Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and in particular to a BMS integrated module and a battery pack. Background Art

[0002] With China's increasing emphasis on green travel, the electric vehicle industry is booming, and user demand for longer driving range is also increasing. To meet this demand, many electric vehicle manufacturers have turned their attention to high-capacity power battery systems. Given the same battery envelope space and cell selection, increasing the total capacity of a battery pack requires more battery modules, which gradually reduces the space available for other components within the battery pack. Therefore, optimizing component structure to reduce installation space and fully utilize seemingly unnecessary, irregularly shaped small envelopes has become a question that designers need to carefully consider.

[0003] As we all know, the BMS (Battery Management System) is a core component in power battery systems. However, with the continuous upgrading of products, the design envelope of power battery systems has become increasingly compact, but the BMS installation and fixturing scheme has remained basically unchanged. Typically, each BMS main board or BMS slave board in the BMS is equipped with a separate mounting bracket. The BMS main board and BMS slave boards are then placed horizontally in a flat pattern inside the battery pack. This undoubtedly increases the internal space occupied by the battery pack and reduces space utilization.

[0004] Therefore, there is a need to improve the existing technology.

[0005] The above information is presented as background information only to assist with an understanding of the present disclosure and is not a determination or admission that any of the above may be applicable as prior art with respect to the present disclosure. Utility Model Content

[0048] Example 1

[0049] Please refer to Figure 1-4The embodiment of the present invention provides a BMS integrated module that can provide a solution with stable and reliable performance and compact space for the battery management system (BMS) of electric vehicles. The BMS integrated module specifically includes a BMS main board 301, a BMS slave board 302 and a fixing component 303; wherein,

[0050] The BMS main board 301 and the BMS slave board 302 are spaced apart on opposite sides of the fixed component 303 along the Y direction. Multiple connectors 310 are installed on one side of the BMS main board 301 and the BMS slave board 302 along the Z direction. The BMS integrated module is electrically connected to the battery module through a wiring harness 311 inserted into the connector 310.

[0051] It should be noted that, first, the BMS main board 301 and the BMS slave board 302 are both placed vertically along the Z direction. This layout fully utilizes the vertical space within the battery pack, effectively avoiding the space waste of traditional flat layouts. In this way, the internal space of the battery pack is maximized, allowing it to accommodate more battery modules, thereby increasing the battery pack's energy storage capacity and extending the electric vehicle's range.

[0052] Secondly, the BMS main board 301 and the BMS slave board 302 are cleverly positioned along the Y-axis on opposite sides of the fixing assembly 303. This design not only simplifies the module installation process but also allows the BMS main board 301 and the BMS slave board 302 to share the fixing assembly 303. This means that within the limited space of the battery pack, the number of components required to support and secure the BMS main board 301 and the BMS slave board 302 can be reduced, further reducing the space occupied by the BMS integrated module within the battery pack. This not only further improves the internal space utilization of the battery pack but also reduces production costs, making the BMS integrated module more competitive in the market.

[0053] Furthermore, the BMS main board 301 and the BMS slave board 302 are key control and data processing units, and they are carefully arranged with multiple connectors 310 on one side along the Z direction. These connectors 310 are not only bridges for physical connection, but also portals for electrical signal and data exchange.

[0054] Each connector 310 is designed with a precise docking port and a secure locking mechanism to ensure a tight and reliable connection with the wiring harness 311. The wiring harness 311 acts as an electrical connection medium. One end of the wiring harness 311 plugs into the connector 310, establishing electrical communication with the circuits on the BMS motherboard 301 and BMS slave board 302. The other end extends to the battery module, connecting to the module's internal electrical system.

[0055] This design enables efficient electrical connection between the BMS integrated module and the battery module, enabling real-time battery status monitoring, power management, balancing control, and safety protection. The multiple connector configuration also enhances system flexibility and scalability, facilitating modular upgrades and maintenance based on actual needs.

