[0002] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important part of the sustainable development of the automotive industry.

[0003] Electric vehicles typically incorporate multiple electronic control modules to coordinate vehicle operation. Currently, some vehicles integrate these modules into a single housing to reduce space requirements. However, this design often results in significant electromagnetic interference between the modules, particularly between high- and low-voltage modules, potentially impacting vehicle safety. Utility Model Content

[0004] The purpose of this application is to provide an electrical structure, chassis, and vehicle to improve the problem of strong electromagnetic interference between high and low voltage modules in electrical structures that integrate multiple electronic control modules in related technologies.

[0005] In a first aspect, embodiments of this application provide an electrical structure, including a housing and an electronic control module;

[0006] The outer shell has a containment space, which has a high-pressure area and a low-pressure area, and the high-pressure area and the low-pressure area are isolated from each other.

[0007] The electrical control module includes a high-voltage module and a low-voltage module. The high-voltage module is installed in the high-voltage area, and the low-voltage module is installed in the low-voltage area.

[0008] In the technical solution of this application embodiment, by separating a high-voltage area and a low-voltage area in the housing, the high-voltage module of the electronic control module is installed in the high-voltage area, and the low-voltage module of the electronic control module is installed in the low-voltage area, while the high-voltage area and the low-voltage area are isolated, thereby isolating the high-voltage module and the low-voltage module to reduce electromagnetic interference between the high-voltage module and the low-voltage module, so that the vehicle using this electrical structure can operate well.

[0009] In some embodiments, the electrical structure includes a high-voltage box, which is installed in a housing space, and a high-voltage area is formed inside the high-voltage box, with a high-voltage module installed in the high-voltage box.

[0010] By using the above technical solution, a high-voltage box can be set up to easily separate a high-voltage area in the housing space to accommodate the high-voltage module. It can also provide good protection for the high-voltage module. Furthermore, during assembly, the high-voltage module can be assembled separately in the high-voltage box and then installed in the outer casing for easy assembly.

[0011] In some embodiments, the low-voltage module is mounted on the top surface of the high-voltage box.

[0012] By using the above technical solution, the low-voltage module is installed on the top surface of the high-voltage box, which can support the low-voltage module, making assembly easier and reducing the space occupied.

[0013] In some embodiments, the bottom of the high-voltage box is provided with a first conductive busbar, which is electrically connected to the high-voltage module. The bottom of the high-voltage box is provided with a heat-conducting layer, which covers the first conductive busbar and is connected to the bottom of the outer casing.

[0014] The above technical solution involves setting up a first conductive busbar to connect to power supplies such as battery devices, thereby controlling the distribution and use of electrical energy. By placing the first conductive busbar at the bottom of the high-voltage box and providing a heat-conducting layer to cover it, the heat from the first conductive busbar can be effectively conducted to the bottom of the casing, thus effectively dissipating heat from the first conductive busbar. Especially when electrical devices are mounted on the battery device, the battery device's temperature control module can be used to dissipate heat from the bottom of the casing, thereby dissipating heat from the first conductive busbar, allowing it to withstand larger currents.

[0015] In some embodiments, an insulating layer is provided between the thermally conductive layer and the bottom of the housing.

[0016] By using the above technical solution, an insulating layer can be set up to provide good insulation and isolation, so that the first conductive busbar can conduct electrical energy well.

[0019] In some embodiments, the electrical structure further includes a wire harness bracket on which the control wire harness is mounted.

[0020] By using the above technical solution, the wiring harness bracket can provide good support for the control wiring harness. In addition, the wiring harness bracket can also separate the high-voltage module from the low-voltage module, reducing electromagnetic interference between the high-voltage module and the low-voltage module.

[0021] In some embodiments, the control harness is secured to the harness bracket by cable ties.

[0025] In some embodiments, the electrical structure includes a low-voltage box, which is installed in a housing space, and a low-voltage area is formed inside the low-voltage box, with a low-voltage module installed in the low-voltage box.

[0026] By using the above technical solution, a low-voltage box can be set up to easily separate a low-voltage area in the housing space to accommodate the low-voltage module. It can also provide good protection for the low-voltage module. Furthermore, during assembly, the low-voltage module can be assembled separately in the low-voltage box and then installed in the outer casing for easy assembly.

