[0002] With the popularity of electric vehicles and the continuous advancement of technology, relevant designers usually increase the battery power to alleviate the problem of electric vehicle endurance, and the large-capacity battery can achieve fast charging. However, due to the heating characteristics of the battery cell, the large-capacity battery generates a lot of heat. If you want to complete the charging at the allowable temperature of the battery cell, you need to dissipate the heat in a shorter time. This is one of the problems that need to be solved for large-capacity batteries to achieve fast charging. In addition, when electric vehicles use drive motors as driving power, when the motor is required to be in a higher operating power or peak power condition (such as continuous climbing), the motor generates a lot of heat in a short time.

[0043] In this embodiment, if Figure 1As shown, the air conditioning module is provided with a refrigeration circuit and a heating circuit connected in parallel with each other. The refrigeration circuit includes a first refrigeration circuit, which includes a liquid storage tank 10, a compressor 11, a first solenoid valve 12, a first condenser 13, a first non-return valve 14, a first electronic expansion valve 15, and a refrigerator 16 (i.e., Chiller) connected end to end in sequence.

That is, the liquid storage tank 10, the compressor 11, the first solenoid valve 12, the first condenser 13, the second solenoid valve 20, the thermal expansion valve 21, the evaporator 22, and the second non-return valve 23 are connected end to end in sequence to form a second refrigeration circuit.

[0044] Similar to the above refrigeration circuit, if Figure 1 As shown, the heating circuit includes a third solenoid valve 30 and a second condenser 31 connected in sequence, the inlet end of the third solenoid valve 30 is connected between the compressor 11 and the first solenoid valve 12, and the second condenser 31 is connected between the first check valve 14 and the first electronic expansion valve 15, that is, the liquid storage tank 10, the compressor 11, the third solenoid valve 30, the second condenser 31, the first electronic expansion valve 15 and the refrigerator 16 are connected end to end in sequence to form a first heating circuit. In addition, the heating circuit also includes a second electronic expansion valve 32 and a heat exchanger 33 connected in sequence, the inlet end of the second electronic expansion valve 32 is connected between the second condenser 31 and the first electronic expansion valve 15, and the outlet end of the heat exchanger 33 is connected between the liquid storage tank 10 and the refrigerator 16, that is, the liquid storage tank 10, the compressor 11, the third solenoid valve 30, the second condenser 31, the second electronic expansion valve 32 and the heat exchanger 33 are connected end to end in sequence to form a second heating circuit.

[0045] It should be noted that in this embodiment, a condensing fan is provided outside the first condenser 13, thereby effectively improving the condensing effect. Blowers are provided outside the evaporator 22 and the second condenser 31, thereby respectively improving the cooling and heating effects on the passenger compartment.

[0046] In this embodiment, if Figure 1 As shown, the battery 43 cooling module includes a first three-way valve 40, a first expansion water tank 41, a first water pump 42 and a battery 43; the refrigerator 16, the first three-way valve 40, the first expansion water tank 41, the first water pump 42 and the battery 43 are connected end to end in sequence to form a loop of the battery 43 cooling module. Specifically, the outlet end of the refrigerator 16 is connected to the A port of the first three-way valve 40, and the inlet end of the first water pump 42 is connected to the B port of the first three-way valve 40.

[0047] In this embodiment, if Figure 1 As shown, the motor electronic control cooling module includes a motor electronic control component 50, a second three-way valve 51, a third three-way valve 52, an ATS component 53, a third one-way valve 54, a second expansion water tank 55 and a second water pump 56 connected in sequence to form a loop of the motor electronic control cooling module; the heat exchanger 33 is connected in parallel to both ends of the ATS component 53. That is, the inlet end of the heat exchanger 33 is connected to the S port of the third three-way valve 52, the inlet end of the ATS component 53 is connected to the Y port of the third three-way valve 52, the M port of the second three-way valve 51 is connected to the R port of the third three-way valve 52, and the outlet end of the motor electronic control component 50 is connected to the P port of the second three-way valve 51.

[0048] In this way, the battery 43 cooling module can be connected to the above-mentioned air-conditioning module through the refrigerator 16, and the motor electronic control module can be connected to the above-mentioned air-conditioning module through the heat exchanger 33.

