The battery pack cooling system 60 of the electric vehicle 1000 or the high-voltage electric appliance may include: a liquid storage tank 30, a pump body 40, the pump body 40 is connected to the liquid storage tank 30, and the second cooling circuit 50 is sleeved on the charging harness 12, Further, the second cooling line 50 is also connected to the pump body 40 and the reservoir 30. It can be understood that the difference between this embodiment and the above embodiment is that the second cooling duct 50 no longer passes through the refrigerant, but passes through the cooling water, and is connected to the reservoir 30 and the pump body 40. Thus, when the charging connector 10 is in operation, the pump body 40 starts to operate, and the cooling in the reservoir 30 is pumped into the second cooling line 50, so that the second cooling line 50 can be cooled on the outside of the charging harness 12 to charge the wiring harness. 12, thereby making it possible to better lower the operating temperature of the charging harness 12. It should be noted that the second cooling line 50 can also be used to cool the terminal 11 and/or the housing 14 , that is, the second cooling line 50 can be used for the terminal 11 , the charging line 12 and the housing. At least one of 14. The following description continues with the second cooling duct 50 cooling the charging harness as an example.

After the charging connector 10 is completely charged, the pump body 40 can also pump the cooling in the second cooling line 50 into the liquid storage tank 30, so that the cooling water in the second cooling line 50 can be prevented from leaking, thereby ensuring that the cooling water can be prevented from leaking in the second cooling line 50.

As shown in FIG. 1 and FIG. 6, one end of the charging harness 12 is connected with a power battery 80, and the other end of the charging harness 12 is connected with a charging connector 10, and an inlet of the second cooling duct 50 is disposed near the charging connector 10. One end. The second cooling duct 50 thus disposed can also lower the operating temperature of the charging connector 10 while effectively reducing the temperature of the charging harness 12.

In some embodiments, the outer surface of the charging harness 12 is provided with a waterproof layer. The waterproof layer is arranged to prevent the cooling water from leaking into the interior of the charging harness 12, which ensures the safety of the charging harness 12 and avoids a safety accident.

As shown in FIG. 6, the two ends of the second cooling duct 50 are provided with a sealing sleeve 51, and the sealing sleeve 51 is sleeved on the charging harness 12. Since the second cooling duct 50 is sleeved on the charging harness 12, by providing the sealing sleeve 51 at both ends thereof, it is possible to effectively prevent the coolant from leaking from both ends of the second cooling duct 50, thereby ensuring the second cooling duct. The sealing property of 50 can ensure the safety of use of the charging device 100.

As shown in FIG. 1 and FIG. 6, the battery pack cooling system 60 of the battery of the electric vehicle 1000 or the high-voltage electric appliance may include: a drive motor 62 and a motor controller 61. The drive motor 62 and the motor controller 61 are provided with a connecting line. The connecting line, the pump body 40 and the reservoir 30 are connected in series. That is, the cooling water can flow through the connecting line through the drive motor 62 and the motor controller 61, so that the cooling water can effectively take away the heat at the drive motor 62 and the motor controller 61. In other words, the cooling functions of the drive motor 62, the motor controller 61, and the charging harness 12 are all controlled and provided by the pump body 40 and the reservoir 30, so that the air conditioning cooling system can be effectively simplified.

As shown in FIG. 6, the charging device 100 may further include a cooling fan 90 disposed adjacent to the pump body 40. The cooling fan 90 can effectively enhance the heat exchange capacity of the cooling water with the external environment, so that the charging harness 12, the driving motor 62, and the motor controller 61 can be supplied with low-temperature cooling water.

In some embodiments, the charging device 100 further includes a control valve (not shown) disposed between the pump body 40 and the second cooling line 50. The control valve can be used to shut off the pump body 40 and the second cooling line 50 such that after the second cooling line 50 is filled with the cooling water, the control valve is closed, so that the second cooling line 50 can be kept full and charged. After the end, the control valve is opened to allow the pump body 40 to draw the cooling water in the second cooling line 50. After the pumping is completed, the control valve is closed.

