[0026] The beneficial effects of the embodiments of the present application compared with the prior art are:

[0027] When the vehicle is in a charging state (i.e., the battery pack is in a charging state), if the temperature of the battery pack is too low, the battery pack will send a heating request to the control unit. After receiving the heating request sent by the battery pack, the control unit controls the driving motor to send an electricity consumption request to the battery pack. After receiving the electricity consumption request sent by the driving motor, a pulsed current is generated inside the battery pack. Due to the relatively large internal resistance of the battery pack in a low-temperature environment, heat will be generated in the battery pack under the action of the pulsed current, realizing the heating of the battery pack.

[0028] When the vehicle is in a driving state (i.e., the battery pack is in a discharging state), if the temperature of the battery pack is too low, the battery pack will send a heating request to the control unit. After receiving the heating request sent by the battery pack, control the compressor to operate for heating. The high-temperature refrigerant output by the compressor can enter the first heat exchanger through the first electronic expansion valve or enter the first heat exchanger through the second heat exchanger, and the high-temperature refrigerant releases heat in the first heat exchanger. The heating water in the first heating unit absorbs heat in the first heat exchanger, and the control unit controls the first water pump to transport the heated water to the battery pack to heat the battery pack.

[0029] The temperature control system provided by the embodiment of the present application does not require a high-power PTC heater when heating the battery pack, which can reduce the power consumption of the electric vehicle and help improve the cruising range of the electric vehicle.

[0030] It can be understood that the beneficial effects of the above-mentioned second aspect and third aspect can be referred to the relevant descriptions in the above-mentioned first aspect, and will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Reference to "one embodiment" or "some embodiments" or the like described in the specification of this application means that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of this application. Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments", etc. that appear in different places in this specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in another way.

[0044] As Figure 1As shown in the figure, the temperature control system includes a first heating unit 10, a heating unit 20, and a control unit 30. The first heating unit 10 includes a first water pump 101, a first heat exchanger 102, and a battery pack 40. The first water pump 101, the battery pack 40, and the first heat exchanger 102 are connected in sequence to form a first heating circulation loop. The heating unit 20 includes a compressor 201, a second heat exchanger 202, and a first electronic expansion valve 203. The compressor 201, the second heat exchanger 202, and the first heat exchanger 102 are connected in sequence to form a first heating circulation loop. The compressor 201, the first electronic expansion valve 203, and the first heat exchanger 102 are connected in sequence to form a second heating circulation loop. The control unit 30 is electrically connected to the first water pump 101, the compressor 201, and the first electronic expansion valve 203 respectively.

[0045] Specifically, when the vehicle is in the charging state (i.e., the battery pack 40 is in the charging state), if the temperature of the battery pack 40 is too low, the battery pack 40 will send a heating request to the control unit 30. After receiving the heating request sent by the battery pack 40, the control unit 30 controls the drive motor to send a power consumption request to the battery pack 40. After receiving the power consumption request sent by the drive motor, a pulsed current is generated inside the battery pack 40. Due to the large internal resistance of the battery pack 40 in a low-temperature environment, heat will be generated in the battery pack 40 under the action of the pulsed current, realizing the heating of the battery pack 40.

[0046] When the vehicle is in the driving state (i.e., the battery pack 40 is in the discharging state), if the temperature of the battery pack 40 is too low, the battery pack 40 will send a heating request to the control unit 30. After receiving the heating request sent by the battery pack 40, the control unit 30 controls the compressor 201 and the first water pump 101 to work, and controls the first electronic expansion valve 203 to open. The compressor 201 compresses and does work on the refrigerant, outputting high-temperature refrigerant. The high-temperature refrigerant can enter the first heat exchanger 102 through the first electronic expansion valve 203, or can enter the first heat exchanger 102 through the second heat exchanger 202. The high-temperature refrigerant releases heat in the first heat exchanger 102. The heating water in the first heating unit 10 absorbs heat in the first heat exchanger 102. The control unit 30 controls the first water pump 101 to transport the heated water to the battery pack 40 to heat the battery pack 40.

[0047] It should be noted that the control unit 30 can be an ECU (Electronic Control Unit, vehicle computer) on the vehicle. The control unit 30 can control the rotation speeds of the compressor 201 and the first water pump 101 according to the specific parameters of the heating request of the battery pack 40, and adjust the opening degree of the first electronic expansion valve 203 to meet the heating requirements of the battery pack 40.

[0048] The temperature control system provided by the embodiment of the present application does not require a high-power PTC heater when heating the battery pack 40, which can reduce the power consumption of the electric vehicle and help improve the driving range of the electric vehicle.