[0049] In this embodiment, if Figure 1 As shown, the water cooling module includes a water cooling unit 60 and a valve. By controlling the opening and closing of the valve, the water cooling unit 60 can be controlled to be connected to the battery 43 cooling module, or connected to the motor electronic control cooling module, or in an open circuit state. In this way, the water cooling unit 60 can flexibly dissipate heat for the battery 43 or the motor electronic control component 50 according to the actual working conditions of the car, or be in an open circuit state when the above modules can meet the heat dissipation requirements. Specifically, the water cooling unit 60 is connected in parallel to the two ends of the battery 43 through the first on-off valve 61, and the first on-off valve 61 is located between the outlet end of the battery 43 and the inlet end of the water cooling unit 60; in addition, the water cooling unit 60 is connected to the motor electronic control component 50 through the second three-way valve 51, that is, the N port of the second three-way valve 51 is connected to the inlet end of the water cooling unit 60, and the outlet end of the water cooling unit 60 is connected to the inlet end of the second water pump 56.

[0050] like Figure 1 As shown, the warm air module in this embodiment includes a warm air core 70, a water heater 71, a second on-off valve 72, a third expansion water tank 73 and a third water pump 74 which are connected end to end in sequence to form a circuit of the warm air module.

[0051] In this way, by controlling the on and off of each valve, the system can be controlled to be in different states to adapt to different working conditions of the car. The following will explain the state of the system when the car is in various working conditions.

[0052] like Figure 2 As shown, when the car is driving normally in summer, the motor and electronic control dissipate heat through the ATS cooling module, and the air conditioning system cools the passenger compartment and the battery 43.

[0053] Specifically, the first solenoid valve 12 and the second solenoid valve 20 are opened, the third solenoid valve 30 and the second electronic expansion valve 32 are closed, the first refrigeration circuit and the second refrigeration circuit are working, and the distribution of cooling capacity can be achieved by adjusting the first electronic expansion valve 15 and the thermal expansion valve 21. The refrigerant dissipates heat to the outside air through the first condenser 13 and becomes a medium-temperature and high-pressure state; then, a part of the refrigerant in the medium-temperature and high-pressure state is converted into a low-temperature and low-pressure state through the thermal expansion valve 21, and then absorbs heat from the passenger compartment through the evaporator 22; the other part of the refrigerant in the medium-temperature and high-pressure state is converted into a low-temperature and low-pressure state through the first electronic expansion valve 15, and then absorbs the heat of the coolant in the battery 43 cooling module circuit in the refrigerator 16. The above two parts of refrigerant are compressed by the compressor 11 to become high-temperature and high-pressure refrigerants and flow back into the first condenser 13.

[0054] In addition, the A port and the B port of the first three-way valve 40 are connected, the first on-off valve 61 and the second on-off valve 72 are in a closed state, and the coolant flowing out of the battery 43 enters the refrigerator 16 for cooling, and then flows through the first three-way valve 40 and the first water pump 42 and enters the battery 43 to achieve cooling of the battery 43. In this loop, the speed of the first water pump 42 can be adjusted, thereby adjusting the flow rate of the coolant in the loop to ensure that the battery 43 is in a normal operating temperature range.

[0055] In addition, the P port and the M port of the second three-way valve 51 are connected, and the R port and the T port of the third three-way valve 52 are connected. The coolant flowing out of the motor electronic control component 50 flows through the second three-way valve 51 and the third three-way valve 52, and then enters the ATS component 53 for heat dissipation. The cooled coolant enters the second water pump 56 through the third one-way valve 54, and then enters the motor electronic control component 50. In this loop, the speed of the second water pump 56 and the electronic fan in the ATS component 53 can be adjusted to ensure that the motor electronic control component 50 is in the normal working temperature range.

[0056] like Figure 3 As shown, when the car is driving normally in winter, the air conditioning system heats the passenger compartment by absorbing the heat of the motor electronically controlled cooling module, and the battery 43 performs self-circulation.

[0057] Specifically, the first solenoid valve 12 and the second solenoid valve 20 are in a closed state, the third solenoid valve 30 is in an open state, the first electronic expansion valve 15 is closed and the second electronic expansion valve 32 is opened, and the low-temperature and low-pressure refrigerant in the heat exchanger 33 absorbs heat from the coolant of the motor electronic control cooling module, and then enters the compressor 11 to become a high-temperature and high-pressure refrigerant, and then flows into the second condenser 31 to be able to dissipate heat to the passenger compartment, and then the refrigerant becomes a medium-temperature and high-pressure state, and then passes through the second electronic expansion valve 32 to become a low-temperature and low-pressure state.

[0058] In addition, the A port and the B port of the first three-way valve 40 are connected, the first on-off valve 61 and the second on-off valve 72 are both in a closed state, and the coolant of the battery 43 is self-circulated to achieve cooling of the battery 43. In addition, the P port and the M port of the second three-way valve 51 are connected, and the three structures of the third three-way valve 52 are all connected. The coolant of the motor electronic control component 50 flows through the third three-way valve 52 and is divided into two parts. One part enters the heat exchanger 33 to provide heat for the circulation of the above-mentioned refrigerant, and the other part passes through the ATS component 53 to achieve heat dissipation of the motor electronic control component 50.