[0027] In some embodiments, the housing has a conductive layer, and the low-voltage box has a conductive structure on at least one side away from the high-voltage box, the conductive structure being electrically connected to the conductive layer.

[0028] Through the above technical solution, a conductive layer is provided on the outer casing, and a conductive structure is provided on the side of the low-voltage box away from the high-voltage box, so that the conductive structure is electrically connected to the conductive layer. This allows the electromagnetic waves received by the low-voltage module to be connected to the conductive layer of the outer casing to form a current loop, which is then conducted to the ground during application, thereby greatly reducing the interference of electromagnetic waves on the low-voltage module signal.

[0029] In some embodiments, the conductive structure includes a conductive buffer layer disposed on a low-voltage box.

[0030] By using the above technical solution, a conductive buffer layer is set up, which not only facilitates the connection between the low-voltage box and the conductive layer of the outer shell, but also provides a buffer protection for the low-voltage box, thereby reducing the impact of external shocks on the low-voltage box and its internal low-voltage modules.

[0031] In some embodiments, the low-voltage box is made of a conductive material.

[0039] In some embodiments, the high-voltage module includes high-voltage devices constituting a high-voltage functional circuit, and the high-voltage devices are located in the high-voltage region.

[0040] By using the above technical solution, placing the high-voltage components of the high-voltage module in the high-voltage area can not only reduce the electromagnetic influence of the high-voltage components on the low-voltage module, but also facilitate heat dissipation of the high-voltage components.

[0041] In some embodiments, the high-voltage functional circuit includes one or more of the following: a boost fast charging circuit, a charging circuit, a discharging circuit, a battery power distribution unit, a power distribution unit, an on-board charger, a DC-DC converter, and an intelligent chassis domain control platform product.

[0043] In some embodiments, a 12V lithium power supply is also installed in the housing.

[0044] The above technical solution allows a 12V lithium power supply to be integrated into the electrical structure to provide 12V DC power to the vehicle.

[0079] Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions.

[0080] Unless otherwise specified, all technical features and optional technical features of this application may be combined to form new technical solutions.

[0081] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

N If one of the C components, such as C2, is closer to the B component than the other C components, then B is adjacent to C2, or C2 is adjacent to B.

[0087] Electric vehicles are vehicles that are driven by an electric motor. Electric vehicles can be purely electric vehicles or hybrid vehicles that combine electric and motor-driven power.

[0088] Electric vehicles typically include a battery pack and a motor. The battery pack powers the motor, enabling the vehicle to operate. Electric vehicles often also include multiple electronic control modules to coordinate vehicle operation. These may include a battery distribution unit to control the power supply from the battery pack to the motor and other components; a battery management unit to monitor the charging and discharging of individual battery cells to ensure their safe operation; and an onboard charger to charge the battery pack.

[0089] Currently, to improve integration, multiple electronic control modules are often integrated into the same housing to reduce space occupation. However, these electronic control modules include both high-voltage and low-voltage modules. High-voltage modules operate with large current and voltage, generating strong electromagnetic interference; while low-voltage modules require smaller current and voltage and are more susceptible to external electromagnetic interference. Therefore, in current electrical structures that integrate multiple electronic control modules, there is often strong electromagnetic interference between the modules, especially between high-voltage and low-voltage modules, which affects the safe use of the vehicle.

[0090] Based on the above considerations, in order to improve the problem of strong electromagnetic interference between high-voltage and low-voltage modules in electrical structures integrating multiple electronic control modules in related technologies, embodiments of this application provide an electrical structure that separates a high-voltage area and a low-voltage area in the housing, installs the high-voltage module of the electronic control module in the high-voltage area, and installs the low-voltage module of the electronic control module in the low-voltage area, and isolates the high-voltage area from the low-voltage area, thereby reducing electromagnetic interference between the high-voltage module and the low-voltage module, so that vehicles using this electrical structure can operate well.

[0091] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0092] The battery cell 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.

[0093] Vehicles are a common means of transportation. Vehicles include body structures. As vehicles develop, body structures are also constantly being improved to adapt to new vehicle development trends and needs.

