Description

Technical Field

[0001] This application relates to the field of battery system technology, and more specifically, to a battery pack and a vehicle having the same. Background Technology

[0002] With the booming development of new energy vehicles in recent years, the requirements for energy density of battery packs are increasing, and the requirements for space utilization of battery packs are also gradually increasing. High-voltage lines inside battery packs are gradually being replaced by high-voltage busbars.

[0003] In existing technologies, high-voltage busbars are typically made of soft copper, aluminum, or hard copper, which are relatively soft materials with relatively small cross-sectional areas. This often leads to the high-voltage busbars rotating with the bolts during installation, causing deformation, damage to other mating structural components, reduced battery pack lifespan, and increased battery pack failure rate. Therefore, solving the problem of copper busbars rotating with bolts is urgently needed to improve battery pack yield.

[0004] There is currently no good solution to the above problems. Summary of the Invention

[0005] This application provides a battery pack and a vehicle having the same, to at least solve the technical problem of rotation during the installation of high-voltage busbars in the prior art.

[0006] According to one aspect of the embodiments of this application, a battery pack is provided, including: a cell module, a high-voltage busbar assembly, and a limiting assembly. An electrical connector is provided on one side of the cell module, and the electrical connector is connected to the cell module. The high-voltage busbar assembly includes at least a busbar body and a wiring port. The busbar body is connected to the wiring port, and the busbar body is fitted to the surface of the electrical connector. The busbar body is connected to at least one of the electrical connector and an external wiring harness through the wiring port. The limiting assembly is connected to at least one of the electrical connector and the high-voltage busbar assembly. The electrical connector is connected to the high-voltage busbar assembly through the limiting assembly to keep the electrical connector and the high-voltage busbar assembly relatively stationary.

[0007] Furthermore, the limiting component includes a limiting structure and a mating structure. The limiting structure is connected to any one of the electrical connectors and the high-voltage busbar assembly, and the mating structure is connected to the other of the electrical connectors and the high-voltage busbar assembly. The limiting structure and the mating structure are mated together so that the electrical connectors and the high-voltage busbar assembly remain relatively stationary.

[0008] Furthermore, the limiting structure is either a limiting protrusion or a limiting groove, and the mating structure is the other of a limiting protrusion or a limiting groove. When the electrical connector is mated with the high-voltage busbar assembly, at least part of the limiting protrusion extends into the limiting groove.

[0009] Furthermore, the busbar body includes: a main body section, which is fitted to the electrical connector; and a bent section, one end of which is connected to the main body section and the other end of which is connected to the wiring port; wherein the extension direction of the bent section is set at an angle to the extension direction of the main body section.

[0010] Furthermore, an insulating layer is provided on the outer surface of the main body of the busbar.

[0011] Furthermore, the electrical connector includes a mounting base, which is connected to the battery cell module, and the mounting base has at least one connection hole.

[0012] Furthermore, at least one mating hole is provided on the wiring port, and the mating hole is set in correspondence with the connection hole. The bolt passes through the mating hole and the connection hole to connect the mating hole and the connection hole.

[0013] Furthermore, the mounting base is made of plastic.

[0014] Furthermore, the electrical connector also includes a busbar connection base, one side of which is connected to the mounting base, and the other side of which is connected to the busbar body. The busbar connection base has through holes, which are correspondingly set with connection holes and mating holes.

[0015] According to another aspect of the embodiments of this application, a vehicle is also provided, the vehicle having a battery pack, the battery pack being the battery pack described in the above embodiments.

[0016] In this embodiment, the cooperation between the limiting component and the electrical connector and the high-voltage busbar assembly ensures that the electrical connector and the high-voltage busbar assembly remain relatively stationary. An electrical connector is provided on one side of the cell module, directly connected to the cell module, facilitating electrical connection between the cell module, the high-voltage busbar assembly, and external wiring harnesses. The surface of the busbar body is tightly fitted with the electrical connector, achieving electrical connection through the wiring port, ensuring smooth current flow from the cell module to other components in the system. The limiting component guarantees stability and safety between the electrical connector and the high-voltage busbar assembly. By connecting to at least one component of the electrical connector and the high-voltage busbar assembly, a mechanical locking mechanism is formed, preventing the high-voltage busbar assembly from moving relative to the electrical connector during installation. This also prevents loosening of the connection due to vibration or external force after installation, improving the reliability and yield of the entire battery pack and extending its service life.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] like Figures 1 to 3 As shown, according to an embodiment of this application, a battery pack is provided.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, the battery pack includes a cell module 10, a high-voltage busbar assembly 30, and a limiting assembly 40. An electrical connector 20 is provided on one side of the cell module 10, and the electrical connector 20 is connected to the cell module 10. The high-voltage busbar assembly 30 includes at least a busbar body 31 and a wiring port 32. The busbar body 31 is connected to the wiring port 32. The busbar body 31 is attached to the surface of the electrical connector 20. The busbar body 31 is connected to at least one of the electrical connector 20 and an external wiring harness through the wiring port 32. The limiting assembly 40 is connected to at least one of the electrical connector 20 and the high-voltage busbar assembly 30. The electrical connector 20 is connected to the high-voltage busbar assembly 30 through the limiting assembly 40 so that the electrical connector 20 and the high-voltage busbar assembly 30 remain relatively stationary.

