Description

Technical Field

[0001] This application relates to the field of energy technology, and more particularly to a charging device. Background Technology

[0002] With the acceleration of the dual-carbon goals and the increase in the popularity of electric vehicles, charging stations have increasingly higher requirements for the charging rate of charging equipment. In order to improve the charging rate, it is necessary to continuously increase the power level of charging equipment, and more devices or components need to be installed in the cabinet of the charging equipment.

[0003] In related technologies, multiple components (e.g., switching devices, protection devices, etc.) inside the charging equipment cabinet (e.g., inside the terminal cabinet) are scattered, and the connections between these components are complex (e.g., through connecting copper busbars or connecting cables). These connection structures occupy a significant amount of space inside the charging equipment cabinet, resulting in low space utilization. Furthermore, the scattered distribution of components within the charging equipment cabinet increases the difficulty of assembling and maintaining the charging equipment, leading to increased labor hours for assembly and maintenance. Utility Model Content

[0004] This application provides a charging device that effectively utilizes the internal space of the charging device and facilitates the assembly and maintenance of the charging device.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] This application provides a charging device, which includes a cabinet, a charging connector, a cable, a cooling assembly, and an adapter assembly. The charging connector is located outside the cabinet and is used to connect to the device to be charged. A portion of the cable is located inside the cabinet, and the other portion is located outside the cabinet. The portion of the cable outside the cabinet is connected to the charging connector, and the cable has a cooling channel. The cooling assembly is located inside the cabinet and is used to drive the cooling medium to flow within the cooling channel. The adapter assembly is located inside the cabinet and is distributed vertically with the cooling assembly, or horizontally with the cooling assembly. The adapter assembly includes an input terminal, an output terminal, a switching device, and a protection device. Both the input terminal and the output terminal are connected to the switching device, which is used to control the on / off state of the circuit between the input terminal and the output terminal. The input terminal is used to connect to a power source, the output terminal is connected to the portion of the cable inside the cabinet, and the protection device is connected to either the input terminal or the output terminal.

[0007] Since the input terminals of the adapter are connected to a power source (e.g., the mains), current supplied by the power source is input to the adapter through the input terminals. The switching device of the adapter controls the connection and disconnection of the circuit between the input and output terminals. For example, when the switching device is closed, it allows current to be output from the output terminal. This current is then delivered via a cable to the charging connector, which charges the device to be charged (e.g., an electric vehicle). Furthermore, the adapter's protection device protects the circuit between the input and output terminals.

[0008] In this application, the input terminals, output terminals, switching devices, and protection devices are concentrated on one side of the cooling assembly (e.g., the top, bottom, left, or right side). This facilitates the modular development of the adapter assembly, shortens the length of the adapter busbar or adapter cable, and effectively utilizes the internal space of the cabinet, thereby improving the utilization rate of the cabinet's internal space. Furthermore, since the multiple components included in the adapter assembly are concentrated in one area within the cabinet, it also facilitates the assembly and maintenance of the charging equipment.

[0009] In one embodiment of this application, the input terminal, output terminal, switching device, and protection device are all located above the cooling assembly.

[0010] Placing the cooling assembly below the adapter reduces the likelihood of the cooling medium coming into contact with the adapter in the event of a cooling assembly malfunction leading to leakage (e.g., coolant leak). This reduces the risk of failure in the adapter's components (e.g., switching and protection devices). Furthermore, in some cases where the cooling assembly requires an external cold source via piping, placing it below the adapter reduces the length of that piping. Additionally, in situations where the cooling assembly is heavy, installing it lower within the cabinet (compared to the adapter) reduces safety hazards associated with its installation (as installing it at a higher position might pose safety risks).

[0011] In one embodiment of this application, the inner wall surface of the cabinet includes a bottom surface located below the internal space of the cabinet and a side surface located to the side of the internal space of the cabinet. The switching device is fixed on the side surface, and there is a gap between the switching device and the bottom surface. The input end of the switching device is fixedly connected to the input terminal, and the output end of the switching device is fixedly connected to the output terminal.

[0012] The switching device of the adapter assembly is fixed to the side of the cabinet, and a certain gap is left between the switching device and the bottom of the cabinet, so that the input terminal, output terminal and switching device are suspended in the cabinet. In this way, the space below the switching device can be left for the installation of other devices in the cabinet (such as cooling components, pipelines, etc.), making the layout of the cabinet more reasonable and realizing the effective use of the internal space of the cabinet.

[0013] In one embodiment of this application, the input terminal of the switching device is fixedly connected to the input terminal via a protection device, the protection device being used to disconnect the circuit between the input terminal and the input terminal of the switching device; or, the output terminal of the switching device is fixedly connected to the output terminal via a protection device, the protection device being used to disconnect the circuit between the output terminal and the output terminal of the switching device.

[0014] When the protection device is capable of disconnecting the circuit, for example, if the protection device is a fuse, it can be fixed to the input or output terminal, allowing it to disconnect the circuit between the first and second parts. Furthermore, fixing the protection device to the input or output terminal also allows for greater integration of the adapter assembly, facilitating its overall installation and disassembly.

[0015] In one embodiment of this application, the protection device is a surge protector. The input terminal of the protection device is electrically connected to an input terminal or an output terminal, and the output terminal of the protection device is grounded. The protection device is fixed on the side and has a gap between it and the bottom surface, or the protection device is fixedly connected to a switching device.

[0016] When the protection device is a surge protector, it can shunt current when a spike current or voltage is generated in the circuit. Specifically, if the surge protector is suspended, it can be placed close to the switching device, allowing multiple components of the adapter assembly to be grouped together, which is beneficial for the modular development of the adapter assembly. If the surge protector is fixed to the switching device, the integration of the adapter assembly can be higher, facilitating the overall installation and disassembly of the adapter assembly.

[0017] In one embodiment of this application, the charging device further includes a first cabinet door, which is connected to the cabinet body and can move relative to the cabinet body. The first cabinet door can open or close the internal space of the cabinet body. The side includes a first side and a second side located on both sides of the first cabinet door in the horizontal direction. The adapter also includes a support frame, which is fixed to the first side. The switching device is fixed on the surface of the support frame away from the first side, or the switching device is fixed on the surface of the support frame facing the first cabinet door.

[0018] The switching device is fixed on the side of the support frame away from the first side, or the switching device is fixed on the side of the support frame facing the first cabinet door (the first cabinet door in the closed state). After opening the first cabinet door, the staff can reach into the cabinet to disassemble and install the switching device, which is beneficial for the staff to maintain the switching device and also for the staff to connect or disconnect cables on the switching device.

[0019] Furthermore, the switching devices are fixed to a support frame, which is also fixed to the side of the cabinet. During maintenance of the switching devices inside the cabinet, either the individual switching devices can be disassembled or the entire switching devices and support frame can be disassembled (other components on the support frame will also be disassembled). Moreover, other components of the adapter assembly (such as input terminals, output terminals, and protection devices) can also be fixed to the support frame, resulting in higher integration of the adapter assembly and facilitating its modular development.

