Description

Technical Field

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

[0002] The battery pack is a core component of new energy vehicles. It consists of multiple individual batteries arranged into modules and packaged together, along with key components such as the battery management system, and covered with a robust outer shell for protection.

[0003] The battery pack casing is the load-bearing and protective structure of the battery pack, primarily used to protect lithium batteries from damage caused by external impacts and compression. It plays a crucial role in the safe operation and protection of the battery module. It is typically made of materials such as steel plates or aluminum alloys, with a surface coating treatment. However, with the development of energy conservation, environmental protection, and lightweighting in the automotive industry, various lightweight material options have emerged for battery casings, including glass fiber reinforced composite materials, SMC sheet materials, and carbon fiber reinforced composite materials.

[0004] In related technologies, current new energy vehicles can replenish the vehicle's electrical energy through battery swapping or perform regular inspections and maintenance of the battery. However, after frequent replacement of the power battery, problems such as loosening of the battery pack mounting bolts and wear of fasteners may occur, which in turn leads to a decrease in the compatibility between the power battery and the chassis or battery compartment, making the battery pack prone to shaking.

[0040] According to a first aspect of the embodiments of this application, a battery pack is provided, which will be described below in conjunction with... Figures 1 to 8 Describe in detail the structure and working principle of the battery pack.

[0041] According to an embodiment of this application, the battery pack is used in a vehicle, and the vehicle has a mounting area for mounting the battery pack. The battery pack includes a housing, a plurality of individual battery cells, and a compensation assembly. In an embodiment, the housing includes a first wall and a second wall disposed opposite to each other in a first direction, and the housing also includes a side portion disposed between the first wall and the second wall.

[0042] In one embodiment, multiple individual battery cells are disposed within a space defined by a first wall, a second wall, and a side portion. In another embodiment, the compensation assembly includes a compensation mounting portion and a compensation support portion. The compensation mounting portion is detachably connected to the housing, and the compensation support portion is located on the side of the compensation mounting portion away from the housing. The compensation support portion can be close to or away from the housing, and is used for support within the mounting area.

[0043] Thus, according to the embodiments of this application, the battery pack with the compensation component detachably connected to the housing, when the battery pack is loose or wobbly in the installation area of ​​the vehicle, the compensation component can support it in the installation area, providing effective positioning for the battery pack and compensating for the degree of looseness or wobbling of the battery pack in the installation area. This improves the tightness of the battery pack installation and helps prevent the stability of power transmission from being affected by shaking during vehicle operation.

[0044] According to the battery pack provided in the embodiments of this application, the battery pack may include an adapter member, which may be detachably connected to a first wall portion and a second wall portion, and may extend across a side portion and be detachably connected to the side portion. The adapter member may have a compensation connection area, and a compensation mounting portion may be detachably connected to the compensation connection area.

[0045] Thus, according to the battery pack provided in this application embodiment, the battery pack is detachably connected to the first wall, the second wall, and the side via a connecting member, making the entire housing detachable. This facilitates the replacement of structures such as the first wall, the second wall, and the side within the housing. Simultaneously, the connecting member also provides a compensating connection area for the compensating mounting portion, effectively reusing the connecting member. In other words, the connecting member serves as both a connecting structure forming the housing and a mounting position for the compensating component, thereby achieving component reuse. This contributes to a compact battery pack structure.

[0046] Furthermore, according to the battery pack provided in the embodiments of this application, the adapter also serves an isolation function. Here, as an example, the adapter prevents the compensation components from being directly connected to the housing, thereby increasing the insulation performance of the battery pack relative to the external environment, especially the battery pack mounting area of ​​the vehicle. In other words, the use of the adapter prevents connectors such as screws from directly penetrating the interior of the battery pack. These connectors not only lack insulation due to their metallic material, but excessive penetration into the housing can also lead to excessively tight spacing between the connectors and the individual cells within the battery pack. Moreover, when the battery pack is subjected to external impact, it is also detrimental to maintaining distance between the individual cells and the connectors. In other words, the adapter not only prevents excessive penetration of connectors into the housing, thus reducing electrical insulation performance, but also forms a buffer between the individual cells and the connectors.

