[0078] As described in the background technology, extended-range vehicles are a type of new energy vehicles that can operate in pure electric mode and extend their range through an on-board auxiliary power generation device when the battery power is insufficient.

[0079] Extended-range vehicles typically consist of a range extender assembly and a power battery system. The range extender assembly generates electricity to charge the power battery or directly drive the electric motor when the battery charge is low, thereby extending the vehicle's range. Furthermore, the range extender assembly generates a significant amount of heat during operation. Failure to dissipate heat promptly and effectively can affect not only the performance and lifespan of the range extender assembly but also the power battery system and other electronic components.

[0080] In related technologies, two independent paths are usually used to dissipate heat for the range extender assembly and the battery, which results in energy waste and increases energy consumption.

[0081] To address the above-mentioned issues, embodiments of the present application provide a thermal management system and a vehicle. The thermal management system includes a range extender assembly having a first outlet, a second outlet, a first inlet, and a second inlet, the first outlet and the first inlet being connected via a first circulation line; a first radiator disposed on the first circulation line; a PTC module connected to the range extender assembly via a second circulation line, the ends of the second circulation line being connected to the second outlet and the second inlet, respectively; a first heat exchanger disposed on the second circulation line; and a battery module connected to the first heat exchanger via a third circulation line, the third circulation line being connected to the ends of the battery module, respectively. The range extender assembly can dissipate heat through the first radiator. Simultaneously, the battery module is used to power the PTC module, causing the PTC module to generate heat. Since the battery module is connected to the first heat exchanger via the third circulation line, heat exchange can be achieved between the first heat exchanger and the PTC module, transferring heat generated by the PTC module to the battery module. The PTC module heats the battery module, thereby achieving efficient energy utilization and avoiding energy waste.

[0082] In addition, the heat generated by the range extender assembly can also be exchanged with the battery module through the first heat exchanger on the second circulation pipeline, thereby achieving heat dissipation of the range extender assembly and heating of the battery module at the same time.

[0083] The following describes in detail the technical solutions of the embodiments of the present application and how the technical solutions of the embodiments of the present application solve the above-mentioned technical problems with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0084] Please refer to Figures 1 to 3 In a first aspect, this embodiment provides a thermal management system, including a range extender assembly 101 having a first outlet port 1011, a second outlet port 1012, a first inlet port 1014, and a second inlet port 1015, wherein the first outlet port 1011 and the first inlet port 1014 are connected via a first circulation pipeline 102; a first radiator 103 is disposed on the first circulation pipeline 102; a PTC module 104 is connected to the range extender assembly 101 via a second circulation pipeline 105, wherein both ends of the second circulation pipeline 105 are respectively connected to the second outlet port 1012 and the second inlet port 1015; a first heat exchanger 106 is disposed on the second circulation pipeline 105; and a battery module 107 is connected to the first heat exchanger 106 via a third circulation pipeline 108, wherein the third circulation pipeline 108 is respectively connected to both ends of the battery module 107.

[0085] Specifically, the range extender assembly 101 generates electricity when the vehicle's battery is low, either to charge the power battery or directly drive the electric motor, thereby extending the vehicle's range. The operation of the range extender assembly 101 generates a significant amount of heat, causing the temperature inside the range extender assembly 101 to rise sharply, thus affecting its performance and lifespan. The battery module 107 powers the PTC module 104 (Positive Temperature Coefficient) thermistor. The PTC module 104 is heated by electric current. Its positive temperature coefficient increases its resistance as temperature rises, limiting current flow and achieving temperature regulation. As the vehicle's energy storage unit, the battery module 107's activity decreases in low temperatures, affecting its charging and discharging capabilities. Excessive temperature increases accelerate the rate of chemical reactions within the module, leading to capacity degradation and shortened battery life.

