Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] The following is for reference. Figures 1-3 A battery pack 100 according to an embodiment of the present utility model is described.

[0028] like Figures 1-3 As shown, the battery pack 100 according to an embodiment of the present utility model includes: a cold plate 10, a battery module 20, a mounting plate 30, an electrical component 40, and a conductive component.

[0029] Along the height direction of battery pack 100 (i.e. Figure 2(As shown in the Z direction), the cold plate 10 is located below the battery module 20, and the mounting plate 30 is located above the battery module 20. The battery module 20 is connected to both the mounting plate 30 and the cold plate 10. At least a portion of the conductive components and the electrical components 40 are located on the mounting plate 30 and on the side of the mounting plate 30 away from the battery module 20.

[0030] Among them, along the height direction of the battery pack 100 (i.e. Figure 2 (As shown in the Z direction), the cold plate 10 is located below the battery module 20, and the mounting plate 30 is located above the battery module 20, that is, along the height direction of the battery pack 100 (i.e., Figure 2 (As shown in the Z direction), the mounting plate 30, battery module 20, and cold plate 10 are arranged sequentially from top to bottom.

[0031] The battery module 20 is connected to both the mounting plate 30 and the cold plate 10. The connection between the battery module 20 and the mounting plate 30 can be, but is not limited to, welding or bolting. In some embodiments of this application, the battery module 20 and the mounting plate 30 are connected by bolts. Similarly, the connection between the battery module 20 and the cold plate 10 can be, but is not limited to, welding or bolting. In some embodiments of this application, the battery module 20 and the cold plate 10 are connected by bolts.

[0032] As some embodiments of this application, the mounting plate 30, battery module 20, and cold plate 10 are fixedly connected by bolts.

[0033] As some embodiments of this application, the battery pack 100 also includes: a housing 60, a mounting plate 30, a battery module 20, and a cold plate 10, all of which are housed in the housing 60.

[0034] As some embodiments of this application, the mounting plate 30, battery module 20, and cold plate 10 are fixedly connected by bolts, and the bolts are fixed to the bottom wall 601 of the housing 60.

[0035] As some embodiments of this application, the cold plate 10 may be configured as a water-cooled plate.

[0036] At least a portion of the conductive components and electrical components 40 are disposed on the mounting plate 30 and located on the side of the mounting plate 30 away from the battery module 20, that is, along the height direction of the battery pack 100 (i.e., Figure 2 (As shown in the Z direction), at least a portion of the conductive element and the electrical component 40 are disposed on the side of the mounting plate 30 away from the battery module 20. In some embodiments of this application, a portion of the conductive element and the electrical component 40 are disposed on the mounting plate 30 and located on the side of the mounting plate 30 away from the battery module 20. In some embodiments of this application, all of the conductive element and the electrical component 40 are disposed on the mounting plate 30 and located on the side of the mounting plate 30 away from the battery module 20.

[0037] It should be noted that the battery pack 100 proposed in this application can provide mounting positions for conductive components and electrical components 40 through the mounting plate 30. At least a portion of the conductive components and the electrical components 40 can be located on the mounting plate 30 and on the side of the mounting plate 30 away from the battery module 20. This reduces the lateral space occupied, increases the safety clearance, and separates the battery module 20 from the area where the electrical components 40 are located, improving safety. Furthermore, due to the increased safety clearance, the structural strength requirements for components such as the housing 60 and the module end plate are reduced. This allows for the selection of materials with relatively weak structural strength (while still meeting safety performance requirements) and relatively low cost to produce components such as the housing 60 and module end plates. This reduces the production cost and weight of the battery pack 100. Furthermore, since at least some of the conductive components and electrical components 40 are located on the mounting plate 30, the side walls of the housing 60 can reduce or even eliminate mounting or constraint structures such as brackets and clips. This reduces the structural complexity of the housing 60 and the requirements for its production and processing, effectively lowering the production and processing costs of the housing 60.

