[0063] With the rapid development of new energy vehicles and the continuous increase in motor power and power density, the demands on the performance and heat dissipation of the supporting capacitors within the motor controller are also increasing. This leads to problems such as severe overheating and increased size of the integrated module, which not only hinders the improvement of the motor controller's power density but also poses risks to the reliability of the motor controller's high-voltage circuit. Traditional integrated modules can no longer meet the reliability requirements of capacitors in high-power, highly integrated motor controllers.

[0064] With the increasing demands for electromagnetic compatibility and reliability of motor controllers, their electromagnetic compatibility (EMC) performance and circuit protection functions are becoming more important. Currently, the integrated modules in motor controllers are all custom-developed and have limited functions. These integrated modules, along with filtering modules, circuit protection modules, and relays, are installed in other locations within the motor controller, resulting in wasted space, prolonged and deteriorated signal transmission loops, reduced performance of filtering modules, decreased response speed of circuit protection modules, and reduced reliability. Furthermore, these components are difficult to securely fix within the controller, increasing the risk of failure due to vibration.

[0065] Example 1:

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As described in Embodiment 1 of this application, an integrated module 100 is provided, including:

[0067] At least two types of secondary circuit devices, which are suitable for assisting the operation of primary circuit devices;

[0068] The housing 190 contains at least two types of secondary circuit devices.

[0069] By placing at least two secondary circuit devices in the same housing to form an integration of multiple secondary circuit devices, and integrating at least two secondary circuit devices in the controller into an integrated module, space is saved, the space utilization of the controller is improved, the signal transmission loop is simplified, and the reliability is improved.

[0070] Secondary circuit devices refer to devices belonging to the secondary circuit. The secondary circuit includes all low-voltage circuits such as measurement circuits, relay protection circuits, switch control and signal circuits, operating power supply circuits, and electrical interlocking circuits for circuit breakers and disconnectors. These secondary devices are interconnected to form electrical circuits for monitoring, controlling, regulating, and protecting primary equipment. Secondary equipment does not directly participate in power transmission; it is only low-voltage electrical equipment that monitors, controls, regulates, and protects primary equipment. It is indirectly connected to the main circuit through instrument transformers to ensure the safe and stable operation of the power system.

[0071] At least two secondary circuit devices are secondary circuit devices with different functions and roles, such as monitoring, control, regulation, and protection functions, and are placed in the same housing.

[0072] Furthermore, at least two secondary circuit devices include protection devices and / or control devices, wherein the protection devices are adapted to protect the circuit in which the integrated module 100 is located from damage by electrical signals, and the control devices are adapted to regulate the electrical signals.

[0073] Protective devices are electronic components used to protect electronic circuits, equipment, or systems from damage caused by abnormal conditions such as electrical overload, short circuit, overvoltage, overcurrent, and electrostatic discharge. Common protective devices include resistors, capacitors, fuses, discharge tubes, and electrostatic discharge protectors. Protective devices can be classified according to their working principle and materials. Based on working principle, they can be divided into current limiters, voltage regulators, ESD protectors, and overcurrent fuses. Based on materials, they can be divided into carbon film resistors, metal film resistors, fuses, gas discharge tubes, and silicon diodes. Protective devices have functions such as short-circuit protection, overvoltage protection, overcurrent protection, electrostatic discharge protection, and overload protection. The integrated module 100 can have at least two secondary circuit devices with different functions from the above-mentioned protective devices, thereby achieving the integration of multiple protective devices.

[0074] Controllers are key components in a circuit used to regulate, control, and optimize circuit performance. They can adjust circuit parameters as needed to ensure stable and efficient operation under various working conditions. Common controllers in practical circuits include switches, relays, sensors, and capacitors. Controllers have regulating, controlling, and optimizing functions. The at least two secondary circuit devices in the integrated module 100 can be at least two controllers with different functions, thereby achieving the integration of multiple controllers.

[0075] The at least two secondary circuit devices in the integrated module 100 can also be at least two control devices with different functions among the aforementioned protection devices and control devices, thereby realizing the integration of multiple control devices. For example, integrating a device with overvoltage protection function and a device with control function.

