These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. The following embodiments and features in the embodiments can be combined with each other unless there is a conflict.

[0031] As described in the background technology, the battery pack includes a battery module and a battery box for accommodating the battery module. The battery module includes multiple battery cells, two side plates and two end plates, etc. The two side plates and two end plates together form a storage space for accommodating multiple battery cells.

[0032] End plates are used to connect to the ends of the battery module and secure the battery module to the corresponding mounting components within the battery pack. Side plates are used to connect to the sides of the battery module to connect to the individual cells within the battery module, providing stable mounting support for each cell. Therefore, because the end plates and side plates of existing battery modules have different functions, they need to be molded and processed separately, which is costly.

[0033] In order to overcome the defects in the prior art, the embodiments of the present application provide a battery module plate, a battery module, and a battery pack. The battery module plate includes a plate body and a connector. The plate body is connected to the side or end face of the battery module cell group. The connector is connected to the mounting component in the battery pack and at least one of the connectors of other battery module plates. The battery module plate provided in the embodiments of the present application can be used to sequentially connect to the peripheral side of the battery cell group without the need to separately process the end plate and the side plate. This makes the battery module plate highly versatile and more convenient to use. In addition, the battery module can be connected to the mounting component or other battery modules at both the end and the side of the battery module through the connector on the battery module plate. This further improves the versatility of the battery module plate while increasing the flexibility of the battery module layout and achieving stable installation of the battery module.

[0034] The content of the utility model will be described in detail below with reference to the accompanying drawings so that those skilled in the art can understand the content of the utility model more clearly and in detail.

[0035] Reference Figures 1 to 5 As shown, an embodiment of the present application provides a battery module panel 100, including a panel body 110 and at least one connector 120 arranged on the panel body 110, the connector 120 is located on one side of the panel body 110, and the side of the panel body 110 facing away from the connector 120 is used to connect with the end face or side face of the battery cell group 200, and the connector 120 is used to connect with the mounting components in the battery pack and at least one of the connectors 120 of other battery module panels 100.

[0036] It can be understood that the battery module panel 100 provided in the embodiment of the present application can be used for a CTM battery pack (Cell To Module), which is formed by connecting the battery cells 210 in series to form a module, and then assembling multiple modules together into a battery pack, or it can also be used for a CTP battery pack (Cell To Pack), which can be understood as a battery pack with only one battery module. This battery pack skips the standardized module link and directly integrates the battery cells 210 in the battery pack in sequence to improve space utilization and energy density.

[0037] The battery module panel 100 includes a panel 110 and at least one connector 120 disposed on the panel 110. The panel 110 and the connector 120 are integrally formed. The connector 120 is located on one side surface of the panel 110 to facilitate stable connection between the connector 120 and the panel 110. The side surface of the panel 110 facing away from the connector 120 can be connected to the end face or side face of the cell group 200. The cell group 200 refers to a plurality of cells 210 arranged in sequence in a group within the battery module. The two end faces of the cell group 200 correspond to the larger sides of the two cells 210 located at the first and last positions of the cell group 200, respectively. The two side faces of the cell group 200 correspond to the smaller sides of each cell 210, respectively, and are formed together after the cells are arranged in sequence.

[0038] During implementation, the end faces or side faces of the board 110 and the battery cell group 200 may be connected by bonding. For example, the adhesive may be structural adhesive, double-sided tape, or polyurethane adhesive. Structural adhesive can provide sufficient connection strength between the board 110 and the battery cell group 200, double-sided tape bonding is low-cost and easy to operate, and polyurethane adhesive has good bonding properties and good waterproof, moisture-proof, and aging resistance. This application does not impose any specific restrictions on the choice of adhesive, and the adhesive may be selected based on needs.

[0039] By utilizing the battery module plate 100, the plate body 110 is connected to the end face and side face of the battery cell group 200 respectively to form a battery module. Then, the battery module can be connected to the corresponding mounting components of the battery pack to realize the assembly of the battery pack. Among them, the connector 120 is connected to the corresponding mounting component of the battery pack, that is, the connector 120 can be connected to the connecting beam or connecting frame of the battery pack. For CTM battery packs, each battery module also needs to be connected to ensure the structural stability of the battery pack. Therefore, the connector 120 of each battery module can be connected to the connecting beam or connecting frame of the battery pack respectively. For some battery pack structures, there is no connecting beam between two adjacent battery modules. In this case, an additional connecting plate can be provided to connect the connector 120 on the battery module through the connecting plate to realize the connection between the battery modules.