[0038] Furthermore, when assembling the battery pack 100, the mounting plate 30, battery module 20, and cold plate 10 can be assembled first to form an assembly. Then, the assembly can be assembled with other components. Alternatively, the mounting plate 30, battery module 20, and cold plate 10 can be assembled with other components sequentially. This allows for the selection of the battery pack 100 assembly scheme based on actual conditions, greatly improving the production cycle of the battery pack 100, increasing assembly efficiency, and reducing the overall labor time consumption of battery pack 100 assembly. Moreover, by placing the mounting plate 30 above the battery module 20 and the cold plate 10 below the battery module 20, the mounting plate 30 and cold plate 10 can protect the battery module 20, improving the safety of the battery pack 100.

[0039] Therefore, by positioning the mounting plate 30 above the battery module 20, and by placing at least a portion of the conductive components and the electrical components 40 on the mounting plate 30 and located on the side of the mounting plate 30 away from the battery module 20, the lateral space occupied can be reduced, the safety clearance increased, and the longitudinal space utilization rate improved (the longitudinal direction is the height direction of the battery pack 100, i.e., ...). Figure 2 (as shown in the Z direction) Moreover, due to the increased safety clearance, the structural strength requirements for components such as the housing 60 and module end plate can be reduced, which is beneficial to reduce costs and weight. In addition, by placing the mounting plate 30 above the battery module 20, the battery module 20 can be protected by the mounting plate 30, thereby improving the safety of the battery pack 100.

[0040] In some embodiments of this utility model, such as Figure 2As shown, the battery module 20 includes: a plurality of battery cells 201 and a module end plate, along a first direction (i.e. Figure 2 (As shown in the X direction), the module end plate is located on the side of the outermost battery cell 201 away from the other battery cells 201. The module end plate, cold plate 10, and mounting plate 30 together define the receiving space 11. Multiple battery cells 201 are located in the receiving space 11. The first direction (i.e., Figure 2 The X direction shown is perpendicular to the height direction of the battery pack 100 (i.e., the direction of the height of the battery pack 100). Figure 2 The Z direction shown is perpendicular to the direction indicated.

[0041] The number of battery cells 201 can be multiple, including but not limited to two, three, four, etc. As some embodiments of this application, the number of battery cells 201 is twenty. The twenty battery cells 201 are electrically connected together, and multiple battery cells 201 can be charged and discharged simultaneously and in equal amounts to improve the service life of the battery cells 201.

[0042] Along the first direction (i.e.) Figure 2 (as shown in the X direction), the module end plate is located on the side of the outermost battery cell 201 that is away from the other battery cells 201, that is, along the first direction (i.e. Figure 2 (As shown in the X direction), the module end plate is disposed outside the outermost battery cell 201 among multiple battery cells 201. Furthermore, along the first direction (i.e., Figure 2 (As shown in the X direction), both sides have module end plates. The module end plates, cold plate 10, and mounting plate 30 together define the receiving space 11, where multiple battery cells 201 are located. It can be understood that the module end plates, cold plate 10, and mounting plate 30 can be constructed in a "U"-shaped structure to protect the battery module 20. This reduces the structural strength requirements of the module end plates, allowing for the selection of materials with relatively weak structural strength (while still meeting safety performance requirements) and relatively low cost to produce the module end plates, thereby achieving the technical effect of weight reduction and cost reduction.

[0043] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the battery pack 100 also includes: a housing 60 and connectors. At least a portion of the conductive components, the cold plate 10, the battery module 20, the mounting plate 30, and the electrical components 40 are all housed in the housing 60. The connectors are sequentially inserted through the mounting plate 30, the module end plate, and the cold plate 10 and are assembled with the bottom wall 601 of the housing 60.

[0044] As some embodiments of this application, the housing 60 can define a receiving space 61, in which at least a portion of the conductive components, the cold plate 10, the battery module 20, the mounting plate 30, and the electrical components 40 are all housed. This arrangement can protect at least a portion of the conductive components, the cold plate 10, the battery module 20, the mounting plate 30, and the electrical components 40 through the housing 60, thereby improving the reliability and safety of the battery pack 100.

