Description

Technical Field

[0001] This application relates to the field of high-power charging, and more particularly to a high-power charging cabinet. Background Technology

[0002] As vehicles become increasingly important in people's lives, their numbers have exploded. This has brought with it pollution and energy consumption problems associated with traditional gasoline-powered vehicles. Especially in the context of peak carbon emissions and carbon neutrality, electric vehicles (EVs) stand out due to their use of clean energy sources. However, since current EVs use batteries as their onboard energy storage medium, charging the batteries has become a crucial aspect of their operation.

[0003] In recent years, high-power charging cabinets have been developed, with total output power exceeding 300kW. Compared to traditional low-power charging cabinets, they not only offer higher total output power but also provide faster charging speeds and a smaller footprint. This allows electric vehicle users to enjoy shorter charging times and serve more users within a limited charging area, significantly improving the user experience. However, existing high-power charging cabinets are often designed and installed as a single unit. In particular, the power distribution components, which control the power distribution between each terminal and the charging gun, are also individually installed within the cabinet, forming a single unit. If a malfunction occurs or upgrades to the power distribution components are needed due to technological advancements, all components must be disassembled, undoubtedly increasing the difficulty of upgrading and maintaining high-power charging cabinets. Therefore, a technical solution is needed that enables convenient maintenance and replacement of the power distribution components in high-power charging cabinets. Summary of the Invention

[0004] This application provides a high-power charging cabinet to address the inconvenience of maintaining and replacing the power distribution components in existing high-power charging cabinets.

[0005] To achieve the above objectives, this application provides a high-power charging cabinet, comprising: a cabinet body, a parallel assembly, a first power matrix module, and a second power matrix module. The parallel assembly is fixed inside the cabinet body and positioned at the midpoint of the cabinet body's width direction. The parallel assembly includes at least one pair of parallel copper busbar assemblies, at least one pair of parallel device assemblies corresponding to the at least one pair of parallel copper busbar assemblies, and a parallel sheet metal assembly. Each pair of parallel copper busbar assemblies includes parallel positive input copper busbars and parallel negative input copper busbars parallel to each other in the width direction of the cabinet body. The parallel device assembly is positioned at the midpoint of the parallel positive input copper busbars and parallel negative input copper busbars in the width direction of the cabinet body.

[0006] The first power matrix module and the second power matrix module are respectively fixed on both sides of the at least one pair of parallel copper busbar assemblies of the parallel component in the width direction of the cabinet, and the first power matrix module and the second power module are respectively connected to the parallel sheet metal assembly.

[0007] The high-power charging cabinet provided in this application embodiment has a parallel assembly fixed at the middle position of the cabinet width direction inside the cabinet body. The parallel assembly includes at least one pair of parallel copper busbar assemblies extending in the width direction of the cabinet body, at least one pair of parallel device assemblies corresponding to the at least one pair of parallel copper busbar assemblies, and a parallel sheet metal assembly. Thus, the first power matrix module and the second power matrix module can be fixed from both sides of the parallel assembly to each of the at least one pair of parallel copper busbar assemblies. Furthermore, the first power matrix module and the second power matrix module are further connected to the parallel sheet metal assembly. Therefore, the parallel assembly enables convenient installation and removal of the first power matrix module and the second power matrix module in the charging cabinet. Moreover, different specifications of power matrix modules can be selected as the first power matrix module and the second power matrix module according to actual needs, thereby realizing the free combination and matching of power matrix modules.

[0025] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0026] Electric vehicles typically rely on internal batteries to power their wheels, and their driving range depends on battery capacity. Therefore, as users' demands for longer driving ranges increase, battery capacities are growing, leading to an explosive increase in demand for high-power charging stations, such as those with a total output power exceeding 300kW. High-power charging stations generally consist of a charging cabinet and multiple charging terminals. The charging cabinet distributes high-power electricity from the external source to the charging terminals, allowing users to charge their electric vehicle's battery using the charging guns on the terminals. In this process, the power distribution components within the high-power charging cabinet are crucial for ensuring efficient charging for users.