[0076] Furthermore, the control device includes a capacitor core 120 and / or a switching assembly, wherein the capacitor core 120 is adapted to stabilize the electrical signal and the switching assembly is adapted to control the on / off state of the electrical signal.

[0077] The function of the capacitor core 120 is to store charge and electrical energy, regulate the transmission path of electrical signals, and stabilize circuit performance.

[0078] When the control device includes a capacitor core 120 or a switching assembly, the integrated module 100 also includes at least one protection device. When the control device includes both a capacitor core 120 and a switching assembly, the integrated module 100 may or may not include a protection device, or it may include at least one protection device.

[0079] Furthermore, the input terminal of the capacitor core 120 is adapted to be connected to the power supply module 220, and the output terminal of the capacitor core 120 is adapted to be connected to the primary circuit device, so as to realize the connection between the power supply module 220 and the primary circuit device. The capacitor core 120 adjusts the electrical signal between the power supply module 220 and the primary circuit device to ensure the stability of the electrical signal and circuit performance.

[0080] Furthermore, such as Figure 4 , Figure 7 , Figure 8 As shown, there are multiple capacitor cores 120, and the multiple capacitor cores 120 are connected together.

[0081] The filter module 110 is connected to at least one capacitor core 120. The integrated module integrates the filtering function of the filter module 110. The current enters at least one capacitor core 120 through the filter component 110, eliminating noise in the input signal of the integrated module 100, achieving efficient noise suppression and interference filtering, improving space utilization, shortening the signal transmission loop, and improving the performance of the filter module 110.

[0082] Furthermore, the switching assembly includes a first switch 150 disposed between at least two capacitor cores 120.

[0083] The integrated module 100 integrates a first switch 150 to realize the on / off control function between multiple capacitor cores 120. The first switch 150 is set between the negative terminals of the multiple capacitor cores 120 to control the on / off of the multiple capacitor cores 120 negative terminals; the first switch 150 is set between the positive terminals of the multiple capacitor cores 120 to control the on / off of the multiple capacitor cores 120 positive terminals; the first switch 150 is set between the positive and negative terminals of the multiple capacitor cores 120 to control the on / off of the multiple capacitor cores 120 positive terminals and the on / off of the multiple capacitor cores 120 negative terminals.

[0084] The specific structure of the first switch 150 is not limited; it can be a single-pole switch, double-pole switch, three-pole switch, four-pole switch, etc., selected according to different requirements. For example, when the first switch 150 is set between the positive and negative terminals of the two capacitor cores 120, it can be selected as follows: Figure 4 The two single-pole switches shown control the on / off state between the positive terminals of the two capacitor cores 120, respectively. Alternatively, a double-pole switch can be selected to control the on / off state between the positive terminals of the two capacitor cores 120, either individually or simultaneously.

[0085] The first switch 150 is usually a relay. Commonly used relays include electromagnetic relays, solid-state relays, thermal relays, reed relays, time relays, polarized relays, high-frequency relays, optical relays, acoustic relays, Hall effect relays, etc.; or voltage relays, current relays, temperature relays, etc.

[0086] The first switch 150 is disposed among multiple capacitor cores 120 to reduce the connection lines between the first switch 150 and the capacitor cores 120 and simplify the structure.

[0087] like Figure 6 As shown, when the first switch 150 consists of two switches, it includes a first positive switch 151 and a first negative switch 152. The first positive switch 151 connects to the positive terminals of the two capacitor cores 120, and the first negative switch 152 connects to the negative terminals of the two capacitor cores 120. Along the X direction, the first positive switch 151 and the first negative switch 152 are positioned between the two capacitor cores 120; along the Y direction, the first positive switch 151 and the first negative switch 152 are sequentially arranged, with the Y direction intersecting the X direction. The first positive switch 151 and / or the first negative switch 152 are electrically connected to the busbar copper busbar by bolts and fixed inside the housing with potting compound.