[0030] By applying the technical solution of this embodiment, the cooperation between the limiting component 40, the electrical connector 20, and the high-voltage busbar assembly 30 ensures that the electrical connector 20 and the high-voltage busbar assembly 30 remain relatively stationary. An electrical connector 20 is provided on one side of the battery cell module 10, and the electrical connector 20 is directly connected to the battery cell module 10, facilitating electrical connections between the battery cell module 10, the high-voltage busbar assembly 30, and external wiring harnesses. The surface of the busbar body 31 is tightly fitted with the electrical connector 20, and electrical connection is achieved through the wiring port 32, ensuring that current can flow smoothly from the battery cell module 10 to other components in the system. The limiting component 40 ensures the stability and safety between the electrical connector 20 and the high-voltage busbar assembly 30. By connecting with at least one component of the electrical connector 20 and the high-voltage busbar assembly 30, a mechanical locking mechanism is formed, which prevents the high-voltage busbar assembly 30 from moving relative to the electrical connector 20 during installation. It also prevents the connection of the high-voltage busbar assembly 30 from loosening due to vibration or external force after installation, thereby improving the reliability and yield of the entire battery pack and extending its service life.

[0031] Specifically, such as Figure 1 and Figure 2As shown, the limiting component 40 includes a limiting structure 41 and a mating structure 42. The limiting structure 41 is connected to either the electrical connector 20 or the high-voltage busbar assembly 30, and the mating structure 42 is connected to the other of the electrical connector 20 and the high-voltage busbar assembly 30. The limiting structure 41 and the mating structure 42 are mated together to keep the electrical connector 20 and the high-voltage busbar assembly 30 relatively stationary. The limiting structure 41 can be directly connected to either the electrical connector 20 or the high-voltage busbar assembly 30, providing a fixed anchor point, while the mating structure 42 is connected to the other of the electrical connector 20 or the high-voltage busbar assembly 30, forming a dynamic mating point. When the limiting structure 41 and the mating structure 42 are accurately aligned, their interaction ensures a stable connection between the electrical connector 20 and the high-voltage busbar assembly 30. This achieves relative stillness between the electrical connector 20 and the high-voltage busbar assembly 30, ensuring that the connection between the electrical connector 20 and the high-voltage busbar assembly 30 will not shift under any external force in any direction, thereby improving the reliability and durability of the electrical connection inside the battery pack.

[0032] In one exemplary embodiment of this application, the limiting structure 41 is either a limiting protrusion or a limiting groove, and the mating structure 42 is the other of the limiting protrusion and limiting groove. When the electrical connector 20 is mated with the high-voltage busbar assembly 30, at least a portion of the limiting protrusion extends into the limiting groove. When the electrical connector 20 and the high-voltage busbar assembly 30 are mated, the limiting protrusion on one component is precisely inserted into the limiting groove on the other component, achieving mechanical interlocking. The embedded connection between the limiting protrusion and the limiting groove effectively constrains the relative movement between the electrical connector 20 and the high-voltage busbar assembly 30, especially in the X and Y directions, preventing rotation or sliding that may occur during installation or vehicle operation.

[0033] It should be noted that the X direction refers to the length direction of the high-voltage busbar assembly 30 and the electrical connector 20 within the battery pack mounting plane, i.e., the horizontal direction; the Y direction refers to the width direction of the high-voltage busbar assembly 30 and the electrical connector 20 within the battery pack mounting plane, i.e., the longitudinal direction.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, the busbar body 31 includes a main body section 311 and a bent section 312. The main body section 311 is fitted with the electrical connector 20. One end of the bent section 312 is connected to the main body section 311, and the other end of the bent section 312 is connected to the wiring port 32. The extension direction of the bent section 312 is set at an angle to the extension direction of the main body section 311.

