[0016] Another aspect of the present application provides an integrated thermal management system. Figure 1 A schematic diagram of the structure of an integrated thermal management system provided by an embodiment of the present application is shown.

[0022] Figure 3 A schematic diagram of the structure of a six-way valve integrated module provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the six-way valve integrated module 12 integrates: a six-way valve 21, two water tanks 22 and two water pumps 23. The two water tanks 22 are respectively a first water tank 22a and a second water tank 22b, and the two water pumps 23 are respectively a first water pump 23a and a second water pump 23b.

[0024] The six-way valve 21 includes a housing, a driving mechanism, a valve core and six interface pipes. Specifically, the six interface pipes are arranged on the housing. The valve core is arranged in the housing to divide the housing cavity into a plurality of small cavities, each of which is connected to two interface pipes.

[0028] Figure 4 A schematic diagram of the structure of another integrated thermal management system provided in an embodiment of the present application is shown. Figure 4 The controller 11 is not identified.

[0029] like Figure 4 As shown, the six interface pipes of the six-way valve are a first interface pipe A, a second interface pipe B, a third interface pipe C, a fourth interface pipe D, a fifth interface pipe E and a sixth interface pipe F respectively.

[0030] The six interface pipes of the six-way valve 21 are respectively connected to the battery circuit 13, the heating circuit 14 and the heat exchange circuit 15 and may include: a first interface pipe A is connected to the input pipe opening of the heat exchange circuit. A second interface pipe B is connected to the input pipe opening of the battery circuit 13. A third interface pipe C is connected to the output pipe opening of the battery circuit. A fourth interface pipe E is connected to the output pipe opening of the heating circuit 14. A fifth interface pipe F is connected to the output pipe opening of the heat exchange circuit 15.

[0031] like Figure 4As shown, the battery circuit 13 includes a battery 131 , and the battery circuit 13 can be used to cool or heat the battery 131 through a coolant in the circuit.

[0032] The first water pump 23a and the first water tank 22a are connected in series in the battery circuit, and the connection relationship is: one pipe port of the battery 131 is connected to the second interface pipe B, the other pipe port of the battery 131 is connected to the input pipe port of the first water tank 22a, the output pipe port of the first water tank 22a is connected to the input pipe port of the first water pump 23a, and the output pipe port of the first water pump 23a is connected to the third interface pipe C. Among them, the output pipe port of the first water pump 23a can be used as the output pipe port of the battery circuit 13.

[0033] It should be noted that one pipe opening of the battery 131 is connected to the second interface pipe B through a water pipe, and the pipe opening connected to the second interface pipe B can be used as the input pipe opening of the battery circuit 13. Another pipe opening of the battery 131 is connected to the first water tank 22a through a water pipe.

[0034] like Figure 4 As shown, the heat exchange loop 15 includes a heat exchanger 151. The heat exchanger 151 includes four pipe openings, namely a first pipe opening G, a second pipe opening H, a third pipe opening I and a fourth pipe opening J. The first pipe opening G is connected to the first interface pipe opening A, the second pipe opening H is connected to the fifth interface pipe E, the third pipe opening I is connected to the input pipe opening of the air conditioning loop 16, and the fourth pipe opening J is connected to the output pipe opening of the air conditioning loop 16.

[0035] It should be noted that the first pipe opening G is connected to the first interface pipe opening A through a water pipe, and the pipe opening connected to the first interface pipe opening A can be used as the output pipe opening of the heat exchange circuit 15. The second pipe opening H is connected to the fifth interface pipe E through a water pipe, and the pipe opening connected to the fifth interface pipe E can be used as the input pipe opening of the heat exchange circuit 15.

[0036] like Figure 4 As shown, the heating circuit 14 is used to heat the coolant in the circuit. The heating circuit 14 includes a water heater 141 and a warm air core 142. The water heater 141 can be a device that can quickly heat the liquid. The warm air core 142 is used to generate hot air based on the coolant in the circuit and introduce it into the passenger compartment.

[0037] The second water pump 23b and the second water tank 22b are connected in series in the heating circuit 14, and the connection relationship includes: the input pipe port of the second water tank 22b is connected to the sixth interface pipe F, the output pipe port of the second water tank 22b is connected to the input pipe port of the second water pump 23b, the output pipe port of the second water pump 23b is connected to a pipe port of the water heater 141, the other pipe port of the water heater 141 is connected to a pipe port of the warm air core 142, and the other pipe port of the warm air core 142 is connected to the fourth interface pipe D.