[0049] As Figure 2 shown, the heating unit 20 further includes a second electronic expansion valve 204. The second electronic expansion valve 204 is connected in series between the first heat exchanger 102 and the second heat exchanger 202, and the second electronic expansion valve 204 is electrically connected to the control unit 30.

[0050] Specifically, when the vehicle is in a driving state, if the control unit 30 receives a heating request sent by the battery pack 40, the control unit 30 controls the compressor 201 and the first water pump 101 to work, and controls the first electronic expansion valve 203 and the second electronic expansion valve 204 to open. The compressor 201 compresses and does work on the refrigerant, outputting high-temperature refrigerant. The high-temperature refrigerant can enter the first heat exchanger 102 through the first electronic expansion valve 203, or can enter the first heat exchanger 102 through the second heat exchanger 202 and the second electronic expansion valve 204. The high-temperature refrigerant releases heat in the first heat exchanger 102. The heating water in the first heating unit 10 absorbs heat in the first heat exchanger 102, and the control unit 30 controls the first water pump 101 to transport the heated water to the battery pack 40 to heat the battery pack 40.

[0051] The control unit 30 controls the rotation speeds of the compressor 201 and the first water pump 101 according to the specific parameters of the heating request of the battery pack 40, and adjusts the opening degrees of the first electronic expansion valve 203 and the second electronic expansion valve 204 to meet the heating requirements of the battery pack 40.

[0052] As Figure 2 shown, the heating unit 20 further includes a stop valve 205. The stop valve 205 is connected in series between the second electronic expansion valve 204 and the second heat exchanger 202, and the stop valve 205 is electrically connected to the control unit 30.

[0053] Specifically, when it is necessary to turn on the compressor 201 to heat for the battery pack 40, the control unit 30 can control the stop valve 205 to open. At this time, the high-temperature refrigerant output by the compressor 201 can enter the first heat exchanger 102 through the second heat exchanger 202, the first electronic expansion valve 203 and the second stop valve. The high-temperature refrigerant releases heat in the first heat exchanger 102 to provide heat for the first heating unit 10 to heat the battery pack 40.

[0054] When it is not necessary to turn on the compressor 201 to heat for the battery pack 40, the control unit 30 controls the stop valve 205 to close. At this time, the refrigerant cannot circulate in the heating cycle loop.

[0055] AsFigure 3 As shown, the temperature control system further includes a second heating unit 50. The second heating unit 50 includes a warm air core 501 and a second water pump 502. The second water pump 502, the warm air core 501, and the second heat exchanger 202 are connected in sequence to form a second heating circulation loop. The second water pump 502 is electrically connected to the control unit 30.

[0056] Specifically, when the vehicle is in a charging state or a driving state, the passenger compartment can send a heating request to the control unit 30. When the control unit 30 receives the heating request sent by the passenger compartment, the control unit 30 controls the compressor 201 to generate heat. The high-temperature refrigerant output by the compressor 201 releases heat in the second heat exchanger 202. The heating water in the second heating unit 50 absorbs heat in the second heat exchanger 202. The control unit 30 controls the second water pump 502 to transport the high-temperature heating water to the warm air core 501. The high-temperature heating water releases heat in the warm air core 501 to heat the passenger compartment.

[0057] In one embodiment of the present application, the second heating unit 50 further includes an overflow tank 503. The overflow tank 503 is connected in series between the warm air core 501 and the second heat exchanger 202.

[0058] Specifically, the overflow tank 503 can play a role in replenishing liquid and preventing excessive pipeline pressure in the second heating unit 50, ensuring that the heating water can circulate smoothly and realizing the heating of the passenger compartment.

[0059] As Figure 4 shown, the temperature control system further includes a drive motor 70 and a third water pump 60. The third water pump 60, the drive motor 70, and the first heat exchanger 102 are connected in sequence to form a third heating circulation loop. The third water pump 60 is electrically connected to the control unit 30.

[0060] Specifically, when the vehicle is in a driving state, the operation of the drive motor 70 generates heat. The control unit 30 controls the third water pump 60 to transport the heat generated by the drive motor 70 to the first heat exchanger 102, so that the heating water in the first heat exchanger 102 is heated. The control unit 30 controls the first water pump 101 to transport the high-temperature heating water in the first heat exchanger 102 to the battery pack 40 for heat release to heat the battery pack 40.

[0061] As Figure 5 shown, the temperature control method includes steps S501 to S503.

[0062] Step S501, obtaining the operating state of the vehicle; wherein, the operating state of the vehicle includes a charging state and a driving state.

