Description

TECHNICAL FIELD

[0001] The present application relates to the field of household appliances, in particular to a battery assembly for a vehicle and the vehicle. BACKGROUND

[0002] In the related art, the ends of two adjacent rows of battery assemblies are often electrically connected by external copper bars. The battery connection pads on the electrical isolation plate need to be welded with output copper bars for connection with the external copper bars. In order to fix the external copper bars, a copper bar base, a protective cover and a fixing buckle need to be installed at the corresponding positions of the isolation plate to prevent the external copper bars from falling off. However, since many parts need to be installed, the cumulative error of the installed parts is large, which leads to low connection accuracy. In the working condition, the connection is prone to looseness, the internal resistance increases, and the power cannot be output.

[0033] Embodiments of the present application are described in detail below with reference to the attached drawings, wherein the same or like reference numerals in different drawings denote the same or like elements or elements having the same or similar functions. The embodiments described below are examples only, and are not intended to limit the present application.

[0034] Reference is made to Figures 1-4 A battery assembly 100 for a vehicle according to an embodiment of the present application is described below.

[0035] The battery assembly 100 for a vehicle according to the embodiment of the present application comprises battery monomers 1, a first collecting plate 2, a second collecting plate 3 and a cross-connection row 4. The battery monomers 1 are provided with poles 11. The battery monomers 1 are arranged in a column in the first direction. The battery monomers 1 are arranged in multiple columns in the second direction. Adjacent two battery assemblies are a first column of battery monomers 12 and a second column of battery monomers 13. The first collecting plate 2 is arranged in the first column of battery monomers 12. The first collecting plate 2 is electrically connected with the poles 11 of the battery monomers 1 in the first column of battery monomers 12. The second collecting plate 3 is arranged in the second column of battery monomers 13. The second collecting plate 3 is electrically connected with the poles 11 of the battery monomers 1 in the second column of battery monomers 13. The cross-connection row 4 is provided with a first connecting part 41 and a second connecting part 42. The first connecting part 41 is connected with the poles 11 of the battery monomers 1 at the end of the first column of battery monomers 12. The second connecting part 42 is connected with the poles 11 of the battery monomers 1 at the end of the second column of battery monomers 13. The cross-connection row 4 extends in the second direction. The first connecting part 41 and the second connecting part 42 are arranged at the two ends of the cross-connection row 4 in the extending direction. The first connecting part 41 and the second connecting part 42 cover one end of the corresponding pole 11 in the thickness direction.

[0036] It can be understood that when the first connecting part 41 and the second connecting part 42 of the cross-connection row 4 cover one end of the corresponding pole 11 for connection, the problem that the cross-connection row 4 and the pole 11 are more likely to displace or loosen when the battery assembly is subjected to external forces such as vibration and impact caused by point contact or small area contact connection is avoided. During the driving of the vehicle, bumps and vibrations are generated. The connection of the connecting part of the cross-connection row 4 can rely on the large frictional force of the contact and the close fit between the connecting part and the pole 11 to effectively resist the influence of external forces on the connection stability. Because the connecting part and the pole 11 are covered and connected in the thickness direction, the mechanical strength of the connection between the connecting part and the pole 11 is higher. In the long-term use process, this connection mode can also maintain a relatively stable connection state, reduce the risk of connection reliability caused by environmental factors, and improve the installation reliability of the cross-connection row 4 between the battery assemblies.

[0037] Specifically, the battery monomers 1 are arranged in a column in the first direction. Multiple columns of battery monomers are arranged in parallel in the second direction. The cross-connection row 4 extends along the second direction and connects the poles 11 at the ends of the adjacent two columns of battery monomers, so that the cross-connection row 4 can be closely combined with the structure of the battery assembly during installation, utilize the space of the battery assembly, and better withstand the stress that the battery assembly may generate in different directions during connection. When the vehicle accelerates or decelerates, the battery assembly may generate stress in the front-rear direction in the vehicle cabin. The cross-connection row 4 can effectively disperse and resist these stresses through the connection with the pole 11 and its own structure, ensure the reliability of the connection, and thus improve the installation reliability.

