Description

Technical Field

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

[0002] The trend of energy conservation and emission reduction has led to the rapid development of electric vehicles. With the popularization of electric vehicles, charging stations will become a key focus for the development of the vehicle and energy industries. Among them, charging devices such as electric heavy-duty trucks have increasingly higher requirements for the charging power and rate of charging equipment in charging stations. Therefore, it is necessary to increase the power level of charging equipment, which will require more devices or components to be installed in the equipment cabinet of the charging equipment, necessitating a high-density layout inside the charging equipment.

[0003] In related technologies, the distance between the switching devices of the charging equipment and the control board used to control the switching devices is relatively far, making it inconvenient to connect the two. Furthermore, the connection structure between the two occupies a large space, which is not conducive to a high-density layout inside the charging equipment. Utility Model Content

[0004] This application provides a charging device that achieves a high-density layout inside the charging device through the reasonable arrangement of internal components or devices.

[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 first cabinet door, a first switching device, a first charging connector, a first cable, and a first control board. The cabinet includes a first side panel and a second side panel arranged along its width, and a top panel and a bottom panel arranged along its height. The first cabinet door is connected to either the first or second side panel and has a display screen. The first switching device is located inside the cabinet and fixed to the first side panel, and its input terminal is used to electrically connect to a power source. The first charging connector is located outside the cabinet and is used to connect to a device to be charged. A portion of the first cable is located inside the cabinet and connected to the output terminal of the first switching device, while the other portion of the first cable is located outside the cabinet and connected to the charging connector. The first control board is located inside the cabinet and fixed to the first side panel, and is electrically connected to the first switching device and used to control the on / off state of the first switching device.

[0007] The input terminal of the first switching device is connected to a power source (e.g., the power grid). The current supplied by the power source, after power conversion, is input to the first switching device through its input terminal. When the first switching device is closed, it allows current to be output from its output terminal. This output current is then transmitted through a first cable to a first charging connector, which then charges the device to be charged (e.g., an electric vehicle). Positioning the first control board close to the first switching device (i.e., on the first side panel) facilitates the connection between the control board and the first switching device, shortens the length of the connection structure (e.g., electronic wires or copper busbars), and allows for more space within the equipment cabinet to accommodate more devices and equipment. This enables a high-density layout within the cabinet and facilitates the development of higher power levels for charging equipment, meeting the high-power, fast-charging needs of devices to be charged (e.g., electric heavy-duty trucks).

[0008] In one embodiment of this application, the charging device further includes a first mounting bracket, which is fixed to a first side plate, and a first switching device is fixed to the side of the first mounting bracket away from the first side plate; a first control board is fixed to the side of the first mounting bracket facing the first cabinet door; or, the first control board is at least partially located inside the first mounting bracket and disposed between the first switching device and the first side plate, and the first mounting bracket has a first opening facing the first cabinet door, the first opening being for the first control board to be inserted into or removed from the first mounting bracket.

[0009] The first cabinet door is designed as an access door. The first switching device is fixed to the side of the first mounting bracket away from the first side panel. After opening the first cabinet door, personnel can reach inside the equipment cabinet to assemble and disassemble the first switching device, facilitating maintenance and connection / removal of the first cable. Furthermore, the first control board is also fixed to the first mounting bracket, with the bracket facing the first cabinet door. Alternatively, the first control board can be inserted into the first mounting bracket, with the opening for disassembly facing the first cabinet door. This allows for easy maintenance of the first control board after opening the first cabinet door.

[0010] The first switching device and the first control board are respectively installed at different positions on the first mounting bracket. The first mounting bracket enables the first switching device and the first control board to be staggered (or stacked) in the width direction of the equipment cabinet, which improves the utilization rate of the internal space of the equipment cabinet and facilitates the maintenance of the first switching device and the first control board.

[0011] In addition, the first switching device and the first control board are fixed on the first mounting bracket. When it is necessary to disassemble the first switching device and the first control board inside the equipment cabinet, the first switching device and the first control board can be disassembled and installed separately, or the first switching device and the first control board can be disassembled and installed as a whole by disassembling and installing the first mounting bracket (other devices on the first mounting bracket will also be disassembled together).

[0012] In one embodiment of this application, the charging device further includes a first power supply device, which is used to electrically connect the power supply and the first control board. The first power supply device is used to convert the electrical energy input from the power supply into power and output it to the first control board to power the first control board. The first power supply device is fixed to the side of the first mounting bracket facing the first cabinet door. Alternatively, the first power supply device is at least partially located in the first mounting bracket and disposed between the first switching device and the first side plate. The first mounting bracket also has a second opening facing the first cabinet door, which is used for inserting the first power supply device into the first mounting bracket or removing it from the first mounting bracket.

[0013] The first switching device, the first control board, and the first power supply device are arranged in a staggered manner (or stacked) through the first mounting bracket. For example, the first control board and the first power supply device are installed behind or to the side of the first switching device, which improves the utilization rate of the internal space of the equipment cabinet and facilitates the maintenance of the first switching device, the first control board, and the first power supply device.

[0014] For example, the first power supply device is installed on the side of the first mounting bracket facing the first cabinet door. After the first cabinet door is opened, the first power supply device faces the personnel, making it convenient for personnel to maintain the first power supply device.

[0015] For example, the first power supply device is inserted into the first mounting bracket, with the second opening, which allows for the removal and installation of the first power supply device, facing the first cabinet door. Opening the first cabinet door facilitates maintenance of the first power supply device. Specifically, the first power supply device is designed to be detachable from the first mounting bracket. After opening the first cabinet door, the internal space of the equipment cabinet is connected to the external space. Personnel can pull the power supply device outwards, gradually moving it outside the equipment cabinet, thus removing it. When installation is required, the first power supply device is pushed inwards towards the first mounting bracket. After the first power supply device is inserted into the second opening, it is continuously pushed inwards towards the first mounting bracket, moving away from the first cabinet door, to complete the installation.

[0016] In one embodiment of this application, the charging device further includes a first power supply device, which is located inside the equipment cabinet and fixed to the top plate. The first power supply device is used to electrically connect the power supply and the first control board, and is used to convert the electrical energy input from the power supply into power and output it to the first control board to supply power to the first control board.

[0017] The first power supply device can also supply power to other equipment or devices. Placing the first power supply device on the top of the equipment cabinet makes it easier to connect to external devices, reduces the number of power supply devices inside the equipment cabinet, and saves internal space.

[0018] In one embodiment of this application, the first power supply device is slidable relative to the equipment cabinet in a direction that approaches or moves away from the first cabinet door.

[0019] The first power supply device is designed to slide relative to the equipment cabinet, facilitating its installation and removal. Specifically, when pulling out the first power supply device, it slides towards or away from the first cabinet door. After opening the first cabinet door, the internal space of the equipment cabinet is connected to the external space. Personnel can then pull the power supply device outwards, gradually moving it outside the equipment cabinet to remove it. To install the first power supply device, it is pushed inwards towards the equipment cabinet. Once inside the cabinet, it is continuously pushed away from the first cabinet door to complete the installation.

[0020] In one embodiment of this application, the charging device further includes a first cooling assembly, which is connected to a first side plate and located below a first switching device. The first cooling assembly includes a first driving member and a first heat exchanger. The first cable has a cooling channel for the flow of cooling medium. The first heat exchanger has a first heat exchange channel and a second heat exchange channel. The first heat exchange channel is connected to the cooling channel. The second heat exchange channel is used to connect to a cold source outside the equipment cabinet. 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 the heat of the first cable. After absorbing the heat, the cooling medium flows out of the cooling channel and enters the first heat exchange channel of the first heat exchanger. The cooling medium in the first heat exchange channel exchanges heat with the cold source medium from the cold source in the second heat exchange channel. After the heat exchange, the temperature of the cooling medium decreases and returns to the cooling channel to cool the first cable. This cycle repeats to achieve cyclic cooling of the first cable.

[0022] Furthermore, positioning the first cooling assembly below the first switching device reduces the likelihood of the cooling medium coming into contact with the first switching device in the event of a leak (e.g., coolant leakage) caused by a malfunction in the first cooling assembly, thus mitigating the risk of the first switching device failing. Additionally, since the first cooling assembly requires an external cold source, positioning it below the first switching device also reduces the length of the external cold source piping. In some cases, where the first cooling assembly is heavy, installing it at a lower position within the equipment cabinet (relative to the first switching device) reduces safety hazards during installation.

[0023] In addition, the cold source is located outside the equipment cabinet. Connecting the cold source and the first cooling component can cool the cooling medium. There is no need to set up a cold source inside the equipment cabinet, and therefore no need to open a ventilation opening on the equipment cabinet (if the cold source is set up inside the equipment cabinet, the equipment cabinet needs to be equipped with a ventilation opening to cool the cold source). This improves the protection level of the equipment cabinet and reduces the possibility of external impurities entering the equipment cabinet.

[0024] In one embodiment of this application, the charging device further includes a first receiving seat and a first drain channel; the first receiving seat is located below the first heat exchanger and is used to receive liquid from the first heat exchanger; the inlet of the first drain channel is used to communicate with the first receiving seat, and the outlet of the first drain channel is used to communicate with the external space of the equipment cabinet.

