Description

Technical Field

[0001] This application relates to the field of power battery assembly technology, specifically to a battery pack and a vehicle. Background Technology

[0002] In the field of automotive battery pack manufacturing, a good equipotential connection between the battery pack housing and the internal cold plate can effectively avoid electrochemical corrosion caused by potential difference, prevent leakage caused by corrosion perforation of the cooling system, and also optimize the electromagnetic compatibility performance of the battery pack to ensure the stable operation of the electrical system.

[0003] Currently, the industry commonly uses additional structural components to achieve equipotential bonding between the cold plate and the enclosure. Common implementation methods include welding a dedicated metal bracket between the enclosure and the cold plate, or placing conductive foam or metal spring clips in the assembly gap between the two.

[0004] However, both welding brackets and installing conductive cotton require space inside the battery pack. When the internal layout of the enclosure is highly integrated and space resources are scarce, it is impossible to find enough redundant space to accommodate these additional connectors, making the design impossible to implement. Secondly, adding independent connectors also increases the costs of raw materials, installation procedures, and management. Utility Model Content

[0005] In view of this, this application provides a battery pack and vehicle to solve the problem that additionally designed connectors occupy internal space of the battery pack and increase costs.

[0006] In a first aspect, this application provides a battery pack, comprising: The box body has a box beam, and a first insulating layer is provided on the outer side wall of the box beam; A cold plate is disposed on one side of the housing, and a second insulating layer is disposed on the outer side wall of the cold plate, wherein the first insulating layer and the second insulating layer abut against each other; The first insulating layer has a first blank area, and the second insulating layer has a second blank area. The first blank area and the second blank area are provided correspondingly. A conductive layer is provided in the first blank area and / or the second blank area, and the conductive layer abuts against the box girder and the cold plate, respectively.

[0007] Beneficial Effects: By setting a first insulating layer and a second insulating layer on the box beam and cold plate of the battery pack respectively, and correspondingly setting a first blank area and a second blank area, and then setting a conductive layer in the blank area, the box beam and cold plate can be directly connected at the same potential through the conductive layer. This avoids the need for additional structural components such as welded brackets or springs required in traditional methods, thus significantly saving internal space of the battery pack and making it suitable for space-constrained designs. At the same time, since no additional parts are needed, material costs and installation complexity are reduced, improving production efficiency and economy. Furthermore, the conductive layer is in direct contact with the substrate of the box beam and cold plate, ensuring the reliability and stability of the electrical connection, effectively preventing electrochemical corrosion caused by potential differences, extending the battery pack's lifespan, and optimizing electromagnetic compatibility performance.

[0008] In one optional embodiment, the box girder is provided with a first mounting hole, and the cold plate is provided with a second mounting hole. The first mounting hole is located on the side of the box girder facing the cold plate, and the second mounting hole is located on the side of the cold plate facing the box girder. The box girder and the cold plate are connected by connectors inserted into the first and second mounting holes.

[0009] Beneficial effects: By setting mounting holes in the box girder and cold-rolled plate and connecting them with connectors, not only is mechanical fixing achieved, but the layout of the equipotential bonding is also optimized through the position of the mounting holes. The blank area is located at the edge of the mounting holes, allowing the conductive layer to fit tightly near the connection point, enhancing the reliability and conductivity of the electrical connection. At the same time, the combination of mechanical and electrical connections simplifies the assembly process, reduces the number of parts, lowers the overall cost, and improves the structural stability and maintenance convenience of the battery pack.

[0010] In one alternative embodiment, the first blank area is located at the edge of the opening of the first mounting hole, and the second blank area is located at the edge of the opening of the second mounting hole.

[0011] Beneficial effects: The blank area is specifically defined at the edge of the mounting hole, allowing the conductive layer to directly cover areas of stress concentration, thus improving the stability of the equipotential bonding. This layout ensures effective contact of the conductive layer at mechanical connection points, avoiding connection failures caused by insulation residue, and further enhancing the stability and durability of the connection.

[0012] In one alternative embodiment, the first blank area extends circumferentially along the first mounting hole and is configured as an annular structure, and the second blank area extends circumferentially along the second mounting hole and is configured as an annular structure.

