Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention. In the present invention, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0032] In related technologies, data signals collected by the CCS module in a square power battery, such as cell voltage and temperature data, need to be transmitted to the BMS via costly adapter harnesses. Furthermore, the limited internal space of the battery module restricts the arrangement of numerous adapter harnesses. To address these technical problems, a data acquisition integration module and battery pack are proposed below.

[0033] Please see Figures 1 to 5 An embodiment of the present invention provides a data acquisition integration component 100, which includes a wire harness isolation plate 10, a bus 20, a flexible circuit board 30, and a sampling chip 40.

[0034] In this embodiment, the busbar 20 is disposed on the wire harness isolation plate 10. The busbar 20 includes a plurality of bus groups 210 arranged along the length direction of the wire harness isolation plate 10, and each bus group 210 includes a plurality of bus units 211 arranged along the width direction of the wire harness isolation plate 10.

[0035] In this embodiment, the flexible circuit board 30 is disposed on the wire harness isolation plate 10. The flexible circuit board 30 includes a plurality of transmission strips 310 arranged along the width direction of the wire harness isolation plate 10. The transmission strips are disposed between two adjacent busbar units 211.

[0036] In this embodiment, the sampling chip 40 is disposed on the wire harness isolation plate 10 and between two adjacent busbars 210. The sampling chip 40 is electrically connected to the transmission bar and is used to collect the working data of the target battery cell.

[0037] This invention provides a data acquisition integration component 100 and a battery pack. The data acquisition integration component 100 includes a wire harness isolation plate 10 and a busbar 20, a flexible circuit board 30, and a sampling chip 40 disposed on the wire harness isolation plate 10. The busbar 20 includes multiple bus groups 210, and each bus group 210 includes multiple bus units 211. The flexible circuit board 30 includes multiple transmission strips disposed between adjacent multiple bus units 211. The sampling chip 40 is disposed between two adjacent bus groups 210 and is electrically connected to the transmission strips. This application integrates the battery management module's circuit board into the data acquisition integration component 100 by setting the sampling chip 40 electrically connected to the transmission strips between the bus groups 210. This allows the battery cell's working data to be directly transmitted to the sampling chip 40 through the transmission strips, eliminating the need for adapter wire harnesses and solving the technical problem of not being able to arrange a large number of adapter wire harnesses due to space limitations.

[0038] It should be noted that the data acquisition integration component 100 can be integrated into the upper cover of the battery pack. The data acquisition integration component 100 is mainly used to collect the working data of the cells in the battery module, such as temperature data and voltage data, in order to detect the working status of the cells in real time. The sampling chip 40 can directly receive the collected working data.

[0039] It should be noted that the data acquisition integration component 100 may further include a voltage acquisition unit and a temperature acquisition unit disposed on the wire harness isolation plate 10. The voltage acquisition unit and the temperature acquisition unit are electrically connected to the corresponding bus unit 211. The voltage acquisition unit can acquire and transmit the voltage data of the battery cell, and the temperature acquisition unit can acquire and transmit the temperature data of the battery cell.

[0040] It should be noted that the wire harness isolation plate 10 can be formed from a plastic part through injection molding, and the material of the wire harness isolation plate 10 can be PC, PVC, PP, etc.

[0041] It should be noted that the busbar 20, the flexible circuit board 30, and the sampling chip 40 can be disposed on the first side of the wire harness isolation plate 10, and the other side of the wire harness isolation plate 10 can abut against multiple battery cells in the battery module. Simultaneously, the wire harness isolation plate 10 also serves to support the busbar 20 and provide support strength for the entire data acquisition integration assembly 100.

[0042] It should be noted that the arrangement and number of bus units 211 in each bus group 210 are the same, and each bus group 210 may include two rows of bus units 211, with the same number of bus units 211 in each row; for example Figure 1 In the structure, the busbar 20 is provided with 5 bus groups 210, and each bus group 210 may include 4 bus units 211 arranged in a 2x2 pattern. Figure 1 The structure in the data acquisition integration component 100 may only be a part of the data acquisition integration component 100; for example, the complete data acquisition integration component 100 may have multiple components. Figure 1 The specific number of cells depends on the number of battery cells.