[0088] Two first positive switches 151 may be included, each used to control the connection or disconnection between the positive terminals of the two capacitor cores 120, or to control the connection or disconnection between the positive terminal of the first module output terminal 174 and the positive terminal of any capacitor core 120. Two first negative switches 152 may be included, each used to control the connection or disconnection between the negative terminals of the two capacitor cores 120, or to control the connection or disconnection between the negative terminal of the first module output terminal 174 and the negative terminal of any capacitor core 120. Along the Z-direction, the two first positive switches 151 are sequentially arranged, and / or the two first negative switches 152 are sequentially arranged, with the Z-direction, Y-direction, and X-direction intersecting.

[0089] The first switch 150 is used to receive signals from the control system to control the on / off state of the first module output terminal 174 of the integrated module 100.

[0090] Furthermore, the switching assembly includes a second switch 160, one end of which is connected to the input terminal of the capacitor core 120, and the other end of which is adapted to be connected to the power supply module 220.

[0091] The second switch 160 is used to receive signals from the control system and control the connection between the external connection terminal 172 and the energy storage connection terminal 171, thereby realizing the connection control between the motor, the energy storage unit and the capacitor core 120.

[0092] The integrated module 100 integrates the fuse component 130, the first switch 150, and the second switch 160, enabling intelligent protection and high-speed response for the integrated module 100.

[0093] Furthermore, when the controller includes a capacitor core 120 and a switching assembly, the capacitor core 120 is connected to the switching assembly, which saves space, improves the space utilization of the controller, simplifies the signal transmission loop, and improves reliability.

[0094] Furthermore, it includes a control signal input terminal, which is connected to the capacitor core 120 and / or the switching assembly. When the control signal input terminal is connected to both the capacitor core 120 and the switching assembly, the number of control signal terminals can be reduced, the number of connecting components between the control signal input terminal and the capacitor core 120 and the switching assembly can be reduced, and costs are lowered.

[0095] Furthermore, the protection device includes a filter component 110 and / or a fuse component 130, wherein the filter component 110 is used to eliminate noise in the input electrical signal and the fuse component 130 is used to provide overload protection.

[0096] Insurance component 130 can be active insurance, passive insurance, or a combination of active and passive insurance.

[0097] The integrated module 100 integrates a fuse component 130, which provides protection for the integrated module 100, especially when the integrated module 100 is used in high-voltage scenarios. The two ends of the fuse component 130 are connected to the filter component 110 and the capacitor core 120, respectively, and the fuse component 130 is used to provide overload protection.

[0098] Fuse assembly 130 is a protective device installed in a busbar circuit; specifically, fuse assembly 130 is installed at least on the positive terminal. For example... Figure 2 , Figure 6 As shown, the fuse component 130 is positioned between the positive terminal of the filter component 110 and the positive terminal of the capacitor core 120, while the negative terminal of the filter component 110 is directly connected to the negative terminal of the capacitor core 120. When the fuse component 130 detects that the current at the positive terminal of the bus exceeds a preset current value, it sends a signal to the control system (e.g., a motor control unit, or MCU). The control system then controls the on / off state of the first switch 150 and / or the second switch 160 within the integrated module 100, thereby controlling the current flow and preventing damage to the integrated module 100 and the controller 200 caused by bus abnormalities. This improves product safety and reduces maintenance costs.

[0099] The current signal passes through the filter component 110 and enters the positive terminal of the bus in the integrated module 100. After being further connected to the fuse component 130, it is then connected to the positive terminal of the first capacitor component 121, and then passes through the first positive switch 151 to connect to the positive terminal of the second capacitor component 122. At the same time, the current signal can be directly connected to the negative terminal of the first capacitor component 121.

[0100] Connecting the filter module 110 to the capacitor core 120 integrates the filtering function of the filter module 110 while ensuring the basic functions of the integrated module 100. Current flows through the filter module 110 into the capacitor core 120, eliminating noise in the input signal of the integrated module 100, achieving efficient noise suppression and interference filtering, improving space utilization, shortening the signal transmission loop, and enhancing the performance of the filter module 110. The integrated module 100 integrates electrical isolation by setting the filter module 110, isolating high-voltage and low-voltage circuits, protecting components and personal safety, and effectively reducing the transmission of noise and interference between control signals and load circuits.