[0038] In the battery assembly 100, the battery cells 1 are configured as the first column of battery groups 12 and the second column of battery groups 13 in parallel, the first collecting plate 2 is electrically connected with the plurality of battery cell 1 pole posts 11 of the first column of battery groups 12, and the second collecting plate 3 is electrically connected with the plurality of battery cell 1 pole posts 11 of the second column of battery groups 13, which lays a foundation structure for signal collection and circuit connection inside the battery group.

[0039] The jumper row 4 plays a role of connecting the first column of battery groups 12 and the second column of battery groups 13, and the jumper row 4 is configured to extend in the second direction, and the jumper row 4 is provided with the first connecting part 41 and the second connecting part 42 at both ends in the extending direction, respectively, and is connected with the battery cell 1 pole posts 11 at the end of the battery group of the corresponding column, since the first connecting part 41 and the second connecting part 42 cover one end of the corresponding pole post 11 in the thickness direction, respectively, a larger contact area is provided, which can better disperse the current when connected, reduce the heating and poor connection caused by excessive local current, and at the same time, since the first collecting plate 2 is electrically connected with the plurality of battery cell 1 pole posts 11 of the first column of battery groups 12, and the second collecting plate 3 is electrically connected with the plurality of battery cell 1 pole posts 11 of the second column of battery groups 13, the jumper row 4 is provided with the first connecting part 41 and the second connecting part 42, respectively, and is connected with the battery cell 1 pole posts 11 at the end of the battery group of the corresponding column, the jumper row 4 realizes the internal signal collection and circuit connection between the first column of battery groups 12 and the second column of battery groups 13.

[0040] The first direction is perpendicular to the second direction.

[0041] According to some embodiments of the present application, the battery assembly 100 for a vehicle further comprises an isolation plate 5, the isolation plate 5 is provided one-to-one with the pole post 11 of the battery cell 1, one side of the isolation plate 5 in the thickness direction covers the end of the pole post 11 and is electrically connected with the pole post 11, and the other side of the isolation plate 5 in the thickness direction is attached to and connected with the jumper row 4.

[0042] The isolation plate 5 covers the end of the pole column 11, and compared with the originally exposed end surface of the pole column 11, the isolation plate 5 increases the contact range with the pole column 11. Since the isolation plate 5 has a certain area and can closely fit the end of the pole column 11, on the connection interface between the pole column 11 and the isolation plate 5, the current conduction is no longer limited to the originally small end surface area of the pole column 11, but is dispersed to the entire area where the isolation plate 5 and the pole column 11 are in contact, thereby effectively increasing the initial contact area at the pole column 11. The other side of the isolation plate 5 in the thickness direction is attached to and connected with the jumper row 4. The isolation plate 5 provides a larger and more flat connection basis for the jumper row 4 compared with the end surface area of the pole column 11. When the jumper row 4 is attached to the isolation plate 5, it is in contact with the entire surface of the isolation plate 5, thereby expanding the contact area at the connection between the jumper row 4 and the battery monomer 1. After the isolation plate 5 is arranged, the jumper row 4 can be attached to the larger flat surface of the isolation plate 5, so that the contact area is significantly improved based on the original basis. Through the arrangement of the isolation plate 5 between the pole column 11 and the jumper row 4, the contact area is expanded at the connection end of the pole column 11 and the connection end of the jumper row 4 respectively, thereby further improving the contact area, which is conducive to the stable transmission of current, reduces the contact resistance and heating problems, and improves the performance and reliability of the battery assembly 100 as a whole.

[0043] According to some embodiments of the present application, the battery assembly 100 for a vehicle is provided with a first positioning part 51 formed on the isolation plate 5 and a second positioning part 43 formed on the jumper row 4 and capable of limiting cooperation with the first positioning part 51.

[0044] The first positioning part 51 and the second positioning part 43 provide guidance for the connection between the jumper row 4 and the isolation plate 5. The second positioning part 43 can quickly and accurately limit cooperation with the first positioning part 51, thereby avoiding the deviation of the relative position between the jumper row 4 and the isolation plate 5 due to human judgment errors or improper operation during installation. The time-consuming repeated adjustment of the position of the jumper row 4 to achieve accurate connection during installation is avoided, thereby significantly improving the accuracy and efficiency of installation and reducing the assembly time and cost.

