Compared to traditional gasoline-powered vehicles, EVs offer significant advantages such as zero emissions and low noise, but their operating principles also present unique challenges. An efficient thermal management system is essential for EVs. It not only needs to effectively dissipate heat from core components like the battery to maintain the battery within its optimal temperature range, extending its lifespan and ensuring safety, but also needs to properly cool the motor and meet the comfort requirements of the passenger compartment. During its long-term research and development process, the applicant of this application discovered that the numerous and complex pipelines increase the difficulty of controlling the thermal management system and hinder waste heat recovery and utilization.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0044] See Figure 1 and Figure 2 The thermal management system 1 includes a multi-way valve 10, a passenger compartment module 20, a motor module 30, a heat dissipation module 40, a battery module 50, and a battery cooler 60.

[0045] The multi-way valve 10 includes a valve body and a valve core. The valve body is provided with multiple valve ports arranged circumferentially along the valve core. One end of the passenger compartment module 20 is connected to the first valve port M1, and the other end of the passenger compartment module 20 is connected to the second valve port M2. One end of the motor module 30 is connected to the third valve port M3, and the other end of the motor module 30 is connected to the fourth valve port M4. One end of the heat dissipation module 40 is connected to the fourth valve port M4, and the other end of the heat dissipation module 40 is connected to the fifth valve port M5. One end of the battery module 50 is connected to the sixth valve port M6, and the other end of the battery module 50 is connected to the seventh valve port M7. One end of the battery cooler 60 is connected to the eighth valve port M8, and the other end of the battery cooler 60 is connected to the ninth valve port M9. The seventh valve port M7 and the eighth valve port M8 are the same valve port, or the seventh valve port M7 and the eighth valve port M8 are different valve ports.

[0046] Specifically, the multi-port valve 10 is provided with multiple valve ports, which are arranged around the circumference of the valve core. Different valve ports can be connected not only inside the valve core, but also outside the valve body through functional modules such as the crew compartment module 20 and the motor module 30. The first valve port M1 to the ninth valve port M9 are arranged clockwise, counterclockwise, or in an irregular order around the circumference of the valve core.

[0074] See Figure 25 The crew compartment module 20 includes a first heat exchanger 210, a heater core 220, and a heating water pump 230 connected in sequence. The first heat exchanger 210 is connected to a first valve port M1, and the heating water pump 230 is connected to a second valve port M2. The first heat exchanger 210, the heater core 220, and the heating water pump 230 are connected in sequence to form a crew compartment water circuit, and the heater core 220 is used for heating the crew compartment.

[0075] In one embodiment, the heater core 220 is disposed in the front row area of ​​the passenger compartment, and the thermal management system 1 also includes a heater disposed in the rear row area of ​​the passenger compartment. Both the heater core 220 and the heater are used for heating the passenger compartment. By distributing the heater core 220 and the heater in the front and rear rows of the passenger compartment respectively, zoned heating of the passenger compartment can be achieved, which is beneficial for the refined management of passenger compartment heat and thus reduces vehicle energy consumption.

[0076] Continue reading Figure 25The passenger compartment module 20 also includes a water heater 240. The inlet of the water heater 240 is connected to the first heat exchanger 210, and the outlet of the water heater 240 is connected to the heater core 220. In other words, the passenger compartment water circuit also includes the water heater 240. The water heater 240, the first heat exchanger 210, the heater core 220 and the heating water pump 230 are connected in sequence to form the passenger compartment water circuit. The water heater 240 has a positive temperature coefficient characteristic. The higher the temperature, the greater its resistance value. When energized, it will heat up rapidly and reach its working temperature, and start to generate heat efficiently, thereby significantly shortening the waiting time for the temperature inside the vehicle to rise in winter and improving passenger comfort.

[0077] In another embodiment, the water heater 240 is used in the motor module 30 and can serve as a reliable independent or supplementary heat source during the initial cold start of the motor or when the ambient temperature is extremely low.

[0078] Continue reading Figure 25 The crew cabin module 20 includes a gas-liquid separator 250 and a compressor 260, and the first heat exchanger 210, the battery cooler 60, the gas-liquid separator 250 and the compressor 260 are connected in sequence. The outlet of the compressor 260 is connected to the first refrigerant port 211 of the first heat exchanger 210.

[0079] Specifically, the first heat exchanger 210, battery cooler 60, gas-liquid separator 250, and compressor 260 are sequentially connected to form a first refrigerant circuit. The first heat exchanger 210 is used to exchange heat with the air. For example, in cooling mode, the first heat exchanger 210 can release heat to the air; in heating mode, the first heat exchanger 210 can absorb heat from the air. The gas-liquid separator 250 is used to separate liquid and gaseous refrigerant. Separating the liquid and gas prevents liquid from entering the compressor 260, avoiding liquid slugging, thereby ensuring the normal operation of the compressor 260 and preventing it from overloading or being damaged. After separating the liquid and gaseous refrigerant, the gas-liquid separator 250 delivers gas to the compressor 260. The compressor 260 compresses the gas and sends it into the first heat exchanger 210. The first heat exchanger 210 delivers coolant to the battery cooler 60, thereby cooling the battery in the battery module 50.

[0080] See Figure 26 The crew cabin module 20 also includes an outdoor heat exchanger 270 and a temperature sensor 280. The first port 271 of the outdoor heat exchanger 270 is connected to the first refrigerant port 211 of the first heat exchanger 210, and the second port 272 of the outdoor heat exchanger 270 is connected to the second refrigerant port 212 of the first heat exchanger 210. The temperature sensor 280 is connected to the first port 271 of the outdoor heat exchanger 270. The temperature sensor 280 detects the temperature of the first port 271 of the outdoor heat exchanger 270, thereby improving the control accuracy of the electronic valve 281 located on the side of the outdoor heat exchanger 270.

[0081] Furthermore, one end of the electronic valve 281 is connected to the second refrigerant port 212 of the first heat exchanger 210 and the second port 272 of the outdoor heat exchanger 270, respectively, and the other end of the electronic valve 281 is connected to the first refrigerant port 211 of the first heat exchanger 210 and the first port 271 of the outdoor heat exchanger 270, respectively. The temperature sensor 280 improves the control accuracy of the electronic valve 281.