[0094] Vehicles typically consist of a body structure, powertrain structure, and interior components. To alleviate the problems of high assembly difficulty and low production efficiency, the body structure can be divided into the upper body and the chassis; the upper body and chassis can be manufactured separately and then assembled. The upper body mainly includes the A-pillar, B-pillar, C-pillar, front and rear bulkheads, and front and rear doors. The chassis mainly consists of the body floor and frame. The frame is the main supporting and load-bearing structure of the chassis. For ease of assembly, the frame usually includes three sections: the front compartment, the chemical compartment, and the rear compartment. Some frames also include a subframe to connect to the vehicle's suspension system; the subframe is usually connected to the front compartment.

[0095] Please refer to Figure 1 and Figure 2 Vehicle 100 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or extended-range electric vehicles, etc. Vehicle 100 includes a body structure 101, which includes a superstructure 120 and a chassis 110. The superstructure 120 is connected to the chassis 110 for easy assembly and improved assembly efficiency. Furthermore, the superstructure 120 and chassis 110 can be manufactured separately for easier processing and manufacturing, reducing the manufacturing difficulty of the body structure 101.

[0096] In some embodiments, the chassis 110 includes a frame 200 that supports the upper body 120.

[0097] In some embodiments, a battery device 300 is disposed inside the vehicle 100, and the battery device 300 may be located at the bottom, front, or rear of the vehicle 100. The battery device 300 can be used to power the vehicle 100; for example, the battery device 300 can serve as the operating power source for the vehicle 100. The vehicle 100 may also include an electrical structure 500 and a motor 400, the electrical structure 500 being used to control the battery device 300 to supply power to the motor 400, for example, to meet the power requirements of the vehicle 100 during starting, navigation, and driving.

[0098] In some embodiments, the battery device 300 can not only serve as the operating power source for the vehicle 100, but also as the driving power source for the vehicle 100, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 100.

[0099] Please see Figure 1 and Figure 2In some embodiments, the vehicle 100 and chassis 110 have multiple orientations, including: up, down, front, rear, left, and right, all of which are based on the orientation of the vehicle 100. That is, the direction from the front to the rear of the vehicle is the front-to-back direction, the direction from the roof to the bottom of the vehicle is the top-to-bottom direction, and the driver's seat and passenger seat are arranged in a left-right direction. For example, the front-to-back direction of the vehicle 100 is also called the length direction, which is the X direction; the left-to-right direction of the vehicle 100 is also called the width direction, which is the Y direction; and the height direction of the vehicle 100 is also called the vertical direction, which is the Z direction. Correspondingly, in the forward-backward direction (X) of vehicle 100, the forward direction refers to the direction vehicle 100 faces forward, i.e., forward is the F direction; the backward direction refers to the direction vehicle 100 faces backward, i.e., backward is the B direction. In the left-right direction (Y) of vehicle 100, the right direction refers to the direction vehicle 100 faces to the right, i.e., right is the R direction; the left direction refers to the direction vehicle 100 faces to the left, i.e., left is the L direction. In the height direction (Z) of vehicle 100, the upward direction refers to the direction vehicle 100 faces upward, i.e., upward is the U direction; the downward direction refers to the direction vehicle 100 faces downward, i.e., downward is the D direction. The up, down, forward, backward, left, and right positions of the frame 200 are consistent with the corresponding up, down, forward, backward, left, and right positions of vehicle 100. In addition, for the 200 frame, the longitudinal direction is along the front-to-back direction X, which allows for a certain error or small angular deviation, such as within 10 degrees; the lateral direction is along the left-to-right direction Y, which also allows for a certain error or small angular deviation, such as within 10 degrees.

[0102] As an example, a battery cell assembly can be a battery module, which consists of multiple battery cells 320 arranged and fixed together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells 320 together with cable ties.

[0103] In some embodiments, the battery device 300 may be a battery pack, which includes an energy chamber 310 and one or more individual battery cells housed in the energy chamber 310.

[0104] As an example, the battery cell assembly can be a battery module, which can be housed in the energy compartment 310 by fixing the battery module in the energy compartment 310.

[0105] As an example, the battery cell assembly can also be housed in the energy compartment 310 by directly fixing multiple battery cells 320 to the energy compartment 310.