[0101] The filter module 110 isolates electromagnetic interference from the integrated module 100. The connection method between the filter module 110 and the capacitor core 120 is not specifically limited. For example, the filter module 110 can be electrically connected to the integrated module 100 by welding or connecting bolts.

[0102] The connection method between the filter module 110 and the housing 190 is not specifically limited. For example, the filter module 110 can be fixedly connected to the housing 190 by potting glue and bolts, which can achieve better filtering performance while saving the cost of producing the filter module 110 housing separately.

[0103] The specific implementation of the filter module 110 is not limited. For example, filtering can be implemented in the form of magnetic rings. For instance, the filter module 110 is an electronic component combination module that achieves filtering through two magnetic rings.

[0104] Furthermore, the input terminal of the filter component 110 is adapted to be connected to the power supply module 220, and the output terminal of the filter component 110 is connected to the input terminal of the capacitor core 120, so as to realize the connection between the filter component 110 and the capacitor core 120 in the integrated module 100.

[0105] Furthermore, the input terminal of the fuse component 130 is adapted to be connected to the power supply module 220, and the output terminal of the fuse component 130 is connected to the input terminal of the capacitor core 120, so as to realize the connection between the filter component 110 in the fuse component 130 and the capacitor core 120. At this time, there is no need to set the filter component 110 between the power supply module 220 and the fuse component 130. For example, the power supply module 220 can be a charging unit 222.

[0106] Furthermore, the input terminal of the fuse component 130 is connected to the output terminal of the filter component 110 to realize the connection between the filter component 110 and the capacitor core 120 in the fuse component 130. For example, the power supply module 220 can be an energy storage unit 221.

[0107] Furthermore, it includes a shield 191, which is disposed between the filter assembly 110 and the capacitor core 120.

[0108] By using the housing 190 of the integrated module 100 as a shielding barrier, and integrating the filter component 110, the integrated module 100 can achieve the filtering function. The shielding component 191 is integrated into the housing 190, which simplifies the structure, reduces costs, and achieves product lightweighting while ensuring shielding.

[0109] Furthermore, the housing 190 and the shielding component 191 are integrally connected.

[0110] The shielding component 191 is disposed on the portion of the housing 190 between the filter assembly 110 and the integrated module 100. The portion of the housing 190 not between the filter assembly 110 and the integrated module 100 is made of a non-shielding material, further reducing product costs. Furthermore, the lightweight nature of the non-shielding material further achieves weight reduction.

[0111] Furthermore, at least two secondary circuit devices are welded together via connecting assembly 140.

[0112] The connection component 140 is used to establish a connection between at least the first switch 150 and at least two capacitor cores 120, so as to realize the electrical connection between the first switch 150 and at least two capacitor cores 120, and enable the first switch 150 to control the on / off state between at least two capacitor cores 120.

[0113] like Figure 7 , Figure 8 As shown, the connection assembly 140 includes a first connector 141 and a third connector 143, and the connection assembly 140 includes a plurality of connection points 180 for connecting the first switch 150 and at least two capacitor cores 120.

[0114] The third connector 143 connects the first switch 150 and the positive terminals of at least two capacitor cores 120. The third connector 143 includes: a first switch connection point 185, a third switch connection point 187, a fifth switch connection point 189, a filter positive terminal connection point 181, and a fuse positive terminal connection point 183. Specifically, the first switch connection point 185 is connected to the positive terminal of the first positive switch 151, the third switch connection point 187 is connected to the positive terminal of the first negative switch 152, and the fifth switch connection point 189 is connected to the positive terminal of the second switch 160. The filter positive terminal connection point 181 is connected to the positive terminal of the filter assembly 110, and the fuse positive terminal connection point 183 is connected to the positive terminal of the fuse assembly 130.

