[0073] In some embodiments, as shown in Figures 1-8 , Figure 11 As shown, the refrigerant circuit 10 is provided with a fourth branch 87, one end of the fourth branch 87 is located between the evaporator 12 and the gas-liquid separator 15, and the other end of the fourth branch 87 is located between the exhaust port 112 and the condenser 13, the fourth branch 87 is provided with a first expansion valve 81, and the exhaust port 112 and the condenser 13 are provided with a second expansion valve 82. For example, at least one of the first expansion valve 81 and the second expansion valve 82 is an electronic expansion valve.

[0074] Thus, the liquid accumulated in the gas-liquid separator 15 can enter the compressor 11 from the suction port 111, and the high-temperature and high-pressure refrigerant compressed by the compressor 11 can flow into the fourth branch 87 through the first expansion valve 81, and the refrigerant flowing out of the first expansion valve 81 can be fully mixed with the liquid in the gas-liquid separator 15 and flow out of the suction port 111 to flow into the compressor 11 together, thereby forming a hot gas bypass circulation, achieving sufficient heat exchange, improving heat exchange efficiency, and enabling the heat-exchanged refrigerant to meet the required heating demand and meet the low-temperature heating requirement.

[0075] In some embodiments, as shown in Figures 1-11 The heat management system 100 further includes an air conditioning box 86, the evaporator 12 and the heater core 253 are located in the air conditioning box 86, and the air conditioning box 86 is located in the cockpit, and the cooling, heating and other requirements of the cockpit can be achieved by controlling the evaporator 12 and the heater core 253 respectively.

[0076] In some embodiments of the present application, as shown in Figures 1-11 The condenser 13 includes a third heat exchange passage and a fourth heat exchange passage, the third heat exchange passage is connected in series on the refrigerant circuit 10, and the third heat exchange passage is located between the evaporator 12 and the exhaust port 112, the fifth passage 25 is further provided with a second branch 254, the two ends of the second branch 254 are in communication with the two ends of the heater core 253 respectively, the fourth heat exchange passage is connected in series on the second branch 254, heat exchange is achieved through the third heat exchange passage and the fourth heat exchange passage, thereby achieving heat exchange between the refrigerant circuit 10 and the fifth passage 25, and achieving heat exchange between the cooling liquid circuit 20 and the refrigerant circuit 10, thereby meeting the required heat exchange demand, such as achieving the requirement of discharging waste heat by the third heat exchange passage or achieving the requirement of heat absorption by the third heat exchange passage, and the structure is simple, thereby reducing the production cost.

[0077] In some embodiments, as shown in Figures 1-11 A second water pump 256 is arranged on the second branch 254, which facilitates the flow of the cooling liquid in the second branch 254 to meet the required driving requirement and realize the circulation of the cooling liquid in the fourth heat exchange channel, and the structure is simple and the production cost can be reduced.

[0078] According to some embodiments of the present application, as shown in Figure 1 As shown in Figure 2 In the first state, the first passage 21 and the second passage 22 form a first sub-circuit 61 through the first control valve 41, and the third passage 23, the fourth passage 24 and the fifth passage 25 form a second sub-circuit 62 through the first control valve 41, which can realize the required communication circuit and meet the required heat exchange requirement. At the same time, the eleventh valve port 421 is selectively communicated with at least one of the twelfth valve port 422 and the thirteenth valve port 423, which can form a large circulation of the third passage 23, the fourth passage 24 and the fifth passage 25, or can subdivide the third passage 23, the fourth passage 24 and the fifth passage 25 into small circulations, or can adjust the water mixing ratio between the small circulations, so as to realize different heat distribution requirements.

[0079] In some embodiments, as shown in Figure 1 As shown in Figure 2 In the first state, the first port 211 and the first valve port 51 are communicated, the second port 212 and the second valve port 52 are communicated, the third port 221 and the third valve port 53 are communicated, the fourth port 222 and the fourth valve port 54 are communicated, the fifth port 231 and the fifth valve port 55 are communicated, the sixth port 232 and the sixth valve port 56 are communicated, the seventh port 241 and the seventh valve port 57 are communicated, the eighth port 242 and the eighth valve port 58 are communicated, the ninth port 251 and the ninth valve port 59 are communicated, and the tenth port 252 and the tenth valve port 510 are communicated, so that the first sub-circuit 61 and the second sub-circuit 62 are formed inside the cooling liquid circuit 20, that is, the first passage 21 and the second passage 22 are communicated through the first control valve 41 to form the first sub-circuit 61, and the third passage 23, the fourth passage 24 and the fifth passage 25 are communicated through the first control valve 41 to form the second sub-circuit 62, which can realize the required communication circuit and meet the required heat exchange requirement.

