An electrical connection side plate assembly and a battery pack

Abstract

The application provides an electric connector side plate assembly and a battery pack. The electric connector side plate assembly comprises a bottom plate, a plurality of electric connectors and a cover plate, the cover plate is connected with the bottom plate, the plurality of electric connectors are located between the bottom plate and the cover plate, a first gap is formed between one side of the plurality of electric connectors and the bottom plate, and a second gap is formed between the top of the plurality of electric connectors and the cover plate. When there is a size deviation in the length direction, the width direction and the height direction of the electric core, the gap can be adjusted. The size deviation of the electric core in the grouping process can cause grouping failure. The tolerance existing in the grouping of the electric core is absorbed. After the plurality of electric cores are pre-tightened, the external force on the pole is reduced, the risk of tearing of the pole and the body part of the electric core is reduced, thereby protecting the electric core and reducing the risk of damage to the electric core.

Description

An electrical connector side panel assembly and a battery pack Technical Field

[0001] This invention relates to the field of battery technology, and more particularly to an electrical connector side plate assembly and a battery pack. Background Technology

[0002] As the smallest battery unit, the battery cell needs to be modularized for use. In this process, electrical connectors and components that can connect individual cells in series or parallel are crucial. The function of these connectors is to connect individual cells in series (parallel), ensuring that the battery pack forms an electrical connection path, enabling the battery pack to provide electrical energy. However, each cell has some dimensional variation, i.e., manufacturing tolerance. This manufacturing tolerance affects the consistency of the cell assembly, potentially causing uneven stress on some cells during assembly and pre-tensioning, thus affecting the cell's cycle life.

[0003] In the existing technology, most of the electrical connection components for battery cell assembly use non-metallic brackets, and then install metal conductive sheets in the corresponding positions; when battery cells are assembled, the tabs pass through the non-metallic brackets and are attached to the metal conductive sheets, and the battery cells are connected in series and parallel by welding or other methods; or the bus welding method is directly used to weld the battery cell tabs (terminals).

[0004] In existing technologies, when battery cell size tolerances are grouped together, it is easy to cause battery cell tab overlap problems. This is because the non-metallic support and all the metal conductive sheets are on the same plane. When the battery cell size deviates, the position of the non-metallic support slot remains unchanged, which limits the extension length of the battery cell tab. Therefore, when the tab overlaps with the metal conductive sheet, there will be a situation where the lengths are different, which may cause the battery cell tabs to overlap with each other, leading to a short circuit risk. Summary of the Invention

[0005] In order to solve one or more of the above-mentioned technical problems, the present invention provides an electrical connector side plate assembly and a battery pack.

[0006] The technical solution of this invention to solve the above-mentioned technical problems is as follows: An electrical connector side plate assembly includes: a base plate, multiple electrical connectors, and a cover plate. The cover plate is connected to the base plate, and the multiple electrical connectors are located between the base plate and the cover plate. A first gap exists between one side of the multiple electrical connectors and the base plate, and a second gap exists between the top of the multiple electrical connectors and the cover plate. When there are dimensional deviations in the length, width, and height directions of the battery cell, adjustments can be made through these gaps. In the X direction, a first gap is reserved, allowing the electrical connectors to move back and forth appropriately along the X direction. In the Y direction, a second gap also exists, providing space for vertical movement. In the Z direction, the spacing between the hard-pack slots is shortened by bending the flexible connecting components in the electrical connectors. This solves the problem of assembly defects that may be caused by dimensional deviations in the battery cell assembly process. It absorbs the tolerances present in the battery cell assembly. After multiple battery cells are pre-tightened, the external force on the terminals is reduced, reducing the risk of tearing between the terminals and the battery cell body, thereby protecting the battery cells and reducing the risk of battery cell damage.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, an elastic element is provided on the bottom inner wall of the cover plate, and the bottoms of the plurality of electrical connectors abut against the elastic element. The elastic element can absorb the force on the bottom connection and provide soft support.

