[0017] Please also read Figure 1 , Figure 2 and Figure 3 The present application provides a vehicle-mounted integrated power controller 100, including a housing 10 and a circuit board 20. The housing 10 is provided with a housing cavity 11, and the circuit board 20 is arranged in the housing cavity 11. The housing 10 serves as the outer shell of the entire controller, providing physical support and protection to prevent the internal components from being affected by the external environment. A special housing cavity 11 is provided in the housing 10 for installing the circuit board 20 and other key components, so as to maximize the use of the internal space of the housing 10.

[0018] Among them, the circuit board 20 integrates a microprocessor chip (MCU, Microcontroller Unit) 21, an on-board charger (OBC, On-Board Charger) 22, a voltage converter (DC-DC, Direct Current to Direct Current Converter) 23, an on-board heater control chip (PTC, Positive Temperature Coefficient) 24 and an on-board compressor control chip (CCM, Compressor Control Module) 25. The microprocessor chip 21 is connected to the on-board charger 22, the voltage converter 23, the on-board heater control chip 24 and the on-board compressor control chip 25 respectively. The on-board charger 22 is configured to convert alternating current into direct current, the voltage converter 23 is configured to perform voltage conversion, the on-board heater control chip 24 is configured to control the on-board heater, and the on-board compressor control chip 25 is configured to control the on-board compressor.

[0019] Specifically, the microprocessor chip 21 acts as a central controller, responsible for coordinating and managing the operations of all other modules to ensure efficient and stable operation of the entire control system. Among them, by building algorithms and sensor feedback into the vehicle-mounted integrated power controller 100, the microprocessor chip 21 can monitor the status of each subsystem in real time and make corresponding adjustments to optimize the performance and energy efficiency of the entire vehicle-mounted integrated power controller 100. At the same time, by centrally controlling multiple functional modules through a microprocessor chip 21, the number of processors required can be reduced, thereby reducing hardware costs.

[0020] The on-board charger 22 is generally used to convert AC power into DC power to charge the battery of the vehicle 200. The on-board charger 22 is integrated on the circuit board 20 to simplify the structure of the charging system, thereby improving the conversion efficiency. The on-board charger 22 can usually support multiple charging modes (such as fast charging and slow charging), and can automatically adjust the charging parameters according to the battery status to extend the battery life.

[0021] The voltage converter 23 is used to perform necessary voltage conversion tasks to ensure that different on-board electrical appliances obtain appropriate power supply voltages.

[0022] The vehicle heater control chip 24 is used to control the vehicle heater in the vehicle 200, and can also preheat the battery in a cold environment, thereby ensuring the normal operation of the integrated power supply.

[0023] The vehicle compressor control chip 25 is used to control the vehicle compressor in the vehicle 200, that is, it is responsible for the compressor operation of the air-conditioning system, achieving energy saving and cooling / heating effects, thereby adapting to environmental changes, maintaining a constant temperature in the vehicle, and improving the driving experience.

[0024] In actual operation, the microprocessor chip 21, as a central controller, can flexibly adjust the working status of each module according to the actual needs of the vehicle 200, such as automatically adjusting the power of the vehicle heater according to the temperature, or optimizing the charging strategy according to the driving conditions. The microprocessor chip 21 can monitor and accurately adjust the power output of each subsystem in real time to achieve more efficient energy utilization. At the same time, since all control logics are executed on the same circuit board 20, the information transmission speed is faster, which improves the dynamic response capability of the system, especially when the load changes frequently.

[0025] In the above-mentioned vehicle-mounted integrated power supply controller 100, multiple functional modules are integrated on a circuit board 20, which can improve the output efficiency of the integrated power supply. At the same time, multiple functional modules are placed in the accommodating cavity 11 of the shell 10, so as to rationally utilize the space in the vehicle-mounted integrated power supply controller 100, reduce the preparation cost, and simplify the installation and maintenance process of the entire vehicle-mounted integrated power supply controller 100.