The control valve may be two, and two control valves may be respectively disposed at the inlet and outlet of the second cooling line 50.

In a specific embodiment, the charging device 100 may further include: a controller for detecting the temperature of the charging harness 12, and a temperature sensor electrically connected to the temperature sensor and the control valve to detect the temperature at the temperature sensor. When the value reaches a predetermined value, the pump body 40 is controlled to operate and the control valve is opened. Thus, the control valve and the pump body 40 can be operated synchronously. For example, when the pump body 40 is in operation, the control valve is opened, and when the pump body 40 is stopped, the control valve is closed. This ensures the operational reliability of the air conditioning cooling system.

It can be understood that there are a plurality of temperature sensors, and a plurality of temperature sensors are spaced apart in the longitudinal direction of the charging harness 12. The setting of multiple temperature sensors can help improve the control accuracy of the controller.

In the terminal cooling system 20 in which the compressor 21 is present, the controller may also be electrically connected to the compressor 21 to control the operation of the compressor 21 when the temperature value detected by the temperature sensor reaches a predetermined value. Thereby, the terminal cooling system 20 can be reasonably controlled, so that the operation of the terminal cooling system 20 can be controlled in a timely manner, so that the operating temperature of the charging connector 10 can be ensured.

According to still another alternative embodiment of the present disclosure, as shown in FIG. 7, the air conditioning cooling system includes: a terminal cooling system 20, and the charging device 100 may further include: a cooling compartment 70 on which the charging connector 10 is mounted, That is, the cooling compartment 70 can function to mount the charging connector 10.

The terminal cooling system 20 may include: a compressor 21 connected in series, a condenser 22, a valve body, and an evaporator 23, that is, the compressor 21, the condenser 22, the valve body and the evaporator 23 are connected in series, and the cooling compartment 70 A flow passage is provided on the bulkhead, and the flow passage is configured as at least a portion of the evaporator 23. It will also be appreciated that both the flow path and evaporator 23 are disposed within the cooling compartment 70 and the evaporator 23 is coupled to the cooling compartment 70 by a flow passage. Thereby, the evaporator 23 disposed in the cooling compartment 70 can exchange heat with the charging connector 10 at the cooling compartment 70, and the cooling compartment 70 thus provided can ensure the rationality of the arrangement of the evaporator 23 and the charging connector 10, and The operating temperature of the charging connector 10 can be effectively reduced, and the problem of overheating of the terminal 11 can be avoided.

In some embodiments, as shown in FIGS. 8 and 9, the cooling compartment 70 includes a front mount 71 and a rear mount 72, and an evaporator 23 is disposed between the front mount 71 and the rear mount 72. Under isostatic conditions, the evaporator 23 boils the low-temperature low-pressure refrigerant vapor coming from the capillary 27 to absorb heat and become a dry-saturated vapor of the low-temperature low-pressure refrigerant. The front mount 71 is connected to the rear mount 72, and the front mount 71 and the rear mount 72 are provided with mounting holes for mounting the charging connector 10. Further, the flow path is disposed in the rear mount 72, and the liquid inlet and the liquid outlet of the flow passage penetrate the rear mount 72. That is to say, the charging connector 10 can be mounted on the front fixing seat 71 and the rear fixing seat 72 at the same time, so that the mounting reliability of the charging connector 10 can be ensured on the one hand, and a part of the charging connector 10 can be cooled on the other hand. The interior of the compartment 70, so that the charging connector 10 can be wrapped by the cold air in the cooling compartment 70, can enhance the heat exchange effect of the evaporator 23 and the charging connector 10, thereby further reducing the operating temperature of the charging connector 10.

In some embodiments, the charging device 100 may further include an air cooling passage 73 communicating with the cooling compartment 70, a charging hole provided in the charging connector 10, and the cooling compartment 70 communicating with the ventilation hole. Among them, cold air can flow into the cooling compartment 70 through the air cooling passage 73, and then the cold air flowing into the cooling compartment 70 contacts the charging connector 10 through the vent hole, so that the cooling of the charging connector 10 can be achieved.