[0038] After receiving the passenger compartment heating request, the integrated thermal management system will switch to the appropriate thermal management circuit according to the battery temperature to provide heat for the passenger compartment. In some embodiments, the control instruction includes a first passenger compartment heating instruction and a second passenger compartment heating instruction. The first passenger compartment heating instruction and the second passenger compartment heating instruction are both passenger compartment heating instructions. The passenger compartment heating instruction may be an instruction to implement the passenger compartment heating function, that is, an instruction to control the integrated thermal management system to implement the passenger compartment heating mode in the thermal management mode. Among them, the first passenger compartment heating instruction is used to instruct the use of the water heater 141 to heat the passenger compartment. The second passenger compartment heating instruction is used to instruct the use of battery waste heat to heat the passenger compartment.

[0039] In some of the embodiments, the controller 11 is used to start the heater core and the water heater when receiving a passenger compartment heating request and the battery temperature does not exceed the first preset temperature, so that the heating circuit 14 is in a heating state, and send a first passenger compartment heating instruction to the six-way valve;

[0040] The six-way valve 21 is used to control the driving mechanism to drive the valve core to rotate according to the first passenger compartment heating instruction, connecting the fourth interface pipe D and the sixth interface pipe F to connect the heating circuit to form the first passenger compartment heating circuit corresponding to the first passenger compartment heating mode.

[0041] The battery temperature involved in the embodiment of the present application refers to the current temperature of the battery 131. The first preset temperature can be set according to the vehicle design, battery characteristics and safety standards, and is used to measure whether the battery has excess heat. Optionally, the first preset temperature can be 40 degrees.

[0042] In one embodiment of the present application, after receiving the passenger compartment heating request, the controller 11 determines whether the battery temperature exceeds the first preset temperature. When the battery temperature does not exceed the first preset temperature, that is, the battery 131 cannot provide heat to the passenger compartment, the controller 11 starts the heater core 142 and the water heater 141, and sends a first passenger compartment heating instruction to the six-way valve 21.

[0043] It should be noted that the passenger compartment heating request may be generated by a user's operation on the control panel or may be automatically generated when the temperature of the passenger compartment is at a relatively low temperature.

[0044] In addition, the controller 11 also starts the second water pump 23b. After receiving the first passenger compartment heating instruction sent by the controller 11, the six-way valve 21 controls the valve core position by rotating the driving mechanism, so that the fourth interface pipe D is connected to the sixth interface pipe F, so that the input pipe port and the output pipe port of the heating circuit 14 are connected, forming a first passenger compartment heating circuit corresponding to the first passenger compartment heating mode.

[0045] In the first passenger compartment heating circuit, the water heater 141 heats the coolant in the circuit, and the heated coolant flows into the warm air core 142, which generates hot air and is sent into the passenger compartment through the air duct. The coolant flowing out of the warm air core 142 cools down, flows into the six-way valve 21 from the fourth interface pipe D, and flows back into the heating circuit 14 through the sixth interface pipe F. In this way, the first passenger compartment heating circuit allows the heated coolant to pass through the warm air core 142 to transfer heat to the air in the passenger compartment, thereby achieving the purpose of heating the passenger compartment.

[0046] In other embodiments, the controller 11 is used to start the heater core 142 to put the heating circuit 14 in a warm air state and send a second passenger compartment heating command to the six-way valve 21 when a passenger compartment heating request is received and the battery temperature exceeds a first preset temperature.

[0047] The six-way valve 21 is used to control the driving mechanism to drive the valve core to rotate according to the second passenger compartment heating instruction, connect the third interface pipe C and the sixth interface pipe F, and connect the second interface pipe B and the fourth interface pipe D, so that the battery circuit is connected with the heating circuit, forming a second passenger compartment heating circuit corresponding to the second passenger compartment heating mode, so as to utilize the residual heat of the battery to heat the passenger compartment.

[0048] Specifically, when the controller 11 determines that the battery temperature exceeds the first preset temperature, that is, the battery 131 can provide heat to the passenger compartment, the controller 11 will start the heater core 142 and send a second passenger compartment heating instruction to the six-way valve 21 .