[0025] Because a low-temperature medium (e.g., a cold source medium from a cold source) flows through the first heat exchanger, while the ambient temperature inside the equipment cabinet where the first cooling component is located is high, condensate will form on the first heat exchanger. Without a condensate drainage structure, a large amount of condensate will accumulate inside the equipment cabinet. The first receiving seat provided in this application is located below the first heat exchanger and is used to collect the condensate from the first heat exchanger. By providing a first drainage channel, the condensate in the first receiving seat can be discharged outside the equipment cabinet, reducing the amount of condensate accumulating inside the equipment cabinet.

[0026] In one embodiment of this application, the portion of the first cable located inside the equipment cabinet has an interface communicating with a cooling channel. The interface is located above the first switching device, and the interface is connected to the first heat exchange channel through a pipe. The charging device also includes a blocking member, which is fixed to the first side plate and extends toward the side opposite to the first side plate. The blocking member is located between the interface and the first switching device, and is used to block liquid from flowing from the interface to the first switching device.

[0027] Since the interface needs to be connected to the first cooling component via a pipe, if the connection between the interface and the corresponding pipe becomes loose, the cooling medium will leak out and drip onto the first switching device, causing damage to the first switching device. Therefore, a blocking component is installed to block the liquid from the interface, reducing the possibility of the cooling medium leaking from the interface dripping onto the first switching device and minimizing the risk of damage to the charging equipment.

[0028] In one embodiment of this application, the first cabinet door has a first water baffle that extends toward the interior of the equipment cabinet and is located above the display screen.

[0029] After the first cabinet door is opened, the presence of the first baffle plate can block and prevent the liquid dripping from the top of the first cabinet door to a certain extent, reducing the possibility that the liquid dripping from the top of the first cabinet door will cause short circuit damage to multiple devices on the first cabinet door (e.g., the display screen).

[0030] In one embodiment of this application, the charging device further includes a second cabinet door, which is located on different sides of the device cabinet in the thickness direction, and the second cabinet door is connected to the second side panel or the first side panel.

[0031] The second cabinet door can serve as an auxiliary maintenance tool. In some cases (e.g., when opening only the first cabinet door is insufficient to meet maintenance needs), personnel can also open the second cabinet door to maintain the devices inside the equipment cabinet, thus improving the flexibility of personnel in maintaining the charging equipment.

[0032] In one embodiment of this application, the charging device further includes a turbulence fan, which is located inside the equipment cabinet and fixed to the second cabinet door. The turbulence fan is used to blow air into the equipment cabinet.

[0033] The baffle fan can eliminate localized hot spots inside the equipment cabinet, ensuring a more uniform temperature. Furthermore, placing the baffle fan on the second cabinet door makes full use of the space there, resulting in a more rational layout within the equipment cabinet.

[0034] In one embodiment of this application, the second cabinet door has a second baffle plate that extends toward the interior of the equipment cabinet and is located above the turbulence fan.

[0035] After the second cabinet door is opened, the second baffle can block and prevent the liquid dripping from the top of the second cabinet door to a certain extent, reducing the possibility that the liquid dripping from the top of the second cabinet door will cause short circuits in multiple devices on the second cabinet door (such as the turbulence fan).

[0036] In one embodiment of this application, the charging device further includes a second switching device, a second charging connector, a second cable, and a second control board. The second switching device is located inside the equipment cabinet and fixed to the second side plate, and its input terminal is used to electrically connect to a power source. The second charging connector is located outside the equipment cabinet and is used to connect to the device to be charged. A portion of the second cable is located inside the equipment cabinet and connected to the output terminal of the second switching device, while the other portion of the second cable is located outside the equipment cabinet and connected to the second charging connector. The second control board is located inside the equipment cabinet and fixed to the second side plate, and is electrically connected to the second switching device and used to control the on / off state of the second switching device.

[0037] The multiple components and devices inside the equipment cabinet are arranged on both sides, providing ample space for inspection and maintenance. Furthermore, multiple cabinet panels serve as mounting surfaces for these components and devices, improving the utilization of the internal space. Additionally, the first charging control board is located near the first switching device and controls it, while the second charging control board is located near the second switching device and controls it. This shortens the length of the connection structure between both the first and second control boards, resulting in a more rational layout within the cabinet. This allows for more space to install more devices and equipment, facilitating a high-density layout within the cabinet.

[0038] In one embodiment of this application, the charging device further includes a third control board, which is electrically connected to the display screen and is fixed to the first cabinet door or the top plate.

[0039] The display screen is fixed to the first side panel. After the equipment cabinet is installed, the display screen can face personnel so that they can observe the content on the screen. The third control board can control the display content. Placing the third control board close to the display screen facilitates connection between the third control board and the display screen. Alternatively, the third control board can be placed on the top of the equipment cabinet to make full use of the internal space and make the internal layout of the equipment cabinet more reasonable.

[0040] In one embodiment of this application, the charging device further includes a first meter for displaying charging data of the first charging connector; the first meter is fixed to the side of the first switching device facing the first cabinet door; or, the charging device further includes a second mounting bracket, the second mounting bracket is located on the side of the first switching device away from the first cabinet door, the second mounting bracket is fixed to the first side plate or the second side plate, the first meter is fixed to the side of the second mounting bracket facing the first cabinet door, and the first meter and the first switching device are offset in the width direction of the equipment cabinet.

[0041] The first meter displays the charging data of the first charging connector, thus measuring the amount of charge received by the charging equipment. Fixing the first meter on the side of the first switching device facing the first cabinet door allows personnel to directly observe the meter reading after opening the cabinet door, facilitating maintenance. Fixing the first meter on the second mounting bracket and offsetting it from the first switching device along the width of the equipment cabinet reduces the cabinet's thickness. Furthermore, the first switching device does not obstruct the first meter when the first cabinet door is open, allowing for observation and maintenance without disassembling the first switching device.

[0042] In one embodiment of this application, the charging device further includes a third cable and a base. The third cable passes through the base plate, a portion of the third cable is located inside the equipment cabinet and connected to the input terminal of the first switching device, and another portion of the third cable is located outside the equipment cabinet and used for electrical connection to the power supply. The base is fixed to the bottom of the base plate, and the top and bottom of the base have wiring ports that communicate with its own internal space. The third cable passes through the two wiring ports of the base, and the peripheral wall of the base has vents that communicate with its own internal space.

[0043] When installing equipment cabinets, the installation location typically includes trenches for cable routing (e.g., third-party cables). Since these third-party cables need to pass through the cabinet's base plate, there are openings in the base plate for them to pass through, creating a connection between the cabinet and the trench. Sometimes, liquid accumulates in the trench. If this liquid evaporates into the cabinet, it can damage the devices and components inside (e.g., primary switching devices). By installing a base with vents on it, more liquid in the trench can evaporate outwards, protecting the devices and components inside the cabinet.

[0044] In one embodiment of this application, the charging device further includes a protective cover, which is fixed inside the equipment cabinet; the protective cover is located on the side of the first switching device facing the first cabinet door, and the protective cover shields the first switching device; or, the protective cover is located on the side of the first switching device away from the first side panel, and the protective cover covers the first switching device.

[0045] After opening the first cabinet door, the protective cover can shield multiple primary switching devices, preventing them from being exposed. This protects both personnel and the switching devices, and also keeps the equipment cabinet tidy. When maintenance of the primary switching devices is required, the protective cover can be removed.

[0046] In one embodiment of this application, the charging device further includes a heat sink, which is fixed inside the equipment cabinet. The heat sink has a heat dissipation channel for connecting to a cold source outside the equipment cabinet, and the heat sink is used for heat exchange with the internal air of the equipment cabinet.

[0047] During operation, the temperature inside the charging equipment cabinet will rise. When the internal temperature of the equipment cabinet is too high, a cooling medium with cooling function is provided to the heat dissipation channel of the heat sink through a cold source. This allows the heat dissipation channel to exchange heat with the air inside the equipment cabinet, thereby reducing the internal temperature of the equipment cabinet and promoting the stable operation of the charging equipment.

[0048] In one embodiment of this application, the charging device further includes a second receiving seat and a second drain channel. The second receiving seat is located below the heat sink and is used to receive liquid from the heat sink. The inlet of the second drain channel is used to communicate with the second receiving seat, and the outlet of the second drain channel is used to communicate with the external space of the equipment cabinet.

[0049] Since a low-temperature medium (cold source medium from the cold source) flows in the radiator, while the ambient temperature inside the equipment cabinet is high, condensation will appear on the radiator. By setting a second receiving seat, the condensation dripping from the radiator can be collected and discharged to the outside of the equipment cabinet through the second drainage channel, reducing the possibility of condensation accumulating inside the equipment cabinet.

Each charging connector 5 is connected to its corresponding DC power distribution device 4 via a corresponding cable 6. The DC power distribution device 4 is installed inside the equipment cabinet 1, while the charging connectors 5 are located outside the equipment cabinet 1. The DC power distribution device 4 is used to control the on / off state of the circuit between the power conversion device 2 and the cables 6. The charging connector 5 can output the current after power conversion by the power conversion device 2.

