Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0048] With the increase in the number of new energy vehicles, the requirements for charging facilities are getting higher and higher. The integrated storage and charging machine integrates energy storage and charging functions, which can adjust the power load and increase long-term benefits. At present, the integrated storage and charging machine has been widely used in charging stations for new energy vehicles.

[0049] The integrated storage and charging machine generally refers to the integrated photovoltaic storage and charging machine, where "photovoltaic" refers to photovoltaic power generation, and photovoltaic panels are generally installed on the roof of the charging equipment. "Storage" refers to the intelligent battery device that stores electricity, and "charging" refers to charging new energy vehicles. Therefore, the integrated storage and charging machine can supply power to the grid or vehicles from the battery device when the grid power consumption is at its peak; when the grid power consumption is at its low point, the grid charges the battery device and the vehicle, thus playing the role of peak shaving and valley filling.

[0050] In the related art, the storage and charging integrated machine cools the battery device mainly by cooling the cooling medium through the refrigeration unit (compressor, condenser, etc.) of the thermal management module, and then circulates the cooling medium into the battery device for heat exchange to achieve cooling. However, when the ambient temperature is low, the use of the refrigeration unit to cool the cooling medium leads to high energy consumption.

[0051] Based on the above considerations, in order to solve the problem of high refrigeration energy consumption of the integrated storage and charging machine in the related technology, a storage and charging device is designed. The fan, dry cooler and condenser in the thermal management module are integrated, and the fan and dry cooler are respectively arranged on opposite sides of the condenser. When the ambient temperature is low, the fan can introduce dry cold air, so that the introduced dry cold air can be air-cooled by the dry cooler to achieve cooling of the cooling medium. At the same time, the dry cold air passing through the dry cooler can continue to further exchange heat with the condenser to achieve cooling of the refrigerant medium in the condenser; in this way, the fan can be effectively used to introduce dry cold air for natural cooling, which effectively reduces the refrigeration power of the compressor, and thus can effectively reduce the refrigeration energy consumption.

[0052] The integrated storage and charging device provided in the embodiment of the present application is further described in detail below through the accompanying drawings and specific embodiments.

[0054] The cabinet 100 is used to accommodate other components such as the battery device 200 and the thermal management module 300; optionally, the cabinet 100 includes but is not limited to a rectangular cabinet, a columnar cabinet, a box-type cabinet and other configurations. The cabinet 100, as the external structure of the storage-charging device 1000, can cover and protect the internal battery device 200 and the thermal management module 300 and other components to reduce the impact of rain, dust and the like on the interior of the cabinet 100. In some embodiments, the cabinet 100 can be made of waterproof, dustproof and UV-resistant materials, such as polyvinyl chloride, polycarbonate polypropylene and the like.

[0055] The battery device 200 mentioned in the embodiment of the present application may include one or more battery cell assemblies for providing voltage and capacity. The battery cell assembly may include a plurality of battery cells, and the plurality of battery cells are connected in series, in parallel or in mixed connection through a busbar.

[0056] In some embodiments, a battery cell assembly is generally formed by arranging a plurality of battery cells.

[0057] As an example, the battery cell assembly may be a battery module, which is formed by arranging and fixing a plurality of battery cells to form an independent module. As an example, the battery module may be formed by bundling a plurality of battery cells by a cable tie.

[0058] In some embodiments, the battery device 200 may be a battery pack, which includes a case and one or more battery cell assemblies, wherein the battery cell assemblies are housed in the case.

[0059] As an example, the battery cell assembly may be a battery module, and the battery cell assembly may be accommodated in the box by fixing the battery module in the box.

[0060] As an example, the battery cell assembly may also be housed in the case by directly fixing a plurality of battery cells to the case.

[0061] As an example, the box may include a first box and a second box. The first box and the second box are buckled together to form a closed space inside the box to accommodate the battery cell assembly. The closed here means covered or closed, which can be sealed or unsealed. The first box can be a top cover or a bottom plate.

[0062] As an example, the box body may include a top cover, a frame and a bottom plate. The top cover and the bottom plate are respectively connected to the frame, so that a closed space is formed inside the box body to accommodate the battery cell assembly.

