Insulation components, collection components, battery modules and battery packs

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on May 28, 2024, with application number 202421189975.9. The entire contents of the above application are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of battery technology, and in particular to an insulating component, a collection assembly, a battery module, and a battery pack. Background Art

[0003] In the battery module, an insulating component is provided on one side of the multiple battery cells, and a connecting bar and a collection harness are installed on the insulating component. The connecting bar is configured to be electrically connected to the battery cells, and the collection harness is electrically connected to the connecting bar and is configured to collect voltage, current and other signals. Technical issues

[0004] Typically, a voltage collection bar, such as a nickel sheet, is provided on the collection harness and is configured to collect voltage signals. In related art, after the collection harness and the connecting bar are both installed on the insulating component, the connecting bar is thicker than the collection harness. Therefore, when the voltage collection bar and the connecting bar are electrically connected, the voltage collection bar needs to be bent to a degree that ensures that the voltage collection bar can be electrically connected to the side of the connecting bar that faces away from the insulating component. Therefore, the extended length of the voltage collection bar is relatively long to ensure that the connection area with the busbar after bending meets the design requirements. However, there are a large number of voltage collection bars and connecting bars in a battery module, and the step of bending each voltage collection bar results in a large amount of material used in the voltage collection bar, resulting in increased production costs. Furthermore, the greater the degree of bending of the voltage collection bar, the lower its strength will be, and there may be risks of cracking or breaking when the battery module is subjected to variable loads. Solution

[0005] In a first aspect, an embodiment of the present application provides an insulating component configured to install a connecting row and a collection harness, wherein the connecting row includes a first plate and a second plate connected in a bent manner; the insulating component has a mounting portion and a slot recessed relative to the mounting portion, the mounting portion is configured to install the first plate and the collection harness, the second plate is installed in the slot, and a side of the second plate facing away from the insulating component is closer to the mounting portion than a side of the first plate facing away from the insulating component, the collection harness is provided with a voltage collection strip, and a side of the second plate facing away from the insulating component is configured to install the voltage collection strip.

[0006] In a second aspect, an embodiment of the present application provides a collection assembly, comprising a connection bar, a collection harness, and the insulating component as described above.

[0007] In a third aspect, an embodiment of the present application provides a battery module, comprising a battery cell and the collection assembly as described above, wherein a plurality of battery cells are provided, the collection assembly is located on one side of the plurality of battery cells, and the connecting bar and the collection harness are located on the side of the insulating component facing away from the battery cell.

[0008] In a fourth aspect, an embodiment of the present application provides a battery pack, comprising a box and at least one battery module as described above, wherein the battery module is disposed in the box. Beneficial effects

[0009] The present application provides an insulating component, a collection assembly, a battery module, and a battery pack. When installing a connecting bar and a collection harness on the insulating component, the connecting bar and the collection harness are both installed on the mounting portion of the insulating component, and the second plate of the connecting bar is engaged with a recessed slot on the mounting portion. On the one hand, the engagement of the second plate with the recessed slot can locate the position of the connecting bar, ensuring the secure installation of the connecting bar on the insulating component. On the other hand, after the connecting bar is installed on the insulating component, the side of the second plate facing away from the insulating component is closer to the mounting portion than the side of the first plate facing away from the insulating component, that is, the height of the second plate relative to the mounting portion is lower than the height of the first plate relative to the mounting portion. In this way, the voltage collection bar on the collection harness located on the mounting portion can achieve conductive connection with the second plate of the connecting bar without requiring significant bending or even no bending. Since the voltage collection bar is bent less or even does not require bending, the material usage of the voltage collection bar can be reduced, production costs can be reduced, strength loss of the voltage collection bar can be reduced, the service life of the voltage collection bar can be extended, and the reliability of voltage signal collection can be improved.

[0034] As shown in Figures 1 and 2, this embodiment provides a collection component, including an insulating component 100, a connecting bar 200, a collection harness 300, and a temperature collection component 400. The connecting bar 200, the collection harness 300, and the temperature collection component 400 are installed on the insulating component 100, so that the entire collection component forms a whole, and the connecting bar 200 is configured to be electrically connected to the battery cell, and the connecting bar 200 and the temperature collection component 400 are both communicatively connected to the collection harness 300 to collect the voltage signal and temperature signal of the battery cell. During the assembly of the battery module, the entire collection component is loaded as a whole, which can improve the assembly efficiency. The collection component provided in this embodiment can avoid the defect of large collection accuracy error due to deformation of the insulating component 100, and after the collection harness 300 is installed, it can avoid the phenomenon of the collection harness 300 falling off in subsequent processes.

