Description

Technical Field

[0001] This application relates to the field of energy storage technology, specifically to a wire harness board assembly and a battery module. Background Technology

[0002] In related technologies, wire harness board assemblies (CCS assemblies) typically include support components, conductive components, and signal acquisition components. In these technologies, conductive components are usually fixed to the support components by means of fusion welding, adhesive bonding, or welding. This can lead to difficulties in separating the conductive components from the support components after damage to the conductive components or support components, ultimately resulting in excessively high maintenance costs for wire harness board assemblies. Utility Model Content

[0003] The embodiments of this application provide a wiring harness board assembly and a battery module, which can improve the technical problem of excessively high maintenance costs of wiring harness board assemblies.

[0004] In a first aspect, this application provides a wire harness board assembly, comprising: A support component, wherein a mounting groove is provided on the support component; The conductive component has a positioning through hole on one of the mounting groove and the conductive component itself, and a positioning protrusion on the other. Both the positioning through hole and the positioning protrusion extend along the height direction of the wire harness board assembly. The positioning protrusion engages with the positioning through hole to fix the conductive component in the mounting groove. This design avoids the time-consuming and laborious process of disassembling the conductive component and support components, reducing the maintenance cost of the wire harness board assembly.

[0005] In some embodiments, the positioning through hole includes an oblong hole, and the positioning protrusion includes a circular positioning post; Wherein, the maximum length L of the oblong hole is greater than or equal to the diameter D of the circular positioning post; and / or, The minimum length M of the oblong hole is less than the diameter D of the circular positioning post. This design avoids manufacturing tolerances in the conductive or supporting components that could prevent the conductive component from being installed on the supporting component. Furthermore, the interference fit improves the stability of the connection between the supporting component and the conductive component.

[0006] In some embodiments, the circular positioning post is disposed within the mounting groove, and the oblong hole is disposed within the conductive element; The maximum length L of the oblong hole and the diameter D of the circular positioning post satisfy the following relationship: 0 < L ≤ 3 mm. This design can, to some extent, eliminate the influence of tolerances on conductive or supporting components, and avoid the problem of reducing the conductivity of conductive components due to an excessively large oblong hole.

[0007] In some embodiments, the conductive element includes a plurality of conductive elements, and the positioning through hole is provided on a first end and a second end of some of the conductive elements along their own length direction; The mounting grooves include multiple grooves, which are spaced apart along the length of the support component. At least two positioning protrusions are formed within some of the mounting grooves. One of the at least two positioning protrusions is adapted to the positioning through-hole at the first end of the conductive component, and the other is adapted to the positioning through-hole at the second end of the conductive component. This arrangement improves the connection stability of the conductive component.

[0008] In some embodiments, the support member is provided with support protrusions, and adjacent mounting grooves are separated by the support protrusions along the length direction of the support member. This arrangement not only improves the structural strength of the support member but also prevents direct contact between conductive components in adjacent mounting grooves.

[0009] In some embodiments, the conductive element includes a positive electrode section, a raised section, and a negative electrode section connected in sequence. At least one of the positive electrode section and the negative electrode section is fixed to the mounting groove, and the raised section protrudes from the bottom surface of the mounting groove. This configuration avoids excessive external force exerted by the battery cell on the conductive element after the battery cell expands, which could damage the conductive element.

[0010] In some embodiments, the maximum height H of the protruding section protruding from the bottom surface of the mounting groove satisfies the relationship: 0 < H ≤ 3 mm. This arrangement provides a certain buffer space between the protruding section and the bottom surface of the mounting groove, preventing excessive contact area between the protruding section and the supporting component, which could lead to damage to the protruding section.

[0011] In some embodiments, the protrusion is provided with a plurality of mounting through holes spaced apart, and the mounting through holes extend along the height direction of the wire harness board assembly; The wiring harness assembly also includes a temperature monitoring element, which is detachably and selectively connected to one of the plurality of mounting through holes. This arrangement improves the flexibility of the wiring harness assembly.

