Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, and in particular to a charging pile. Background Technology

[0002] Charging stations, especially high-power charging stations, typically need to integrate multiple power modules to meet high-power charging demands. In existing charging stations, the power modules are usually electrically connected to the input and output components via cables, and the side walls of the charging station enclosure are equipped with cable management channels for routing the cables.

[0003] However, due to the large number of power modules and their different installation locations, there are many types and lengths of cables, and the cable management channels take up a lot of space, resulting in complex wiring, difficult cable management, and limited operating space. Utility Model Content

[0004] Therefore, it is necessary to provide a charging pile that addresses the above problems by providing convenient internal wiring and a large operating space.

[0005] This utility model provides a charging pile, comprising: a housing; an input component disposed within the housing, the input component including a first input terminal and a first output terminal arranged perpendicular to the height direction of the housing, the first input terminal being used to input current; an input copper busbar assembly disposed within the housing and extending along the height direction of the housing, the input copper busbar assembly being electrically connected to the first output terminal; multiple power modules disposed within the housing and stacked along the height direction of the housing, each power module including a second input terminal and a second output terminal, each second input terminal being electrically connected to the input copper busbar assembly; an output copper busbar assembly disposed within the housing and extending along the height direction of the housing, each second input terminal being electrically connected to the output copper busbar assembly; and an output component disposed within the housing, the output component being electrically connected to the output copper busbar assembly and used to output current.

[0006] In the aforementioned charging pile, since the power modules are stacked along the height of the enclosure, and both the input and output copper busbars extend along the height of the enclosure, the second input and second output terminals of each power module can be centrally connected to the input and output copper busbars, significantly reducing the number of cables. Furthermore, the simple and regular structure of the input and output copper busbars eliminates the need for cable management channels, thereby simplifying the wiring process and improving installation efficiency. At the same time, since the first input and first output terminals of the input components are arranged perpendicular to the height of the enclosure, the space occupied by the input components along the height of the enclosure is reduced, and it is also convenient to electrically connect the first output terminal to the input copper busbars. This makes the internal structure of the enclosure more compact, increases the operating space, and facilitates installation and maintenance.

[0007] In one embodiment, the input copper busbar group and the output copper busbar group are arranged opposite to each other on both sides of the power module; the second input terminal and the second output terminal of each power module are arranged at intervals along the height direction perpendicular to the housing, and the second input terminal is arranged close to the input copper busbar group, and the second output terminal is arranged close to the output copper busbar group.

[0008] This design makes wiring easier, avoids cross-wiring and tangling between different wiring structures, and makes the wiring inside the enclosure more organized and clear, facilitating installation and maintenance. At the same time, it also prevents the input and output copper busbars from blocking the heat dissipation channels of the power module, ensuring normal heat dissipation and stable operation of the power module.

[0009] In one embodiment, the input copper busbar group has multiple input positions, each of which is spaced apart along the height direction of the enclosure and corresponds to a power module. Each second input terminal is electrically connected to the corresponding input position. The output copper busbar group has multiple output positions, each of which is spaced apart along the height direction of the enclosure and corresponds to a power module. Each second output terminal is electrically connected to the corresponding output position.

[0010] This configuration allows each power module's second input and second output terminals to be independently and conveniently connected to their corresponding input and output positions. Furthermore, the wiring positions and methods for each power module are identical, and the input and output positions are easily located by the user during wiring, thus simplifying the wiring process.

[0011] In one embodiment, each of the second input terminals is electrically connected to the corresponding input bit via a cable, and each of the second output terminals is electrically connected to the output bit via a cable.

[0012] This configuration allows for greater flexibility in the cable installation, making the connection of each power module more flexible. The connection method is simple, requiring only input and output cables of different lengths.

[0013] In one embodiment, the input component is located at the top or bottom of the power module, and the input component further includes a circuit breaker and a first connecting copper busbar group; the first input terminal and the first output terminal are respectively located on both sides of the circuit breaker along the height direction perpendicular to the housing, one end of the first connecting copper busbar group is electrically connected to the first output terminal, and the other end is electrically connected to the top or bottom end of the input copper busbar group.

[0014] This configuration allows the input components to make full use of the space in the enclosure, resulting in a more compact overall structure for the charging station. It also improves the wiring position and expands the operating space. The first connecting copper busbar ensures stable and reliable transmission of high current, and its route is neat and clear, facilitating installation and maintenance.