[0049] In addition, the controller 11 also starts the first water pump 23a and the second water pump 23b. After receiving the second passenger compartment heating instruction sent by the controller 11, the six-way valve 21 controls the valve core position by rotating the driving mechanism, so that the third interface pipe C is connected to the sixth interface pipe F, and the second interface pipe B is connected to the fourth interface pipe D, so that the output pipe port of the heating circuit 14 is connected to the input pipe port of the battery circuit 13, and the input pipe port of the heating circuit 14 is connected to the output pipe port of the battery circuit 13, forming a second passenger compartment heating circuit corresponding to the second passenger compartment heating mode.

[0050] In the second passenger compartment heating circuit, the coolant flows through the battery 131 and is heated by the excess heat of the battery. The heated coolant passes through the first water tank 22a and is pressurized by the first water pump 23a and flows from the third interface pipe C to the six-way valve 21, flows through the second water tank 22b through the sixth interface pipe F, and is pressurized by the second water pump 23b and flows through the water heater 141 and the warm air core 142. That is, the water heater 141 does not work, the warm air core 142 generates hot air and is sent into the passenger compartment through the air duct. The coolant flowing out of the warm air core 142 cools down and flows into the six-way valve 21 from the fourth interface pipe D, and flows to the battery 131 through the second interface pipe B. In this way, the second passenger compartment heating circuit uses the excess heat of the battery to heat the coolant in the circuit, and the heated coolant passes through the warm air core 142 to transfer the heat to the air in the passenger compartment, thereby achieving the purpose of recovering the battery heat and heating the passenger compartment.

[0051] In some other embodiments, the control instructions may include passenger compartment and battery heating instructions. The passenger compartment and battery heating instructions may be instructions for simultaneously implementing the passenger compartment heating function and the battery heating function, that is, instructions for controlling the integrated thermal management system to implement the passenger compartment and battery heating mode in the thermal management mode.

[0052] The controller 11 is used to start the heater core 142 and the water heater 141 to put the heating circuit in a heating state and send a passenger compartment and battery heating instruction to the six-way valve 21 when receiving a passenger compartment heating request and the battery temperature does not exceed a second preset temperature.

[0053] The six-way valve 21 is used to control the driving mechanism to drive the valve core to rotate according to the passenger compartment and battery heating instructions, connect the third interface pipe C and the sixth interface F, and connect the second interface pipe B and the fourth interface pipe D, so that the heating circuit is connected with the battery circuit, forming a passenger compartment and battery heating circuit corresponding to the passenger compartment and battery heating mode.

[0054] The second preset temperature involved in the embodiment of the present application can be set according to the vehicle design, battery characteristics and safety standards, and is used to measure whether the battery is in a low temperature state. Optionally, the second preset temperature can be 15 degrees.

[0055] In one embodiment of the present application, after obtaining a request for passenger compartment heating, the controller 11 will continue to determine whether the battery temperature does not exceed the second preset temperature after determining that the battery temperature is lower than the first preset temperature. When the battery temperature does not exceed the second preset temperature, that is, the battery is in a low temperature state, the controller will start the heater core 142 and the water heater 141, and will send a passenger compartment and battery heating instruction to the six-way valve 21.

[0056] In addition, the controller 11 also starts the first water pump 23a and the second water pump 23b. After receiving the passenger compartment and battery heating instruction sent by the controller 11, the six-way valve 21 controls the valve core position by rotating the driving mechanism, so that the third interface pipe C is connected to the sixth interface pipe F, and the second interface pipe B is connected to the fourth interface pipe D, so that the output pipe port of the heating circuit 14 is connected to the input pipe port of the battery circuit 13, and the input pipe port of the heating circuit 14 is connected to the output pipe port of the battery circuit 13, forming a passenger compartment and battery heating circuit corresponding to the passenger compartment and battery heating instruction mode.

[0057] In the passenger compartment and battery heating circuit, the coolant flows through the second water tank 22b and is pressurized by the second water pump 23b to flow to the water heater 141, that is, the water heater 141 heats the coolant, and the heated coolant flows to the warm air core, and the warm air core 142 generates hot air and is sent into the passenger compartment through the air duct. The coolant flowing out of the warm air core 142 is cooled down, and the temperature of the cooled coolant is higher than the battery temperature. The cooled coolant flows into the six-way valve 21 from the fourth interface pipe D and flows to the battery 131 through the second interface pipe B. The battery 131 is heated up, and the coolant flowing out of the battery 131 is cooled down again. The cooled coolant passes through the first water tank 22a and is pressurized by the first water pump 23a to flow into the six-way valve 21 from the third interface pipe C, and flows into the second water tank 22b through the sixth interface pipe F. In this way, the coolant circulates in the passenger compartment and the battery heating circuit, so that the coolant in the circuit is heated by the water heater 141. At the same time, the heated coolant passes through the heater core 142 and the battery 131 to transfer heat to the air in the passenger compartment and the battery 131, thereby achieving the purpose of heating the passenger compartment and the battery together.