[0012] In some embodiments, the conductive element includes a plurality of conductive elements, which are spaced apart along the length direction of the support member; The wiring harness assembly also includes a signal acquisition component, which is electrically connected to multiple conductive elements. The signal acquisition component is used at least to acquire the pressure of the conductive elements. This configuration allows the degree of expansion of the battery cell to be determined by the pressure applied by the battery cell to the conductive elements.

[0013] In some embodiments, the signal acquisition component includes a signal transmission cable and a monitoring cable. The monitoring cable comprises multiple cables connected between the signal transmission cable and the conductive element, with one monitoring cable used to monitor two conductive elements. This configuration can reduce the manufacturing cost of the wire harness assembly to some extent.

[0014] In some embodiments, the support member has a clearance through hole that extends along the height direction of the wire harness assembly and is used to avoid the explosion-proof valve on the battery cell.

[0015] Secondly, this application also provides a battery module, the battery module including the wiring harness assembly. In some embodiments, the battery module includes N1 battery cells, and the wiring harness assembly has N2 mounting holes, wherein N1 and N2 satisfy the relationship: N1:N2 = 1:1 - 1:3; and / or, The battery module includes N1 cells, and the wiring harness board assembly is provided with N3 voltage sampling ports, wherein N1 and N3 satisfy the relationship: N1:N3=1:1-1:3.

[0016] Unlike related technologies, in this application, when assembling the support component and the conductive component, the conductive component is first placed in the mounting groove, which provides a certain degree of restraint for the conductive component. Then, the conductive component is fixed within the mounting groove by engaging with the positioning through hole. When maintenance of the support component or the conductive component is required, simply removing the engagement between the positioning protrusion and the positioning through hole allows the conductive component to be separated from the support component, facilitating maintenance of both.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, 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.

[0021] In related technologies, since conductive components and supporting components are usually connected by adhesive bonding, welding, or fusion, when the conductive component or supporting component is damaged, maintenance personnel need to destroy the adhesive layer, weld, or fusion layer between the conductive component and the supporting component in order to separate the conductive component from the supporting component. This will result in excessively high maintenance costs for CCS components.

[0022] To address the problems existing in the relevant technologies, please refer to the appendix. Figures 1 to 3As shown, this application provides a battery module (not shown in the figure), which includes a wiring harness assembly 1, an end plate, an insulating plate, and multiple battery cells. The multiple battery cells are connected in series through the wiring harness assembly 1, the end plate is disposed on both sides of the multiple battery cells, and the insulating plate covers the top of the wiring harness assembly 1. In this application, the wiring harness assembly 1 includes a support member 10 and a conductive member 20.

[0023] The support component 10 is provided with a mounting groove 101. A positioning through hole 201 is provided on one of the mounting groove 101 and the conductive component 20, and a positioning protrusion 1011 is provided on the other. Both the positioning through hole 201 and the positioning protrusion 1011 are along the height direction of the wire harness assembly 1 (as shown in the attached figure). Figure 8 Extending in the Z direction, the positioning protrusion 1011 engages with the positioning through hole 201 to fix the conductive component 20 in the mounting groove 101.

[0024] Specifically, in this embodiment, when assembling the support component 10 and the conductive component 20, the conductive component 20 is first placed in the mounting groove 101. The mounting groove 101 can limit the conductive component 20 to a certain extent. Then, the positioning through hole 201 engages with the mounting groove 101, thereby fixing the conductive component 20 within the mounting groove 101. When maintenance is required on the support component 10 or the conductive component 20, it is only necessary to remove the engagement between the positioning protrusion 1011 and the positioning through hole 201 to separate the conductive component 20 from the support component 10, facilitating maintenance of both components. Compared with related technologies, since the support component 10 and the conductive component 20 do not require adhesive bonding, welding, or fusion, the conductive component 20 can be separated from the support component 10 without complex methods.