[0015] In one embodiment, the output component is located on the side of the output copper busbar group away from the power module. The output component includes a second connecting copper busbar group and an output component. The two ends of the second connecting copper busbar group are electrically connected to one end of the output component and the output copper busbar group, respectively. The other end of the output component can extend out of the housing.

[0016] This configuration makes the wiring path of the second connecting copper busbar group direct and simple, improving charging efficiency and reducing the impact of heat generated by the power module on the output components. The second connecting copper busbar group can ensure stable and reliable transmission of large current, and its route is neat and clear, making it convenient for installation and maintenance.

[0017] In one embodiment, the output device includes a charging gun and a charging cable. The charging gun is located outside the housing. One end of the charging cable is electrically connected to the second connecting copper busbar, and the other end extends out of the housing and is electrically connected to the charging gun.

[0018] This design allows the charging gun to be easily connected to external devices to be charged, and the flexible charging cable makes it easy for users to operate the charging gun, improving its flexibility.

[0019] In one embodiment, the output component further includes a mounting plate disposed on the inner wall of the housing, and the output copper busbar group and the second connecting copper busbar group are respectively disposed on two sides of the mounting plate.

[0020] This design makes the internal structure of the enclosure more compact and orderly, and the mounting plate can isolate the output components from other structures inside the enclosure, reducing the impact of the heat generated by the power module on the output components, while also preventing the gun wire from interfering with other structures inside the enclosure.

[0021] In one embodiment, the number of output copper busbar groups is at least two, and each output copper busbar group is arranged at intervals along the height direction of the enclosure. Each output copper busbar group is electrically connected to the second output terminal of a portion of the power module. The number of output components is at least two, and they correspond one-to-one with the output copper busbar groups. Each output component is electrically connected to the corresponding output copper busbar group.

[0022] This configuration allows the charging station to charge multiple devices simultaneously and to flexibly allocate power, expanding the range of applicable devices. Each output copper busbar group is independent and does not interfere with each other, improving the reliability of the charging station and facilitating installation and maintenance.

[0023] In one embodiment, the input copper busbar group is a three-phase copper busbar, and the output copper busbar group is a positive and negative copper busbar.

[0024] This setup is suitable for DC charging stations that convert AC power to DC power. Attached Figure Description

[0036] Charging piles, especially high-power charging piles, typically integrate multiple power modules to meet high-power charging demands. In existing charging piles, power modules are usually electrically connected to input and output components via cables, and the side walls of the charging pile enclosure have cable management channels for routing the cables. However, due to the large number of power modules and their varying installation locations, the number and length of cables are diverse, and the cable management channels occupy a significant amount of space, resulting in complex wiring, difficult cable management, and limited operating space. For example, a 480kW DC charging pile typically requires 12 power modules, each with three-phase input, resulting in at least 36 cables of varying lengths passing through the cable management channels on the input side.

[0037] To solve the above problems, such as Figures 1 to 4 As shown, this utility model provides a charging pile with convenient internal wiring and a large operating space.

[0038] like Figures 1 to 3 As shown, specifically, the charging pile includes a housing 1, an input component 2, an input copper busbar assembly 3, an output copper busbar assembly 5, an output component 6, and multiple power modules 4. The input component 2 is located inside the housing 1 and includes a first input terminal 21 and a first output terminal 22 arranged perpendicular to the height of the housing 1. The first input terminal 21 is used for electrical connection to an external power source to input current. The input copper busbar assembly 3 is located inside the housing 1 and extends along the height of the housing 1. The input copper busbar assembly 3 is electrically connected to the first output terminal 22. Connection; multiple power modules 4 are disposed inside the housing 1 and stacked along the height direction of the housing 1. Each power module 4 includes a second input terminal 41 and a second output terminal 42. Each second input terminal 41 is electrically connected to the input copper busbar group 3. An output copper busbar group 5 is disposed inside the housing 1 and extends along the height direction of the housing 1. Each second input terminal 41 is electrically connected to the output copper busbar group 5. An output component 6 is disposed in the housing 1. The output component 6 is electrically connected to the output copper busbar group 5 and is used to electrically connect to an external device to be charged in order to output current.

[0039] In this design, the height direction of box 1 is defined as the Z-axis direction shown in the diagram, and the direction perpendicular to the height of box 1 is the direction parallel to the XOY plane. In practical use, the height direction of box 1 is vertical, and the direction perpendicular to the height of box 1 is horizontal. Alternatively, box 1 can be placed horizontally as needed, meaning the height direction of box 1 is horizontal, and the direction perpendicular to the height of box 1 is vertical.