[0035] As shown in Figures 3 and 4, it is a schematic structural diagram of the insulating component 100 provided in this embodiment. The insulating component 100 has a mounting portion 1 and a card slot 22 that is recessed relative to the mounting portion 1. In conjunction with Figures 2 and 5, the connecting row 200 includes a first plate 210 and a second plate 220 that are bent and connected. After the entire connecting row 200 is installed on the insulating component 100, the heights of the first plate 210 and the second plate 220 are inconsistent. The mounting portion 1 is configured to install the first plate 210 and the collection harness 300, and the second plate 220 is installed in the card slot 22. The side of the second plate 220 facing away from the insulating component 100 is closer to the mounting portion 1 of the insulating component 100 than the side of the first plate 210 facing away from the insulating component 100. The voltage collection harness 300 is exemplarily a flexible printed circuit (FPC) on which a voltage collection strip 310 is mounted. Referring to Figures 2, 5, and 6, the side of the second plate 220 facing away from the insulating component 100 is configured to accommodate the voltage collection strip 310. The voltage collection strip 310 is electrically connected to the second plate 220, for example, by laser welding.

[0036] When installing the connecting bar 200 and the collecting harness 300 on the insulating component 100 , both the connecting bar 200 and the collecting harness 300 are mounted on the mounting portion 1 of the insulating component 100 , and the second plate 220 of the connecting bar 200 is engaged with the slot 22 recessed on the mounting portion 1 . On the one hand, the engagement of the second plate 220 with the card slot 22 can locate the position of the connecting bar 200, ensuring the stable installation of the connecting bar 200 on the insulating component 100; on the other hand, after the connecting bar 200 is installed on the insulating component 100, the side of the second plate 220 facing away from the insulating component 100 is closer to the mounting portion 1 than the side of the first plate 210 facing away from the insulating component 100, that is, the height of the second plate 220 relative to the mounting portion 1 is lower than the height of the first plate 210 relative to the mounting portion 1, and the voltage collection bar 310 on the collection harness 300 located on the mounting portion 1 does not need to be bent to a large extent or even does not need to be bent to achieve conductive connection with the second plate 220 of the connecting bar 200. Since the bending degree of the voltage collection bar 310 is reduced or even does not need to be bent, the material usage of the voltage collection bar 310 can be reduced, the production cost can be reduced, the strength loss of the voltage collection bar 310 can be reduced, the service life of the voltage collection bar 310 can be extended, and the reliability of voltage signal collection can be improved.

[0037] Referring to Figure 6 , the depth of the slot 22 is designed to be roughly the same as the thickness of the second plate 220. Because the depth of the slot 22 is roughly the same as the thickness of the second plate 220, once the second plate 220 is inserted into the slot 22, its top surface is flush with the mounting portion 1. This allows the voltage collection strip 310 of the collection harness 300 on the mounting portion 1 to achieve an electrically conductive connection with the second plate 220 of the connection bar 200 without bending. This eliminates the need to bend the voltage collection strip 310 during assembly of the collection assembly, improving production efficiency, reducing costs, and facilitating mass production.

[0038] Exemplarily, the voltage collection bar 310 is a nickel bar, which has good electrical conductivity and is relatively low cost. In some embodiments, the first plate 210 and second plate 220 of the connecting bar 200 are integrally stamped, creating a smooth transition at the junction to prevent disconnection due to stress concentration. The connecting bar 200 can be made of aluminum or copper, as long as it has good electrical conductivity.

[0039] In some embodiments, the mounting portion 1 is recessed with a connecting row main groove 21 and a wiring harness groove 3 that are interconnected. The connecting row main groove 21 is engaged with the first plate body 210. The engaging groove 22 is at least partially recessed in the bottom wall of the connecting row main groove 21. The wiring harness groove 3 is configured to accommodate the collection wiring harness 300.

[0040] The connecting bar main groove 21 and the aforementioned latching groove 22 constitute the connecting bar mounting groove 2. One connecting bar mounting groove 2 is provided on the insulating component 100 for each connecting bar 200. The connecting bar main groove 21 of the connecting bar mounting groove 2 is configured to latch the first plate 210 of the connecting bar 200, while the latching groove 22 of the connecting bar mounting groove 2 is configured to latch the second plate 220 of the connecting bar 200. This ensures the secure installation of the entire connecting bar 200 and effectively limits the position of the connecting bar 200.

[0041] The provision of a harness groove 3 configured to accommodate the collection harness 300 prevents other components from contacting or pulling the collection harness 300, effectively protecting and limiting the collection harness 300 and preventing it from falling off. Because the collection harness 300 remains stable and secure, failure of the voltage and temperature collection locations due to pulling can be avoided.

[0042] The height difference between the bottom wall of the connecting row main groove 21 and the bottom wall of the wiring harness groove 3 is less than or equal to 2.5mm. That is, the bottom wall of the connecting row main groove 21 and the bottom wall of the wiring harness groove 3 can be flush, simplifying the process. The bottom wall of the connecting row main groove 21 and the bottom wall of the wiring harness groove 3 can also be uneven, but have a certain height difference. This height difference is exemplarily greater than or equal to 1.5mm and less than or equal to 2.5mm to avoid excessive deformation of the insulating component 100 during integral molding. For example, the height difference is 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2.0mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, etc.