[0084] by Figure 2 Taking charging device 01 as an example, Figure 3 An example is shown Figure 2A partial structure of the charging device 01 (the terminal part of the charging device 01). Figure 4 An example is shown Figure 3 The internal structure of the charging device 01 is referenced. Figure 3 and Figure 4 The charging device 01 includes a cabinet 1 and a first cabinet door 9. The cabinet 1 includes a first side panel 11 and a second side panel 12, which are arranged along the width direction (X-axis direction) of the cabinet 1 and are positioned opposite each other in that direction. Furthermore, the cabinet 1 includes a top plate 13 and a bottom plate 14 arranged along its height direction (Z-axis direction). It is understood that the first side panel 11, the second side panel 12, the top plate 13, and the bottom plate 14 enclose the internal space of the cabinet 1.

[0085] Reference Figure 3 and Figure 4 The first cabinet door 9 is connected to either the first side panel 11 or the second side panel 12. Figure 3 and Figure 4 An exemplary illustration shows a first cabinet door 9 connected to a first side panel 11. Furthermore, the first cabinet door 9 is rotatable relative to the equipment cabinet 1; for example, the first cabinet door 9 is hinged to the first side panel 11 (connected via a hinge). The first cabinet door 9 can open or close the equipment cabinet 1, thus serving as an access door for opening or closing the equipment cabinet 1. (Refer to...) Figure 3 When the first cabinet door 9 is closed, the equipment cabinet 1 is closed. (Refer to...) Figure 4 The first cabinet door 9, which is in the open state, is rotated to the outside of the equipment cabinet 1, thereby opening the equipment cabinet 1.

[0086] The first cabinet door 9 has a display screen 91. The display area of ​​the display screen 91 is exposed outside the equipment cabinet 1 through an opening in the first cabinet door 9. The exposed display area of ​​the display screen 91 is for personnel to observe the content displayed on the display screen 91 (e.g., billing information, charging status, etc.). After the equipment cabinet 1 is installed, the display screen 91 is oriented in a position that is easy for personnel to observe, so that personnel can see the content on the display screen 91. It can be understood that when a person stands in front of the equipment cabinet 1 facing the display screen 91, the left-right direction of the person is the width direction (X-axis direction) of the equipment cabinet 1, the front-back direction of the person is the thickness direction (Y-axis direction) of the equipment cabinet 1, and the up-down direction of the person is the height direction (Z-axis direction) of the equipment cabinet 1.

[0087] In some embodiments, refer to Figure 3The first cabinet door 9 also has a card reader 92, which is used to identify integrated circuit cards (IC cards), enabling the charging device 01 to recognize the user's IC card (bank card, charging card, etc.) and deduct the corresponding charging fee. Figure 3 In the illustrated embodiment, the card reader 92 includes an RFID reader 921 and a point-of-sale (POS) terminal 922. The identification area of ​​the RFID reader 921 is exposed outside the equipment cabinet 1, and the card insertion area and PIN input area of ​​the POS terminal 922 are also exposed outside the equipment cabinet 1. In some other embodiments, the RFID reader 921 is installed on the first cabinet door 9 without the POS terminal 922, or the POS terminal 922 is installed on the first cabinet door 9 without the RFID reader 921. In other embodiments, the card reader 92 may also be a card reader other than the two types described above.

[0088] exist Figure 3 and Figure 4 In the illustrated embodiment, the card reader 92 and the display screen 91 are arranged along the height direction (Z-axis direction) of the equipment cabinet 1. This arrangement reduces the size of the equipment cabinet 1 in the width direction (X-axis direction). In other embodiments, the card reader 92 may be located in other suitable positions.

[0089] In some embodiments, the display screen 91 and the card reader 92 can be integrated into a single module to improve the integration of the display screen 91 and the card reader 92, facilitating the overall installation or disassembly of the module formed by the integration of the display screen 91 and the card reader 92. For example, before assembling the charging device 01, the display screen 91 and the card reader 92 can be pre-fixed onto a plate-like structure, and then the plate-like structure (carrying the display screen 91 and the card reader 92) can be fixed onto the first cabinet door 9 to improve the assembly efficiency of the charging device 01.

[0090] In some embodiments, refer to Figure 3 and Figure 4 The first cabinet door 9 also has an indicator light 93, which is located above the display screen 91. The indicator light 93 is used to display the charging status of the charging device 01. For example, the indicator light 93 expresses information such as charging, standby, fault, reservation, and amount of charge through changes in color or shape.

[0091] Reference Figure 4 The DC power distribution device 4 inside the charging equipment 01 includes a first DC power distribution device 41. The first DC power distribution device 41 is installed on the first side panel 11 inside the equipment cabinet 1. After opening the first cabinet door 9, the first DC power distribution device 41 can be maintained facing the first side panel 11. Figure 5 An exemplary structure of a first DC power distribution device 41 is shown, with reference to Figure 4 and Figure 5 The first DC power distribution device 41 includes a plurality of first switching devices 411, which are located inside the equipment cabinet 1 and fixed to the first side plate 11. The plurality of first switching devices 411 are arranged along the thickness direction (Y-axis direction) of the equipment cabinet 1.

[0092] In some embodiments, refer to Figure 4 and Figure 5 To reduce the space occupied by multiple first switching devices 411 in the thickness direction of the equipment cabinet 1, adjacent first switching devices 411 can be staggered in the height direction (Z-axis direction) of the equipment cabinet 1, that is, adjacent first switching devices 411 have a height difference. In some embodiments, adjacent first switching devices 411 do not have a height difference.

[0093] In some embodiments, refer to Figure 5 The first DC power distribution device 41 further includes a plurality of first input metal busbars 412 (e.g., copper busbars or aluminum busbars) and a plurality of first output metal busbars 413 (e.g., copper busbars or aluminum busbars). Each first input metal busbar 412 is electrically connected to the input terminal of a corresponding first switching device 411, and each first output metal busbar 413 is electrically connected to the output terminal of a corresponding first switching device 411. Furthermore, in some embodiments, refer to... Figure 5 The first DC power distribution device 41 may also include a plurality of first protection devices 414 (e.g., fuses), which are fixedly connected between the output terminal of the first switching device 411 and the first output metal busbar 413. In some other embodiments, the first protection device 414 is fixedly connected between the input terminal of the first switching device 411 and the first input metal busbar 412.

[0094] Reference Figure 4 and Figure 5 The charging connector 5 includes a first charging connector 51 for connection to the first switching device 411, and the cable 6 includes a first cable 61 for connecting the first charging connector 51 and at least one first switching device 411, that is, at least one first switching device 411 is connected to the first charging connector 51 via the first cable 61. The first cable 61 passes through the equipment cabinet 1, such that a portion of the first cable 61 is located inside the equipment cabinet 1 and another portion is located outside the equipment cabinet 1.

[0095] Among them, reference Figure 4 and Figure 5 The portion of the first cable 61 located inside the equipment cabinet 1 is electrically connected to the output terminals of multiple first switching devices 411, for example, in reference... Figure 5In the illustrated embodiment, the first cable 61 has a plurality of positive wires 611 and a plurality of negative wires 612 (the plurality of positive wires 611 and the plurality of negative wires 612 are covered with an outer sheath). Each of the plurality of positive wires 611 and the plurality of negative wires 612 of the first cable 61 is electrically connected to the output terminal of a first switching device 411. When the first DC power distribution device 41 includes a plurality of first output metal busbars 413, each of the plurality of positive wires 611 and the plurality of negative wires 612 of the first cable 61 is connected to a first output metal busbar 413. In some other embodiments, the first cable 61 has one positive wire 611 and one negative wire 612 (the positive wire 611 and the negative wire 612 are covered with an outer sheath), and each of the positive wire 611 and the negative wire 612 of the first cable 61 is electrically connected to the output terminal of a first switching device 411.

[0096] The input terminal of the first switching device 411 is electrically connected to the power supply 02, for example, referring to... Figure 5 When the first DC power distribution device 41 includes multiple first input metal busbars 412, the power supply 02 is electrically connected to the first input metal busbars 412. After power conversion, the current provided by the power supply 02 is delivered to the first switching device 411 through the first input metal busbars 412. When the first switching device 411 is closed, the first switching device 411 allows current to be output from the output terminal of the first switching device 411. The current output from the output terminal of the first switching device 411 flows through the first output metal busbar 413 to the first cable 61, and is delivered to the corresponding first charging connector 51 through the first cable 61. Then, the device to be charged is charged through the first charging connector 51.

[0097] In addition, refer to Figure 4 and Figure 5 The charging device 01 also includes a first control board 101, which is located inside the equipment cabinet 1 and fixed to the first side plate 11. The first control board 101 is electrically connected to the first switching device 411 and is used to control the on / off state of the first switching device 411. The first control board 101 includes a circuit board and multiple electronic components (including a control chip), and the multiple electronic components of the first control board 101 are fixed on the circuit board of the first control board 101.

[0098] The first control board 101 is positioned on the first side plate 11, close to the first switching device 411. This facilitates the connection between the first control board 101 and the first switching device 411, shortens the length of the connection structure (e.g., electronic wire or copper busbar) between the first control board 101 and the first switching device 411, and allows for more space in the equipment cabinet 1 to install more devices and equipment. This enables a high-density layout within the equipment cabinet 1 and facilitates the development of the power level of the charging equipment 01 to a higher power level, meeting the high-power fast charging needs of the device to be charged 01 (e.g., an electric heavy-duty truck).