[0043] It should be noted that the flexible circuit board 30 may include multiple transmission strips, each transmission strip being electrically connected to two adjacent busbars 211, and each busbar 211 being electrically connected to only one transmission strip; for example... Figure 1 In the structure, Figure 1 The structure is only a part of the complete acquisition integration component 100, therefore Figure 1 Only one transmission bar is shown, which can be electrically connected to four of the bus units 211 in one of the bus groups 210.

[0044] It should be noted that the data acquisition integration component 100 is also provided with an output busbar, which is mounted on the wire harness isolation plate 10 and electrically connected to the busbar 20. In this embodiment, the output busbar can be a copper-aluminum composite busbar, which serves as the output electrode. Its main feature is that the copper busbar and the aluminum busbar are respectively nickel-plated and welded together by polymer diffusion welding or ultrasonic welding. The aluminum busbar can be designed with hot riveting holes for connection to the wire harness isolation plate 10, and the copper busbar can be designed with mounting holes for connection to the output electrode base 50 and the battery module by bolts. The material of the copper busbar can be T2 copper, and the material of the aluminum busbar can be AL1060-O.

[0045] It should be noted that the bus 20 is a series aluminum bus, which can be connected to the battery cell by laser welding and can conduct the current of the battery module. The material of the bus 20 can be AL1060-O.

[0046] The technical solution of this application is described below with reference to specific embodiments.

[0047] Please see Figure 2 and Figure 3The transmission strip includes a first transmission section 311 and a second transmission section 312, which are separately configured. The first transmission section 311 is electrically connected to a first end of the sampling chip 40, and the second transmission section 312 is electrically connected to a second end of the sampling chip 40. The first transmission section 311 is located in the first region 110 of the acquisition integration component 100 and can be electrically connected to a bus unit 211 in the first region 110. The second transmission section 312 is located in the second region 120 of the acquisition integration component 100 and can be electrically connected to a bus unit 211 in the second region 120. The first transmission section 311 can transmit temperature and voltage data acquired in the first region 110 to the sampling chip 40, and the second transmission section 312 can transmit temperature and voltage data acquired in the second region 120 to the sampling chip 40.

[0048] In this embodiment, please refer to Figure 3 Both the first transmission unit 311 and the second transmission unit 312 are provided with gold fingers 313 at their ends. The sampling chip 40 is provided with an electrical connection port corresponding to the gold fingers 313 at the ends corresponding to the first transmission unit 311 and the second transmission unit 312. The first transmission unit 311 and the second transmission unit 312 are electrically connected to the sampling chip 40 through the corresponding gold fingers 313 and the electrical connection port.

[0049] This embodiment sets up sampling chips 40 that are electrically connected to the transmission strip between the bus groups 210, and at the same time, the first transmission unit 311 and the second transmission unit 312, which are set up separately, directly transmit the working data of the cells in different areas to the sampling chips 40. This eliminates the need for adapter bundles, reduces costs, and solves the technical problem of not being able to arrange a large number of adapter bundles due to space limitations.

[0050] Since the wire harness isolation plate 10 is made of plastic, and plastic has poor heat insulation, when the battery cell experiences thermal runaway, heat may be transferred to the sampling chip 40 through the plastic, causing the sampling chip 40 to malfunction.

[0051] Please see Figure 2 , Figure 4 and Figure 5 The acquisition integration component 100 also includes a base 50 disposed on the wire harness isolation plate 10, the base 50 being disposed between the sampling chip 40 and the wire harness isolation plate 10.

[0052] In this embodiment, the base 50 can be made of high-temperature resistant insulating material, and the heat transferred from the battery cell to the wire harness isolation plate 10 can be isolated by the base 50 to prevent the high temperature from being transferred to the sampling chip 40.

[0053] In this embodiment, the acquisition integration component 100 further includes a plurality of positioning posts 60 disposed on the wire harness isolation plate 10, and the plurality of positioning posts 60 are disposed between two adjacent busbars 210; at the same time, the base 50 is provided with a plurality of first positioning holes 611, one first positioning hole 611 corresponding to one positioning post 60, and the plurality of first positioning holes 611 are sleeved on the plurality of positioning posts 60.