[0013] Beneficial effects: By setting the blank area as a ring structure and extending it circumferentially along the mounting hole, a uniform conductive ring is formed, ensuring 360-degree electrical contact between the box girder and the cold plate, and improving the uniformity and reliability of the equipotential bonding. This ring design reduces the risk of excessive local resistance, optimizes current distribution, enhances resistance to corrosion and electromagnetic interference, and, due to its symmetrical structure, facilitates manufacturing and assembly, improving production consistency and quality control.

[0014] In one alternative embodiment, the connector includes: The connecting part and the abutting part are connected. The connecting part passes through the second mounting hole and the first mounting hole in sequence and is connected to the box girder. The abutting part abuts against the side of the cold plate away from the box girder. The connecting part passes through the conductive layer.

[0015] Beneficial effects: By further defining the structure of the connector, the robustness of the mechanical connection and the continuity of the electrical connection are ensured. While providing a fastening function, the connector does not interfere with the performance of the conductive layer; instead, its through-hole design enhances the contact pressure between the conductive layer and the substrate, improving connection reliability. Furthermore, this structure simplifies installation, reduces potential points of failure, and lowers maintenance requirements.

[0016] In one alternative implementation, it further includes: A gasket, configured as a ring structure, is fitted onto the outside of the connecting part, and the gasket is located between the abutting part and the cold plate.

[0017] Beneficial effects: The gaskets disperse connection pressure, prevent damage to the cold plate surface, and improve the sealing and anti-loosening ability of the connection. The use of gaskets optimizes the distribution of mechanical stress, extends the service life of the connectors, and ensures the stability of the conductive layer during long-term operation, further enhancing the safety and reliability of the battery pack.

[0018] In one optional implementation, multiple first blank areas and multiple second blank areas are provided, and the multiple first blank areas and multiple second blank areas are respectively provided in a one-to-one correspondence.

[0019] Beneficial effects: By setting multiple blank areas and corresponding them one-to-one, multiple equipotential bonding points are achieved, providing redundant design and enhancing the system's reliability and fault tolerance. Multiple bonding points distribute the current load, reducing the risk of single-point failure and ensuring that even if individual bonding points fail, the overall equipotential performance remains maintained, thereby improving the battery pack's adaptability to harsh environments and long-term operational stability.

[0020] In one optional embodiment, multiple first mounting holes and multiple second mounting holes are provided, and the multiple first mounting holes and multiple second mounting holes are respectively provided in a one-to-one correspondence. Each pair of first mounting holes and second mounting holes forms a mounting hole group, and the conductive layer is provided at the edge position of at least one of the mounting hole groups.

[0021] Beneficial effects: By defining multiple mounting hole groups and placing a conductive layer at the edge of at least one mounting hole group, this provides design flexibility, allowing the selection of optimal connection points based on actual space and performance requirements. This configuration ensures at least one reliable equipotential connection path, while optimizing current distribution and structural strength through multi-point layout, reducing overall resistance, improving battery pack efficiency and safety, and adapting to diverse design needs.

[0022] In one alternative embodiment, the conductive layer is a conductive paint layer.

[0023] Beneficial effects: By using a conductive paint layer as the conductive layer, the advantages of conductive paint—low ​​cost, easy application, and strong adhesion—are utilized, further reducing material and production costs. Conductive paint is easy to spray and cure, accurately covering blank areas and providing uniform conductivity. Compared to other metal connection methods, it requires no complex processing, reducing production time and technical barriers, while maintaining good electrical and corrosion resistance.

[0024] Secondly, this application also provides a vehicle, including a battery pack.

[0025] Since the vehicle includes a battery pack, which has the same effect as the battery pack, it will not be elaborated on here. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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 some embodiments of this application, not all 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.

[0030] The following is combined with Figures 1 to 8 This describes an embodiment of the present application.

