[0012] In some embodiments, the mounting structure includes a first mounting portion and a second mounting portion connected together, the first mounting portion being connected to the inner wall of the cover, and the connecting structure being connected to the second mounting portion.

[0013] In the above technical solution, by dividing the installation structure into two installation parts, the installation structure can be quickly fixed and installed with the cover and the corresponding module (electric control module or communication module), which is beneficial to improving assembly efficiency.

[0014] In some embodiments, the first mounting portion is provided with second mounting portions on opposite sides along a direction parallel to the inner wall of the cover.

[0015] In the above technical solution, by setting second mounting parts on opposite sides of the first mounting part, a symmetrical double-sided mounting structure is formed, which helps to improve the installation stability of the electronic control module and the communication module. In addition, the entire mounting structure extends along the inner wall plane of the cover, reducing the occupation of internal height space, facilitating the layout of the internal structure, and improving assembly convenience.

[0016] In some embodiments, the first mounting portion is welded to the inner wall of the cover.

[0017] In the above technical solution, by directly welding the first mounting part to the inner wall of the cover, not only is a reliable connection between the mounting structure and the outer shell ensured, but the number of fasteners such as bolts and nuts is also reduced, thereby simplifying the overall structure and assembly process, reducing the overall weight, and lowering the cost.

[0018] In some embodiments, there is a gap between the second mounting portion and the inner wall of the cover.

[0019] In the above technical solution, by setting a gap between the second mounting part and the inner wall of the cover, an operating space can be provided for the installation of the connecting structure, thereby improving the ease of assembly.

[0020] In some embodiments, the connection structure includes a riveting stud, which is riveted to the second mounting portion.

[0021] In the above technical solution, the riveting studs are firmly integrated into the installation structure by using the riveting process. During the disassembly and assembly process, there is no need to clamp the riveting studs. The replacement or maintenance of the corresponding modules can be completed by simply turning the matching nuts, which improves the ease of operation.

[0025] In the above technical solution, by setting the installation structure as an insulating structure, the contact between the corresponding module and the cover (usually made of metal) can be separated, thereby improving the insulation performance and operational reliability of the electronic control device.

[0026] In some embodiments, the mounting structure is a one-piece molded structure.

[0028] In some embodiments, the electronic control device includes a connection structure, and at least one of the electronic control module and the communication module is connected to the inner wall of the cover through the connection structure.

[0029] In the above technical solution, the electronic control module and the communication module are directly fixed to the inner wall of the cover through the connection structure, which eliminates the need for an intermediate installation structure, further simplifies the overall structure and assembly process, reduces the accumulation of assembly tolerances, reduces the occupation of internal space, reduces the overall weight, and lowers the cost.

[0034] In some embodiments, the battery device further includes a housing, with individual battery cells disposed inside the housing and electronic control devices disposed outside or inside the housing.

[0035] In the above technical solutions, when the electronic control device is located outside the enclosure, it avoids occupying internal space, allowing for a higher density arrangement of battery cells, increasing the volumetric energy density of the battery pack, and facilitating the installation, maintenance, or replacement of the electronic control device. When the electronic control device is located inside the enclosure, it improves the integration of the battery pack, protects the electronic control device, and shortens the electrical connection path between the electronic control device and the battery cells, thereby improving electrical reliability.

[0036] Secondly, embodiments of this application provide an electronic control device, including a housing, an electronic control module, a communication module, an electrical connector, and a fixing structure. The housing includes a shell and a cover, with the cover covering the shell to enclose and form an accommodating space.

[0059] Reference Figure 2 As shown, the battery device mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells 102, which are connected in series, parallel, or mixed connections via a busbar.

[0060] In some embodiments, the battery cell assembly is typically formed by arranging a plurality of battery cells 102.

[0061] As an example, the battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells 102 into an independent module. As an example, the battery module can be formed by bundling multiple battery cells 102 together with cable ties.