[0026] In one embodiment, the circuit board 20 integrates all key control and drive circuits, including four modules: a vehicle charger 22, a voltage converter 23, a vehicle heater control chip 24, and a vehicle compressor control chip 25. The above modules share an integrated chip to achieve universal control circuits, reduce the number of processors required, and thus reduce hardware costs. At the same time, the above modules also coordinate the operation of each module through a microcontroller chip to ensure the efficient operation of the entire system and dynamically adjust the working status of each module according to real-time needs.

[0027] Please also read Figure 1 and Figure 3 In one embodiment, the housing 10 includes a main body 12 and an upper cover 13. The main body 12 is hollow inside, and the main body 12 and the upper cover 13 form a receiving chamber 11. The main body 12 includes a bottom plate 121 and a first side plate 122, a second side plate 123, a third side plate 124 and a fourth side plate 125 arranged around the bottom plate 121. The bottom plate 121 and the upper cover 13 are arranged relative to each other along a first direction Z, the first side plate 122 and the third side plate 124 are arranged relative to each other along a second direction X, and the second side plate 123 and the fourth side plate 125 are arranged relative to each other along a third direction Y, wherein the first direction Z, the second direction X and the third direction Y are perpendicular to each other. Through the above arrangement, the first side plate 122, the second side plate 123, the third side plate 124 and the fourth side plate 125 are arranged around the bottom plate 121, and cooperate with the upper cover 13 to form a closed cubic or rectangular frame, thereby forming a receiving chamber 11 for accommodating the circuit board 20 and other key components.

[0028] In one embodiment, the bottom plate 121 , the first side plate 122 , the second side plate 123 , the third side plate 124 and the fourth side plate 125 are an integrally formed structure, and the integrally formed main body 12 structure can improve the structural strength of the shell 10 .

[0029] Please also read Figure 2 , Figure 3 and Figure 4 In one embodiment, the first side panel 122 is provided with a vehicle heater interface 1221 and a vehicle compressor interface 1222. The input end of the vehicle heater interface 1221 is connected to the vehicle heater control chip 24, and the output end of the vehicle heater interface 1221 is used to connect to the vehicle compressor. The vehicle compressor interface 1222 is spaced apart from the vehicle heater interface 1221, the input end of the vehicle compressor interface 1222 is connected to the vehicle compressor control chip 25, and the output end of the vehicle compressor interface 1222 is used to connect to the vehicle compressor.

[0030] Specifically, the vehicle heater interface 1221 receives control signals and power supply from the microprocessor chip 21. At the same time, the vehicle heater interface 1221 can be connected to the vehicle heater for transmitting control signals and power to achieve the heating function. The vehicle compressor interface 1222 is connected to the vehicle compressor control chip 25 to receive control instructions and power supply from the microprocessor chip 21. At the same time, the vehicle compressor interface 1222 is connected to the vehicle compressor for transmitting control signals and power to drive the compressor to work.

[0031] Through the centralized management of the microprocessor chip 21, the vehicle heater control chip 24 and the vehicle compressor control chip 25 can flexibly adjust their respective working states according to the actual needs of the vehicle 200, such as automatically adjusting the heater power according to the temperature, or optimizing the compressor operation according to the driving conditions. The interfaces can directly exchange data through the internal bus, enhancing the overall coordination and intelligence level of the entire vehicle integrated power controller 100, thereby ensuring optimal performance and energy efficiency.

[0032] Please continue reading Figure 2 , Figure 3 and Figure 4 In one embodiment, the third side panel 124 is provided with a signal interface 1241, the input end of the signal interface 1241 is connected to the vehicle controller (not shown), and the output end of the signal interface 1241 is connected to the vehicle charger 22, the voltage converter 23, the vehicle heater control chip 24 and the vehicle compressor control chip 25.

[0033] Specifically, the signal interface 1241 can receive control instructions and status information from the vehicle control unit (VCU), such as charging requirements, heating requests, compressor operation, etc. Through continuous data exchange, the microprocessor chip 21 in the vehicle integrated power controller 100 can monitor the status of the vehicle in real time and adjust the operation of each subsystem as needed.

