Charging piles are divided into column type charging pile, floor type charging pile design and wall-mounted charging pile design according to the style. According to the charging gun, it is divided into single gun charging pile design and double gun charging pile design. According to the charging mode, it is divided into: DC charging pile, AC charging pile and AC DC integrated charging pile design. There are many kinds of charging piles, and different division standards have different design standards. Electronic design is an important content in the process of charging pile development and production, and is the key to realize the function of charging pile. Reasonable electronic design can guarantee the normal operation and use of the product, improve the efficiency and life of the product, and save resources and production costs. The design of electronic charging pile needs to have strong safety, reliability, perfect fault exception protection function, and can flexibly support different function expansion. The electronic charging pile needs to have the most basic charging function, strong compatibility, support automatic charging and manual charging, and meet various modes of AC charging; it has the functions of charging according to time, charging according to power, charging according to appointment time, and automatic charging; with output Detection, ic card detection, metering detection, emergency stop detection, network detection, switch value and other input information detection, running status detection, and fault detection functions; the design is simple human-computer interaction function, equipped with 4.3, 5.7, 7.0, 8.0 and 10.0 inch touch screens, which is convenient to operate and use. The charging pile has the function of scanning and paying by two-dimensional code mobile phone and is equipped with IC card reader, which can pay by credit card at the same time.