In a specific embodiment, as shown in FIGS. 7-9, the terminal cooling system 20 may further include: a blower 25 disposed in the air-cooling passage 73, the outlet of the air-cooling passage 73 and The cooling compartment 70 is in communication. The air blowing member 25 can supply air to the cooling compartment 70. The arrangement of the air supply member 25 can increase the heat exchange efficiency of the evaporator 23 and the charging connector 10, so that the speed of lowering the temperature of the charging connector 10 can be accelerated, and the charging connector 10 can be maintained within a suitable operating temperature range. In some embodiments, the blower 25 can be an axial fan. The axial flow fan can facilitate the air supply to the interior of the cooling compartment 70, and the axial flow fan has a simple structure.

As shown in Fig. 8, the front mount 71 includes a bottom wall 71a and a peripheral wall 71b. The charging connector 10 is fixed to the bottom wall 71a, and the peripheral wall 71b is provided with an air outlet 71c. That is, the cold air blown into the cooling compartment 70 by the air blowing member 25 can be blown out from the air outlet 71c, so that the cold air blown out can be brought into contact with the charging connector 10 again, so that the heat of the charging connector 10 can be better taken away.

As shown in FIG. 10, the charging connector 10 may include a housing 14 and a terminal 11 fixed in the housing 14, and a vent hole 15 is formed in an inner circumference of the housing 14. Therefore, when the charging connector 10 is docked with the charging gun, the cold air enters the cooling compartment 70 through the air inlet 71d, and then the cold air flows out from the air outlet 71c, and then the cold air blown from the air outlet 71c can flow through the air vent 15 to connect the charging. The piece 10 is wrapped so that the cold air can not only cool the charging connector 10, but also cool the charging gun, so that the operating temperature of the charging connector 10 can be better reduced.

In some embodiments, as shown in FIG. 10, the vent holes 15 may be plural, and the plurality of vent holes 15 are circumferentially distributed in the inner circumference of the casing 14. The plurality of vent holes 15 thus arranged can make the housing 14 have a reasonable layout, and can ensure that cold air flows in the circumferential direction of the terminal block 11, so that the heat exchange effect at the charging connector 10 can be improved.

In some embodiments, the charging device 100 may further include: a controller for detecting the temperature of the charging connector 10, a charging sensor for electrically connecting the controller, and a temperature sensor for charging The state detecting module detects that the air blowing member 25 operates when the vehicle 1000 is charging, and is adapted to control the operation of the compressor 21 when the temperature value detected by the temperature sensor is greater than a predetermined value. That is to say, the air blowing member 25 and the compressor 21 can operate at different times. For example, when the temperature is low and the charging connector 10 is just beginning to be charged, the air blowing member 25 starts to operate, and the charging connector 10 can be supplied with a certain flow rate. The normal temperature wind can slow down the operating temperature of the charging connector 10, and when the temperature of the charging connector 10 rises to a predetermined temperature, the compressor 21 starts to work again, and the evaporator 23 first exchanges heat with the air, and the air is recharged. The connector 10 exchanges heat so that the operating temperature of the charging connector 10 can be quickly reduced.

In some embodiments, the charging device 100 may further include: a controller for detecting the temperature of the charging connector 10, a charging sensor for electrically connecting the controller, and a temperature sensor for charging The state detecting module detects that the air blowing member 25 operates when the vehicle 1000 is charging, and is adapted to control the operation of the compressor 21 when the temperature value detected by the temperature sensor is greater than a predetermined value. That is to say, the air blowing member 25 and the compressor 21 can operate at different times. For example, when the temperature is low and the charging connector 10 is just beginning to be charged, the air blowing member 25 starts to operate, and the charging connector 10 can be supplied with a certain flow rate. The cold air can ensure the operating temperature of the charging connector 10, and when the temperature of the charging connector 10 rises to a predetermined temperature, the compressor 21 starts to work again, and the refrigerant in the evaporator 23 and the charging connector 10 exchange heat again. Thereby, the operating temperature of the charging connector 10 can be quickly lowered.