[0045] Since the jumper row 4 and the isolation plate 5 are limited to cooperate through the first positioning part 51 and the second positioning part 43, a stable mechanical constraint is formed. When the vehicle runs on a rough road and generates strong vibration, the jumper row 4 can be prevented from being displaced horizontally or vertically relative to the isolation plate 5, which can cause the connection to be loose or even disconnected, thereby affecting the stability of the electrical connection between the battery groups. The relative position between the jumper row 4 and the isolation plate 5 is fixed, which can effectively resist the interference of external force and maintain a close connection state, thereby ensuring that the battery assembly 100 always maintains stable electrical connection in a harsh vehicle operating environment, and further ensuring the reliable operation of the vehicle power system.

[0046] According to the battery assembly 100 for a vehicle of some embodiments of the present application, one of the first positioning part 51 and the second positioning part 43 is configured as a positioning protrusion, and the other of the first positioning part 51 and the second positioning part 43 is configured as a positioning hole.

[0047] Further, in the installation process of the battery assembly 100, the structure of the positioning protrusion and the positioning hole provides installation guidance for the connection of the cross-over row 4 and the isolation plate 5. When installing the cross-over row 4 on the isolation plate 5, the operation can be performed by aligning the positioning protrusion with the positioning hole. When installing, the cross-over row 4 is simply picked up, the positioning protrusion is found to correspond to the positioning hole and inserted, and the preliminary positioning can be quickly realized, without spending a lot of time to repeatedly try different docking angles and positions, improving the convenience of installation. The protrusion and hole matching mode can realize positioning. The shape and size of the positioning hole are matched with the positioning protrusion. After the positioning protrusion is accurately inserted into the positioning hole, the relative position of the cross-over row 4 and the isolation plate 5 in the plane is fixed, avoiding the installation position deviation caused by human error, ensuring that the cross-over row 4 and the isolation plate 5 are in the corresponding position after installation is completed, thereby laying a good foundation for the subsequent normal operation of the battery assembly 100.

[0048] According to the battery assembly 100 for a vehicle of some embodiments of the present application, the first connecting part 41 is formed with a first recess 411 opposite to the corresponding pole 11, and the second connecting part 42 is formed with a second recess 421 opposite to the corresponding pole 11.

[0049] It can be understood that the thicknesses of the first recess 411 and the second recess 421 are thinner than the thicknesses of other positions of the first connecting portion 41 and the second connecting portion 42. During the welding process, the heat transfer and distribution have an influence on the welding quality. The thinner thicknesses of the first recess 411 and the second recess 421 mean that, during welding, the heat transferred from the welding point to the areas of the first recess 411 and the second recess 421 can more quickly make the metal in the areas reach a molten state. The thinner first recess 411 and the second recess 421 can more efficiently absorb welding heat, so that, under the same welding energy input, the first recess 411 and the second recess 421 can more quickly reach the required temperature for welding and achieve melting. When the welding heat source acts on the contact areas of the first connecting portion 41 and the second connecting portion 42 and the pole column 11, the heat is preferentially concentrated in the first recess 411 and the second recess 421 and the vicinity thereof, which can more easily melt the metal at the welding position between the first recess 411 and the second recess 421 on the first connecting portion 41 and the second connecting portion 42 and the pole column 11, thereby achieving good penetration. Once the penetration is achieved, the metal between the first connecting portion 41 and the second connecting portion 42 and the pole column 11 is sufficiently fused at the welding position, forming a continuous and uniform metal bonding area, so that the connection strength and stability between the cross-over row 4 and the isolation plate 5 are improved. During the operation of the vehicle, the battery assembly 100 will be subjected to external forces. The firm connection achieved by the penetration of the first recess 411 and the second recess 421 can effectively resist these external forces, ensuring that the electrical connection between the battery assemblies always remains stable and reliable and does not loosen or break due to external forces, thereby ensuring stable operation of the entire battery assembly 100 during long-term use of the vehicle and providing continuous and reliable power support for the power system of the vehicle.