[0009] Furthermore, the electrical connector includes: a flexible connecting component and a pair of shaped connecting components, with the pair of shaped connecting components correspondingly installed on both sides of the flexible connecting component. Both the flexible connecting component and the pair of shaped connecting components are made of conductive material. The function of the electrical connector is to connect battery cells that need to be grouped together in series or parallel. The electrical connector consists of two parts: a flexible connecting component and shaped connecting components. The flexible connecting component is made of a conductive material with good plasticity, while the shaped connecting components are made of a conductive material with high strength. The two are connected by welding or other methods. The flexible connecting component of the electrical connector can be bent appropriately to provide space for relative movement of the battery cells when applying pre-tightening force. The electrical connector adopts a combination of flexible and rigid components, which provides the strength required for connecting the battery cell terminals into groups and also provides a buffer against the force applied to the terminals when the battery cell pre-tightening force is applied. The battery cell terminals are less prone to deformation during the application of pre-tightening force, reducing the risk of terminal tearing and battery cell damage.

[0010] Furthermore, the shaped connecting component includes a support plate and a first rigid strip slot, the first rigid strip slot having a semi-circular arc structure, and the first rigid strip slot being mounted on the support plate. This facilitates the connection between the shaped connecting component and the battery cell terminal (tab), and the shaped connecting component can be modified according to the battery cell terminal (tab). The support plate improves the stability of the electrical connector.

[0011] Furthermore, the shaped connecting component includes: a rigid post and a second rigid post slot. The second rigid post slot has a semi-circular arc structure and is mounted on the rigid post. The base plate has multiple grooves for mounting the rigid post, and the rigid post is mounted in the grooves. This facilitates the connection between the shaped connecting component and the battery cell electrode (tab). The shaped connecting component can be modified according to the battery cell electrode (tab), and the rigid post reduces the space occupancy of the electrical connector.

[0012] Furthermore, the cover plate is a one-piece molded structure, with multiple first windows in the middle. The other sides of the multiple electrical connectors are installed in the multiple first windows one by one. Since the first windows have a length limitation, the electrical connectors can only move slightly after being inserted into the first windows, thus playing a restrictive role.

[0013] Alternatively, the cover plate can be a split structure composed of multiple first plates, with the first plates spaced apart and a fourth gap between adjacent first plates. A flexible connecting component is correspondingly positioned to each of the first plates, and the shaped connecting component is located within the fourth gap. The first plates engage and limit the flexible connecting component, thus providing a restrictive function.

[0014] Furthermore, the cover plate is connected to a side panel of the battery system housing. One side of the cover plate is connected to the bottom plate, and the other side of the cover plate is connected to the outer side wall of the side panel of the battery system housing. The electrical connector side panel assembly is installed on the outer side of the side panel of the battery system housing. When a single electrical connector malfunctions and needs to be replaced, it is not necessary to disassemble and replace them one by one from the inside of the housing, nor is it necessary to disassemble the entire integrated cover plate. Only the bottom plate in the side panel assembly needs to be removed, the corresponding electrical connector can be taken out, the housing can be opened, and the corresponding battery cell can be disassembled and replaced, thus reducing maintenance costs.

[0015] Furthermore, the cover plate is a split structure composed of multiple second plates. A pair of third windows are provided in the middle of each second plate, and the shaped connecting component is located within one of these third windows. The flexible connecting component abuts against the second plate. The electrical connector side plate assembly is installed on the outer side of the battery system housing side plate. When a single electrical connector malfunctions and needs replacement, it is not necessary to disassemble and replace them one by one from the inside of the housing, nor is it necessary to disassemble the entire integrated cover plate. Only the bottom plate of the side plate assembly needs to be removed, the corresponding electrical connector taken out, and the housing opened to disassemble and replace the corresponding battery cell, thus reducing maintenance costs.

[0016] Furthermore, a sampling plate is provided between the electrical connector and the base plate. The sampling plate is connected to the cover plate, and a sampling nickel sheet is provided on the sampling plate. The sampling nickel sheet abuts against the electrical connector. The sampling nickel sheet overlaps the electrical connector to collect relevant data.

[0017] Furthermore, this invention also provides a battery pack, including an electrical connector side plate assembly as described in any of the above claims. When there are dimensional deviations in the length, width, and height directions of the battery cells, adjustments can be made through gaps. In the X direction, a first gap is reserved, allowing the electrical connector to move back and forth appropriately along the X direction; in the Y direction, a second gap also exists, providing space for its vertical movement; in the Z direction, the spacing between the hard strip slots is shortened by bending the flexible connecting components in the electrical connector. This solves the problem of assembly defects that may be caused by dimensional deviations in the battery cells during assembly. It absorbs the tolerances present in battery cell assembly. After pre-tightening multiple battery cells, the external force on the terminals is reduced, lowering the risk of tearing between the terminals and the battery cell body, thereby protecting the battery cells and reducing the risk of battery cell damage.