[0045] The connector can be sequentially inserted through the mounting plate 30, the module end plate, and the cold plate 10 and assembled with the bottom wall 601 of the housing 60. As some embodiments of this application, the connector is constructed as a bolt. The mounting plate 30, the module end plate, and the cold plate 10 have mounting holes, and the bottom wall 601 of the housing 60 has threaded holes. The connector can be sequentially inserted through the mounting holes of the mounting plate 30, the module end plate, and the cold plate 10 and assembled with the threaded holes of the bottom wall 601 of the housing 60, so that the mounting plate 30, the module end plate, and the cold plate 10 are fixed to the housing 60.

[0046] As some embodiments of this application, the connector is constructed as a bolt, the mounting plate 30, the module end plate, and the cold plate 10 have mounting holes, and the bottom wall 601 of the housing 60 is provided with a mating nut. The connector can be sequentially inserted into the mounting holes of the mounting plate 30, the module end plate, and the cold plate 10, and be assembled with the mating nut of the bottom wall 601 of the housing 60, so that the mounting plate 30, the module end plate, and the cold plate 10 are fixed to the housing 60.

[0047] It should be noted that when assembling the battery pack 100, the mounting plate 30, battery module 20, and cold plate 10 can be assembled into a single assembly first, and then installed into the housing 60 as a whole. For example, the battery module 20 can be installed on the cold plate 10 first, then the mounting plate 30 can be installed on the battery module 20, and then conductive parts and electrical components 40 can be installed on the mounting plate 30. At the same time, the connector and explosion-proof valve can be installed in the housing 60. Finally, the module end plate is lifted into the housing by hoisting and fixed by the connector.

[0048] Alternatively, the mounting plate 30, battery module 20, and cold plate 10 can be assembled in the housing 60 according to the assembly sequence. For example, the connector and explosion-proof valve can be installed in the housing 60 first, then the cold plate 10 can be installed in the housing 60, then the battery module 20 can be installed in the housing 60, then the mounting plate 30 can be installed in the housing 60, then the mounting plate 30, module end plate, and cold plate 10 can be fixed to the housing 60 by the connectors, and finally the electrical components 40 can be installed.

[0049] Furthermore, since at least some of the conductive components and electrical components 40 are located on the mounting plate 30, the side walls of the enclosure 60 can reduce or even eliminate mounting or constraint structures such as brackets and clips, thereby reducing the structural complexity of the enclosure 60 and the requirements for its production and processing, and effectively reducing the production and processing costs of the enclosure 60.

[0050] This configuration facilitates the assembly of conductive components, cold plate 10, battery module 20, mounting plate 30, and electrical components 40. Furthermore, the enclosure 60 provides protection for these components, reducing the risk of structural damage within the battery pack 100. Additionally, this configuration allows for selection of the battery pack 100 assembly scheme based on actual conditions, improving the overall production cycle time and assembly efficiency of the battery pack 100 while reducing overall assembly time.

[0051] In some embodiments of this utility model, the electrical component 40 includes: a battery management system 41 and / or a battery system distribution box 42.

[0052] As some embodiments of this application, electrical component 40 includes a battery management system 41 (BMS), as some embodiments of this application, electrical component 40 includes a battery system distribution box 42 (BDU), and as some embodiments of this application, electrical component 40 includes a battery management system 41 and a battery system distribution box 42.

[0053] Among them, the battery management system 41 can monitor the status of the battery module 20 (such as voltage, current, temperature, and charge) to ensure the safe and efficient operation of the battery module 20. The battery system distribution box 42 is responsible for the high-voltage circuit management of the battery pack 100, including high-voltage on / off control (such as connecting or disconnecting high-voltage power when the vehicle starts / stops power).

[0054] This arrangement allows for a reasonable design of the battery pack 100 and enables the electrical components 40 to be configured according to actual conditions, which helps improve the reliability of the battery pack 100. Furthermore, it separates the battery module 20 from the electrical components 40, thereby improving safety.

[0055] In some embodiments of this utility model, the conductive element includes: wire harness and / or electrical connector bar.

[0056] In some embodiments of this application, the conductive component includes a wire harness; in some embodiments of this application, the conductive component includes an electrical connector; in some embodiments of this application, the conductive component includes both a wire harness and an electrical connector. Both the wire harness and the electrical connector can be used to electrically connect two components. In some embodiments of this application, the wire harness can be used for electrical connections of low-voltage components, and the electrical connector can be used for electrical connections of high-voltage components. In some embodiments of this application, the electrical connector can be constructed as a copper busbar, which offers high reliability and low cost.