[0062] In some embodiments, the battery device may be a battery pack, which includes a housing 101 and one or more battery cell assemblies housed in the housing 101.

[0063] As an example, the battery cell assembly can be a battery module, and the battery cell assembly can be housed in the housing 101 by fixing the battery module in the housing 101.

[0064] As an example, the battery cell assembly can also be housed in the housing 101 by directly fixing multiple battery cells 102 to the housing 101.

[0065] As an example, the housing 101 may include a first housing 1011 and a second housing 1012. The first housing 1011 and the second housing 1012 are fastened together to form a closed space inside the housing 101 to house the battery cell assembly. Here, "closed" refers to covering or closing, which can be sealed or unsealed. The first housing 1011 may be a top cover or a bottom plate.

[0066] As an example, the housing 101 may include a top cover, a frame, and a bottom plate. The top cover and the bottom plate are respectively connected to the frame, so that the interior of the housing 101 forms an enclosed space to accommodate the battery cell assembly.

[0067] In some embodiments, the housing 101 may be part of the chassis structure of the vehicle 1000. For example, a portion of the housing 101 may be at least a portion of the floor of the vehicle 1000, or a portion of the housing 101 may be at least a portion of the crossbeams and longitudinal beams of the vehicle 1000.

[0068] In this embodiment, the battery cell 102 can be a secondary battery, which refers to a battery cell that can be recharged after discharge to activate the active materials and continue to be used. The battery cell 102 can be flat, cuboid, or other shapes.

[0069] The battery cell 102 can be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited to this.

[0070] In some embodiments, refer to Figures 2 to 6 , Figure 12 As shown in the figure, this application provides a battery device 100, including a battery cell 102 and an electronic control device 103. The electronic control device 103 includes a housing 1031, an electronic control module 10321, a communication module 10322, an electrical connector, and a fixing structure 1037. The housing 1031 includes a shell 10311 and a cover 10312. The cover 10312 covers the shell 10311 to form an accommodating space 10313. The electronic control module 10321 and the communication module 10322 are disposed within the accommodating space 10313, with the communication module 10322 located on the inner wall of the cover 10312. The electrical connector includes a wiring harness 1034. The electronic control module 10321 is electrically connected to the communication module 10322 and the battery cell 102 respectively through the wiring harness 1034. At least one of the inner walls of the shell 10311 and the inner walls of the cover 10312 is provided with a fixing structure 1037, which is used to fix the wiring harness 1034.

[0071] A battery cell 102 refers to the smallest unit that makes up the battery device 100, used for outputting or inputting electrical energy. Multiple battery cells 102 can be arranged side-by-side to form a battery cell assembly. For example, such as... Figure 2 As shown, in the battery cell assembly, the large surfaces (the surfaces with the largest area) of two adjacent battery cells 102 are arranged close to each other.

[0072] In the electronic control device 103, its cover 10312 covers the housing 10311, forming a closed accommodating space 10313 between the two, which is used to accommodate and protect the internal electronic control module 10321, communication module 10322 and other structures.

[0073] As an example, such as Figure 3 , Figure 5 and Figure 6As shown, the top of the housing 10311 has an opening, and the edge of the opening is provided with an outwardly bent flange 10314. Multiple first fastening holes 10315 are arranged around the flange 10314. Multiple second fastening holes 10316 are provided on the edge of the cover 10312. The second fastening holes 10316 and the first fastening holes 10315 are arranged in a one-to-one correspondence. The cover 10312 covers the flange 10314 to close the top opening. Fasteners 1033 such as bolts, screws, and pins can be inserted into the second fastening holes 10316 and the first fastening holes 10315 to achieve detachable assembly of the cover 10312 and the housing 10311.

[0074] As an example, a sealing ring is provided between the flange 10314 of the cover 10312 and the housing 10311 to improve the connection sealing.