[0020] In one embodiment of this application, the cooling assembly includes a first driving member and a first heat exchanger. Both the first driving member and the first heat exchanger are connected to a first side or a second side. The first heat exchanger has a first heat exchange channel that communicates with a cooling channel. The first driving member is used to drive the cooling medium to circulate between the first heat exchange channel and the cooling channel.

[0021] The first driving component drives the cooling medium to flow between the first heat exchange channel and the cooling channel. After entering the cooling channel from the first heat exchange channel, the cooling medium absorbs heat from the cable. The cooled medium, having absorbed heat, flows out of the cooling channel and into the first heat exchange channel of the first heat exchanger. The cooling medium in the first heat exchange channel exchanges heat with air or other cold sources. After heat exchange, the temperature of the cooling medium decreases and it returns to the cooling channel, repeating the cycle to achieve cyclic cooling of the cable. Concentrating the first driving component and the first heat exchanger in one area within the cabinet facilitates the modular development of the cooling components (for example, if needed, the first driving component and the first heat exchanger can be fixed together, increasing the integration of the cooling components), reducing the space occupied by the cooling components within the cabinet.

[0022] Furthermore, if the first drive unit, the first heat exchanger, and the adapter assembly are installed on the same side (first side) inside the cabinet, it also facilitates the connection of pipelines (e.g., pipelines between the first drive unit and the cooling channel, pipelines between the cooling channel and the first heat exchanger, etc.).

[0023] In one embodiment of this application, the cooling assembly further includes a mounting base, and the first drive member and the first heat exchanger are both fixedly connected to the mounting base. The mounting base is slidable relative to the first side or the second side in a direction close to or away from the first cabinet door.

[0024] The first heat exchanger and the first drive component are fixed to the mounting base, resulting in a higher degree of integration of the cooling assembly. When maintenance of the cooling assembly is required, the first heat exchanger or the first drive component can be disassembled and installed individually, or the entire assembly (heat exchanger, drive component, and mounting base) can be disassembled and installed by removing and installing the mounting base. Furthermore, the mounting base slides on the first side. When maintaining the cooling assembly, after opening the first cabinet door, the mounting base can be moved relative to the first side by pulling it out. Then, the mounting base can be gradually pulled out of the cabinet, allowing for inspection or replacement of the first heat exchanger and the first drive component fixed to the mounting base. This facilitates maintenance of the cooling assembly and reduces the time required for maintenance. After maintenance of the cooling assembly is completed, the mounting base is pushed into the cabinet and gradually slid inwards until it is fully reinstalled, thus completing the reinstallation of the cooling assembly.

[0025] In one embodiment of this application, the mounting base is a housing with an internal space. The first drive member and the first heat exchanger are both located inside the mounting base. The mounting base has a medium inlet and a medium outlet that communicate with the first heat exchange channel. Both the medium inlet and the medium outlet are communicated with the cooling channel. The medium inlet and the medium outlet are located on the side wall of the mounting base facing the first cabinet door, or the medium inlet and the medium outlet are located on the side wall of the mounting base away from the first side.

[0026] The mounting base for the cooling assembly is configured as a housing, and the first drive unit and the first heat exchanger are housed within the housing. The housing protects the first drive unit and the first heat exchanger, extending their service life. Furthermore, in the event of a cooling medium leak within the housing, the housing structure reduces the impact of the leaked cooling medium on other devices or circuits within the cabinet.

[0027] Furthermore, both the media inlet and outlet on the mounting base need to be connected to the cooling channel via pipelines. To facilitate the disassembly and maintenance of the pipelines connected to the media inlet and outlet, their positions on the mounting base need to be considered. In this application, the media inlet and outlet are located on the side wall of the mounting base facing the first cabinet door, or on the side wall of the mounting base away from the first side. When maintenance or disassembly of the cooling components is required, the positions of the media inlet and outlet facilitate the disassembly of the pipelines connected to them after opening the first cabinet door. After the cooling components are installed inside the cabinet, the positions of the media inlet and outlet also facilitate the connection of pipelines.

[0028] In one embodiment of this application, the cooling assembly further includes a second driving member connected to the first side or the second side, and the first heat exchanger also has a second heat exchange channel for exchanging heat with the first heat exchange channel, and the second driving member is used to drive the cold source to flow in the second heat exchange channel.

[0029] The second driving component drives the cold source to flow in the second heat exchange channel. The cold source in the second heat exchange channel can exchange heat with the cooling medium in the first heat exchange channel, thereby cooling the cooling medium in the first heat exchange channel and improving the heat exchange efficiency.

[0030] In one embodiment of this application, the charging device further includes a display screen, which is fixed to the cabinet and at least partially exposed outside the cabinet; the charging device further includes a control device, which is located inside the cabinet, and the control device and the cooling component are distributed vertically or horizontally; the control device includes a first controller and a second controller, the first controller being electrically connected to a switching device, and the second controller being electrically connected to the display screen.

[0031] The control device is used to control at least two devices or apparatuses. For example, the control device can control the switching device to disconnect the circuit between the input and output terminals (controlled by the first controller) and can also control the display content of the screen (controlled by the second controller). By controlling multiple devices or apparatuses with one device (control device), in the event of a failure in the control system, only the control device needs to be repaired to quickly resolve the fault, thus facilitating the maintenance of the control system within the cabinet.

[0032] In one embodiment of this application, the charging device further includes a power supply device located inside the cabinet. The power supply device and the cooling component are distributed vertically or horizontally. The power supply device is electrically connected to the first controller, the second controller, and the display screen, and is used to supply power to the first controller, the second controller, and the display screen.

[0033] The power supply unit can supply power to at least two devices or equipment. That is, the power supply unit used to supply power to the transfer components (e.g., switching devices) and the display screen is centrally located in one area of ​​the cabinet, which facilitates the overall disassembly and maintenance of the power supply unit and further improves the modularity of the cabinet.

[0034] In one embodiment of this application, the charging device further includes a second heat exchanger located inside the cabinet. The second heat exchanger has a heat dissipation channel for exchanging heat with the air inside the cabinet.

[0035] During operation, the temperature inside the charging equipment cabinet will rise. When the internal temperature of the cabinet is too high, by providing a cooling medium (such as coolant) to the heat dissipation channel of the second heat exchanger, the heat dissipation channel can exchange heat with the air inside the cabinet, thereby reducing the internal temperature of the cabinet and facilitating the stable operation of the charging equipment.

[0062] In the accompanying drawings of the embodiments of this application, solid structures such as components and assemblies are represented by guide lines; structures composed of multiple components are represented by guide lines with parentheses or solid arrows; and hollow structures such as openings, holes, spaces, and cavities are represented by guide lines with hollow arrows.

[0063] This application provides a charging device 100. Figure 1 An exemplary structure of a charging device 100 is shown, with reference to Figure 1 The charging device 100 is an integrated charging pile. The charging device 100 includes a cabinet 1, a conversion component 2, and a power conversion device 3, both of which are located inside the cabinet 1.