[0086] In summary, this embodiment provides a thermal management system, wherein the first outlet port 1011 and the first inlet port 1014 of the range extender assembly 101 are connected via a first circulation pipeline 102, and the first radiator 103 is disposed on the first circulation pipeline 102, so that the heat discharged from the first outlet port 1011 can pass through the first radiator 103. Through the heat dissipation effect of the first radiator 103, the heat is effectively dissipated into the surrounding environment, thereby achieving heat dissipation of the range extender assembly 101.

[0087] Specifically, in this embodiment, the first radiator 103 is a high-temperature radiator, which can continuously and efficiently dissipate heat, ensuring that the range extender assembly 101 maintains stable heat dissipation performance under long-term, high-load operation.

[0088] In this embodiment, a first heat exchanger 106 is provided on the second circulation pipeline 105, and the battery module 107 is connected to the first heat exchanger 106 via the third circulation pipeline 108. When the battery module 107 needs to be heated, the PTC module 104 begins to operate and generate heat, which heats the heat storage medium in the second circulation pipeline 105, causing the high-temperature heat storage medium to flow through the second circulation pipeline 105 to the first heat exchanger 106. In the first heat exchanger 106, the high-temperature heat storage medium exchanges heat with the low-temperature heat storage medium flowing in the third circulation pipeline 108, causing the low-temperature heat storage medium in the third circulation pipeline 108 to heat up and flow to the battery module 107, thereby heating the battery module 107.

[0089] In this embodiment, the range extender assembly 101 further has a second outlet port 1012 and a second inlet port 1015, and the second outlet port 1012 and the second inlet port 1015 are connected through the second circulation pipeline 105, so that a portion of the heat of the range extender assembly 101 can be discharged to the second circulation pipeline 105 through the second outlet port 1012, and flows through the PTC module 104 and the first heat exchanger 106 through the second circulation pipeline 105, thereby transferring the heat generated by the range extender assembly 101 to the battery module 107, avoiding energy waste and improving the heating efficiency of the battery module 107.

[0090] The heat storage medium may be a medium with good thermal conductivity and thermal stability. For example, the heat storage medium is a coolant.

[0091] In this embodiment, a circulation pump is provided on both the second circulation pipeline 105 and the third circulation pipeline 108 , thereby enhancing the fluidity and circulation efficiency of the refrigerant.

[0092] In an optional embodiment, the thermal management system also includes a first switching valve 109 and a first pipeline 110, the two ends of the first pipeline 110 are respectively connected to the second circulation pipeline 105, and the first switching valve 109 is arranged at the connection between the first pipeline 110 and the second circulation pipeline 105. The first switching valve 109 is configured to control the connection and closing of the first pipeline 110 and the second circulation pipeline 105, as well as the connection or closing of the second circulation pipeline 105.

[0093] Specifically, in this embodiment, both ends of the first pipeline 110 are respectively connected to the second circulation pipeline 105, and the first switch valve 109 is arranged at the connection between the first pipeline 110 and the second circulation pipeline 105 to control the connection and closing of the first pipeline 110 and the second circulation pipeline 105, as well as the connection or closing of the second circulation pipeline 105.

[0094] Specifically, in this embodiment, the two connections between the first pipeline 110 and the first circulation pipeline 102 are located on either side of the PTC module 104 and at two different sections between the PTC module 104 and the range extender assembly 101. The first switching valve 109 is a three-way valve having the following three connection states.

[0095] Among them, in the first connection state, the first switching valve 109 opens the first pipeline 110 and closes the second circulation pipeline 105, so that the first pipeline 110 is connected to the second circulation pipeline 105, and at the same time cuts off the connection between the second circulation pipeline 105 and the range extender assembly 101, so that the heat storage medium in the second circulation pipeline 105 flows directly through the first pipeline 110 to the PTC module 104, and forms a circulation in the first pipeline 110 and the second circulation pipeline 105, so that the battery module 107 can be quickly heated.