[0040] In the charging pile provided by this utility model embodiment, since each power module 4 is stacked along the height direction of the housing 1, and the input copper busbar group 3 and the output copper busbar group 5 both extend along the height direction of the housing 1, the second input terminal 41 and the second output terminal 42 of each power module 4 can be centrally connected to the input copper busbar group 3 and the output copper busbar group 5, which significantly reduces the number of cables. In addition, the structure of the input copper busbar group 3 and the output copper busbar group 5 is simple and regular, which can eliminate the need for cable tray structure, thereby simplifying the wiring process and improving installation efficiency. At the same time, since the first input terminal 21 and the first output terminal 22 of the input component 2 are arranged along the height direction perpendicular to the housing 1, the space occupied by the input component 2 along the height direction of the housing 1 can be reduced, and it is also convenient to electrically connect the first output terminal 22 to the input copper busbar group 3, thereby making the structure inside the housing 1 more compact, increasing the operating space, and facilitating installation and maintenance.

[0041] Electrical connections can be achieved between the first input terminal 21 and the external power supply, between the input copper busbar group 3 and the first output terminal 22, between each second input terminal 41 and the input copper busbar group 3, between each second input terminal 41 and the output copper busbar group 5, between the output copper busbar group 5 and the output component 6, and between the output component 6 and the external device to be charged, through wiring structures such as cables 7, copper busbars, and connectors. No specific limitations are imposed on this embodiment of the utility model.

[0042] like Figures 2 to 3 As shown, in one embodiment, the input copper busbar group 3 and the output copper busbar group 5 are arranged opposite each other on both sides of the power module 4; the second input terminal 41 and the second output terminal 42 of each power module 4 are arranged at intervals along the height direction perpendicular to the housing 1, with the second input terminal 41 arranged close to the input copper busbar group 3 and the second output terminal 42 arranged close to the output copper busbar group 5. In the illustrated embodiment, the input copper busbar group 3 and the output copper busbar group 5 are arranged opposite each other on both sides of the power module 4 along the Y-axis direction. This shortens the distance between the second input terminal 41 and the input copper busbar group 3, and the distance between the second output terminal 42 and the output copper busbar group 5, making wiring more convenient. It also avoids the crossover and tangling of the wiring structures, making the internal layout of the housing 1 more regular and clear, facilitating installation and maintenance. At the same time, the input copper busbar group 3 and the output copper busbar group 5 are located on both sides of the power module 4, which also avoids blocking the heat dissipation channel of the power module 4, ensuring the normal heat dissipation and stable operation of the power module 4. Of course, in other embodiments, the input copper busbar group 3 and the output copper busbar group 5 can also be located on the same side of the power module 4, and the second input terminal 41 and the second output terminal 42 of the power module 4 can also be arranged at intervals along the height direction of the housing 1, as long as they can be wired normally and do not affect the normal operation and heat dissipation of the power module 4. This embodiment of the present invention does not impose specific limitations here.

[0043] like Figure 2 As shown, in one embodiment, the input copper busbar group 3 has multiple input positions 31, each input position 31 is arranged at intervals along the height direction of the housing 1, and corresponds one-to-one with the power module 4. Each second input terminal 41 is electrically connected to the corresponding input position 31. Figure 3As shown, the output copper busbar group 5 has multiple output positions 51, which are spaced apart along the height direction of the housing 1 and correspond one-to-one with the power modules 4. Each second output terminal 42 is electrically connected to the corresponding output position 51. This allows each power module 4's second input terminal 41 and second output terminal 42 to be independently and conveniently wired to their corresponding input position 31 and output position 51. Furthermore, the wiring positions and methods of each power module 4 are identical, and the wiring structure specifications are uniform. The input position 31 and output position 51 are also easily located by the user during wiring, further simplifying the wiring process, reducing costs, improving installation and maintenance efficiency, and avoiding cross-cutting and tangling between wiring structures. Of course, in other embodiments, two, three, or more power modules 4 can share a set of input positions 31 and output positions 51. Alternatively, the input copper busbar group 3 and the output copper busbar group 5 may not have explicitly defined input positions 31 and output positions 51, and the second input terminal 41 and second output terminal 42 of the power module 4 can be electrically connected to any position on the input copper busbar group 3 and the output copper busbar group 5.