[0027] In existing technologies, high-power charging cabinets are typically designed as a single unit. During installation, the power distribution components are installed one by one along with the other parts of the cabinet, following a set installation procedure. While the power distribution component has relatively independent functions, it forms a unified whole with the other cabinet components. During use, if the power distribution component malfunctions, the only solution is to disconnect the power to the entire charging cabinet for repair. Especially if a single component within the power distribution unit is damaged, it is necessary to disassemble the entire cabinet to repair or replace that damaged component. Furthermore, with the rapid development of charging technology, high-power charging technology undergoes frequent iterations, particularly in power distribution technology, a key component of charging cabinets. However, when new power distribution solutions are developed, the existing integrated installation of charging cabinets makes it difficult to replace only the power distribution components to incorporate the latest technology.

[0028] To address this, this application proposes a high-power charging cabinet that modularizes the power distribution components, ensuring that each component can be manufactured and prepared independently, allowing it to be either fully installed in or removed from the main cabinet. This modular design facilitates convenient and quick production, replacement, and maintenance.

[0029] For example, Figure 1 This is a structural schematic diagram of a high-power charging cabinet according to an embodiment of this application, as shown below. Figure 1 As shown, the high-power charging cabinet according to an embodiment of this application may include a cabinet body, a parallel component 3, a first power matrix module 1, and a second power matrix module 2. The parallel component 3, the first power matrix module 1, and the second power matrix module 2 can be housed within the cabinet body. In this embodiment, the parallel component 3 can be fixed inside the cabinet body and located at the middle position in the width direction of the cabinet body. The parallel component 3 may include at least one pair of parallel copper busbar assemblies, at least one pair of parallel device assemblies corresponding to the at least one pair of parallel copper busbar assemblies, and a parallel sheet metal assembly. Furthermore, in this embodiment, the parallel component 3 may also include multiple fasteners for connecting the parallel component 3 with the first power matrix module 1 and the second power matrix module 2. For example, during on-site installation, the parallel assembly 3 can be installed into the cabinet first, and then the first power matrix module 1 and the second power matrix module 2 can be fixed to the parallel assembly 3 with fasteners. In this way, if the first power matrix module 1 or the second power matrix module 2 fails and needs maintenance or upgrade in the future, the power matrix module that needs maintenance or upgrade can be removed from the parallel assembly 3 without disassembling other parts.

[0030] Figure 6 This is a schematic diagram of the structure of the parallel component according to an embodiment of this application. Figure 7 This is an exploded view of the structure of a parallel component according to an embodiment of this application. Figure 6 and Figure 7 As shown, each pair of parallel copper busbar assemblies 3-1 in the parallel assembly 3 may include parallel positive input copper busbar 3-1-1 and parallel negative input copper busbar 3-1-2 parallel to each other in the width direction of the cabinet, and a parallel device assembly 3-3 is provided at the middle position of the parallel positive input copper busbar 3-1-1 and parallel negative input copper busbar 3-1-2 in the width direction of the cabinet. For example, as Figure 7 As shown, the parallel component 3 may include four pairs of parallel copper busbar assemblies 3-1, and these four pairs of parallel copper busbar assemblies 3-1 may be evenly arranged from top to bottom at predetermined intervals along the height direction of the cabinet. Of course, in this embodiment, the spacing between the four pairs of parallel copper busbar assemblies 3-1 may also be different, and this application does not limit this. In addition, each pair of parallel copper busbar assemblies 3-1 may include a parallel positive input copper busbar 3-1-1 and a parallel negative input copper busbar 3-1-2, which are also arranged along the height direction of the cabinet. Figure 6 and Figure 7 In each pair of parallel copper busbar assemblies 3-1 shown, the parallel positive input copper busbar 3-1-1 is located above the parallel negative input copper busbar 3-1-2. However, in the embodiments of this application, the positional relationship between the parallel positive input copper busbar 3-1-1 and the parallel negative input copper busbar 3-1-2 is not limited to this. The parallel positive input copper busbar 3-1-1 may be located below the parallel negative input copper busbar 3-1-2.