[0106] In some embodiments, the energy compartment 310 may include a top cover 311, a frame 313, and a bottom plate 312. The top cover 311 and the bottom plate 312 are respectively connected to opposite sides of the frame 313, thereby forming a closed space inside the energy compartment 310 to accommodate the battery cells 320. The frame 313 refers to the partial structure forming the peripheral sidewall of the energy compartment 310, the top cover 311 refers to the plate-like structure forming the top of the energy compartment 310, and the bottom plate 312 refers to the plate-like structure forming the bottom of the energy compartment 310.

[0107] In some embodiments, the energy chamber 310 can be manufactured as a box structure to facilitate manufacturing and assembly.

[0108] In some embodiments, the energy compartment 310 may include a first housing and a second housing, which are fastened together to form a closed space inside the energy compartment 310 to house the battery cells 320. Here, "closed" refers to covering or shutting down, and can be either sealed or unsealed. The first housing may be the top cover or the bottom plate of the energy compartment 310.

The length direction of the energy compartment 310 is a first length direction X1, the width direction is a first width direction Y1, and the height direction is a first height direction Z1. Since the energy compartment 310 defines the shape of the battery device 300, the first length direction X1 is the length direction of the battery device 300, the first width direction Y1 is the width direction of the battery device 300, and the first height direction Z1 is the height direction of the battery device 300.

[0117] In some embodiments, when the chassis 110 includes a battery device 300 and an electrical structure 500, the electrical structure 500 is mounted on the battery device 300. This allows the electrical structure 500 to be supported by the battery device 300 and facilitates connection between the electrical structure 500 and the battery device 300, thereby controlling the power distribution and charging / discharging of the battery device 300. Furthermore, the battery device 300 is housed in the chassis 110 to provide power for its operation; mounting the electrical structure 500 on the battery device 300 allows for the inclusion of more individual battery cells 320 within the battery device 300, thereby increasing its energy density.

[0120] The rear seating area refers to the area on the battery device 300 corresponding to the rear seats.

[0121] By installing the electrical structure 500 in the rear seating area of ​​the battery unit 300, the chassis 110 can reduce the passenger space occupied in the vehicle 100 when in use, and to a certain extent, the electrical structure 500 can also support the rear seats.

[0122] In some embodiments, when the battery device 300 includes an energy chamber 310, the electrical structure 500 is mounted on the energy chamber 310, and the energy chamber 310 supports the electrical structure 500. This allows the electrical structure 500 to not occupy space within the energy chamber 310, enabling the energy chamber 310 to accommodate a larger number of battery cells 320, thereby increasing the capacity of the energy chamber 310. The electrical structure 500 can be a structure used to control the distribution of electrical energy and the charging and discharging of the battery device 300.

The height of the electrical structure 500 is less than or equal to the height of the rear seat height limiting plate 330. The rear seat height limiting plate 330 is a plate installed on the chassis at the location where the rear seats are installed. The function of this plate is to define the required height for the installation of the rear seats, while the height of other components must be lower than this plate to facilitate the installation of the rear seats. In addition, the rear seat height limiting plate 330 can also support the rear seats. Making the height of the electrical structure 500 less than or equal to the height of the rear seat height limiting plate 330 facilitates the installation of both the electrical structure 500 and the rear seats.

The low-voltage zone 540 refers to a portion of the containment space 510 that is separated from it. The isolation arrangement of high-voltage zone 530 and low-voltage zone 540 means that high-voltage zone 530 and low-voltage zone 540 are separated. For example, a partition can be installed in the receiving space 510 to separate high-voltage zone 530 and low-voltage zone 540; for example, a box or enclosure can be installed in the receiving space 510 to enclose high-voltage zone 530, thereby separating high-voltage zone 530 and low-voltage zone 540; for example, a box or enclosure can be installed in the receiving space 510 to enclose low-voltage zone 540, thereby separating high-voltage zone 530 and low-voltage zone 540; for example, multiple boxes or enclosures can be installed in the receiving space 510 to enclose high-voltage zone 530 and low-voltage zone 540 respectively, thereby separating high-voltage zone 530 and low-voltage zone 540.

[0131] As an example, the high-voltage module 522 includes a battery high-voltage module for controlling the charging and discharging of individual battery cells, and / or a vehicle high-voltage module for driving the vehicle 100.