[0096] Among them, in the second connection state, the first switching valve 109 closes the first pipeline 110 and opens the second circulation pipeline 105, that is, the connection between the second circulation pipeline 105 and the range extender assembly 101 is maintained, and the heat storage medium in the second circulation pipeline 105 does not need to pass through the first pipeline 110, and is directly circulated from the range extender assembly 101 to the PTC module 104 through the second circulation pipeline 105, thereby achieving heat dissipation of the range extender assembly 101 and heating of the battery module 107.

[0097] Among them, in the third connected state, the first switch valve 109 opens the first pipeline 110 and the second circulation pipeline 105, and part of the heat storage medium in the second circulation pipeline 105 enters the second circulation pipeline 105 through the second outlet port 1012, flows through the PTC module 104 and the first heat exchanger 106, and returns to the range extender assembly 101 through the second inlet port 1015. Part of the heat storage medium flows directly to the PTC module 104 through the first pipeline 110 without passing through the range extender assembly 101, thereby realizing two circulation paths, thereby enabling rapid heat dissipation of the range extender assembly 101 and heating of the battery module 107.

[0098] In addition, by completely closing the first switch valve 109 , the communication with the second circulation pipeline 105 can be cut off, so that the range extender assembly 101 dissipates heat only through the first radiator 103 .

[0099] In this embodiment, there are two first switch valves 109 , which are respectively arranged at the connection between the two ends of the first pipeline 110 and the second circulation pipeline 105 , thereby improving the flexibility and control accuracy of the thermal management system.

[0100] By adopting the above technical solution, the first on-off valve 109 changes the connection state between the first pipeline 110 and the second circulation pipeline 105, achieving different thermal management objectives and improving the applicability of the thermal management system. Furthermore, the first on-off valve 109 can also control the flow rate of the heat storage medium in the first pipeline 110 and the second circulation pipeline 105 to achieve optimal thermal management results.

[0101] In an optional embodiment, the thermal management system also includes a second pipeline 111, both ends of which are respectively connected to the second circulation pipeline 105; a warm air core 112, which is arranged on the second pipeline 111; a second switch valve 113, which is arranged at the connection between the second pipeline 111 and the second circulation pipeline 105, and the second switch valve 113 is configured to control the connection and closing of the second pipeline 111 and the second circulation pipeline 105, as well as the connection or closing of the second circulation pipeline 105.

[0102] Specifically, in this embodiment, the thermal management system also includes a heater core 112 and a second pipeline 111. The two ends of the second pipeline 111 are respectively connected to the second circulation pipeline 105. The heater core 112 is arranged on the second pipeline 111, so that the heat storage medium in the second circulation pipeline 105 can transfer heat to the heater core 112 when flowing through the second pipeline 111, thereby achieving heating of the cockpit.

[0103] Specifically, in this embodiment, both ends of the second pipeline 111 are respectively connected to the second circulation pipeline 105 , so that the heat in the range extender assembly 101 can be transferred to the heater core 112 through the second circulation pipeline 105 .

[0104] At the same time, in this embodiment, the connection between the second pipeline 111 and the second circulation pipeline 105 is located on the same section between the PTC module 104 and the range extender assembly 101, and the second switch valve 113 is a three-way valve with the following three connection states.

[0105] Among them, in the first connected state, the second switch valve 113 opens the second pipeline 111 and closes the second circulation pipeline 105, so that the heat storage medium in the second circulation pipeline 105 flows directly through the second pipeline 111 to the heater core 112 without passing through the first heat exchanger 106, thereby heating the heater core 112 while the range extender assembly 101 dissipates heat, and further heats the heater core 112 through the PTC module 104 to achieve heating of the cockpit, which is suitable for situations where heat dissipation of the battery module 107 is not required.

[0106] Among them, in the second connection state, the second switch valve 113 closes the second pipeline 111 and opens the second circulation pipeline 105, that is, maintains the connection between the PTC module 104 and the first heat exchanger 106, realizes the heat exchange between the range extender assembly 101, the PTC module 104 and the battery module 107, and is suitable for situations where there is no need to heat the cockpit.