[0099] The first switching device 411 and the first control board 101 can be mounted on the first side plate 11 in any suitable manner, for example... Figure 6 An exemplary structure of a first mounting bracket 201 is shown, with reference to Figure 6 The charging equipment 01 also includes a first mounting bracket 201. The specific structure of the first mounting bracket 201 can be configured according to requirements. For example, the first mounting bracket 201 can be formed by bending a metal plate, or the first mounting bracket 201 can be formed by multiple metal rods fixed and overlapping each other. The first mounting bracket 201 is fixed to the first side plate 11, and the first switching device 411 is fixed to the side of the first mounting bracket 201 opposite to the first side plate 11. After opening the first cabinet door 9, personnel can reach into the equipment cabinet 1 to disassemble and assemble the first switching device 411, which is beneficial for maintenance of the first switching device 411 and for connecting or disconnecting the first cable 61 from the first switching device 411.

[0100] In one embodiment, reference is made to... Figure 6 The first control board 101 is fixed to the side of the first mounting bracket 201 facing the first cabinet door 9. After opening the first cabinet door 9, personnel can maintain the first control board 101 by facing the inside of the equipment cabinet 1.

[0101] In another embodiment, Figure 7 An exemplary embodiment shows another structure of the first mounting bracket 201, in which the first control board 101 is at least partially located within the first mounting bracket 201 and disposed between the first switching device 411 and the first side plate 11, for example, referring to Figure 7 The first control board 101 is located inside the first mounting bracket 201. In this embodiment, the first control board 101 can be fixed to the first mounting bracket 201 by fasteners such as bolts, and the first control board 101 can also be fixed to the first side plate 11 by fasteners such as bolts.

[0102] Reference Figure 7The first mounting bracket 201 has a first opening 2011 facing the first cabinet door 9. The first opening 2011 is used for inserting or removing the first control board 101 from the first mounting bracket 201. The first opening 2011 for assembling and disassembling the first control board 101 faces the first cabinet door 9. After opening the first cabinet door 9, the internal space of the equipment cabinet 1 is connected to the external space, allowing personnel to insert and remove the first control board 101 through the first opening 2011 for maintenance. For example, personnel can remove the first control board 101 by pulling it outwards and gradually moving it outside the equipment cabinet 1; when it is necessary to install the first control board 101, the first control board 101 is inserted into the first opening 2011 and pushed towards the inside of the first mounting bracket 201 to complete the installation of the first control board 101.

[0103] Reference Figure 6 and Figure 7 The first switching device 411 and the first control board 101 are respectively installed at different positions on the first mounting bracket 201. The first mounting bracket 201 allows the first switching device 411 and the first control board 101 to be staggered in the width direction (X-axis direction) of the equipment cabinet 1, or the first switching device 411 and the first control board 101 to be stacked in the width direction of the equipment cabinet 1, which improves the utilization rate of the internal space of the equipment cabinet 1 and facilitates the maintenance of the first switching device 411 and the first control board 101.

[0104] Furthermore, the first switching device 411 and the first control board 101 are fixed on the first mounting bracket 201. When it is necessary to disassemble the first switching device 411 and the first control board 101 inside the equipment cabinet 1, the first switching device 411 and the first control board 101 can be disassembled and installed separately, or the first mounting bracket 201 can be disassembled and installed as a whole to achieve the disassembly and assembly of the first switching device 411 and the first control board 101.

[0105] In addition, other components on the first mounting bracket 201 can also be disassembled or installed. For example, multiple devices or components included in the first DC power distribution device 41 (first protection device 414, first input metal busbar 412, first output metal busbar 413, etc.) can all be installed on the first mounting bracket 201, making the integration of the first DC power distribution device 41 in the equipment cabinet 1 higher and significantly improving the installation efficiency and subsequent maintenance efficiency of the charging equipment 01. During the installation of the first DC power distribution device 41, the first DC power distribution device 41 can be assembled independently first, that is, the first switching device 411, the first protection device 414, the first input metal busbar 412, and the first output metal busbar 413 are all fixed on the first mounting bracket 201, and then the first mounting bracket 201 is installed on the first side plate 11. In this way, the first DC power distribution device 41 can be installed as a whole on the first side plate 11. During the maintenance of the first DC power distribution device 41, the first DC power distribution device 41 can be completely disassembled and replaced by disassembling the first mounting bracket 201.

[0106] In some embodiments, refer to Figure 6 The charging device 01 also includes a first power supply device 301, which is used to electrically connect the power supply 02 and the first control board 101. The first power supply device 301 is used to convert the electrical energy input from the power supply 02 into power and output it to the first control board 101 to supply power to the first control board 101. Figure 6 In the illustrated embodiment, the first power supply device 301 is located between the first switching device 411 and the first side plate 11 and is at least partially located within the first mounting bracket 201. For example, a portion of the first power supply device 301 is inserted into the first mounting bracket 201. The first mounting bracket 201 also has a second opening 2012 facing the first cabinet door 9, which is used for inserting or removing the first power supply device 301 from the first mounting bracket 201. After opening the first cabinet door 9, the internal space of the equipment cabinet 1 is connected to the external space. Personnel can pull the first power supply device 301 outwards and gradually move it outside the equipment cabinet 1 to disassemble the first power supply device 301. When it is necessary to install the first power supply device 301, insert the first power supply device 301 into the second opening 2012 and push it into the first mounting bracket 201 (the first power supply device 301 and the first mounting bracket 201 can be fixed with bolts after insertion) to complete the installation of the first power supply device 301.

[0107] In some other embodiments, reference is made to Figure 7The first power supply device 301 is located outside the first mounting bracket 201, and the first power supply device 301 is fixed to the side of the first mounting bracket 201 facing the first cabinet door 9. After the first cabinet door 9 is opened, the first power supply device 301 is oriented towards personnel, making it convenient for personnel to maintain the first power supply device 301.

[0108] Furthermore, in some embodiments, reference is made to Figure 7 The charging device 01 also includes a first meter 401, which displays the charging data of the first charging connector 51 to measure the amount of charge received by the charging device 01. The first meter 401 can detect the charging data of the first charging connector 51 using any suitable method. For example, the first DC power distribution device 41 also includes a first shunt 415, which can be a metal busbar (e.g., copper or aluminum). The first shunt 415 is fixed to the first input metal busbar 412 or the first output metal busbar 413 and is electrically connected to the first meter 401. By detecting the current flowing through the first shunt 415, the first meter 401 can determine the magnitude of the current flowing through the first input metal busbar 412 or the first output metal busbar 413, thereby detecting the corresponding charging data of the first charging connector 51.

[0109] The first meter 401 can be fixed in any suitable location. In one embodiment, refer to... Figure 6 or Figure 7 The first meter 401 is fixed to the side of the first switching device 411 facing the first cabinet door 9. For example, when the charging equipment 01 includes the first mounting bracket 201, the first meter 401 is fixed to the side of the first mounting bracket 201 facing the second cabinet door 100, so that the first meter 401 is located on the side of the first switching device 411 facing the second cabinet door 100. After opening the first cabinet door 9, personnel can directly observe the value of the first meter 401, which is also conducive to personnel maintaining the first meter 401.

[0110] In another embodiment, the charging device 01 further includes a second mounting bracket 202. Figure 8 An exemplary structure of a second mounting bracket 202 is shown, with reference to Figure 8The second mounting bracket 202 is located on the side of the first switch device 411 facing away from the first cabinet door 9. One end of the second mounting bracket 202 in the width direction (X-axis direction) of the equipment cabinet 1 is fixedly connected to the first side plate 11, and the other end of the second mounting bracket 202 is fixedly connected to the second side plate 12. The first meter 401 is fixed to the side of the second mounting bracket 202 facing the first cabinet door 9, and the first meter 401 and the first switch device 411 are offset in the width direction of the equipment cabinet 1. By offsetting the first meter 401 and the first switch device 411 in the width direction of the equipment cabinet 1, the thickness of the equipment cabinet 1 can be reduced. Furthermore, after the first cabinet door 9 is opened, the first switch device 411 will not obstruct the first meter 401, and the first meter 401 can be observed and inspected without disassembling the first switch device 411.

[0111] It should be noted that, Figures 6 to 8 The installation methods of the first switching device 411, the first control board 101, the first power supply device 301, and the first meter 401 shown can be used in any combination. For example, in the charging device 01, the first control board 101 is used in... Figure 6 The solution is installed on the first mounting bracket 201, and the first power supply device 301 is used to... Figure 7 The first meter 401 is installed on the first mounting bracket 201 in a manner that allows it to be used in the same way. Figure 8 The solution is installed on the second mounting bracket 202.

[0112] In some embodiments, refer to Figure 8 The DC power distribution device 4 inside the charging equipment 01 also includes a second DC power distribution device 42. The second DC power distribution device 42 is installed on the second side panel 12 inside the equipment cabinet 1. After opening the second cabinet door 100, the second DC power distribution device 42 can be maintained by facing the second side panel 12. Figure 9 An exemplary structure of a second DC power distribution device 42 is shown, with reference to Figure 9 The second DC power distribution device 42 includes a plurality of second switching devices 421, which are located inside the equipment cabinet 1 and fixed to the second side plate 12. The plurality of second switching devices 421 are arranged along the thickness direction (Y-axis direction) of the equipment cabinet 1.

[0113] In some embodiments, to reduce the space occupied by the multiple second switching devices 421 in the thickness direction of the equipment cabinet 1, adjacent second switching devices 421 can be staggered in the height direction (Z-axis direction) of the equipment cabinet 1. In other embodiments, adjacent first switching devices 411 are not staggered.