[0035] In this embodiment, the bent section 312 is located at one end of the main body section 311 and connected to the wiring port 32. The bent section 312 is angled relative to the main body section 311, optimizing the space occupied by the high-voltage busbar assembly 30 within the battery pack. This facilitates effective layout and coordination with other components such as the limiting assembly 40, and also helps improve the overall space utilization of the battery pack. Furthermore, the bending shape of the bent section 312 can enhance the rigidity of the busbar body 31 to a certain extent, reducing the risk of deformation caused by external forces (such as vibration), and ensuring the reliability and durability of the high-voltage busbar assembly 30 in complex working environments. The connection method between the bent section 312 and the wiring port 32 can also optimize the current flow path and reduce heat accumulation, thereby comprehensively improving the performance of the battery pack.

[0036] Specifically, an insulating layer is provided on the outer surface of the busbar body 31. This insulating layer effectively isolates the busbar body 31 from direct contact with other metal structural components inside the battery pack, preventing short-circuit accidents. In high-voltage environments, it reduces electrical safety hazards caused by accidental contact, protects the battery pack from current leakage, and ensures operator safety. Furthermore, the insulating layer helps reduce electromagnetic interference (EMI). In densely packed electrical components, the insulating layer can act as part of the shielding material, preventing the magnetic field generated by the current from interfering with adjacent electrical circuits, ensuring clear and stable signal transmission within the battery pack.

[0037] In one embodiment of this application, the insulating layer uses a material with good abrasion resistance and heat resistance to adapt to the harsh operating conditions inside the battery pack. In practical applications, common insulating materials include polyimide film (PI), heat shrink tubing, and polyvinyl chloride (PVC) insulating sleeves. These materials can not only withstand high-voltage currents but also resist the effects of harsh environments, extending the service life of the busbar body 31 and its connection points.

[0038] Furthermore, the electrical connector 20 includes a mounting base 21, which is connected to the battery cell module 10, and the mounting base 21 has at least one connection hole 210.

[0039] In this embodiment, the mounting base 21 securely connects the electrical connector 20 to the battery cell module 10, ensuring the stability and reliability of the electrical connection. The connection hole 210 provides access points for mounting bolts or other fasteners, enabling the electrical connector 20 to accurately mate with the wiring port 32 of the high-voltage busbar assembly 30 via these fasteners.

[0040] In one embodiment of this application, the number and position of the connection holes 210 can be adjusted according to the actual situation. For example, a multi-hole design can provide a more balanced fixing force and enhance the stability of the connection. The position of the connection holes 210 should take into account the precise alignment of the limiting structure 41 and the mating structure 42 of the high-voltage busbar assembly 30, so as to ensure that the limiting structure can smoothly engage with the mating structure during installation, thereby achieving relative stillness between the electrical connector 20 and the high-voltage busbar assembly 30.

[0041] In one embodiment of this application, the mounting base 21 may also include other structural features, such as reinforcing ribs or concave-convex structures, to enhance its mechanical strength and reduce deformation or damage caused by external forces during installation or vehicle operation.

[0042] Furthermore, at least one mating hole 320 is provided on the wiring port 32, and the mating hole 320 is correspondingly provided with the connecting hole 210. The bolt passes through the mating hole 320 and the connecting hole 210 to connect the mating hole 320 and the connecting hole 210.

[0043] In this embodiment, the position of the mating hole 320 corresponds to the connection hole 210 on the mounting base 21, ensuring precise alignment and mating between the two components. When the high-voltage busbar assembly 30 and the electrical connector 20 are assembled, the bolt passes through the mating hole 320 on the wiring port 32 and is then aligned with the connection hole 210 on the mounting base 21. By tightening the bolt, the high-voltage busbar assembly 30 and the electrical connector 20 are securely fixed. The bolt not only provides sufficient mechanical strength to ensure a stable connection, but also establishes a current path between the electrical connector 20 and the high-voltage busbar assembly 30 through its conductivity, ensuring that current can flow smoothly from the cell module 10 to the high-voltage busbar assembly 30, thereby achieving electrical connection within the entire battery pack.

[0044] In one embodiment of this application, the mounting base 21 is made of plastic. Plastic is lightweight, effectively reducing the overall weight of the structure. It also possesses excellent insulation properties, ensuring the safety of the high-voltage busbar during operation. Furthermore, plastic is cost-effective and easy to process and mold, facilitating mass production.

[0045] Furthermore, the electrical connector 20 also includes a busbar connection base 22. One side of the busbar connection base 22 is connected to the mounting base 21, and the other side of the busbar connection base 22 is connected to the busbar body 31. The busbar connection base 22 has a through hole, which is correspondingly set with the connection hole 210 and the mating hole 320.

[0046] In this embodiment, the busbar connection base 22 enhances the connection stability between the busbar body 31 and the mounting base 21, while optimizing the performance of the electrical connection. When the electrical connector 20 is connected to the high-voltage busbar assembly 30, the bolts pass through the through hole of the busbar connection base 22, the connection hole 210 of the mounting base 21, and the mating hole 320 of the wiring port 32 in sequence, finally fixing all parts tightly together. This triple connection structure not only improves the mechanical stability of the connection but also ensures electrical continuity, realizing efficient current transmission between the battery cell module 10 and the high-voltage busbar assembly 30.