[0063] It should be understood that the box is provided with a heat exchange structure for introducing a cooling medium, and the cooling medium is introduced into the heat exchange structure in a cycle, and the cooling medium is used to achieve heat exchange to achieve a cooling process for the battery device 200. Optionally, the heat exchange structure includes but is not limited to a heat exchange plate, a heat exchange tube, or a heat exchange channel integrated on the wall of the box.

[0064] The thermal management module 300 includes a first circulation loop 301 and a second circulation loop 302. It should be understood that a refrigerant medium (such as Figure 2 The direction of the arrow indicates the flow direction of the refrigerant medium. The cooling medium circulates in the second circulation loop 302. Figure 2 The double arrow in the circuit indicates the flow direction of the cooling medium. The cooling medium is used to exchange heat with the cooling medium to cool the cooling medium; the cooling medium is used to be introduced into the battery device 200 for heat exchange and heat dissipation.

[0065] It should be understood that thermal coupling in this article essentially refers to a direct or indirect connection between two devices, wherein heat is transferred from one device to another; thus, the refrigerant medium flowing in the first circulation loop 301 and the cooling medium flowing in the second circulation loop 302 influence each other through heat conduction.

[0066] The first circulation loop 301 is provided with a condenser 350, and the refrigerant medium can be circulated and cooled by the condenser 350. The second circulation loop 302 is provided with a dry cooler 340 and a battery device 200, and the battery device 200 is circulated and cooled by the cooling medium. The cooling medium can be naturally cooled by the dry cooler 340 and the fan 330; or the cooling medium can be cooled by heat exchange with the refrigerant medium in the first circulation loop 301.

[0067] Among them, the main function of the condenser 350 is to cooperate with the fan to cool the refrigerant medium; the fan 330 is used to guide the air to form an airflow and to form a heat dissipation effect on the dry cooler 340 and the condenser 350; the dry cooler 340 uses the air introduced by the fan 330 to generate convection and heat exchange, and transfers heat from the cooling medium in the dry cooler 340 to the air, so as to realize natural cooling of the cooling medium.

[0068] The fan 330, the dry cooler 340 and the condenser 350 are integrated, that is, the dry cooler 340 is arranged on one side of the condenser 350, the fan 330 is arranged on the other side opposite to the condenser 350, and the air inlet end of the fan 330 faces the condenser 350; in this way, the dry cold air introduced by the air inlet end of the fan 330 can first pass through the dry cooler 340 and naturally cool the cooling medium in the dry cooler 340; the dry cold air absorbs the heat in the dry cooler 340 and heats up to form primary dry hot air, and the primary dry hot air can further perform heat exchange refrigeration treatment on the refrigerant medium of the gas compressed in the condenser 350, and the primary dry hot air absorbs the heat in the condenser 350 and heats up to form secondary dry hot air, which is discharged from the air outlet end of the fan 330.

[0069] At the same time, a ventilation hole 101 is provided on the side wall of the cabinet 100, and the air outlet of the fan 330 is arranged in the ventilation hole 101, so that the secondary dry hot air discharged from the air outlet of the fan 330 can be discharged to the outside of the cabinet 100 through the ventilation hole 101 to reduce the temperature impact in the cabinet 100. Among them, the ventilation hole 101 can be provided at any place of the side wall of the cabinet 100, for example, it is provided on any side of the cabinet 100 along the width direction or any side of the cabinet 100 along the depth direction. Exemplarily, in some embodiments, the ventilation hole 101 is provided on the side wall of one side of the cabinet 100 along the width direction, so that the fan 330, the condenser 350 and the dry cooler 340 are arranged in sequence along the width direction; optionally, an air guide hole can also be provided on the side wall of the cabinet 100 on the other side relative to the ventilation hole 101 in the width direction, so as to introduce dry cold air from the outside and enter the dry cooler 340.

[0070] The integrated storage and charging device 1000 provided in the embodiment of the present application can, when the ambient temperature is low, introduce dry cold air through the fan 330, and use the dry cold air to cool the cooling medium through the dry cooler 340, and at the same time, the dry cold air passing through the dry cooler 340 can continue to further exchange heat with the condenser 350, so as to achieve the cooling of the refrigerant medium in the condenser 350; in this way, the fan 330 can be effectively used to introduce dry cold air for natural cooling, which effectively reduces the required cooling power, and thus can effectively reduce the cooling energy consumption.