[0064] Reference Figure 1The input terminal of the power conversion device 3 is connected to the power supply 200 (e.g., the power grid) via a wire 201, and the output terminal of the power conversion device 3 is connected to the input terminal of the adapter component 2. The power conversion device 3 is used to convert the current input from the power supply 200 into power and output it to the adapter component 2. For example, the power conversion device 3 includes multiple AC-DC modules, which are used to convert the AC power input from the power grid into DC power and output it to the adapter component 2. In other examples, the power conversion device 3 includes multiple AC-DC modules and multiple DC-DC modules, with the multiple AC-DC modules connected to the multiple DC-DC modules via a DC bus.

[0065] In addition, refer to Figure 1 The charging device 100 also includes a charging connector 4 and a cable 5. The charging connector 4 (e.g., a charging gun) is located outside the cabinet 1. The output end of the charging connector 4 is used to connect to the device 100 to be charged (e.g., an electric vehicle) to charge the device 100. The input end of the charging connector 4 is connected to the output end of the adapter assembly 2 via the cable 5. A portion of the cable 5 is located inside the cabinet 1 for connecting to the adapter assembly 2, and the other portion of the cable 5 is located outside the cabinet 1 for connecting to the charging connector 4. The adapter assembly 2 is used to deliver the DC power output from the power conversion device 3 to the corresponding charging connector 4, and the adapter assembly 2 can control the on / off state of the circuit.

[0066] Figure 2 An exemplary structure of another charging device 100 is shown, with reference to Figure 2 The charging device 100 is a split-type charging pile, comprising a main unit and a terminal unit. The main unit includes a main unit cabinet 101 and a power conversion device 3, which is located inside the main unit cabinet 101. The input terminal of the power conversion device 3 is connected to the power supply 200 via a wire 201, and the output terminal of the power conversion device 3 is connected to the terminal unit via a wire 201.

[0067] Reference Figure 2 The terminal part of the charging device 100 includes a cabinet 1, an adapter 2, a charging connector 4, and a cable 5. The adapter 2 is located inside the cabinet 1. The input end of the adapter 2 is connected to the main unit of the charging device 100 (e.g., to the output end of the power conversion device 3) via a wire 201. The output end of the adapter 2 is connected to the charging connector 4 located outside the cabinet 1 via the cable 5.

[0068] In one example, an adapter component 2 can be connected to a charging connector 4 via a cable 5. In another example, an adapter component 2 can be connected to multiple charging connectors 4 via a cable 5, and this application does not impose any specific limitations on this.

[0069] Figure 3 An exemplary partial structure of a charging device 100 is shown, wherein, Figure 3 The image shows the terminal portion of the charging device 100. Figure 3 Cabinet 1 in the diagram is the terminal cabinet of the terminal section. Figure 4 An exemplary internal structure of a charging device (internal structure of the terminal portion of the charging device 100) is shown, with reference to... Figure 4 The adapter component 2 is installed inside the cabinet 1.

[0070] Among them, reference Figure 4 The adapter component 2 includes an input terminal 21, an output terminal 22, and a switching device 23. The input terminal 21 (e.g., a copper busbar) and the output terminal 22 (e.g., a copper busbar) are both connected to the switching device 23 (e.g., a relay, a circuit breaker, etc.). For example, the input terminal 21 is fixed to the input end of the switching device 23, and the output terminal 22 is fixed to the output end of the switching device 23. The switching device 23 can control the on / off state of the circuit between the input terminal 21 and the output terminal 22.

[0071] Reference Figure 4 The input terminal 21 of the adapter component 2 is electrically connected to the power supply 200 via a wire 201, for example (see auxiliary reference). Figure 2 The power supply 200 is connected to the input terminal of the power conversion device 3 via wire 201, and the output terminal of the power conversion device 3 is connected to the input terminal 21 via wire 201. The output terminal 22 of the adapter component 2 is electrically connected to the charging connector 4 via cable 5. When the switching device 23 is conducting the input terminal 21 and the output terminal 22, the current supplied by the power supply 200 to the input terminal 21 via wire 201 will flow through the switching device 23 and be supplied to the charging connector 4 via the output terminal 22. In the event of a malfunction in the charging device 100, the switching device 23 can also quickly disconnect the circuit between the input terminal 21 and the output terminal 22.

[0072] In addition, refer to Figure 4 The adapter assembly 2 also includes a protection device 24, which can be any device capable of protecting the circuit between the input terminal 21 and the output terminal 22. Figure 4 In the example shown, the protection device 24 can be a fuse. When the current flowing through the protection device 24 increases to a certain level (greater than the current threshold of the protection device 24), the protection device 24 can melt itself and quickly disconnect the circuit (the response speed of the protection device 24 is faster than that of the switching device 23). Referring to... Figure 4The protection device 24 is connected between the output terminal of the switching device 23 and the output terminal 22. That is, the output terminal of the switching device 23 is fixedly connected to the output terminal 22 through the protection device 24. For example, one end of the protection device 24 is fixed to the output terminal 22, and the other end of the protection device 24 is connected to the output terminal of the switching device 23 through a metal busbar. The protection device 24 is used to disconnect the circuit between the output terminal of the switching device 23 and the output terminal 22.

[0073] In some other examples, the protection device 24 is connected between the input terminal of the switching device 23 and the input terminal 21. That is, the input terminal of the switching device 23 is fixedly connected to the input terminal 21 through the protection device 24. For example, one end of the protection device 24 is fixed to the input terminal 21, and the other end of the protection device 24 is connected to the input terminal of the switching device 23 through a metal busbar. The protection device 24 is used to disconnect the circuit between the input terminal of the switching device 23 and the input terminal 21.

[0074] The protection device 24 is fixedly connected to the input terminal 21 or the output terminal 22 (e.g., Figure 4 (This shows the case where the protection device 24 is fixed between the output terminal 22 and the switching device 23), which makes the integration of the adapter assembly 2 higher and facilitates the overall assembly and disassembly of the adapter assembly 2.

[0075] In another example, the protection device 24 may be a surge protector. For example, the input terminal of the protection device 24 may be electrically connected to the input terminal 21 via a wire, or the input terminal of the protection device 24 may be electrically connected to the output terminal 22 via a wire. In addition, the output terminal of the protection device 24 may be grounded. In the event of a surge current or voltage in the circuit, the protection device 24 shunts the current flowing through the input terminal 21 or the current flowing through the output terminal 22, thereby reducing the risk of surge damage to other devices in the power loop.

[0076] In the case where the protection device 24 is a surge protector, it can be fixedly connected to the switching device 23. For example, the protection device 24 and the switching device 23 can be fixed together by bolts; or, for example, they can be snapped together. After the protection device 24 and the switching device 23 are removed from the cabinet 1, they can still remain relatively stationary, resulting in a higher degree of integration of the adapter assembly 2 and facilitating the overall disassembly and assembly of the adapter assembly 2.