[0059] like Figure 4 As shown, when the car is parked in winter, the heating module can be used to heat the passenger compartment. Specifically, the A port and the B port of the first three-way valve 40 are connected, the second on-off valve 72 is in an open state, the water heater 71 is running and heats the coolant, and the heated coolant flows through the second on-off valve 72 and the third water pump 74, and then enters the heating core 70 to dissipate heat to the passenger compartment.

[0060] like Figure 5 As shown, when the car needs to be defrosted before driving in winter, the air conditioning module achieves defrosting by absorbing the heat generated by the water heater 71. Specifically, the first solenoid valve 12 and the second solenoid valve 20 are in a closed state, the third solenoid valve 30 is in an open state, the second electronic expansion valve 32 is closed and the first electronic expansion valve 15 is opened. In the refrigerator 16, the low-temperature and low-pressure refrigerant takes heat from the coolant on the other side of the refrigerator 16, and then enters the compressor 11 to become a high-temperature and high-pressure state, and dissipates heat to the passenger compartment through the second condenser 31, and then becomes a medium-temperature and high-pressure state, and then becomes a low-temperature and low-pressure state after passing through the first electronic expansion valve 15. In the above process, the technical effect of defrosting the passenger compartment glass can be achieved. In addition, the A port and the C port of the first three-way valve 40 are connected and the first on-off valve 61 is closed, and the coolant enters the refrigerator 16 after being heated by the water heater 71, and then enters the third water pump 74 and the warm air core 70 through the first three-way valve 40.

[0061] like Figure 6 As shown, when the motor is running at peak power, the water cooling unit 60 dissipates heat from the motor electronic control component 50, and the air conditioning module cools the passenger compartment and the battery 43. Specifically, the air conditioning module cools the passenger compartment and the battery 43. Figure 2 In addition, the first on-off valve 61 is closed and the P port and the N port of the second three-way valve 51 are connected, and the coolant in the motor electronic control cooling module circuit enters the water cooling unit 60 for cooling. The water cooling unit 60 can quickly take away the heat of the motor by using the lower water temperature, so that the normal operation of the motor at peak power can be effectively guaranteed (without issuing a high temperature alarm).

[0062] like Figure 7As shown, when the car is parked and the battery 43 is fast charged, the battery 43 dissipates heat through the water cooling unit 60 and the above-mentioned first refrigeration circuit. Specifically, the first solenoid valve 12 is opened, the second solenoid valve 20 and the third solenoid valve 30 are closed, the second electronic expansion valve 32 is closed, and the first electronic expansion valve 15 is opened. The A port and the B port of the first three-way valve 40 are connected, and the first on-off valve 61 is opened. The coolant flowing out of the battery 43 is divided into two paths, one part flows through the first on-off valve 61 and enters the water cooling unit 60 for cooling, and the other part enters the refrigerator 16 for cooling, and then flows through the first three-way valve 40 and the first water pump 42. The above two parts of coolant are collected and then flow back into the battery 43. In this way, the heat dissipation efficiency of the battery 43 can be effectively improved, thereby ensuring the heat dissipation requirements of the large-capacity battery 43 during fast charging.

[0063] In addition, it should be noted that the battery 43 in this embodiment is provided with a heating film, and when the vehicle is cold-started or the battery 43 needs to be heated, the battery 43 can be heated by the heating film.

[0064] According to the thermal management system of the present invention, the passenger compartment can be cooled or heated by the air conditioning module; the battery 43 cooling module is connected to the air conditioning module through the refrigerator 16, so that the air conditioning module can cool the battery 43 in addition to cooling the passenger compartment; the motor electronic control cooling module is connected to the air conditioning module through the heat exchanger 33, which can cool the motor electronic control component 50, that is, the air conditioning module can absorb the heat of the motor electronic control component 50; in addition, the thermal management system is also provided with a water cooling module, which can control the water cooling unit 60 to be connected to the battery 43 cooling module or to be connected to the motor electronic control cooling module or to be in an open circuit state through the opening and closing of the valve, that is, the water cooling unit 60 can flexibly dissipate heat for the battery 43 or the motor electronic control component 50 according to the actual working conditions of the car, or be in an open circuit state when the above modules can meet the heat dissipation requirements. In this way, the thermal management system can meet the fast charging requirements of large-capacity batteries and can ensure that the motor operates at peak power.

[0065] In addition, the thermal management system is also provided with a warm air module, which can achieve the technical effect of defrosting and heating the passenger compartment.