[0114] In some embodiments, refer to Figure 8The second DC power distribution device 42 further includes a plurality of second input metal busbars 422 (e.g., copper or aluminum busbars) and a plurality of second output metal busbars 423 (e.g., copper or aluminum busbars). Each second input metal busbar 422 is electrically connected to the input terminal of a corresponding second switching device 421, and each second output metal busbar 423 is electrically connected to the output terminal of a corresponding second switching device 421. Furthermore, in some embodiments, the second DC power distribution device 42 also includes a plurality of second protection devices 424 (e.g., fuses). The second protection devices 424 are fixedly connected between the output terminal of the second switching device 421 and the second output metal busbars 423, or the second protection devices 424 are fixedly connected between the input terminal of the second switching device 421 and the second input metal busbars 422.

The second cable 62 passes through the equipment cabinet 1, with one part of the second cable 62 located inside the equipment cabinet 1 and the other two parts located outside the equipment cabinet 1. The portion of the second cable 62 located inside the equipment cabinet 1 is electrically connected to the output terminals of the plurality of second switching devices 421, and has a connection method similar to that of the first cable 61 and the plurality of first switching devices 411, which will not be described in detail here.

[0116] In this configuration, the input terminal of the second switching device 421 is electrically connected to the power supply 02. When the second DC power distribution device 42 includes multiple second input metal busbars 422 and multiple second output metal busbars 423, the power supply 02 is electrically connected to the second input metal busbars 422. After power conversion, the current provided by the power supply 02 is delivered to the second switching device 421 through the second input metal busbars 422. When the second switching device 421 is closed, the second switching device 421 allows current to be output from its output terminal. The current output from the output terminal of the second switching device 421 flows through the second output metal busbars 423 to the second cable 62, and is then delivered to the corresponding second charging connector 52 through the second cable 62. The device to be charged is then charged through the second charging connector 52.

[0117] In addition, the charging device 01 also includes a second control board 102, which is located inside the equipment cabinet 1 and fixed to the second side plate 12. The second control board 102 is electrically connected to the second switching device 421 and is used to control the on / off state of the second switching device 421. The second control board 102 includes a circuit board and multiple electronic components (including a control chip), and the multiple electronic components of the second control board 102 are fixed on the circuit board of the second control board 102.

[0118] The second control board 102 is positioned on the second side plate 12, close to the second switching device 421. This facilitates the connection between the second control board 102 and the second switching device 421, shortens the length of the connection structure (e.g., electronic wire or copper busbar) between the second control board 102 and the second switching device 421, and allows for more space in the equipment cabinet 1 to install more devices and equipment, thus achieving a high-density layout within the equipment cabinet 1.

[0119] The second switching device 421 and the second control board 102 can be mounted on the second side plate 12 in any suitable manner, for example, referring to Figure 8 The charging device 01 also includes a third mounting bracket 203. The third mounting bracket 203 can be configured according to requirements. For example, the third mounting bracket 203 can be formed by bending a metal plate, or it can be formed by multiple metal rods that are fixed and overlapped together. In some embodiments, the third mounting bracket 203 has the same structure as the first mounting bracket 201. The third mounting bracket 203 is fixed to the second side plate 12, and the second switching device 421 is fixed to the side of the third mounting bracket 203 opposite to the second side plate 12. After opening the first cabinet door 9, it is convenient for personnel to maintain the second switching device 421.

After opening the first cabinet door 9, personnel can maintain the second control board 102 when facing the inside of the equipment cabinet 1.

[0121] In another embodiment, refer to Figure 9 , Figure 9 The third mounting bracket 203 in the middle and Figure 8 The third mounting bracket 203 is different; refer to... Figure 9 The second control board 102 is at least partially located within the third mounting bracket 203 and disposed between the second switching device 421 and the second side plate 12. For example, the second control board 102 is entirely located within the third mounting bracket 203. In this embodiment, the second control board 102 can be fixed to the third mounting bracket 203 by bolts or other fasteners, and the second control board 102 can also be fixed to the second side plate 12 by bolts or other fasteners. The third mounting bracket 203 has a third opening 2031 facing the first cabinet door 9 (the position of the first cabinet door 9 is an auxiliary reference). Figure 8The third opening 2031 is used for inserting or removing the second control board 102 into or from the third mounting bracket 203. The third opening 2031 for assembling and disassembling the second control board 102 faces the first cabinet door 9, allowing personnel to perform maintenance on the second control board 102 by inserting or removing it through the third opening 2031 after the first cabinet door 9 is opened.

[0122] Reference Figure 8 and Figure 9 The second switch device 421 and the second control board 102 are respectively installed at different positions on the third mounting bracket 203, which improves the utilization rate of the internal space of the equipment cabinet 1 and facilitates the maintenance of the second switch device 421 and the second control board 102.

[0123] Furthermore, in some embodiments, reference is made to Figure 8 and Figure 9 Other devices or components included in the first DC power distribution device 41 (second input metal busbar 422, second output metal busbar 423, second protection device 424, etc.) are all installed on the third mounting bracket 203, which makes the integration of the second DC power distribution device 42 in the equipment cabinet 1 higher and greatly improves the installation efficiency and subsequent maintenance efficiency of the charging equipment 01.

[0124] In some embodiments, refer to Figure 8 The charging device 01 also includes a second power supply device 302, which is used to electrically connect the power supply 02 and the second control board 102. The second power supply device 302 is used to convert the electrical energy input from the power supply 02 into power and output it to the second control board 102 to power the second control board 102. Figure 8 In the illustrated embodiment, the second power supply device 302 is at least partially located within the third mounting bracket 203 and disposed between the second switching device 421 and the second side plate 12. For example, a portion of the second power supply device 302 is inserted into the third mounting bracket 203. The third mounting bracket 203 also has a fourth opening 2032 facing the first cabinet door 9, which is used for inserting the second power supply device 302 into or removing it from the third mounting bracket 203.

[0125] In some other embodiments, reference is made to Figure 9 The second power supply device 302 is located outside the third mounting bracket 203, and the second power supply device 302 is fixed to the side of the third mounting bracket 203 facing the first cabinet door 9 (the position of the first cabinet door 9 is for reference). Figure 8 After opening the first cabinet door 9, position the second power supply device 302 so that it faces the personnel, making it easier for them to maintain the second power supply device 302.

[0126] Furthermore, in some embodiments, a reference is returned. Figure 8 The charging device 01 also includes a second meter 402, which displays the charging data of the second charging connector 52 to measure the amount of charge received by the charging device 01. The second meter 402 can detect the charging data of the second charging connector 52 using any suitable method. For example, the second DC power distribution device 42 also includes a second shunt 425, which can be a metal busbar (e.g., copper or aluminum). The second shunt 425 is fixed to the second input metal busbar 422 or the second output metal busbar 423 and is electrically connected to the second meter 402. By detecting the current flowing through the second shunt 425, the second meter 402 can determine the magnitude of the current flowing through the second input metal busbar 422 or the second output metal busbar 423, thereby detecting the corresponding charging data of the second charging connector 52.

[0127] The second meter 402 can be fixed in any suitable location. In one embodiment, refer to... Figure 8 The second meter 402 is fixed to the side of the second mounting bracket 202 facing the first cabinet door 9. Furthermore, the second meter 402 and the second switch device 421 are offset in the width direction (X-axis direction) of the equipment cabinet 1, thereby reducing the thickness of the equipment cabinet 1. Also, the second switch device 421 will not obstruct the second meter 402. Figure 8 In the illustrated embodiment, the first meter 401 and the second meter 402 are arranged along the height of the equipment cabinet 1. In another embodiment, refer to... Figure 9 The second meter 402 is fixed to the side of the second switch device 421 facing the second cabinet door 100. For example, when the charging equipment 01 includes a third mounting bracket 203, the second meter 402 is fixed to the side of the third mounting bracket 203 facing the second cabinet door 100, so that the second meter 402 is located on the side of the second switch device 421 facing the second cabinet door 100. After opening the first cabinet door 9, personnel can directly observe the value of the first meter 401, which is also conducive to personnel maintaining the first meter 401.

[0128] It should be noted that, Figure 8 and Figure 9 The installation methods of the second switching device 421, the second control board 102, the second power supply device 302, and the second meter 402 shown can be used in any combination. For example, in the charging device 01, the second control board 102 is used in... Figure 8 The solution is installed on the third mounting bracket 203, and the second power supply device 302 is used to... Figure 7 The second meter 402 is installed on the third mounting bracket 203 in a manner that allows it to be installed in the same way. Figure 8 The solution is installed on the second mounting bracket 202.

[0129] The first switching device 411, the first control board 101 and other structures are installed on the first side plate 11, and the second switching device 421, the second control board 102 and other structures are installed on the second side plate 12. The equipment cabinet 1 adopts a two-sided layout, so that multiple devices and devices have sufficient space to be directly disassembled for maintenance.