[0057] This arrangement allows at least a portion of the wiring harness and / or at least a portion of the electrical connectors to be located on the mounting plate 30 and on the side of the mounting plate 30 away from the battery module 20, effectively reducing the lateral space occupied, increasing the safety clearance, and reducing the structural strength requirements for components such as the housing 60 and module end plates. This allows for the selection of materials with relatively weak structural strength (while still meeting safety performance requirements) and relatively low cost to produce components such as the housing 60 and module end plates, thereby reducing the production cost and weight of the battery pack 100. In addition, the side walls of the housing 60 can reduce or even eliminate mounting or constraint structures such as brackets and clips, reducing the structural complexity of the housing 60 and the manufacturing requirements of the housing 60, effectively reducing the manufacturing cost of the housing 60.

[0058] In some embodiments of this utility model, along the direction perpendicular to the height of the battery pack 100 (i.e. Figure 2 In the direction of the Z direction shown, the conductive component is located on the side of the mounting plate 30 away from the battery module 20 and is arranged with the electrical components 40.

[0059] Along the direction perpendicular to the height of the battery pack 100 (i.e. Figure 2 The direction shown is the Z direction, that is, along the horizontal direction. The portion of the conductive element located on the side of the mounting plate 30 away from the battery module 20 is arranged with the electrical component 40. In other words, the portion of the conductive element is located on the side of the mounting plate 30 away from the battery module 20, and the portion of the conductive element located on the side of the mounting plate 30 away from the battery module 20 is arranged with the electrical component 40 in the horizontal direction.

[0060] This arrangement allows for a rational internal structure design of the battery pack 100, and enables efficient use of the height of the battery pack 100 (i.e., Figure 2 The space in the Z direction (as shown) can improve the space utilization of the battery pack 100.

[0061] In some embodiments of this utility model, the battery pack 100 further includes a fixing member, which is disposed on the mounting plate 30 and is used to fix the conductive component.

[0062] The fastener can be, but is not limited to, buckles, cable ties, etc. The fastener is located on the mounting plate 30, that is, the fastener is connected to the mounting plate 30. The connection method between the fastener and the mounting plate 30 can be, but is not limited to, welding, bolt connection, snap connection, etc. As some embodiments of this application, the fastener and the mounting plate 30 are connected by welding. The fastener is used to fix the conductive parts on the mounting plate 30.

[0063] This arrangement facilitates the fixing of conductive components on the mounting plate 30, thereby enabling the reasonable arrangement of the positions of conductive components and electrical components 40, making reasonable use of the space in the battery pack 100, and improving the installation firmness of the conductive components on the mounting plate 30, which is beneficial to improving the reliability of the battery pack 100.

[0064] In some embodiments of this utility model, the fixing member includes: a buckle, the buckle having a snap-fit ​​portion for fixing the conductive member.

[0065] Among them, along the height direction of the battery pack 100 (i.e. Figure 2 (As shown in the Z direction), one end of the buckle is fixed to the mounting plate 30, and the other end of the buckle is constructed as a snap-fit ​​part, which is used to fix the conductive component. For example, the snap-fit ​​part is open on the side away from the mounting plate 30 to form a snap-fit ​​groove, which can snap-fit ​​and fix the conductive component. Alternatively, the snap-fit ​​part can define a snap-fit ​​through hole, through which the conductive component can pass and snap-fit.

[0066] By including snap-fit ​​fasteners, the mounting plate 30 can be securely and stably installed and fixed to the conductive components, which improves the ease of fixing the conductive components and the stability of the installation.

[0067] In some embodiments of this utility model, the fixing member includes: a cable tie, the mounting plate 30 has a mating hole, the cable tie passes through the mating hole and binds the conductive member to the fixing member.

[0068] The mounting plate 30 has mating holes, and cable ties can be inserted through the mating holes of the mounting plate 30 to tie the conductive component to the fixing component, so that the conductive component is fixed to the mounting plate 30.

