[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0043] According to one embodiment of the present application, a charging device is provided. Figure 1 As shown, the charging device includes:

[0044] A charging mechanism 17, wherein the charging component is suitable for charging an electrical device; and

[0045] The first heat management mechanism is adapted to supply a heat exchange medium to the electrical equipment to perform heat management on the electrical equipment.

[0046] Specifically, the charging mechanism 17 includes a charger, a charging controller, and a power system that are electrically connected together. The power system is used to supply power to the charger. The charger includes, for example, a branch charging group, an AC charging group, and the like. The charging controller is used to control and monitor the charging process of the charger. The first thermal management mechanism can supply a heat exchange medium to the electrical equipment for heating and cooling the electrical equipment. The heat exchange medium can be, but is not limited to, gas, water, oil, phase change refrigerant, and the like. For example, the charging device also includes a housing 24, and the charging mechanism 17 and the first thermal management mechanism are arranged in the housing 24.

[0047] In this example, the charging device includes a charging mechanism 17, through which the electrical device can be charged. The charging device also includes a first thermal management mechanism. The first thermal management mechanism can supply a heat exchange medium to the electrical device to perform thermal management on the electrical device. In this way, while charging, the electrical device can also be cooled or heated by the heat exchange medium supplied by the charging device, which significantly improves the thermal management efficiency of the electrical device. In addition, the charging device can heat or cool the battery of the electrical device, so that the battery operates within a suitable temperature range, thereby improving the charging efficiency of the battery.

[0048] In one example, the charging device includes a connection component, which is suitable for detachably connecting to an electrical device. The connection component includes a charging connector 501 and an interface module 5. The charging connector 501 is connected to the charging mechanism 17, and the interface module 5 is connected to the first thermal management mechanism.

[0049] like Figure 1 , Figure 4 As shown, the connection component is used to be detachably connected to the external interface 25 of the electric device. Optionally, the connection component is an interface module 5 provided on a charging gun or a charging pile. The connection component realizes the connection between the charging device and the charging circuit and the heat exchange pipeline (for example, the fourth pipeline 22 and the fifth pipeline 23 described below) of the electric device. The charging connector 501 is connected to the charging mechanism 17 through wires, copper bars, etc. The charging connector 501 is used to connect to the charging interface in the external interface 25 of the electric device, thereby realizing the connection between the charging mechanism 17 and the charging circuit of the electric device. The interface module 5 is connected to the first thermal management mechanism through a pipeline. The interface module 5 is used to connect to the heat exchange medium interface in the external interface 25 of the electric device, thereby realizing the connection between the first thermal management mechanism and the heat exchange pipeline of the electric device.

[0050] In one example, the interface module 5 includes a first interface 502 and a second interface 503, any one of the first interface 502 and the second interface 503 is suitable for supplying heat exchange medium to the electrical equipment, and the other of the first interface 502 and the second interface 503 is suitable for recovering the heat exchange medium from the electrical equipment.

[0051] like Figure 4 As shown, the interface module 5 includes a first interface 502 and a second interface 503. One of the first interface 502 and the second interface 503 is an interface for supplying heat exchange medium to the electrical equipment, and the other is an interface for recovering the heat exchange medium flowing through the electrical equipment. For example, the recovered heat exchange medium is supplied to the electrical equipment after heat exchange by the first thermal management mechanism. In this way, the interface module 5 realizes the circulation of the heat exchange medium between the first thermal management mechanism and the electrical equipment.

[0052] Of course, in other examples, the interface module 5 is provided with only one interface, so that the first thermal management mechanism only supplies the heat exchange medium but does not recycle the heat exchange medium.

[0053] In one example, the connection component includes a component housing 51 , and the charging connector 501 and the interface module 5 are located in the component housing 51 .

[0054] like Figure 4 As shown, the component housing 51 is made of metal, plastic, rubber, ceramic, etc. For example, the charging connector 501, the interface module 5, etc. are fixed in the component housing 51 by means of snap-on, injection molding, etc. The component housing 51 integrates the charging connector 501 and the interface module 5 together. The component housing 51 has a connection end, and the charging connector 501 and the interface module 5 are located at the connection end. When connecting, the module housing is connected to the external interface 25 of the electrical device, so that the charging connector 501 and the interface module 5 are connected to the external interface 25 at the same time. This makes it easy to connect the connection component to the external interface 25.

[0055] In one example, the first thermal management mechanism is suitable for performing thermal management on the charging mechanism 17 .