[0031] Furthermore, the number of parallel copper busbar assemblies 3-1 in the parallel component 3 can be 3 pairs or less, or 5 pairs or more. This application does not limit this, and the number of parallel copper busbar assemblies 3-1 can be set according to the actual needs of use, as long as the parallel copper busbar assemblies 3-1 are configured in pairs, that is, including the parallel positive input copper busbar 3-1-1 and the parallel negative input copper busbar 3-1-2 configured in pairs.

[0032] Furthermore, the parallel sheet metal assembly 3-2 can be positioned at the top of the cabinet in the height direction of the parallel component 3, and can be fixed to the top of the cabinet. In addition, the parallel sheet metal assembly 3-2 can also be positioned at the middle of the cabinet in the width direction of the parallel component 3, that is, on the same straight line as the parallel device assembly 3-3. Of course, in the embodiments of this application, the parallel sheet metal assembly 3-2 can also be located on one side of the parallel device assembly 3-3, and this application does not limit this.

[0033] like Figure 7As shown, the parallel sheet metal assembly 3-2 includes: a parallel signal adapter board mounting plate 3-2-1 and multiple parallel fixing parts 3-2-2 corresponding to the two ends of the parallel positive input copper busbar 3-1-1 and the parallel negative input copper busbar 3-1-2 in each pair of parallel copper busbar assemblies 3-1. For example, the parallel fixing part 3-2-2 located on the side of the first power matrix module 1 can fix the corresponding parallel copper busbar assembly 3-1 to the first power matrix module 1, and the parallel fixing part 3-2-2 located on the side of the second power matrix module 2 can fix the corresponding parallel copper busbar assembly 3-1 to the second power matrix module 2.

[0034] like Figure 7 As shown, the parallel device assembly 3-3 may further include a DC contactor 3-3-1 to facilitate electrical contact with the DC contactors in the first power matrix module 1 and the second power matrix module 2. In embodiments of this application, the DC contactor 3-3-1 may correspond to each pair of parallel copper busbar assemblies 3-1. For example, as... Figure 7 As shown, the DC contactor 3-3-1 can have a paired structure arranged vertically to correspond one-to-one in spatial position with the paired parallel positive input copper busbar 3-1-1 and parallel negative input copper busbar 3-1-2 in the corresponding parallel copper busbar assembly 3-1. Each DC contactor 3-3-1 can be located at the end of each parallel copper busbar assembly 3-1 to facilitate electrical contact with the power matrix module on the corresponding side.

