Description

Technical Field

[0001] This utility model belongs to the field of battery technology, specifically relating to a battery module that combines a pressure sensor and a BMS. Background Technology

[0002] Currently, the safety and reliability of battery modules remain the primary consideration in the design of energy storage systems. To ensure their safe operation, a multi-parameter-based condition monitoring system is considered a key risk management tool.

[0003] The mainstream industry solution focuses on real-time acquisition of battery voltage and temperature parameters, and completes data parsing and safety threshold assessment through the battery management system (BMS board), thereby achieving dynamic monitoring of the module's operating status. This functional module is mainly integrated by the integrated busbar (Cell contact system).

[0004] Typically, when performing pressure testing on individual battery cells, the existing approach involves placing the pressure sensing element on a circuit board and electrically connecting it to the wiring. This means that each individual battery cell requires a separate wiring connection to the pressure sensing element on the circuit board, which is not conducive to cell-side production. Furthermore, the existing approach involves configuring a BMS board within a battery pack. The BMS board is installed in a separate area within the battery pack and electrically connected to the integrated busbar via wiring harnesses. This approach not only hinders the optimization of the internal structure of the battery pack but also results in a longer response time for the BMS board, reducing the overall system efficiency.

[0016] The first connector and a plurality of second connectors are all disposed on the FPC assembly. The second connectors are used to connect with the pressure sensor. Utilizing the flexibility of the FPC assembly, the FPC assembly can be directly bent to facilitate the connection of the first connector with the BMS board.

[0017] In some implementations, the FPC component includes a first connection portion and a second connection portion;

[0018] The first connecting portion is disposed on the blister box, one end of the second connecting portion is connected to the first connecting portion, and the other end of the second connecting portion is bent toward the BMS board;

[0019] The first connector is located on the second connection part at one end near the BMS board, and the second connector is located on the first connection part, corresponding to the position of the pressure sensor, so as to realize the plug-in connection between the first connector and the second connector.

[0020] In some implementations, the integrated busbar also includes multiple nickel plates for collecting the voltage of the individual battery cells;

[0021] The nickel strip is connected to the FPC assembly, and the voltage data of the individual battery cells is detected through the nickel strip to ensure the health status of the battery module.

[0048] Example 1:

[0049] As is known, a battery pack is an energy unit formed by further integrating multiple battery modules and combining them with components such as a BMS board and a housing structure. In a battery pack, a separate area is usually reserved for the installation of the BMS board, which is electrically connected to the integrated busbar through a wiring harness. This allows for the monitoring of the health status of multiple battery modules. In other words, in existing solutions, a single battery module is not equipped with a separate BMS board.

[0050] Please see Figures 1-3 This embodiment provides a battery module that combines pressure sensors and a BMS, including a cell module 100, an integrated busbar 200, multiple pressure sensors 400, and a separate BMS board 300 to monitor the health status of the battery module.

[0051] The battery module 100 includes a first end plate 110, a second end plate 120, and a plurality of individual battery cells 130, which are sequentially connected and clamped between the first end plate 110 and the second end plate 120.

[0052] Specifically, multiple battery cells 130 are arranged in sequence and closely attached to each other. The first and last battery cells 130 are respectively connected to a first end plate 110 and a second end plate 120. The first end plate 110 and the second end plate 120 are used to clamp and limit the multiple battery cells 130. At the same time, the first end plate 110 and the second end plate 120 can also be used to lock and connect with other structural components during subsequent assembly.

[0053] In this example, there are a total of 12 battery cells 130. The 12 battery cells 130 are arranged in sequence and clamped between the first end plate 110 and the second end plate 120. Of course, the number of battery cells 130 can be adjusted according to actual needs, and there is no limitation on this in this example.

[0054] Each battery cell 130 has a pole post 131 on its upper end surface. Each pressure sensor 400 is disposed on the upper end surface of each battery cell 130. An integrated busbar 200 covers the upper end surfaces of multiple battery cells 130. The pressure sensor 400 and the pole post 131 are both connected to the integrated busbar 200.

[0055] The pressure sensor 400 is used to monitor the internal pressure of the battery cell 130. It can issue an early warning when the battery cell 130 shows signs of thermal runaway. This pressure change-based monitoring method can provide warnings earlier than other variables such as temperature. In this example, each pressure sensor 400 is installed on each battery cell 130 to detect and manage each battery cell 130. It can quickly locate the problematic battery cell 130 and provide accurate assessment.

[0056] Typically, the terminal post 131 on the battery cell 130 needs to be connected to the integrated busbar 200 in order to enable some monitoring functions of the battery cell 130. Therefore, placing the pressure sensor 400 on the upper surface of the battery cell 130 with the terminal post 131 facilitates the connection between the pressure sensor 400 and the integrated busbar 200.