[0080] At the same time, as shown in Figure 1 As shown in Figure 2As shown, the third passage 23, the fourth passage 24 and the fifth passage 25 can be formed into a large circulation, or can be subdivided into small circulations, or can adjust the water mixing ratio between the small circulations, so as to realize different heat distribution requirements, by the eleventh valve port 421 being selectively communicated with at least one of the twelfth valve port 422 and the thirteenth valve port 423.

[0081] For example, in some embodiments, as Figure 2 As shown, when the first state includes heating the passenger compartment and the battery cooler 213 is cooling, the eleventh valve port 421 is communicated with the twelfth valve port 422 and disconnected with the thirteenth valve port 423, the first passage 21 and the second passage 22 are in series, so that the battery cooler 213 and the second heat exchange channel 32 are in series, part of the third passage 23, the fourth passage 24 and the fifth passage 25 are in series, so that the first radiator 233 and the electric drive assembly 243 are in series, the fourth heat exchange channel and the heater core 253 are in series, and the compressor 11 is turned on.

[0082] Therefore, the heat absorbed by the battery cooler 213 can be transmitted to the second heat exchange channel 32 through the cooling liquid in the first passage 21 and the second passage 22, the second heat exchange channel 32 and the first heat exchange channel 31 exchange heat, realize the cooling of the battery cooler 213, at the same time, the cooling liquid absorbs heat from the refrigerant, the refrigerant in the first heat exchange channel 31 enters the third heat exchange channel of the condenser 13 through the compressor 11, so that the refrigerant in the third heat exchange channel can exchange heat with the cooling liquid in the fourth heat exchange channel, increase the temperature of the cooling liquid, and the cooled cooling liquid can flow through the heater core 253, realize the heating of the passenger compartment, meet the required use requirements, and the cooling liquid flows between part of the third passage 23, the fourth passage 24 and the fifth passage 25, so that the electric drive assembly 243 can be cooled through the first radiator 233, realize the cooling requirement of the electric drive assembly 243.

[0083] In addition, as Figure 2 As shown, by controlling the eleventh valve port 421 to be communicated with the twelfth valve port 422 and the thirteenth valve port 423, and adjusting the opening ratio of the second control valve 42, the third passage 23, the fourth passage 24 and the fifth passage 25 are communicated, so that the excess heat (i.e. the remaining heat after removing the heat required by the heater core 253) absorbed by the cooling liquid from the battery cooler 213 can be released to the first radiator 233 through the fifth passage 25 into the third passage 23 and the fourth passage 24, meet the required cooling requirement.

[0084] In some embodiments, as Figures 1-11As shown, a third control valve 71 is provided on the first branch 14. The third control valve 71 is located between the condenser 13 and the first heat exchange channel 31. The third control valve 71 can control whether the refrigerant flows through the first heat exchange channel 31, thereby controlling whether the first heat exchange channel 31 and the second heat exchange channel 32 exchange heat, and meeting the required control requirements.

[0085] In some embodiments, such as Figures 1-11 As shown, a fourth control valve 72 is provided between one end of the first branch 14 and the evaporator 12. The fourth control valve 72 can control whether the refrigerant flows through the evaporator 12, thereby controlling whether the evaporator 12 works and meeting the required control requirements.

[0086] In some embodiments, such as Figures 1-11 As shown, a one-way valve 83 is also provided on the refrigerant circuit 10. The one-way valve 83 is located between the evaporator 12 and the other end of the first branch 14. The one-way valve 83 is used to control the refrigerant to flow only from the evaporator 12 to the compressor 11, and can prevent the refrigerant flowing out of the first heat exchange channel 31 from flowing through the evaporator 12 and affecting the normal operation of the thermal management system 100.

