improving the safety of loading and unloading.

[0019] In one specific implementation, the aperture of the operating section is larger than the head diameter of the snap-fit ​​screw; the aperture of the limiting section is smaller than the head diameter of the snap-fit ​​screw, and the aperture of the limiting section is greater than or equal to the screw diameter of the snap-fit ​​screw.

[0020] By adopting the above technical solution, the diameter of the limiting section hole is smaller than that of the snap-fit ​​screw head and fits tightly with the screw rod part. Therefore, after installation, the protective shell can be stably fixed in position without loosening or slipping, thereby increasing the safety and reliability of the system. By using the limiting section hole diameter to be greater than or equal to the screw rod diameter, the limiting hole can smoothly enter or disengage from the snap-fit ​​screw during installation and disassembly, achieving the effect of quick assembly and disassembly.

[0021] In one specific implementation, the protective housing includes a base and an upper shell, the BMS components are installed in the receiving space formed by the upper shell and the base, and the base and the upper shell are detachably connected by connecting screws.

[0022] By adopting the above technical solutions, the design of the protective housing, through the tight fit between the base and the upper shell, can ensure the stability of the BMS components and avoid damage or displacement caused by external impacts or vibrations; the design of the connecting screws can provide effective fixing, ensuring the stability and safety of the protective housing during operation and avoiding the risk of loosening or falling off.

[0023] In one specific implementation, the upper shell is provided with an operating handle.

[0024] By adopting the above technical solution and utilizing the design of the operating handle, users can quickly lift, move, or adjust the BMS component during installation and disassembly, thereby improving the ease of operation of the entire BMS component and making the whole process more efficient.

[0025] In one specific implementation, the upper shell is provided with an observation hole.

[0026] By adopting the above technical solution, the observation hole allows users to directly observe the status indicator lights on the BMS components without disassembling the protective housing. This enables convenient and quick inspection of the health status of the BMS components without opening the protective housing, enhancing the ease of use and maintainability of the equipment, thereby saving maintenance time and improving operational efficiency.

[0027] In one specific implementation, the cover plate is detachably fixed to the housing by mounting screws.

[0028] By adopting the above technical solution, the cover plate is easy to remove by fixing with screws. If it is necessary to inspect the energy storage equipment or replace the BMS components, the operator only needs to remove the screws to easily access the inside of the enclosure and quickly perform the required operations. In addition, the cover plate is designed to seal the enclosure, ensuring that the energy storage equipment has good protection performance during operation.

[0029] In summary, the beneficial technical effects of this application are as follows: By employing a protective housing, limiting components, fixing components, and other supporting designs, the BMS component can be stably installed and easily disassembled. First, the synergistic effect of the limiting components and fixing components ensures that the BMS component remains stable during operation, preventing loosening or positional displacement during equipment operation, thus enhancing the stability and safety of the equipment. Second, the simplified design using a single fixing screw in conjunction with the limiting component makes the installation and disassembly process more convenient and faster, while reducing the difficulty and time cost of manual operation and improving work efficiency. Finally, the design allows for quick disassembly of the BMS component by easily adjusting the unlocking state of the limiting component, facilitating component repair and replacement, reducing maintenance time and costs, thereby optimizing equipment maintainability, extending equipment lifespan, and improving overall performance and reliability.

[0036] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0037] Reference Figure 1 This application discloses a BMS component installation structure for an energy storage device, comprising:

[0038] The housing 1 is provided with an installation cavity 11 and an openable cover plate 12. In this embodiment, the installation cavity 11 is opened on the side of the housing 1, and the cover plate 12 is correspondingly provided with the installation cavity 11 and can seal the installation cavity 11.

[0039] BMS component 2 includes a protective housing 3 and BMS components 21 that are detachably installed in the protective housing 3. In this embodiment, BMS components 21 include, but are not limited to, an integrated BMS board, which is equipped with status indicator lights. The protective housing 3 can provide protection for BMS components 21, avoid interference and damage to BMS components 21 from the external environment, and ensure the safe operation of BMS components 21.

[0040] Fastener 4 detachably fixes the protective housing 3 into the mounting cavity 11;

[0041] The limiting component 5 has a limiting state and an unlocking state; when it is in the limiting state, the limiting component 5 and the fixing component 4 work together to limit and fix the protective housing 3 in the mounting cavity 11, ensuring the stability of the BMS component 2 during operation.

[0042] When in the unlocked state, the operator can release the fixing effect of the limiting member 5 and the fixing member 4, so that the protective housing 3 can move relative to the mounting cavity 11 and be released from the limit, making it convenient to disassemble or replace the BMS component 2.