[0057] The BMS board 300 is located on the outside of the first end plate 110 or the second end plate 120, and the integrated busbar is provided with a first connector 500 for plugging and connecting with the BMS board 300.

[0058] In the traditional approach, each battery pack contains a BMS board 300 with a dedicated area for its installation. The BMS board 300 is then connected to the integrated busbar via a wiring harness. This requires reserving space within the battery pack for the BMS board 300 and wiring. However, in this embodiment, the BMS board 300 is directly mounted on the outside of the first end plate 110 or the second end plate 120, establishing a direct connection with it. This eliminates the need for separate installation within the battery pack. Furthermore, since the BMS board 300 is mounted on the first end plate 110 or the second end plate 120, the distance between it and the integrated busbar 200 is minimal. Therefore, compared to the traditional approach, this reduces the amount of wiring required.

[0059] In some implementations, the BMS board 300 is provided with a first connector 310, and the first connector 500 is directly plugged into the first connector 310, so that the BMS board 300 and the integrated busbar 200 can be connected without the need for wiring harnesses, thereby reducing the wiring harness layout and optimizing the structure of the battery module.

[0060] The first connector 310 on the BMS board 300 and the first connector 500 on the integrated busbar 200 are set to a relative relationship. When connecting, the first connector 500 can be directly plugged into the first connector 310, thus establishing the connection between the integrated busbar 200 and the BMS board 300.

[0061] In some embodiments, the first end plate 110 is provided with a first positioning hole 111 for positioning and connecting with the BMS board 300, and the BMS board 300 is provided with a second positioning hole 320 that matches the first positioning hole 111; screws are inserted into the first positioning hole 111 and the second positioning hole 320 to ensure the connection stability and positioning accuracy between the BMS board 300 and the first end plate 110.

[0062] In this example, the BMS board 300 is positioned and connected to the first end plate 110. For instance, two or four symmetrically arranged first positioning holes 111 are provided on the first end plate 110. Correspondingly, second positioning holes 320 matching the number and position of the first positioning holes 111 are provided on the BMS board 300. During assembly, after aligning the second positioning holes 320 on the BMS board 300 with the first positioning holes 111 on the first end plate 110, screws are inserted outside the second positioning holes 320, allowing the screws to pass through the second positioning holes 320 and into the first positioning holes 111, thus achieving a stable connection between the BMS board 300 and the first end plate 110. Of course, the BMS board 300 can also be connected to the second end plate 120; this example does not limit this connection.

[0063] This embodiment provides a battery module that combines a pressure sensor and a BMS. The pressure sensor 400 is directly placed on the upper surface of each battery cell 130. Compared with the traditional method of integrating the pressure detection element on the circuit board and then connecting it to the battery cell 130 by wiring, this utility model can complete the welding of the pressure sensor 400 during the production process of the battery cell 130, without the need for separate wiring of the battery cell 130. The process is simpler. Furthermore, by inspecting and managing each battery cell 130, problematic battery cells 130 can be quickly located, providing accurate assessment.

[0064] A separate BMS board 300 is configured in the battery module to monitor and analyze the voltage, temperature, and internal pressure of the individual battery cells 130, enabling early warning functions. Compared to the traditional method of configuring a BMS board 300 for each battery pack and reserving a separate area for installation, the BMS board 300 of this invention only needs to process the data of the battery module, reducing the computational load of the main control unit, shortening the response time, and improving the overall system efficiency. Furthermore, the BMS board 300 can be placed on the outside of the first end plate 110 or the second end plate 120 and connected to the integrated busbar 200, reducing the wiring harness layout, optimizing the internal structure of the battery pack, and effectively improving the production efficiency of the battery pack.

[0065] Example 2:

[0066] This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-3 Based on the above, refer to Figure 4 and Figure 5 .

[0067] In some embodiments, the integrated busbar 200 includes a blister pack 210, an FPC assembly 220, a plurality of conductive aluminum busbars 230, and a plurality of second connectors 240.

[0068] The FPC assembly 220 is disposed on the blister box 210. For example, the FPC assembly 220 is distributed along the arrangement direction of the multiple battery cells 130, so that the FPC assembly 220 can be distributed above each battery cell 130. Multiple conductive aluminum busbars 230 are distributed on both sides of the FPC assembly 220. Similarly, the multiple conductive aluminum busbars 230 are also distributed along the arrangement direction of the multiple battery cells 130. The conductive aluminum busbars 230 connect the FPC assembly 220 and the terminal post 131 of the battery cell 130.

[0069] Understandably, each battery cell 130 has two terminals 131, including a positive terminal 131 and a negative terminal 131. Both the positive terminal 131 and the negative terminal 131 need to establish a connection with the FPC assembly 220 through the conductive aluminum busbar 230. Therefore, the conductive aluminum busbars 230 distributed on both sides of the FPC assembly 220 correspond to the positive terminals 131 and the negative terminals 131 of multiple battery cells 130 on the same side, respectively.