[0031] According to an embodiment of this application, a battery pack is provided, including a housing 1 and a cold plate 2. The housing 1 has a box beam 101, and a first insulating layer 102 is disposed on the outer side wall of the box beam 101. The cold plate 2 is disposed on one side of the housing 1, and a second insulating layer 201 is disposed on the outer side wall of the cold plate 2, with the first insulating layer 102 and the second insulating layer 201 abutting against each other. The first insulating layer 102 has a first blank area 103, and the second insulating layer 201 has a second blank area 202, with the first blank area 103 and the second blank area 202 correspondingly disposed. A conductive layer 5 is disposed within the first blank area 103 and / or the second blank area 202, and the conductive layer 5 abuts against the box beam 101 and the cold plate 2 respectively.

[0032] It should be noted that the box body 1 is made of steel, and an electrophoretic layer needs to be applied to it to achieve corrosion resistance. The box beam 101 is an expansion beam structure on the box body 1, therefore, an electrophoretic layer is also applied to the box beam 101. This electrophoretic layer is made of insulating material, namely the first insulating layer 102. Similarly, to achieve corrosion resistance and insulation, the cold-rolled plate 2 will be coated with epoxy resin, and the sprayed epoxy resin layer is the second insulating layer 201.

[0033] Understandably, by selecting an area on the box girder 101 of the box body 1 for masking and then applying an electrophoretic coating, the substrate of the box girder 101 can be exposed in this area, which is the first blank area 103. Similarly, by selecting an area on the cold plate 2 for masking and then applying epoxy resin, the substrate of the cold plate 2 can be exposed in this area, which is the second blank area 202. The first blank area 103 and the second blank area 202 are correspondingly arranged in the direction from the cold plate 2 to the box body 1.

[0034] Optionally, the conductive layer 5 may be provided only in the first blank area 103. The thickness of the conductive layer 5 must be greater than the thickness of the first insulating layer 102, so that the conductive layer 5 protrudes from the first blank area 103 and extends into the second blank area 202, and can abut against the outer wall of the cold plate 2, thereby achieving electrical connection.

[0035] Optionally, the conductive layer 5 may be provided only in the second blank area 202. The thickness of the conductive layer 5 must be greater than the thickness of the second insulating layer 201, so that the conductive layer 5 protrudes from the second blank area 202 and extends into the first blank area 103, and can abut against the outer wall of the box girder 101, thereby achieving electrical connection.

[0036] Optionally, conductive layers 5 can be provided in the first blank area 103 and the second blank area 202 respectively, so that the two conductive layers 5 can abut against each other, thereby realizing electrical connection.

[0037] In this embodiment, by providing a first insulating layer 102 and a second insulating layer 201 on the box beam 101 and the cold plate 2 of the housing 1, respectively, and correspondingly providing a first blank area 103 and a second blank area 202, and then providing a conductive layer 5 in the blank area, the box beam 101 and the cold plate 2 can be directly connected at the same potential through the conductive layer 5. This avoids the need for additional structural components such as welding brackets or installing springs in traditional methods, thus significantly saving internal space of the battery pack and making it suitable for space-constrained design scenarios. At the same time, since no additional parts are required, material costs and installation process complexity are reduced, improving production efficiency and economy. In addition, the conductive layer 5 is in direct contact with the substrate of the box beam 101 and the cold plate 2, ensuring the reliability and stability of the electrical connection, effectively preventing electrochemical corrosion caused by potential difference, extending the service life of the battery pack, and optimizing electromagnetic compatibility performance.

[0038] In one embodiment, a first mounting hole 104 is provided on the box girder 101, and a second mounting hole 203 is provided on the cold plate 2. The first mounting hole 104 is located on the side of the box girder 101 facing the cold plate 2, and the second mounting hole 203 is located on the side of the cold plate 2 facing the box girder 101. The box girder 101 and the cold plate 2 are connected by a connector 3 inserted into the first mounting hole 104 and the second mounting hole 203.

[0039] It should be noted that the first mounting hole 104 on the box girder 101 and the second mounting hole 203 on the cold plate 2 are set accordingly. By connecting the box girder 101 and the cold plate 2 through the connector 3, the box body 1 and the cold plate 2 can be connected. In this way, the conductive layer 5 can be connected to the substrate of the box body 1 and the substrate of the cold plate 2, so as to achieve the effect of equipotential connection.