[0058] In some embodiments, the control instruction includes a battery non-cooling instruction. The battery non-cooling instruction may be an instruction to control the integrated thermal management system to implement a battery non-cooling mode in a thermal management mode when the battery temperature is within a normal temperature range and no additional cooling is required.

[0059] The controller 11 is used to send a battery non-cooling instruction to the six-way valve 21 when the battery temperature is within a preset temperature range.

[0060] The six-way valve 21 is used to control the driving mechanism to drive the valve core to rotate according to the battery non-cooling instruction, connecting the second interface pipe B and the third interface pipe C to connect the battery circuit to form a battery non-cooling circuit corresponding to the battery non-cooling mode.

[0061] The preset temperature range involved in the embodiment of the present application can be set according to the vehicle design, battery characteristics and safety standards, and is used to measure whether the battery is in a normal temperature range. Optionally, the preset temperature range can be 20 degrees to 30 degrees.

[0062] In one embodiment of the present application, the controller 11 determines whether the battery temperature is within a preset temperature range. When the battery temperature is within the preset range, the controller 11 sends a battery non-cooling instruction to the six-way valve 21 .

[0063] In addition, the controller 11 will also start the second water pump 23a. After receiving the battery non-cooling instruction sent by the controller 11, the six-way valve 21 controls the valve core position by rotating the driving mechanism, so that the second interface pipe B is connected with the third interface pipe C, so that the input pipe port and the output pipe port of the battery circuit 13 are connected, forming a battery non-cooling circuit corresponding to the battery non-cooling mode.

[0064] In the battery non-cooling loop, the first water tank 22a replenishes coolant to the battery loop 13, and the first water pump 23a drives the coolant to flow in the battery loop. The coolant flows from the third interface pipe C into the six-way valve 21, and flows from the second interface pipe B to the battery 131. The coolant flowing through the battery 131 takes away the heat of the battery 131 and flows to the first water tank 22a. In this way, the battery non-cooling loop allows the heat generated by the battery during operation to be dissipated to the environment through natural heat dissipation without the intervention of additional cooling devices.

[0065] In some embodiments, the control instruction includes a battery heating instruction. The battery heating instruction may be an instruction for implementing a battery heating function, that is, an instruction for controlling the integrated thermal management system to implement a battery heating mode in a thermal management mode.

[0066] The controller 11 is used to start the water heater 141 when the battery temperature is lower than the second preset temperature, so as to put the heating circuit 14 into a heating state, and send a battery heating instruction to the six-way valve 21 .

[0067] The six-way valve 21 is used to control the driving mechanism to drive the valve core to rotate according to the battery heating instruction, connect the third interface pipe C and the sixth interface pipe F, and connect the second interface pipe B and the fourth interface pipe D, so that the battery circuit 13 is connected with the heating circuit 14, forming a battery heating circuit corresponding to the battery heating mode.

[0068] In one embodiment of the present application, when the controller 11 determines that the battery temperature is lower than the second preset temperature, that is, the battery 131 is in a state of too low temperature, in order to ensure that the battery operates at an appropriate temperature, the controller 11 will start the water heater 141 and send a battery heating instruction to the six-way valve 21.

[0069] In addition, the controller 11 also starts the first water pump 23a and the second water pump 23b. After receiving the battery heating instruction sent by the controller 11, the six-way valve 21 controls the valve core position by rotating the driving mechanism, so that the third interface pipe C is connected to the sixth interface pipe F, and the second interface pipe B is connected to the fourth interface pipe D, so that the output pipe port of the heating circuit 14 is connected to the input pipe port of the battery circuit 13, and the input pipe port of the heating circuit 14 is connected to the output pipe port of the battery circuit 13, forming a battery heating circuit corresponding to the battery heating mode.

[0070] It should be noted that the difference between the passenger compartment and battery heating circuit and the battery heating circuit lies in whether the controller 11 starts the heater core 142 .