[0070] The first connector 500 and multiple second connectors 240 are both disposed on the FPC assembly 220. The second connectors 240 are used to connect with the pressure sensor 400. As for the connection of the first connector 500, the flexible nature of the FPC assembly 220 is utilized, and the FPC assembly 220 is directly bent to allow the first connector 500 to connect with the BMS board 300.

[0071] In this embodiment, since the pressure sensor 400 is directly mounted on the upper surface of the battery cell 130, it can be connected to the integrated busbar 200 by inserting a second connector 240 onto the integrated busbar 200. As for the first connector 500, since it is mounted on the FPC assembly 220 and the FPC assembly 220 has flexible characteristics, the length of the FPC assembly 220 can be appropriately increased during the design process, so that it can extend to the BMS board 300 with the first connector 500, allowing the first connector 500 to be inserted into the BMS board 300.

[0072] In some embodiments, the FPC assembly 220 includes a first connecting portion 221 and a second connecting portion 222, which are connected to each other, making the FPC assembly 220 a single integrated structure. The first connecting portion 221 is disposed on the blister pack 210, one end of the second connecting portion 222 is connected to the first connecting portion 221, and the other end of the second connecting portion 222 is bent toward the BMS board 300. A first connector 500 is located on the second connecting portion 222 at the end closer to the BMS board 300, and a second connector 240 is located on the first connecting portion 221, corresponding to the position of the pressure sensor 400, thereby realizing the insertion connection between the first connector 500 and the second connector 240.

[0073] Understandably, the first connection portion 221 is distributed along the arrangement direction of the individual battery cells 130, so that the first connection portion 221 can cover the upper surface of multiple individual battery cells 130, which facilitates the second connector 240 to be inserted and connected to each pressure sensor 400. The second connection portion 222 is bent toward the BMS board 300, so that the first connector 500 located on the second connection portion 222 can be directly inserted into the BMS board 300, reducing the wiring harness layout.

[0074] In some implementations, the integrated busbar 200 also includes multiple nickel plates 250 for collecting the voltage of individual battery cells 130; the nickel plates 250 are connected to the FPC assembly 220, and the voltage data of the individual battery cells 130 are detected through the nickel plates 250 to ensure the health status of the battery module.

[0075] Specifically, the nickel sheet 250 is bonded to the battery cell 130 and the FPC module 220, so that the FPC module 220 can detect the corresponding data of the battery cell 130 through the nickel sheet 250, ensuring the safe and stable operation of the battery module.

[0076] In some embodiments, the blister box 210 is provided with a plurality of first positioning members 211 for positioning and connecting the FPC assembly 220, and the FPC assembly 220 is provided with third positioning holes that match the plurality of first positioning members 211, so as to ensure the assembly stability and positioning accuracy of the FPC assembly 220.

[0077] As is known, the FPC assembly 220 is distributed along the arrangement direction of the individual battery cells 130. Therefore, the FPC assembly 220 has a certain length. Furthermore, the FPC assembly 220 is flexible, necessitating the assurance of its positional stability during assembly. Therefore, in this example, a first positioning element 211 is provided on the blister pack 210, and a corresponding third positioning hole matching the first positioning element 211 is formed on the FPC assembly 220. This ensures the positional stability of the FPC assembly 220, facilitating precise welding with other components.

[0078] Specifically, multiple first positioning elements 211 can be distributed on opposite sides of the FPC assembly 220, with adjacent first positioning elements 211 on the same side spaced apart. For example, there are a total of 12 first positioning elements 211, with 6 first positioning elements 211 distributed on one side of the FPC assembly 220. Of course, this example does not limit the number of first positioning elements 211, and the number of first positioning elements 211 can be adjusted according to actual needs.

[0079] Example 3:

[0080] This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-5 Based on the above, refer to Figure 6 .

[0081] In some embodiments, a heat insulation sheet 600 is provided between two adjacent battery cells 130 to provide effective heat insulation protection between adjacent battery cells 130.

[0082] The integrated busbar 200 is locked to the first end plate 110 and the second end plate 120 to ensure the overall structural stability of the battery module. That is, there is a locking connection between the positions of the integrated busbar 200 corresponding to the first end plate 110 and the second end plate 120 to ensure the assembly stability between the components of the battery module.

[0083] In some embodiments, the first end plate 110, multiple battery cells 130 and the second end plate 120 are fastened together by cable ties 700 to ensure the overall structural stability of the battery module and to facilitate the assembly of the battery module with the housing, etc.

[0084] For example, the cable tie 700 is made of steel and has a certain degree of rigidity to prevent it from breaking due to excessive force. There are two steel cable ties 700, which are locked to the upper and lower ends of the battery module respectively.

[0085] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
