[0036] In a first aspect, the present application provides a thermal management system, thereby solving the problem that the components in the existing thermal management system themselves all include a controller PCBA, however, these PCBAs are scattered, have low integration, and are complex and difficult to debug and repair.

[0037] Refer to the following Figures 1 to 3 The thermal management system according to some embodiments of the present application is described in detail.

[0038] like Figure 1 As shown, the thermal management system of the present application includes a thermal management domain controller, a plurality of low-voltage drive components and a plurality of high-voltage drive components; wherein the thermal management domain controller includes a low-voltage controller 100 and a high-voltage controller 200. wherein each low-voltage drive component includes a low-voltage control part and a low-voltage mechanical part, and each low-voltage control part is integrated in the low-voltage controller 100; each high-voltage drive component includes a high-voltage control part and a high-voltage mechanical part, and each high-voltage control part is integrated in the high-voltage controller 200. wherein the low-voltage controller 100 includes a low-voltage power supply interface, a first signal interface and a low-voltage drive interface; the first signal interface is used to connect the overall control system of the whole vehicle, the low-voltage power supply interface is used to connect the power supply of the whole vehicle, and the low-voltage drive interface is used to connect the low-voltage mechanical part. similarly, the high-voltage controller 200 includes a high-voltage power supply interface, a second signal interface and a high-voltage drive interface; the second signal interface is used to connect the overall control system of the whole vehicle, the high-voltage power supply interface is used to connect the power supply of the whole vehicle, and the high-voltage drive interface is used to connect the high-voltage mechanical part.

[0039] According to the above technical features, the beneficial effects of this application are:

[0040] The thermal management domain controller of the present application includes a low-voltage controller 100 and a high-voltage controller 200. Among them, the control parts of the low-voltage driving components in the thermal management system are all integrated into the low-voltage controller 100 (the control part is the controller / control circuit), and only the mechanical part is retained; and the power supply of the whole vehicle is connected to the low-voltage power supply interface of the low-voltage controller 100 to power the low-voltage controller 100, the overall control system of the whole vehicle is connected to the first signal interface of the low-voltage controller to achieve communication connection with the low-voltage controller, and the low-voltage mechanical part is connected to the low-voltage driving interface of the low-voltage controller to be uniformly controlled by the low-voltage controller (the same applies to the high-voltage controller 200).

[0041] In summary, the control parts of the low-voltage drive components in the thermal management system of the present application are all integrated into the low-voltage controller 100, and only the mechanical parts are retained, and the mechanical parts of the low-voltage drive components are uniformly controlled by the low-voltage controller 100 (the same applies to the high-voltage controller 200). Therefore, the control part of the low-voltage drive component / the control part of the high-voltage drive component (original controller) of the present application has a high degree of integration, and all subsequent debugging and troubleshooting after control integration are mainly located in the thermal management domain controller, which greatly facilitates product debugging and maintenance work.

[0042] The structure of the low voltage controller 100 will be described in detail below.

[0043] In the embodiments of the present application, Figure 2 As shown, multiple low-voltage drive components include a blower 14 (brushless motor, 450w), a low-voltage heater 15 (resistance heater, 1kw), a cooling fan 16 (brushless motor, 450w-600w), a motor water pump 17 (brushless motor, ≤150w), a battery water pump 18 (brushless motor, ≤150w), a heater water pump 19 (brushless motor, ≤90w), a first electronic expansion valve 20 (stepping motor, a second electronic expansion valve 21 (stepping motor, a third electronic expansion valve 22 (stepping motor).

[0044] Furthermore, the low-voltage controller 100 of the present application is internally composed of 4 or 6 layers of PCB boards, and integrates a control circuit ( Figure 2 In the embodiment, only the mechanical parts of the blower 14, the low-pressure heater 15, the cooling fan 16, the motor water pump 17, the battery water pump 18, the heater water pump 19, the first electronic expansion valve 20, the second electronic expansion valve 21, and the third electronic expansion valve 22 are retained).