[0047] According to the battery pack provided in the embodiments of this application, the compensation component may include a compensation fastening member, which may pass through the compensation mounting part and the adapter member, and may be detachably connected to the side. In the embodiments, it is equivalent to connecting the compensation mounting part and the adapter member to the side of the battery pack housing through the same connection structure, which effectively reduces the complexity of the battery pack.

[0048] According to the battery pack provided in the embodiments of this application, the number of adapter components can be multiple, and at least some of the adapter components are provided with compensation components. The number of at least some of the adapter components is at least two, so as to ensure that at least two compensation components can compensate for the space of the battery pack loosening and shaking in a more effective way. For example, when the compensation directions of the two compensation components intersect, it can be ensured that the battery pack can be freely adjusted in the horizontal plane to obtain any amount of compensation. Because when the two compensation directions intersect, the required compensation margin can be synthesized by adjustment.

[0049] According to the battery pack provided in the embodiments of this application, the battery pack further includes external terminals and adapter terminals. In the embodiments, the external terminals are electrically connected to the aforementioned plurality of individual battery cells. The adapter terminals can be spaced apart from the external terminals and electrically connected to the external terminals. The adapter terminals can change their positions in an alternating manner with the external terminals. Thus, the positions of the terminals for external electrical connection of the battery pack can also be adjusted through the adapter terminals. Therefore, after the battery pack is installed in the installation area, the positions of the adapter terminals of the battery pack can be fine-tuned according to the actual situation, further improving the adaptability of the battery pack.

[0050] According to the battery pack provided in the embodiments of this application, the battery pack further includes an adapter line electrically connecting an external terminal and an adapter terminal. The adapter line extends in a coiled and / or meandering manner between the external terminal and the adapter terminal. In the embodiments, the battery pack may further include a bent tube member, which may be sleeved on the outside of the adapter line. The cross-sectional area of ​​the end of the bent tube member near the external terminal is larger than the cross-sectional area of ​​the end near the adapter terminal. Therefore, when the adapter terminal moves relative to the external terminal, the bent tube member is less prone to bending deformation because it is relatively thicker on the external terminal side, while it is more prone to bending deformation because it is relatively thinner on the adapter terminal side.

[0051] Therefore, the closer the adapter line is to the external terminal, the smaller the range of motion. This part of the line has relatively little movement, which helps to avoid the external terminal and adapter line from failing due to fatigue after multiple large movements, thus preventing the battery pack from experiencing a decline in electrical insulation performance.

[0052] According to the battery pack provided in the embodiments of this application, the external terminals, the adapter lines, and the bent tube components are all disposed within the space defined by the first wall, the second wall, and the side, thereby shielding the external terminals, the adapter lines, and the bent tube components and enhancing the electrical insulation performance of the battery pack.

[0053] According to the battery pack provided in the embodiments of this application, the compensation component may further include a first compensation member and a second compensation member. In the embodiments, the first compensation member is connected to the compensation mounting portion, the second compensation member is connected to the compensation support portion, and the second compensation member is movably connected to the first compensation member so that the compensation support portion can be close to and away from the housing.

[0054] In this embodiment, one of the first compensation member and the second compensation member is fitted over the other. Therefore, even at the extreme position where the compensation support can be furthest from the housing, the stability of the connection between the first and second compensation members can be ensured due to the fitted relationship.

[0055] According to the battery pack provided in the embodiments of this application, the first compensation member and the second compensation member are threadedly connected. The compensation assembly may further include a telescopic support member, which has two opposing ends. One end of the telescopic support member is connected to the first of the first and second compensation members, and the other end of the telescopic support member abuts against the second of the first and second compensation members. The telescopic support member has a tendency to elongate. In the embodiments, the telescopic support member always provides a preload to the first and second compensation members, thereby preventing the first compensation member from wobbling relative to the second compensation member.