[0043] In this embodiment, the cover plate 12 is detachably fixed to the side of the housing 1 by mounting screws 6, which pass through the cover plate 12 and are threadedly connected to the housing 1. The installation cavity 11 can be opened and closed by installing and removing the cover plate 12. The cover plate 12 facilitates the operator to perform regular maintenance, inspection or replacement of the BMS component 2 in the installation cavity 11. Furthermore, during the operation of the energy storage device, the cover plate 12 has good protective performance, which can prevent external factors from damaging the BMS component 2 in the installation cavity 11, thereby improving the reliability of the equipment and extending its service life.

[0044] During the assembly of the energy storage equipment, the BMS components 21 are first installed inside the protective housing 3. The protective housing 3 is then installed into the mounting cavity 11 of the housing 1. The protective housing 3 is fixed in the mounting cavity 11 by the limiting component 5 and the fixing component 4 to ensure that the BMS component 2 is stable and does not move. Then, the cover plate 12 is installed and the cover plate 12 is threadedly connected and fixed to the housing 1 using the mounting screws 6. The cover plate 12 seals the mounting cavity 11, providing a stable and reliable installation environment for the BMS component 2.

[0045] If BMS component 2 needs to be replaced or maintained, first remove the mounting screws 6 and cover plate 12, so that the mounting cavity 11 is in the open state. Then remove the fastener 4 inside the mounting cavity 11 to release the fastener 4 from the protective housing 3. Then adjust the limiting member 5 to put it into the unlocked state. In the unlocked state, the protective housing 3 can move relative to the mounting cavity 11 and easily disengage from the limiting position. At this time, BMS component 2 can be quickly disassembled. After disassembly, the protective housing 3 can be opened to take out the BMS component 21 that needs to be replaced or maintained. This design can replace or repair only the faulty BMS component 2 without replacing the entire energy storage device. This design achieves the purpose of replacing BMS component 2 separately, improving maintenance efficiency and reducing costs.

[0046] Reference Figure 1-3 In this embodiment, the protective housing 3 includes a base 32 and an upper housing 31. The BMS component 21 is installed in the receiving space formed by the upper housing 31 and the base 32. This receiving space can provide sufficient protection to ensure that the BMS component 21 is not affected or damaged by the external environment. In this embodiment, the base 32 and the upper housing 31 are connected and fixed by four connecting screws 33. The connecting screws 33 pass through the holes on the base 32 and are inserted into the holes on the upper housing 31 to be threaded and fixed. When disassembly is required, the four connecting screws 33 are loosened and removed to release the fixation of the base 32 and the upper housing 31, so that the base 32 and the upper housing 31 can be easily separated. That is, the protective housing 3 can be quickly disassembled to access the BMS component 21 in the receiving space, thereby facilitating the inspection, maintenance and replacement of the BMS component 21.

[0047] To further improve the ease of loading and unloading BMS component 2, an operating handle 34 is provided on the upper shell 31 of the protective housing 3. Operators can easily lift, move, or adjust the position of the protective housing 3 using the operating handle 34. This design not only improves the ease of operation of BMS component 2, but also reduces misoperation during installation and disassembly, and improves overall work efficiency.

[0048] To facilitate observation of the health status of BMS components 21, an observation hole 35 is provided on the upper shell 31 of the protective housing 3. The observation hole 35 allows users to directly observe the status indicator lights on the BMS components 21 without disassembling the protective housing 3, thereby conveniently and quickly checking the working status of the BMS components 21, such as battery charging and discharging status, fault indications, etc., thus saving maintenance time and improving operating efficiency. In addition, the design of the observation hole 35 enhances the safety and convenience of the equipment. Users do not need to frequently open the protective housing 3 to judge the health status of the BMS system, thereby avoiding potential risks or damage caused by disassembly and improving the safety of the working environment.

[0049] Reference Figure 3-5 In this embodiment, a fixing plate 13 is provided in the mounting cavity 11. The fixing plate 13 is vertically arranged and is used to fix the protective shell 3 in the mounting cavity 11. The limiting member 5 includes a limiting hole 51 on the protective shell 3 and a snap-fit ​​screw 52 on the fixing plate 13. In this embodiment, the limiting hole 51 is provided on the base 32 of the protective shell 3. Two limiting holes 51 are provided on the outer wall of the base 32. Two snap-fit ​​screws 52 are provided on the fixing plate 13 in the mounting cavity 11. The snap-fit ​​screws 52 are provided one-to-one with the limiting holes 51. The limiting holes 51 are respectively hung on the corresponding snap-fit ​​screws 52. The cooperation between the limiting holes 51 and the snap-fit ​​screws 52 realizes the stable installation of the protective shell 3. The limiting hole 51 includes a connecting limiting section 511 and an operating section 512. The limiting hole 51 is fixed by abutting the snap-fit ​​screw 52 through the limiting section 511. The limiting hole 51 can enter or disengage from the snap-fit ​​screw 52 through the operating section 512.