[0044] like Figures 2 to 3 As shown in the illustrated embodiment, each second input terminal 41 is electrically connected to its corresponding input position 31 via cable 7, and each second output terminal 42 is electrically connected to its output position 51 via cable 7. Cable 7 has a certain degree of flexibility, allowing for slight alignment deviations during installation, making the installation of each power module 4 more flexible. At the same time, the connection method of cable 7 is simple, requiring only two lengths of cable 7 (input and output), simplifying the cable part number and further simplifying the wiring process, improving installation and maintenance efficiency, and reducing costs.

[0045] like Figure 2As shown, in one embodiment, the input component 2 is located at the top or bottom of the power module 4. The input component 2 also includes a circuit breaker 23 and a first connecting copper busbar group 24. The first input terminal 21 and the first output terminal 22 are respectively located on both sides of the circuit breaker 23 along the height direction perpendicular to the housing 1. One end of the first connecting copper busbar group 24 is electrically connected to the first output terminal 22, and the other end is electrically connected to the corresponding top or bottom end of the input copper busbar group 3. In the illustrated embodiment, the input component 2 is located at the bottom of the power module 4. The first input terminal 21 and the first output terminal 22 are respectively located on both sides of the circuit breaker 23 along the X-axis direction. The end of the first connecting copper busbar group 24 away from the first output terminal 22 is electrically connected to the bottom end of the input copper busbar group 3. Specifically, the first connecting copper busbar group 24 can be fixed and electrically connected to the first output terminal 22 and the input copper busbar group 3 using fasteners such as screws and bolts. Thus, the input component 2 can fully utilize the space at the top or bottom of the power module 4, and the horizontal arrangement of the circuit breaker 23 can fully utilize the horizontal space of the housing 1, making the overall structure of the charging pile more compact. It also raises the wiring position and expands the operating space, facilitating the installation and maintenance of the circuit breaker 23. Simultaneously, the electrical connection between the first output terminal 22 and the input copper busbar group 3 via the first connecting copper busbar group 24 ensures stable and reliable transmission of large currents. Furthermore, the regular and clear routing of the first connecting copper busbar group 24 facilitates installation and maintenance, improving the safety of the charging pile. Of course, in other embodiments, the input component 2 can also be located on the side of the input copper busbar group 3 away from the power module 4, or in other positions within the housing 1, as long as normal wiring is possible and it does not affect the normal operation and heat dissipation of the power module 4. This embodiment of the present invention does not impose specific limitations here.

[0046] Furthermore, the input copper busbar group 3 can be fixedly supported to the inner wall of the enclosure 1 by a support column, and the circuit breaker 23 can be fixed to the inner wall of the enclosure 1 by fasteners such as screws and bolts. The two ends of the first connecting copper busbar group 24 are fixed to the input copper busbar group 3 and the first output end 22 respectively to support the first connecting copper busbar group 24; or, the first connecting copper busbar group 24 can also be fixedly supported to the inner wall of the enclosure 1 by a support column.

[0047] like Figures 2 to 3As shown, in one embodiment, the output component 6 is located on the side of the output copper busbar group 5 facing away from the power module 4. The output component 6 includes a second connecting copper busbar group 62 and an output component 61. Both ends of the second connecting copper busbar group 62 are electrically connected to one end of the output component 61 and the output copper busbar group 5, respectively, and the other end of the output component 61 can extend out of the housing 1. Specifically, the second connecting copper busbar group 62 can be fixed and electrically connected to the output copper busbar group 5 and the output component 61 using fasteners such as screws and bolts. Thus, the output component 6 is positioned close to the output copper busbar group 5, making the wiring path of the second connecting copper busbar group 62 direct and simple, effectively reducing power loss, improving charging efficiency, and reducing the impact of heat generated by the power module 4 on the output component 6, thereby improving the reliability of the charging pile. Simultaneously, the electrical connection between the output copper busbar group 5 and the output component 61 via the second connecting copper busbar group 62 ensures stable and reliable transmission of high current, and the neat and clear routing of the second connecting copper busbar group 62 facilitates installation and maintenance, improving the safety of the charging pile. Of course, in other embodiments, the output component 6 can also be located at the top, bottom or other position inside the housing 1 of the power module 4, as long as it can be wired normally and does not affect the normal operation and heat dissipation of the power module 4. This utility model embodiment does not impose specific limitations here.

[0048] The first connecting copper busbar group 24 and the second connecting copper busbar group 62 can be a single copper busbar structure of straight copper busbar, L-shaped copper busbar or other shapes, or a copper busbar group structure formed by connecting multiple copper busbars of different shapes and sizes. The interconnected copper busbars can be fixed with fasteners such as screws and bolts and electrically connected.

