Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an integrated busbar assembly and a battery. Background Technology

[0002] In the manufacturing process of lithium-ion battery modules, the top pressure strip of the battery cell is a key structural component. It not only plays an important role in fixing the position of the battery cell, but also needs to ensure the precise alignment of the battery cell terminals and connectors. Its assembly quality directly affects the overall structural stability and safety of the battery module.

[0003] Currently, the assembly of pressure strips mainly relies on customized positioning fixtures. For example, pressure strip auxiliary fixtures need to cooperate with positioning posts through positioning holes. Although the operation is convenient, the positioning accuracy is poor. While high-precision pressure block fixtures improve the positioning effect, their complex structure makes operation inconvenient and the cost is high, making it difficult to meet the requirements of high efficiency and high precision at the same time. In addition, the inspection after the pressure strip assembly mainly relies on manual visual inspection and manual testing. However, due to the obstruction of some areas of the pressure strip or its complex structure, it is difficult to intuitively judge whether it is installed in place, which easily leads to missed inspections of defective assembly and affects the long-term reliability of the battery module.

In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model.

[0041] Please combine Figures 1 to 9 This embodiment provides an integrated busbar assembly 1, which is used to connect at least one battery cell group (not shown in the figure). The battery cell group includes multiple battery cells (not shown in the figure). The integrated busbar assembly 1 includes an integrated busbar 10 and a pressure bar 20. The integrated busbar 10 is used to realize the electrical connection between the multiple battery cells. The pressure bar 20 is installed on the integrated busbar 10 and is used to press against the corresponding battery cell, thereby applying a constraint to the battery cell.

[0042] It is understood that in this embodiment, by installing the pressure strip 20 onto the integrated busbar 10, the pressure strip 20 and the integrated busbar 10 are integrated into a single structure. The pressure strip 20 can be precisely positioned directly using the integrated busbar 10, enabling the integrated busbar 10 to achieve both electrical connection and mechanical fixation between the battery cells. In other words, the integrated busbar assembly 1 has both electrical connection and mechanical fixation functions, thereby eliminating the need for dedicated positioning fixtures required for assembling the pressure strip 20 in related technologies, reducing production costs and assembly complexity. At the same time, it avoids surface damage to the pressure strip 20 that may be caused by fixture operations, thus effectively improving the reliability of the integrated busbar assembly 1.

[0043] Furthermore, the integrated busbar 10 also includes a mounting bracket 11, a connecting strip 12, a flexible flat cable 13, a printed circuit board 14, and a connector 15. The connecting strip 12 is fixedly installed on one side of the mounting bracket 11 to realize electrical connection between multiple battery cells. The flexible flat cable 13 is disposed on the same side of the mounting bracket 11 as the connecting strip 12. One end of the flexible flat cable 13 is electrically connected to the connecting strip 12, and the other end of the flexible flat cable 13 is electrically connected to the printed circuit board 14. The flexible flat cable 13 is used to transmit the working data of the battery cells (e.g., temperature data and voltage data). The printed circuit board 14 serves as a signal processing hub, integrating signal acquisition and processing circuitry, and is fixedly installed on the connector 15. The connector 15 is disposed on the side of the mounting bracket 11 to establish a reliable electrical connection with the battery management system, thereby realizing intelligent management and monitoring of the battery module.

[0044] The mounting bracket 11 is made of materials including, but not limited to, polypropylene and glass fiber. The polypropylene substrate and 10% glass fiber are uniformly mixed and heated above their melting point until the material is in a fully molten, flowing state. This mixture is then injected into a mold containing the shape and structure of the mounting bracket 11. After the mold cools, the molten material solidifies within the mold, forming the final mounting bracket 11. It is understood that adding 10% glass fiber to polypropylene can significantly improve the material's rigidity, tensile strength, and dimensional stability, reducing deformation caused by long-term stress or temperature changes. Furthermore, glass fiber can effectively improve the material's fatigue resistance, further enhancing the strength of the mounting bracket 11.