[0075] As an example, the electronic control module 10321 may be a battery management module (BMU), which can be electrically connected to the controller 200 of the vehicle 1000 via the communication module 10322, and can be electrically connected to the battery cell 102 via electrical connectors such as wiring harness 1034 and connectors.

[0076] In some embodiments, refer to Figure 12 As shown, the electrical connector may include a wiring harness 1034 and a connector. The connector may include a first connector 1038 and a second connector that are adapted to each other. One of the first connector 1038 and the second connector is a plug, and the other is a socket. The first connector 1038 may be disposed on the side wall of the housing 10311, and the second connector may be disposed on the casing 101 of the battery device 100 and electrically connected to the battery cell 102. The electronic control module 10321 can be connected to the first connector 1038 through the wiring harness 1034. The second connector can be connected to the first connector 1038 through another wiring harness 1034, thereby realizing the electrical connection between the battery cell 102 and the electronic control module 10321.

[0077] In some embodiments, the communication module is typically installed on the bottom or side wall of the housing. During assembly, it needs to be inserted into the confined space of the housing, making it susceptible to obstruction by other structures and inconvenient to operate. Therefore, in this embodiment, the communication module 10322 is installed on the side of the cover 10312 facing the internal accommodating space 10313 (i.e., the inner wall). The cover 10312 is in an open state before assembly, providing a wide operating surface, avoiding operation in confined spaces, reducing structural obstruction during assembly, and lowering the difficulty of operation, thereby improving the assembly efficiency of the communication module 10322. Furthermore, if the communication module 10322 needs to be replaced or repaired, opening the cover 10312 allows access to the communication module 10322 installed on the inner wall of the cover 10312, making maintenance convenient.

[0078] Therefore, in the embodiments of the present application, by mounting the communication module 10322 in the electric control device 103 on the inner wall of the cover body 10312 and using the cover body 10312 as the mounting platform, the space utilization inside the electric control device 103 is optimized, the operating space of the communication module 10322 during assembly is improved, which is beneficial to improving the assembly efficiency.

[0079] In some embodiments, the fixing structure 1037 can be fixed to the inner wall of the housing 10311 and / or the cover body 10312 by means of welding, screw connection, bonding or the like, and is configured to limit the displacement and shaking of the internal wire harness 1034. Optionally, the fixing structure 1037 can be a wire clip, an adhesive tape or other structures.

[0080] By way of example, as shown in Figure 5 and Figure 9 the fixing structure 1037 may include a main body portion 10371 and fixing portions 10372. Fixing portions 10372 are respectively disposed on both sides of the main body portion 10371, and the fixing portions 10372 can be fixed to the inner wall of the housing 10311 and / or the cover body 10312 by means of screw connection, welding or the like. A wire pressing passage is formed between the main body portion 10371 and the inner wall where the main body portion 10371 is located, the wire harness 1034 passes through the wire pressing passage, and the wire pressing passage is pressed against the wire harness 1034.

[0081] By way of example, as shown in Figure 5 and Figure 9 the fixing structure 1037 is an integrally formed structure.

[0082] By way of example, as shown in Figure 5 and Figure 9 the shape of the fixing structure 1037 is substantially n-shaped.

[0083] Therefore, in the embodiments of the present application, the fixing structure 1037 is disposed on the inner wall of the housing 1031, which can fix and constrain the wire harness 1034, reducing the risk of shaking and displacement of the wire harness 1034 under working conditions such as vibration and impact, thereby improving the reliability of electrical connection. In addition, by mounting the communication module 10322 on the inner wall of the cover body 10312, the interference between the communication module 10322 and the wire harness 1034 in the accommodating space 10313 can be reduced, and the risk of abrasion of the wire harness 1034 is lowered, thereby improving the reliability.

[0084] In some embodiments, as shown in Figure 5 the main body portion 10371 of the fixing structure 1037 is provided with a through hole 10373, and the fixing structure 1037 further includes a cable tie. The cable tie passes through the through hole 10373 and binds the wire harness 1034 on the main body portion 10371, further improving the mounting stability of the wire harness 1034.