[0056] In this example, the first heat management mechanism is not only used to supply heat exchange medium to the electric device to cool or heat the electric device, but also to cool the charging mechanism 17. This enables the charging mechanism 17 to operate at a suitable temperature, thereby improving the charging efficiency of the charging mechanism 17.

[0057] In one example, the first thermal management mechanism includes a compression device, a condensing device and a first expansion device, the charging device includes a first interface 502 and a second interface 503, any one of the first interface 502 and the second interface 503 is suitable for supplying a heat exchange medium to an electrical device, the other of the first interface 502 and the second interface 503 is suitable for recovering the heat exchange medium from the electrical device, the first interface 502 is connected to the compression device, the condensing device is connected between the compression device and the first expansion device, and the first expansion device is suitable for connecting to the second interface 503.

[0058] like Figure 1 , Figure 4As shown, the compression device includes, for example, a compressor 8. The heat exchange medium is, for example, a phase-change refrigerant. The compressor 8 is used to absorb and compress the phase-change refrigerant from the low-pressure side to increase the temperature and pressure of the phase-change refrigerant, and then pump it into the high-pressure side and circulate it back and forth. The condensing device includes, for example, a condenser 10. The condenser 10 is used to convert the high-temperature and high-pressure phase-change refrigerant into a low-temperature and low-pressure state. The expansion device includes an expansion valve. The expansion valve is used to adjust the flow rate of the phase-change refrigerant so that the phase-change refrigerant fully evaporates and absorbs heat during the evaporation process. The expansion valve includes a first expansion valve 13. The first interface 502 is connected to the compression device through a pipeline, and the second interface 503 is connected to the first expansion valve 13 through a pipeline. The first interface 502 can recover the phase-change refrigerant in a low-pressure state from the electrical equipment. The second interface 503 can supply the phase-change refrigerant to the electrical equipment.

[0059] In one example, the charging device further includes a heat exchange element, wherein the heat exchange element is suitable for performing heat exchange with the charging mechanism 17 , and the heat exchange element is connected to the first heat management mechanism.

[0060] like Figure 1 As shown, the heat exchange element is used for heat exchange. Optionally, the heat exchange element includes a plate heat exchanger 16, a tube heat exchanger, etc. For example, the plate heat exchanger 16 is arranged on a pipeline (such as the first pipeline 26 described below) of the first thermal management mechanism. The plate heat exchanger 16 can transfer the heat of the heat exchange medium to the charging mechanism 17 to cool the charging mechanism 17.

[0061] In one example, the first heat management mechanism includes a first pipeline 26 and a second expansion device, the second expansion device is disposed on the first pipeline 26, and the first pipeline 26 is connected to the heat exchange element.

[0062] like Figure 1 As shown, one end of the first pipeline 26 is connected to the inlet of the compressor 8, and the other end is connected to the outlet of the condenser 10 (or the inlet of the first expansion valve 13). The first pipeline 26 is provided with a plate heat exchanger 16 and a second expansion valve 14. The second expansion valve 14 is connected to the outlet of the condenser 10 through the first pipeline 26. The plate heat exchanger 16 is connected to the inlet of the compressor 8 through the first pipeline 26. The charging mechanism 17 is connected to the circulation pipeline 19. The plate heat exchanger 16 is arranged on the circulation pipeline 19. A water pump 15 is also arranged on the circulation pipeline 19. Water flows in the circulation pipeline 19. The water pump 15 drives the water to circulate in the circulation pipeline 19. The plate heat exchanger 16 transfers the coldness of the phase change refrigerant to the water, and then transfers the coldness to the charging mechanism 17 through the circulation of the water to cool the charging mechanism 17.

[0063] In one example, the charging device further includes a second pipeline 20, one end of the second pipeline 20 is suitable for connection with the first interface 502, and the other end of the second pipeline 20 is suitable for connection between the compression device and the condensation device.

[0064] In this example, if Figure 3 As shown, the second pipeline 20 is connected between the outlet of the compressor 8 and the first interface 502. For example, the compressor 8 receives the phase-changing refrigerant from the first pipeline 26 and supplies it to the second pipeline 20 after compression. The second pipeline 20 can supply the phase-changing refrigerant at the outlet of the compressor 8 to the electrical device through the first outlet.

[0065] In one example, the charging device further includes a first valve and a second valve, wherein the first valve is disposed on the second pipeline 20 , and the second valve is disposed between the first interface 502 and the compression device.