[0107] Among them, in the third connected state, the second switch valve 113 opens the second pipeline 111 and the second circulation pipeline 105, while maintaining the heat exchange between the PTC module 104 and the battery module 107, so that the heat of the PTC module 104 can not only heat the heater core 112 through the second pipeline 111, but also be transferred to the battery module 107 through the second circulation pipeline 105, thereby realizing the heating of the battery module 107 and the heater core 112.

[0108] By adopting the above technical solution, the heat of the PTC module 104 and the range extender assembly 101 is transferred to the heater core 112 through the second pipe 111, and the heater core 112 is heated, thereby achieving heating of the cockpit and improving energy utilization.

[0109] In addition, in this embodiment, the thermal management system may further include a first pipeline 110, with both ends of the first pipeline 110 respectively connected to the second circulation pipeline 105. A first on-off valve 109 is disposed at the connection between the first pipeline 110 and the second circulation pipeline 105. By opening and closing the first on-off valve 109, the range extender assembly 101, the PTC module 104, and the heater core 112 can be selectively connected, thereby achieving efficient utilization of waste heat from the range extender assembly 101 and the PTC module 104, achieving cockpit heating without additional energy consumption, and improving energy utilization.

[0110] Specifically, when the first switching valve 109 opens the first pipeline 110 and closes the second circulation pipeline 105, the first pipeline 110 is connected to the second circulation pipeline 105, and the connection between the second circulation pipeline 105 and the range extender assembly 101 is cut off, so that the heat storage medium in the second circulation pipeline 105 flows directly through the first pipeline 110 to the PTC module 104 and flows through the heater core 112, thereby heating the heater core 112 through the PTC module 104.

[0111] When the first switch valve 109 closes the first pipeline 110 and opens the second circulation pipeline 105 , the range extender assembly 101 , the PTC module 104 and the heater core 112 are connected in series, so that the waste heat of the range extender assembly 101 heats the heater core 112 .

[0112] When the first switching valve 109 opens the first pipeline 110 and the second circulation pipeline 105, part of the heat storage medium in the second circulation pipeline 105 passes through the range extender assembly 101 and flows through the PTC module 104 and the heater core 112 in sequence. Part of the heat storage medium circulates between the PTC module 104 and the heater core 112 through the first pipeline 110, thereby increasing the heating efficiency of the heater core 112.

[0113] In an optional embodiment, the range extender assembly 101 has a third outlet port 1013 and a third inlet port 1016 , the third outlet port 1013 and the third inlet port 1016 are connected through a fourth circulation pipeline 114 , and the second radiator 115 is disposed on the fourth circulation pipeline 114 .

[0114] Specifically, in this embodiment, since the range extender assembly 101 generates a large amount of heat during operation, further heat dissipation is performed through the fourth circulation pipeline 114 and the second radiator 115, which can ensure the heat dissipation efficiency of the range extender assembly 101 and avoid excessive load on the first radiator 103.

[0115] Specifically, in this embodiment, the range extender assembly 101 includes an engine, a turbocharger, and an intake manifold. The third outlet port 1013 is located on the turbocharger, and the third inlet port 1016 is located on the intake manifold. When the engine is operating, the high-temperature, high-pressure exhaust gas drives the turbine to rotate. The turbine's rotation in turn drives the compressor, which compresses the ambient air and delivers it into the intake manifold, where it enters the engine. This increases the engine's intake volume and improves its output power. However, direct entry of high-temperature, high-pressure gas into the intake manifold can damage engine components or shorten their lifespan. It can also cause thermal stress on the intake manifold, leading to deformation or cracking.

[0116] Therefore, in this embodiment, the high-temperature and high-pressure gas discharged from the turbocharger enters the second radiator 115 through the fourth circulation pipeline 114 for heat dissipation, and then returns to the intake manifold through the third inlet port 1016 to realize circulation, thereby reducing the thermal stress of the intake manifold and reducing the thermal load of the engine.

