Description

Technical Field

[0001] This utility model relates to the field of charging power supplies, and in particular to an integrated charging power supply. Background Technology

[0002] With the rapid development of electric vehicles and the expansion of the electric vehicle market, the demand for charging is also increasing. Currently, electric vehicles are usually charged by using charging stations to connect to the municipal power grid. However, these charging stations are fixed on the ground, and because they are connected to the power grid, their location cannot be moved, which makes scheduling inconvenient. Furthermore, the installation of charging stations requires the separate installation of transformers, and then the laying of cables to connect the transformers to each charging station. The installation process is complex, occupies a large area, and is also inconvenient for scheduling.

[0003] Therefore, the technology needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated charging power supply that addresses the aforementioned problems, integrates multiple modules, simplifies installation, and effectively reduces the footprint and scheduling difficulty.

[0005] The technical solution adopted by this utility model is as follows: an integrated charging power supply, including a main frame, which is divided into three chambers, namely a high-voltage chamber, a low-voltage charging pile chamber, and a transformer chamber. A high-voltage switch cabinet is installed in the high-voltage chamber, a low-voltage charging module is installed in the low-voltage chamber, and a transformer is installed in the transformer chamber. The incoming end of the high-voltage switch cabinet has a high-voltage connector for connecting to the power grid. The outgoing end of the high-voltage switch cabinet is connected to the high-voltage side of the transformer. The low-voltage side of the transformer is connected to the incoming end of the low-voltage charging module. Multiple charging guns are connected to the outgoing end of the low-voltage charging module.

[0006] Furthermore, the low-voltage charging pile chamber is located between the high-voltage chamber and the transformer chamber.

[0007] Furthermore, the multiple charging guns are evenly arranged on the main frame on both sides of the low-voltage charging stack chamber.

[0008] Furthermore, the low-voltage charging module includes at least an input line unit, a capacitor compensation module, and multiple charging units. The output terminal of the transformer is connected to the input terminal of the input line unit, and the input terminals of the capacitor compensation module and the multiple charging units are connected in parallel to the output terminal of the input line unit.

[0009] Furthermore, the charging unit includes a charging switch module and a charging module. The input terminals of all charging switch modules are connected in parallel to the output terminals of the input unit. The output terminal of each charging switch module is connected to the input terminal of the charging module. The output terminals of all charging modules are connected in parallel to the charging busbar. Multiple charging guns are connected in parallel to the charging busbar.

[0010] Furthermore, it also includes multiple output units, which are connected in parallel to the output terminals of the input terminal unit.

[0011] Furthermore, the low-voltage charging pile chamber has an upper space, a middle space, and a lower space. The capacitor compensation module and the charging module are installed in the upper space, the charging switch module, the output unit, and the incoming line unit are installed in the middle space, and the connecting busbar connecting the transformer and the high-voltage switchgear is arranged in the lower space.

[0012] Furthermore, the three-dimensional frame is also covered with cabinet panels.

[0013] Furthermore, the cabinet panel is provided with an air inlet and an air outlet, both of which are dustproof air vents.

[0014] Furthermore, for the high-voltage chamber and the transformer chamber, the air inlet is located near the bottom of the three-dimensional frame, and the air outlet is located at the top of the three-dimensional frame; or / and for the low-voltage charging pile chamber, the air inlet is located on the entire front panel, and the air outlet is located near the top of the three-dimensional frame.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This utility model integrates the transformer, low-voltage charging module, and high-voltage switchgear into the main frame, achieving multi-module integration and effectively reducing the footprint. At the same time, when connecting to the power grid, only the high-voltage switchgear needs to be connected to the power grid, without the need for excessive wiring operations, which is convenient for installation. Furthermore, since all components are integrated into the main frame, the connection between the high-voltage switchgear and the power grid can be disconnected during dispatching, and the entire unit can then be transported to its destination, which is convenient for dispatching.

Detailed Implementation

[0017] In the description of this specification, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing this specification and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this specification.

[0018] Furthermore, the use of terms such as "horizontal" or "vertical" in this specification does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0019] In the description of this specification, it should also be noted that, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” should be interpreted broadly. For example, a link can be a fixed link, a detachable link, or an integral link; it can be a mechanical link or an electrical link; it can be a direct link or an indirect link through an intermediate medium; it can be a connection within two components.

[0020] Example 1 like Figures 1-4 As shown, the integrated charging power supply includes a main frame 1, which is divided into three chambers: a high-voltage chamber 11, a low-voltage charging pile chamber 12, and a transformer chamber 13. A high-voltage switchgear is installed in the high-voltage chamber 11, a low-voltage charging module is installed in the low-voltage chamber, and a transformer 3 is installed in the transformer chamber 13. The high-voltage switchgear 2 has a high-voltage connector for connecting to the power grid at its inlet. The outlet of the high-voltage switchgear 2 is connected to the inlet of the transformer 3, and the outlet of the transformer 3 is connected to the inlet of the low-voltage charging module. Four charging guns 8 are connected to the outlet of the low-voltage charging module, and the charging guns are located on the central column of the housing.

[0021] In this embodiment, both the high-voltage switchgear 2 and the transformer 3 are conventional electrical devices in the art, and their specific structures will not be described in detail in this embodiment.