[0077] When the protective device 24 is a surge protector, it can also be installed separately from the switching device 23. That is, the protective device 24 is not directly fixed to the switching device 23; for example, the protective device 24 and the switching device 23 are not fixedly connected by bolts or other fastening structures. In this example, the protective device 24 and the switching device 23 are each fixed to a structure, and they are only electrically connected by wires. For example, both the protective device 24 and the switching device 23 are fixed to the cabinet 1, and there is a gap between them.

[0078] Figure 5 An exemplary structure of a cable 5 is shown, wherein the cable 5 has a cooling channel 51, which can be any channel located within the cable 5 that allows the flow of a cooling medium (e.g., water-based cooling medium, oil-based cooling medium, etc.). For example, the cable 5 includes an outer sheath, a wire, and a cooling tube. One end of the wire is electrically connected to a charging connector 4, and the other end of the wire is electrically connected to the output terminal 22 of the adapter assembly 2. Both the wire and the cooling tube are encased within the outer sheath, and the cooling channel 51 is formed within the cooling tube. As another example, the wire is located within the cooling tube, and the cooling channel 51 is formed within the cooling tube; that is, the wire is located within the cooling channel 51, and the outer sheath is wrapped around the cooling tube.

[0079] To facilitate the flow of the cooling medium within the cooling channel 51, refer to... Figure 4 and Figure 5 The charging device 100 also includes a cooling component 6, which is located inside the cabinet 1 and is used to drive the cooling medium to flow in the cooling channel 51 of the cable 5.

[0080] The cooling component 6 can be any device capable of driving the cooling medium to flow within the cooling channel 51. In one example, Figure 6 An exemplary structure of a cooling component 6 is shown, with reference to Figure 6 The cooling assembly 6 includes a first drive element 61 and a first heat exchanger 62. The first heat exchanger 62 (e.g., an air-cooled heat exchanger) has a first heat exchange channel 621, which communicates with the cooling channel 51. The first drive element 61 (e.g., a liquid pump) drives the cooling medium to circulate between the first heat exchange channel 621 and the cooling channel 51. After entering the cooling channel 51 from the first heat exchange channel 621, the cooling medium absorbs heat from the cable 5. After absorbing heat, the cooling medium flows out of the cooling channel 51 and enters the first heat exchanger 62. The cooling medium exchanges heat with the air in the first heat exchanger 62, thus cooling the cooling medium. After exchanging heat in the first heat exchanger 62, the cooling medium re-enters the cooling channel 51, and the cycle repeats to cool the cable 5.

[0081] In another example, Figure 7An exemplary diagram shows the structure of another cooling component 6, with reference to Figure 7 The cooling assembly 6 includes a first drive member 61, a first heat exchanger 62, a second drive member 63, and a cold source storage tank 64 (e.g., a water tank). The first heat exchanger 62 (e.g., a liquid-cooled heat exchanger) has a first heat exchange channel 621 and a second heat exchange channel 622. The first heat exchange channel 621 communicates with a cooling channel 51. The first drive member 61 drives the cooling medium to circulate between the first heat exchange channel 621 and the cooling channel 51. The second heat exchange channel 622 communicates with the cold source storage tank 64. The second drive member 63 drives the cold source (e.g., water) to circulate between the cold source storage tank 64 and the second heat exchange channel 622. Within the first heat exchanger 62, the first heat exchange channel 621 exchanges heat with the second heat exchange channel 622, thereby cooling the cooling medium in the first heat exchange channel 621 and improving the heat exchange efficiency of the first heat exchanger 62.

[0082] In another example, the first heat exchanger 62 is a liquid-cooled heat exchanger, having a first heat exchange channel 621 and a second heat exchange channel 622. However, the second drive unit 63 and the cold source storage tank 64 are both located outside the cabinet 1. That is, in this example, the cooling assembly 6 includes the first drive unit 61 and the first heat exchanger 62, but does not include the second drive unit 63 and the cold source storage tank 64, which are otherwise located outside the cabinet 1.

[0083] Figure 8 An exemplary diagram showing the positional relationship between the adapter assembly and the cooling assembly is provided, with reference to... Figure 8 The multiple components included in the transition assembly 2 (e.g., switching device 23, protection device 24, etc.) are concentrated in one area of ​​the cabinet 1, while the multiple devices included in the cooling assembly 6 (e.g., first drive unit 61, first heat exchanger 62, etc.) are concentrated in another area of ​​the cabinet 1. That is, the transition assembly 2 and the cooling assembly 6 are each located in their own dedicated areas. For example, the transition assembly 2 and the cooling assembly 6 are distributed vertically (in the direction of gravity). Figure 8 This situation is illustrated in the figure; for example, the adapter assembly 2 and the cooling assembly 6 are distributed in the horizontal direction (perpendicular to the direction of gravity).

[0084] The adapter component 2 is positioned horizontally or vertically on one side of the cooling component 6 (e.g., top, bottom, left, right, front, or rear), allowing both the adapter component 2 and the cooling component 6 to occupy their respective designated areas. This facilitates the modular development of the charging device 100, shortens the length of the adapter copper busbar or adapter cable, reduces the space occupied by the adapter component 2 and the cooling component 6 within the cabinet 1, and effectively utilizes the internal space of the cabinet 1. Furthermore, the modular design of the adapter component 2 and the cooling component 6 also simplifies manufacturing, reduces assembly time, and increases production capacity.

[0085] Reference Figure 8 The adapter assembly 2 and the cooling assembly 6 are distributed vertically. The adapter assembly 2 (including input terminal 21, output terminal 22, switching device 23, and protection device 24, etc.) is located above the cooling assembly 6 (including first drive unit 61, first heat exchanger 62, etc.). In the event of a leak in the cooling assembly 6 (e.g., cooling medium leakage), the likelihood of the cooling medium coming into contact with the components in the adapter assembly 2 (e.g., switching device 23, protection device 24, etc.) is reduced, thus lowering the risk of adapter assembly 2 malfunction. Furthermore, in some cases, the cold source storage box 64 is located outside the cabinet 1, and the cooling assembly 6 needs to be connected to the cold source storage box 64 via piping. Placing the cooling assembly 6 below the adapter assembly 2 can also reduce the length of the piping connecting to the cold source storage box 64. In addition, the cooling assembly 6 is relatively heavy. Placing the cooling assembly 6 in a relatively low position can also reduce the safety hazards caused by installing the cooling assembly 6 (e.g., the cooling assembly 6 falling).

[0086] In some other examples, the adapter assembly 2 (including input terminal 21, output terminal 22, switching device 23 and protection device 24, etc.) may also be located below the cooling assembly 6 (including first drive 61, first heat exchanger 62, etc.).