[0130] In some embodiments, only one power supply device can be provided to power the first control board 101 and the second control board 102, reducing the number of power supply devices in the equipment cabinet 1 and saving internal space in the equipment cabinet 1. For example, Figure 10 An exemplary structure of a first power supply device 301 is shown, with reference to Figure 10 Unlike the aforementioned various first power supply devices 301, this first power supply device 301 is located inside the equipment cabinet 1 and fixed to the top plate 13 (e.g., fixed to the top plate 13 by a bracket or mounting bracket). Furthermore, this first power supply device 301 is used to electrically connect the power supply 02, the first control board 101, and the second control board 102. The first power supply device 301 converts the electrical energy input from the power supply 02 and outputs it to the first control board 101 and the second control board 102 to supply power. In addition, this first power supply device 301 can also electrically connect to and supply power to the display screen 91. Placing the first power supply device 301 on the top of the equipment cabinet 1 facilitates external wiring. In some embodiments, the first power supply device 301 can slide relative to the equipment cabinet 1 in a direction close to or away from the first cabinet door 9 to facilitate plugging and unplugging the first power supply device 301.

[0131] In some embodiments, the first control board 101 and the second control board 102 can also be used for communication between the device to be charged 01 (e.g., a vehicle) and the charging device 01, including interactions such as vehicle voltage, current, and alarm signals.

[0132] In addition, return to reference Figure 8 The charging device 01 also includes a third control board 103, which includes a circuit board and multiple electronic components (including a control chip). The multiple electronic components of the third control board 103 are fixed to the circuit board of the third control board 103. The third control board 103 is electrically connected to the display screen 91 and is fixed to the first cabinet door 9. For example, the third control board 103 is fixed to a bracket, which is also fixed to the first cabinet door 9. With the support of the bracket, the third control board 103 is positioned on the side of the display screen 91 facing away from the first cabinet door 9. Positioning the third control board 103 close to the display screen 91 facilitates connection between the third control board 103 and the display screen 91. Furthermore, refer to... Figure 10Alternatively, the third control board 103 can be placed on top of the equipment cabinet 1 (top plate 13) to make full use of the internal space of the equipment cabinet 1 and make the internal layout of the equipment cabinet 1 more reasonable. In the case where the charging device 01 includes a host part and a terminal part, the third control board 103 is also used to communicate with the terminal part.

[0133] In some other embodiments, the third control board 103 is disposed on the top plate 13 of the equipment cabinet 1, the first control board 101 is fixed to the first side plate 11, and the second control board 102 is fixed to the first side plate 12.

[0134] In some embodiments, return to reference Figure 8 The first cabinet door 9 has a first baffle 94, which extends towards the interior space of the equipment cabinet 1 (with the first cabinet door 9 closed as a reference). The first baffle 94 is located above the display screen 91. When the first cabinet door 9 is equipped with a third control board 103, the first baffle 94 is also located above the third control board 103. After the first cabinet door 9 is opened, the first baffle 94 can block and prevent liquid dripping from the top of the first cabinet door 9 to a certain extent, reducing the possibility of short circuit damage to the display screen 91 and the third control board 103 caused by the liquid dripping from the top of the first cabinet door 9.

[0135] In some embodiments, the charging device 01 is used to charge heavy-duty trucks and other charging devices that require high-power fast charging. The first cable 61 carries a large current and needs to be cooled. The first cable 61 has a channel for the flow of a cooling medium, as shown in the figure. Figure 10 The charging device 01 also includes a first cooling component 50, which is connected to the first side plate 11 and located below the first switching device 411. The first cooling component 50 is connected to an external cold source 03 and is used to provide a cooling medium for the first cable 61 and drive the cooling medium to flow.

[0136] By positioning the first cooling assembly 50 below the first switching device 411, the likelihood of the cooling medium coming into contact with the first switching device 411 is reduced in the event of a malfunction in the first cooling assembly 50 leading to leakage (e.g., cooling medium leakage), thus mitigating the risk of the first switching device 411 malfunctioning. Furthermore, since the first cooling assembly 50 requires an external cold source 03, positioning it below the first switching device 411 also reduces the length of the piping for the external cold source 03. Additionally, in some cases where the first cooling assembly 50 is heavy, installing it at a lower position within the equipment cabinet 1 (lower than the first switching device 411) reduces safety hazards during installation.

[0137] The first cooling component 50 can be any suitable structure with the above-described functions, for example... Figure 11 An exemplary structure of a first cooling assembly 50 is shown, with reference to Figure 10 and Figure 11 The first cooling assembly 50 includes a first drive 501 (e.g., a water pump) and a first heat exchanger 502 (e.g., a plate heat exchanger). The first heat exchanger 502 has a first heat exchange channel 5021 and a second heat exchange channel 5022. The first cable 61 has a cooling channel 613 for the flow of cooling medium. The first heat exchange channel 5021 communicates with the cooling channel 613, and the second heat exchange channel 5022 is used to connect to a cold source 03 outside the equipment cabinet 1. The first drive 501 communicates with the first heat exchange channel 5021 and the cooling channel 613, and the first drive 501 is used to drive the cooling medium to circulate between the first heat exchange channel 5021 and the cooling channel 613. After the cooling medium enters the cooling channel 613 from the first heat exchange channel 5021, it absorbs the heat from the first cable 61. After absorbing the heat, the cooling medium flows out of the cooling channel 613 and enters the first heat exchange channel 5021 of the first heat exchanger 502. The cooling medium in the first heat exchange channel 5021 exchanges heat with the cold source medium from the cold source 03 in the second heat exchange channel 5022. After the heat exchange, the temperature of the cooling medium decreases and it returns to the cooling channel 613 to cool the first cable 61. This cycle repeats to achieve cyclic cooling of the first cable 61.

[0138] It should be noted that the cold source 03 is located outside equipment cabinet 1 (for reference only). Figure 4 It is connected to the first cooling component 50 through a pipe. The first cooling component 50 can cool the cooling medium by connecting to the cold source 03. There is no need to set up the cold source 03 in the equipment cabinet 1, and there is no need to open a ventilation port on the equipment cabinet 1 (if the cold source 03 is set up in the equipment cabinet, the equipment cabinet 1 needs to set up a ventilation port to cool the cold source 03, for example, to cool the condenser of the cold source 03). This improves the protection level of the equipment cabinet 1 and reduces the possibility of external impurities entering the equipment cabinet 1.

[0139] In addition, in some embodiments, the first cooling assembly 50 also includes a liquid storage tank for containing the cooling medium, and liquid level and water temperature sensors located at least partially within the liquid storage tank, etc., which are not limited in this application.

[0140] Because a low-temperature medium (e.g., a cold source medium from cold source 03) flows through the first heat exchanger 502, while the ambient temperature inside the equipment cabinet 1 where the first cooling assembly 50 is located is high, condensate will appear on the first heat exchanger 502 (condensate may also appear on the first drive component 501). Without a condensate drainage structure, a large amount of condensate will accumulate inside the equipment cabinet 1. In some embodiments, the charging device 01 further includes a first receiving seat 601 and a first drain channel 602. Figure 12 An exemplary structure of a first receiving seat 601 and a first drain channel 602 is shown. The first receiving seat 601 is located below the first heat exchanger 502 (or possibly below the first driving member 501), and is used to receive liquid from the first heat exchanger 502. The inlet of the first drain channel 602 is used to communicate with the first receiving seat 601, and the outlet of the second drain channel 605 is used to communicate with the external space of the equipment cabinet 1. Through the first drain channel 602, the condensate in the first receiving seat 601 can be discharged to the outside of the equipment cabinet 1, reducing the amount of condensate accumulating inside the equipment cabinet 1.

[0141] In some embodiments, the first receiving seat 601 may be the base of a funnel-shaped pile. In other embodiments, the first receiving seat 601 may also be part of other structures, for example, referring to... Figure 12 The charging device 01 also includes a fixing base 603, which is fixed to the first side plate 11. The first cooling component 50 is located inside the fixing base 603, and the first receiving base 601 is the bottom structure of the fixing base 603.

[0142] In some other embodiments, reference is made to Figure 12 The first cooling assembly 50 also includes an assembly housing 503. The first drive unit 501 and the first heat exchanger 502 are both located within the assembly housing 503. The assembly housing 503 is mounted within a fixed base 603 and can slide relative to the fixed base 603 in a direction approaching or moving away from the first cabinet door 9. When maintaining the first cooling assembly 50, the first cabinet door 9 is opened, and the assembly housing 503 can be moved relative to the equipment cabinet 1 by pulling or other means. The assembly housing 503 can then be gradually pulled out of the equipment cabinet 1, allowing for inspection or replacement of the first heat exchanger 502 and the first drive unit 501 within the assembly housing 503. This facilitates maintenance of the first cooling assembly 50 and reduces the time required for maintenance. After maintenance of the first cooling assembly 50 is completed, the assembly housing 503 is pushed back into the fixed base 603 until it is reinstalled, thus completing the reinstallation of the first cooling assembly 50.

[0143] Among them, reference Figure 12 The bottom of the component housing 503 has a drain hole 5031. After the condensate from the first heat exchanger 502 drips to the bottom of the component housing 503, it will flow into the first receiving seat 601 through the drain hole 5031 and be discharged to the outside of the equipment cabinet 1 through the first drain channel 602.

[0144] It should be noted that the first drainage channel 602 can be any channel structure capable of draining liquid. For example, the bottom of the first receiving seat 601 is connected to a pipe structure, and the first drainage channel 602 includes the internal channel of the pipe structure.