[0059] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0060] Example 1

[0061] As shown in Figures 1 to 13, an electrical connector side plate assembly of this embodiment includes: a base plate 100, a plurality of electrical connectors 200, and a cover plate 300. The cover plate 300 is connected to the base plate 100. The plurality of electrical connectors 200 are located between the base plate 100 and the cover plate 300. A first gap 400 is formed between one side of the plurality of electrical connectors 200 and the base plate 100, and a second gap 500 is formed between the top of the plurality of electrical connectors 200 and the cover plate 300. When there are dimensional deviations in the length, width, and height directions of the battery cell, adjustments can be made through these gaps. In the X direction, a first gap is reserved, allowing the electrical connectors to move back and forth appropriately along the X direction. In the Y direction, a second gap also exists, providing space for vertical movement. In the Z direction, the spacing between the hard-pack slots is shortened by bending the flexible connecting components in the electrical connectors. This solves the problem of assembly defects that may be caused by dimensional deviations in the battery cell assembly process. It also absorbs the tolerances present in the battery cell assembly process. After multiple cells are pre-tightened, the external force on the terminals is reduced, and the risk of partial tearing between the terminals and the cell body is reduced, thereby protecting the cells and reducing the risk of cell damage.

[0062] Both the base plate 100 and the cover plate 300 may be, but are not limited to, rectangular. Multiple reinforcing ribs may be provided at the top and bottom of the cover plate 300 and the base plate 100, respectively, to improve the load-bearing capacity of the cover plate. A third gap 600 exists between the base plate 100 and the cover plate 300, and the electrical connector 200 is located within the third gap 600.

[0063] Example 2

[0064] As shown in Figures 1 to 13, based on Embodiment 1, an elastic element 310 is provided on the bottom inner wall of the cover plate 300, and the bottoms of the plurality of electrical connectors 200 abut against the elastic element 310. The elastic element can absorb the force on the bottom connection and provide soft support.

[0065] Furthermore, the elastic element 310 is made of elastic plastic or elastic rubber. Elastic plastic or elastic rubber can absorb the force at the bottom connection and provide soft support, thus reducing costs.

[0066] Example 3

[0067] As shown in Figures 1 to 13, based on Embodiment 1, the electrical connector 200 includes: a flexible connecting component 210 and a pair of shaped connecting components 220. The pair of shaped connecting components 220 are installed one-to-one on both sides of the flexible connecting component 210. The flexible connecting component 210 and the pair of shaped connecting components 220 are made of conductive material. The function of the electrical connector is to connect battery cells that need to be grouped together in series or parallel. The electrical connector consists of two parts: a flexible connecting component and shaped connecting components. The flexible connecting component is made of a conductive material with good plasticity, while the shaped connecting components are made of a conductive material with high strength. The two are connected by welding or other methods. The flexible connecting component of the electrical connector can be bent appropriately to provide space for the relative movement of the battery cells when applying pre-tightening force. The electrical connector adopts a combination of flexible and rigid components, which provides the strength required for connecting the battery cell terminals into groups and also provides a buffer for the force on the terminals when the pre-tightening force is applied. The battery cell terminals are less prone to deformation during the application of pre-tightening force, reducing the risk of tearing of the terminals and the risk of battery cell damage.

[0068] There are no specific requirements for the soft / hard materials of the electrical connectors (materials for the soft connectors / materials for the shaped connectors). As long as they meet the requirements for conductivity and strength of the hard board (materials for the shaped connectors), and the required toughness of the soft board (materials for the soft connectors), they are acceptable. At the same time, the electrical connectors shown in the figure only show a single parallel and multiple series connection method. They can also be designed as multiple parallel and multiple series methods as needed.