[0087] In some other examples, the adapter 2 and the cooling assembly 6 are distributed in a horizontal direction, wherein the horizontal direction includes a first horizontal direction and a second horizontal direction that are perpendicular to each other. For example, the first horizontal direction may be the width direction of the cabinet 1 and the second horizontal direction may be the thickness direction of the cabinet 1. Figure 9 An exemplary diagram illustrates another positional relationship between the adapter assembly 2 and the cooling assembly 6, with reference to... Figure 9 The adapter 2 and the cooling assembly 6 are distributed along the first horizontal direction (the width direction of the cabinet 1). Figure 10 An exemplary view shows another positional relationship between the adapter assembly 2 and the cooling assembly 6, with reference to Figure 10 The adapter 2 and the cooling assemblies 6 are distributed along the second horizontal direction (the thickness direction of the cabinet 1).

[0088] In this application, "vertical direction" and "horizontal direction" are not absolute terms and are allowed to have some degree of error. As long as the adapter component 2 and the cooling component 6 overlap in the horizontal direction (including the first and second horizontal directions), it is considered that the adapter component 2 and the cooling component 6 are distributed along the "horizontal direction." For example, Figure 11 An exemplary view shows another positional relationship between the adapter assembly 2 and the cooling assembly 6, wherein, with reference to Figure 11 The adapter assembly 2 and the cooling assembly 6 overlap in the horizontal direction, therefore, in Figure 11 In the example shown, the adapter assembly 2 and the cooling assembly 6 are distributed horizontally. If the adapter assembly 2 and the cooling assembly 6 do not overlap horizontally, they are considered to be distributed vertically. Figure 12 An exemplary view shows another positional relationship between the adapter assembly 2 and the cooling assembly 6, wherein, with reference to Figure 12 The adapter assembly 2 and the cooling assembly 6 do not overlap in the horizontal direction, therefore, in Figure 12 In the example shown, the adapter component 2 and the cooling component 6 are distributed along the vertical direction.

[0089] Return to reference Figure 8 The inner wall of the cabinet 1 includes a side surface 11 located on the side of the inner space of the cabinet 1, a top surface 12 located above the inner space of the cabinet 1, and a bottom surface 13 located below the inner space of the cabinet 1. The side surface 11 is located between the top surface 12 and the bottom surface 13, and the side surface 11 surrounds the top surface 12 and also surrounds the bottom surface 13.

[0090] In one example, refer to Figure 8 The switching device 23 is fixed on the side 11, and both the input terminal 21 and the output terminal 22 are fixed on the switching device 23. A certain gap is left between the switching device 23 and the bottom surface 13. That is, a certain distance is left between the switching device 23, the input terminal 21, and the output terminal 22 and the bottom surface 13, meaning the adapter assembly 2 is suspended inside the cabinet 1. The gap between the adapter assembly 2 and the bottom surface 13 allows for the installation of other devices (e.g., cooling assembly 6, piping, etc.), making the internal layout of the cabinet 1 more rational.

[0091] In the example where the switching device 23 is suspended on the side 11, the protective device 24 can be fixed to the switching device 23, resulting in higher integration of the adapter assembly 2 and facilitating its overall assembly and disassembly. Alternatively, the protective device 24 can be suspended on the side 11 of the cabinet 1, meaning there is a certain gap between the protective device 24 and the bottom surface 13 of the cabinet 1, allowing it to be close to the switching device 23. This centralized arrangement of multiple devices in the adapter assembly 2 promotes its modular development.

[0092] In one example, the cabinet 1 has a first opening 14 that communicates with its internal space (for example, the first opening 14 may be an access panel for the cabinet 1). Figure 13 An exemplary diagram shows the structure of the first opening 14, with reference to Figure 13 The charging device 100 also includes a first cabinet door 141, which is connected to the cabinet body 1 and movable relative to the cabinet body 1. For example, the first cabinet door 141 is rotatably connected to the cabinet body 1 via a hinge shaft, in which case the first cabinet door 141 can rotate relative to the cabinet body 1. The first cabinet door 141 is used to open or close the first opening 14, that is, the first cabinet door 141 can open or close the interior space of the cabinet body 1. In addition, the side 11 of the cabinet body 1 includes a first side 111 and a second side 112 located on both sides of the first opening 14 in the horizontal direction (e.g., the first horizontal direction), wherein the first side 111 and the second side 112 are also located on both sides of the first cabinet door 141 (the first cabinet door 141 in the closed state) in the horizontal direction (e.g., the first horizontal direction). The adapter assembly 2 can be installed on the first side 111, and the adapter assembly 2 can also be installed on the second side 112.

[0093] In the case of multiple adapter components 2, all of the adapter components 2 can be installed on the first side 111 (or the second side 112), or, a portion of the multiple adapter components 2 can be installed on the first side 111 and another portion can be installed on the second side 112.

[0094] Figure 14 An exemplary structure of an adapter component 2 is shown, with reference to... Figure 14 The adapter assembly 2 also includes a support frame 25, which can be any structure that can provide support or connection. The support frame 25 is fixed to the first side 111 (or the second side 112). Switching devices 23, protection devices 24 and other devices are fixed on the surface of the support frame 25 away from the first side 111, which makes it convenient for workers to disassemble, install and repair the switching devices 23, protection devices 24 and other devices through the first opening 14. It also makes it convenient for workers to disassemble or connect the cables 5 on the adapter assembly 2 through the first opening 14.

[0095] In some other examples, Figure 15 An exemplary embodiment shows the structure of another adapter component 2, with reference to Figure 15 The switching device 23, the protection device 24 and other devices are fixed on the surface of the support frame 25 facing the first opening 14. In this example, it is also convenient for the staff to disassemble, install and repair the switching device 23, the protection device 24 and other devices through the first opening 14.

[0096] Return to reference Figure 13 The cooling assembly 6 may also include a mounting base 65, in Figure 13 In the example shown, the mounting base 65 is a housing with internal space, and structures such as the first heat exchanger 62 and the first drive unit 61 are all located within the mounting base 65, resulting in a higher degree of integration of the cooling assembly 6. Furthermore, by making the mounting base 65 a housing, in the event of leakage at the connections between the various devices (first heat exchanger 62, first drive unit 61, etc.) inside the mounting base 65, the housing structure of the mounting base 65 can reduce the possibility of leaked liquid (e.g., cooling medium) flowing into the cabinet 1. In addition, the mounting base 65 also protects the first drive unit 61 and the first heat exchanger 62, extending their service life.

[0097] In other examples, the mounting base 65 can be a support platform on which structures such as the first heat exchanger 62 and the first drive component 61 are fixed, and the mounting base 65 provides support for these structures. Furthermore, in this example, fixing the first heat exchanger 62 and the first drive component 61 to the mounting base 65 also improves the integration of the cooling assembly 6.

[0098] The mounting base 65 can be connected to the side 11 (first side 111 or second side 112) of the cabinet 1 in any suitable manner. For example, the mounting base 65 can be fixed to the side 11 of the cabinet 1; or, for another example, the mounting base 65 can be slidably connected to the side 11 of the cabinet 1.