[0145] Furthermore, in some embodiments, the second cable 62 also has a channel for the flow of cooling medium (the structure is the same as or similar to that of cooling channel 613), see reference. Figure 13 The charging device 01 also includes a second cooling component 70. Figure 13 An exemplary structure of a second cooling assembly 70 is shown. The second cooling assembly 70 is connected to the second side plate 12 and located below the second switching device 421. The second cooling assembly 70 is externally connected to a cold source 03 and is used to provide cooling medium to the channel for the flow of cooling medium in the second cable 62 and to drive the flow of cooling medium.

[0146] The second cooling component 70 can be any suitable structure with the above-mentioned functions. For example, the second cooling component 70 includes a second drive (e.g., a water pump) and a second heat exchanger (similar or the same as the first heat exchanger 502). The second cooling component 70 can be the same as the first cooling component 50 to achieve cyclic cooling of the second cable 62, which will not be elaborated here.

[0147] Furthermore, in some embodiments, the charging device 01 also includes a structure for draining condensate from the second heat exchanger. For example, the charging device 01 also includes a third receiving seat (same as or similar to the first receiving member) and a third drain channel (same as or similar to the first drain channel 602) to reduce the amount of condensate accumulating in the equipment cabinet 1, which will not be described in detail here.

[0148] In order to connect the first cable 61 to the first cooling assembly 50, the portion of the first cable 61 located inside the equipment cabinet 1 has an interface 63 that connects to the cooling channel 613. Figure 14 An exemplary structure of interface 63 is shown, with reference to Figure 14 Interface 63 is located above the first switching device 411, and interface 63 is connected to the first heat exchange channel 5021 through cooling pipe 631 (or can be referred to for further information). Figure 11 In some embodiments, refer to Figure 13 and Figure 14 The charging device 01 also includes a blocking member 80, which is fixed to the first side plate 11 and extends toward the side opposite to the first side plate 11. At least a portion of the blocking member 80 is located between the interface 63 and the first switching device 411. The blocking member 80 is used to block liquid from flowing from the interface 63 to the first switching device 411.

[0149] The blocking member 80 can be any structure capable of achieving the above-mentioned functions. In one embodiment, refer to... Figure 13 The blocking member 80 can be a plate-shaped structure, and the end of the blocking member 80 away from the first side plate 11 extends to the side of the first switching device 411 away from the first side plate 11, so that the blocking member 80 can completely cover the first switching device 411.

[0150] In another embodiment, refer to Figure 14 The blocking member 80 has a receiving cavity 801 and an opening 802 communicating with the receiving cavity 801. The opening 802 is disposed away from the first switching device 411, located below the interface 63, and is used to receive liquid from the interface 63. Furthermore, the blocking member 80 also has an overflow port 803 communicating with the receiving cavity 801. The overflow port 803 is located below the opening 802. In the width direction of the equipment cabinet 1, the overflow port 803 is located between the first switching device 411 and the first side plate 11. For example, in the case where the charging device 01 includes a first mounting bracket 201, the overflow port 803 is located directly above the first mounting bracket 201. The overflow port 803 is used to drain liquid from the receiving cavity 801. Liquid dripping from the overflow port 803 will drip onto the first mounting bracket 201 instead of the first switching device 411, reducing the possibility of damage to the first switching device 411.

[0151] in, Figure 14 The blocking member 80 shown can be assembled from multiple plates. For example, the blocking member 80 includes a first baffle 804, a second baffle 805, and two third baffles 806. The surface of the first baffle 804 is parallel to the horizontal plane, and the first baffle 804 is located between the interface 63 and the first switching device 411. The second baffle 805 is fixed to the first baffle 804 and arranged with the first side plate 11 along the width direction (X-axis direction) of the equipment cabinet 1. The second baffle 805 protrudes towards the side of the first baffle 804 away from the first switching device 411. The two third baffles 806 are arranged along the thickness direction (Y-axis direction) of the equipment cabinet 1. Both second baffles 805 are fixed to the first baffle 804 and both protrude towards the side of the first baffle 804 away from the first switching device 411. The first baffle 804, the second baffle 805, and the two third baffles 806 form a receiving cavity 801. In addition, each third baffle 806 has a gap with the first side plate 11, which is an overflow outlet 803.

[0152] In some other embodiments, the overflow outlet 803 may also be located at the bottom of the block 80.

[0153] In addition, a structure similar to the blocking member 80 can also be provided on the second side plate 12 to reduce the possibility of the cooling medium in the second cable 62 dripping onto the second switching device 421. This application will not elaborate further on this.

[0154] Because some components inside the equipment cabinet 1 generate heat during use, causing the internal temperature of the equipment cabinet 1 to rise, and excessively high temperatures inside the equipment cabinet 1 pose certain risks (such as accelerated component aging, short circuits, etc.), therefore, in some examples, the charging device 01 also includes a heat sink 90. Figure 15 An exemplary structure of a heat sink 90 is shown, with reference to Figure 15 The radiator 90 is fixed inside the equipment cabinet 1. The radiator 90 has a heat dissipation channel 901, which connects to a cold source 03 outside the equipment cabinet 1. The radiator 90 exchanges heat with the internal air of the equipment cabinet 1. When the internal temperature of the cabinet is too high, a cooling medium (cold source medium from the cold source 03) is introduced into the heat dissipation channel 901 of the radiator 90. The cold source medium flows within the heat dissipation channel 901 and exchanges heat with the internal air of the equipment cabinet 1, thus reducing the internal temperature of the equipment cabinet 1. The radiator 90 can be any device with a heat dissipation channel 901 capable of exchanging heat with the internal air of the equipment cabinet 1, such as a plate heat exchanger, a tubular heat exchanger, etc.

[0155] exist Figure 15 In the example shown, where the equipment cabinet 1 has a first cooling assembly 50 and a second cooling assembly 70, the radiator 90 is disposed between the first cooling assembly 50 and the second cooling assembly 70. In some other examples, where the equipment cabinet 1 has a first cooling assembly 50 but no second cooling assembly 70, the radiator 90 is disposed on one side of the first cooling assembly 50 in the width direction (X-axis direction) of the equipment cabinet 1.

[0156] In addition, the charging device 01 also includes a cooling fan 902 (shaded portion refers to the cooling fan 902) disposed in the device cabinet 1. The cooling fan 902 is disposed on one side of the heat sink 90 (for example, on one side of the heat sink 90 in the thickness direction of the device cabinet 1). The cooling fan 902 is used to drive airflow over the heat sink 90. ​​The cooling fan 902 can blow air towards the heat sink 90 or it can draw air in.

[0157] Because a low-temperature medium (cold source medium from cold source 03) flows through the radiator 90, while the ambient temperature inside the equipment cabinet 1 is high, condensation will occur on the radiator 90. In some embodiments, the charging device 01 further includes a second receiving seat 604 and a second drain channel 605. The second receiving seat 604 is located below the radiator 90 and is used to receive liquid from the radiator 90. The inlet of the second drain channel 605 is connected to the second receiving seat 604, and the outlet of the second drain channel 605 is connected to the external space of the equipment cabinet 1. By providing the second receiving seat 604, the condensation dripping from the radiator 90 can be received, and the condensation can be discharged to the outside of the equipment cabinet 1 through the second drain channel 605, reducing the possibility of condensation accumulating inside the equipment cabinet 1.

[0158] The second receiving seat 604 can be any structure capable of receiving condensate, for example, refer to Figure 15 The second receiving seat 604 can be the base of a funnel-shaped pile. In some other embodiments, the second receiving seat 604 can also be part of other structures, for example, the radiator 90 is located inside a housing, and the bottom of the housing forms the second receiving seat 604. Furthermore, the second drainage channel 605 can be any channel-like structure capable of draining liquid; for example, the bottom of the second receiving seat 604 is connected to a pipe-like structure, and the second drainage channel 605 includes the internal channel of that pipe-like structure.

[0159] Charging device 01 also includes a second cabinet door 100. Figure 16 An exemplary second cabinet door 100 is shown, with reference to Figure 16 The second cabinet door 100 and the first cabinet door 9 are located on different sides of the equipment cabinet 1 along its thickness direction. The second cabinet door 100 is connected to the second side panel 12 or the first side panel 11. Figure 1 The diagram shows the second cabinet door 100 connected to the second side panel 12. The second cabinet door 100 is rotatable relative to the equipment cabinet 1; for example, the second cabinet door 100 is hinged to the second side panel 12 (connected by a hinge). The second cabinet door 100 can open or close the equipment cabinet 1. The second cabinet door 100 can serve as an auxiliary maintenance tool. In some cases (e.g., when opening only the first cabinet door 9 is insufficient for maintenance), personnel can also open the second cabinet door 100 to maintain the devices in the equipment cabinet 1, improving the flexibility of personnel maintenance of the charging equipment 01.

[0160] In some embodiments, refer to Figure 16The charging device 01 also includes a baffle fan 1001, which is located inside the equipment cabinet 1 and fixed to the second cabinet door 100. The baffle fan 1001 is used to blow air into the equipment cabinet 1. For example, the baffle fan 1001 blows air into the parts of the equipment cabinet 1 that are overheating, which can eliminate local hot spots inside the equipment cabinet 1 and make the temperature inside the equipment cabinet 1 more uniform. The placement of the baffle fan 1001 on the second cabinet door 100 makes full use of the space on the second cabinet door 100, resulting in a more rational layout inside the equipment cabinet 1. Using the first side panel 11, the second side panel 12, the first cabinet door 9, and the second cabinet door 100 as mounting surfaces for devices and apparatus further improves the utilization rate of the internal space of the equipment cabinet 1.