[0071] In the battery heating circuit, the coolant flows through the second water tank 22b and is pressurized by the second water pump 23b to flow to the water heater 141, and the water heater 141 heats the coolant. The heated coolant flows through the warm air core 142. The warm air core 142 does not work, and the temperature of the coolant remains unchanged. The coolant flowing out of the warm air core 142 flows into the six-way valve 21 from the fourth interface pipe D through the water pipe, and flows to the battery 131 through the second interface pipe B. The battery 131 heats up, and the coolant flowing out of the battery 131 cools down. The cooled coolant passes through the first water tank 22a, and is pressurized by the first water pump 23a to flow into the six-way valve 21 from the third interface pipe C, and flows back to the second water tank 22b through the sixth interface pipe F. In this way, the coolant in the battery heating circuit is heated by the water heater, providing the required heat for the battery and raising the temperature of the battery, so that when the battery temperature is too low, the battery can be heated to ensure that the battery can work under safe temperature conditions.

[0072] like Figure 4 As shown, the air conditioning circuit 16 includes a first expansion valve 161 , a second expansion valve 162 , an evaporator 163 , a condenser 164 , a compressor 165 and a gas-liquid separator 167 .

[0073] Among them, the first expansion valve 161 and the second expansion valve 162 can be used to control the flow rate and pressure of the refrigerant. The evaporator 163 is used to evaporate the liquid refrigerant to form refrigerant vapor, so as to absorb the heat of the surrounding air and reduce the air temperature. The compressor 165 is used to compress the refrigerant vapor, increase the pressure and temperature of the refrigerant vapor, and provide circulation power for the refrigeration system. The condenser 164 is used to convert high-temperature and high-pressure refrigerant vapor into low-temperature and high-pressure liquid refrigerant. The gas-liquid separator 167 is used to store refrigerant and replenish refrigerant to the circuit. The gas-liquid separator 167 also has the function of vapor-liquid separation, and can transport the refrigerant vapor to the compressor 165 to ensure the stable operation of the circuit.

[0074] like Figure 4As shown, the input pipe port of the gas-liquid separator 167 is connected to the fourth pipe port J of the heat exchanger 151 and the output pipe port of the evaporator 163 respectively. The output pipe port of the gas-liquid separator 167 is connected to the input pipe port of the compressor 165. The output pipe port of the compressor 165 is connected to the input pipe port of the condenser 164. The output pipe port of the condenser 164 is connected to the input pipe port of the first expansion valve 161 and the input pipe port of the second expansion valve 162 respectively. The output pipe port of the first expansion valve 161 is connected to the input pipe port of the evaporator 163, and the output pipe port of the second expansion valve 162 is connected to the third pipe port I of the heat exchanger 151.

[0075] In some embodiments, the battery temperature is relatively high and natural heat dissipation cannot meet the battery heat dissipation requirements, so the battery temperature needs to be lowered through the cooling function of the air-conditioning circuit.

[0076] The control instruction may include a battery cooling instruction. The battery cooling instruction may be an instruction for simultaneously realizing the function of lowering the battery temperature, that is, an instruction for controlling the integrated thermal management system to realize a battery cooling mode in a thermal management mode.

[0077] In one embodiment, the controller 11 is used to start the compressor 165 and the condenser 164, open the second expansion valve 162 to put the air conditioning circuit in a cooling state, and send a battery cooling instruction to the six-way valve 21 when the battery temperature is higher than a third preset temperature.

[0078] The six-way valve 21 is used to control the driving mechanism to drive the valve core to rotate according to the battery cooling instruction, connect the first interface pipe A and the second interface pipe B, and connect the third interface pipe C and the fifth interface pipe E, so that the battery circuit 13 is connected with the heat exchange circuit 15, and the heat exchange circuit 15 and the air-conditioning circuit 16 perform heat exchange, forming a battery cooling circuit corresponding to the battery cooling mode.

[0079] The third preset temperature involved in the embodiment of the present application is higher than the first preset temperature. When the battery temperature is higher than the third preset temperature, it indicates that the battery is in a high temperature state and requires other equipment to assist in cooling. Optionally, the third preset temperature is 50 degrees.

[0080] Specifically, when the controller 11 determines that the battery temperature is higher than the third preset temperature, the controller 11 starts the compressor 165 and the condenser 164 , opens the second expansion valve 162 to put the air conditioning circuit 16 in a cooling state, and sends a battery cooling instruction to the six-way valve 21 .