[0071] Please refer to Figure 1 and Figure 2In some embodiments, the thermal management module 300 also includes a heat exchanger 320, which includes a first heat exchange part 321 and a second heat exchange part 322 that are thermally coupled, the first heat exchange part 321 is arranged in the first circulation loop 301, and the second heat exchange part 322 is arranged in the second circulation loop 302; a compressor 310 is also arranged in the first circulation loop 301, and the compressor 310, the condenser 350 and the first heat exchange part 321 are arranged in series; the second heat exchange part 322 is connected in parallel with the dry cooler 340.

[0072] The main function of the compressor 310 is to compress the refrigerant medium into a gas, increase its pressure and temperature, and thus provide power for the refrigeration cycle; and, the high-temperature and high-pressure gas discharged from the compressor 310 can be introduced into the condenser 350 to be cooled and condensed into a liquid, so as to achieve the effect of refrigerating the cooling medium.

[0073] The heat exchanger 320 includes a first heat exchange part 321 and a second heat exchange part 322; the first heat exchange part 321 and the second heat exchange part 322 are two flow channel parts coupled inside the heat exchanger 320, respectively. The first heat exchange part 321 is arranged in the first circulation loop 301, so that the refrigerant can flow through the first heat exchange part 321; the second heat exchange part 322 is arranged in the second circulation loop 302, so that the cooling medium can flow through the second heat exchange part 322. Therefore, the refrigerant medium can form heat exchange with the cooling medium in the second heat exchange part 322 in the first heat exchange part 321, and the refrigerant medium can perform cooling operation on the cooling medium. Optionally, the heat exchanger 320 can adopt a plate heat exchanger.

[0074] The compressor 310, the condenser 350 and the first heat exchange part 321 are arranged in series, so that the compressor 310 and the condenser 350 can circulate and refrigerate the refrigerant medium in the first circulation loop 301. Exemplarily, in some embodiments, the first heat exchange part 321 has a first inlet 321a and a first outlet 321b, and the refrigerant medium with a lower temperature formed by compression and refrigeration of the compressor 310 and the condenser 350 can be introduced into the first heat exchange part 321 from the first inlet 321a, and fully heat exchange with the cooling medium in the thermally coupled second heat exchange part 322 in the first heat exchange part 321 and refrigerate the cooling medium, and the heated refrigerant medium can be discharged from the first heat exchange part 321 from the first outlet 321b and circulated into the compressor 310.

[0075] The second heat exchange part 322 is disposed in the second circulation loop 302, so that the cooling medium circulating in the second circulation loop 302 can be introduced into the second heat exchange part 322 and heat exchanged with the cooling medium in the first heat exchange part 321 to reduce the temperature. Exemplarily, in some embodiments, the second heat exchange part 322 has a second inlet 322a and a second outlet 322b, and the cooling medium can be introduced into the second heat exchange part 322 from the second inlet 322a, and fully heat exchanged with the cooling medium in the thermally coupled first heat exchange part 321 in the second heat exchange part 322 to achieve cooling, and the cooling medium with a lower temperature can be exported from the second heat exchange part 322 from the second outlet 322b and used for heat exchange and cooling the battery device 200.

[0076] The second heat exchange part 322 is connected in parallel with the dry cooler 340, and the dry cooler 340 is connected in parallel with the battery device 200; in this way, the second heat exchange part 322, the dry cooler 340 and the battery device 200 are all arranged in parallel in the second circulation loop 302. After the cooling medium flows through the battery device 200 for heat exchange and cools down the battery device 200, the heated cooling medium can be selectively introduced into the dry cooler 340 for natural cooling, or can be selectively introduced into the second heat exchange part 322 and cooled by heat exchange with the refrigerant medium provided by compression refrigeration.

[0077] With such an arrangement, the compressor 310 and the condenser 350 can circulate and cool the refrigerant medium in the first circulation loop 301, and at the same time, the cooling medium in the second circulation loop 302 can be cooled by heat exchange with the refrigerant medium in the first heat exchange part 321 in the second heat exchange part 322, or the cooling medium in the second circulation loop 302 can be naturally cooled in the dry cooler 340. The use of the dry cooler 340 in conjunction with the fan 330 for natural cooling can effectively reduce the refrigeration energy consumption.