[0034] When the signal interface 1241 is connected to the vehicle charger 22, it can transmit control signals and feedback information to manage the operation of the vehicle charger 22, including charging mode selection, current regulation, etc. When the signal interface 1241 is connected to the voltage converter 23, it can be used to adjust the output voltage of the voltage converter 23 to ensure that different loads obtain appropriate power supply voltages. When the signal interface 1241 is connected to the vehicle heater control chip 24, it can send control instructions to manage the working status of the vehicle heater, such as starting / stopping heating, adjusting power, etc. When the signal interface 1241 is connected to the vehicle compressor control chip 25, it can transmit control signals to adjust the compressor operation of the air-conditioning system, such as starting and stopping, speed adjustment, etc.

[0035] Through the above settings, all key modules communicate with the vehicle controller through a unified signal interface 1241, reducing other redundant lines, thereby improving communication efficiency. At the same time, all key modules on the circuit board 20 support high-speed data transmission, ensuring that the microprocessor chip 21 can obtain and process various status information in a timely manner, so as to make the best decision.

[0036] Please continue reading Figure 2 , Figure 3 and Figure 4 In one embodiment, the third side panel 124 is further provided with a slow charging interface 1242, the input end of the slow charging interface 1242 is used to input AC power, and the output end of the slow charging interface 1242 is used to connect to the on-board charger 22, so that the on-board charger 22 converts the AC power into DC power. Through the above configuration, the slow charging interface 1242 is connected to the on-board charger 22, and the on-board charger 22 is used to convert the AC power input from the slow charging interface 1242, such as the power grid, into DC power, and provide the DC power to other electrical equipment, that is, high-voltage component power distribution, and charging of high-voltage power batteries.

[0037] When the on-board charger 22 converts AC power into DC power, the output voltage and current can be adjusted according to the requirements of the battery management system (BMS). During the entire charging process, the microprocessor chip 21 continuously monitors the charging status, including parameters such as temperature, voltage, and current, and dynamically adjusts the charging strategy according to the actual situation, thereby ensuring a safe and efficient charging process.

[0038] Please continue reading Figure 2 , Figure 3 and Figure 4 In one embodiment, the third side panel 124 is also provided with a low voltage direct current (LVDC) interface. The input end of the low voltage direct current interface 1243 is connected to the voltage converter 23. The voltage converter 23 is used to convert high voltage direct current into direct current used by low voltage electrical equipment, for example, into 12V direct current to power the vehicle battery.

[0039] Please continue reading Figure 2 , Figure 3 and Figure 4 In one embodiment, the third side panel 124 is also provided with a DC high voltage interface 1244, the input end of which is connected to the vehicle charger 22, and is mainly used for the high voltage DC output in the slow charging mode of the vehicle charger 22, converting AC power into DC power suitable for high voltage charging of the battery.

[0040] Please also read Figure 2 , Figure 3 and Figure 5 In one embodiment, the third side plate 124 is provided with a liquid inlet 1245 and a liquid outlet 1246 which are arranged at intervals, and the vehicle-mounted integrated power supply controller 100 further includes a three-dimensional water channel 30, which is arranged in a surrounding manner in the accommodating cavity 11, and one end of the three-dimensional water channel 30 is connected to the liquid inlet 1245, and the other end is connected to the liquid outlet 1246. The three-dimensional water channel 30 is used to transport cooling medium to cool the vehicle-mounted charger 22, the voltage converter 23, the vehicle-mounted heater control chip 24 and the vehicle-mounted compressor control chip 25 in the accommodating cavity 11. Through the above arrangement, the three-dimensional water channel 30 is arranged in a surrounding manner inside the accommodating cavity 11 to form a three-dimensional cooling environment, ensuring that the cooling medium can cover the key heating components in the entire accommodating cavity 11. Among them, the liquid inlet 1245 is used to introduce cooling medium (such as water or coolant), and the liquid outlet 1246 is used to discharge the cooling medium that has absorbed heat. The cooling medium flows in the three-dimensional water channel 30, absorbing heat from various heating elements, especially key components such as the on-board charger 22, the voltage converter 23, the heater control chip and the compressor control chip, thereby dissipating the heat of the entire on-board integrated power controller 100 and improving the product reliability of the on-board integrated power controller 100.