[0045] In the embodiments of the present application, Figure 1 As shown, the low voltage controller 100 includes a first low voltage connector 5 and a second low voltage connector 6. The first low voltage connector 5 and the second low voltage connector 6 each include a plurality of pins, and among the plurality of pins of the first low voltage connector 5 or the second low voltage connector 6, some pins are first signal interfaces, and some pins are low voltage drive interfaces.

[0046] Optionally, the low voltage controller 100 further includes a third low voltage connector 3 and a fourth low voltage connector 4, and the third low voltage connector 3 and the fourth low voltage connector 4 are used for connection of high power low voltage driving components.

[0047] For example, the low-pressure mechanical part of the blower 14 can be connected to the third low-pressure connector 3, and the low-pressure mechanical part of the cooling fan 16 can be connected to the fourth low-pressure connector 4; the low-pressure mechanical parts of the low-pressure heater 15, multiple water pumps and multiple electronic expansion valves can be connected to the first low-pressure connector 5 or the second low-pressure connector 6.

[0048] For example, the vehicle can be connected to the first low-voltage connector 5 or the second low-voltage connector 6 through a wiring harness (CAN bus) to realize the communication connection between the overall control system of the vehicle and the low-voltage controller 100. The low-voltage controller 100 inputs the control signal of the overall control system of the vehicle (VDCU or HMI controller) and outputs the control drive signal of each low-voltage drive component. In addition, the power supply of the vehicle is connected to the positive power supply connector 1 and the negative power supply connector 2 through a wiring harness to input the low-voltage platform voltage of the vehicle.

[0049] Further, in the embodiments of the present application, Figure 2 As shown, the thermal management system also includes a damper motor 23 (mechanical part), a two-way valve 27 (mechanical part), a five-way valve 26 (mechanical part), an air duct temperature sensor 24, an evaporator temperature sensor 25, two pressure temperature sensors, a refrigerant temperature sensor 30, a water temperature sensor 31 and a liquid level sensor 32.

[0050] Correspondingly, the low-pressure controller 100 also includes the interface circuits of the damper motor 23, the two-way valve 27, the five-way valve 26, the air duct temperature sensor 24, the evaporator temperature sensor 25, two pressure temperature sensors (a first pressure temperature sensor 28, a second pressure temperature sensor 29), the refrigerant temperature sensor 30, the water temperature sensor 31 and the liquid level sensor 32.

[0051] like Figure 1 As shown, the damper motor 23, the two-way valve 27, the five-way valve 26, the duct temperature sensor 24, the evaporator temperature sensor 25, two pressure temperature sensors, the refrigerant temperature sensor 30, the water temperature sensor 31 and the liquid level sensor 32 can be connected to the first low-voltage connector 5 or the second low-voltage connector 6.

[0052] The low voltage controller 100 inputs the control signal of the overall control system of the vehicle (VDCU or HMI controller), receives the signal of each sensor at the same time, and performs data calculation, and can output the control drive signal of each low voltage drive component according to the calculation result.

[0053] The structure of the high voltage controller 200 will be described in detail below.

[0054] In the embodiments of the present application, Figure 3 As shown, the plurality of high voltage drive components include a compressor 33 (a high voltage brushless motor) and a high voltage heater 34 (a resistance type heater).

[0055] Furthermore, the interior of the high-voltage controller 200 of the present application is composed of 2 or 4 layers of PCB boards, which integrate the control circuit including the compressor 33 and the high-voltage heater 34 ( Figure 3 In the example, only the mechanical parts of the compressor 33 and the high-pressure heater 34 are retained).

[0056] In the embodiments of the present application, Figure 1 As shown, the second signal interface and the high-voltage drive interface are both high-voltage connectors. For example, the high-voltage mechanical part of the compressor 33 can be connected to the second high-voltage connector 9, and the high-voltage mechanical part of the high-voltage heater 34 can be connected to the third high-voltage connector 10 and the fourth high-voltage connector 11.