[0043] In other embodiments, the connecting row main groove 21 and the harness groove 3 may not be provided, and only the above-mentioned card groove 22 may be directly recessed on the upper surface of the insulating component 100 .

[0044] Referring to FIG4 , a first step structure 211 is provided on the wall of the connecting bar main groove 21, and referring to FIG7 , a second step structure 230 is provided on the connecting bar 200. The first step structure 211 and the second step structure 230 interlock together to help improve the stability of the connecting bar 200 within the connecting bar mounting groove 2. Furthermore, the first step structure 211 and the second step structure 230 provide a foolproof function, preventing the connecting bar 200 from being installed in the wrong position.

[0045] 4 , the groove wall of the connecting row main groove 21 includes a first step surface 1 2111, a first step surface 2112, and a first step surface 3 2113, which are sequentially connected in a Z-shape. For example, the first step surface 1 2111, the first step surface 2112, and the first step surface 3 2113 can be sequentially connected vertically to form the aforementioned first step structure 211. For example, the side wall of the connecting row 200 includes a second step surface 1 231, a second step surface 232, and a second step surface 3 233, which are sequentially connected in a Z-shape. For example, the second step surface 1 231, the second step surface 232, and the second step surface 3 233 can be sequentially connected vertically to form the aforementioned second step structure 230. As shown in Figure 5, this is a schematic diagram of the first step structure 211 and the second step structure 230 after being interlocked, wherein the first step surface 1 2111 and the second step surface 1 231 are in contact with each other, the first step surface 2112 and the second step surface 232 are in contact with each other, and the first step surface 3 2113 and the second step surface 3 233 are in contact with each other.

[0046] Referring to Figures 1 and 2 , the insulating component 100 is provided with multiple connection bars 200, distributed on both sides of the collection harness 300. Two connection bars 200 at the ends are configured to connect to other battery modules or output externally. These two connection bars 200 are provided with connection ears 250, which are configured to connect to external leads to achieve communication with other battery modules.

[0047] 2 , 8 and 9 , a limiting groove 240 is provided on the connecting row 200 having a connecting ear 250 , and correspondingly, a latching protrusion 212 is provided on the side wall of the connecting row mounting slot 2 in which the connecting row 200 is mounted. The latching protrusion 212 engages with the above-mentioned limiting groove 240 to improve the installation stability of the connecting row 200 .

[0048] 4 and 5 , at least one fixing post 4 is protruding from the bottom wall of the main groove 21 of the connecting row. Referring to FIG. 7 , a fixing hole 260 is provided on the first plate 210 of the connecting row 200. The fixing post 4 is passed through the fixing hole 260 of the first plate 210 to improve the installation firmness of the connecting row 200 and prevent the connecting row 200 from moving after installation.

[0049] In some embodiments, the fixing column 4 is a hot-riveted column. After the fixing column 4 passes through the fixing hole 260, the head of the fixing column 4 is hot-melted to form a hot-riveted head that stops the connecting row 200, thereby preventing the connecting row 200 from moving along its own thickness direction to disengage from the connecting row mounting groove 2.

[0050] Referring to Figures 4 and 5 , at least three fixing posts 4 are provided (three in each case), arranged in a triangular pattern. This arrangement helps improve the stability of the connection bar 200. Furthermore, the three triangularly arranged fixing posts 4 form a foolproof design that prevents incorrect installation of the connection bar 200.

[0051] Alternatively, referring to Figures 8 and 9, two fixing holes 260 are provided on the first plate body 210 of the connecting row 200 with connecting ears 250, and two fixing columns 4 are provided on the bottom wall of the corresponding connecting row main groove 21. The two fixing columns 4 are plugged into the two fixing holes 260 in a one-to-one correspondence, and the two fixing columns 4 are arranged diagonally relative to the first plate body 210. While ensuring that the connecting row 200 is firmly fixed, the number of fixing columns 4 can be reduced as much as possible.

[0052] In other embodiments, the number of fixing columns 4 can be set as needed under the premise of satisfying the fixing firmness of the connecting bar 200. The number and distribution of the fixing columns 4 are not limited here.

[0053] In some embodiments, referring to Figures 3, 4 and 5, the card slot 22 extends from the main slot 21 of the connecting bar to the wiring harness groove 3. Correspondingly, referring to Figure 7, the second plate body 220 extends an extension section relative to the side wall of the first plate body 210, so that the second plate body 220 of the connecting bar 200 extends to the inside of the wiring harness groove 3 after installation, so as to be as close as possible to the collection harness 300, ensuring that the second plate body 220 and the voltage collection bar 310 can fully contact each other, making laser welding of the second plate body 220 and the voltage collection bar 310 more convenient and increasing the flow area.