[0056] This design also helps improve the battery pack's heat dissipation performance. Since both the BMS mainboard 301 and the BMS slave board 302 are positioned vertically, the module's heat dissipation area is increased, which helps improve heat dissipation efficiency. Furthermore, the design of the fixing assembly 303 fully considers heat dissipation requirements, further enhancing the module's heat dissipation performance through the rational design of the ventilation channels. This optimized heat dissipation design helps ensure stable performance and reliability of the battery pack under various operating conditions.

[0057] Please refer again Figure 1-4 In this embodiment, the fixing assembly 303 includes at least two fixing brackets 3031 arranged relatively spaced apart along the X direction;

[0058] At least two fixing brackets 3031 are symmetrically arranged.

[0059] It should be noted that there should be at least two fixing brackets 3031 to ensure the stability and reliability of the BMS main board 301 and the BMS slave board 302. Taking two fixing brackets 3031 as an example, this design can provide more solid support, making the BMS integrated module more stable inside the battery pack, thereby preventing damage or performance degradation caused by vibration or external impact.

[0060] The two fixing brackets 3031 are symmetrically spaced between the BMS main board 301 and the BMS slave board 302. This feature eliminates the need for additional space within the battery pack due to the increased number of fixing brackets 3031 and simplifies module installation. The symmetrical design allows for more precise positioning of the module within the battery pack, avoiding various issues caused by improper installation. Furthermore, the symmetrical placement of the fixing brackets 3031 ensures the module's balance within the battery pack, preventing safety hazards caused by a shifted center of gravity.

[0061] In this embodiment, the BMS main board 301 and the BMS slave board 302 are detachably connected to the fixing bracket 3031 .

[0062] It should be noted that the BMS main board 301 and the BMS slave board 302 are detachably connected to the fixing bracket 3031. This design makes the installation and removal of the module more convenient, and also facilitates the maintenance and upgrade of the module.

[0063] The BMS main board 301 and BMS slave board 302 can be quickly connected and disconnected from the fixing bracket 3031 through the detachable connection. During module installation, the BMS main board 301 and BMS slave board 302 only need to be connected to the corresponding fixing bracket 3031. This connection method is simple and convenient, requiring no special tools, and greatly improving production efficiency.

[0064] Similarly, during module disassembly and maintenance, the BMS mainboard 301 and BMS slave board 302 simply need to be disconnected from the fixing bracket 3031. This design avoids the tedious process of disassembling the entire module, making maintenance and upgrades more efficient. Furthermore, since the BMS mainboard 301 and BMS slave board 302 are detachably connected to the fixing bracket 3031, module maintenance and upgrades do not require disassembly of the entire battery pack, reducing maintenance and upgrade costs and time.

[0065] Regarding the specific embodiment in which the BMS main board 301 and the BMS slave board 302 are detachably connected to the fixing bracket 3031 , for example, the fixing bracket 3031 may be provided with a connecting hole 304 ;

[0066] Then, the BMS main board 301 and the BMS slave board 302 are fixedly connected to the fixing bracket 3031 by respectively passing the bolts 305 through the corresponding connection holes 304 .

[0067] Specifically, after one end of the bolt 305 passes through the connection hole 304 , it can be fixed to the other end of the bolt 305 by a fastener such as a nut, thereby achieving a fixed connection between the BMS main board 301 and the BMS slave board 302 and the fixing bracket 3031 .

[0068] This connection method has high stability and reliability, and can ensure the stable operation of the BMS main board 301 and the BMS slave board 302 inside the battery pack.

[0069] Please refer again Figure 2-3 The design of this embodiment fully demonstrates the high attention to detail and practicality. In particular, the wiring harness fixing hole 306 is carefully opened on the fixing bracket 3031. This innovative design significantly improves the overall performance and operational convenience of the BMS integrated module.