[0050] It should be noted that, as shown in Figure 3 the thicknesses of the first recess 411 and the second recess 421 are T1, the thickness of the isolation plate 5 is T2, and the thickness of the cross-over row 4 is T, which satisfy T1+T2≤T. Since the first recess 411 and the second recess 421 are designed for easy welding, when the welding equipment applies heat to the connecting parts of the cross-over row 4, the isolation plate 5, and the pole column 11, the thinner total thickness allows the heat to reach the molten state of the welding interface without penetrating through thick materials, avoiding the situation that the heat is difficult to penetrate due to excessive thickness. Under the condition of satisfying the thickness, the heat can more concentratedly act on the welding area, and the penetration is more easily achieved, that is, the metal between the cross-over row 4, the isolation plate 5, and the pole column 11 is sufficiently fused at the welding position, forming a firm metallurgical bond.

[0051] According to some embodiments of the battery assembly 100 for vehicles, the first connecting piece 6 is configured in multiple and connects the pole 11 of each battery monomer 1 in the first column battery group 12 to the first collecting plate 2 respectively, and the second connecting piece 7 is configured in multiple and connects the pole 11 of each battery monomer 1 in the second column battery group 13 to the second collecting plate 3 respectively.

[0052] The first collecting plate 2 and the second collecting plate 3 are arranged to facilitate the data collection of the battery monomer 1, the first connecting piece 6 is configured in multiple and connects the pole 11 of each battery monomer 1 in the first column battery group 12 to the first collecting plate 2 respectively, and the second connecting piece 7 is configured in multiple and connects the pole 11 of each battery monomer 1 in the second column battery group 13 to the second collecting plate 3 respectively, so that the first collecting plate 2 and the second collecting plate 3 can obtain the electrical parameters of each battery monomer 1 in each column battery group for subsequent analysis and processing, which can ensure the safe operation of the battery assembly 100, and the connection of multiple first connecting pieces 6 and multiple second connecting pieces 7 increases the redundancy of signal transmission, so that even if a connecting piece fails, other connecting pieces can still ensure signal transmission, thereby improving the reliability of the system.

[0053] According to some embodiments of the battery assembly 100 for vehicles, the first connecting piece 6 connects the first connecting row 61 to the first collecting plate 2, and the second connecting piece 7 connects the second connecting row 71 to the second collecting plate 3.

[0054] In the battery assembly 100, the first column battery group 12 and the second column battery group 13 are connected in stages, for the first column battery group 12, the first connecting piece 6 connects the first connecting row 61 to the first collecting plate 2, and for the second column battery group 13, the second connecting piece 7 connects the second connecting row 71 to the second collecting plate 3, so that the current transmission path in the battery group is clearer and more orderly, and when the battery group is charged and discharged, the current is first conducted and integrated between the adjacent battery monomers 1 through the first connecting row 61 and the second connecting row 71, and then transmitted to the first collecting plate 2 and the second collecting plate 3 through the first connecting piece 6 and the second connecting piece 7, respectively, so that the current can be transmitted efficiently and stably according to the designed path, thereby improving the electrical connection efficiency of the entire battery assembly 100.

[0055] It should be noted that at least one of the first connecting piece 6 and the second connecting piece 7 is arranged on the jumper row 4, when the first connecting piece 6 is arranged on the jumper row 4, the first connecting piece 6 connects the jumper row 4 and the first collecting plate 2, when the second connecting piece 7 is arranged on the jumper row 4, the second connecting piece 7 connects the jumper row 4 and the second collecting plate 3, the jumper row 4 can replace the functions of the first connecting row 61 and the second connecting row 71 at the jumper position, avoiding the need to additionally lay a layer of circuit of the first connecting row 61 or the second connecting row 71, reducing the need for separate laying of the circuit, thereby simplifying the layout of the circuit connection, avoiding the problem of space congestion and complex circuit management caused by excessive circuit inside the battery assembly 100, and improving the space utilization rate inside the battery assembly 100.