[0040] Furthermore, since the battery module plate 100 provided in the embodiment of the present application has a connector 120, and the battery module plate 100 is respectively connected to the end face and side face of the battery cell group 200, when the battery module is specifically assembled into the battery pack, the end of the battery module can be connected to the mounting component of the battery pack through the connector 120, or the side of the battery module can be connected to the mounting component of the battery pack through the connector 120 according to the internal layout of the battery pack. The installation layout is more flexible and convenient, and the present application does not impose any restrictions on this.

[0041] Similarly, refer to Figure 6 and Figure 7As shown, when two adjacent battery modules are connected, the ends of the two battery modules may be connected to each other, or the sides of the two battery modules may be connected to each other according to the internal layout requirements of the battery pack. This application does not impose any restrictions on this.

[0042] Therefore, the battery module plate 100 provided in the embodiment of the present application includes a plate body 110 and a connector 120. The plate body 110 is connected to the side or end surface of the battery module cell group 200, and the connector 120 is connected to the mounting components in the battery pack and at least one of the connectors 120 of other battery module plates 100. As a result, the battery module plate 100 provided in the embodiment of the present application can be used to sequentially connect to the peripheral sides of the battery cell group without the need to separately process the end plate and side plate. This makes the battery module plate 100 highly versatile and more convenient to use. In addition, the battery module can be connected to the mounting components or other battery modules at both the end and side portions of the battery module through the connector 120 on the battery module plate 100. This further improves the versatility of the battery module plate 100 while increasing the flexibility of the battery module layout and achieving stable installation of the battery module.

[0043] In some embodiments, reference Figures 1 to 3 As shown, the connector 120 includes a connecting base 121 and a plurality of connecting ears 122 spaced apart on the connecting base 121 . The connecting base 121 is connected to the board 110 , and the connecting ears 122 are used to connect the mounting components to at least one of the connectors 120 of other battery module boards 100 .

[0044] It is understood that, when specifically configured, the dimensions of the plate 110 can be set with reference to the desired battery module dimensions. The connecting base 121 is connected to the plate 110 and is located on one side of the plate. The height of the connecting base 121 relative to the plate 110 can also be set based on the height of the corresponding mounting component of the battery pack, that is, based on the height of the connecting beam or connecting frame, so that the connecting member 120 can be smoothly connected to the mounting component and improve the stability of the connection between the connecting member 120 and the mounting component.

[0045] A plurality of connecting ears 122 are arranged on the connecting base 121 at intervals in sequence, so that the connecting base 121 is connected to the mounting part or other battery module through the connecting ears 122. By setting a plurality of connecting ears 122, when the connecting member 120 is connected to the mounting part or other battery module, each connecting ear 122 can form a corresponding connection point, thereby realizing the connection between the connecting member 120 and the mounting part or other battery module through a plurality of connection points along the connecting member 120, thereby ensuring the stability of the connection of the connecting member 120 and ensuring the stability and reliability of the battery pack assembly.

[0046] Among them, reference Figures 1 to 4As shown, a spacing gap 123 is formed between two adjacent connecting ears 122 , and the length of the spacing gap 123 is greater than or equal to the length of the connecting ears 122 .

[0047] It is understood that the connecting ears 122 are arranged in sequence and spaced apart, so that a spacing gap 123 can be formed between two adjacent connecting ears 122. When two adjacent battery modules are connected to each other, in order to make the battery module docking more compact, reduce the space occupied by the battery module, and improve the space utilization rate within the battery pack, the connectors 120 of the two battery modules can be docked with each other, that is, the connecting ears 122 of one connector 120 are inserted into the spacing gap 123 between the two connecting ears 122 of the other connector 120. In this way, by making the length of the spacing gap 123 greater than or equal to the length of the connecting ears 122, the connecting ears 122 can be stably inserted into the spacing gap 123, and the connecting ears 122 on both sides of the spacing gap 123 will not interfere with each other due to the spacing gap 123 being too small.