[0045] Specifically, the pressure strip 20 is fixedly installed on the side of the mounting bracket 11 near the battery cell, so that the pressure strip 20 can directly apply stable mechanical constraints to the battery cell assembly, improving the installation stability of the battery pack; the connecting strip 12 is fixedly installed on the other side of the mounting bracket 11 away from the battery cell, realizing the electrical connection between multiple battery cells; at the same time, the flexible flat cable 13 is arranged on the same side of the mounting bracket 11 as the connecting strip 12, and the flexible flat cable 13 is isolated from the pressure strip 20 through the mounting bracket 11, thereby improving the stability of signal transmission.

[0046] In one embodiment, the connection bus 12 includes a plurality of connection unit groups 121, each of the connection unit groups 121 including a plurality of connection units 121A; the integrated bus assembly 1 is used to connect a plurality of battery cell groups, and a plurality of battery cells of each battery cell group are electrically connected to a plurality of connection units 121A of the corresponding connection unit group 121.

[0047] Furthermore, multiple battery cell groups can be spaced apart along a first direction X; in any battery cell group, multiple battery cells can be spaced apart along a second direction Y; wherein, one connection unit group 121 corresponds to one battery cell group, and in the connection unit group 121 and its corresponding battery cell group, one connection unit 121A is used to connect two adjacent battery cells, thereby connecting multiple battery cells in series and / or in parallel; wherein, the material of the connection unit 121A includes, but is not limited to, 1060 aluminum, which is a high-purity aluminum with good conductivity, ductility and plasticity, and is easy to process into complex-shaped connection bars 12, adapting to high-precision processing requirements.

[0048] Specifically, the pressure strip 20 is located between two adjacent connecting unit groups 121, thereby installing the pressure strip 20 and the connecting unit group 121 on opposite sides of the mounting bracket 11 to form a spatially isolated layout. This avoids physical interference between the connecting busbar 12 and the pressure strip 20 during assembly or use, ensuring independent operating space for each component. At the same time, this allows the pressure strip 20 to focus on providing stable mechanical fixing functions, while the connecting busbar 12 can improve electrical connection performance. The non-interference operation of the two not only improves assembly efficiency but also enhances the working reliability of the integrated busbar assembly 1.

[0049] It should be noted that, in Figure 2In the diagram, the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction; wherein, the first direction X, the second direction Y, and the third direction Z are all perpendicular to each other, the first direction X can be the width direction of the integrated busbar 10, the second direction Y can be the length direction of the integrated busbar 10, and the third direction Z can be the height direction of the integrated busbar 10.

[0050] In one embodiment, the mounting bracket 11 has a limiting groove 111 located on the side of the mounting bracket 11 closer to the battery cell. The limiting groove 111 is used to guide and constrain the installation position of the pressure strip 20. The pressure strip 20 is embedded in the limiting groove 111, thereby forming a stable mechanical connection between the pressure strip 20 and the mounting bracket 11. At the same time, it achieves precise positioning of the pressure strip 20, improving the structural compactness and assembly convenience of the integrated busbar assembly 1.

[0051] Specifically, the limiting groove 111 extends along the second direction Y, and the pressure strip 20 can automatically align along the geometric contour of the limiting groove 111 during assembly, thereby achieving a high-precision, low-tolerance assembly effect. By placing the limiting groove 111 on the side of the mounting bracket 11 close to the battery cell, and embedding the pressure strip 20 within the limiting groove 111, the pressure strip 20 can apply a uniform constraint force to the battery cell, preventing structural loosening or poor contact due to uneven clamping. Furthermore, the setting of the limiting groove 111 allows the pressure strip 20 to be directly positioned based on the mounting bracket 11 body, without the need for external special positioning fixtures (such as auxiliary jigs or guide molds) required in related technologies, thereby simplifying the assembly process of the pressure strip 20 and reducing process complexity and assembly costs.