[0117] In this embodiment, the second radiator 115 is an intercooler, thereby effectively reducing the intake air temperature of the engine.

[0118] At the same time, it should be noted that in this embodiment, a fan is provided next to the fourth circulation pipeline 114, the first circulation pipeline 102 adopts liquid cooling for heat dissipation, and the fourth circulation pipeline 114 adopts air cooling for heat dissipation, thereby achieving high-efficiency heat dissipation of the range extender assembly 101 through these two methods.

[0119] In an optional embodiment, the thermal management system further includes an evaporator 116 and a condenser 117 , and the evaporator 116 and the condenser 117 are connected via a fifth circulation pipeline 118 .

[0120] Specifically, in this embodiment, the evaporator 116 can convert the refrigerant from liquid to gas and absorb heat in the air, thereby reducing the temperature of the cockpit. The condenser 117 is connected to the evaporator 116 through the fifth circulation pipe 118, so that the gaseous refrigerant is re-condensed into liquid to realize the circulation of the refrigerant.

[0121] In this embodiment, the thermal management system also includes a fan, which is arranged next to the condenser 117. Since the coolant releases heat when condensing in the condenser 117, the fan can assist in cooling the condenser 117 and improve the heat dissipation efficiency of the condenser 117.

[0122] In this embodiment, a circulation pump is further provided on the fifth circulation pipeline 118 , so as to enhance the fluidity and circulation efficiency of the refrigerant in the fifth circulation pipeline 118 .

[0123] Specifically, in this embodiment, an expansion valve is also provided on the fifth circulation pipeline 118, and the expansion valve is arranged close to the evaporator 116, so as to throttle and reduce the pressure of the high-temperature and high-pressure refrigerant condensed by the condenser 117, so that it is converted into a low-temperature and low-pressure vapor-liquid mixture, creating conditions for the evaporation of the refrigerant in the evaporator 116, so that the refrigerant can absorb heat more effectively.

[0124] In an optional embodiment, the thermal management system also includes a third pipeline 119, both ends of which are connected to the fifth circulation pipeline 118; a second heat exchanger 120, which is arranged on the third pipeline 119; and a fourth pipeline 121, both ends of which are respectively connected to the third circulation pipeline 108, and the battery module 107 is connected to the second heat exchanger 120 through the fourth pipeline 121.

[0125] Specifically, in this embodiment, both ends of the third pipeline 119 are connected to the fifth circulation pipeline 118. The two connection points of the third pipeline 119 and the fifth circulation pipeline 118 are respectively located on both sides of the condenser 117 and at two different sections between the evaporator 116 and the condenser 117. The two ends of the fourth pipeline 121 are respectively connected to the third circulation pipeline 108. The two connection points of the fourth pipeline 121 and the third circulation pipeline 108 are respectively located on both sides of the first heat exchanger 106 and at two different sections between the first heat exchanger 106 and the battery module 107. In this way, the heat storage medium flowing out of the battery module 107 is divided into two flow directions along the third circulation pipeline 108 and the fourth pipeline 121. This allows the low-temperature refrigerant in the fifth circulation pipeline 118 to exchange heat with the heat storage medium in the fourth pipeline 121 at the second heat exchanger 120 through the third pipeline 119, thereby achieving heat dissipation of the battery module 107.

[0126] Specifically, in this embodiment, an expansion valve is also provided on the third circulation pipeline 108, and the expansion valve is arranged close to the evaporator 116, so as to throttle and reduce the pressure of the high-temperature and high-pressure refrigerant condensed by the condenser 117, so that it is converted into a low-temperature and low-pressure vapor-liquid mixture, so as to facilitate the refrigerant to exchange heat with the battery module 107 through the second heat exchanger 120.

