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.

[0032] In related technologies, the wiring harness isolation plate of the CCS module in a square power battery is usually made of plastic, which lacks protection during data acquisition. This can lead to signal loss in the event of thermal runaway within the battery cell. The following proposes an integrated data acquisition module and battery pack to address these technical problems.

[0033] Please see Figures 1 to 4 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 protective layer 40.

[0034] In this embodiment, the busbar 20 can be 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 can be 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 310 are disposed between two adjacent busbar units 211.

[0036] In this embodiment, the protective layer 40 can be disposed on the wire harness isolation plate 10. The protective layer 40 includes a plurality of heat insulation strips 410 arranged along the length direction of the wire harness isolation plate 10. The heat insulation strips 410 are disposed between two adjacent busbars 210 and cover the transmission strips 310 located between two adjacent busbars 210.

[0037] This invention provides a data acquisition integrated component 100 and a battery pack. The data acquisition integrated component 100 includes a wire harness isolation plate 10 and a busbar 20, a flexible circuit board 30, and a protective layer 40 disposed on the wire harness isolation plate 10. The busbar 20 includes multiple bus groups 210, each bus group 210 including multiple bus units 211. The flexible circuit board 30 includes multiple transmission strips 310 disposed between adjacent multiple bus units 211. The protective layer 40 includes multiple heat insulation strips 410 disposed between adjacent multiple bus groups 210, with the heat insulation strips 410 covering the transmission strips 310 located between two adjacent bus groups 210. This application protects the transmission strips 310 by providing multiple heat insulation strips 410 covering the transmission strips 310 between multiple bus groups 210, preventing the signal transmission of the transmission strips 310 from being affected when the battery cell experiences thermal runaway, thus ensuring normal signal acquisition.

[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 temperature data and voltage data of the cells in the battery module in order to detect the working status of the cells in real time.

[0039] It should be noted that the data acquisition integration component 100 may also 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, and the voltage and temperature acquisition units can acquire and transmit the voltage data and temperature data of the battery cell 200.

[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 protective layer 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, each of the bus groups 210 may include 16 bus units 211 arranged in a 2x8 pattern.

[0043] It should be noted that the flexible circuit board 30 may include four transmission strips 310, each transmission strip 310 being electrically connected to two adjacent busbar units 211, and each busbar unit 211 being electrically connected to only one transmission strip 310; for example Figure 1 In the structure, each of the transmission bars 310 can be electrically connected to four of the busbar units 211 in one of the busbar 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 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] The protective layer 40 in this application can cover the transmission strip 310 in the flexible circuit board 30, so as to avoid affecting the signal transmission of the transmission strip 310 when the battery cell experiences thermal runaway; however, the protective layer 40 on the wire harness isolation plate 10 is raised, which affects the flatness of the wire harness isolation plate 10.

[0048] Please see Figure 1 and Figure 4 The wire harness isolation plate 10 may also have a plurality of first grooves 110, and the plurality of heat insulation strips 410 are embedded in the plurality of first grooves 110, that is, the plurality of heat insulation strips 410 can be fixed in the first grooves 110.

[0049] In this embodiment, the number of the first grooves 110 can be the same as the number of the heat insulation strips 410, with one heat insulation strip 410 embedded inside each of the first grooves 110; for example... Figure 2 In the structure, the wire harness isolation plate 10 is provided with 6 first grooves 110, and 6 heat insulation strips 410 are embedded in the corresponding wire harness isolation plate 10.

[0050] In this embodiment, since the heat insulation strip 410 needs to cover the transmission strip 310, and the heat insulation strip 410 is located within the corresponding first groove 110, when the heat insulation strip 410 crosses the first groove 110, a portion of the transmission segment of the transmission strip 310 is also embedded within the first groove 110. This portion of the transmission segment of the transmission strip 310 is tightly against the inner wall of the first groove 110, and the heat insulation strip 410 presses against this portion of the transmission segment of the transmission strip 310, thus embedding the heat insulation strip 410 within the first groove 110. For example... Figure 1 In the structure, the heat insulation strip 410 presses together a portion of the transmission section of the four transmission strips 310.