[0070] The design of the harness fixing hole 306 not only optimizes wiring harness management within the module but also enhances its stability and safety. A harness fixing member 309 is located within the harness fixing hole 306 to securely fasten the harness 311. This effectively prevents loosening, wear, or short circuits that may occur during vibration or movement of the harness 311, thereby ensuring stable operation of the battery management system.

[0071] Furthermore, the use of wire harness fixture 309 simplifies the installation and maintenance of wire harness 311. Users can simply secure wire harness 311 to wire harness fixture 309 without the need for complex tools or equipment, significantly improving work efficiency. Furthermore, when maintenance or replacement of wire harness 311 is required, users can simply remove wire harness 311 from wire harness fixture 309 and proceed with subsequent operations.

[0072] In summary, the design of the harness fixing hole 306 on the fixing bracket 3031 and the harness fixing member 309 therein in this embodiment not only improves the stability and safety of the BMS integrated module, but also makes the module's harness management more convenient and efficient. This innovative design fully demonstrates this embodiment's attention to detail in the electric vehicle battery management system and its in-depth understanding of user needs.

[0073] Please refer again Figure 4 The BMS integrated module in this embodiment is well-designed and practical. In particular, the fixing bracket 3031 is provided with mounting holes 307 for fixing it to the battery pack, providing an important guarantee for the stable installation of the entire module.

[0074] These mounting holes 307 are not only rationally designed but also precisely positioned, ensuring that the fixing bracket 3031 can be accurately installed in the predetermined position within the battery pack. Through these mounting holes 307, appropriate fasteners (such as bolts and nuts) can be used to tightly connect the fixing bracket 3031 to the structural components within the battery pack, thereby ensuring that the BMS main board 301 and BMS slave board 302 are stably fixed within the battery pack.

[0075] This design not only enhances the stability and reliability of the BMS integrated module, but also makes the installation process easier and more efficient. Installers can easily locate the module according to the location of the mounting holes 307 and tighten it using standard installation tools without the need for additional processing or adjustment.

[0076] Furthermore, the design of the mounting holes 307 also takes into account the module's maintainability and upgradeability. When module maintenance or upgrades are required, the mounting bracket 3031 can be easily removed from the battery pack by removing the fasteners, and then the necessary operations can be performed. This design makes module maintenance and upgrades more flexible and convenient.

[0077] Please refer again Figure 3-4 This embodiment shows in detail the complex but practical design of the fixing bracket 3031. Specifically, the fixing bracket 3031 consists of several key parts, including two fixing base plates 30311, a connecting plate 30312 and a harness fixing plate 30313;

[0078] Two fixed substrates 30311 are spaced apart along the Y direction; connection holes 304 are provided on the fixed substrates 30311; one of the fixed substrates 30311 is detachably connected to the BMS main board 301 via the connection hole 304 provided thereon, and the other fixed substrate 30311 is detachably connected to the BMS slave board 302 via the connection hole 304 provided thereon;

[0079] The bottom of the fixed substrate 30311 has a bent portion 30314 connected at an angle along the Y direction.

[0080] The mounting hole 307 is provided on the bent portion 30314;

[0081] The wire harness fixing plate 30313 is provided with a notch 30315 along the X direction. The wire harness fixing plate 30313 is connected to the top of the two notches 30315 along the Y direction to form a cavity for accommodating the wire harness 311 between the two opposing fixing brackets 3031. The wire harness fixing hole 306 is provided in the wire harness fixing plate 30313.

[0082] The connecting plate 30312 is connected to the outer sides of the two fixed base plates 30311 along the Z direction; a flange 308 is provided on the top side of the connecting plate 30312 along the Z direction.

[0083] It's important to note that the coordinated operation of the fixed baseplate 30311, connecting plate 30312, and wiring harness fixing plate 30313 ensures stable installation of the BMS mainboard 301 and BMS slave board 302, and effective wiring harness management. First, the two fixed baseplates 30311 are positioned opposite each other, each detachably connected to the BMS mainboard 301 and BMS slave board 302 via their respective connection holes 304. This design ensures that the BMS mainboard 301 and BMS slave board 302 are securely fixed to the bracket, while also facilitating subsequent maintenance and replacement.