[0127] In an optional embodiment, the thermal management system further includes a third switching valve 122, which is arranged at the connection between the fourth pipeline 121 and the third circulation pipeline 108, and the third switching valve 122 is configured to control the connection or closing of the fourth pipeline 121 and the connection or closing of the third circulation pipeline 108.

[0128] Specifically, in this embodiment, the third switch valve 122 is a three-way valve having the following two communication states.

[0129] In the first connected state, the third on-off valve 122 opens the fourth pipeline 121 and closes the third circulation pipeline 108, allowing the heat storage medium to circulate between the battery module 107 and the second heat exchanger 120. At this time, since the second heat exchanger 120 is connected to the third pipeline 119, the heat storage medium in the fourth pipeline 121 can exchange heat with the refrigerant in the third pipeline 119 within the second heat exchanger 120, thereby cooling the battery module 107. At the same time, since the third circulation pipeline 108 is closed, the battery module 107 does not exchange heat with the PTC module 104, thereby preventing the heat transferred from the PTC module 104 from affecting the heat dissipation effect of the battery module 107.

[0130] Among them, in the second connection state, the third switch valve 122 closes the fourth pipeline 121 and opens the third circulation pipeline 108, so that the heat storage medium circulates between the battery module 107 and the first heat exchanger 106, and the battery module 107 and the PTC module 104 exchange heat in the first heat exchanger 106, thereby achieving the temperature increase of the battery module 107.

[0131] By adopting the above technical solution, third on-off valve 122 is used to change the connection state between third pipeline 119 and fifth circulation pipeline 118, achieving different thermal management objectives and improving the applicability of the thermal management system. Furthermore, third on-off valve 122 can also control the flow rates of the heat storage medium in third pipeline 119 and the refrigerant in fifth circulation pipeline 118 to achieve optimal thermal management results.

[0132] In addition, the thermal management system may further include a secondary valve, which is a three-way valve located at the connection between the third pipeline 119 and the fifth circulation pipeline 118 and has three connection states.

[0133] In the first connected state, the auxiliary valve opens the third pipeline 119 and closes the fifth circulation pipeline 118, allowing the refrigerant to circulate between the condenser 117 and the second heat exchanger 120. That is, the refrigerant in the fifth circulation pipeline 118 passes through the condenser 117, then enters the second heat exchanger 120 through the third pipeline 119, exchanges heat with the battery module 107, and then returns to the condenser 117 for heat dissipation without passing through the evaporator 116. Therefore, when the cockpit does not need to be cooled, the refrigerant and condenser 117 can dissipate heat from the battery module 107.

[0134] Among them, in the second connection state, the auxiliary valve closes the third pipeline 119 and opens the fifth circulation pipeline 118, so that the refrigerant in the fifth circulation pipeline 118 circulates in the fifth circulation pipeline 118, that is, circulates between the evaporator 116 and the condenser 117, to achieve cooling of the cockpit, which is suitable for situations where the battery module 107 does not need to be cooled.

[0135] Among them, in the third connection state, the auxiliary valve opens the third pipeline 119 and the fifth circulation pipeline 118, and part of the refrigerant enters the second heat exchanger 120 through the third pipeline 119 to exchange heat with the battery module 107, and then returns to the condenser 117 to dissipate heat, and the other part of the refrigerant enters the evaporator 116 to cool the cockpit, thereby achieving heat dissipation for the battery module 107 while cooling.

[0136] In an optional embodiment, the thermal management system further includes an integrated electric drive bridge module 123 and a high-voltage accessory module 124 , the integrated electric drive bridge module 123 and the high-voltage accessory module 124 are connected via a sixth circulation pipeline 125 , and a third radiator 126 is disposed on the sixth circulation pipeline 125 .