[0041] Please continue reading Figure 2 , Figure 3 and Figure 5In one embodiment, the three-dimensional water channel 30 is a U-shaped structure, and the three-dimensional water channel 30 includes a first cooling segment 31, a second cooling segment 32 and a third cooling segment 33. The first cooling segment 31 and the second cooling segment 32 are spaced apart along the third direction Y, and the third cooling segment 33 is connected between the first cooling segment 31 and the second cooling segment 32. The first cooling segment 31, the second cooling segment 32 and the third cooling segment 33 are surrounded to form a cooling cavity 34. Among them, the liquid inlet 1245 is connected to one end of the first cooling segment 31 away from the third cooling segment 33, and the liquid outlet 1246 is connected to one end of the second cooling segment 32 away from the third cooling segment 33.

[0042] Specifically, the first cooling section 31, the second cooling section 32 and the third cooling section 33 form a closed-loop cooling system. The U-shaped structure design increases the contact area between the cooling medium and the heating element, thereby improving the heat exchange efficiency and cooling effect. The U-shaped structure ensures that the cooling medium fully circulates in the accommodating cavity 11, covers all key heating elements, and provides efficient heat exchange.

[0043] In the actual cooling process, the first cooling section 31 serves as the introduction section of the cooling medium, and the low-temperature cooling medium enters the first cooling section 31 from the liquid inlet 1245 and begins to absorb heat. The second cooling section 32 serves as the discharge section of the cooling medium. After sufficient heat absorption, the high-temperature cooling medium flows from the second cooling section 32 to the liquid outlet 1246 and is discharged from the system. The third cooling section 33 serves as the transition section of the cooling medium, connecting the first cooling section 31 and the second cooling section 32 to ensure that the cooling medium can flow smoothly between the two cooling sections. It can be understood that the third cooling section 33 itself also participates in heat exchange, especially in the high-temperature area between the first cooling section 31 and the second cooling section 32, thereby further improving the cooling efficiency.

[0044] In one embodiment, the first cooling segment 31 , the second cooling segment 32 and the third cooling segment 33 are an integrally formed structure, thereby improving the structural strength of the three-dimensional water channel 30 .

[0045] Please continue reading Figure 2 , Figure 3 and Figure 5 In one embodiment, the vehicle-mounted integrated power controller 100 further includes a main transformer 40, a sub-transformer 50 and a circuit inductor 60. The main transformer 40 is disposed in the cooling cavity 34 and is adjacent to the third cooling section 33. The sub-transformer 50 is disposed in the cooling cavity 34 and is spaced apart on the side of the main transformer 40 away from the third cooling section 33. The circuit inductor 60 is disposed in the cooling cavity 34 and is disposed between the main transformer 40 and the sub-transformer 50. Through the above arrangement, the main transformer 40, the sub-transformer 50 and the circuit inductor 60 are disposed in the cooling cavity 34, so that while the three-dimensional water channel 30 cools them, it can also make full use of the space in the accommodating cavity 11 to improve space utilization.

[0046] Specifically, the main transformer 40 is responsible for converting the input high-voltage direct current into low-voltage direct current suitable for use by each module, such as the on-board charger 22, the voltage converter 23, etc. The auxiliary transformer 50 is mainly used for the voltage conversion requirements of auxiliary circuits or specific modules, such as providing a stable power supply for control systems or other low-power devices. In some application scenarios, the auxiliary transformer 50 can be used as a backup power supply to ensure that the system can still operate normally when the main transformer 40 fails, thereby improving the reliability and fault tolerance of the system. The circuit inductor 60 is used to filter out high-frequency noise in the current, smooth the output current, and store energy when necessary to ensure the stability of the output voltage.