[0022] In this embodiment, after the incoming terminal of the high-voltage switchgear 2 is connected to the power grid, the voltage in the power grid enters the transformer 3 through the high-voltage switchgear 2. The transformer 3 converts the high-voltage electrical energy into low-voltage low-energy. The low-voltage electrical energy is input to the low-voltage charging module through the incoming terminal. The low-voltage charging module converts the AC power into DC power and supplies it to the charging gun 8. The vehicle can then be connected to the charging gun 8 for charging.

[0023] In this embodiment, the transformer 3, the low-voltage charging module 62, and the high-voltage switchgear 2 are integrated into the main frame 1, realizing multi-module integration and effectively reducing the footprint. At the same time, when connecting to the power grid, only the high-voltage switchgear 2 needs to be connected to the power grid, without the need for excessive wiring operations, which is convenient for installation. Furthermore, since they are all integrated into the main frame 1, the connection between the high-voltage switchgear 2 and the power grid can be disconnected during dispatching, and then the whole unit can be transported to the destination, which is convenient for dispatching.

[0024] Example 2 Based on Example 1, further feasible implementation methods are proposed.

[0025] In one feasible implementation, the low-voltage charging pile chamber 12 is located between the high-voltage chamber 11 and the transformer chamber 13, so that the area directly opposite the high-voltage chamber 11 and the low-voltage chamber can be used as a parking area for trams, reducing space waste.

[0026] In one feasible implementation, multiple charging guns 8 are evenly arranged on the main frame 1 on both sides of the low-voltage charging pile chamber 12. Specifically, there are four charging guns 8, with two charging guns 8 arranged on the front and two on the back of the main frame 1 respectively; the charging guns 8 on the same side are located at both ends of the main frame 1 where the low-voltage charging pile chamber 12 is located; that is, the charging guns are located on the middle column of the enclosure.

[0027] In one feasible implementation, the low-voltage charging module includes at least an input line unit 4, a capacitor replenishment module 5, and multiple charging units 6. The output terminal of the transformer 3 is connected to the input terminal of the input line unit 4, and the input terminals of the capacitor replenishment module 5 and the multiple charging units 6 are connected in parallel to the output terminal of the input line unit 4. Specifically, after the high-voltage electrical energy is converted into low-voltage electrical energy by the transformer 3, the low-voltage electrical energy enters the multiple charging units 6 after passing through the input line unit 4. The capacitor replenishment module 5 helps to stabilize the electrical energy.

[0028] Furthermore, the charging unit 6 includes a charging switch module 61 and a charging module 62. The input terminals of all charging switch modules 61 are connected in parallel to the output terminals of the input unit 4. The output terminal of each charging switch module 61 is connected to the input terminal of the charging module 62. The output terminals of all charging modules 62 are connected in parallel to the charging busbar 63. Multiple charging guns 8 are connected in parallel to the charging busbar 63. The electrical energy from the input unit 4 is converted from AC to DC in the charging module 62 through the charging switch module 61 to provide DC power to the charging guns 8.

[0029] Furthermore, it also includes multiple output units 7, which are connected in parallel to the output terminals of the input terminal. The output units 7 output AC power, which can be used to connect other external charging devices.

[0030] In one feasible implementation, the low-voltage charging pile chamber 12 has an upper layer 122 space, a middle layer 123 space, and a lower layer 121 space. The capacitor replenishment module 5 and the charging module 62 are installed in the upper layer 122 space, the charging switch module 61, the output unit 7, and the input line unit 4 are installed in the middle layer 123 space, and the connecting busbar connecting the transformer 3 and the high-voltage switch cabinet 2 is arranged in the lower layer 121 space. This vertical arrangement reduces the area occupied.

[0031] One feasible implementation method involves covering the three-dimensional frame with cabinet panels, which serve a protective function.

[0032] In one feasible implementation, the cabinet panel is provided with an air inlet 91 and an air outlet 92. Both the air inlet 91 and the air outlet 92 are dustproof air outlets, which can not only achieve heat dissipation, but also reduce the entry of dust into the high-voltage chamber 11, the low-voltage charging pile chamber 12 and the transformer chamber 13, thereby reducing the risk of fire caused by static electricity caused by dust.

[0033] Furthermore, dustproof air vents are a conventional structure in this field, and their specific structure will not be described in detail; of course, dustproof air vents can also be dustproof metal mesh.

[0034] In one feasible implementation, for the high-voltage chamber 11 and the transformer chamber 13, the air inlet 91 is located near the bottom of the three-dimensional frame, and the air outlet 92 is located at the top of the three-dimensional frame; or / and for the low-voltage charging pile chamber 12, the air inlet 91 is located on the entire front panel, and the air outlet 92 is located near the top of the three-dimensional frame, which can effectively improve the heat dissipation effect.

[0035] In one feasible implementation, the output terminal of the low-voltage charging module is also connected to a display port, which is connected to a display screen 10 with a controller for acquiring and displaying power consumption information.

[0036] One feasible implementation also includes an antenna box 101, which is signal-connected to the controller for transmitting power consumption information to the mobile terminal.

[0037] It should be noted that the software and electrical technologies for the controller to acquire power consumption information and transmit the power consumption information to the mobile terminal through the antenna box 101, and to display the power consumption information on the display screen 10, are well known to those skilled in the art. The present specification only makes structural improvements and does not need to be described in detail in this specification.

[0038] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