[0054] Please see Figure 2 and Figure 4 The wire harness isolation plate 10 can be provided with 5 positioning posts 60. The line connecting the four outer positioning posts 60 forms a rectangle, and the fifth positioning post 60 is located at the center point of the rectangle. At the same time, the base 50 is also provided with 5 first positioning holes 611 corresponding to the 5 positioning posts 60, and the 5 first positioning holes 611 are fitted onto the 5 positioning posts 60 to position the base 50 on the wire harness isolation plate 10.

[0055] Please see Figure 2 and Figure 4 The sampling chip 40 may have multiple second positioning holes 612, each second positioning hole 612 corresponding to a first positioning hole 611, and the center points of the first positioning hole 611 and the second positioning hole 612 are on the same straight line; for example Figure 1 In the structure, the sampling chip 40 may be provided with 5 second positioning holes 612, and the 5 second positioning holes 612 are sleeved on the 5 positioning posts 60 to position the sampling chip 40 on the base 50.

[0056] In related technologies, the battery cell needs a corresponding venting channel to release the gas flow that overflows when the explosion-proof valve of the battery cell is opened, so as to ensure the normal operation of the battery cell. However, when the battery cell experiences thermal runaway, various metal substances that may be carried out by the gas flow when the explosion-proof valve of the battery cell is opened may splash onto the busbar 20, causing a short circuit in the series-connected battery cells.

[0057] Please see Figure 1 and Figure 2 The wire harness isolation plate 10 may have multiple first through holes 621, which are located between multiple busbars 210. These first through holes 621 are used to release the airflow overflowing when the explosion-proof valve of the battery cell is opened. However, since the airflow overflowing from the first through holes 621 may carry metallic substances and sputter onto the sampling chip 40, it can cause the sampling chip 40 to malfunction. Therefore… Figure 1 In the structure, the acquisition integration component 100 also includes a protective component 70 disposed on the sampling chip 40.

[0058] In this embodiment, the protective component 70 may be made of a high-temperature resistant insulating material.

[0059] In this embodiment, the orthographic projection of the sampling chip 40 onto the protective member 70 is located within the protective member 70. That is, the area of ​​the sampling chip 40 can be less than or equal to the area of ​​the protective member 70, so that the protective member 70 completely covers the sampling chip 40, preventing metal substances carried by the airflow from sputtering onto the sampling chip 40. (See also...) Figure 4 and Figure 5 The protective member 70 has a cavity for accommodating the sampling chip 40. The cooperation between the protective member 70 and the base 50 can completely enclose the sampling chip 40.

[0060] In this embodiment, please refer to Figure 2 The protective component 70 is provided with a plurality of third positioning holes 613, the center points of the first positioning hole 611, the second positioning hole 612 and the third positioning hole 613 are on the same straight line, and one third positioning hole 613 corresponds to one second positioning hole 612; for example Figure 1 In the structure, the protective component 70 may be provided with 5 third positioning holes 613, and the 5 third positioning holes 613 are sleeved on the 5 positioning posts 60 to position the alarm component on the sampling chip 40 to protect the sampling chip 40.

[0061] exist Figure 1 and Figure 2 In the structure, double-sided adhesive or other adhesive layers can be used to fix the protective component 70, the sampling chip 40, the base 50 and the wire harness isolation plate 10. This embodiment does not impose any restrictions.

[0062] In this embodiment, please refer to Figure 4 The base 50 may include a base plate 510 and a protrusion 520 disposed on the base plate 510. The protrusion 520 is provided with a second through hole 622. Since the wire harness isolation plate 10 is provided with a first through hole 621 for releasing airflow, in order to provide clearance space for the airflow ejected by the battery cell when the valve is opened, this embodiment can provide a second through hole 622 on the base 50. The first through hole 621 can correspond to the second through hole 622, and the airflow released by the battery cell can be discharged through the first through hole 621 and the second through hole 622.

[0063] In this embodiment, since the sampling chip 40 and the protective component 70 are disposed on the base 50, the sampling chip 40 may be provided with a third through hole 623, and the protective component 70 may be provided with a fourth through hole 624. The centers of the first through hole 621, the second through hole 622, the third through hole 623, and the fourth through hole 624 are located on the same straight line. The flow channel formed by the first through hole 621, the second through hole 622, the third through hole 623, and the fourth through hole 624 is used for the flow of air released by the battery cell when the valve is opened; for example... Figure 1 In the structure, there are two of each of the first through hole 621, the second through hole 622, the third through hole 623 and the fourth through hole 624, and each of the first through hole 621, the second through hole 622, the third through hole 623 and the fourth through hole 624 corresponds to another.