[0069] Furthermore, the shaped connecting component 220 includes a support plate 221 and a first rigid strip slot 222. The first rigid strip slot 222 has a semi-circular arc structure and is mounted on the support plate 221. This facilitates the connection between the shaped connecting component and the battery cell terminal (tab). The shaped connecting component can be modified according to the battery cell terminal (tab), and the support plate improves the stability of the electrical connector.

[0070] It should be noted that the shape and connection method of the electrical connectors are not limited to the styles shown in the figure. There are no specific requirements for the shape and connection method of the connection between the battery cell terminal and the electrical connector. The shape can be square or trapezoidal, etc.; the connection method can be physical connection, clamping contact, bolt connection, or welding, etc.

[0071] Example 4

[0072] As shown in Figures 1 to 13, based on Embodiment 1, the cover plate 300 is an integrally formed structure. The cover plate 300 has multiple first windows 330 in its center, and the other sides of the multiple electrical connectors 200 are correspondingly installed in the multiple first windows 330. Because the first windows have a length limitation, the electrical connectors can only move slightly after being inserted into the first window, thus providing a restrictive function.

[0073] The first window 330 may be, but is not limited to, a square or rectangular through hole.

[0074] Furthermore, the top and bottom of the cover plate 300 are respectively provided with a plurality of second fixing holes 320, and the cover plate 300 is connected to the base plate 100 through the plurality of second fixing holes 320. The base plate 100 is attached to the cover plate 300, and the two are fixed through the second fixing holes or fixed to the corresponding position on the battery box. Due to the attachment of the base plate and the cover plate, there is no risk of the electrical connector falling off.

[0075] The top and bottom of the base plate 100 may be provided with a plurality of first fixing holes 110 for connecting with the cover plate 300, but not limited to.

[0076] Furthermore, the base plate 100 and the cover plate 300 are made of insulating materials to prevent the base plate and cover plate from conducting electricity.

[0077] For the electrical connection component side plate component, there is no specific material restriction; any insulating material is acceptable, but a certain strength is required.

[0078] Example 5

[0079] As shown in Figures 14 to 22, as an alternative to Embodiment 3, this embodiment differs from Embodiment 3 in that the shaped connecting component 220 includes: a rigid post 223 and a second rigid post slot 224. The second rigid post slot 224 has a semi-circular arc structure and is installed on the rigid post 223. The base plate 100 has multiple grooves 225 for installing the rigid post 223, and the rigid post 223 is installed in the grooves 225. This facilitates the connection of the shaped connecting component 220 with the battery cell electrode (tab). The shaped connecting component 220 can be modified according to the battery cell electrode (tab), and the rigid post reduces the space occupancy of the electrical connector.

[0080] The rigid posts 223 of the electrical connector 200 are sequentially assembled into the grooves 225 of the base plate 100. Since the grooves 225 have size and shape limitations, the electrical connector 200 can play a longitudinal limiting role after being placed in them.

[0081] The electrical connector 200 consists of a flexible connector 210, a rigid post 220, and a second rigid post slot 224. The flexible connector 210 is made of a conductive material with good plasticity, while the rigid post 220 and the second rigid post slot 224 are made of conductive materials with high strength. The three are connected by welding or other methods. The second rigid post slot 224 can be modified according to the battery cell terminals (tabs).

[0082] Example 6

[0083] As shown in Figures 14 to 22, as an alternative to Embodiment 4, this embodiment differs from Embodiment 4 in that the cover plate 300 is a split structure composed of multiple first plates 340. The multiple first plates 340 are spaced apart, with a fourth gap 350 between adjacent first plates 340. A flexible connecting component 210 is correspondingly disposed with each of the first plates 340, and the shaped connecting component 220 is located within the fourth gap 350. The first plates fasten and limit the flexible connecting component, thereby achieving a restrictive function.

[0084] Since the number of cover plates corresponds to the number of electrical connectors, they can be disassembled individually if maintenance is required in the future.

[0085] Example 7

[0086] As an alternative to Embodiment 6, this embodiment differs from Embodiment 6 in that the cover plate 300 is an integrally formed structure with multiple second windows for installing electrical connectors and multiple grooves for installing rigid posts.