[0087] For example, in some embodiments, such as Figure 1 As shown, in the first state including the crew compartment cooling, the eleventh valve port 421 is connected to the thirteenth valve port 423 and disconnected from the twelfth valve port 422. The first passage 21 and the second passage 22 are connected in series, so that the battery cooler 213 and the second heat exchange channel 32 are connected in series. The third passage 23, the fourth passage 24 and the second branch 254 are connected in series, so that the first radiator 233, the electric drive assembly 243 and the fourth heat exchange channel are connected in series. The compressor 11 is turned on, the third control valve 71 is closed and the fourth control valve 72 is opened.

[0088] Thus, refrigerant can enter the compressor 11 from the intake port 111, and after being compressed by the compressor 11, it can flow out from the exhaust port 112, flow through the third heat exchange channel for condensation, and the condensed refrigerant enters the evaporator 12 through the fourth control valve 72 to evaporate and absorb heat, thus meeting the cooling needs of the passenger compartment. Then, it enters the compressor 11 through the intake port 111, completing the cycle. At the same time, the coolant in the fourth heat exchange channel, after exchanging heat with the third heat exchange channel, flows through the second branch 254 and the third passage 23 to the first radiator 233 for heat dissipation, and the coolant flowing through the electric drive assembly 243 can flow through the fourth passage 24 to the fifth passage 25, thus meeting the heat dissipation needs of the electric drive assembly 243 and satisfying the required operating requirements.

[0089] For example, in some embodiments, such as Figure 1As shown, in the first state including refrigeration of the battery through the battery cooler 213, the eleventh valve port 421 is in communication with the thirteenth valve port 423 and disconnected from the twelfth valve port 422, the first passage 21 and the second passage 22 are in series, so that the battery cooler 213 and the second heat exchange channel 32 are in series, the third passage 23, the fourth passage 24 and the second branch 254 are in series, so that the first radiator 233, the electric drive assembly 243 and the fourth heat exchange channel are in series, the compressor 11 is turned on, and the third control valve 71 is opened and the fourth control valve 72 is closed.

[0090] Thus, the refrigerant can enter the compressor 11 from the suction port 111, the refrigerant compressed by the compressor 11 can flow out from the exhaust port 112, flow through the third heat exchange channel for condensation, and the condensed refrigerant enters the first heat exchange channel 31 through the third control valve 71, the first heat exchange channel 31 can exchange heat with the second heat exchange channel 32, the heat-exchanged refrigerant enters the compressor 11 through the suction port 111, and the cycle is completed. The cooling liquid in the second heat exchange channel 32 exchanges heat with the refrigerant in the first heat exchange channel 31 and then flows through the battery cooler 213 to cool the battery cooler 213, and the cooling liquid in the fourth heat exchange channel exchanges heat with the refrigerant in the third heat exchange channel and then flows through the second branch 254 and the third passage 23 to the first radiator 233 for heat dissipation, and the cooling liquid flowing through the electric drive assembly 243 can flow to the fifth passage 25 through the fourth passage 24 to meet the heat dissipation requirements of the electric drive assembly 243 and meet the required working requirements.

[0091] For example, in some embodiments, as Figure 1 As shown, in the first state including refrigeration of the battery through the battery cooler 213, the eleventh valve port 421 is in communication with the thirteenth valve port 423 and disconnected from the twelfth valve port 422, the first passage 21 and the second passage 22 are in series, so that the battery cooler 213 and the second heat exchange channel 32 are in series, the third passage 23, the fourth passage 24 and the second branch 254 are in series, so that the first radiator 233, the electric drive assembly 243 and the fourth heat exchange channel are in series, the compressor 11 is turned on, and the third control valve 71 and the fourth control valve 72 are opened.

[0092] Thus, the refrigerant can enter the compressor 11 from the suction port 111, the refrigerant compressed by the compressor 11 can flow out from the exhaust port 112, flow through the third heat exchange channel to be condensed, and part of the condensed refrigerant enters the evaporator 12 to be evaporated and absorb heat through the fourth control valve 72, so as to realize the refrigeration demand of the passenger compartment, and the other part of the condensed refrigerant enters the first heat exchange channel 31 through the third control valve 71, the first heat exchange channel 31 can exchange heat with the second heat exchange channel 32, and then the heat-exchanged refrigerant enters the compressor 11 through the suction port 111, and the cycle is completed. At the same time, the cooling liquid in the second heat exchange channel 32 exchanges heat with the refrigerant in the first heat exchange channel 31, and then flows through the battery cooler 213 to cool the battery cooler 213, and the cooling liquid in the fourth heat exchange channel exchanges heat with the refrigerant in the third heat exchange channel, and then flows through the second branch 254 and the third passage 23 to the first radiator 233 to dissipate heat, and the cooling liquid flowing through the electric drive assembly 243 can flow to the fifth passage 25 through the fourth passage 24 to realize the heat dissipation demand of the electric drive assembly 243, and meet the required working demand.