[0081] In addition, the controller 11 will also start the first water pump 23a. After receiving the battery cooling instruction sent by the controller 11, the six-way valve 21 controls the valve core position by rotating the driving mechanism, so that the first interface pipe A is connected to the second interface pipe B, and the third interface pipe C is connected to the fifth interface pipe E, so that the output pipe port of the battery circuit 13 is connected to the input pipe port of the heat exchange circuit 15, and the input pipe port of the battery circuit 13 is connected to the output pipe port of the heat exchange circuit 15, forming a battery cooling circuit corresponding to the battery cooling mode.

[0082] In the battery cooling circuit, the first water tank 22a replenishes the coolant to the battery circuit 13, and the first water pump 23a drives the coolant to flow in the battery circuit. The coolant flows from the third interface pipe C into the six-way valve 21, and flows from the fifth interface pipe E into the heat exchange circuit 15. At the same time, the gas-liquid separator 167 is started to deliver refrigerant vapor to the compressor 165, the compressor 165 and the condenser 164 are started to convert the refrigerant vapor into a low-temperature liquid refrigerant, and the second expansion valve 162 is opened, so that the entire air-conditioning circuit 16 enters the refrigeration state. At the same time, the low-temperature liquid refrigerant in the air-conditioning circuit 16 flows into the heat exchanger 151 through the second expansion valve 162. In the heat exchanger 151, the low-temperature refrigerant exchanges heat with the coolant to reduce the temperature of the coolant and increase the temperature of the refrigerant. The cooled coolant flows into the first interface pipe A through a section of water pipe, and flows from the second interface pipe B to the battery 131. The coolant flowing through the battery 131 takes away the heat of the battery 131 and flows back to the first water tank 22a. And the heated refrigerant flows back from the heat exchanger 151 to the gas-liquid separator 167. In this way, the heat generated by the battery is transferred to the refrigerant in the air conditioning circuit 16 through the heat exchange circuit 15, and is carried away by the refrigerant and discharged to the external environment, thereby cooling the battery.

[0083] like Figure 4 As shown, the integrated thermal management system also includes a fan FAN and a blower BLOW. The radiator 175, the condenser 164 and the fan FAN are integrated together. The heater core 142, the evaporator 163 and the blower BLOW are integrated together. In this way, the system volume can be reduced.

[0084] In one embodiment of the present application, the fan FAN is used for the exchange of the radiator and the condenser with the outside air. The blower BLOW is used to blow the cold air generated by the evaporator into the passenger compartment, and can also be used to blow the hot air generated by the heater core 142 into the passenger compartment.

[0085] After receiving the passenger compartment heating request, the integrated thermal management system will cool the passenger compartment through the air conditioning circuit 16. In some embodiments, the controller 11 is used to start the compressor 165, the condenser 164, and the evaporator 163, and open the first expansion valve 161 to put the air conditioning circuit 16 in a cooling state when receiving the passenger compartment cooling request. In addition, the controller 11 is also used to start the blower BLOW.

[0086] Specifically, when receiving a request to cool the passenger compartment, the controller 11 controls the refrigerant to pass through the gas-liquid separator 16, the compressor 165, the condenser 164, the first expansion valve 161 and the evaporator 163 in sequence, so that the air-conditioning circuit 16 is in a cooling state, and the cold air produced by the air-conditioning circuit 16 is transferred to the passenger compartment through the blower, forming a passenger compartment cooling circuit corresponding to the passenger compartment cooling mode.

[0087] In the passenger compartment cooling circuit, the gas-liquid separator 167 is started to deliver refrigerant vapor to the compressor 165, the compressor 165 and the condenser 164 are started to convert the refrigerant vapor into a low-temperature liquid refrigerant, and the first expansion valve 161 is opened, the liquid refrigerant flows into the evaporator 163, the evaporator 163 converts the liquid refrigerant into refrigerant vapor by absorbing heat from the air, the refrigerant vapor flows back to the gas-liquid separator 167, and the cold air generated by the evaporator 163 is delivered to the passenger compartment by the blower BLOW.

[0088] In some embodiments, the control instructions include passenger compartment and battery cooling instructions. The passenger compartment and battery cooling instructions may be instructions for simultaneously implementing the passenger compartment cooling function and the battery cooling function, that is, instructions for controlling the integrated thermal management system to implement the passenger compartment and battery cooling mode in the thermal management mode.