[0047] According to another aspect of this application, a vehicle is also provided, the vehicle having a battery pack, the battery pack being the battery pack described in the above embodiments. Applying the battery pack from the above embodiments to a vehicle achieves precise alignment and fixation between the high-voltage busbar assembly 30 and the electrical connector 20. The addition of the limiting component 40 effectively restricts the rotation of the high-voltage busbar assembly 30 in the X and Y directions, preventing structural deformation that may occur during installation due to bolt rotation, reducing the risk of bolt loosening, and thus improving the stability and reliability of the electrical connection.

[0048] According to another aspect of this application, a preferred embodiment of a battery pack is also provided. The battery pack includes an anti-rotation structure, which is a high-voltage busbar assembly 30. The high-voltage busbar assembly 30 includes: a T-shaped downward limiting protrusion at the connection port of the high-voltage busbar assembly 30, and a limiting groove below the electrical connection structure connected to the high-voltage busbar assembly 30 at the lower part, so that the high-voltage busbar assembly 30 cooperates with the electrical connector 20 to limit the high-voltage busbar assembly 30.

[0049] On the third axis, i.e. Z-axis, perpendicular to the plane of the battery pack, a mating structure 42 is set in the Z-axis. This mating structure 42 extends 2mm in the Z-axis. Then, a limiting structure 41 is set on the electrical connection busbar that mates with the high-voltage busbar assembly 30. During installation, the limiting protrusion of the high-voltage busbar assembly 30 mates with the limiting groove. Electrical connection uses electrical connector 20 to fix the two high-voltage busbar assemblies 30 together.

[0050] The matching of the limiting groove and the high-voltage busbar assembly 30 limits the high-voltage busbar assembly 30 in the X and Y directions to prevent the high-voltage busbar assembly 30 from rotating along the electrical connector 20. This prevents the high-voltage busbar assembly 30 from deforming, which would cause a decrease in electrical performance and structural strength. On the other hand, it also prevents the high-voltage busbar assembly 30 from deforming and the insulation layer from contacting the outer surface of the busbar body 31, thus avoiding insulation failure of the battery pack. The matching of the limiting groove and the high-voltage busbar assembly 30 also limits the amplitude of busbar swaying with vibration, reducing the risk of bolt loosening.

[0051] As can be seen from the above description, the battery pack in the above embodiments has the following beneficial effects:

[0052] (1) Improve anti-rotation capability and structural stability: By designing a limiting protrusion on the wiring port 32 of the high voltage busbar assembly 30 and opening a corresponding limiting groove on the electrical connector 20, the rotation of the high voltage busbar assembly 30 in the X and Y directions is effectively restricted, avoiding the problems of reduced electrical performance and reduced structural strength caused by the rotation of the high voltage busbar assembly 30.

[0053] (2) Optimize space utilization and assembly safety: Compared with traditional tooling or base limiting methods, this embodiment uses the anti-rotation structure of the high voltage busbar assembly 30 itself to achieve limiting, which reduces the use of tooling, eliminates the risk of tooling left in the product, and does not occupy additional installation base space, thus optimizing the internal space layout of the battery pack and improving the overall assembly safety and space utilization.

[0054] (3) Enhance the stability of the connection between the electrical connector 20 and the high voltage busbar assembly 30: The busbar connection base 22 is introduced, and its through hole is precisely aligned with the connection hole of the mounting base 21 and the mating hole of the wiring port 32. The connection is formed by bolts to form a stable triple fixing structure, which not only enhances the stability of the electrical connection, but also disperses the stress at the connection point and reduces the possibility of component damage.

[0055] (4) Improve current path and optimize thermal management: The connection method between the bent section 312 of the busbar body 31 and the wiring port 32, as well as the shape design of the busbar connection base 22, are conducive to the uniform distribution of current, reduce local overheating, optimize the thermal management efficiency of the entire battery pack, and improve electrical safety and system life.

[0056] (5) Improve electrical safety: The insulation layer set on the outer surface of the busbar body 31 effectively isolates the high voltage busbar from other metal structural components in the battery pack, avoids the risk of short circuit, and reduces electromagnetic interference, ensuring a safe electrical connection between the cell module and the high voltage busbar.

[0057] (6) Design flexibility and scalability: The anti-rotation structure design in this application allows for flexible adjustment of the size and position of the limiting protrusion according to different types of high voltage busbar assemblies 30. This not only meets the requirements for installation error prevention, but also provides design flexibility and scalability for future product upgrades or adaptation to different vehicle models.