[0085] In some embodiments, referring to Figure 4 and Figure 8 As shown, the electronic control module 10321 includes an electronic control board located on the inner wall of the cover 10312 and electrically connected to the communication module 10322 and the battery cell 102 via a wiring harness 1034.

[0086] This embodiment of the application improves the operating space of the electronic control board during the assembly process by placing the electronic control board in the electronic control device 103 on the inner wall of the cover 10312, thereby further improving the assembly efficiency of the battery device 100. Furthermore, by mounting the electronic control board on the inner wall of the cover 10312, interference between it and the wiring harness 1034 within the accommodating space 10313 can be reduced, lowering the risk of wear on the wiring harness 1034 and thus improving reliability.

[0087] In some embodiments, refer to Figure 4 As shown, an electronic control module 10321 and a communication module 10322 are arranged on the inner wall of the cover 10312.

[0088] In some embodiments, refer to Figure 8 As shown, the electronic control device 103 includes an installation structure 1035 and a connection structure 1036. The installation structure 1035 is located on the inner wall of the cover 10312, and the electronic control board is connected to the installation structure 1035 through the connection structure 1036.

[0089] Mounting structure 1035 is used to provide a stable mounting platform for the electronic control board. Optionally, the structural form of mounting structure 1035 includes, but is not limited to, mounting bosses, mounting grooves, mounting plates, mounting brackets, etc.

[0090] The connecting structure 1036 is used to connect and fix the electronic control board to the mounting structure 1035. Optionally, the connecting structure 1036 may include bolts, screws, magnetic assemblies, etc. The magnetic assemblies include a first component and a second component that magnetically engage with each other. The first component is disposed on the inner wall of the cover 10312 or embedded in the cover 10312, and the second component is disposed on the electronic control board. The first component and the second component can be mutually magnetic magnets, or one can be a magnet and the other a magnetic metal part (such as a steel sheet).

[0091] In this embodiment of the application, an installation structure 1035 is provided on the inner wall of the cover 10312 of the electronic control device 103, and the electronic control board is detachably fixed to the installation structure 1035 by the connecting structure 1036, which further improves the convenience of assembly and maintenance.

[0092] In some embodiments, refer to Figures 5 to 7 As shown, the electronic control device 103 includes an installation structure 1035 and a connection structure 1036. The installation structure 1035 is located on the inner wall of the cover 10312, and the communication module 10322 is connected to the installation structure 1035 through the connection structure 1036.

[0093] In this embodiment, the communication module 10322 can be detachably fixed to the mounting structure 1035 by using the connection structure 1036, which further improves the convenience of assembly and maintenance.

[0094] In addition, a suitable mounting structure 1035 can be provided on the inner wall of the cover 10312 according to the size and weight of the electrical module, thereby improving adaptability.

[0095] As an example, such as Figure 7 As shown, when installing a smaller and lighter communication module 10322, the mounting structure 1035 can be a smaller and thinner mounting plate.

[0096] As an example, such as Figure 8 As shown, when installing a larger and heavier electronic control module 10321, the mounting structure 1035 can be a larger and thicker mounting plate.

[0097] In some embodiments, refer to Figures 5 to 8 As shown, the mounting structure 1035 includes a first mounting part 10351 and a second mounting part 10352 connected together. The first mounting part 10351 is connected to the inner wall of the cover 10312, and the connecting structure 1036 is connected to the second mounting part 10352.

[0098] The first mounting part 10351 can be connected and fixed to the inner wall of the cover 10312 by welding, screws, or other methods, serving as structural support and positioning reference to ensure the stability of the entire mounting structure 1035 on the cover 10312. The second mounting part 10352 is used to connect and fix the electronic control module 10321 or the communication module 10322.

[0099] As an example, the first mounting part 10351 and the second mounting part 10352 may be plate-shaped structures.