[0099] With the mounting base 65 slidably connected to the side 11 of the cabinet 1 (the mounting base 65 is slidably connected to the first side 111 or the second side 112), the mounting base 65 can slide relative to the cabinet 1. The sliding direction of the mounting base 65 is towards or away from the first opening 14 (the thickness direction of the cabinet 1, or the second horizontal direction). That is, the mounting base 65 can slide towards or away from the first cabinet door 141 (the first cabinet door 141 in the closed state). During the maintenance of the cooling assembly 6, first open the first cabinet door 141. The mounting base 65 can be slid towards the first opening 14 by pulling or other means. Then, gradually pull the mounting base 65 out of the cabinet 1 from the first opening 14 (or at least pull the mounting base 65 closer to the first opening 14), and then perform maintenance on the cooling assembly 6. After the maintenance of the cooling component 6 is completed, push the mounting base 65 into the cabinet 1 and gradually slide the mounting base 65 away from the first opening 14 into the cabinet 1 until it is installed and reset, thus completing the reinstallation of the cooling component 6.

[0100] The mounting base 65 is connected to the cabinet 1 in a sliding manner, which facilitates the maintenance of the cooling component 6. The sliding connection between the mounting base 65 and the side 11 includes, but is not limited to, connection methods that allow the mounting base 65 and the side 11 to slide relative to each other, such as through grooves, slide rails, or plug-in connections.

[0101] In some examples, where the mounting base 65 is slidably connected to the side 11 of the cabinet 1, the mounting base 65 can also be detached from the side 11. In other examples, the mounting base 65 cannot slide relative to the cabinet 1. In such examples, the mounting base 65 can be fixedly connected to the side 11 of the cabinet 1 by removable fasteners (e.g., bolts, screws, etc.) to allow for the mounting base 65 to be attached and detached.

[0102] exist Figure 13 In the example shown, the mounting base 65 and the adapter assembly 2 are both fixed on the first side 111. That is, the first drive unit 61, the first heat exchanger 62, and the adapter assembly 2 are installed on the same side (first side 111) inside the cabinet 1, which facilitates the connection of pipelines, for example, facilitating the connection of pipelines between the first drive unit 61 and the cooling channel 51 (cooling channel 51 auxiliary reference). Figure 6 or Figure 7 ).

[0103] In some other examples, the mounting base 65 and the adapter assembly 2 are fixed to the first side 111 and the other to the second side 112.

[0104] Reference Figure 13 When the mounting base 65 is a housing, the mounting base 65 has a medium inlet 651 and a medium outlet 652 communicating with the first heat exchange channel 621 (the first heat exchange channel 621 is an auxiliary reference). Figure 6 or Figure 7 Both the medium inlet 651 and the medium outlet 652 are connected to the cooling channel 51 of the cable 5 via pipes (cooling channel 51 auxiliary reference). Figure 6 or Figure 7 Driven by the first driving member 61, the cooling medium flows from the first heat exchange channel 621 to the medium outlet 652, and from the medium outlet 652 through the pipeline to the cooling channel 51. After absorbing the heat of the cable 5 in the cooling channel 51 of the cable 5, the cooling medium flows through the pipeline to the medium inlet 651, and finally flows into the first heat exchange channel 621 of the first heat exchanger 62.

[0105] In the case where cabinet 1 includes the first opening 14, refer to Figure 13The medium inlet 651 and medium outlet 652 are located on the side wall of the mounting base 65 facing the first opening 14. That is, the medium inlet 651 and medium outlet 652 are located on the side wall of the mounting base 65 facing the first cabinet door 141 (the first cabinet door 141 in the closed state). After opening the first cabinet door 141, the operator can quickly disassemble and maintain the pipes connected to the medium inlet 651 and medium outlet 652 while facing the first opening 14. For example, when the operator needs to disassemble or replace the cooling component 6, the disassembly of the pipes connected to the medium inlet 651 and medium outlet 652 can be completed at the first opening 14.

[0106] In some other examples, Figure 16 An exemplary embodiment shows the structure of another cooling component 6, with reference to Figure 16 The medium inlet 651 and the medium outlet 652 are located on the side wall of the mounting base 65 away from the first side 111. This design also makes it easier for workers to maintain the pipelines connected to the medium inlet 651 and the medium outlet 652 from the first opening 14.

[0107] In some other examples, in order to shorten the distance between the media inlet 651 and the media outlet 652 and the cable 5, the media inlet 651 and the media outlet 652 may be located on the side wall of the mounting base 65 facing the adapter assembly 2.

[0108] Furthermore, to facilitate inspection or maintenance operations by personnel using their right hand (which is the dominant hand and easier to operate), both the cooling assembly 6 and the adapter assembly 2 can be installed on the first side 111, and the first side 111 is located on the left side of the interior space of the cabinet 1 (the left side when the personnel are standing outside the cabinet 1 and facing the first opening 14). For example, in Figure 16 From the perspective of [the viewpoint], the first side 111 is located on the left side of the interior space of cabinet 1.

[0109] In some other examples, the cabinet 1 may have more than one opening 14 for maintenance. For example, the cabinet 1 may also have a second opening 15 that communicates with its internal space (for example, the second opening 15 may be another access port of the cabinet 1). Figure 17 An exemplary structure of the second opening 15 is shown, with reference to Figure 17The second opening 15 and the first opening 14 are disposed opposite each other in the thickness direction (second horizontal direction) of the cabinet 1. The charging device 100 also includes a second cabinet door 151, wherein the second cabinet door 151 is connected to the cabinet 1 and is movable relative to the cabinet 1. For example, the second cabinet door 151 is rotatably connected to the cabinet 1 via a hinge shaft. In this case, the second cabinet door 151 is able to rotate relative to the cabinet 1. The second cabinet door 151 is used to open or close the second opening 15, that is, the second cabinet door 151 can open or close the internal space of the cabinet 1.

[0110] In one example, where the cabinet 1 has a first opening 14 and a second opening 15, multiple adapter assemblies 2 and multiple cooling assemblies 6 can be installed inside the cabinet 1. For example, refer to... Figure 17 There are two adapter components 2 and two cooling components 6. One adapter component 2 and one cooling component 6 are located on the first side 111 of the cabinet 1, and the other adapter component 2 and the other cooling component 6 are located on the second side 112 of the cabinet 1. The two adapter components 2 and the two cooling components 6 are distributed along the first horizontal direction.

[0111] Among them, reference Figure 17 The adapter assembly 2, mounted on the first side 111, has its switching device 23 positioned away from the first side 111 (e.g., it can be connected via a support frame 25), facilitating maintenance of the adapter assembly 2 by personnel through the first opening 14. The cooling assembly 6, mounted on the first side 111, has its mounting base 65 sliding towards or away from the first opening 14. Furthermore, a medium inlet 651 and a medium outlet 652 are located on the side wall of the mounting base 65 facing the first opening 14, allowing personnel to easily maintain the cooling assembly 6 through the first opening 14 after the first cabinet door 141 is opened.