[0084] Secondly, the bottoms of the two fixed base plates 30311 are bent to form a bent portion 30314, and both have mounting holes 307. These mounting holes 307 are used to fix the fixing bracket 3031 at a predetermined position inside the battery pack to ensure the stability and reliability of the entire BMS integrated module. At the same time, the design of the bent portion 30314 not only enhances the structural strength of the fixing bracket 3031, but also optimizes its installation layout within the battery pack. Specifically, due to the presence of the bent portion 30314, the fixing bracket 3031 can fit more closely to the internal structure of the battery pack, reducing space occupancy and enhancing the connection stability between the bracket and the battery pack.

[0085] Furthermore, the harness fixing plate 30313 is vertically positioned between the tops of the two fixed base plates 30311 and is fixedly connected to each. Harness fixing holes 306 are provided on the harness fixing plate 30313 for use with harness fixing members 309 to secure the harness 311. This design not only optimizes the layout of the harness 311 but also prevents clutter and interference within the harness 311, thereby improving the safety and reliability of the system.

[0086] Finally, the connecting plate 30312 is vertically positioned between the two fixed base plates 30311 and fixedly connected to each. A flange 308 is provided on the top of the connecting plate 30312, creating a smooth contact area. This design cleverly prevents the wiring harness 311 from coming into contact with sharp edges during routing, significantly reducing the risk of damage to the wiring harness 311 and thereby improving the reliability and durability of the entire system.

[0087] In addition, the flange 308 also has the function of removing burrs. During the production process, burrs may appear on the edge of the connecting plate 30312, which may damage the wiring harness 311. The design of the flange 308 effectively removes these burrs, thereby further protecting the wiring harness 311 from damage.

[0088] Although this application frequently uses terms such as BMS mainboard, BMS slave board, fixing bracket, and connection hole, the use of other terms is not excluded. These terms are used solely to more conveniently describe and explain the essence of this utility model; interpreting them as any additional limitations is contrary to the spirit of this utility model.

[0089] The utility model provides a BMS integrated module, including a BMS main board, a BMS slave board and a fixing bracket. By arranging the BMS main board and the BMS slave board on opposite sides of a fixing component, the BMS main board and the BMS slave board can share the fixing component, thereby reducing the number of fixing components used, thereby reducing the space occupied by the BMS integrated module inside the battery pack. By placing the BMS main board and the BMS slave board vertically, the vertical space inside the battery pack can be fully utilized, avoiding the waste of space due to a flat layout, thereby further improving the internal space utilization of the battery pack.

[0091] Please refer to Figure 5-7 , an embodiment of the present utility model provides a battery pack, comprising a box body 1, a battery module 2 installed in the box body 1, and a BMS integrated module 3 as provided in the above-mentioned embodiment 1;

[0092] The battery module 2 and the BMS integrated module 3 are electrically connected via the wiring harness 311 .

[0093] It can be understood that, since the battery pack provided in this embodiment has the BMS integrated module 3 provided in the above-mentioned embodiment 1, it also has the same beneficial effects, which will not be described in detail here.

[0094] Please refer again Figure 6-7 In this embodiment, a BMS mounting bracket 4 is provided on the inner bottom surface of the box 1;

[0095] The BMS integrated module 3 is detachably mounted on the BMS mounting bracket 4 .

[0096] It should be noted that the inner bottom surface of the housing 1 is provided with a BMS mounting bracket 4 for supporting and securing the BMS integrated module 3. The BMS integrated module 3 is detachably mounted on the BMS mounting bracket 4, making installation, removal, maintenance, and upgrades of the module more convenient. The BMS mounting bracket 4 ensures that the BMS integrated module 3 is stably mounted within the housing 1, improving the stability and reliability of the entire battery pack.
