[0016] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-3The present invention provides a technical solution: an AC / DC integrated charging pile, including a shell 1, with AC charging port 4 and DC charging port 5 respectively opened on the two side walls of the shell 1, and charging guns are respectively plugged into the AC charging port 4 and DC charging port 5, and a cable is connected to the tail of the charging gun. The charging pile is used to realize AC / DC integrated dual-gun charging.

[0018] The top of the outer casing 1 is provided with a top plate 2, which is inclined on the back of the outer casing 1, and the inclination angle α of the top plate 2 is preferably 5°. The outer casing 1 adopts an IP54 high-efficiency protection level design, which has dustproof and waterproof splashproof capabilities. The inclined setting of the top plate 2 is used to prevent rainwater from staying on the top of the charging pile. Therefore, it has strong environmental adaptability, can adapt to harsh weather, and improves the safety and stability of the charging pile.

[0019] The bottom of the outer casing 1 is fixedly connected to a base 3. The base 3 has a hollow structure inside, and perforations are opened on both sides of the base 3. The inside of the base 3 is used for cable arrangement, and the perforations are used for the cable to pass through on the same side. This effectively utilizes the space inside the pile and realizes concealed wiring, separating the dual-gun cable from the communication cable and avoiding electromagnetic interference. The base 3 is usually supported and fixed at the required installation position by a threaded connection, which makes the installation process simple and reduces construction costs.

[0020] The housing 1 has a vertically mounted mounting plate inside. An AC / DC isolation module 8 is located in the upper part of the mounting plate, a charging control module 7 is located on one side of the middle part of the mounting plate, and a communication module 9 is located below the charging control module 7. The AC / DC isolation module 8, the charging control module 7, and the communication module 9 are all connected to the mounting plate. The charging control module 7 supports remote OTA upgrades and fault diagnosis, improving operation and maintenance efficiency. The charging control module 7 integrates an AC charging control board and a DC charging control board. The AC charging control board controls the entire charging process and safety management, and outputs AC charging commands. The DC charging control board controls the AC-DC conversion to output DC charging commands. The charging control module 7 supports and manages AC and DC dual-gun charging through different interfaces and protocols, and the two guns can work simultaneously. The charging control module 7 integrates AC slow charging and DC fast charging functions, which reduces material and production costs, and also greatly reduces the space occupied in the charging pile. In addition, it can intelligently distribute power. It should be noted that the AC charging control board is preferably a 7kW AC control board that conforms to national standards, and the DC charging control board is preferably a 60kW DC fast charging control board that conforms to national standards. The AC / DC isolation module 8 is built on a unified DC bus to construct a power pool. It uses a controller to isolate the AC charging control board from the DC charging control board, ensuring the safety of AC and DC charging and supporting peak and valley electricity price response and orderly charging. The communication module 9 supports 4G / 5G and NB-IoT multi-mode communication, and by default prioritizes connecting to the 5G network to obtain the best bandwidth and low latency. When the 5G signal coverage is poor, it can automatically switch to the 4G network as a high-performance supplement. At the same time, it integrates the NB-IoT standard, which is specifically used to stably upload and operate data in remote areas or areas with weak signals.

[0021] Each of the two side walls of the outer casing 1 is hinged with a side plate. A heat dissipation module 10 is installed on one of the side plates for heat dissipation inside the pile. The heat dissipation module 10 includes several cooling fans. The cooling fans are evenly distributed on the surface of the side plate. The cooling fans are electrically connected to a fan control board, which is also installed on the same side plate, thereby controlling the operation of the cooling fans. The housing 1 also includes multiple DC fast charging modules 11 and AC charging modules 12. The multiple DC fast charging modules 11 are designed in parallel. The multiple DC fast charging modules 11 are used to convert AC power into DC power and receive instructions from the DC charging control board to adjust the output current and voltage. The AC charging modules 12 are connected to the AC charging control board and are used to transmit AC power through AC contactors.

[0022] An interactive module 6 is installed on the front panel of the outer casing 1. The interactive module 6 is connected to the AC charging control board for signal transmission and is used to perform human-computer interaction and external communication, thereby improving the intelligent setup of the charging pile.

[0023] In this embodiment, the charging modes include: ① When the charging pile gives only an AC charging command, the AC charging control board starts working, the DC charging module stops working, and AC charging begins; ② When the charging pile gives only a DC charging command, the DC charging module works, the AC charging control board stops working, and DC charging begins; ③ When the charging pile gives both AC and DC charging commands, both the AC charging control board and the DC charging control board start working, enabling the charging pile to perform both AC and DC charging simultaneously, achieving simultaneous operation of both charging guns.

[0024] It should be noted that when this charging pile is deployed at a public charging station in a certain city, the system automatically shuts down the power of the AC charging module 12 when the user plugs in the DC charging gun, prioritizing DC fast charging; when deployed in remote towns and villages where there is no stable 4G signal, NB-IoT low-power communication is enabled, and data is only uploaded at the beginning and end of charging.

[0025] The charging pile in this solution integrates AC and DC functions, saving more than 30% of the floor space and improving space utilization. In addition, it uses high-efficiency protective materials, which can effectively resist severe weather. In summary, this charging pile, which integrates structure, power sharing, intelligent scheduling, and environmental protection, is not only suitable for various scenarios such as urban public charging stations, residential communities, towns, and remote areas, but also for charging scenarios that require efficient use of space and power resources.