[0100] This embodiment of the application divides the mounting structure 1035 into two mounting parts, which can realize the rapid fixed installation of the mounting structure 1035 with the cover 10312 and the corresponding module, thereby improving assembly efficiency.

[0101] In some embodiments, refer to Figures 5 to 8 As shown, the first mounting part 10351 has a second mounting part 10352 on each of its opposite sides along the direction parallel to the inner wall of the cover 10312.

[0102] The direction parallel to the inner wall of the cover 10312 includes the length direction X and the width direction of the cover 10312. As an example, the second mounting parts 10352 are arranged in pairs on the left and right sides of the first mounting part 10351 along the length direction X of the cover 10312, forming a transversely symmetrical double-sided mounting structure. The electronic control module 10321 or the communication module 10322 can be fixed across the second mounting parts 10352 on both sides to form a double-sided fixation, which is beneficial to improving the installation stability.

[0103] In addition, the entire mounting structure 1035 extends along the inner wall plane of the cover 10312, reducing the occupation of internal height space, facilitating the layout of the internal structure, and improving assembly convenience.

[0104] In some embodiments, refer to Figure 5 As shown, the first mounting part 10351 is welded to the inner wall of the cover 10312.

[0105] In this embodiment of the application, by directly welding the first mounting part 10351 to the inner wall of the cover 10312, not only is a reliable connection between the mounting structure 1035 and the outer shell 1031 ensured, but the number of fasteners such as bolts and nuts is also reduced, thereby simplifying the overall structure and assembly process, reducing the overall weight, and lowering the cost.

[0106] In some embodiments, refer to Figure 7 As shown, there is a gap 10353 between the second mounting part 10352 and the inner wall of the cover 10312. The height of the gap 10353 can be flexibly designed according to the specific type of the connection structure 1036, for example, 1~5mm.

[0107] In this embodiment of the application, by setting a gap 10353 between the second mounting part 10352 and the inner wall of the cover 10312, an operating space can be provided for the installation of the connecting structure 1036, thereby improving the ease of assembly.

[0108] In some embodiments, refer to Figure 5 As shown, the mounting structure 1035 is a mounting plate, and the shape of the mounting plate is roughly Z-shaped.

[0109] In some embodiments, refer to Figures 5 to 8 As shown, the connection structure 1036 includes a riveting stud 10361, which is riveted to the second mounting part 10352.

[0110] The riveting stud 10361 includes pull riveting studs, press riveting studs, etc., which can be riveted to the second mounting parts 10352 on both sides of the mounting structure 1035 to achieve a fixed connection.

[0111] The connection structure 1036 may also include a nut 10362, which is connected to the riveting stud 10361. As an example, such as... Figure 7 and Figure 8 As shown, the four corners of the electronic control module 10321 and the communication module 10322 are respectively provided with connecting parts 10323. The connecting parts 10323 are provided with connecting holes, which match the riveting studs 10361 to facilitate quick alignment and insertion, and are locked and fixed by nuts 10362.

[0112] For example, when assembling the communication module 10322, the riveting stud 10361 is riveted to the second mounting part 10352, and then the first mounting part 10351 is welded to the inner wall of the cover 10312 to form an integral mounting structure. Then the communication module 10322 is placed in place, its connection hole is fitted into the riveting stud 10361, and then the nut 10362 is tightened to complete the fixation.

[0113] In this embodiment, the riveting stud 10361 is firmly integrated into the mounting structure 1035 by using a riveting process. During the disassembly and assembly process, there is no need to clamp the riveting stud 10361. The replacement or maintenance of the corresponding module can be completed by simply turning the matching nut 10362, which improves the ease of operation.

[0114] In some embodiments, refer to Figure 7 and Figure 8 As shown, the orthographic projection of the mounting structure 1035 on the inner wall of the cover 10312 includes the orthographic projection of the module mounted on the mounting structure 1035 on the inner wall of the cover 10312.

