[0062] In an embodiment of the present utility model, the liquid outlet of the cabin 9 is connected to the liquid inlet of the auxiliary drive controller 3 .

[0063] In a specific implementation, the liquid outlet of the cabin 9 can be connected to the liquid inlet of the auxiliary drive controller 3 , so that the temperature of the cabin 9 and the drive motor 1 can be controlled simultaneously through the second radiator 7 .

[0067] The second electronic water pump 19 has a liquid outlet connected to a liquid inlet of the second water heating resistor 17 .

[0068] In a specific implementation, since the cabin 9 may have a stronger heating demand when the temperature is low, a heater chip 14 may be provided, and a second water heating resistor 17 and a second electronic water pump 19 are connected to the vehicle temperature control system, the liquid outlet of the heater chip 14 is connected to the liquid inlet of the cabin 9, the liquid outlet of the second water heating resistor 17 is connected to the liquid inlet of the heater chip 14, and the liquid outlet of the second electronic water pump 19 is connected to the liquid inlet of the second water heating resistor 17; wherein the second water heating resistor may also be a water heating PTC (Positive Temperature Coefficient thermistor), thereby satisfying the additional heating demand of the cabin 9 by providing an additional heating circuit.

[0069] In an embodiment of the present utility model, a fifth stop valve 20 is connected to the liquid inlet end of the second electronic water pump 19 .

[0070] In practical applications, the start-up control of the second electronic water pump 19 can be achieved by additionally providing a fifth stop valve 20 .

[0071] In an embodiment of the present invention, the cabin 9 at least includes a first area, a second area, a third area, and a fourth area.

[0072] In a specific implementation, the interior of the cabin 9 can be divided into a first area A, a second area B, a third area C, and a fourth area D, so that corresponding temperature control can be performed according to actual temperature requirements of different areas.

[0073] In an embodiment of the present utility model, the first area, the second area, the third area and the fourth area are respectively connected to the liquid outlet end of the second stop valve 8 through a hose.

[0074] In practical applications, the first area, the second area, the third area, the fourth area and the second stop valve 8 can be connected through a hose, so that the temperature of the first area, the second area, the third area and the fourth area can be controlled through the second stop valve 8.

[0075] In an embodiment of the present invention, the first area, the second area, the third area and the fourth area are respectively connected to the temperature sensor 21 .

[0076] In a specific implementation, the actual temperature information of the first area, the second area, the third area and the fourth area can be detected respectively by the temperature sensor 21, so that the temperature of the first area, the second area, the third area and the fourth area can be controlled accordingly according to the actual temperature information.

[0077] Based on the above, when the temperature of the drive motor 1, the power battery 12 and the ambient cabin 9 is too high and needs to be cooled, the Figure 1 Part of the structure of the vehicle temperature control system shown meets the corresponding requirements, specifically, Figure 2 As shown, the coolant can be divided into three branches from the first electronic water pump 4 to cool the drive motor 1, the power battery 12 and the cabin 9 respectively.

[0078] First branch: the coolant can flow through the auxiliary drive controller 3 , the drive motor controller 2 and the drive motor 1 via the high-temperature radiator 5 and the first stop valve 6 , thereby reducing the temperature of the drive motor 1 and the drive motor controller 2 .

[0079] Second branch: The coolant can start from the first electronic water pump 4, flow through the low-temperature radiator 7 and the second stop valve 8 connected in parallel, and further flow through the cabin 9, the auxiliary drive controller 3, the drive motor controller 2 and the drive motor 1, so as to reduce the temperature of the cabin 9 and the drive motor 1. The temperature sensor 21 can be used to detect the temperature of the four areas divided by the cabin 9 respectively, and the second electronic valve 8 can be used to control the coolant flow in the hose to perform local or overall heat dissipation on the area in the cabin 9 that needs to be cooled.

[0080] The third branch: The coolant can start from the first electronic water pump 4, flow through the low-temperature radiator 7 connected in parallel, the third stop valve 10 and flow through the power battery 12, thereby reducing the temperature of the power battery 12. The refrigerant can be discharged through the electric compressor 18, flow through the air-cooled condenser 15 and further flow through the fourth stop valve 16 to the heat exchanger 13. The heat exchanger 13 can absorb the heat of the coolant through the refrigerant, so that the temperature of the coolant in the power battery 12 is reduced, thereby reducing the temperature of the power battery.

[0081] Further, such as Figure 3 As shown, when the temperature of the drive motor 1 and the power battery 12 is too high and needs to be cooled, the coolant can be divided into two branches from the first electronic water pump 4 to cool the drive motor 1 and the power battery 12 respectively.

[0082] First branch: the coolant can further flow through the auxiliary drive controller 3, the drive motor controller 2 and the drive motor 1 after flowing through the high-temperature radiator 5 and the first stop valve 6, thereby reducing the temperature of the drive motor 1 and the drive motor controller 2.

[0083] Second branch: The coolant can start from the first electronic water pump 4, flow through the low-temperature radiator 7, the third stop valve 10 and the power battery 12 connected in parallel, so as to reduce the temperature of the power battery 12. The refrigerant can be discharged through the electric compressor 18, flow through the air-cooled condenser 15, and then flow through the fourth stop valve 16 to reach the heat exchanger 13. The heat exchanger 13 can absorb the heat of the coolant through the refrigerant, so that the temperature of the coolant in the power battery 12 is reduced, thereby reducing the temperature of the power battery.

[0084] Further, such as Figure 4 As shown, when the temperature of the drive motor 1 is too high and needs to be cooled, but the temperature of the power battery 12 and the cabin 9 is low and needs to be heated, the coolant can be divided into two branches from the first electronic water pump 4 to cool the drive motor 1 respectively, and the waste heat can be used to heat the power battery 12 and the cabin 9; specifically:

[0085] First branch: The coolant can flow out from the first electronic water pump 4, flow through the low-temperature radiator 7, the second stop valve 8 and the cabin 9, and further flow through the auxiliary drive controller 3 and the drive motor controller 2 in sequence to reach the drive motor 1, thereby cooling the drive motor 1 and heating the cabin 9. The temperature sensor 21 can be used to detect the temperatures of the four areas divided by the cabin 9 respectively, and locally or entirely heat the areas in the cabin 9 that need to be heated.

[0086] Second branch: the coolant can flow out from the first electronic water pump 4 , flow through the low-temperature radiator 7 and the third stop valve 10 to the first water heating resistor 11 , and further flow through the power battery 12 , thereby achieving the temperature increase of the power battery 12 .

[0087] Further, such as Figure 5 As shown, when the waste heat of the drive motor 1 is insufficient to make the cabin 9 reach the target temperature, the coolant can start from the second electronic water pump 19, flow through the second water heating resistor 17 and the heater chip 14 for heating, and then reach the cabin 9 for heating. The temperature sensor 21 can be used to detect the temperature of the four areas divided by the cabin 9 respectively, and the second electronic valve 8 can control the flow of the coolant in the hose, so as to locally or overall heat the area in the cabin 9 that needs to be heated, so that the cabin 9 reaches the target temperature and meets the actual use requirements.