[0087] Example 8

[0088] As shown in Figures 23 to 39, based on Embodiment 1, the cover plate 300 is connected to the battery system housing side plate 700. One side of the cover plate 300 is connected to the bottom plate 100, and the other side of the cover plate 300 is connected to the outer side wall of the battery system housing side plate 700. The electrical connector side plate assembly is installed on the outer side of the battery system housing side plate 700. When a single electrical connector 200 malfunctions and needs to be replaced, it is not necessary to disassemble and replace them one by one from the inside of the housing (battery system housing), nor is it necessary to disassemble the entire integrated cover plate. Only the bottom plate in the side plate assembly (electrical connector side plate assembly) needs to be removed, the corresponding electrical connector can be taken out, the housing can be opened, and the corresponding battery cell can be disassembled and replaced, thus reducing maintenance costs.

[0089] In this embodiment, the base plate may be provided with a plurality of first fixing holes 110, the number of first fixing holes 110 and the second fixing holes 320 being the same and corresponding in position.

[0090] In this embodiment, the electrical connector can be structured such that both ends of the flexible connector are directly connected to a pair of shaped connectors.

[0091] The base plate 100 is attached to the cover plate 300, and the two are fixed in place at the corresponding positions on the side plate 700 of the battery system housing through the first fixing hole 110 and the second fixing hole 320. Due to the attachment of the base plate 100 and the cover plate 300, and the presence of the slot (i.e., both the base plate and the cover plate are U-shaped structures and have a third window), there is no risk of the electrical connector falling off.

[0092] Example 9

[0093] As shown in Figures 23 to 39, as an alternative to Embodiment 6, this embodiment differs from Embodiment 6 in that the cover plate 300 is a split structure composed of multiple second plates 360. A pair of third windows 370 are provided in the middle of each second plate 360, and the shaped connecting component 220 is located within the third window 370. The flexible connecting component 210 abuts against the second plate 360. The electrical connector side plate assembly is installed on the outer side of the battery system housing side plate 700. When a single electrical connector malfunctions and needs replacement, it is not necessary to disassemble and replace them one by one from the inside of the housing, nor is it necessary to disassemble the entire integrated cover plate. Only the bottom plate of the side plate assembly needs to be removed, the corresponding electrical connector taken out, and the housing opened to disassemble and replace the corresponding battery cell, thus reducing maintenance costs.

[0094] The number of cover plates 300 corresponds one-to-one with the number of electrical connectors 200. A partition 390 is provided between a pair of third windows 370.

[0095] The battery system housing side panel 700 has an opening corresponding to a pair of third windows 370.

[0096] After the cover plate 300 passes through the guide post head 380 and is fixed to the side plate 700 of the battery system box, the shape connection part 220 of the electrical connector 200 passes through the two third windows 370 of the cover plate 300 respectively, while the middle soft connection part is restricted by the partition 390 in the middle of the two third windows 370, so that it cannot pass through completely.

[0097] Example 10

[0098] As shown in Figures 23 to 39, based on Embodiment 1, a sampling plate 800 is provided between the electrical connector 200 and the base plate 100. The sampling plate 800 is connected to the cover plate 300, and a sampling nickel sheet 810 is provided on the sampling plate 800. The sampling nickel sheet 810 abuts against the electrical connector 200. The sampling nickel sheet 810 overlaps the electrical connector 200 to collect relevant data.

[0099] The sampling plate 800 is assembled directly below the electrical connector 200 and installed on the back of the cover plate 300 through the mounting hole 820. The sampling nickel sheet 810 is overlapped on the electrical connector 200 to collect relevant data.

[0100] Example 11

[0101] This invention also provides a battery pack, including an electrical connector side plate assembly as described in any of the above claims. When there are dimensional deviations in the length, width, and height directions of the battery cells, adjustments can be made through gaps. In the X direction, a first gap is reserved, allowing the electrical connector to move back and forth appropriately along the X direction; in the Y direction, a second gap also exists, providing space for its vertical movement; in the Z direction, the spacing between the hard strip slots is shortened by bending the flexible connecting components in the electrical connector. This solves the problem of assembly defects that may be caused by dimensional deviations in the battery cells during assembly. It absorbs tolerances present in battery cell assembly. After pre-tightening multiple battery cells, the external force on the terminals is reduced, lowering the risk of tearing between the terminals and the cell body, thereby protecting the cells and reducing the risk of cell damage.

[0102] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0103] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0104] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0105] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium.