[0025] In some embodiments, the support component 10 includes a vacuum-formed bracket, i.e., the vacuum-formed bracket is manufactured using a vacuum forming process, while related technologies typically use injection-molded brackets, i.e., manufactured using an injection molding process. Compared with injection-molded brackets of related technologies, the vacuum-formed bracket can significantly reduce the manufacturing cost of the wire harness assembly 1. Furthermore, using a vacuum-formed bracket on the wire harness assembly 1 can reduce the weight of the wire harness assembly 1 to some extent. In some embodiments, the conductive component 20 can be a copper busbar, aluminum busbar, copper alloy busbar, or aluminum alloy busbar, preferably a copper busbar or an aluminum busbar.

[0026] It is understood that both the conductive component 20 and the blister pack may have certain manufacturing errors. If the manufacturing error of the conductive component 20 or the blister pack is large, the conductive component 20 may not be able to be installed on the blister pack. Therefore, in some embodiments, such as Figure 4 and Figure 5As shown, the positioning through hole 201 includes an oblong hole 2011, and the positioning protrusion 1011 includes a circular positioning post 10111. The maximum length L of the oblong hole 2011 is greater than or equal to the diameter D of the circular positioning post 10111.

[0027] In other words, by designing the positioning through hole 201 as an oblong hole 2011 and the positioning protrusion 1011 as a circular positioning post 10111, and when the maximum length L of the oblong hole 2011 is greater than or equal to the diameter D of the circular positioning post 10111, the circular positioning post 10111 can have a certain stroke in the oblong hole 2011. That is, the existence of this stroke can, to a certain extent, offset the manufacturing errors of the conductive component 20 and the blister bracket.

[0028] In some embodiments, the minimum length M of the oblong hole 2011 is less than the diameter D of the circular positioning post 10111. That is, the circular positioning post 10111 is engaged in the oblong hole 2011 by an interference fit to improve the connection stability between the conductive element 20 and the support member 10.

[0029] In some embodiments, a circular positioning post 10111 is disposed within the mounting groove 101, and an oblong hole 2011 is disposed within the conductive element 20. The maximum length L of the oblong hole 2011 and the diameter D of the circular positioning post 10111 satisfy the relationship: 0 < LD ≤ 3 mm. When LD satisfies this relationship, the maximum length L of the oblong hole 2011 will not be excessively long, effectively preventing a decrease in the conductivity of the conductive element 20 due to its small area. Simultaneously, the excessive length L of the oblong hole 2011 also prevents the conductive element 20 from having insufficient structural strength. However, if LD is greater than 3 mm, the conductive element 20 may have an excessively small area, ultimately resulting in insufficient conductivity and structural strength. In this embodiment, the value of LD can be 0.5 mm, 1 mm, 1.5 mm, 2.0 mm, 2.5 mm, or 3 mm, etc.

[0030] In some embodiments, the conductive element 20 includes a plurality of conductive elements 20, and each of the first and second ends of a portion of the conductive element 20 along its own length direction is provided with a positioning through hole 201. The mounting groove 101 includes a plurality of mounting grooves 101, which are arranged along the length direction of the support member 10 (as shown in the attached figure). Figure 2 In the X direction, the mounting groove 101 is provided with at least two positioning protrusions 1011. Among the at least two positioning protrusions 1011, one of them is adapted to the positioning through hole 201 at the first end of the conductive element 20, and the other is adapted to the positioning through hole 201 at the second end of the conductive element 20.

[0031] like Figure 6 and Figure 7As shown, the conductive component 20 includes a first conductive component 21 for connecting the battery cells in series, and a second conductive component 22 for connecting the battery cells to other external components. In this embodiment, the first conductive component 21 is installed in a mounting groove 101 having at least two positioning protrusions 1011. This design improves the connection stability of the first conductive component 21 and avoids the problem that the first conductive component 21 may rotate within the mounting groove 101 or lift up under the action of external force, which would be caused by the first conductive component 21 being connected to the mounting groove 101 through only one positioning protrusion 1011. The positioning through hole 201 at one end of the second conductive component 22 is used to connect with the positioning protrusion 1011 in the mounting groove 101, and the positioning through hole 201 at the other end is used to connect with other external components.