[0051] In this embodiment, since a portion of the transmission section of the transmission strip 310 and the heat insulation strip 410 are provided within the first groove 110, the sum of the thicknesses of the heat insulation strip 410 and the transmission strip 310 can be greater than the depth of the first groove 110. That is, the upper surface of the heat insulation strip 410 will exceed the upper surface of the wire harness isolation plate 10, increasing the blocking height of the blocking strip 420 provided on the heat insulation strip 410. This prevents metal materials from sputtering into the busbars 210 located on both sides of the heat insulation strip 410, thus avoiding the technical problem of short circuits in the series-connected battery cells. In this case, the sum of the thicknesses of the heat insulation strip 410 and the transmission strip 310 can be less than the depth of the first groove 110, so that the heat insulation strip 410 can be embedded in the first groove 110, preventing the heat insulation strip 410 from peeling off. In addition, in order to ensure that the upper surface of the heat insulation strip 410 and the upper surface of the wire harness isolation plate 10 are on the same plane, the depth of the first groove 110 needs to be equal to the sum of the thicknesses of the heat insulation strip 410 and the transmission strip 310. Under the premise of ensuring the fixing and blocking function of the heat insulation strip 410, the flatness of the wire harness isolation plate 10 can be guaranteed.

[0052] In this embodiment, the depth of the first groove 110 is less than the thickness of the wire harness isolation plate 10, and the thickness of the heat insulation strip 410 is 0.8 mm to 1.2 mm. For example, the thickness of the wire harness isolation plate 10 can be 1 mm to 1.5 mm, and the depth of the first groove 110 can be specifically set according to the thickness of the wire harness isolation plate 10. For example, when the thickness of the wire harness isolation plate 10 is 1.5 mm, the depth of the first groove 110 can be 1.2 mm, and the thickness of the heat insulation strip 410 can be 1 mm.

[0053] In this embodiment, the material of the heat insulation strip 410 can be a high-temperature resistant insulating material.

[0054] In related technologies, the battery cell needs a corresponding venting channel to release the airflow released 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 airflow 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.

[0055] Please see Figures 1 to 3 The wire harness isolation plate 10 may have a plurality of first holes 501, which are located in a plurality of first grooves 110. Each heat insulation strip 410 has a plurality of second holes 502 corresponding to the first holes 501, and the orthographic projection of the second hole 502 on the first hole 501 is located in the first hole 501.

[0056] In this embodiment, the plurality of first holes 501 and the plurality of second holes 502 are configured to provide clearance for the airflow ejected from the battery cell when the valve is opened. At the same time, the orthographic projection of the second hole 502 onto the first hole 501 is located within the first hole 501. That is, the opening area of ​​the second hole 502 can be less than or equal to the opening area of ​​the first hole 501. This can block the metal material carried out by the airflow when the battery cell in thermal runaway is opened, preventing the metal material from splashing onto the busbar 20 and improving the risk of short circuit of the series-connected battery cells.

[0057] In this embodiment, the second hole 502 can be formed as an ellipse, with the long side of the ellipse parallel to the heat insulation strip 410 and the short side perpendicular to the heat insulation strip 410. Setting the second hole 502 as an ellipse can reduce the overflow of metal material in the length direction of the wire harness separator 10, so that the metal material carried by the airflow overflows in the length direction of the wire harness separator 10. Since a high-temperature resistant and insulating heat insulation strip 410 is provided in this direction, even if metal material is sputtered on the heat insulation strip 410, the overall impact on the battery module is small.

[0058] In the above embodiments, although the setting of the heat insulation strip 410 can improve the possibility of metal material carried by the airflow splashing onto the busbar 20 when the battery cell valve is opened, it may still splash onto the busbar 20 with the airflow due to the uncertainty of the direction of the airflow ejected from the first hole 501.

[0059] In this embodiment, please refer to Figures 1 to 4The protective layer 40 further includes a plurality of blocking strips 420 disposed on a plurality of heat insulation strips 410. The plurality of blocking strips 420 are arranged along the first direction. Two blocking strips 420 are disposed on one heat insulation strip 410. The extending direction of the blocking strips 420 is the same as the extending direction of the heat insulation strip 410. The two blocking strips 420 are disposed on both sides of the plurality of second holes 502.

[0060] Please refer to 1 to Figure 4 Each of the heat insulation strips 410 is provided with two blocking strips 420. The length of the blocking strip 420 in the width direction of the wire harness isolation plate 10 can be equal to the length of the heat insulation strip 410. The side of each blocking strip 420 can be on the same plane as the side of the heat insulation strip 410.

[0061] In this embodiment, when the metal material is carried out by the airflow inside the battery cell, the blocking strip 420 prevents the metal material from splashing into the busbars 210 located on both sides of the heat insulation strip 410, thus avoiding the technical problem of short circuit in the series-connected battery cells.