[0057] For example, the vehicle can be connected to the first high-voltage connector 7 through a wiring harness (CAN bus) to realize the communication connection between the overall control system of the vehicle and the high-voltage controller 200. The high-voltage controller 200 inputs the control signal of the overall control system of the vehicle (VDCU or HMI controller) and outputs the control drive signal of each high-voltage drive component. In addition, the power supply of the vehicle is connected to the high-voltage power supply connector 8 through a wiring harness to input the high-voltage platform voltage of the vehicle.

[0058] In addition, in the embodiments of the present application, Figure 1 As shown, the thermal management system also includes a flow channel plate 300, which is arranged between the low-voltage controller 100 and the high-voltage controller 200. A serpentine flow channel is arranged inside the flow channel plate 300, and a liquid inlet 301 and a liquid outlet 302 are formed at both ends of the flow channel, respectively, and the coolant flows through the external liquid inlet 301 and the liquid outlet 302. In this way, the sandwich design of the middle heat dissipation flow channel plate 300 not only realizes the EMC isolation of the high and low voltage PCBA boards, but also achieves the cooling and heat dissipation of the high-temperature components on the high and low voltage PCBAs through the middle heat dissipation flow channel plate 300.

[0059] In this example, the flow channel plate 300 and the housing of the low-pressure controller 100 and the housing of the high-pressure controller 200 can be an integrated metal forming design.

[0060] In addition, it is worth mentioning that the mechanical parts of the multiple water pumps and multiple electronic expansion valves of the present application can be integrated with the thermal management domain controller into an integral module. In this way, after being integrated into an integral module, the distance between the various electrical components is reduced, and the connection and control of the thermal management electrical components can achieve the shortest electrical circuit, the least wiring harness, the smallest control error, and the lowest development and design cost.

[0061] In summary, the control parts of the low-voltage drive components in the thermal management system of the present application are all integrated into the low-voltage controller 100, and only the mechanical parts are retained, and the mechanical parts of the low-voltage drive components are uniformly controlled by the low-voltage controller 100 (the same applies to the high-voltage controller 200). Therefore, the control part of the low-voltage drive component / the control part of the high-voltage drive component (original controller) of the present application has a high degree of integration, and all subsequent debugging and troubleshooting after control integration are mainly located in the thermal management domain controller, which greatly facilitates product debugging and maintenance work.

[0062] In summary, the thermal management domain controller of the present application integrates the thermal management low-voltage parts and high-voltage parts into hardware and software. The thermal management domain controller realizes the interaction with the thermal management signal of the whole vehicle by connecting to the CAN communication signal of the whole vehicle. At the same time, through the thermal management logic of the thermal management domain controller itself and the internal component drive circuit, it is converted into the corresponding control drive signal to the external thermal management parts to drive the parts to operate. Compared with the current industry method of connecting to thermal management parts in different positions through a large number of wire harnesses, the electrical interfaces on the whole vehicle can be more concentrated and fewer. At the same time, the thermal management domain controller can be assembled on the thermal management integrated module. For the connection and control of electrical components of thermal management, the electrical circuit can be shortest, the wire harness is the least, the control error is the smallest, and the development and design cost is the lowest.

[0063] In summary, the design of the thermal management domain controller is based on a platform design, so the same thermal management domain controller can be provided for different new energy vehicle models, and the hardware design is compatible. In terms of software, for specific models, only the parameters of the software part need to be updated according to the specific environmental model and road test parameters of the vehicle. In this way, compared with the current development of new energy thermal management system electrical, the thermal management domain controller for new energy vehicles can reduce the use of vehicle thermal management parts and wiring harnesses by nearly 70%; for the development of thermal management parts, only the mechanical part needs to be developed, and the development cost of parts will be reduced by nearly 60%; for the development of thermal management systems, a platform product can be compatible with the development and design of different models, and with the thermal management integrated module, the thermal management system can be fully platformized, and the system control development and design costs will be saved by nearly 50%.

[0065] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application rather than to limit them. The protection scope of the present application is not limited thereto.