[0089] The controller 11 is used to start the gas-liquid separator 167, the compressor 165 and the condenser 164, open the first expansion valve 161 and the second expansion valve 162 to put the air-conditioning circuit in a cooling state, and send a battery cooling instruction to the six-way valve 21 when a request for cooling the passenger compartment is received and the battery temperature exceeds a third preset temperature.

[0090] The six-way valve 21 is used to control the driving mechanism to drive the valve core to rotate according to the battery cooling instruction, connect the first interface pipe A and the second interface pipe B, and connect the third interface pipe C and the fifth interface pipe E, so that the battery circuit 13 is connected with the heat exchange circuit 15, and the heat exchange circuit 15 and the air-conditioning circuit 16 perform heat exchange, forming a passenger compartment and battery cooling circuit corresponding to the passenger compartment and battery cooling mode.

[0091] It should be noted that the passenger compartment cooling principle in the passenger compartment and battery cooling circuit is the same as that in the passenger compartment cooling circuit in the aforementioned embodiment, and the battery cooling principle in the passenger compartment and battery cooling circuit is the same as that in the aforementioned battery cooling circuit. For the sake of brevity, they will not be repeated here.

[0092] It should be noted that in the passenger compartment and battery cooling circuit, the liquid refrigerant flowing out of the condenser 164 flows to the first expansion valve 161 and the second expansion valve 162 respectively, so as to realize the passenger compartment cooling and battery cooling functions. The inflow of the refrigerant into the evaporator 163 and the heat exchanger 151 can be determined respectively by adjusting the valves of the first expansion valve 161 and the second expansion valve 162, thereby determining the degree of cooling of the passenger compartment and the degree of cooling of the battery respectively.

[0093] like Figure 4 As shown, the motor circuit 17 may include a three-way valve 171 , a motor 172 , a third water pump 173 , a third water tank 174 and a radiator 175 .

[0094] The three-way valve 171 includes a seventh interface pipe K, an eighth interface pipe L, and a ninth interface pipe M. The seventh interface pipe K is connected to one pipe port of the motor 172, the other pipe port of the motor 172 is connected to the output pipe port of the third water pump 173, the input pipe port of the third water pump 173 is connected to the output pipe port of the third water tank 174, the input pipe port of the third water tank 174 is connected to the eighth interface pipe L, the eighth interface pipe L is also connected to one pipe port of the radiator 175, and the other pipe port of the radiator 175 is connected to the ninth interface pipe M.

[0095] It should be noted that all components in the motor circuit 17 are connected via water pipes.

[0096] The three-way valve 171 may also include a driving mechanism and a valve core. The working principle of the three-way valve 171 is not specifically limited in this application.

[0097] The three-way valve 171 is used to connect two interface pipes according to the control instruction to form a thermal management loop corresponding to the thermal management mode. The thermal management mode includes but is not limited to the motor heat dissipation mode and the motor non-heat dissipation mode, and the thermal management loop may include but is not limited to the motor heat dissipation loop and the motor non-heat dissipation loop.

[0098] In some embodiments, the control instruction includes: a motor heat dissipation instruction. The motor heat dissipation instruction may be an instruction for implementing a motor heat dissipation function, that is, an instruction for controlling the integrated thermal management system to implement a motor heat dissipation mode in a thermal management mode.

[0099] The controller 11 is used to start the radiator 175 and send a motor cooling instruction to the three-way valve 171 when the motor temperature exceeds a fourth preset temperature.

[0100] The three-way valve 171 is used to connect the seventh interface pipe K and the ninth interface pipe M according to the motor heat dissipation instruction to form a motor heat dissipation loop corresponding to the motor heat dissipation mode.

[0101] The fourth preset temperature involved in the embodiment of the present application can be set according to the vehicle design, motor characteristics and safety standards, and is a safety critical value of the motor temperature. Optionally, the fourth preset temperature can be 65 degrees.

[0102] In one embodiment of the present application, the controller 11 determines whether the motor temperature exceeds a fourth preset temperature. When the motor temperature exceeds the fourth preset temperature range, the controller 11 starts the radiator 175 and sends a motor cooling instruction to the three-way valve 171 .