[0115] The first connector 141 connects the first switch 150 and the negative terminals of at least two capacitor cores 120. The first connector 141 includes: a second switch connection point 186, a fourth switch connection point 188, a sixth switch connection point 193, a filter negative terminal connection point 182, and a fuse negative terminal connection point 184. Specifically, the second switch connection point 186 is connected to the negative terminal of the first positive switch 151, the fourth switch connection point 188 is connected to the negative terminal of the first negative switch 152, and the sixth switch connection point 193 is connected to the negative terminal of the second switch 160. The filter negative terminal connection point 182 is connected to the negative terminal of the filter assembly 110, and the fuse negative terminal connection point 184 is connected to the negative terminal of the fuse assembly 130.

[0116] Furthermore, at least two secondary circuit devices are installed into the housing 190 using an integral potting method, thereby achieving a fixed connection between the at least two secondary circuit devices and the housing 190.

[0117] Furthermore, when the control device includes a capacitor core 120, it also includes a heat sink 192 for dissipating heat from the capacitor core 120. The heat sink 192 typically employs one or more existing heat dissipation methods such as radiation, conduction, convection, and evaporation.

[0118] Furthermore, the first side of the heat dissipation part 192 contacts the capacitor core 120 to dissipate heat from the capacitor core 120.

[0119] The housing 190 of the integrated module 100 is connected to the capacitor core 120. The heat dissipation part 192 dissipates heat from the capacitor core 120, thereby improving the heat dissipation efficiency.

[0120] The heat dissipation method of the heat sink 192 is not specifically limited; it can be air cooling, water cooling, or liquid cooling. For example, when the heat sink 192 is configured as a water cooling channel, the heat sink 192 improves the heat dissipation efficiency of the capacitor core 120 and has good water cooling efficiency.

[0121] Furthermore, the heat dissipation unit 192 is disposed on the housing 190, realizing the integration of the heat dissipation unit 192 and the housing 190, saving space and reducing costs. Figure 11 As shown, the heat dissipation part 192 is disposed on one side of the housing 190 along the Z direction. The heat dissipation part 192 is liquid-cooled. At this time, the housing 190 is provided with a liquid inlet and a liquid outlet (not shown in the figure) to realize the circulation of high-temperature liquid inside the heat dissipation part 192 and low-temperature liquid outside.

[0122] Furthermore, it also includes a module input terminal 170, which is used to input electrical signals.

[0123] The integrated module 100 enters through the module input terminal 170, passes through the filter component 110 to complete filtering, and isolates electromagnetic interference inside and outside the integrated module 100.

[0124] Furthermore, such as Figure 5 , Figure 6 As shown, the module input terminal 170 includes an energy storage connection terminal 171, which is connected to the input terminal of the filter component 110 and is used to connect to the energy storage unit.

[0125] The signal is connected to the energy storage unit through the energy storage connection terminal 171 and filtered through the 3-filter module to achieve electromagnetic isolation between the inside and outside of the integrated module 100.

[0126] An energy storage unit is a device that stores energy through a medium or equipment and releases it when needed. According to the energy storage method, physical energy storage mainly includes pumped hydro storage, compressed air storage, and flywheel energy storage; chemical energy storage mainly includes lead-acid batteries, lithium-ion batteries, sodium-sulfur batteries, and flow batteries; and electromagnetic energy storage mainly includes supercapacitor energy storage and superconducting energy storage.

[0127] Furthermore, the module input terminal 170 includes an external connection terminal 172, which is connected to the input terminal of the capacitor core 120 and is used to connect to an external current input terminal.

[0128] The external connection terminal 172 includes an external negative terminal 1721, an external positive terminal 1722, and an external N-terminal 1723. The external negative terminal 1721 is a connection point of the first connector 141, used to output voltage to the integrated module 100; the external positive terminal 1722 is a connection point of the third connector 143, used to input voltage to the integrated module 100; and the external N-terminal 1723 is used for grounding. The positions of the external negative terminal 1721, external positive terminal 1722, and external N-terminal 1723 are not specifically limited and can be as follows: Figure 8 As shown, they are set sequentially along the X direction.