[0040] In this embodiment, by providing mounting holes on the box girder 101 and the cold plate 2, and connecting them with connectors 3, not only is mechanical fixing achieved, but the layout of the equipotential bonding is also optimized by the position of the mounting holes. The blank area is located at the edge of the mounting holes, allowing the conductive layer 5 to fit tightly near the connection point, enhancing the reliability and conductivity of the electrical connection. Simultaneously, the combination of mechanical and electrical connections simplifies the assembly process, reduces the number of parts, lowers the overall cost, and improves the structural stability and maintenance convenience of the battery pack.

[0041] In one embodiment, the first blank area 103 is located at the edge of the opening of the first mounting hole 104, and the second blank area 202 is located at the edge of the opening of the second mounting hole 203.

[0042] It should be noted that, since the connection between the housing 1 and the cold plate 2 is achieved by the connector 3 passing through the first mounting hole 104 and the second mounting hole 203, the surrounding areas of the first mounting hole 104 and the second mounting hole 203 are stress concentration areas. Therefore, the first blank area 103 and the second blank area 202 are respectively set close to the first mounting hole 104 and the second mounting hole 203, thereby ensuring the connection stability of the conductive layer 5.

[0043] Understandably, the fastening force provided by connector 3 ensures that the conductive layer 5 withstands sufficient pressure in this area, resulting in lower and more stable contact resistance. Secondly, this location is a stress concentration area; combining the conductive connection point with the mechanical connection point eliminates the need for additional space on the housing 1 or cold plate 2, making it suitable for compact battery pack designs. Finally, in the assembly process, conductive paint can be uniformly applied to the shielded area around the mounting holes before installing connector 3, allowing for seamless integration of electrical connection and mechanical assembly processes, thus improving production efficiency.

[0044] In this embodiment, the blank area is specifically defined at the edge of the mounting hole, which allows the conductive layer 5 to directly cover the area of ​​stress concentration, improving the stability of the equipotential connection. This layout ensures effective contact of the conductive layer 5 at the mechanical connection point, avoiding connection failure due to insulation layer residue, and further enhancing the stability and durability of the connection.

[0045] In one embodiment, the first blank area 103 extends circumferentially along the first mounting hole 104 and is configured as an annular structure, and the second blank area 202 extends circumferentially along the second mounting hole 203 and is configured as an annular structure.

[0046] It should be noted that the first blank area 103 and the second blank area 202 are designed to extend along the edge of the mounting hole, thus forming a ring structure, i.e., surrounding the mounting hole. Based on this, the conductive layer 5 can also be configured as a ring structure.

[0047] Understandably, the annular conductive layer 5 provides a larger effective contact area compared to point-like or small-block areas, reducing local contact resistance and the risk of overheating. This not only improves the performance of the equipotential bonding but also enhances its long-term stability under harsh conditions such as vibration and thermal shock. In manufacturing, the processing of this annular blank area can be stably achieved by designing an annular shield or patch in the electrophoresis and spraying tooling.

[0048] In this embodiment, by setting the blank area as a ring structure and extending it circumferentially along the mounting hole, a uniform conductive ring is formed, ensuring 360-degree electrical contact between the box girder 101 and the cold plate 2, and improving the uniformity and reliability of the equipotential bonding. This ring design reduces the risk of excessive local resistance, optimizes current distribution, enhances resistance to corrosion and electromagnetic interference, and, due to its symmetrical structure, facilitates manufacturing and assembly, improving production consistency and quality control.

[0049] In one embodiment, the connector 3 includes a connecting portion 301 and an abutting portion 302 connected together. The connecting portion 301 passes through the second mounting hole 203 and the first mounting hole 104 in sequence and is connected to the box girder 101. The abutting portion 302 abuts against the side of the cold plate 2 away from the box girder 101. The connecting portion 301 passes through the conductive layer 5.

[0050] It should be noted that the connecting part 301 is the threaded part of the bolt, which passes through the second mounting hole 203, the conductive layer 5 and the first mounting hole 104 on the cold plate 2 in sequence, and is locked with a nut (not shown in the figure) or a threaded hole on the box girder 101. The abutting part 302 is the head of the bolt, which, after being locked, abuts tightly against the side of the cold plate 2 away from the box body 1.