[0103] In addition, the controller 11 also starts the third water pump 173. After receiving the motor cooling instruction sent by the controller 11, the three-way valve 21 controls the valve core position by rotating the driving mechanism, and the seventh interface pipe K and the ninth interface pipe M are connected, so that one pipe port of the motor 172 is connected to one pipe port of the radiator 175, and the other pipe port of the radiator 175 is connected to the input pipe port of the third water tank 174, forming a motor cooling loop corresponding to the motor cooling mode.

[0104] In the motor heat dissipation circuit, the third water tank 174 replenishes the coolant into the circuit, and the coolant is pressurized by the third water pump 173 and flows to the motor 172. The coolant flowing through the motor 172 is heated. The heated coolant flows from the seventh interface pipe K into the three-way valve 171, and flows from the ninth interface pipe M into the radiator 175. After the heat is dissipated by the radiator 175, the coolant temperature decreases, and flows back to the third water tank 174 through a section of water pipe. In this way, the coolant circulates in the motor heat dissipation circuit, thereby taking away the heat of the motor with the coolant, and cooling the coolant with the radiator, thereby achieving the purpose of heat dissipation of the motor.

[0105] In some embodiments, the control instruction may include a motor no heat dissipation instruction. The motor no heat dissipation instruction may be an instruction to control the integrated thermal management system to implement a motor no heat dissipation mode in the thermal management mode.

[0106] The controller 11 is used to send a motor non-heat dissipation instruction to the three-way valve 171 when the motor temperature does not exceed a fourth preset temperature.

[0107] The three-way valve 171 is used to connect the seventh interface pipe K and the eighth interface pipe L according to the motor no heat dissipation instruction to form a motor no heat dissipation circuit corresponding to the motor no heat dissipation mode.

[0108] In one embodiment of the present application, when the controller 11 determines that the motor temperature exceeds the fourth preset temperature, it sends a motor non-heat dissipation instruction to the three-way valve 171.

[0109] In addition, the controller 11 also starts the third water pump 173. After receiving the motor heat dissipation instruction sent by the controller 11, the three-way valve 21 controls the valve core position by rotating the driving mechanism, and the seventh interface pipe K and the eighth interface pipe L are connected, so that one pipe opening of the motor 172 is connected to one pipe opening of the long water pipe, and the other pipe opening of the long water pipe is connected to the input pipe opening of the third water tank 174, forming a motor non-heat dissipation circuit corresponding to the motor non-heat dissipation mode.

[0110] In the motor non-heat dissipation circuit, the third water tank 174 replenishes the cooling liquid into the circuit, and the cooling liquid is pressurized by the third water pump 173 and flows to the motor 172. The cooling liquid flows out of the motor 172, flows into the three-way valve 171 from the seventh interface pipe K, and flows into the long water pipe from the eighth interface pipe L, and flows back to the third water tank 174 through the long water pipe. In this way, the cooling liquid circulates in the motor non-heat dissipation circuit, so that the circulating cooling liquid takes away the heat generated by the motor 172 during operation, thereby maintaining the normal operating temperature of the motor.

[0111] In some embodiments, the integrated thermal management system may further include a plurality of sensors. The plurality of sensors include a first temperature sensor T1, a second temperature sensor T2, and a third temperature sensor T3. Figure 4 As shown, the first temperature sensor T1 and the second temperature sensor T2 are arranged in the motor circuit 17 , and the third temperature sensor T3 is arranged in the battery circuit 13 .

[0112] In one embodiment of the present application, the first temperature sensor T1 and the second temperature sensor T2 measure the temperature of the water inlet and the water outlet of the motor respectively. The third temperature sensor T3 measures the temperature of the water inlet of the battery 131 .

[0113] The multiple sensors may also include a pressure sensor P and a pressure temperature sensor PT. Figure 4 As shown, a pressure sensor P and a pressure temperature sensor PT may be provided in the air conditioning circuit 16. The pressure sensor P is used to measure the pressure of the refrigerant at the compressor outlet, and the pressure temperature sensor PT is used to measure the pressure and temperature of the refrigerant at the compressor inlet.

[0114] In some embodiments, the thermal management mode is determined by the integrated thermal management system based on whether there is a passenger compartment heating request, the motor temperature, and the battery temperature.

[0115] In some embodiments, since the motor circuit 17 is not connected to other circuits in the integrated thermal management system, the integrated thermal management system can implement at least one thermal management system during actual operation, such as simultaneously implementing a motor cooling mode and a battery cooling mode.
