[0088] The fourth circulation loop is connected in sequence to the compressor 2036, the second heat exchanger 2022, the condenser 2037, the third control valve 2013, and the gas-liquid separator 2038. The fourth control valve 2014 and the first heat exchanger 2021 are connected in parallel to the second heat exchanger 2022 and the gas-liquid separator 2038. The fourth circulation loop is also connected to the evaporator 2039, which is connected between the fourth control valve 2014 and the gas-liquid separator 2038.

[0089] The following is Figures 3-13 Taking an example, the operation of the vehicle thermal management system control method in the embodiment of the present invention will be described in detail.

[0090] like Figure 3 As shown, to achieve compressor-based heating of the passenger compartment via an air source, the method is as follows: The third control valve 3013 is connected, and the fourth control valve 3014 is closed. Heat exchange occurs between the first and fourth circulation loops. In the fourth circulation loop, the compressor 3036 obtains heat from the air, which is then input into the first circulation loop via the second heat exchanger 3023, and then returns to the compressor 3036 via the condenser 3037, the third control valve 3013, and the gas-liquid separator 3038 to complete the cycle. In the first circulation loop, heat is obtained through the second heat exchanger 3022, input into the third heat exchanger 3023, and then input into the passenger compartment, thus achieving compressor-based heating of the passenger compartment via an air source.

The first and fourth circulation loops exchange heat. In the second circulation loop, heat is input from the electric drive 4033 via end 3 and output from end 2 of the first control valve 4011. The heat is then output through the first heat exchanger 4021 and flows back to the electric drive 4033 to complete the cycle. In the fourth circulation loop, heat is output from the first heat exchanger 4021, passes through the gas-liquid separator 4038 and compressor 4036, and then output through the second heat exchanger 4022. In the first circulation loop, heat is obtained through the second heat exchanger 4022 and input to the third heat exchanger 4023, from which it is input to the passenger compartment, thus achieving heating of the passenger compartment using electrically driven waste heat.

[0092] like Figure 5As shown, to achieve heating of the passenger compartment using air source and electrically driven waste heat, the method is as follows: connect the third control valve 5013, connect the fourth control valve 5014, connect the second and third ends of the first control valve 5011, and so on. Figure 4 As shown, the second circulation loop outputs heat to the fourth circulation loop. In the first circulation loop, heat is obtained through the second heat exchanger 5022 and input to the third heat exchanger 5023. In the fourth circulation loop, heat is output by the first heat exchanger 5021 and the compressor 5036 and input to the crew compartment through the third heat exchanger 5023, thereby realizing the heating of the crew compartment through the air source and the waste heat driven by electricity.

[0093] It should be noted that when there is no need for heating by the waste heat of the electric drive, the electric drive 5033 dissipates heat to the low-temperature heat sink 5034 via the second circulation loop.

In the first circulation loop, heat is obtained through the second heat exchanger 6022 and input to the third heat exchanger 6023, from which it is input to the passenger compartment, thus achieving battery heat dissipation and utilizing battery waste heat to heat the passenger compartment.

[0095] like Figure 7 As shown, to achieve heating of the passenger compartment using waste heat from the battery and the electric drive, the method is as follows: The third control valve 7013 is closed, the fourth control valve 7014 is connected, the second and third ends of the first control valve 7011 are connected, and the first and third ends of the second control valve 7012 are connected. The electric drive 7033 outputs heat to the first heat exchanger 7021, and the battery 7035 outputs heat to the first heat exchanger 7021 through the third circulation loop. In the fourth circulation loop, heat is output from the first heat exchanger 7021, passing through the gas-liquid separator 7038 and the compressor 7036 before being output to the second heat exchanger 7022. In the first circulation loop, heat is obtained through the second heat exchanger 7022 and input to the third heat exchanger 7023, from which it is input to the passenger compartment, thus achieving heating of the passenger compartment using waste heat from the battery and the electric drive.

[0096] Depend on Figure 5 , Figure 6 and Figure 7As can be seen from the solution, the vehicle thermal management system provided in this embodiment can achieve the function of heating the battery while heating the passenger compartment, and can shield the battery when the waste heat from the electric drive heats up the passenger compartment.

In the third circulation loop, the battery 9035 is cooled by the first heat exchanger 9021, thus achieving refrigeration and dehumidification of the crew cabin and battery cooling.

[0099] like Figure 10 As shown, to achieve refrigeration, dehumidification, and battery heating in the crew cabin, the following method is used: The third control valve 10013 is connected, the fourth control valve 10014 is connected, the first and third ends of the first control valve 10011 are connected, and the first and second ends of the second control valve 10012 are connected. In the fourth circulation loop, the evaporator 10039 is cooled via the second heat exchanger 10022 and / or the condenser 10037. Simultaneously, in the first circulation loop, the second heat exchanger 10022 outputs heat to the fourth heat exchanger 10024, thus achieving refrigeration, dehumidification, and battery heating in the crew cabin.

In the fourth circulation loop, the evaporator 11039 is cooled via the second heat exchanger 11022 and / or the condenser 11037. At the same time, the electric drive 11033 outputs heat to the first heat exchanger 11021, which outputs heat to the second heat exchanger 11022, and then the third heat exchanger 11023 heats the crew cabin, thereby achieving heating and dehumidification of the crew cabin.

[0101] like Figure 12As shown, to achieve heating, dehumidification, and battery cooling in the crew compartment, the method is as follows: close the third control valve 12013, connect the fourth control valve 12014, connect the first and third ends of the first control valve 12011, and connect the first and third ends of the second control valve 12012.