[0132] A battery high-voltage module refers to the circuit structure in the battery device 300 used to control the charging and discharging of individual battery cells. For example, the battery high-voltage module performs voltage conversion and regulation, such as boosting the lower voltage output by the battery device 300 to a higher operating voltage to meet the needs of specific equipment or systems. As an example, in the vehicle 100, it converts the DC power from the battery device 300 into the high-voltage AC power required to drive the motor.

Furthermore, the vehicle's high-voltage module plays a role in system control and coordination, working closely with the vehicle's control system to achieve precise control of the high-voltage system. Based on factors such as the vehicle's driving status, driver commands, and battery status, it adjusts the high-voltage system's operating mode and parameters to ensure the safe and stable operation of the vehicle, coordinating the work of various high-voltage components, such as the drive motor, battery management unit, and charging system, to achieve integrated operation of the entire vehicle's high-voltage system. Finally, the vehicle's high-voltage module provides safety protection, incorporating multiple safety protection functions to prevent harm to the vehicle and occupants in case of high-voltage system malfunctions. These include overvoltage protection, overcurrent protection, short-circuit protection, and leakage protection. When an abnormality occurs in the high-voltage system, the module can promptly cut off the high-voltage power supply to ensure the safety of the vehicle and occupants. As an example, a vehicle's high-voltage module may include a DC-DC converter, a power distribution unit, etc.

[0135] As an example, the high-voltage module 522 may consist only of the battery high-voltage module, so the electrical structure 500 may be used only for the battery device 300. Of course, if the high-voltage module 522 consists only of the battery high-voltage module, the electrical structure 500 may also be applied to the chassis 110 of the vehicle 100.

[0136] As an example, high-voltage module 522 may consist of only the vehicle high-voltage module in order to control the vehicle 100 to operate well.

[0137] As an example, in the case where the high-voltage module 522 includes a battery high-voltage module and a vehicle high-voltage module, integrating the battery high-voltage module and the vehicle high-voltage module into the housing 51 can improve the integration level. The battery high-voltage module can also avoid occupying the internal space of the battery device 300, thereby reducing the volume of the battery device 300, increasing the energy density of the battery device 300, and reducing the thermal impact between the battery high-voltage module and the battery cells.

[0138] Low-voltage module 521 refers to at least a portion of the low-voltage circuit structure or electronic device in electrical structure 500 used to control signal transmission, low-voltage power distribution and use.

As an example, electronic control module 52 may also include a communication module for communication between the chassis 110 of vehicle 100 and external sources. As an example, electronic control module 52 may also include a module for communication between battery device 300 and external sources.

[0139] As an example, low-voltage module 521 includes a battery low-voltage module for monitoring and managing the charging and discharging of individual battery cells, and / or a vehicle low-voltage module for monitoring the operation of vehicle 100.

[0140] The battery low-voltage module refers to the circuit structure in the battery device 300 used to monitor and manage the charging and discharging of individual battery cells. The vehicle low-voltage module is the circuit structure in the vehicle 100 used to control the conversion and transmission of low-voltage electrical energy in order to monitor and manage the operation of the vehicle 100.

[0141] As an example, the low-voltage module 521 may consist only of the battery low-voltage module, so the electrical structure 500 may be used only for the battery device 300. Of course, if the low-voltage module 521 consists only of the battery low-voltage module, the electrical structure 500 may also be applied to the chassis 110 of the vehicle 100.

[0142] As an example, the low-voltage module 521 may consist of only the vehicle low-voltage module in order to monitor and manage the proper operation of the vehicle 100.

[0143] As an example, when the low-voltage module 521 includes a battery low-voltage module and a vehicle low-voltage module, integrating the battery low-voltage module and the vehicle low-voltage module into the housing 51 can improve the integration level. The battery low-voltage module can also avoid occupying the internal space of the battery device 300, thereby reducing the volume of the battery device 300 and increasing the energy density of the battery device 300.

[0144] The electronic control module 52 includes a high-voltage module 522 and a low-voltage module 521, which are integrated into the housing 51 to improve integration and reduce space occupation. When the electronic control module 52 is applied to the vehicle 100, it can reduce the space occupied in the vehicle 100.

[0145] The high-voltage module 522 is installed in the high-voltage area 530, that is, the high-voltage module 522 is placed in the high-voltage area 530 of the housing space 510.