Figure 3 This is an exploded view of the power matrix module located on one side of the parallel components according to an embodiment of this application. Figure 4 This is a perspective view of the power matrix module located on the other side of the parallel components according to an embodiment of this application. Figure 5 This is an exploded view of the power matrix module located on the other side of the parallel component in an embodiment of this application. Figure 8 This is a schematic diagram of the internal structure of a high-power charging cabinet according to an embodiment of this application. Figures 2 to 5 As shown, the first power matrix module 1 and the second power matrix module 2 according to embodiments of this application can have similar structures. For example, the first power matrix module 1 may include a first matrix copper busbar assembly 1-1, a first matrix device assembly 1-3, and a first matrix sheet metal assembly 1-2, and the second power matrix module 2 may include a second matrix copper busbar assembly 2-2, a second matrix device assembly 2-3, and a second matrix sheet metal assembly 2-1. The first matrix copper busbar assembly 1-1 and the second matrix copper busbar assembly 2-2 can be fixedly connected from both sides of the parallel assembly 3 to the corresponding parallel copper busbar assembly 3-1 in the height direction of the cabinet. Figure 8 and Figure 3As shown, the first matrix device assembly 1-3 may include a first signal adapter board 1-3-1 and a first DC contactor 1-3-2, and the first matrix copper busbar assembly 1-1 may have a paired configuration, that is, each first matrix copper busbar assembly 1-1 may include two copper busbars parallel to each other in the width direction of the cabinet, for example, as Figure 3 As shown, the first matrix copper busbar assembly 1-1 may include a first matrix positive input copper busbar and a first matrix negative input copper busbar 1-1-1 to obtain power input by connecting to the parallel assembly 3. The first matrix sheet metal assembly 1-2 may include a first frame 1-2-1, a first upper cover plate 1-2-2, a first lower cover plate 1-2-3, and a first signal adapter board mounting plate 1-2-4. Therefore, the first frame 1-2-1 can provide support for the first matrix copper busbar assembly 1-1 and the first matrix device assembly 1-3, that is, the first matrix copper busbar assembly 1-1 can be fixed to the first frame 1-2-1, and the first matrix copper busbar assembly 1-1 can further extend beyond the first frame 1-2-1 to the side opposite to the second power matrix module 2, that is, away from the second power matrix module 2, on the side away from the parallel assembly 3. In addition, the first matrix copper busbar assembly 1-1 may also extend to the second power matrix module 2 by a predetermined length beyond the side of the first frame 1-2-1 near the parallel component 3, so as to connect to the parallel copper busbar assembly 3-1 of the parallel component 3 through the matrix copper busbar assembly that extends beyond the side of the first frame 1-2-1 near the parallel component 3. The first upper cover plate 1-2-2 and the first lower cover plate 1-2-3 in the first matrix sheet metal assembly 1-2 can respectively cover the upper and lower halves of the side of the frame 1-2-1 in the height direction of the cabinet. Thus, the first matrix copper busbar assembly 1-1 set inside the first frame 1-2-1 can be covered by these two cover plates 1-2-2 and the first cover plate 1-2-3. The first signal adapter board mounting plate 1-2-4 can be set on the top of the first frame 1-2-1. The first signal adapter board 1-3-1 of the first matrix device assembly 1-3 can be fixed to the first signal adapter board mounting plate 1-2-4 by, for example, combination screws. The first matrix positive input copper busbar and the first matrix negative input copper busbar of the first matrix copper busbar assembly 1-1 can be respectively fixedly connected to the parallel positive input copper busbar 3-1-1 and the parallel negative input copper busbar 3-1-2 in a pair of parallel copper busbar assemblies 3-1. The first matrix copper busbar assembly 1-1 can also include multi-path matrix output copper busbars. For example, Figure 3 As shown, the first matrix copper busbar assembly 1-1 may include one positive output copper busbar 1-1-2, one negative output copper busbar 1-1-3, two positive output copper busbars 1-1-4, and two negative output copper busbars 1-1-5. These multi-output copper busbars can be parallel to each other and can be arranged in pairs at different heights along the height direction of the cabinet. For example, as... Figure 3 As shown, one positive output copper busbar 1-1-2 and one negative output copper busbar 1-1-3 can be positioned in the middle of the first matrix copper busbar assembly 1-1, while two positive output copper busbars 1-1-4 and two negative output copper busbars 1-1-5 can be positioned at the bottom of the first matrix copper busbar assembly 1-1. Furthermore, these multi-output copper busbars can extend perpendicularly to each other with respect to the input copper busbars; that is, these multi-output copper busbars can be parallel to each other and extend perpendicularly to the input copper busbars, such as the first matrix positive input copper busbar and the first matrix negative input copper busbar. Therefore, as described above, the first matrix positive input copper busbar and the first matrix negative input copper busbar can extend in the width direction of the cabinet, while each output copper busbar can extend in the height direction of the cabinet.

