Charging piles are gas stations for electric vehicles. According to the types and styles of charging piles, they can be fixed on the ground and walls and installed in public places, residential areas, charging stations and other places. Charging for various types of electric vehicles according to different voltage levels, charging piles are divided into two different ways: conventional charging and fast charging. The charging pile display screen can realize timing, electricity counting and amount charging, which is very simple and convenient to use, the charging data can be read through the charging pile display screen, which is very clear and clear. There are many types of charging piles, which are divided into floor-mounted charging piles and wall-mounted charging piles according to installation methods. According to the installation location, it is divided into public charging piles and special charging piles. According to the number of charging interfaces, it is divided into one single charging pile and one multi-charging pile to improve the efficiency and practicability of public charging piles. According to the charging method, it is divided into DC charging pile, AC charging pile and AC/DC. In the early stage of charging pile design, designers need to conduct sufficient market research to find the advantages and disadvantages of products, combine the design needs of users, research data and inspiration, and carry out R & D and innovation from different angles such as appearance design, structural design, mold opening, material selection, man-machine operation, etc. The function of the wall-mounted charging pile conforms to the national industry standards. The charging pile is efficient and energy-saving, stable in performance, and has a high level of safety protection. It supports a variety of payment methods during use and provides users with convenient charging services. The appearance design is light and simple, the color adopts classic black collocation, the surface process is exquisite, and the texture is exquisite; pay attention to the details, the height of the human-computer interaction interface is reasonable, and the operation is simple and convenient; it supports wall-mounted installation and vertical column installation, which can be based on the installation Position and environment for reasonable configuration and installation; the charging pile is equipped with an emergency stop switch, which can be urgently stopped in case; charging piles also have protection functions such as overvoltage, undervoltage, abnormal charging, overload, short circuit, overheating, etc. The protection level can reach IP54 with high safety factor. Rugged and durable, adapted to different environments, and can meet various installation conditions and use requirements.