[0052] Meanwhile, by limiting the pressure strip 20 through the limiting groove 111, the risk of positional displacement of the pressure strip 20 during assembly can be avoided. In actual operation, the limiting groove 111 can form a reliable physical constraint on the pressure strip 20, preventing the pressure strip 20 from loosening or shifting under complex working conditions such as vibration and impact, thereby improving the stability and operational reliability of the integrated busbar assembly 1.

[0053] In one embodiment, the mounting bracket 11 includes at least one limiting portion 112, and the limiting portion 112 includes at least one limiting sub-component 1121; wherein, the limiting sub-component 1121 is disposed on the inner wall of the limiting groove 111 to abut the pressure strip 20 against the limiting groove 111, and through the contact and cooperation between the limiting sub-component 1121 and the pressure strip 20, the pressure strip 20 is effectively limited in the first direction X and the second direction Y.

[0054] One side of the pressure strip 20 abuts against the inner wall of the limiting groove 111, while the other side of the pressure strip 20 is held and positioned by the limiting sub-component 1121, thereby forming an effective constraint in the third direction Z. This can prevent the pressure strip 20 from loosening or shifting during transportation, vibration, or installation, improve the assembly accuracy and stability between the pressure strip 20 and the mounting bracket 11, and enhance the strength and impact resistance of the integrated busbar assembly 1.

[0055] Specifically, the limiting part 112 includes two limiting sub-components 1121, which are arranged opposite to each other along the first direction X, thereby achieving bidirectional limiting constraint on the pressure strip 20. Each limiting sub-component 1121 includes a first sub-component 1121A and a second sub-component 1121B. The first sub-component 1121A is fixedly installed at the bottom of the limiting groove 111, and abuts against the side of the pressure strip 20 near the bottom of the groove, effectively supporting the pressure strip 20 in the third direction Z. The second sub-component 1121B is fixedly installed on the inner wall of the limiting groove 111, and abuts against the side of the pressure strip 20 near the inner wall, thereby limiting the displacement of the pressure strip 20 in the first direction X.

[0056] The limiting part 112 and the pressure strip 20 are interlocked. The first sub-part 1121A is disposed between the pressure strip 20 and the bottom of the limiting groove 111. The first sub-part 1121A and the side of the pressure strip 20 near the bottom of the groove form a surface contact or line contact, thereby providing effective support and limiting for the pressure strip 20 in the third direction Z, preventing the pressure strip 20 from shifting downward or sinking during assembly or operation. The second sub-part 1121B is disposed between the pressure strip 20 and the inner wall of the limiting groove 111. The second sub-part 1121B and the side of the pressure strip 20 near the bottom of the groove form a surface contact or line contact, thereby providing limiting constraint for the pressure strip 20 in the second direction Y, preventing the pressure strip 20 from lateral shaking or shifting. At the same time, the interlocking connection simplifies the installation process of the limiting part 112 and the pressure strip 20, reduces assembly steps and errors, and improves assembly efficiency.

[0057] It is understood that this embodiment achieves multi-point and multi-directional stable constraint on the pressure strip 20 by setting the two limiting sub-components 1121 relative to each other along the first direction X, so that the position of the pressure strip 20 is precisely controllable during the assembly process, preventing the pressure strip 20 from shifting or loosening due to assembly errors or external force interference, and further improving the reliability and service life of the integrated busbar assembly 1.

[0058] In one embodiment, the limiting sub-component 1121 is close to the outer contour of the pressure strip 20, and matches the outer contour of the pressure strip 20 close to the limiting sub-component 1121, thereby achieving precise fitting and stable positioning. The first sub-component 1121A extends parallel to the extension direction of the bottom of the limiting groove 111, and the second sub-component 1121B extends parallel to the extension direction of the inner wall of the limiting groove 111. The outer contour of the connection between the first sub-component 1121A and the second sub-component 1121B is arc-shaped. This arc-shaped transition section achieves a smooth connection between the first sub-component 1121A and the second sub-component 1121B, avoiding stress concentration caused by structural abrupt changes at the connection point. Simultaneously, during the assembly of the pressure strip 20, the arc-shaped transition section provides a smoother guiding effect, reducing the risk of jamming and improving the assembly efficiency and reliability of the pressure strip 20.