[0049] like Figures 2 to 3 As shown in the illustrated embodiment, the output component 61 includes a charging gun (not shown) and a charging cable. The charging gun is located outside the housing 1 and is used to output current. One end of the charging cable is electrically connected to the second connecting copper busbar group 62, and the other end extends out of the housing 1 and is electrically connected to the charging gun. The charging gun facilitates connection to external devices to be charged, and the charging cable has a certain degree of flexibility, making it easy for users to operate the charging gun and improving flexibility. Of course, in other embodiments, the output component 61 can also be a cable or other structure such as a terminal, wherein the terminal can be fixed to the outer wall of the housing 1.

[0050] like Figures 2 to 4As shown, in one embodiment, the output component 6 further includes a mounting plate 8 disposed on the inner wall of the housing 1, with the output copper busbar group 5 and the second connecting copper busbar group 62 respectively disposed on both sides of the mounting plate 8. Thus, the mounting plate 8 supports and fixes the output copper busbar group 5 and the second connecting copper busbar group 62, ensuring the reliability of the output copper busbar group 5 and the output component 6, making the structure inside the housing 1 more compact and orderly; simultaneously, the mounting plate 8 can isolate the output component 6 from other structures inside the housing 1, further reducing the impact of heat generated by the power module 4 on the output component 6, and also preventing interference between the gun wire and other structures inside the housing 1. Furthermore, the output copper busbar group 5, the output component 6, and the mounting plate 8 can be disassembled and maintained as a whole for user operation. Specifically, the mounting plate 8 is provided with clearance holes 81, through which part of the second connecting copper busbar group 62 can pass and be electrically connected to the output copper busbar group 5. Of course, in other embodiments, the output copper busbar group 5 and the second connecting copper busbar group 62 can also be fixedly supported on the inner wall of the housing 1 by support columns.

[0051] like Figures 3 to 4 As shown, there are at least two output copper busbar groups 5, each arranged at intervals along the height direction of the housing 1. Each output copper busbar group 5 is electrically connected to the second output terminal 42 of a portion of the power module 4. There are at least two output components 6, each corresponding to one of the output copper busbar groups 5, and each output component 6 is electrically connected to its corresponding output copper busbar group 5. In this way, the power of the entire charging pile can be allocated to different output components 6 as needed, enabling the charging pile to charge multiple devices simultaneously and flexibly allocate power, thus expanding the applicability of the equipment. At the same time, each output copper busbar group 5 is independent and does not interfere with each other. When one output copper busbar group 5 or output component 6 fails, it will not affect the normal operation of other groups, thereby improving the reliability of the charging pile and facilitating installation and maintenance. In the illustrated embodiment, there are two output copper busbar groups 5 and two output components 6. The two output components 61 extend from the two side walls of the housing 1 along the X-axis direction, making the two output components 61 independent and non-interfering with each other.

[0052] like Figures 2 to 3As shown, in one embodiment, the charging pile is a DC charging pile. External power is input via the first input terminal 21 (AC), which is then output from the first output terminal 22 after passing through the circuit breaker 23. The AC current flows through the first connecting copper busbar group 24 to the input copper busbar group 3. The input copper busbar group 3 transmits the current to each power module 4 via the second input terminal 41. The power module 4 converts the AC current to DC current and outputs it to the output copper busbar group 5 via the second output terminal 42. The output copper busbar group 5 transmits the current to the output component 61 via the second connecting copper busbar group 62, and the output component 61 charges the device to be charged. At this time, when three-phase AC power is input, the input copper busbar group 3 is a three-phase copper busbar, and the output copper busbar group 5 is a positive and negative copper busbar. Specifically, the input copper busbar group 3 includes three parallel and spaced copper busbars, the first connecting copper busbar group 24 also has three copper busbars, and the first input terminal 21, the first output terminal 22, and the second input terminal 41 of each power module 4 also have three terminals; the output copper busbar group 5 includes two parallel and spaced copper busbars, the second connecting copper busbar group 62 also has two copper busbars, and the second output terminal 42 of each power module 4 has two terminals. Of course, in other embodiments, when unidirectional AC power is input, the input copper busbar group 3 is a unidirectional AC copper busbar; the external power supply can also directly input DC power, in which case the input copper busbar group 3 is a positive and negative copper busbar; or, the charging pile can also be an AC charging pile, in which case the output copper busbar group 5 is a unidirectional AC copper busbar or a three-phase copper busbar.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