[0069] As some embodiments of this application, the two ends of the cable tie can be respectively inserted into two mating holes to bind the conductive component to the mounting plate 30.

[0070] By including cable ties in the fastener, the conductive component can be bundled to the mounting plate 30, which enables the mounting plate 30 to securely and stably fix the conductive component, thereby improving the convenience of fixing the conductive component and the stability of the installation.

[0071] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the mounting plate 30 has a plurality of bosses 70, the plurality of bosses 70 including at least one first boss 71 and at least one second boss 72, the first boss 71 and the second boss 72 being arranged orthogonally.

[0072] The number of protrusions 70 may be multiple, including but not limited to two or three. In some embodiments of this application, three protrusions 70 are present. In some embodiments of this application, the three protrusions 70 protrude in a direction away from the battery module 20. In some embodiments of this application, the three protrusions 70 protrude in a direction closer to the battery module 20. The multiple protrusions 70 are arranged orthogonally, that is, in a cross-perpendicular arrangement.

[0073] The plurality of bosses 70 include at least one first boss 71 and at least one second boss 72. In some embodiments of this application, the number of bosses 70 is six, including three first bosses 71 and three second bosses 72, with the first bosses 71 and second bosses 72 arranged orthogonally. In some embodiments of this application, the number of bosses 70 is two, including one first boss 71 and one second boss 72, with the first boss 71 and second boss 72 arranged orthogonally.

[0074] By having multiple bosses 70 on the mounting plate 30, the stress can be evenly distributed, which can improve the overall rigidity and deformation resistance of the mounting plate 30 and help improve the structural strength of the battery pack 100.

[0075] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the battery pack 100 also includes: a mating member, a mounting plate 30 having a boss 70 and a mounting hole 74, the boss 70 defining a receiving groove 73 that opens toward the battery module 20, the mating member being connected to the mounting plate 30 and received in the receiving groove 73, the mounting hole 74 corresponding to the mating member, and the mating member, the mounting hole 74, and the electrical component 40 being mated together.

[0076] The mounting plate 30 has a boss 70 and a mounting hole 74. Specifically, the mounting hole 74 is formed on the boss 70 along the height direction of the battery pack 100 (i.e., Figure 2 (As shown in the Z direction), the boss 70 defines a receiving groove 73 that opens toward the battery module 20. The mating part is connected to the mounting plate 30 and is received in the receiving groove 73. The mating part and the mounting plate 30 can be connected by, but are not limited to, welding, riveting, etc. As some embodiments of this application, the mating part and the mounting plate 30 are connected by welding.

[0077] The assembly hole 74 corresponds to the mating part. The mating part, the assembly hole 74, and the electrical component 40 are assembled together. As some embodiments of this application, the electrical component 40 has a mounting through hole. The mounting through hole, the assembly hole 74, and the mating part are correspondingly arranged. The mating part is constructed as a nut, which allows the bolt to be sequentially inserted into the mounting through hole and the assembly hole 74 and threaded into the mating part, so that the electrical component 40 is disposed on the mounting plate 30.

[0078] By defining a receiving groove 73 that opens toward the battery module 20 by the boss 70, and connecting the mating part to the mounting plate 30 and receiving it in the receiving groove 73, the mating part, the mounting hole 74, and the electrical component 40 are assembled together. This allows the mating part to be accommodated in the receiving groove 73 between the battery module 20 and the mounting plate 30, so that the electrical component 40 can be placed on the mounting plate 30. This can reasonably improve the longitudinal space utilization of the battery pack 100, improve the firmness of the mating between the electrical component 40 and the mounting plate 30, and reduce the risk of damage to the battery module 20 by ensuring that the mating part does not come into contact with the battery module 20.

[0079] The vehicle according to this utility model embodiment includes the battery pack 100 of the above embodiment. By placing the mounting plate 30 above the battery module 20, and having at least a portion of the conductive components and the electrical components 40 disposed on the mounting plate 30 and located on the side of the mounting plate 30 away from the battery module 20, the lateral space occupied can be reduced, the safety clearance increased, and the longitudinal space utilization rate improved (the longitudinal direction is the height direction of the battery pack 100, i.e., ...).