[0032] In some embodiments, the support member 10 is provided with a support protrusion 11, and along the length direction of the support member 10, two adjacent mounting grooves 101 are separated by the support protrusion 11.

[0033] Specifically, the design of the support protrusion 11 can separate the conductive components 20 in two adjacent mounting grooves 101, thereby preventing the two conductive components 20 from directly contacting each other and causing a short circuit in the battery module. At the same time, since the support component 10 uses a vacuum-formed bracket, the structural strength of the vacuum-formed bracket is relatively low. Therefore, setting the support protrusion 11 between two adjacent mounting grooves 101 can improve the structural strength of the vacuum-formed bracket.

[0034] In some embodiments, the conductive element 20 includes a positive electrode segment 211, a protruding segment 212, and a negative electrode segment 213 connected in sequence. At least one of the positive electrode segment 211 and the negative electrode segment 213 is fixed to the mounting groove 101, and the protruding segment 212 protrudes from the bottom surface of the mounting groove 101.

[0035] Specifically, when the conductive element 20 is the first conductive element 21, the positive terminal 211 of the first conductive element 21 is used to connect to the positive terminal of one battery cell, and the negative terminal 213 of the first conductive element 21 is used to connect to the negative terminal of another battery cell, thereby connecting two battery cells in series through one conductive element 20. When the conductive element 20 is the second conductive element 22, the negative terminal 213 or the positive terminal 211 of the second conductive element 22 protrudes from the mounting groove 101 for connection with other external components. In addition, since the battery cell may expand when heated, it may cause the blister pack to deform, ultimately damaging the conductive element 20. Therefore, the conductive element 20 in this embodiment is also provided with a protruding section 212, which protrudes from the bottom surface of the mounting groove 101. When the blister pack deforms, there is a certain buffer space between the protruding section 212 and the blister pack, which can, to a certain extent, prevent the blister pack from applying excessive external force to the conductive element 20, thus avoiding damage to the conductive element 20.

[0036] In some embodiments, see Figure 8 As shown, the maximum height H of the protruding section 212 protruding from the bottom surface of the mounting groove 101 satisfies the relationship: 0 < H ≤ 3 mm. When the maximum height H of the protruding section 212 protruding from the bottom surface of the mounting groove 101 satisfies the above relationship, there is a buffer space between the protruding section 212 and the bottom surface of the mounting groove 101, which can prevent the contact area between the blister bracket and the conductive component 20 from being too large after deformation, thus avoiding the problem of deformation of the conductive component 20. However, when H is greater than 3 mm, it may cause the CCS component to occupy too much space in the height direction. In this embodiment, the value of H can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, and 3 mm.

[0037] In some embodiments, the protrusion 212 is provided with a plurality of mounting through holes 2121 spaced apart, the mounting through holes 2121 extending along the height direction of the wire harness assembly 1. The wire harness assembly 1 also includes a temperature monitoring element (not shown in the figure), the temperature monitoring element being detachably and selectively connected to one of the plurality of mounting through holes 2121.

[0038] In this embodiment, since the protruding section 212 has multiple mounting through holes 2121, the temperature monitoring element can be installed at a location that suits the specific environment, improving the flexibility of the CCS assembly. Simultaneously, because the temperature monitoring element is mounted on the protruding section 212, when the battery cell expands and causes the blister pack to deform, there is a certain buffer space between the protruding section 212 and the blister pack, preventing interference between the temperature monitoring element and the blister pack.

[0039] In some embodiments, two adjacent series-connected conductive elements 20 are monitored by a single temperature monitoring element. That is, the temperature of two adjacent series-connected cells can be monitored by a single temperature monitoring element. Since the current in two adjacent series-connected cells is almost the same, their heat generation is also similar, and their temperature data can be approximately the same. This design reduces the number of temperature monitoring elements on the CCS module, thereby reducing the manufacturing cost of the CCS module to some extent.

[0040] In some embodiments, the conductive element 20 includes a plurality of conductive elements 20, which are spaced apart along the length direction of the support member 10; the wire harness assembly 1 also includes a signal acquisition component 30, which is electrically connected to the plurality of conductive elements 20, and the signal acquisition component 30 is used at least to acquire the pressure of the conductive elements 20.