[0048] Further, refer to Figure 4 As shown, the shape of the connecting ear 122 matches the shape of the spacing gap 123 .

[0049] It is understood that the edge shape of the spacing notches 123 corresponding to the connecting ears 122 is often determined by the shape of the connecting ears 122. Thus, the connecting ears 122 can be arranged at regular intervals, and the length of the connecting ears 122 can be made consistent with the length of the spacing notches 123, so that the shape of the connecting ears 122 can still match the shape of the spacing notches 123 after being rotated 180 degrees. When two connecting members 120 are docked, the connecting ears 122 of one connecting member 120 can be stably embedded in the spacing notches 123 of the other connecting member 120, so that the connecting ears 122 of the two connecting members 120 are alternately arranged along the extension direction of the connecting base 121.

[0050] Such a setting can effectively improve the space utilization of the connector 120, and achieve the goal of increasing the number of connecting ears 122 as much as possible within a certain space, thereby increasing the number of connection points between the connector 120 and the mounting components or other battery modules, making the connection between the connector 120 and the mounting components or other battery modules more stable.

[0051] In specific implementation, the present application does not impose any restrictions on the shape of the connecting ear 122. The connecting member 120 can be an axially symmetrical figure or an asymmetrical figure. As long as the connecting ear 122 and the spacing gap 123 with the same length as itself can be alternately arranged in sequence, the connecting ear 122 and the spacing gap 123 of another connecting member 120 can be interlocked.

[0052] In some embodiments, reference Figure 3and Figure 4 As shown, the connecting ear 122 is an axisymmetric connecting ear 122 , and the axis of symmetry of the connecting ear 122 is perpendicular to the plate body 110 .

[0053] It is easy to understand that setting the connecting ear 122 as an axially symmetrical figure can make the structure of the connecting ear 122 simpler, and thereby simplify the structure of the spacing gap 123, making it easier for the connecting ear 122 and the spacing gap 123 to match and embed with each other, while simplifying the processing design of the connecting part 120.

[0054] In a specific implementation, the axially symmetrical figure can be set to a trapezoid, a triangle or a semicircle, etc., so that the size of the side of such axially symmetrical figure close to the connecting base 121 is larger than the size of the side away from the connecting base 121. In this way, when the two connecting parts 120 are assembled with each other, the spacing gap 123 can form a flared opening adapted to the connecting ear 122, so that the connecting ear 122 can be spliced ​​in a direction parallel to it, or the connecting ear 122 can also be spliced ​​in a direction perpendicular to it, making the connection between the two connecting parts 120 more flexible and convenient.

[0055] In other embodiments, the dimension of the axially symmetrical figure away from the connecting base 121 can also be set to be larger than the dimension of the side close to the connecting base 121. For example, the connecting ear 122 is set to be a trapezoid, so that the short side of the trapezoid is connected to the connecting base 121. In this way, when the two connecting members 120 are assembled with each other, the connecting ear 122 can only be embedded in the spacing notch 123 in a direction perpendicular to them, thereby preventing the connecting ear 122 from separating from the spacing notch 123 in a direction parallel to itself, further ensuring the reliability of the assembly of the connecting ear 122 and the spacing notch 123.

[0056] In some embodiments, reference Figure 3 and Figure 4 As shown, at least one connecting hole 1221 is provided on the connecting ear 122 .

[0057] It can be understood that a connecting hole 1221 is provided on the connecting ear 122, so that a bolt or other fastener can pass through the connecting hole 1221 and connect to the connecting beam or connecting frame to fix the connecting ear 122 to the mounting component of the battery pack.

[0058] Among them, setting the connecting hole 1221 on the isosceles line of the connecting ear 122 can ensure that the center line of each connecting hole 1221 is located on a straight line on the same side of the connecting base 121. When the connecting ear 122 is subsequently connected to the connecting beam or connecting frame through the connecting hole 1221, it is only necessary to open a row of corresponding through holes on the connecting beam or connecting frame, making the fastening and installation of the fasteners easier.