[0054] 2 , 3 and 10 , a temperature collection component groove 5 is recessed on the insulating component 100 , and the temperature collection component groove 5 is configured to engage with the temperature collection component 400 to fix the installation position of the temperature collection component 400 on the insulating component 100 , thereby preventing the temperature collection component 400 from being pulled by the collection harness 300 and moving, causing the temperature collection point between the temperature collection component 400 and the battery to fail, thereby ensuring the temperature collection effect.

[0055] In some embodiments, the temperature sampling component recess 5 is recessed in the mounting portion 1. The temperature sampling component 400 includes a mounting bracket 410 and a temperature sensing module 420 mounted on the mounting bracket 410. The temperature sampling component recess 5 is configured to engage the mounting bracket 410. The temperature sensing module 420 is mounted on the mounting bracket 410. The temperature sensing module 420 is communicatively connected to the data acquisition harness 300, for example, via a wiring harness connection or welding, to achieve temperature signal acquisition. Engaging the mounting bracket 410 in the temperature sampling component recess 5 ensures that the temperature sampling component 400 is securely mounted while exposing the temperature sensing module 420 for connection to the data acquisition harness 300.

[0056] Referring to Figure 3, a temperature sampling hole 6 is provided through the bottom wall of the temperature sampling component groove 5. At the same time, a through-hole is also provided on the mounting bracket 410. The temperature sensing module 420, the through-hole, the temperature sampling hole 6 and the temperature sampling point on the battery cell are arranged opposite each other. Thermal conductive structural glue is poured into the through-hole and the temperature sampling hole 6, so that the temperature sensing module 420 can contact the temperature sampling point on the battery cell through the thermal conductive structural glue, thereby realizing accurate temperature sampling of the battery cell.

[0057] For example, the temperature sensing module 420 is a temperature sensor that can accurately collect temperature and is easily connected to the temperature collection harness 300 .

[0058] Referring to Figures 3 and 11 , multiple connecting row main grooves 21 are provided on both sides of the wiring harness groove 3 . These multiple connecting row main grooves 21 correspond to the first plates 210 of the multiple connecting rows 200 , ensuring that each connecting row 200 is effectively secured. The multiple connecting row main grooves 21 on both sides of the wiring harness groove 3 are staggered to avoid excessively weak areas in the width direction of the insulating component 100 , thereby improving the overall strength of the insulating component 100 and ensuring a more balanced strength distribution throughout the insulating component 100 .

[0059] In some embodiments, the insulating component 100 is integrally formed using a vacuum forming process. Figure 12 illustrates the back of the insulating component 100 after vacuum forming. This integral vacuum forming process of the insulating component 100 facilitates manufacturing, reduces costs, and facilitates mass production. For example, the insulating component 100 is made of polycarbonate (PC), which offers high strength, preventing it from being weakened after vacuum forming.

[0060] In other embodiments, the above-mentioned connection row main groove 21, the card groove 22, the wiring harness groove 3 and the temperature collection component groove 5 can also be formed through a later grooving process.

[0061] Referring to FIG. 13 , in some embodiments, the thickness D of the insulating component 100 is greater than or equal to 4 mm and less than or equal to 15 mm. For example, the thickness D of the insulating component 100 is 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, etc. In this embodiment, the thickness D of the insulating component 100 is 6 mm. While ensuring that the fixing column 4, the connection bar mounting groove 2, the wiring harness groove 3, and the temperature collection component groove 5 formed on the insulating component 100 can firmly limit the connection bar 200, the collection harness 300, and the temperature collection component 400, it can also prevent the material of the insulating component 100 from being overstretched during the blister molding process, thereby preventing the insulating component 100 from being locally weakened or even broken due to excessive stretching during the blister molding process.

[0062] 11 and 12 , a battery connection hole 7 is provided on the bottom wall of the connecting bar main slot 21 , through which the connecting bar 200 is connected to the battery cell pole.

[0063] This embodiment also provides a battery module comprising battery cells and the aforementioned data acquisition assembly. Multiple battery cells are provided, and the data acquisition assembly is located on one side of the multiple battery cells. The connection bar 200 and data acquisition harness 300 are located on the side of the insulating component 100 facing away from the battery cells. The data acquisition assembly can collect voltage and temperature signals from multiple battery cells, enabling monitoring of the battery cells.

[0064] This embodiment also provides a battery pack, including a box and at least one battery module as described above. The battery module is arranged in the box. The box can be installed on an electrical device, such as a vehicle. The battery pack box can be installed on the beam frame of the vehicle.

[0065] The advantages of the battery module having the above-mentioned acquisition component and the battery pack having the battery module are as described above and will not be elaborated here.