[0078] Please refer to Figure 1 and Figure 2 In some embodiments, in the height direction H, the battery device 200 is disposed at the upper part of the cabinet 100 , and the fan 330 , the dry cooler 340 , and the condenser 350 are disposed at the lower part of the cabinet 100 .

[0079] The battery device 200 is arranged in the upper part of the cabinet 100 along the height direction H; it can be understood that the battery device 200 can be arranged in the upper area of ​​the cabinet 100, for example, it can be stacked along the height direction H, or arranged in sequence along the vertical height direction H. The battery device 200 is centrally arranged in the upper area of ​​the cabinet 100, which can facilitate maintenance, wiring assembly operations, etc. of the battery device 200.

[0080] The fan 330, the dry cooler 340 and the condenser 350 are arranged at the lower part of the cabinet 100; it can be understood that the fan 330, the dry cooler 340 and the condenser 350 can be arranged in the lower area of ​​the cabinet 100, that is, the fan 330, the dry cooler 340 and the condenser 350 are placed in a partition with the battery device 200. When the dry cooler 340 and the condenser 350 use dry cold air for heat exchange and heat dissipation, the heat radiation of the battery device 200 has a lower impact on the dry cooler 340 and the condenser 350. In addition, the fan 330, the dry cooler 340 and the condenser 350 are independently arranged in the lower area of ​​the cabinet 100, which is more convenient for maintenance operations.

[0081] In this way, the battery device 200, the fan 330, the dry cooler 340 and the condenser 350 are respectively arranged at the top and bottom of the cabinet 100, which can improve the space utilization rate in the cabinet 100 and facilitate the maintenance and heat dissipation treatment in the cabinet 100.

[0082] Please refer to Figure 1 In some embodiments, there are multiple battery devices 200, and the multiple battery devices 200 are stacked along the height direction H.

[0083] Optionally, the number of the battery devices 200 may be two, three, or any number above three; stacking of the multiple battery devices 200 along the height direction H can effectively improve the compactness of the arrangement of the multiple battery devices 200 .

[0084] In this way, the stacking of multiple battery devices 200 along the height direction H can improve the regularity of the arrangement of the battery devices 200, thereby further improving the space utilization rate in the cabinet 100 and facilitating the overall maintenance of the battery devices 200.

[0085] Please refer to Figure 1 In some embodiments, the integrated storage and charging device 1000 further includes a charging gun assembly 400, which is disposed on the outer wall of the cabinet 100 and is electrically connected to the battery device 200; the charging gun assembly 400 is disposed in the second circulation loop 302, and the charging gun assembly 400 is connected in parallel with the battery device 200.

[0086] The charging gun assembly 400 is used to realize electrical connection with an external electrical device, so that the battery device 200 inside the storage-charging device 1000 can charge the external electrical device. It should be understood that a flow channel structure is also provided inside the charging gun assembly 400 for the flow of cooling medium.

[0087] The charging gun assembly 400 is arranged on the outer wall surface of the cabinet 100; optionally, a snap structure (such as a snap, a snap ring, etc.) can be provided on the outer wall surface of the cabinet 100 to snap-in and position the charging gun assembly 400; or, a receiving groove can be opened on the outer wall surface of the cabinet 100 for the insertion and placement of the charging gun assembly 400.

[0088] The charging gun assembly 400 is disposed in the second circulation loop 302 , so that the cooling medium circulating in the second circulation loop 302 can be introduced into the relevant cooling channel of the charging gun assembly 400 to achieve heat exchange and cooling treatment of the charging gun assembly 400 .

[0089] The charging gun assembly 400 is connected in parallel with the battery device 200, and the battery device 200 is connected in parallel with the dry cooler 340 and the second heat exchange part 322. Therefore, the charging gun assembly 400 is also connected in parallel with the dry cooler 340 and the second heat exchange part 322; thus, the dry cooler 340 can be used to provide cooling medium for the internal circulation of the charging gun assembly 400, and the second heat exchange part 322 can be used to provide cooling medium for the internal circulation of the charging gun assembly 400, so as to provide cooling treatment for the charging gun assembly 400, or the dry cooler 340 and the second heat exchange part 322 can be used simultaneously to provide cooling medium for the internal circulation of the charging gun assembly 400.