[0093] In some embodiments of the present application, as shown in Figure 9 With Figure 10 As shown, the second branch 254 is provided with a heater 255, which can directly heat the heater core 253, avoiding heating the heater core 253 through the refrigerant circuit 10 and the cooling liquid circuit 20, so as to avoid the problem that the heater core 253 cannot work normally when the refrigerant circuit 10 is abnormal due to low ambient temperature, and can meet different use requirements.

[0094] According to some embodiments of the present application, as shown in Figures 3-5 As shown, in the second state, the second passage 22 and the third passage 23 form a third sub-circuit 63 through the first control valve 41, and the fourth passage 24, the fifth passage 25 and the first passage 21 form a fourth sub-circuit 64 through the first control valve 41, which can realize the required communication circuit and meet the required heat exchange demand. At the same time, the eleventh valve port 421 is selectively communicated with at least one of the twelfth valve port 422 and the thirteenth valve port 423, which can make the fourth passage 24, the fifth passage 25 and the first passage 21 form a large circulation, or can subdivide the fourth passage 24, the fifth passage 25 and the first passage 21 into small circulations, or can adjust the water mixing ratio between the small circulations, so as to realize different heat distribution requirements.

[0095] In some embodiments, as shown in Figures 3-5As shown, in the second state, the first port 211 is connected to the ninth valve port 59, the second port 212 is connected to the tenth valve port 510, the third port 221 is connected to the first valve port 51, the fourth port 222 is connected to the second valve port 52, the fifth port 231 is connected to the third valve port 53, the sixth port 232 is connected to the fourth valve port 54, the seventh port 241 is connected to the fifth valve port 55, the eighth port 242 is connected to the sixth valve port 56, the ninth port 251 is connected to the seventh valve port 57, and the tenth port 252 is connected to the eighth valve port 58, so that the coolant circuit 20 forms a third sub-circuit 63 and a fourth sub-circuit 64. That is, the second passage 22 and the third passage 23 are formed into the third sub-circuit 63 through the first control valve 41, and the fourth passage 24, the fifth passage 25 and the first passage 21 are formed into the fourth sub-circuit 64 through the first control valve 41, so as to realize the required connected circuit and meet the required heat exchange requirements.

[0096] At the same time, such as Figures 3-5 As shown, the eleventh valve port 421 can be selectively connected to at least one of the twelfth valve port 422 and the thirteenth valve port 423, which can enable the fourth passage 24, the fifth passage 25 and the first passage 21 to form a large loop, or to subdivide the fourth passage 24, the fifth passage 25 and the first passage 21 into small loops, or to adjust the mixing ratio between the small loops, thereby achieving different heat distribution requirements.

[0097] For example, in some embodiments, such as Figure 3 As shown, in the second state, including crew cabin heating and battery heating via battery cooler 213, eleventh valve port 421 is connected to twelfth valve port 422 and disconnected from thirteenth valve port 423. Second passage 22 and third passage 23 are connected in series, so that second heat exchange channel 32 and first radiator 233 are connected in series. Parts of first passage 21, fourth passage 24 and fifth passage 25 are connected in series, so that electric drive assembly 243 and battery cooler 213 are connected in series. Fourth heat exchange channel and heater core 253 are connected in series, and compressor 11 is turned on.

[0098] Thus, the cooling liquid in the first radiator 233 can absorb heat from the air, and the cooling liquid after absorbing the heat can flow through the third circuit and the second circuit to transfer the heat to the first heat exchange channel 31 through the second heat exchange channel 32, so as to transfer the heat of the cooling liquid to the refrigerant in the refrigerant circuit 10, the refrigerant in the first heat exchange channel 31 can flow through the compressor 11 and the third heat exchange channel, the refrigerant in the third heat exchange channel can exchange heat with the cooling liquid in the fourth heat exchange channel, so that the cooling liquid after absorbing the heat can flow through the warm air core 253 to realize heating of the passenger compartment, meet the required use demand, and the cooling liquid flows between the parts of the fourth passage 24, the first passage 21 and the fifth passage 25, so that the waste heat of the electric drive assembly 243 can be transferred to the battery cooler 213 to realize the heating demand of the battery.