[0041] Specifically, since the battery cell expands when heated, it is necessary to monitor the degree of expansion of the battery cell in real time. It can be understood that the greater the degree of expansion of the battery cell, the greater the pressure exerted by the battery cell on the conductive component 20. Therefore, the degree of expansion of the battery cell can be obtained by monitoring the pressure on the conductive component 20, thereby avoiding excessive expansion of the battery cell and damage to the battery module.

[0042] In some embodiments, the signal acquisition component 30 includes a signal transmission cable 31 and a monitoring cable 32. Multiple monitoring cables 32 are connected between the signal transmission cable 31 and the conductive element 20, and one monitoring cable 32 is used to monitor two conductive elements 20. Similarly, this design significantly reduces the manufacturing cost of the CCS component compared to a design where each conductive element 20 requires its own monitoring cable 32.

[0043] In some embodiments, the support member 10 has a clearance through hole 12 extending along the height direction of the wire harness assembly 1. The clearance through hole 12 is used to avoid the explosion-proof valve on the battery cell. Unlike related technologies, where the clearance through hole 12 is often manufactured through post-processing, the clearance through hole 12 in this embodiment is formed by blow molding of the blow-molded bracket. In some embodiments, the monitoring cable 32 can be connected to the conductive member 20 by adhesive bonding and welding. Furthermore, in some embodiments, a monitoring cable 32 is provided on each of the second conductive members 22.

[0044] In addition, in some embodiments, the battery module includes N1 cells and the wiring harness assembly 1 is provided with N2 mounting through holes 2121, wherein N1 and N2 satisfy the relationship: N1:N2=1:1-1:3.

[0045] Specifically, when N1:N2 is 1:1, one battery cell corresponds to one mounting hole 2121. When temperature sensing elements are installed on all mounting holes 2121, each temperature sensing element corresponds to one battery cell, enabling accurate temperature measurement of each battery cell. When N1:N2 is 1:2 or 1:3, one temperature sensing element corresponds to two or three battery cells. One advantage of this is reducing the production cost of the wire harness assembly 1.

[0046] In some embodiments, the battery module includes N1 battery cells, and the wiring harness assembly 1 is provided with N3 voltage sampling ports, wherein N1 and N3 satisfy the relationship: N1:N3 = 1:1 to 1:3. The voltage sampling ports are used to connect monitoring cables 32. Similarly, when N1:N3 is 1:1, each monitoring cable 32 corresponds one-to-one with each battery cell, enabling accurate measurement of the voltage of each battery cell. When N1:N2 is 1:2 or 1:3, the number of monitoring cables 32 can be reduced, thereby reducing the production cost of the wiring harness assembly 1 to a certain extent.

[0047] In summary, the wiring harness assembly 1 and the battery module of this application have at least the following beneficial effects: (1) By designing the mounting groove 101, the positioning through hole 201 and the positioning protrusion 1011, the conductive component 20 is easy to assemble with the support component 10, thereby reducing the maintenance cost of the CCS component.

[0048] (2) The positioning through hole 201 is set as a waist-shaped hole 2011 and the positioning protrusion 1011 is a circular positioning post 10111. The circular positioning post 10111 can move in the waist-shaped hole 2011, so that when assembling the conductive part 20 and the support part 10, the influence of manufacturing errors of the conductive part 20 and the support part 10 can be avoided to a certain extent.

[0049] (3) A support protrusion 11 is provided between two adjacent mounting grooves 101, which improves the structural strength of the support component 10 and avoids direct contact between the conductive components 20 in the two adjacent mounting grooves 101.

[0050] (4) The conductive component 20 includes a raised section 212, and a plurality of mounting through holes 2121 are provided on the raised section 212. The temperature monitoring element is detachable and can be selectively connected to one of the plurality of mounting through holes 2121. This configuration improves the flexibility of the CCS assembly.

[0051] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. 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 this application. Therefore, the content of this specification should not be construed as a limitation of this application.