[0056] According to the embodiments of this application, the aim is to provide a method to improve the tightness of the assembly between the battery pack and the vehicle chassis or battery compartment (that is, the installation area for installing the battery pack in the vehicle as mentioned above) through an external fastening structure. The compatibility between the battery pack and the vehicle can be improved by changing the number and position of the fastening structure and replacing related components. At the same time, the terminal position of the battery pack can be changed to obtain greater assembly flexibility.

[0057] The specific installation method of this application embodiment is as follows. A sealing plate 2 is placed on the top and bottom of the side shell 1. The battery pack body 3 is installed inside the space enclosed by the side shell 1 and the two sealing plates 2. Multiple evenly distributed threaded holes 101 are opened on the opposite side of the two sealing plates 2 and on both sides of the side shell 1. The upper and lower sealing plates 2 are fixed to the top and bottom of the side shell 1 respectively by multiple C-shaped fastening plates 5 and the first fastening bolt group 6.

[0058] In this embodiment, a C-shaped fastening plate 5 corresponds to four first fastening bolt groups 6 and four threaded holes 101. Two of the four threaded holes 101 are located on the side housing 1, and the remaining two threaded holes 101 are located on the two sealing plates 2 respectively. A first mounting plate 7 is provided on one side of one or more C-shaped fastening plates 5. The first mounting plate 7 is fixed to one side of the C-shaped fastening plate 5 by cooperating with the corresponding threaded holes 101 through two second fastening bolt groups 8.

[0059] In this embodiment, an adjusting screw cylinder 9 is fixedly installed on one side of the first mounting plate 7. An adjusting screw 10 is screwed into the inside of the adjusting screw cylinder 9. A rotating joint 11 is rotatably installed at one end of the adjusting screw 10. A second mounting plate 12 is installed at one end of the rotating joint 11. The rotating joint 11 and the second mounting plate 12 are rotatably connected.

[0060] In this embodiment, the second mounting plate 12 is fitted with a top plate 13 by two third fastening bolt groups 14, a limit telescopic rod 15 is installed between the first mounting plate 7 and the second mounting plate 12, one end of the adjusting screw 10 is fitted with a protective sleeve 16, and the other end of the protective sleeve 16 is fitted with the adjusting screw 9.

[0061] Thus, the first mounting plate 7, adjusting screw 9, adjusting screw 10, rotating joint 11, second mounting plate 12, top plate 13, limiting telescopic rod 15, and protective sleeve 16 constitute a fastening structure. By setting the fastening structure, if the battery pack body 3 is prone to loosening or shaking when the side shell 1, sealing plate 2, and the internal battery pack body 3 are installed inside the vehicle chassis or battery compartment, multiple fastening structures of the corresponding number can be installed on the corresponding positions on both sides of the sealing plate 2. The protective sleeve 16 is rotated to drive the adjusting screw 10 to rotate, causing the adjusting screw 10 to move spirally within the adjusting screw 9, thereby adjusting the distance between the top plate 13 and the first mounting plate 7. This allows the top plate 13 to ultimately press against the side wall of the chassis or battery compartment, thus limiting the overall position of the battery pack, improving the tightness of the battery pack installation, and preventing the stability of power transmission from being affected by shaking during vehicle operation.

[0062] In this embodiment, the first mounting plate 7 is assembled with the C-shaped fastening plate 5 via the second fastening bolt group 8, and the top plate 13 is assembled with the second mounting plate 12 via the third fastening bolt group 14. This makes both the first mounting plate 7 and the top plate 13 detachable structures. Therefore, the number and position of the first mounting plate 7 and the top plate 13 can be adjusted according to the actual shape and position of the vehicle chassis and battery compartment. At the same time, the top plate 13 can be replaced with different shapes to make the top plate 13 fit the internal structure of the battery compartment better, thereby obtaining more stable support and improving the adaptability of the battery pack.