[0112] Figure 18 An example is shown Figure 17 The structure of cabinet 1 from the other side, see reference. Figure 18 The adapter assembly 2, mounted on the second side 112, has its switching device 23 positioned away from the second side 112 (e.g., it can be connected via a support bracket 25), facilitating maintenance of the adapter assembly 2 by personnel through the second opening 15. The cooling assembly 6, mounted on the second side 112, has its mounting base 65 sliding towards or away from the second opening 15. Furthermore, a medium inlet 651 and a medium outlet 652 are located on the side wall of the mounting base 65 facing the second opening 15, allowing personnel to easily maintain the cooling assembly 6 through the second opening 15 after the second cabinet door 151 is opened.

[0113] exist Figure 17 and Figure 18In the example shown, after opening the first cabinet door 141, with the worker facing the first opening 14, the first side 111 is located on the left side of the interior space of the cabinet 1. After opening the first cabinet door 141, the worker can use their right hand to disassemble or repair the adapter component 2 and cooling component 6 located on the first side 111, facilitating maintenance of these components. When the worker is facing the second opening 15, the second side 112 is located on the left side of the interior space of the cabinet 1. After opening the second cabinet door 151, the worker can also use their right hand to disassemble or repair the adapter component 2 and cooling component 6 on the second side 112.

[0114] In some other examples, where cabinet 1 has a first opening 14 and a second opening 15, cabinet 1 may also contain only a transition assembly 2 and a cooling assembly 6.

[0115] In some other examples, the cabinet 1 is provided with multiple transition components 2 and multiple cooling components 6, but the cabinet 1 has only one maintenance port. For example, the cabinet 1 is provided with only a first opening 14 and not a second opening 15.

[0116] Furthermore, since some components inside the cabinet 1 generate heat during use, causing the internal temperature of the cabinet 1 to rise, and excessively high temperatures inside the cabinet 1 pose certain risks (such as accelerated component aging, short circuits, etc.), in some examples, the charging device 100 may also include a second heat exchanger 8. Figure 19 An exemplary structure of a second heat exchanger 8 is shown. The second heat exchanger 8 is located inside the cabinet 1 and has a heat dissipation channel 81 for exchanging heat with the internal air of the cabinet 1.

[0117] When the temperature inside the cabinet is too high, a cooling medium (e.g., coolant) is introduced into the heat dissipation channel 81 of the second heat exchanger 8. The cooling medium exchanges heat with the air inside the cabinet 1 in the heat dissipation channel 81, thereby reducing the internal temperature of the cabinet 1. In an example where the cooling assembly 6 includes a cold source storage tank 64, a cooling medium can be provided to the heat dissipation channel 81 of the second heat exchanger 8 through the cold source storage tank 64 (in this example, the cooling medium is the cold source inside the cold source storage tank 64).

[0118] In other examples, a cooling medium can also be provided to the heat dissipation channel 81 of the second heat exchanger 8 through other external devices, and this application does not impose any specific limitations on this.

[0119] The second heat exchanger 8 can be any device with a heat dissipation channel 81 and capable of exchanging heat with the air inside the cabinet 1, such as a plate heat exchanger, a tube heat exchanger, etc.

[0120] exist Figure 19 In the example shown, the charging device 100 has two transition assemblies 2 and two cooling assemblies 6 inside its cabinet 1. The two transition assemblies 2 are distributed along a first horizontal direction, and the two cooling assemblies 6 are distributed along a first horizontal direction. A second heat exchanger 8 is located between the two cooling assemblies 6. In some other examples, the second heat exchanger 8 is located between the two transition assemblies 2.

[0121] In an example where a transition assembly 2 and a cooling assembly 6 are located inside the cabinet 1, the second heat exchanger 8 is located to the side of the transition assembly 2, or the second heat exchanger 8 is located to the side of the cooling assembly 6.

[0122] In some examples, the charging device 100 also includes a display screen 7, which is used to display charging-related parameters such as current, charging power, and charging time during the charging process. The display screen 7 is fixed to the cabinet 1 and is at least partially exposed outside the cabinet 1, and the part of the display screen 7 exposed outside the cabinet 1 can be observed by personnel.

[0123] Among them, reference Figure 19 The charging device 100 may further include a control device 9, located inside the cabinet 1. The control device 9 includes a first controller 91 and a second controller 92. The first controller 91 is electrically connected to a switching device 23 and can control the switching device 23 to disconnect the circuit between the input terminal 21 and the output terminal 22. The second controller 92 is electrically connected to a display screen 7 and can control the display content of the display screen 7. In other words, the control device 9 can both control the switching device 23 to disconnect the circuit between the input terminal 21 and the output terminal 22 (via the first controller 91) and control the display content of the display screen 7 (via the second controller 92).

[0124] In one example, both the first controller 91 and the second controller 92 are control boards (including circuit boards and control chips). That is, the control device 9 may include multiple control boards (circuit boards), which are centrally located in one area within the cabinet 1. One control board (the first controller 91) can control the switching device 23, and the other control board (the second controller 92) can control the display content of the display screen 7. In another example, the control device 9 may include a single control board (circuit board and multiple control chips). That is, part of the control board is the first controller 91, and the other part is the second controller 92. This control board can control both the switching device 23 and the display content of the display screen 7.

[0125] In other words, multiple devices or apparatuses can be controlled by one device (control device 9). In the event of a failure in the control system, the failure can be quickly resolved by simply inspecting the control device 9, which provides convenience for the maintenance of the control system inside the cabinet 1.

[0126] The control device 9 can be fixed inside the cabinet 1 in any suitable manner. In the example where the charging device 100 includes a first cabinet door 141 and a second cabinet door 151, the control device 9 can be fixedly connected to the cabinet 1 via a support structure (bracket or mounting plate, etc.). For example, the circuit boards of the first controller 91 and the second controller 92 are both fixed to the support structure. The support structure can be fixed to the side 11 of the cabinet 1 (for example, one end of the support structure near the first side 111 is fixed to the first side 111 with bolts, and the other end of the support structure near the second side 112 is fixed to the second side 112 with bolts), or it can be fixed to the top of the cabinet 1 (with the control device 9 suspended inside the cabinet 1). In other words, in the various examples described above, the control device 9 can be fixed inside the cabinet 1 with the assistance of a support structure.

[0127] In an example where the charging device 100 has only one cabinet door, for instance, the charging device 100 includes a first cabinet door 141 but no longer includes a second cabinet door 151. The control device 9 can be fixed to the cabinet body 1 and the first cabinet door 141 in the second horizontal direction (second horizontal direction auxiliary reference). Figure 16 On the opposite cabinet panel, for example, the first cabinet door 141 is the front door of the cabinet 1, and the control device 9 is fixed on the back panel of the cabinet 1.