[0050] In practical use, the installation process is simple and easy due to the hanging method of the limiting hole 51 and the snap-fit ​​screw 52. After the limiting hole 51 enters the snap-fit ​​screw 52 through the operating section 512, the protective shell 3 is fixed to the limiting section 511 by moving downward. The operation is intuitive and quick. Furthermore, the abutment and fixation between the limiting section 511 and the snap-fit ​​screw 52 can ensure the stability of the protective shell 3 after installation. When disassembling, the protective shell 3 moves upward so that the operating section 512 of the limiting hole 51 disengages from the snap-fit ​​screw 52, ​​simplifying the disassembly process and reducing disassembly time. Moreover, the limiting hole 51 will only disengage from the snap-fit ​​screw 52 when the protective shell 3 moves upward, thereby avoiding accidental disassembly or loosening and improving the safety of installation and removal.

[0051] In this embodiment, the housing 1 has a step 7 protruding into the mounting cavity 11. Therefore, when disassembling and removing the BMS component 2, the BMS component 2 needs to be tilted at a certain angle to avoid the step 7 position, and then the BMS component 2 is moved to the outside of the housing 1, the wiring harness is disconnected, and the disassembly is completed.

[0052] To facilitate the mounting of the limiting hole 51 onto the snap-fit ​​screw 52, ​​the diameter of the operating section 512 of the limiting hole 51 is designed to be larger than the head diameter of the snap-fit ​​screw 52. This allows the limiting hole 51 to smoothly enter or disengage from the snap-fit ​​screw 52 during installation and disassembly, achieving a quick installation and disassembly effect. It also prevents excessive wear or damage between the protective housing 3 and the snap-fit ​​screw 52, ​​thereby extending the service life.

[0053] To prevent accidental disassembly or loosening, the diameter of the limiting section 511 of the limiting hole 51 is smaller than the head diameter of the snap-fit ​​screw 52, ​​and the diameter of the limiting section 511 is greater than or equal to the screw diameter of the snap-fit ​​screw 52. In this embodiment, the diameter of the limiting section 511 is equal to the screw diameter of the snap-fit ​​screw 52, ​​so that the limiting section 511 can be tightly fitted with the screw portion of the snap-fit ​​screw 52. Therefore, after installation, the protective housing 3 can be stably fixed in position without loosening or slipping. Even under vibration or external force, the protective housing 3 can remain stable, thereby increasing the safety and reliability of the system.

[0054] In this embodiment, the fixing member 4 includes a fixing screw 41. The fixing screw 41 is a single screw. The fixing screw 41 passes through the protective housing 3 and is inserted into the fixing plate 13 and threadedly connected to the fixing plate 13. In this embodiment, the fixing screw 41 passes through the upper housing 31, BMS component 21, base 32, and fixing plate 13 in sequence, and is threadedly connected and fixed to the fixing plate 13. The fixing screw 41 and the limiting member 5 work together to fix the protective housing 3 on the fixing plate 13, thereby completing the installation of the BMS component 2.

[0055] In this process, by adopting a single fixing screw 41 design, the number of screws is reduced, and the installation and disassembly steps are simplified. When disassembling, only one screw needs to be loosened to easily remove the protective housing 3. The entire installation process is faster and more convenient, thereby reducing the complexity of operation and time costs. Furthermore, due to the synergistic fixing effect of the single screw and the limiting member 5, the installation stability of the protective housing 3 can be ensured while reducing the number of operation steps, thereby ensuring the reliable installation of the BMS component 2 and preventing the BMS component 2 from affecting normal operation due to loosening or instability during operation.

[0056] The implementation principle of this application embodiment is as follows: When assembling the energy storage device, firstly, the BMS component 21 is installed in the accommodating space formed by the upper shell 31 and the base 32, and then four connecting screws 33 are used to sequentially thread and fix the base 32 to the upper shell 31 to form a complete protective shell 3, which forms a cavity protection for the BMS component 21, and completes the assembly of the BMS component 2.