[0063] In this embodiment, by providing a protective sleeve 16, the protective sleeve 16 can enclose the adjusting screw 10 and the connection between the adjusting screw 10 and the adjusting cylinder 9 inside, thereby providing dustproof and moisture-proof protection for the threaded engagement of the adjusting screw 10 and the adjusting cylinder 9, avoiding the impact of environmental factors on the meshing transmission of the adjusting cylinder 9 and the adjusting screw 10, and extending the service life of the adjusting cylinder 9 and the adjusting screw 10. By providing a C-shaped fastening plate 5, the C-shaped fastening plate 5 can not only lock the two sealing plates 2 to the top and bottom of the side shell 1, but also provide an installation position for the fastening structure.

[0064] In this embodiment, an external terminal 4 is installed on one side of the battery pack body 3, and the side shell 1 has a C-shaped structure. The opening of the side shell 1 corresponds to the position of the external terminal 4. An adapter socket 17 is inserted into the external terminal 4, and an adapter terminal 19 is installed on the adapter socket 17 through the power transmission line 18.

[0065] In this embodiment, an assembly plate 20 is sleeved on the adapter terminal 19. Threaded holes are provided on both sides of the opening of the side housing 1. The same slide plate 21 is slidably installed inside the two threaded holes. An assembly hole is provided in the middle of the slide plate 21. The assembly plate 20 is located inside the assembly hole. C-shaped clamping plates 22 are placed on the top and bottom of the slide plate 21. Both C-shaped clamping plates 22 are fixed to the slide plate 21 by the fourth fastening bolt group 23. The assembly plate 20 is restricted inside the assembly hole by the two C-shaped clamping plates 22.

[0066] In this embodiment, two slide rods 24 are fixed on the outward side of the slide plate 21. Two horizontal elongated sliding holes 103 are opened on the outward side of the two slide grooves 102. The two slide rods 24 are located inside the two slide grooves 102 respectively. A fastening screw 25 is installed on the outward end of each slide rod 24. A fastening nut 26 is screwed to one end of each fastening screw 25. By setting the slide rods 24, the adapter terminal 19 is assembled with the slide plate 21 through the assembly plate 20, the C-shaped clamping plate 22 and the fourth fastening bolt group 23, so that the adapter terminal 19 can move together with the slide plate 21.

[0067] Therefore, during battery pack installation, the sliding plate 21 can be slid according to the internal conditions of the vehicle chassis and battery compartment, thereby causing the adapter terminal 19 to move horizontally, changing the position of the adapter terminal 19. The fastening nut 26 is then used to screw it onto the fastening screw 25 and into contact with the side wall of the side housing 1, thus locking the sliding plate 21 and fixing the position of the adapter terminal 19. In this embodiment, the adapter terminal 19 is electrically connected to the external terminal 4 on one side of the battery pack body 3 via the power transmission line 18 and the adapter socket 17. Therefore, the vehicle can connect to the external terminal 4 via the adapter terminal 19, allowing the terminal position of the battery pack to be finely adjusted according to actual conditions, further improving the adaptability of the battery pack.

[0068] In this embodiment, a connecting screw ring 27 is installed on one side of the battery pack body 3, and an external terminal 4 is located inside the connecting screw ring 27. A folded bend 28 is installed on one side of the assembly plate 20, and a power transmission line 18 is located inside the folded bend 28. One end of the folded bend 28 is screwed onto the connecting screw ring 27.

[0069] In this embodiment, the inner diameter of the folded bend 28 gradually decreases towards the mounting plate 20, making one end of the folded bend 28 funnel-shaped. By setting the folded bend 28, the folded bend 28 can wrap the power transmission line 18, the adapter socket 17 and the external terminal 4 inside, thereby protecting the power transmission line 18, the adapter socket 17 and the external terminal 4, restricting the power transmission line 18, reducing the swaying amplitude of the power transmission line 18, and ensuring the stability of the connection between the adapter socket 17 and the external terminal 4, thereby improving the stability of the battery pack power transmission.

In the embodiments, the vehicle may be, for example, a new energy vehicle, and the battery pack is a substantial power battery pack, from which at least a portion of the vehicle's power may come.

Any equivalent structural transformations made based on the innovative concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