[0146] The low-voltage module 521 is installed in the low-voltage area 540, that is, the low-voltage module 521 is placed in the low-voltage area 540 of the housing space 510.

[0147] Since the high-voltage zone 530 is isolated from the low-voltage zone 540, the high-voltage module 522 is placed in the high-voltage zone 530 of the housing space 510, and the low-voltage module 521 is placed in the low-voltage zone 540 of the housing space 510. Thus, the high-voltage module 522 and the low-voltage module 521 are also isolated, thereby reducing the electromagnetic interference between the high-voltage module 522 and the low-voltage module 521, so that the high-voltage module 522 and the low-voltage module 521 can operate well.

[0148] In the technical solution of this application embodiment, by separating a high-voltage area 530 and a low-voltage area 540 in the housing 51, the high-voltage module 522 of the electronic control module 52 is installed in the high-voltage area 530, and the low-voltage module 521 of the electronic control module 52 is installed in the low-voltage area 540. The high-voltage area 530 and the low-voltage area 540 are isolated, thereby isolating the high-voltage module 522 and the low-voltage module 521 to reduce electromagnetic interference between the high-voltage module 522 and the low-voltage module 521, so that the vehicle 100 using this electrical structure 500 can operate well.

[0166] A busbar is a flat, conductive structure made of conductive materials. Busbars can be made by braiding conductive wires or by using metals such as aluminum and copper. Due to their flat structure, a busbar with a given cross-sectional area will have a larger width, resulting in better heat dissipation and allowing it to withstand larger currents.

[0167] The first conductive busbar 551 refers to the conductive busbar installed at the bottom of the high-voltage box 53.

[0176] In some embodiments, if the thermally conductive layer 552 is made of an insulating material, the insulating layer 553 may not be provided.

[0177] In some embodiments, the bottom of the high-voltage box 53 may be provided with several protruding ribs 5321, which can not only increase the structural strength of the high-voltage box 53, but also play a certain role in heat dissipation. In addition, the provision of the protruding ribs 5321 can also separate the first conductive bus 551 from the high-voltage module 522 in the high-voltage box 53, increasing the distance between the first conductive bus 551 and the high-voltage module 522, thereby improving the safety of the circuit; in addition, the provision of the protruding ribs 5321 can also reduce the contact area between the high-voltage box 53 and the first conductive bus 551, thus reducing the impact of the heat from the first conductive bus 551 on the high-voltage module 522 inside the high-voltage box 53.

Furthermore, since the high-voltage module 522 often requires the use of conductive components capable of handling high currents for connection, the overall structural strength of the high-voltage module 522 is high after the electronic components are connected. Placing the main portion of the control harness 561 inside the high-voltage box 53 facilitates the connection of the control harness 561 to the high-voltage module 522, followed by the overall installation within the high-voltage box 53, and then the installation of the high-voltage box 53 within the housing 51, simplifying assembly. Additionally, this structure allows the high-voltage box 53 to cover a larger area of ​​the high-voltage module 522, better shielding the electromagnetic waves generated by the high-voltage module 522 and reducing the impact on the low-voltage module 521.

[0186] In some embodiments, a support structure may be provided on the high-voltage box 53, such as a buckle, hook or other structure, to connect the control harness 561 and fix and support the control harness 561.

[0187] In some embodiments, please refer to Figure 7 , Figure 13 and Figure 14 The control harness 561 is fixed to the harness bracket 562 by cable ties 563.

The first pre-charge relay 5704 is mainly used for pre-charging the high-voltage capacitors. Because the high-voltage module 522 of the electronic control module 52 contains many large-capacity capacitors, such as DC bus capacitors, if the high-voltage power supply is directly connected to these capacitors when the vehicle 100 starts, a large charging current will be generated because the voltage across the capacitors cannot change abruptly. This could damage components in the circuit or even cause a safety accident. The function of the pre-charge relay is to connect to the capacitors through a pre-charge resistor 5706 before officially connecting the high-voltage power supply, pre-charging the capacitors with a small current, gradually increasing the voltage across the capacitors to approach the power supply voltage. When the capacitor voltage reaches a certain value, the main relay 5703 is closed, directly connecting the high-voltage power supply to the circuit. At this time, because the capacitors have been pre-charged, the charging current is greatly reduced, thus protecting the circuit components.