[0062] In this embodiment, the thickness of the blocking strip 420 can be greater than or equal to the thickness of the adjacent busbar unit 211. That is, the distance from the top surface of the blocking strip 420 to the bottom surface of the wire harness isolation plate 10 needs to be greater than or equal to the distance from the top surface of the busbar unit 211 to the bottom surface of the wire harness isolation plate 10. Since the blocking strip 420 mainly blocks metal material overflowing from the second hole 502 from sputtering into the busbar 20, if the thickness of the blocking strip 420 is less than the thickness of the adjacent busbar unit 211, metal material may still sputter into the busbar unit 211 due to the height difference. However, when the thickness of the blocking strip 420 is greater than or equal to the thickness of the adjacent busbar unit 211, the blocking strip 420 can further block the sputtered metal material.

[0063] In this embodiment, the blocking strip 420 may be made of a high-temperature resistant insulating material.

[0064] In this embodiment, since the wire harness separator 10 is usually integrated into the top cover of the battery pack, and in the thickness direction of the wire harness separator 10, the two sides of the blocking strip 420 are respectively provided with a first adhesive layer and a second adhesive layer. The blocking strip 420 is bonded to the corresponding heat insulation strip 410 through the first adhesive layer, and the blocking strip 420 is bonded to the target cover through the second adhesive layer. That is, the blocking strip 420 can be bonded to the top cover of the battery pack through the second adhesive layer.

[0065] In this embodiment, the combined structure of the heat insulation strip 410, the two blocking strips 420 and the upper cover plate ensures that the metal material overflowing from the explosion-proof valve of the battery cell is blocked by the upper cover plate and the two blocking strips 420, allowing the metal material to fall onto the corresponding heat insulation strip 410, thus preventing the overflowing metal material from splashing into the busbar 20.

[0066] In related technologies, since battery packs are usually formed by multiple cells connected in series in an array, and the heat dissipation intensity of the cells in the central area of ​​the battery pack is less than that of the cells in the outer area of ​​the battery pack, the operating temperature of the cells in the central area is higher than that of the cells in the outer area. When the explosion-proof valve of the cell is opened, the airflow velocity released by the cells in the central area is greater than that released by the cells in the outer area. Therefore, the busbar 20 corresponding to the cells in the central area is prone to short circuit.

[0067] In this embodiment, in the central area of ​​the acquisition integration component 100, the two blocking strips 420 on the heat insulation strip 410 have a first spacing, and in the peripheral area of ​​the acquisition integration component 100, the two blocking strips 420 on the heat insulation strip 410 have a second spacing, wherein the first spacing is smaller than the second spacing.

[0068] In this embodiment, since the operating temperature of the battery cell in the central area is high, when the explosion-proof valve of the battery cell in the central area is opened, the ejected metal material is fast and at a large angle. This application reduces the distance between the two blocking strips 420 located in the central area, thereby reducing the movement distance of the metal material in the length direction of the wire harness isolation plate 10. This makes the large-angle metal material ejected from the second hole 502 blocked by the blocking plate, thus improving the technical problem that the busbar 20 in the central area is prone to short circuit.

[0069] In this embodiment, please refer to Figure 1 The wire harness isolation plate 10 is also provided with a plurality of second grooves 120, and a plurality of busbar units 211 are embedded in a plurality of second grooves 120. One busbar unit 211 is provided in one second groove 120. The busbar unit 211 can be electrically connected to the corresponding battery cell by laser welding.

[0070] This application also proposes a battery pack, which may include the aforementioned data acquisition integration component 100, multiple battery cells, a module housing, a top cover, and a bottom plate. The module housing, top cover, and bottom plate enclose a receiving cavity, and the multiple battery cells and the data acquisition integration component 100 are disposed within the receiving cavity.

[0071] 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.

[0072] In this embodiment, the base plate can be an insulating base film used to protect the bottom of the battery pack, and the base plate can be bonded to the bottom surface of the battery cell using double-sided adhesive; the material of the base plate can be a film material such as PET or PVC.

[0073] This invention provides a data acquisition integrated component and a battery pack. The data acquisition integrated component includes a wire harness isolation plate and a busbar, a flexible circuit board, and a protective layer disposed on the wire 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 protective layer includes multiple heat insulation strips disposed between adjacent multiple bus groups, and the heat insulation strips cover the transmission strips located between two adjacent bus groups. This application protects the transmission strips by setting heat insulation strips covering the transmission strips between the bus groups, preventing the signal transmission of the transmission strips from being affected when the battery cell experiences thermal runaway, thus ensuring normal signal acquisition.

[0074] 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.