[0128] With the control device 9 fixed inside the cabinet 1, in Figure 19 In the example shown, the control device 9 and the cooling assembly 6 are distributed vertically. For example, after the control device 9 is fixed to the side 11 or the top of the cabinet 1 by a support structure, the control device 9 is positioned above the cooling assembly 6. In this example, the control device 9 can be located between the two transition assemblies 2. Figure 19 This case illustrates where the control device 9 is arranged along a first horizontal direction with any one of the adapter components 2. Alternatively, the control device 9 may be located on the side of both adapter components 2 (or any one of the adapter components 2) facing away from the first opening 14. In other examples, the control device 9 is located below the adapter component 2. In this example, the control device 9 may be located on the side of both cooling components 6 (or any one of the cooling components 6) facing away from the first opening 14 (i.e., the control device 9 is arranged along a second horizontal direction with any one of the cooling components 6, the second horizontal direction being an auxiliary reference). Figure 18 The control device 9 can also be located between two cooling components 6 (the control device 9 and any one of the cooling components 6 are arranged along the first horizontal direction).

[0129] In other examples, a transition assembly 2 and a cooling assembly 6 are provided within the cabinet 1, with the control device 9 located to the side of the transition assembly 2 in the horizontal direction, or to the side of the cooling assembly 6 in the horizontal direction. Positioning the control device 9 to the side of the cooling assembly 6 (upper, lower, left, right, etc.), or conversely, to the side of the transition assembly 2 (upper, lower, left, right, etc.), places the control device 9 within a specific area of ​​the cabinet 1, facilitating modular development of the control device 9.

[0130] In some examples, the charging device 100 also includes a radio frequency identification (RFID) device for identifying information, which is electrically connected to the control device 9 and the display screen 7.

[0131] In addition, the charging device 100 may also include a power supply device 10, as shown in the reference. Figure 19 The power supply device 10 can be a small power converter (e.g., the power supply device 10 includes a circuit board and power devices, etc.), and the power supply device 10 is connected to an external power supply 200, converting the AC power input from the power supply 200 into DC power; the power supply device 10 can also be connected to an external power conversion device 3 (power conversion device 3 is an auxiliary reference). Figure 2 The power supply device 10 steps down the DC power output from the power conversion device 3; the power supply device 10 can also be an energy storage device such as a battery, and this application does not impose specific restrictions on it.

[0132] Reference Figure 19 The power supply device 10 is located inside the cabinet 1. The power supply device 10 is electrically connected to the control device 9 (first controller 91 and second controller 92) and the display screen 7. The power supply device 10 can supply power to both the control device 9 and the display screen 7.

[0133] The power supply device 10 is fixed inside the cabinet 1. There are various ways to connect the power supply device 10 to the cabinet 1. In the example where the charging device 100 includes a first cabinet door 141 and a second cabinet door 151, the power supply device 10 can be fixedly connected to the cabinet 1 by a bracket. For example, the outer shell of the power supply device 10 is fixed to the bracket, and the end of the bracket near the first side 111 is fixed to the first side 111 by bolts, and the end of the bracket near the second side 112 is fixed to the second side 112 by bolts. The bracket can also be fixed to the top of the cabinet 1. For example, the power supply device 10 is suspended inside the cabinet 1.

[0134] In some other examples, the power supply device 10 may also be directly fixed to the side 11 of the cabinet 1. For example, without a bracket or mounting base, the power supply device 10 may be fixed to the first side 111 by bolts, or the power supply device 10 may be fixed to the second side 112 by bolts. In some other examples, the charging device 100 may have only one cabinet door. For example, the charging device 100 may include a first cabinet door 141 but no longer include a second cabinet door 151. The power supply device 10 may be fixed to the cabinet panel opposite to the first cabinet door 141. For example, the first cabinet door 141 may be the front door of the cabinet 1, and the power supply device 10 may be fixed to the back panel of the cabinet 1.

[0135] In some examples where the power supply unit 10 is fixed inside the cabinet 1, refer to Figure 19 The power supply unit 10 and the cooling assembly 6 are distributed vertically. For example, after the power supply unit 10 is fixed to the side 11 or the top of the cabinet 1 by a bracket, the power supply unit 10 is positioned above the cooling assembly 6. In this example, the power supply unit 10 can be located between two adapter assemblies 2. Figure 19 This scenario illustrates a situation where the control device 9 and any one of the adapter components 2 are arranged along a first horizontal direction. The power supply device 10 can also be located on the side of both adapter components 2 (or any one of the adapter components 2) facing away from the first opening 14. In other examples, the power supply device 10 is located below the adapter component 2. In this example, the power supply device 10 can be located on the side of both cooling components 6 (or any one of the cooling components 6) facing away from the first opening 14 (the power supply device 10 and any one of the cooling components 6 are arranged along a second horizontal direction, with the second horizontal direction as an auxiliary reference). Figure 18 In addition, the power supply device 10 may also be located between two cooling components 6 (the power supply device 10 and any one of the cooling components 6 are arranged along the first horizontal direction).

[0136] In some other examples, a transition assembly 2 and a cooling assembly 6 are provided inside the cabinet 1, with the power supply 10 located to the side of the transition assembly 2 in the horizontal direction, or the power supply 10 located to the side of the cooling assembly 6 in the horizontal direction.

[0137] The power supply device 10 is placed on the side of the cooling component 6 (upper side, lower side, left side, right side, etc.), or it can be said that the power supply device 10 is placed on the side of the adapter component 2 (upper side, lower side, left side, right side, etc.), which facilitates the modular development of the power supply device 10 and is beneficial to the overall maintenance and disassembly of the power supply device 10 inside the cabinet 1.

[0138] In addition, refer to Figure 19Alternatively, the control device 9 and the power supply device 10 can be integrated, for example, by installing them within a protective housing 110. Another example is integrating the control device 9 and the power supply device 10 onto a single circuit board, or by placing them on separate circuit boards and then centrally arranging multiple circuit boards in one area within the cabinet 1. Integrating the control device 9 and the power supply device 10 reduces their footprint within the cabinet 1, improves the utilization of the internal space, and facilitates maintenance and replacement of the control device 9 and the power supply device 10.

[0139] In some other examples, a turbulent fan (not shown in the attached drawings) may also be installed on the cabinet 1. The turbulent airflow generated by the turbulent fan can make the temperature inside the cabinet 1 more uniform and reduce the possibility of local overheating inside the cabinet 1. In some other examples, when the charging device 100 also includes a second heat exchanger 8, the turbulent fan can also blow air towards the second heat exchanger 8, so that the low temperature of the second heat exchanger 8 is dispersed inside the cabinet 1, thereby cooling the inside of the cabinet 1 and playing a role in balancing the internal temperature of the cabinet 1.

[0140] In other examples, the adapter component 2 may also include a detection device (not shown in the figures), a metering device (not shown in the figures), and other devices. The detection device (e.g., a shunt) may be connected between the switching device 23 and the output terminal 22 to detect the voltage and current of the charging circuit (i.e., the circuit formed after the charging connector 4 is connected to the device 100 to be charged). The metering device (e.g., an electricity meter) may be connected to the detection device to monitor the current and voltage in the circuit in real time, and to record and display the current value, voltage value, and changes in both in real time.

[0141] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