[0047] Please continue reading Figure 2 , Figure 3 and Figure 5 In one embodiment, the vehicle-mounted integrated power controller 100 further includes a thermally conductive adhesive (not shown), which is connected between the main transformer 40 and the wall of the cooling cavity 34, between the auxiliary transformer 50 and the wall of the cooling cavity 34, and between the circuit inductor 60 and the wall of the cooling cavity 34. Through the above arrangement, the thermally conductive adhesive fills the tiny gap between the heating element (i.e., the main transformer 40, the auxiliary transformer 50, and the circuit inductor 60) and the wall of the cooling cavity 34, ensuring that the heat can be evenly distributed and reducing the risk of local overheating. The thermally conductive adhesive not only provides a heat conduction path, but also plays a role in mechanical fixation, firmly adhering the heating element to the wall of the cooling cavity 34, reducing the risk of vibration and displacement.

[0048] In one embodiment, the MOSFET (power MOS field effect transistor) of the vehicle charger 22, the voltage converter 23, the vehicle heater control chip 24, and the vehicle compressor control chip 25 are all integrated on a power board (not shown). The power board is integrated and arranged vertically in the accommodating cavity 11. Through the above arrangement, the vertically arranged power board makes full use of the limited space in the accommodating cavity 11, reduces the horizontal occupied area, and realizes a more integrated power supply system.

[0049] In one embodiment, the power board and the circuit board 20 are connected by a custom plug-in (not shown), and the power board is close to the three-dimensional water channel 30, thereby reducing the layout volume. The layout of the three-dimensional water channel 30 ensures thermal isolation between the power modules on the power board, avoids local hot spots, and improves the stability of the power system.

[0050] Please also read Figure 2 and Figure 3 In one embodiment, the vehicle-mounted integrated power controller 100 further includes an AC electromagnetic board 70, which is welded to the circuit board 20 to ensure the stability and reliability of the electrical connection. The AC electromagnetic board 70 is mainly used to suppress electromagnetic interference (EMI) from the input AC power to ensure that clean AC power enters the system.

[0051] Please continue reading Figure 2 and Figure 3 In one embodiment, the vehicle-mounted integrated power controller 100 also includes a DC electromagnetic board 80, and the AC electromagnetic board 70 is welded together with the circuit board 20 to ensure the stability and reliability of the electrical connection. The DC electromagnetic board 80 is used for filtering the high-voltage DC output.

[0052] Please continue reading Figure 2 and Figure 3 In one embodiment, the vehicle-mounted integrated power controller 100 also includes a low-voltage filter 90, which is welded to the circuit board 20 to ensure the stability and reliability of the device. The low-voltage filter 90 is used to filter the output of the low-voltage direct current.

[0053] Please continue reading Figure 2 and Figure 3 In one embodiment, the vehicle-mounted integrated power controller 100 further includes a plurality of aluminum substrates 101, which are used to install switch circuits (i.e., power factor correction components, PFC circuits, Power Factor Correction), filter circuits (LC circuits), vehicle-mounted compressors, and MOS tubes (i.e., power transistors) of vehicle-mounted heaters. The MOS tubes are all reflow-welded onto the aluminum substrates 101, and attached to the three-dimensional water channel 30 through thermal conductive adhesive for heat dissipation. At the same time, the aluminum substrates 101 can be welded to the circuit board 20 through an adapter plug-in. By rationally arranging the positions of the components, the limited space can be fully utilized, and the overall volume can be reduced, which is particularly suitable for in-vehicle installation.

[0054] Please also read Figure 2 and Figure 6 The present application also provides a vehicle 200, comprising the above-mentioned vehicle-mounted integrated power supply controller 100.

[0055] The above-mentioned vehicle integrated power controller 100 is one of the core components of the vehicle 200, responsible for managing the power distribution and conversion of the vehicle 200, integrating multiple modules such as the vehicle charger 22, the voltage converter 23, the vehicle heater control chip 24, and the vehicle compressor control chip 25, to achieve compact design and efficient management. At the same time, the microprocessor chip 21 coordinates the operation of each module to ensure the efficient operation of the entire system, and dynamically adjusts the working status of each module according to real-time needs.