[0129] The current signal can also be connected to the external connection terminal 172 through one end of the second switch 160, and the other end of the second switch 160 can be connected to the fuse component 130. The specific arrangement is not limited to any particular method and can be as follows: Figure 6 As shown, along the Y direction, the second switch 160 and the fuse assembly 130 are arranged sequentially, and along the X direction, both the second switch 160 and the fuse assembly 130 are arranged next to the filter assembly 110. In this way, the second switch 160, the fuse assembly 130 and the filter assembly 110 can be arranged compactly, with high space utilization, effectively reducing the size of the integrated module 100.

[0130] The installation and fixing methods of the second switch 160, fuse assembly 130, and filter assembly 110 are not particularly limited. The second switch 160, fuse assembly 130, and filter assembly 110 can be electrically connected to the bus copper busbar with bolts and fixed inside the housing with glue.

[0131] Furthermore, it also includes a module output terminal 173, which is connected to the output terminal of the capacitor core 120 and is used to output signals.

[0132] The module output terminal 173 includes a first module output terminal 174 and a second module output terminal 175. The first module output terminal 174 is connected to one end of the fourth connector 144, and the other end of the fourth connector 144 is connected to the first capacitor assembly 121. The second module output terminal 175 is connected to the fifth connector 145, and the other end of the fifth connector 145 is connected to the second capacitor assembly 122.

[0133] Example 2:

[0134] like Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 As shown, Embodiment 2 of this application provides a controller 200, which includes the aforementioned integrated module 100.

[0135] The integrated module 100, filter module 110, fuse assembly 130, and switching assembly (including first switch 150 and second switch 160) are integrated in the controller 200, saving space, improving the reliability of the controller, enhancing the positioning of components such as capacitor core 120, filter module 110, fuse assembly 130, and switching assembly, greatly reducing the risk of failure caused by vibration, and improving the electromagnetic compatibility of the controller 200. The small size of the integrated module 100 is beneficial for increasing the power density of the controller 200 and improving the reliability of the high-voltage circuit of the controller 200.

[0136] The controller 200 integrates a fuse component 130, a first switch 150, and a second switch 160, enabling intelligent protection and high-speed response when the controller 200 is applied to a high-voltage DC side circuit.

[0137] The function of capacitor core 120 in the controller is as follows: inductance between multiple primary circuit devices, weakening the peak voltage of the bus, smoothing the bus voltage; absorbing high pulse current at the bus terminal; reducing the influence of overcharging and transient voltage at the bus terminal.

[0138] Furthermore, it also includes a motor control component 240, the input of which is connected to the output of the integrated module 100.

[0139] The motor control component 240 is a device for controlling the energy transfer between the power source and the drive motor, and includes at least a control signal interface circuit, a drive motor control circuit, and a drive circuit. The motor control component 240 can be a power semiconductor device, such as an insulated-gate bipolar transistor (IGBT), to realize energy conversion and transfer, or to realize the mutual conversion between DC and AC.

[0140] The motor control component 240 is connected to the capacitor core 120. Specifically, the motor control component 240 is connected to the module output terminal 173 (the fourth connector 144 and / or the fifth connector 145), realizing the electrical integration of the motor control component 240 and the integrated module 100.

[0141] The motor control component 240 is attached to the housing 190 of the integrated module 100, realizing the structural integration of the motor controller, simplifying the overall wiring of the system, and reducing the design, processing, and assembly of the housing, thereby reducing production costs and production time.

[0142] Furthermore, the integrated module 100 includes a heat dissipation unit 192, and the motor control component 240 exchanges heat with the heat dissipation unit 192 to achieve heat dissipation of the motor control component 240.

[0143] The housing 190 of the integrated module 100 is connected to the motor control component 240 and shares a heat dissipation part 192 with the motor control component 240. Through the heat dissipation part 192, heat dissipation of the capacitor core 120 and / or the motor control component 240 is achieved, thereby improving heat dissipation efficiency.