[0090] With such configuration, the charging gun assembly 400 can be used to charge the electrical device, and at the same time, the dry cooler 340 and the second heat exchange unit can provide cooling medium to the charging gun assembly 400 to achieve temperature reduction.

[0091] Please refer to Figure 1 In some embodiments, the charging gun assembly 400 and the ventilation hole 101 are respectively located on opposite sides of the cabinet 100 .

[0092] It should be understood that when the fan 330 is working, the fan 330 will take in dry and cold air in the environment and pass through the dry cooler 340 and the condenser 350 in turn to perform heat exchange and dissipation. The dry and cold air will absorb heat and rise in temperature to form dry and hot air with a higher temperature and be discharged from the ventilation hole 101 to the outside of the cabinet 100.

[0093] With such arrangement, when the fan 330 discharges a relatively high temperature airflow to the outside of the cabinet 100 through the ventilation holes 101, the relatively high temperature airflow is far away from the charging gun assembly 400, that is, the hot air discharged from the ventilation holes 101 has less impact on the charging assembly.

[0094] Please refer to Figure 1In some embodiments, the integrated storage and charging device 1000 also includes a battery management system 500, which is electrically connected to the battery device 200 and the charging gun assembly 400; in the height direction H, the battery device 200 is arranged at the top inside the cabinet 100, and the battery management system 500 is located below the battery device 200.

[0095] The battery management system 500 is used to control the charging or discharging of the battery device 200 to achieve energy storage and release. The battery management system 500 is also used to monitor the working state of the battery device 200.

[0096] In this arrangement, the battery management system 500 is accommodated above the cabinet 100 and is arranged below the battery device 200. The arrangement of the battery management system 500 and the battery device 200 is more compact, which can effectively improve the space utilization rate in the cabinet 100; at the same time, the wiring distance between the battery management system 500 and the battery device 200 is shorter, and the line connection assembly operation is more convenient.

[0097] Please refer to Figure 2 and Figure 3 In some embodiments, the dry cooler 340 has an inlet end 341 and an outlet end 342 , wherein the inlet end 341 is disposed at one end of the dry cooler 340 facing the condenser 350 , and the outlet end 342 is disposed at the other end of the dry cooler 340 facing away from the condenser 350 .

[0098] It can be understood that the inlet end 341 of the dry cooler 340 is used to introduce the superheated cooling medium, so that the superheated cooling medium can be cooled in the dry cooler 340 and then discharged from the outlet end 342 of the dry cooler 340 .

[0099] With such arrangement, the dry cold air introduced by the fan 330 first contacts one side of the outlet end 342 of the dry cooler 340, and then the dry cold air fully contacts the coil structure of the dry cooler 340 to achieve sufficient heat exchange with the cooling medium inside the dry cooler 340, and the flow direction of the dry cold air is opposite to the direction of the cooling medium from the inlet end 341 to the outlet end 342 of the dry cooler 340 to form convection, thereby effectively improving the heat exchange and cooling capacity of the dry cold air on the cooling medium.

[0100] Please refer to Figures 1 to 3 In some embodiments, the integrated storage-charging device 1000 further includes a cold storage structure 600 , which is disposed in the second circulation loop 302 , and the cold storage structure 600 is connected in parallel with the battery device 200 .

[0101] The cold storage structure 600 is used to store cooling medium; the cold storage structure 600 can be but is not limited to a container with heat preservation function such as a cold storage tank, a cold storage barrel, a cold storage box, etc.; the cold storage structure 600 can be arranged inside the cabinet 100 or outside the cabinet 100.

[0102] The cold storage structure 600 and the battery device 200 are connected in parallel, and the battery device 200 is connected in parallel with the second heat exchange part 322 and the dry cooler 340. In this way, the cold storage structure 600, the second heat exchange part 322, the dry cooler 340 and the battery device 200 are all arranged in parallel in the second circulation loop 302; the cooling medium derived from the heat exchange refrigeration of the second heat exchange part 322 or the cooling medium derived from the natural cooling refrigeration of the dry cooler 340 can be selectively introduced into the cold storage structure 600 to store cold energy or introduced into the battery device 200 for heat exchange cooling.