[0099] In addition, as shown in Figure 3 , the control eleventh valve port 421 communicates with the twelfth valve port 422 and the thirteenth valve port 423, by adjusting the opening ratio of the second control valve 42, so that the first passage 21, the fourth passage 24 and the fifth passage 25 are communicated, the cooling liquid in the fourth heat exchange channel after heat exchange can be transferred to the battery cooler 213 through the second branch 254, the cooling liquid can be mixed, the heating demand of the battery can be realized, and different control demands can be realized.

[0100] For example, in some embodiments, as shown in Figure 4 , when the second state includes heating of the battery through the battery cooler 213, the eleventh valve port 421 communicates with the thirteenth valve port 423 and is disconnected with the twelfth valve port 422, the second passage 22 and the third passage 23 are connected in series, the second heat exchange channel 32 and the first radiator 233 are connected in series, the first passage 21, the fourth passage 24 and the fifth passage 25 are connected in series, the electric drive assembly 243, the battery cooler 213 and the fourth heat exchange channel are connected in series, and the compressor 11 is turned on.

[0101] Thus, the cooling liquid in the first radiator 233 can absorb heat from the air, and the cooling liquid after absorbing the heat can flow through the third circuit and the second circuit to transfer the heat to the first heat exchange channel 31 through the second heat exchange channel 32, so as to transfer the heat of the cooling liquid to the refrigerant in the refrigerant circuit 10, the refrigerant in the first heat exchange channel 31 can flow through the compressor 11 and the third heat exchange channel, the refrigerant in the third heat exchange channel can exchange heat with the cooling liquid in the fourth heat exchange channel, so that the cooling liquid after absorbing the heat can flow through the electric drive assembly 243, realize the heating of the electric drive assembly 243, and the waste heat of the electric drive assembly 243 can be transferred to the battery cooler 213 to realize the heating of the battery.

[0102] In some embodiments of the utility model, as shown in Figures 1-7 , Figure 10 , Figure 11As shown, the cooling liquid circuit 20 further comprises a sixth passage 26, and the sixth passage 26 is provided with an engine 261. By providing the engine 261 on the sixth passage 26, the heat management system 100 can be applied to extended-range vehicles or hybrid vehicles, so that the heat management system 100 has high compatibility. When the heat management system 100 is applied to pure electric vehicles, only the structure corresponding to the sixth passage 26 needs to be removed, so that the heat management system 100 is compatible with pure electric vehicles, extended-range vehicles and hybrid vehicles at the same time, and has simple structure, high reliability and low production cost.

[0103] In addition, as shown in Figures 1-7 , Figure 10 , Figure 11 , the cooling liquid circuit 20 further comprises a fifth control valve 73 for controlling the communication between the sixth passage 26 and the fifth passage 25, so as to control the communication and disconnection between the fourth heat exchange channel and the sixth passage 26, thereby meeting the control requirements of the cooling liquid circuit 20, and the heat management system 100 has high energy efficiency, for example, improving the cruising range of pure electric vehicles.

[0104] In some embodiments in which the second branch 254 is provided with a heater 255, as shown in Figure 10 , the fourth heat exchange channel and the heater 255 can be concentrated on the second branch 254, i.e., the fourth heat exchange channel and the heater 255 are located on the same branch, so as to be conveniently managed, so that the sixth passage 26 and the second branch 254 are conveniently connected, and different control requirements can be met.

[0105] In some embodiments, as shown in Figures 1-7 , Figure 10 , Figure 11 , the sixth passage 26 is further provided with a third branch 263, the two ends of the third branch 263 are in communication with the two ends of the engine 261 respectively, and the third branch 263 is provided with a second radiator 262. The second radiator 262 can dissipate heat of the engine 261, meet the heat dissipation requirements of the engine 261, and be beneficial to prolong the service life of the engine 261.

[0106] In some embodiments, as shown in Figures 1-7 , Figure 10 , Figure 11 , the sixth passage 26 is provided with a third water pump 264. The third water pump 264 can drive the cooling liquid in the sixth passage 26 to flow, meet the required driving requirements, realize the circulation of the cooling liquid in the engine 261, and has simple structure, which can reduce the production cost.