[0036] In the embodiments of this application, such as Figure 8 and Figure 5 As shown, the second power matrix module 2 may include a second matrix copper busbar assembly 2-2, a second matrix device assembly 2-3, and a second matrix sheet metal assembly 2-1. The first matrix copper busbar assembly 1-1 and the second matrix copper busbar assembly 2-2 can be fixedly connected from both sides of the parallel assembly 3 to the corresponding parallel copper busbar assembly 3-1 in the height direction of the cabinet. The second matrix device assembly 2-3 may include a second signal adapter board 2-3-1 and a second DC contactor 2-3-2, and the second matrix copper busbar assembly 2-2 may have a paired configuration, i.e., each second matrix copper busbar assembly 2-2 may include two copper busbars parallel to each other in the width direction of the cabinet, for example, as... Figure 5As shown, the second matrix copper busbar assembly 2-2 may include a second matrix positive input copper busbar and a second matrix negative input copper busbar 2-2-1 to obtain power input by connecting to the parallel assembly 3. The second matrix sheet metal assembly 2-1 may include a second frame 2-1-1, a second upper cover plate 2-1-2, a second lower cover plate 2-1-3, and a second signal adapter board mounting plate 2-1-4. Therefore, the second frame 2-1-1 can provide support for the second matrix copper busbar assembly 2-2 and the second matrix device assembly 2-3, that is, the second matrix copper busbar assembly 2-2 can be fixed to the second frame 2-1-1, and the second matrix copper busbar assembly 2-2 can further extend beyond the second frame 2-1-1 to the side opposite to the first power matrix module 1, that is, away from the first power matrix module 1, on the side away from the parallel assembly 3. Furthermore, the second matrix copper busbar assembly 2-2 can also extend a predetermined length toward the first power matrix module 1 beyond the side of the second frame 2-1-1 near the parallel component 3, so as to connect to the parallel copper busbar assembly 3-1 of the parallel component 3 via this extended matrix copper busbar assembly near the parallel component 3 of the second frame 2-1-1. The second upper cover plate 2-1-2 and the second lower cover plate 2-1-3 in the second matrix sheet metal assembly 2-1 can respectively cover the upper and lower halves of the side of the second frame 2-1-1 in the height direction of the cabinet, so that the second matrix copper busbar assembly 2-2 disposed inside the second frame 2-1-1 can be concealed by these two cover plates, and the second signal adapter plate 2-1-4 can be disposed on the top of the second frame 2-1-1, and the second signal adapter plate 2-3-1 of the second matrix device assembly 2-3 can be fixed to the second signal adapter plate 2-1-4 by, for example, combination screws. The second matrix copper busbar assembly 2-2 can have its second matrix positive input copper busbar and second matrix negative input copper busbar fixedly connected to the parallel positive input copper busbar 3-1-1 and parallel negative input copper busbar 3-1-2 in a pair of parallel copper busbar assemblies 3-1, respectively. The second matrix copper busbar assembly 2-2 can also include multi-channel matrix output copper busbars. For example... Figure 5 As shown, the second matrix copper busbar assembly 2-2 may include one positive output copper busbar 1-1-2, one negative output copper busbar 1-1-3, two positive output copper busbars 1-1-4, and two negative output copper busbars 1-1-5. These multi-output copper busbars can be parallel to each other and can be arranged in pairs at different heights along the height direction of the cabinet. For example, as... Figure 5As shown, one positive output copper busbar 1-1-2 and one negative output copper busbar 1-1-3 can be positioned in the middle of the second matrix copper busbar assembly 2-2, while two positive output copper busbars 1-1-4 and two negative output copper busbars 1-1-5 can be positioned at the bottom of the second matrix copper busbar assembly 2-2. Furthermore, these multi-output copper busbars can extend perpendicularly to each other with respect to the input copper busbars; that is, these multi-output copper busbars can be parallel to each other and extend perpendicularly to the input copper busbars, such as the second matrix positive input copper busbar and the second matrix negative input copper busbar. Therefore, as described above, the second matrix positive input copper busbar and the second matrix negative input copper busbar can extend in the width direction of the cabinet, while each output copper busbar can extend in the height direction of the cabinet.

[0037] also, Figure 9a This is a schematic diagram of the first signal adapter board according to an embodiment of this application. Figure 9b This is a schematic diagram of the second signal adapter board according to an embodiment of this application. Figure 10 This is a schematic diagram of the installation of the signal adapter board mounting plate for the parallel components according to an embodiment of this application. Figure 9a As shown, the first signal adapter board mounting plate 1-2-4 in the first power matrix module 1 is inserted into the first power matrix module 1, thereby fixing the first signal adapter board mounting plate 1-2-4 to the parallel signal adapter board mounting plate 3-2-1. Figure 9b As shown, the second signal adapter board mounting plate 2-1-4 in the second power matrix module 2 can be connected to the second signal adapter board 2-3-1 by combination screws 1-2-5, so that the second signal adapter board mounting plate 2-1-4 can be inserted into the second power matrix module 2.