[0057] Next, the protective housing 3 is installed into the mounting cavity 11 of the housing 1, and the protective housing 3 is fixed to the fixing plate 13 by the limiting member 5 and the fixing member 4. Specifically, the operator uses the operating handle 34 to align the limiting hole 51 of the protective housing 3 with the snap-fit ​​screw 52 on the fixing plate 13. At this time, the operating section 512 of the limiting hole 51 contacts the snap-fit ​​screw 52, ​​allowing it to easily enter the snap-fit ​​screw 52. After the limiting hole 51 and the snap-fit ​​screw 52 are properly engaged, the operator releases the operating handle 34, and the protective housing 3 will move down, allowing the limiting hole 51 to be properly engaged with the fixing plate 13. The limiting section 511 of the positioning hole 51 abuts and is fixed with the snap-fit ​​screw 52 to ensure that the protective housing 3 is stably hung on the fixing plate 13. Next, the fixing screw 41 is inserted into the fixing plate 13 in the mounting cavity 11 through the hole on the protective housing 3. The fixing screw 41 is threaded to the fixing plate 13 to firmly fix the protective housing 3 to the fixing plate 13. Then, the cover plate 12 is installed. The cover plate 12 is threaded to the housing 1 using the mounting screw 6. The cover plate 12 seals the mounting cavity 11 to provide a stable and reliable installation environment for the BMS component 2.

[0058] If BMS component 2 needs to be replaced or maintained, first remove the mounting screws 6 and cover plate 12, so that the mounting cavity 11 is in the open state. Then remove the fixing screws 41 in the mounting cavity 11. By loosening the fixing screws 41 and removing them, the fixing effect of the fixing screws 41 on the protective housing 3 is released. Then adjust the limiting member 5 to put it into the unlocked state. Specifically, the operator moves the protective housing 3 upward. At this time, the operating section 512 of the limiting hole 51 contacts the snap-fit ​​screw 52, ​​so that it can be easily disengaged from the snap-fit ​​screw 52. When the limiting hole 51 is completely disengaged from the snap-fit ​​screw 52, ​​the protective housing 3 can move freely. At this time, the BMS component 2 needs to be tilted at a certain angle to avoid the step 7 position. Then move the BMS component 2 to the outside of the housing 1, disconnect the wiring harness, and complete the disassembly. Then replace it with a new BMS component 2 and install the new BMS component 2 using the same installation steps as before.

[0059] The installation structure of the BMS component 2 in this energy storage device achieves stable installation and convenient disassembly of the BMS component 2 through the synergistic action of the protective housing 3, the limiting component 5, and the fixing component 4, thereby simplifying the process of installing, maintaining, and replacing BMS components 21. Operators can easily disassemble the BMS component 2 for maintenance or replacement by simply adjusting the limiting component 5 to the unlocked state, without having to replace the entire energy storage device, thus reducing maintenance and replacement costs. At the same time, the protective housing 3 can be firmly fixed in the mounting cavity 11 with the cooperation of the limiting component 5 and the fixing component 4, ensuring the stability and safety of the equipment during operation, avoiding equipment failure due to loosening or displacement, and improving system reliability. In addition, this design not only improves the maintainability of the equipment and shortens the maintenance time, but also improves system reliability and extends the service life of the equipment, optimizing the overall performance of the energy storage device.

[0060] The BMS component 2 installation structure of this application provides an efficient, convenient, and stable method for installing and disassembling the BMS component 2 through the synergistic action of the protective housing 3, the limiting component 5, and the fixing component 4, ensuring the stability and safety of the BMS component 2 during equipment operation. Among them, the protective housing 3 achieves a stable installation of the BMS component 2 through the cooperation of the limiting hole 51 and the snap-fit ​​screw 52, ​​avoiding loosening or positional displacement caused by vibration or external force, thereby improving the reliability of the equipment and extending its service life.

[0061] In addition, the ingenious design of the limiting component 5 and the fixing component 4 enables the BMS component 2 to be maintained or the BMS components 21 to be replaced quickly and easily without replacing the entire component. This structure not only simplifies the installation and disassembly process and improves the ease of operation, but also significantly reduces the cost of maintenance and replacement, reduces equipment downtime, and thus optimizes the overall performance of the energy storage equipment.

[0062] Meanwhile, in this solution, the design of a single fixing screw 41 further enhances the convenience and efficiency of installation and disassembly. By reducing the number of screws and simplifying the operation steps, operators only need to loosen one screw to easily disassemble the protective housing 3, reducing the time and effort required during installation and disassembly. This enables a rapid response to maintenance needs when required, improving the maintainability and service life of the equipment.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