[0103] For example, in some embodiments, when the battery device 200 is operated at a high rate, a large amount of heat is generated. At this time, the second heat exchange unit can circulate cooling medium to the battery device 200 to fully perform heat exchange and cooling treatment; in other embodiments, when the battery device 200 is operated at a low rate, less heat is generated. At this time, the second heat exchange unit can introduce cooling medium into the cold storage structure 600 for storage, so that when the battery device 200 generates a large amount of heat in the future, the cold storage device can simultaneously provide cooling medium to reduce the burden on the compressor 310 and the condenser 350; or, when the ambient temperature is low, the dry cooler 340 can be used to cool the cooling medium, and the cooling medium provided by the dry cooler 340 can be introduced and stored in the cold storage structure 600.

[0104] Optionally, in order to improve the fluidity of the cooling medium, a circulation pump can be set in the first circulation loop 301 and the second circulation loop 302 of the thermal management module 300. For example, the circulation pump can be used to connect the cold storage structure 600, and the cooling medium stored in the cold storage structure 600 can be more smoothly discharged through the action of the circulation pump.

[0105] With such arrangement, the cold storage structure 600 can realize the cold storage function, and the cold energy stored in the cold storage structure 600 can be exported when the battery device 200 operates at high power to realize heat exchange and heat dissipation, thereby effectively reducing the energy consumption of compression refrigeration using the compressor 310.

[0106] Please refer to Figure 1 and Figure 2 In some embodiments, the integrated storage and charging device 1000 also includes a first multi-way valve 700 and a second multi-way valve 800, and the multiple valve ports of the first multi-way valve 700 are respectively connected to the outlet end 342, the output end of the second heat exchange part 322 and the cold storage structure 600, and the multiple valve ports of the second multi-way valve 800 are respectively connected to the inlet end 341, the input end of the second heat exchange part 322 and the cold storage structure 600.

[0107] The output end of the second heat exchange part 322 is used to export the cooling medium after refrigeration; it should be understood that the output end of the second heat exchange part 322 is also the second outlet 322b of the second heat exchange part 322 mentioned above. For the convenience of description, the second outlet 322b is used to represent the output end of the second heat exchange part 322. The input end of the second heat exchange part 322 is used to introduce the cooling medium into the second heat exchange part 322, so that the cooling medium can fully exchange heat with the refrigerant medium in the first heat exchange part 321 in the second heat exchange part 322 for refrigeration; it should be understood that the input end of the second heat exchange part 322 is also the second inlet 322a of the second heat exchange part 322 mentioned above. For the convenience of description, the second inlet 322a is used to represent the input end of the second heat exchange part 322 for description.

[0108] The first multi-way valve 700 is a valve device for fluid control. The connection state of different channels in the valve body of the first multi-way valve 700 can be changed by rotation, push-pull or other mechanical operations, that is, the opening and closing states of different valve ports of the first multi-way valve 700 can be controlled, thereby realizing the switching of the fluid flow path.

[0109] Similarly, the second multi-way valve 800 is a valve device for fluid control, which can change the connection status of different channels in the valve body of the second multi-way valve 800 by rotation, push-pull or other mechanical operations, that is, control the opening and closing status of different valve ports of the second multi-way valve 800, thereby realizing the switching of the fluid flow path.

[0110] The multiple valve ports of the first multi-way valve 700 are respectively connected to the outlet end 342, the second outlet 322b and the cold storage structure 600; optionally, in some embodiments, the first multi-way valve 700 can be a three-way valve, so that the three valve ports of the three-way valve can be respectively connected to the outlet end 342, the second outlet 322b and the cold storage structure 600.

[0111] The multiple valve ports of the second multi-way valve 800 are respectively connected to the inlet end 341, the second inlet 322a and the cold storage structure 600; optionally, in some embodiments, the second multi-way valve 800 can be a three-way valve, so that the three valve ports of the three-way valve can be respectively connected to the inlet end 341, the second inlet 322a and the cold storage structure 600.