[0066] The valve may be, but is not limited to, a pneumatic valve, a solenoid valve, etc. For example, the first valve is a first solenoid valve 6, and the second valve is a second solenoid valve 7. Figure 2 As shown, when the first interface 502 is used to recover the phase-change refrigerant from the electrical equipment, the second solenoid valve 7 is opened and the first solenoid valve 6 is closed. Figure 3 As described above, when the first interface 502 is used to supply the phase-change refrigerant to the electrical equipment, the first solenoid valve 6 is opened and the second solenoid valve 7 is closed.

[0067] In one example, the charging device further includes a third valve, and the third valve is disposed between the second pipeline 20 and the condenser 10 .

[0068] For example, the third valve is a third solenoid valve 9. Figure 2 As shown, when the phase-change refrigerant at the outlet of the compressor 8 is supplied to the condenser 10, the third solenoid valve 9 is opened and the first solenoid valve 6 is closed. Figure 3 As shown, when the phase-change refrigerant at the outlet of the compressor 8 is supplied to the electrical equipment through the first interface 502, the first solenoid valve 6 is opened and the third solenoid valve 9 is closed.

[0069] In one example, the charging device further includes a third pipeline 21 , one end of the third pipeline 21 is suitable for connecting to the second interface 503 , and the other end of the third pipeline 21 is connected between the condenser 10 and the first expansion device.

[0070] like Figure 3 As shown, the third pipeline 21 is connected between the second interface 503 and the first pipeline 26 , and can supply the phase-change refrigerant from the second interface 503 to the first pipeline 26 without passing through the first expansion valve 13 and the compressor 8 .

[0071] In one example, the charging device further includes a fourth valve and a fifth valve, wherein the fourth valve is disposed on the third pipeline 21 , and the fifth valve is disposed between the third pipeline 21 and the first expansion device.

[0072] The fourth valve is the fourth solenoid valve 11. The fifth valve is the fifth solenoid valve 12. Figure 2 As shown, when the phase-change refrigerant at the outlet of the condenser 10 is supplied to the second interface 503 via the first expansion valve 13, the fifth solenoid valve 12 is opened and the fourth solenoid valve 11 is closed. Figure 3 As shown, when the phase-change refrigerant received by the second interface 503 is supplied to the first pipeline 26 , the fourth solenoid valve 11 is opened and the fifth solenoid valve 12 is closed.

[0073] In one example, the charging device further includes a pump body and a circulation pipeline 19 , the charging mechanism 17 performs heat exchange with the circulation pipeline 19 , and the pump body and the heat exchange element are arranged on the circulation pipeline 19 .

[0074] like Figure 1 As shown, a heat exchange medium, such as water, oil, etc., flows in the circulation pipeline 19. The pump body includes a water pump 15, an oil pump, etc. The pump body is used to circulate the heat exchange medium in the circulation pipeline 19 to transfer the cold energy of the heat exchange element to the charging mechanism 17 to cool the charging mechanism 17.

[0075] In one example, the first thermal management mechanism has a cooling mode. In the cooling mode, the first valve and the fourth valve are closed, the second valve, the third valve and the fifth valve are opened, and the compression device and the pump body are opened; when the electrical equipment is cooled, the heat exchange medium in the first thermal management mechanism passes through the compression device, the third valve, the condensing device, the first expansion device, the fifth valve, the second interface 503, the electrical equipment, the first interface 502 and the compression device in sequence; when the charging mechanism 17 is cooled, the heat exchange medium in the first thermal management mechanism passes through the compression device, the third valve, the condensing device, the second expansion device, the compression device in sequence, and the heat exchange medium in the circulation pipeline 19 passes through the pump body, the charging mechanism 17, the heat exchange element and the pump body in sequence.