[0115] Here, "orthographically included" means that when projected from a direction perpendicular to the inner wall of the cover 10312 (the height direction Y of the housing 10311) onto the inner wall of the cover 10312, the projected outline of the mounting structure 1035 completely covers or surrounds the projected outline of the module mounted on the mounting structure 1035. The module mounted on the mounting structure 1035 refers to the electronic control module 10321 or the communication module 10322.

[0116] This design achieves a surrounding fixation of the electronic control module 10321 or the communication module 10322, suppressing the risk of overturning under vibration, impact and other working conditions, and improving the stability and reliability of the installation.

[0117] In some embodiments, the mounting structure 1035 is an insulating structure.

[0118] Optionally, the mounting structure 1035 can be made of engineering plastics such as polyamide, polybutylene terephthalate, or polyphenylene sulfide. Alternatively, the mounting structure 1035 includes a metal body and an insulating layer, with the insulating layer covering the entire outer surface of the metal body. The metal body can be made of materials such as stainless steel or aluminum alloy. The insulating layer can be made of materials such as epoxy resin or polyimide.

[0119] In this embodiment of the application, by setting the mounting structure 1035 as an insulating structure, the contact between the corresponding module and the cover 10312 (usually made of metal) can be separated, thereby improving the insulation performance and operational reliability of the electronic control device 103.

[0120] In some embodiments, refer to Figure 5 As shown, the mounting structure 1035 is a one-piece molded structure.

[0121] Optionally, the mounting structure 1035 can be integrally formed using processes such as injection molding, stamping, and bending.

[0122] This application embodiment simplifies the manufacturing and assembly process and improves the overall structural integrity by setting the mounting structure 1035 as an integrally molded structure.

[0123] In some embodiments, refer to Figures 9 to 11 As shown, the electronic control device 103 includes a connection structure 1036, and at least one of the electronic control module 10321 and the communication module 10322 is connected to the inner wall of the cover 10312 through the connection structure 1036.

[0124] The electronic control module 10321 and communication module 10322 of this application embodiment can be directly fixed to the inner wall of the cover 10312 through the connection structure 1036, which can eliminate the intermediate installation structure, further simplify the overall structure and assembly process, reduce the accumulation of assembly tolerances, reduce the occupation of internal space, reduce the overall weight, and reduce costs.

[0125] In some embodiments, refer to Figure 9 and Figure 11 As shown, the connecting structure 1036 includes a riveting stud 10361, which is riveted to the inner wall of the cover 10312.

[0126] As an example, such as Figure 11 As shown, the communication module 10322 has a connecting part 10323 at each of its four corners. The connecting part 10323 has a connecting hole that matches the riveting stud 10361, which facilitates quick alignment and insertion, and is locked in place by the nut 10362.

[0127] When assembling the communication module 10322, the riveting stud 10361 is riveted to the inner wall of the cover 10312, and then the communication module 10322 is placed in place so that its connection hole fits into the riveting stud 10361, and then the nut 10362 is tightened to complete the fixation.

[0128] In this embodiment, the riveting stud 10361 is firmly integrated into the inner wall of the cover 10312 by using a riveting process. During the disassembly and assembly process, there is no need to clamp the riveting stud 10361. The replacement or maintenance of the corresponding module can be completed by turning the matching nut 10362, which improves the convenience of operation.

[0129] In some embodiments, the housing 10311 and / or the cover 10312 are structural components formed by stamping steel plates.

[0130] As an example, steel sheets may include cold-rolled steel sheets, galvanized steel sheets, etc.

[0131] The housing 10311 and / or cover 10312 of this application embodiment are formed by stamping steel plate, which is simple and can improve the overall structural strength of the housing 1031 of the electronic control device, thereby improving reliability.

[0132] In some embodiments, the wall thickness of the steel plate is 0.8~1.2mm.

[0133] As an example, the steel plate wall thickness of housing 10311 can be 1 mm.

[0134] As an example, the steel plate wall thickness of the cover 10312 can be 1.2 mm.