[0056] According to some embodiments of the battery assembly 100 for a vehicle of the present application, the first collecting plate 2 and the second collecting plate 3 each comprise a collecting plate body 31 and a connecting rib 32, the collecting plate body 31 is arranged at the top of the battery, both sides of the collecting plate body 31 are respectively formed with a connecting gap 311, the connecting rib 32 is accommodated in the connecting gap 311 and is arranged in the width direction of the collecting plate body 31 and spaced from the inner wall of the connecting gap 311, at least one end of the connecting rib 32 in the extension direction of the collecting plate body 31 is connected with the inner wall of the connecting gap 311, and the connecting rib 32 is adapted to be connected with the first connecting piece 6 or the second connecting piece 7.

[0057] Since at least one end of the connecting rib 32 in the extension direction of the collecting plate body 31 is connected with the inner wall of the connecting gap 311, the connecting rib 32 is adapted to be connected with the first connecting piece 6 or the second connecting piece 7, the first connecting piece 6 and the second connecting piece 7 are protruding from the plane of the collecting plate body 31, the vibration of the vehicle will preferentially deform at the connection between the first connecting piece 6 and the second connecting piece 7 and the collecting plate body 31, and during the shaking of the vehicle, the collecting plate body 31 can be buffered and protected by the deformation of the connecting rib 32 at the connecting gap 311, the connecting rib 32 can disperse and buffer the displacement and external force generated, ensuring that the collecting plate body 31 is in a relatively stable and less stressed state, avoiding damage to the collecting plate body 31 caused by external forces in complex road conditions, and further protecting the integrity and functionality of the collecting plate body 31 in various use scenarios.

[0058] The structure connecting the gap 311 and the connecting rib 32 provides guidance and positioning for the installation of the first connecting sheet 6 or the second connecting sheet 7. When the first connecting sheet 6 or the second connecting sheet 7 needs to be connected with the connecting rib 32, the connecting gap 311 makes the position of the connecting rib 32 clear, so that the installer can quickly find the position of the connecting rib 32. Moreover, since the connecting rib 32 is spaced apart from the inner wall and at least one end is connected in the connecting gap 311, the installer can connect the first connecting sheet 6 or the second connecting sheet 7 with the connecting rib 32 according to the characteristics, avoiding installation difficulties and errors caused by the inability to find the accurate position or unclear connection method. The installation guidance and positioning improve the installation efficiency of the battery assembly 100 and reduce the installation time and labor cost.

[0059] Further, in some embodiments of the present application, the connecting rib 32 can be a flexible member, which can enhance the deformation effect, reduce the frequency of material replacement, and improve the buffering performance.

[0060] According to some embodiments of the battery assembly 100 for a vehicle of the present application, the connecting rib 32 is formed with a bending section 321 in the extension direction.

[0061] When the connecting rib 32 is subjected to external force, the presence of the bending section 321 changes the force transmission path and stress distribution, avoiding the single stress structure of the straight-line type structure. The geometry of the bending section 321 enables the connecting rib 32 to produce more deformation when subjected to force. During the driving process of the vehicle, the impact force is transmitted to the connecting rib 32, and the straight-line connecting rib 32 mainly relies on its own stretching or compression to cope with external force, and the degree of its deformability is relatively limited. However, the bending section 321 can work synergistically through various deformation modes such as bending and twisting, more effectively absorbing and dispersing the impact force.

[0062] When the impact force causes the bending section 321 to deform, the stress inside the material gradually accumulates, converting the impact energy into its own elastic potential energy. The bending section 321 can store more energy than the straight section under the same stress level. When the impact force weakens or disappears, the bending section 321 can restore to its original shape or a shape close to the original shape by using its stored elastic potential energy, releasing the stored energy, further reducing the possibility of permanent deformation or damage of the connecting rib 32 due to force. This can fully utilize the high strength advantage of the material, while ensuring that the connecting rib 32 will not be easily damaged when subjected to impact, improving the overall performance and reliability of the connecting rib 32, and further ensuring the stability and safety of the collecting plate body 31 and the entire battery assembly 100 in the complex operating environment of the vehicle.

[0063] In some embodiments of the present application, the end of the isolation plate 5 is bent so that at least part of the end of the isolation plate 5 overlaps each other.