[0107] In some embodiments, as shown in Figures 1-7 , Figure 10 , Figure 11As shown, the thermostat 265 is arranged between the engine 261 and the second radiator 262, and the thermostat 265 can realize the required temperature adjustment requirement in the sixth passage 26, so as to facilitate control.

[0108] According to some embodiments of the present application, as shown in Figure 6 As shown, in the third state, the third passage 23, the fourth passage 24 and the fifth passage 25 form the fifth sub-circuit 65 through the first control valve 41 and the sixth passage 26, so as to realize the required communication circuit and meet the required heat exchange requirement. At the same time, the eleventh valve port 421 is selectively communicated with at least one of the twelfth valve port 422 and the thirteenth valve port 423, so as to form a large circulation of the third passage 23, the fourth passage 24 and the fifth passage 25, or to subdivide the third passage 23, the fourth passage 24 and the fifth passage 25 into small circulations, or to adjust the water mixing ratio between the small circulations, so as to realize different heat distribution requirements.

[0109] In some embodiments, as shown in Figure 6 As shown, in the third state, the fifth port 231 and the fifth valve port 55 are communicated, the sixth port 232 and the sixth valve port 56 are communicated, the seventh port 241 and the seventh valve port 57 are communicated, the eighth port 242 and the eighth valve port 58 are communicated, the ninth port 251 and the ninth valve port 59 are communicated, the tenth port 252 and the tenth valve port 510 are communicated, the eleventh valve port 421 and the thirteenth valve port 423 are communicated, and the sixth passage 26 and the fifth passage 25 are communicated, so as to form the fifth sub-circuit 65 inside the cooling liquid circuit 20, that is, to make the third passage 23, the fourth passage 24 and the fifth passage 25 communicated through the first control valve 41 to form the fifth sub-circuit 65, so as to realize the required communication circuit and meet the required heat exchange requirement.

[0110] In some embodiments, as shown in Figures 1-7 , Figure 10 , Figure 11 As shown, the sixth passage 26 has a fourteenth valve port 731 and a seventeenth valve port 734, and the fourteenth valve port 731 and the seventeenth valve port 734 are respectively located at two ends of the engine 261. The fifth passage 25 has a fifteenth valve port 732 and a sixteenth valve port 733, and the fifteenth valve port 732 and the sixteenth valve port 733 are respectively located at two ends of the heater core 253. The fourteenth valve port 731 is selectively communicated with one of the seventeenth valve port 734 or the fifteenth valve port 732, and the sixteenth valve port 733 is selectively communicated with the other one of the seventeenth valve port 734 and the fifteenth valve port 732, so as to facilitate control of the flow path, control of the communication and disconnection between the fourth heat exchange passage and the sixth passage 26, convenient control, simple structure and reduced production cost.

[0111] For example, in some embodiments, as shown in Figure 5As shown, in the second state including passenger compartment heating and / or battery heating by the battery cooler 213, the second passage 22 and the third passage 23 are in series, so that the second heat exchange channel 32 and the first radiator 233 are in series, the first passage 21, the fourth passage 24 and the fifth passage 25 are in series, so that the electric drive assembly 243, the battery cooler 213 and the fourth heat exchange channel are in series, the fourteenth valve port 731 is in communication with the fifteenth valve port 732, and the sixteenth valve port 733 is in communication with the seventeenth valve port 734, so that the sixth passage 26 is in series with the fifth passage 25.

[0112] When the eleventh valve port 421 is in communication with the twelfth valve port 422 and disconnected from the thirteenth valve port 423, the waste heat of the engine 261 can flow through the heating core 253 through the sixth passage 26 and the fifth passage 25 to meet the heating demand of the passenger compartment, and the waste heat of the motor can heat the battery through the fourth passage 24 and the first passage 21; when the eleventh valve port 421 is in communication with the thirteenth valve port 423 and the twelfth valve port 422, the waste heat of the engine 261 can flow through the heating core 253 through the sixth passage 26 and the fifth passage 25 to meet the heating demand of the passenger compartment, and the waste heat of the engine 261 can flow through the battery cooler 213 through the fifth passage 25 and the first passage 21 to simultaneously heat the battery.