[0112] It should be understood that the flow direction of the cooling medium can be controlled by controlling the opening and closing of the valve ports of the first multi-way valve 700 and the second multi-way valve 800. Exemplarily, in some embodiments, when the valve port of the first multi-way valve 700 connecting the second outlet 322b and the cold storage structure 600 is opened, the valve port of the first multi-way valve 700 connecting the outlet end 342 is closed, and the valve port of the second multi-way valve 800 connecting the second inlet 322a and the cold storage structure 600 is opened, and the valve port of the second multi-way valve 800 connecting the inlet end 341 is closed, the cooling medium provided by the second heat exchange part 322 can be circulated and introduced into the cold storage structure 600, that is, the cooling medium formed by compression refrigeration can be introduced into the cold storage structure 600 for storage. In other embodiments, when the valve port of the first multi-way valve 700 connecting the outlet end 342 and the cold storage structure 600 is opened, the valve port of the first multi-way valve 700 connecting the second outlet 322b is closed, and the valve port of the second multi-way valve 800 connecting the inlet end 341 and the cold storage structure 600 is opened, and the valve port of the second multi-way valve 800 connecting the second inlet 322a is closed, the cooling medium of the dry cooler 340 after natural cooling by the action of the fan can be circulated and introduced into the cold storage structure 600, that is, the cooling medium formed by natural cooling can be introduced into the cold storage structure 600 for storage.

[0113] Among them, the battery device 200 can be arranged between the first multi-way valve 700 and the second multi-way valve 800; for example, in some embodiments, the first multi-way valve 700 and the second multi-way valve 800 can both be four-way valves, and one of the valve ports of the first multi-way valve 700 and one of the valve ports of the second multi-way valve 800 are respectively connected to the opposite ends of the battery device 200; or, in other embodiments, a third multi-way valve and a fourth multi-way valve (not shown in the figure) can also be included, one end of the battery device 200 is connected between the first multi-way valve 700 and the cold storage structure 600 through the third multi-way valve, and the other end of the battery device 200 is connected between the second multi-way valve 800 and the cold storage structure 600 through the fourth multi-way valve. In this way, through the above two embodiments, it is possible to control the introduction of the cooling medium into the battery device 200 for heat exchange and cooling.

[0114] With such arrangement, the flow direction of the cooling medium can be controlled by using the first multi-way valve 700 and the second multi-way valve 800 to switch the dry cooler 340 , the second heat exchange part and the cold storage structure 600 to perform cooling operation.

[0115] Please refer to Figure 1 In some embodiments, the cold storage structure 600 is placed outside the cabinet 100 , and the cold storage structure 600 is buried under the cabinet 100 .

[0116] Optionally, the cold storage structure 600 may be buried directly below the cabinet 100, that is, in the direction of gravity, the projection of the cold storage structure 600 is within the range of the cabinet 100. Alternatively, the cold storage structure 600 may be buried below the side of the cabinet 100, that is, in the direction of gravity, the projection of the cold storage structure 600 is outside the range of the cabinet 100. Alternatively, in the direction of gravity, the projection of the cold storage structure 600 partially overlaps with the projection of the cabinet 100.

[0117] In some embodiments, a corrosion-resistant layer is provided on the surface of the cold storage structure 600 to reduce the probability of the cold storage structure 600 being corroded and to increase the service life of the cold storage structure 600 .

[0118] It should be understood that when electric vehicles, electric bicycles and other electrical devices are parked around the cabinet 100 for charging, the cold storage structure 600 buried in the ground will not affect the parking of the electrical devices.

[0119] With this arrangement, the heat preservation effect of the cold storage structure 600 buried in the ground is better, and the cold loss of the cooling medium stored in the cold storage structure 600 is smaller; at the same time, when the cold storage structure 600 is buried in the ground, the parking impact on the charging of electrical devices is lower.

[0120] Please refer to Figure 1 In some embodiments, the surface of the cold storage structure 600 is coated with a thermal insulation structure 610 .

[0121] Optionally, the thermal insulation structure 610 includes but is not limited to a layer structure or a cover structure formed by materials with good thermal insulation properties such as foam materials, glass wool, rock wool, etc.; the thermal insulation structure 610 is wrapped on the surface of the cold storage structure 600 to make the thermal insulation effect of the cold storage structure 600 better.

[0122] Optionally, in some embodiments, the cold storage structure 600 may also be made of a stainless steel material to improve the corrosion resistance of the cold storage structure 600 .

[0123] With such a configuration, the heat preservation structure 610 is used to improve the heat preservation effect of the cold storage structure 600 , so as to reduce the cold loss rate of the cooling medium stored in the cold storage structure 600 .