[0137] Specifically, the integrated electric drive bridge module 123 and the high-voltage accessory module 124 will generate a large amount of heat during operation. In order to ensure that the integrated electric drive bridge module 123 and the high-voltage accessory module 124 are always at a stable operating temperature, the heat storage medium in the sixth circulation pipeline 125 is allowed to flow through the integrated electric drive bridge module 123 and the high-voltage accessory module 124 to take away the heat generated during their operation, and the heat is dissipated through the third radiator 126, thereby ensuring the normal operation of the integrated electric drive bridge module 123 and the high-voltage accessory module 124.

[0138] In an optional embodiment, the sixth circulation pipeline 125 includes a main line 1251, a first branch 1252 and a second branch 1253, the first branch 1252 is connected to the integrated electric drive bridge module 123, the second branch 1253 is connected to the high-voltage accessory module 124, the main line 1251 is connected to the first branch 1252 and the second branch 1253, and the third radiator 126 is arranged on the main line 1251.

[0139] Specifically, in this embodiment, the first branch 1252 is connected to the integrated electric drive bridge module 123, the second branch 1253 is connected to the high-voltage accessory module 124, and the main line 1251 is connected to the first branch 1252 and the second branch 1253, thereby realizing the parallel connection of the integrated electric drive bridge module 123 and the high-voltage accessory module 124, ensuring the independence of the integrated electric drive bridge module 123 and the high-voltage accessory module 124 during heat dissipation, and avoiding the mutual influence of the heat generated by the integrated electric drive bridge module 123 and the high-voltage accessory module 124.

[0140] Specifically, in this embodiment, control valves and water pumps are installed on both the first branch 1252 and the second branch. The control valves adjust the flow of the thermal storage medium according to actual needs. When the cooling demand of a module increases, the corresponding control valve opens wider, allowing more thermal storage medium to flow through that module. Conversely, when the cooling demand decreases, the control valve opens more narrowly, restricting the flow of thermal storage medium. In this way, the system can achieve separate and precise control of the cooling needs of different modules.

[0141] At the same time, the setting of the water pump can ensure the smooth flow of the heat storage medium in the first branch 1252 and the second branch 1253. The speed and power of the water pump can also be adjusted as needed to match the cooling requirements under different working conditions.

[0142] In a second aspect, this embodiment provides a vehicle, comprising a vehicle body and a thermal management system as described in any one of the first aspects, wherein the thermal management system is disposed in the vehicle body.

[0143] The thermal management system has been described in the above embodiments and will not be repeated here.

[0144] The vehicle provided in this embodiment includes a vehicle body and the thermal management system described in any one of the first aspects, wherein the thermal management system is arranged in the vehicle body, wherein the thermal management system includes a range extender assembly 101, having a first outlet port 1011, a second outlet port 1012, a first inlet port 1014 and a second inlet port 1015, the first outlet port 1011 and the first inlet port 1014 being connected through a first circulation pipeline 102; a first radiator 103, arranged on the first circulation pipeline 102; a PTC module 104, connected to the range extender assembly 101 through a second circulation pipeline 105, and the two ends of the second circulation pipeline 105 are respectively connected to the second outlet port 1012 and the second inlet port 1015; a first heat exchanger 106, arranged on the second circulation pipeline 105; and a battery module 107, connected to the first heat exchanger 106 through a third circulation pipeline 108, and the third circulation pipeline 108 is respectively connected to the two ends of the battery module 107. The range extender assembly 101 can dissipate heat through the first radiator 103. Simultaneously, the battery module 107 is used to power the PTC module 104, causing it to generate heat. Since the battery module 107 is connected to the first heat exchanger 106 via the third circulation line 108, heat can be exchanged between the first heat exchanger 106 and the PTC module 104, transferring the heat generated by the PTC module 104 to the battery module 107. This heat is then heated by the PTC module 104, thereby achieving efficient energy utilization and avoiding energy waste.

[0145] In addition, the heat generated by the range extender assembly 101 can also be exchanged with the battery module 107 through the first heat exchanger 106 on the second circulation pipeline 105, thereby achieving heat dissipation of the range extender assembly 101 and heating of the battery module 107 at the same time.