[0064] In this embodiment, since the airflow released from the battery cell carries metallic substances, when the airflow passes through the third through-hole 623, metallic substances may be sputtered onto the side of the third through-hole 623, causing the sampling chip 40 to malfunction. Therefore, this application provides the protrusion 520 structure on the base plate 510, and the second through-hole 622 penetrates the protrusion 520 and the base plate 510, making the protrusion 520 an annular barrel structure. At the same time, the sampling chip 40 is sleeved on the protrusion 520 through the third through-hole 623, and the protective member 70 is sleeved on the protrusion 520 through the fourth through-hole 624.

[0065] In this embodiment, since the protrusion 520 is made of high-temperature resistant insulating material, and the sampling chip 40 and the protective member 70 are both sleeved on the protrusion 520, the protrusion 520 isolates the sampling chip 40 and the protective member 70 from the airflow released from the battery cell, thus preventing the metal material carried by the airflow released from the battery cell from sputtering onto the sampling chip 40.

[0066] In this embodiment, the inner diameter of the second through hole 622 is less than or equal to the inner diameter of the first through hole 621. Since the second through hole 622 corresponds to the first through hole 621, the reduction in the inner diameter of the second through hole 622 is equivalent to reducing the flow area of ​​the airflow. This can block the metal material carried out by the airflow when the valve is opened in the thermally runaway battery cell, thus preventing the metal material from splashing into the sampling chip 40 and the busbar 20.

[0067] In this embodiment, the sum of the thicknesses of the protective member 70 and the sampling chip 40 can be less than the height of the protrusion 520. For example... Figure 1 and Figure 5In the structure, the protrusion 520 can protrude from the surface of the protective member 70, and the upper surface of the protrusion 520 can fit with the upper cover plate so that the airflow channel can be directly connected to the outside of the battery pack, thus preventing the metal material carried out by the airflow when the cell is opened from remaining inside the battery pack.

[0068] In this embodiment, please refer to Figure 1 and Figure 2 The wire harness isolation plate 10 is also provided with a plurality of grooves (not shown), and a plurality of busbar units 211 are embedded in the plurality of grooves. One busbar unit 211 is provided in one groove. The busbar unit 211 can be electrically connected to the corresponding battery cell by laser welding.

[0069] This application also proposes a battery pack, which may include the aforementioned data acquisition integration component 100, multiple battery cells, a module housing, an upper cover plate, and a bottom cover plate. The module housing, upper cover plate, and bottom cover plate enclose a receiving cavity, and the multiple battery cells and the data acquisition integration component 100 are disposed within the receiving cavity.

[0070] In this embodiment, the upper cover is used to protect the upper part of the battery pack. The upper cover can be connected to the data acquisition integration component 100 through plastic rivets and the adhesive layer on the barrier strip. The material of the upper cover can be plastic materials such as PC, PP, and PVC.

[0071] In this embodiment, the bottom cover plate can be an insulating bottom film used to protect the bottom of the battery pack, and the bottom cover plate can be bonded to the bottom surface of the battery cell using double-sided adhesive; the material of the bottom plate 510 can be a film material such as PET or PVC.

[0072] This invention provides a data acquisition integration component and a battery pack. The data acquisition integration component includes a wiring harness isolation plate and a busbar, a flexible circuit board, and a sampling chip disposed on the wiring harness isolation plate. The busbar includes multiple bus groups, and each bus group includes multiple bus units. The flexible circuit board includes multiple transmission strips disposed between adjacent multiple bus units. The sampling chip is disposed between two adjacent bus groups and is electrically connected to the transmission strips. This application integrates the battery management module's circuit board into the data acquisition integration component by setting the sampling chip electrically connected to the transmission strips between the bus groups. This allows the battery cell's working data to be directly transmitted to the sampling chip through the transmission strips, eliminating the need for adapter wire harnesses and solving the technical problem of not being able to arrange a large number of adapter wire harnesses due to space limitations.

[0073] The embodiments of the present invention have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