[0038] Furthermore, in this embodiment, the number of the first input copper busbar in the first power matrix module 1 and the number of the second input copper busbar in the second power matrix module 2 can be set according to actual usage needs. Figure 11 This is a schematic diagram of a first combination of power matrix modules according to an embodiment of this application; Figure 12 This is a schematic diagram of a second combination of power matrix modules according to an embodiment of this application; Figure 13 This is a schematic diagram of a third combination of power matrix modules according to an embodiment of this application. Figures 11 to 13As shown, for example, the number of the first or second input copper busbars can be set to four groups, and the number of output copper busbars can be two groups. Therefore, the module component includes a total of 8 inputs (1 input DC+, DC- to 8 input DC+, DC-) and can achieve 4 supercharging outputs (1 supercharging output DC+, DC- to 4 supercharging outputs DC+, DC-). Each supercharging output can guarantee a rated current output of 500A, with a maximum of 650A. Of course, in other embodiments, the number of the first or second input copper busbars can be set to four groups, and the number of output copper busbars can be four groups. The module component includes a total of 8 inputs (1 input DC+, DC- to 8 input DC+, DC-) and can achieve 8 fast charging outputs (1 fast charging output DC+, DC- to 4 fast charging outputs DC+, DC-). Each fast charging output can guarantee a rated current output of 300A, with a maximum of 400A. In addition, the number of the first or second input copper busbars can be set to four groups, and the number of output copper busbars can be set to four groups. The module component includes a total of 8 inputs (1 input DC+, DC- to 8 input DC+, DC-), and can realize 6 fast charging outputs (1 fast charging output DC+, DC- to 3 fast charging outputs DC+, DC-, 5 fast charging outputs DC+, DC- to 7 fast charging outputs DC+, DC-) + 2 supercharging outputs (4 supercharging outputs DC+, DC- and 8 fast supercharging outputs DC+, DC-). A single fast charging channel can guarantee a rated current output of 300A and a maximum current output of 400A. A single supercharging channel can guarantee a rated current output of 500A and a maximum current output of 650A.

[0039] Therefore, in this embodiment, the number of input copper busbars and the number of output copper busbars in the first power matrix module 1 and the second power matrix module 2 located on both sides of the parallel component 3 can be configured separately to achieve various combinations of power matrix modules. For example, the first power matrix module 1 and the second power matrix module 2 together include 8 inputs and can achieve 4 fast charging outputs + 2 supercharging outputs. A single fast charging output can guarantee a rated current output of 300A and a maximum current output of 400A, while a single supercharging output can guarantee a rated current output of 500A and a maximum current output of 650A. Alternatively, the first power matrix module 1 and the second power matrix module 2 together can include 8 inputs and can achieve 7 fast charging outputs + 1 supercharging output. A single fast charging output can guarantee a rated current output of 300A and a maximum current output of 400A, while a single supercharging output can guarantee a rated current output of 500A and a maximum current output of 650A. Furthermore, the first power matrix module 1 and the second power matrix module 2 together include 8 inputs and can achieve 3 fast charging outputs and 3 supercharging outputs, for a total of 6 outputs. A single fast charging output can guarantee a rated current output of 300A and a maximum current output of 400A, while a single supercharging output can guarantee a rated current output of 500A and a maximum current output of 650A.

[0040] The high-power charging cabinet provided in this application embodiment has a parallel assembly fixed at the middle position of the cabinet width direction inside the cabinet body. The parallel assembly includes at least one pair of parallel copper busbar assemblies extending in the width direction of the cabinet body, at least one pair of parallel device assemblies corresponding to the at least one pair of parallel copper busbar assemblies, and a parallel sheet metal assembly. Thus, the first power matrix module and the second power matrix module can be fixed from both sides of the parallel assembly to each of the at least one pair of parallel copper busbar assemblies. Furthermore, the first power matrix module and the second power matrix module are further connected to the parallel sheet metal assembly. Therefore, the parallel assembly enables convenient installation and removal of the first power matrix module and the second power matrix module in the charging cabinet. Moreover, different specifications of power matrix modules can be selected as the first power matrix module and the second power matrix module according to actual needs, thereby realizing the free combination and matching of power matrix modules.