[0076] Figure 2A working mode of the charging device is shown. The electrical device is, for example, a vehicle. In this working mode, the charging mechanism 17 is electrically connected to the vehicle's onboard charger 18 to charge the vehicle's battery through the onboard charger 18. The first thermal management mechanism cools the electrical device and the charging mechanism 17. Specifically, the first solenoid valve 6 and the fourth solenoid valve 11 are closed. The second solenoid valve 7, the third solenoid valve 9 and the fifth solenoid valve 12 are opened. The compressor 8 and the water pump 15 are turned on. The first thermal management mechanism cools the battery through the battery direct cooling plate 4 and cools the charging mechanism 17 through the plate heat exchanger 16. For example, the battery cooling process is: the heat exchange medium, such as the phase change refrigerant, passes through the compressor 8, the third solenoid valve 9, the condenser 10, the first expansion valve 13, the fifth solenoid valve 12, and the second interface 503 in sequence to reach the battery direct cooling plate 4, and the phase change refrigerant returns to the first interface 502 after passing through the battery direct cooling plate 4, and then passes through the second solenoid valve 7 to reach the compressor 8, completing a cycle. The refrigeration process of the charging mechanism 17 is as follows: the phase-change refrigerant passes through the compressor 8, the third solenoid valve 9, the condenser 10, and the second expansion valve 14 in sequence to reach the plate heat exchanger 16, and the phase-change refrigerant returns to the compressor 8 after heat exchange in the plate heat exchanger 16. The coldness of the plate heat exchanger 16 is transferred to the water in the circulation pipeline 19, and driven by the water pump 15 to reach the charging mechanism 17, thereby cooling the charging mechanism 17, and the water returns to the plate heat exchanger 16 after heat exchange in the charging mechanism 17.

[0077] In one example, the first thermal management mechanism has a mixed mode. In the mixed mode, the first valve and the fourth valve are opened, the second valve, the third valve and the fifth valve are closed, and the compression device and the pump body are opened; when the electrical equipment is cooled, the heat exchange medium in the first thermal management mechanism passes through the compression device, the first valve, the first interface 502, the heat exchange element, the second interface 503, the fourth valve, the second expansion device, the heat exchange element, and the compression device in sequence, and the heat exchange medium in the circulation pipeline 19 passes through the pump body, the charging mechanism 17, the heat exchange element, and the pump body in sequence.

[0078] Figure 3Another working mode of the charging device is shown. In this working mode, the charging mechanism 17 is electrically connected to the vehicle's onboard charger 18 to charge the vehicle's battery through the onboard charger 18. The first thermal management mechanism cools the charging mechanism 17 and heats the battery. Specifically, the second solenoid valve 7, the third solenoid valve 9 and the fifth solenoid valve 12 are closed. The first solenoid valve 6 and the fourth solenoid valve 11 are opened. The compressor 8 and the water pump 15 are turned on. The phase-change refrigerant does not pass through the condenser 10. The battery heating process includes: the phase-change refrigerant passes through the compressor 8, the first solenoid valve 6, the first interface 502, the battery direct cooling plate 4, the second interface 503, the fourth solenoid valve 11, the second expansion valve 14, the plate heat exchanger 16 and then returns to the compressor 8. When passing through the plate heat exchanger 16, the phase-change refrigerant exchanges heat with the water in the circulation pipeline 19, takes away the heat in the water, and uses the heat for battery heating. Driven by the water pump 15 , the water in the circulation pipeline 19 passes through the charging mechanism 17 , the plate heat exchanger 16 and then returns to the water pump 15 in sequence, thereby cooling the charging mechanism 17 .

[0079] According to another embodiment of the present application, an electrical device is provided, which includes a heat exchange mechanism having an external interface 25, wherein the external interface 25 is adapted to be connected to a first thermal management mechanism of an external device to receive a heat exchange medium of the first thermal management mechanism of the external device.

[0080] In this example, the electrical equipment may be, but is not limited to, vehicles, ships, airplanes, trains, and the like. The electrical equipment includes a battery. Taking a vehicle as an example, the vehicle includes an on-board charger 18. The on-board charger 18 is connected to the battery. The on-board charger 18 is connected to an external interface 25. The external interface 25 is detachably connected to a connecting assembly of the charging device. The heat exchange mechanism includes a battery direct cooling plate 4. The battery direct cooling plate 4 is connected to the external interface 25 via a fourth pipeline 22 and a fifth pipeline 23. For example, the fourth pipeline 22 is suitable for connection to the first interface 502. The fifth pipeline 23 is suitable for connection to the second interface 503. The battery direct cooling plate 4 is used for heat exchange with the battery. While the electrical equipment is connected to the charging device and charges the battery, it can also use the heat exchange medium supplied by the first thermal management mechanism of the charging device to heat and cool the battery, thereby improving the thermal management efficiency of the battery.

[0081] In one example, the electrical equipment further includes a second heat management mechanism 1, and the second heat management mechanism 1 is connected to the heat exchange mechanism.

[0082] like Figure 1As shown, the second thermal management mechanism 1 is, for example, a vehicle air conditioner.