[0135] If the steel plate wall thickness is less than 0.8 mm, the steel plate structure will lack sufficient strength, posing a risk of deformation and thus affecting reliability; if the steel plate wall thickness is greater than 1.2 mm, the stamping and forming difficulty of the steel plate structure will increase. Therefore, in the embodiments of this application, the shell 10311 and / or cover 10312 are formed by stamping steel plates with a wall thickness of 0.8~1.2 mm, which can reduce the difficulty of stamping and forming while ensuring structural strength.

[0136] In some embodiments, refer to Figure 2 As shown, the battery device 100 also includes a housing 101, with battery cells 102 disposed inside the housing 101, and an electronic control device 103 disposed outside or inside the housing 101.

[0137] When the electronic control device 103 is located outside the housing 101, it avoids occupying internal space, allowing the battery cells 102 to be arranged at a higher density, thus increasing the volumetric energy density of the battery device 100 and facilitating the installation, maintenance, or replacement of the electronic control device 103. When the electronic control device 103 is located inside the housing 101, it increases the integration of the battery device 100, protects the electronic control device 103, and shortens the electrical connection path between the electronic control device 103 and the battery cells 102, thereby improving electrical reliability.

[0138] In some embodiments, refer to Figure 3 and Figure 4 As shown, this application embodiment provides an electronic control device 103, including a housing 1031, an electronic control module 10321, a communication module 10322, an electrical connector, and a fixing structure 1037. The housing 1031 includes a shell 10311 and a cover 10312. The cover 10312 covers the shell 10311 to form an accommodating space 10313. The electronic control module 10321 and the communication module 10322 are disposed within the accommodating space 10313, and the communication module 10322 is located on the inner wall of the cover 10312. The electrical connector includes a wiring harness 1034. The electronic control module 10321 is electrically connected to the communication module 10322 and the battery cell 102 respectively through the wiring harness 1034. At least one of the inner walls of the shell 10311 and the inner walls of the cover 10312 is provided with a fixing structure 1037, which is used to fix the wiring harness 1034.

[0139] In this embodiment, by placing the communication module 10322 in the electronic control device 103 on the inner wall of the cover 10312, the cover 10312 serves as an installation platform, providing a wide operating surface, avoiding work in confined spaces, reducing structural obstruction during assembly, improving the operating space for the communication module 10322 during assembly, reducing operational difficulty, and thus improving assembly efficiency. By providing a fixing structure 1037 on the inner wall of the outer casing 1031, the wiring harness 1034 can be fixed and constrained, reducing the risk of shaking and displacement of the wiring harness 1034 under vibration, impact, and other conditions, thereby improving the reliability of the electrical connection. Furthermore, by installing the communication module 10322 on the inner wall of the cover 10312, interference between it and the wiring harness 1034 within the accommodating space 10313 can be reduced, lowering the risk of wear on the wiring harness 1034, thereby improving reliability.

The electronic control device 103 is disposed outside the housing 101 and includes a housing 1031, an electronic control module 10321, and a communication module 10322. The housing 1031 includes a shell 10311 and a cover 10312. The cover 10312 covers the shell 10311 to enclose an accommodating space 10313 inside the shell 1031. The sidewall of the shell 10311 is provided with a plurality of first connectors 1038. The electronic control module 10321 and the communication module 10322... 22 is disposed within the accommodating space 10313. The communication module 10322 is fixedly installed on the inner wall of the cover 10312. The communication module 10322 is electrically connected to the electronic control module 10321 via the wiring harness 1034, and is also electrically connected to the first connector 1038 via the wiring harness 1034. The first connector 1038 can be electrically connected to a connector adapted on the controller 200 of the vehicle 1000. The electronic control module 10321 is electrically connected to another first connector 1038 via the wiring harness 1034. The first connector 1038 can be electrically connected to a second connector via the wiring harness 1034, thereby realizing the electrical connection between the electronic control module 10321 and the battery cell 102.