[0144] The heat dissipation method of the heat sink 192 is not specifically limited; it can be air cooling, water cooling, or liquid cooling. For example, when the heat sink 192 is configured as a water cooling channel, the heat sink 192 improves the heat dissipation efficiency of the motor control component 240 and has good water cooling efficiency.

[0145] Furthermore, the second side of the heat sink 192 is in contact with the motor control assembly 240, and the second side of the heat sink 192 and the first side of the heat sink 192 are located on different sides of the heat sink 192.

[0146] A heat sink 192 is disposed on the housing 190, a capacitor core 120 is disposed inside the housing 190, and a motor control assembly 240 is disposed outside the housing 190, corresponding to the heat sink 192. Figure 11As shown, the heat dissipation part 192 is disposed on the top of the housing 190, the capacitor core 120 is disposed inside the housing 190, and the motor control component 240 is disposed on the outside of the top of the housing 190 corresponding to the heat dissipation part 192. This allows the integrated module 100 to integrate more functions, reduce costs, and ensure the heat dissipation efficiency of the capacitor core 120 and the motor control component 240.

[0147] Furthermore, there are multiple motor control components 240, and the input terminal of at least one motor control component 240 is connected to the output terminal of at least one capacitor core 120.

[0148] Specifically, when there are two motor control components 240, each motor control component 240 includes a second motor control component 242 and a first motor control component 241. The second motor control component 242 and the first motor control component 241 are respectively connected to the output terminal 174 of the first module and the output terminal 175 of the second module.

[0149] The DC circuit of the second motor control component 242, after passing through the second capacitor component 122, is connected to the first motor control component 241 through the first module output terminal 174. The DC circuit of the second motor control component 242, after passing through the first capacitor component 121, is connected to the second motor control component 242 through the second module output terminal 175.

[0150] The arrangement of the first motor control component 241 and the second motor control component 242 is not specifically limited. For example, the first motor control component 241 and the second motor control component 242 may be arranged side by side in the X direction and positioned on one side of the integrated module 100 in the Z direction. The first motor control component 241 and / or the second motor control component 242 are electrically connected to the module output terminal 173 by welding and fixed to the housing 190 by bolts.

[0151] Furthermore, it also includes a motor 210, which is connected to a motor control assembly 240.

[0152] Controller 200 is a motor controller. One motor control component 240 typically controls one motor 210. The controller can be a single-motor controller or a multi-motor controller. Figure 11 The dual-motor controller shown integrates dual inverter functionality. In the dual-motor controller, the two motors 210 are respectively connected to the second motor control component 242 and the first motor control component 241, realizing multiple driving modes such as hybrid and pure electric, thus enriching the controller's functions.

[0153] Furthermore, it also includes a power supply module 220, which is connected to the integrated module 100.

[0154] The power supply module 220 includes an energy storage unit 221 and / or a charging unit 222. The energy storage unit 221 is more portable and flexible in use compared to the charging unit 222. The charging unit 222 can also provide energy; it can be a single charging method or multiple charging methods, such as DC or AC. Either the energy storage unit 221 or the charging unit 222 can be used as the power supply module 220. Generally, the energy storage unit 221 faces the risk of running out of energy, and is therefore supplemented by the charging unit 222.

[0155] When the power supply module 220 has both energy storage and charging functions, the power supply module 220 is a single entity. The power supply module 220 is connected to the integrated module 100, thereby providing energy input or signal input to the integrated module 100.

[0156] Example 3:

[0157] like Figure 15 As shown, a vehicle 300 includes the integrated module 100 or the controller 200.

[0158] By integrating the capacitor core 120, fuse assembly 130, and switch assembly into the integrated module 100, the number of independent components distributed in the controller 200 is reduced, the spatial layout is optimized, the space utilization of the vehicle 300 is improved, and material costs are reduced. The switch assembly and fuse assembly 130 do not require separate housing design, saving metal material costs. The design, processing, and assembly of the housing are reduced, thus lowering production costs and production time.