[0161] With a deflector fan 1001 installed on the second cabinet door 100, refer to Figure 16 The second cabinet door 100 also has a second baffle 1002, which is fixed to the second cabinet door 100 and extends towards the interior space of the equipment cabinet 1 (with the second cabinet door 100 closed as a reference). The second baffle 1002 is located above the baffle fan 1001. When the second cabinet door 100 is opened, the presence of the second baffle 1002 can block and prevent liquid dripping from the top of the second cabinet door 100 to a certain extent, reducing the possibility of damage to the baffle fan 1001 caused by the liquid dripping from the top of the second cabinet door 100.

[0162] In other embodiments, the charging device 01 also includes a structure capable of shielding the first switching device 411; for example, the charging device 01 also includes a protective cover 200. Figure 17 An exemplary structure of a protective shield 200 is shown, with reference to Figure 17 The protective cover 200 is fixed inside the equipment cabinet 1, and the protective cover 200 is located on multiple first switching devices 411 ( Figure 17 The protective cover 200 shields the first DC power distribution device 41 (including multiple first switching devices 411) on the side facing the first cabinet door 9. In other words, after the first cabinet door 9 is opened, the protective cover 200 prevents the first DC power distribution device 41 from being exposed, thus protecting both personnel and the first DC power distribution device 41, and also making the inside of the equipment cabinet 1 more tidy.

[0163] The protective cover 200 can be fixed inside the equipment cabinet 1 by any suitable means. Figure 17In the illustrated embodiment, the protective cover 200 is fixedly connected to the first side plate 11 near its edge (e.g., by bolts), and the protective cover 200 is fixedly connected to the second side plate 12 near its edge (e.g., by bolts). In other embodiments, the protective cover 200 is fixed (e.g., by bolts) to the first side plate 11, and the protective cover 200 is not connected to the second side plate 12; or, the protective cover 200 is fixed (e.g., by bolts) to the second side plate 12, and the protective cover 200 is not connected to the first side plate 11. When the first switching device 411 needs maintenance, the protective cover 200 can be disassembled.

[0164] In the case where the charging device 01 also includes a second cabinet door 100, the side of the first switching device 411 facing the second cabinet door 100 may also be provided with a protective structure similar to the protective cover 200 (same or similar to the structure of the protective cover 200). That is, when the second cabinet door 100 is opened, the protective structure can also shield the first DC power distribution device 41.

[0165] Figure 18 An exemplary structure of a protective shield 200 is shown. Figure 18 This is a top view of charging device 01, see reference. Figure 18 The protective cover 200 is fixed inside the equipment cabinet 1 and located on the side of the first switching device 411 opposite to the first side plate 11. For example, the protective cover 200 is fixed to the first side plate 11. Or, for example, if the charging device 01 includes a first mounting bracket 201, the protective cover 200 is fixed to the first mounting bracket 201. The protective cover 200 covers the first switching device 411. The protective cover 200 protects the first switching device 411. Furthermore, a similar protective structure (with the same or similar structure as the protective cover 200) can also be provided on the side of the second switching device 421 opposite to the second cabinet door 100, covering the second switching device 421.

[0166] In some embodiments, the first switching device 411 (and the second switching device 421) are connected to the power supply 02 via wires, for example, see reference 1. Figure 4 and Figure 5The charging device 01 also includes a third cable 300, which passes through the base plate 14. A portion of the third cable 300 is located inside the equipment cabinet 1 and connected to the input terminal of the first switching device 411, while another portion of the third cable 300 is located outside the equipment cabinet 1 and is used to connect to the power supply 02. When the equipment cabinet 1 is installed, a trench for placing the wires (e.g., the third cable 300) is usually provided at the location where the equipment cabinet 1 is installed, for example, a trench is provided in the ground. Since the third cable 300 needs to pass through the base plate 14 of the equipment cabinet 1, there will be an opening on the base plate 14 for the third cable 300 to pass through. Sometimes liquid accumulates in the trench. If the liquid evaporates into the equipment cabinet 1 through the opening on the base plate 14 for the third cable 300 to pass through, it may damage the devices and components (e.g., the first switching device 411) inside the equipment cabinet 1.

[0167] Therefore, in some embodiments, reference is made to Figure 17 The charging device 01 also includes a base 400, which is fixed to the bottom of the base plate 14. The base 400 has an internal space (or internal chamber). Both the bottom and top of the base 400 are provided with cable routing ports 401 that communicate with its internal space. The portion of the third cable 300 located outside the equipment cabinet 1 also passes through the two cable routing ports 401 of the base 400. Furthermore, the peripheral wall of the base 400 also has vents 402 that communicate with its internal space. By providing vents 402 on the base 400, more liquid in the trench can evaporate outwards through the vents 402, thus protecting the devices and components inside the equipment cabinet 1.

[0168] The base 400 can be any suitable structure. In some embodiments, the base 400 is a square frame and includes four interconnected plates that enclose the internal space of the base 400. At least one of the four plates has an air vent 402. The top of the frame-type base 400 abuts against the bottom plate 14 of the equipment cabinet 1, and the top and bottom of the base 400 each have an opening, which is a cable routing port 401. In other embodiments, the base 400 is a cuboid and includes six plates located on different sides (top, bottom, left, right, front, and rear), which enclose the internal space of the base 400. The plate above the base 400 (the top of the base 400) abuts against the bottom plate 14 of the equipment cabinet 1, and both the plate above the base 400 (the top of the base 400) and the plate below the base 400 (the bottom of the base 400) are provided with cable routing ports 401. In addition, apart from the plate above and the plate below the base 400, at least one of the remaining four plates (left, right, front and rear plates) of the base 400 has an air vent 402.

[0169] In addition, in some embodiments, the bottom plate 14 of the equipment cabinet 1 may be provided with a sealing structure to seal the opening of the bottom plate 14 through which the third cable 300 passes, thereby improving the protection level of the equipment cabinet 1.

[0170] In addition, return to reference Figure 3 The charging device 01 also includes a charging gun holder 600, the number of which is the same as the number of charging connectors 5, for example, in Figure 3 In the illustrated embodiment, two gun holders 600 are provided and fixed to the first cabinet door 9. The two gun holders 600 are arranged along the width direction (X-axis direction) of the equipment cabinet 1. One gun holder 600 is used for inserting the first charging connector 51, and the other gun holder 600 is used for inserting the second charging connector 52. When the charging connector 5 is not in use, it can be inserted into the corresponding gun holder 600.

[0171] With the gun mount 600 fixed to the first cabinet door 9, the arrangement of the gun mount 600 and the display screen 91 can be configured according to requirements. For example, refer to... Figure 3 The two gun mounts 600 are located below the display screen 91. This arrangement reduces the size of the equipment cabinet 1 in the width direction (X-axis direction) and reduces the floor space occupied by the equipment cabinet 1.

[0172] In some other embodiments, Figure 19 An exemplary arrangement of a gun holder 600 is shown, wherein a gun holder 600 for inserting a first charging connector 51 is disposed on a first side plate 11, and a gun holder 600 for inserting a second charging connector 52 is disposed on a second side plate 12. In some other embodiments, Figure 20 An exemplary location of another gun mount 600 is shown, all gun mounts 600 being disposed on the second side plate 12 (or all disposed on the first side plate 11).

[0173] In some other embodiments, the gun holder 600 may not be mounted on the equipment cabinet 1, but may be supported on one side of the equipment cabinet 1 by a support structure. In this embodiment, there is a gap between the gun holder 600 and the equipment cabinet 1.

[0174] In some embodiments, each charging port 600 is provided with a return switch (e.g., a micro switch). When the charging connector 5 is inserted into the corresponding charging port 600, the return switch on that charging port 600 is triggered. When the charging connector 5 is removed from the corresponding charging port 600, the return switch on the charging port 600 is released. The charging device 01 can determine whether the charging connector 5 is inserted into the charging port 600 by detecting whether the return switch on the charging port 600 is triggered.

[0175] To allow the first cable 61 and the second cable 62 to pass smoothly through the equipment cabinet 1, the equipment cabinet 1 is provided with a cable outlet 15. In some embodiments, refer to Figure 19 The outlet hole 15 of the first cable 61 is located on the first side plate 11, and the outlet hole 15 of the second cable 62 is located on the second side plate 12. This allows the first cable 61 and the second cable 62 to exit from the nearest location, shortening the length of the first cable 61 and the second cable 62 remaining inside the equipment cabinet 1. In other embodiments, refer to... Figure 20 The cable outlet 15 of the first cable 61 and the cable outlet 15 of the second cable 62 are both located on the second side plate 12 (or both are located on the first side plate 11).

[0176] In some embodiments, the charging device 01 may further include an emergency stop button 500, which can control the charging device 01 to stop charging in the event of an emergency during use of the charging device 01. The emergency stop button 500 can be located in any suitable position. Figure 16 In the illustrated embodiment, the emergency stop button 500 is fixed to the first side panel 11. In other embodiments, the emergency stop button 500 is fixed to the second side panel 12, the first cabinet door 9, or the second cabinet door 100. In other embodiments, the charging device 01 may not include the emergency stop button 500.