[0063] Specifically, the operating state of the vehicle can be detected by corresponding detectors on the vehicle. For example, a battery detector can detect whether the battery pack 40 is in a discharging state or a charging state, so as to determine whether the vehicle is in a charging state; a motor detector can detect the operating state of the drive motor, so as to determine whether the vehicle is in a driving state.

[0064] Step S502, when the vehicle is in a charging state and receives a heating request sent by the battery pack 40, control the drive motor to send a power consumption request to the battery pack 40, so that the battery pack 40 performs pulse heating.

[0065] Specifically, when the vehicle is in a charging state (i.e., the battery pack 40 is in a charging state), if the temperature of the battery pack 40 is too low, the battery pack 40 will send a heating request to the control unit 30. After receiving the heating request sent by the battery pack 40, the control unit 30 controls the drive motor to send a power consumption request to the battery pack 40. After receiving the power consumption request sent by the drive motor, a pulse current is generated inside the battery pack 40. Due to the large internal resistance of the battery pack 40 in a low-temperature environment, heat will be generated in the battery pack 40 under the action of the pulse current, realizing the heating of the battery pack 40.

[0066] Step S503, when the vehicle is in a driving state and receives a heating request sent by the battery pack 40, control the compressor 201 in the heating unit 20 to generate heat, and control the first water pump 101 in the first heating unit 10 to transfer the heat generated by the compressor 201 to the battery pack 40 to heat the battery pack 40.

[0067] Specifically, when the vehicle is in a driving state (i.e., the battery pack 40 is in a discharging state), if the temperature of the battery pack 40 is too low, the battery pack 40 will send a heating request to the control unit 30. After receiving the heating request sent by the battery pack 40, the control unit 30 controls the compressor 201 and the first water pump 101 to work, and controls the first electronic expansion valve 203 to open. The compressor 201 compresses and does work on the refrigerant, outputting high-temperature refrigerant. The high-temperature refrigerant can enter the first heat exchanger 102 through the first electronic expansion valve 203, or can enter the first heat exchanger 102 through the second heat exchanger 202. The high-temperature refrigerant releases heat in the first heat exchanger 102. The heating water in the first heating unit 10 absorbs heat in the first heat exchanger 102, and the control unit 30 controls the first water pump 101 to transport the heated heating water to the battery pack 40 to heat the battery pack 40.

[0068] The temperature control method provided by the embodiment of the present application does not require a high-power PTC heater when heating the battery pack 40, which can reduce the power consumption of the electric vehicle and help improve the cruising range of the electric vehicle.

[0069] In one embodiment of the present application, the temperature control method further includes step S504.

[0070] Step S504: When a heating request for the passenger compartment is received, control the compressor 201 to generate heat, and control the second water pump 502 in the second heating unit 50 to transfer the heat generated by the compressor 201 to the heater core 501 in the second heating unit 50 to heat the passenger compartment.

[0071] Specifically, when the vehicle is in a charging state or a driving state, the passenger compartment can send a heating request to the control unit 30. When the control unit 30 receives the heating request sent by the passenger compartment, the control unit 30 controls the compressor 201 to generate heat, and the high-temperature refrigerant output by the compressor 201 releases heat in the second heat exchanger 202. The heating water in the second heating unit 50 absorbs heat in the second heat exchanger 202, and the control unit 30 controls the second water pump 502 to transport the high-temperature heating water to the heater core 501. The high-temperature heating water releases heat in the heater core 501 to heat the passenger compartment.

[0072] In one embodiment of the present application, the temperature control method further includes step S505.

[0073] Step S505: When the vehicle is in a driving state and a heating request sent by the battery pack 40 is received, control the third water pump to transfer the heat generated by the drive motor to the first heat exchanger 102 to heat the battery pack 40.

[0074] Specifically, when the vehicle is in a driving state, the drive motor generates heat during operation. The control unit 30 controls the third water pump to transport the heat generated by the drive motor to the first heat exchanger 102 to raise the temperature of the heating water in the first heat exchanger 102. The control unit 30 controls the first water pump 101 to transport the high-temperature heating water in the first heat exchanger 102 to the battery pack 40 for heat release to heat the battery pack 40.

[0075] The present application also provides a vehicle, including the above-described temperature control system. When heating the battery pack, the vehicle does not need to use a high-power PTC heater, which can reduce the power consumption of the electric vehicle and help improve the cruising range of the electric vehicle. For the specific working principle, please refer to the above description of the temperature control system and will not be elaborated here.

[0076] The foregoing embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the protection scope of the present application.