[0059] Moreover, when the two connecting members 120 are assembled with each other and connected to the same connecting beam, the two connecting members 120 can also share the same row of through holes on the connecting beam, without the need to respectively set two rows of through holes on the connecting beam to correspond to the connecting holes 1221 on the two connecting members 120, thereby effectively reducing the width requirement of the connecting beam, simplifying the battery pack structure, and facilitating disassembly and assembly.

[0060] Further, refer to Figure 3 and Figure 4 As shown, at least two connection holes 1221 are spaced apart on the connection ear 122 , and the spacing direction of the connection holes 1221 is consistent with the spacing direction of the connection ears 122 .

[0061] When two adjacent battery modules need to be connected and no connecting beam is provided between them, a connecting piece is required to connect the two connected lugs 122 after they are assembled together to ensure module rigidity. To achieve this, two connecting holes 1221 can be provided on each connecting lug 122 at intervals, with the spacing of the connecting holes 1221 aligned with the spacing of the connecting lugs 122 on the connecting base 121. This allows the connecting piece to sequentially connect two relatively close connecting holes 1221 on the two connecting lugs 122.

[0062] In some embodiments, reference Figures 1 to 3 As shown, the connecting member 120 is offset toward one side edge of the plate body 110 .

[0063] It can be understood that when the connecting member 120 is not connected to the connecting beam and is only connected to other connecting members 120 through the connecting plate, the connecting member 120 can be set to be biased toward one side of the plate body 110, so that the connecting member 120 is relatively located on the upper part of the plate body 110, and the operating space for the connecting plate connection is wider, which is convenient for the installation of the connecting plate.

[0064] In some embodiments, reference Figures 1 to 3 As shown, the extension direction of the connecting member 120 is consistent with the extension direction of the plate body 110 , and the two ends of the plate body 110 are flush with the two ends of the connecting member 120 .

[0065] It can be understood that the extension direction of the connector 120 is consistent with the extension direction of the plate 110, that is, the height of the connector 120 along the extension direction of the plate 110 is consistent, so that the connector 120 can be stably connected to the mounting components of the battery pack or other battery modules.

[0066] The two ends of the plate body 110 are flush with the two ends of the connecting piece 120, which means that the connecting piece 120 is continuously arranged along the extension direction of the plate body 110. In this way, the battery module plate 100 as long as possible can be produced in advance. When the battery module is assembled, the battery module plate 100 of corresponding length can be flexibly cut according to the number and size of the battery cell group 200, and connected to the end or side of the battery cell group 200 respectively, thereby further improving the versatility of the battery module plate 100. Moreover, no matter what length the plate body 110 adopts, a connecting piece 120 of corresponding length is provided on the plate body 110.

[0067] An embodiment of the present application further provides a battery module, comprising a module body and any one of the above-mentioned battery module panels 100 , wherein the battery module panel 100 is connected to the module body.

[0068] The battery module plate 100 has been described in detail in the above embodiment and will not be repeated here.

[0069] In addition, an embodiment of the present application also provides a battery pack, including a battery pack body and any one of the above-mentioned battery modules, wherein the battery module is connected to the battery pack body.

[0070] Among them, the battery module plate 100 in the battery module is described in detail in the above embodiment, and the structure of the battery module can be understood accordingly, and this application will not elaborate on it again.

[0071] In summary, the battery module and battery pack provided in the embodiments of the present application are provided with a battery module plate 100, which includes a plate body 110 and a connector 120. The plate body 110 is connected to the side or end face of the battery cell group 200 of the battery module, and the connector 120 is connected to the mounting components and at least one of the other battery modules in the battery pack. As a result, the plate body 110 can act as an end plate connected to the end face of the battery cell group 200, or as a side plate connected to the side face of the battery cell group 200, as required. This makes the battery module plate 100 highly versatile and more convenient to use. In addition, the battery module plate 100 can also be connected to the mounting components or other battery modules through the connector 120, further improving the versatility of the battery module plate 100 while also achieving stable installation of the battery module.