[0051] In this embodiment, by further defining the structure of connector 3, the robustness of the mechanical connection and the continuity of the electrical connection are ensured. Connector 3 provides a fastening function without interfering with the performance of the conductive layer 5; instead, its through-hole design enhances the contact pressure between the conductive layer 5 and the substrate, improving connection reliability. Furthermore, this structure simplifies installation steps, reduces potential points of failure, and lowers maintenance requirements.

[0052] In one embodiment, a gasket is also included. The gasket is configured as an annular structure and is sleeved on the outside of the connecting portion 301. The gasket is located between the abutting portion 302 and the cold plate 2.

[0053] It should be noted that the gasket can be configured as a ring structure, fitted onto the outside of the connecting part 301, and placed between the abutting part 302 (bolt head) and the cold plate 2. The gasket can disperse the pressure applied by the abutting part 302, preventing damage to the coating or substrate of the cold plate 2, and also preventing loosening of the connection, further ensuring the long-term reliability of the mechanical and electrical connections. The connecting part 301 directly penetrates the conductive layer 5, ensuring that the tightening torque is not affected by the thickness of the conductive paint during the fastening process, and that the tightening force can be directly applied to the conductive connection interface.

[0054] In this embodiment, the gasket disperses connection pressure, prevents damage to the surface of the cold plate 2, and improves the sealing and anti-loosening ability of the connection. The use of the gasket optimizes the distribution of mechanical stress, extends the service life of the connector 3, and ensures the stability of the conductive layer 5 during long-term operation, further enhancing the safety and reliability of the battery pack.

[0055] In one embodiment, multiple first blank areas 103 and multiple second blank areas 202 are provided, and the multiple first blank areas 103 and multiple second blank areas 202 are respectively provided in a one-to-one correspondence.

[0056] In this embodiment, multiple equipotential connection points are achieved by setting multiple blank areas and corresponding them one-to-one, providing redundancy and enhancing the system's reliability and fault tolerance. Multiple connection points distribute the current load, reducing the risk of single-point failure and ensuring that even if individual connection points fail, the overall equipotential performance remains maintained, thereby improving the battery pack's adaptability to harsh environments and its long-term operational stability.

[0057] In one embodiment, multiple first mounting holes 104 and multiple second mounting holes 203 are provided, and the multiple first mounting holes 104 and multiple second mounting holes 203 are respectively provided in a one-to-one correspondence. Each pair of first mounting holes 104 and second mounting holes 203 forms a mounting hole group, and a conductive layer 5 is provided at the edge of at least one mounting hole group.

[0058] In this embodiment, by defining multiple mounting hole groups and providing a conductive layer 5 at the edge of at least one mounting hole group, design flexibility is provided, allowing the selection of the optimal connection point based on actual space and performance requirements. This configuration ensures at least one reliable equipotential connection path, while optimizing current distribution and structural strength through multi-point layout, reducing overall resistance, improving battery pack efficiency and safety, and adapting to diverse design needs.

[0059] In one embodiment, the conductive layer 5 is a conductive paint layer.

[0060] It should be noted that conductive layer 5 is a conductive paint layer. Conductive paint is a coating mixed with conductive fillers such as silver, copper, nickel, or carbon. It has advantages such as low cost, easy construction (it can be applied by spraying, brushing, etc.), and strong adhesion. Compared with solutions such as welding brackets, using springs, or conductive foam, conductive paint eliminates the need to purchase and install additional metal structural components, saving material and management costs.

[0061] In this embodiment, the conductive layer 5 is set as a conductive paint layer. The advantages of conductive paint—low ​​cost, easy application, and strong adhesion—further reduce material and production costs. Conductive paint is easy to spray and cure, can accurately cover blank areas, provides uniform conductivity, and compared to other metal connection methods, requires no complex processing, reducing production time and technical barriers, while maintaining good electrical and corrosion resistance.

[0062] In one embodiment, a bottom plate 4 is also provided on the side of the cold plate 2 away from the housing 1.

[0063] According to an embodiment of this application, another aspect provides a vehicle including a battery pack.

[0064] Since the vehicle includes a battery pack, which has the same effect as the battery pack, it will not be elaborated on here.