[0059] Furthermore, the outer contour of the limiting sub-component 1121 at the connection between the first sub-component 1121A and the second sub-component 1121B is arc-shaped, and the outer contour of the pressure strip 20 near the limiting sub-component 1121 is also arc-shaped. Moreover, the arc-shaped outer contour of the limiting sub-component 1121 and the arc-shaped outer contour of the pressure strip 20 are consistent in terms of radius of curvature and arc. It can be understood that the arc-shaped outer contour design enables the pressure strip 20 to be evenly distributed along a relatively smooth curve when subjected to external force. Compared with straight lines or sharp angle designs, the arc-shaped structure can effectively withstand external impacts and pressures, thereby improving the strength and impact resistance of the pressure strip 20 and reducing the risk of breakage or deformation of the pressure strip 20 due to excessive local stress.

[0060] Specifically, along the second direction Y, the length of the limiting sub-component 1121 is greater than or equal to 164 mm and less than or equal to 243 mm. By controlling the length of the limiting sub-component 1121, the limiting sub-component 1121 forms a sufficient contact area with the pressure strip 20 in the third direction Z, thereby suppressing the displacement or warping deformation of the pressure strip 20 along the third direction Z during assembly and operation, and improving the limiting effect and stability of the limiting sub-component 1121; at the same time, it avoids affecting the layout and installation of other components due to the excessive length of the limiting sub-component 1121, and improves the coordination of the integrated busbar assembly 1 in terms of spatial layout and functional realization.

[0061] In one embodiment, the mounting bracket 11 further has at least one opening 113; wherein the opening 113 exposes at least a portion of the pressure strip 20, so that the pressure strip 20 can be directly identified or contacted from the outside of the integrated busbar assembly 1 after installation, facilitating subsequent quality inspection, maintenance operations, or electrical performance verification; at the same time, the opening 113 can also serve as a process window, allowing position calibration, fixture-assisted positioning, or the intervention of automated assembly probes during the assembly or crimping of the pressure strip 20, thereby improving assembly efficiency and consistency.

[0062] Furthermore, the mounting bracket 11 has multiple mounting slot groups 114, each mounting slot group 114 including multiple mounting slots 114A. The multiple mounting slots 114A of the mounting slot group 114 are used to install the multiple connecting units 121A of the corresponding connecting unit group 121. One mounting slot 114A corresponds to one connecting unit 121A, so as to realize the partition positioning and independent fixation of multiple connecting units 121A. The opening 113 communicates with the corresponding mounting slot 114A, so that the adhesive can be directly seen through the opening 113 to see whether the adhesive overflows evenly at the edge of the pressure strip 20, to judge whether the amount of adhesive applied and the pressing pressure are reasonable, and to avoid excessive or insufficient application. At the same time, the opening 113 can also detect problems such as positional deviation, skewing or warping of the pressure strip 20 in advance, thereby improving the yield and consistency of the integrated busbar assembly 1.

[0063] Specifically, the openings 113 and the limiting parts 112 are spaced apart, and the plurality of openings 113 correspond to different mounting grooves 114A. The length of the openings 113 is greater than or equal to 82.4 mm and less than or equal to 93 mm, and the width of the openings 113 is greater than or equal to 82.4 mm and less than or equal to 93 mm. This allows the openings 113 to fully expose the pressure strip 20, facilitating real-time observation of the glue overflow and assembly status during the pressure holding and glue application process of the pressure strip 20. It also avoids the openings 113 being too large, which could reduce the structural strength of the mounting bracket 11 or restrict the layout of other components. This improves the controllability of the assembly process of the pressure strip 20 and the overall stability of the product, reduces quality problems caused by uneven glue application or misalignment of the pressure strip 20, and enhances the assembly reliability and durability of the integrated busbar assembly 1.

The battery cell assembly is disposed within the receiving cavity. The integrated busbar assembly is disposed within the receiving cavity and is located on top of the battery cell assembly. The integrated busbar assembly is directly connected to the electrode posts of the multiple battery cells.
