Community charging pile refers to the charging equipment that provides charging services for electric vehicles. The charging pile (bolt) can realize timing, metering, and charging. plug) efficiency and practicality. Community charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile manufacturer ranking to carry out the corresponding charging method, charging time, and cost. For data printing and other operations, the display screen of the charging pile can display data such as charging amount, cost, and time of the new energy charging pile manufacturer. The input end of the community charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug, which is used as a power grid. The special structure of the electric vehicle community charging pile (bolt) on the electric side determines that the characteristics of the automatic communication system are many and scattered measured points, wide coverage and short communication distance. (1) Communication reliability——The communication system must withstand the test of the harsh environment of the car charging pile manufacturer and strong electromagnetic interference or noise interference for a long time, and keep the communication smooth. (2) Construction costs——Under the premise of satisfying the reliability, the construction cost of the car charging pile and the cost of long-term use and maintenance should be considered comprehensively. (3) Two-way communication——Not only can upload the amount of information, but also realize the release of the amount of control. (4) Multi-service data transmission speed pure electric vehicle charging pile rate——With the continuous growth of the terminal business volume in the future, the communication between the main station and the sub-station, and the sub-station to the terminal requires higher and higher data transmission rates to realize multi-service. Charging pile is a terminal device that uses charging pile solutions to charge new energy electric vehicles. A charging pile is an electric vehicle charging station, a terminal device used for charging new energy electric vehicles, and an essential supporting facility for the rapid development of new energy electric vehicle charging pile OEMs. The shape of the charging pile is like a parking chronograph. The design of the charging pile can realize timing, metering, and charging. The rapid development of new energy electric charging pile customized cars requires the rapid development and popularization of charging piles as a basis. There are three types of AC charging piles, DC charging piles, and AC-DC integrated charging piles. DC charging piles are generally installed on highways, charging stations and other places with ODM charging piles. AC charging piles are generally installed in residential areas, parking lots, road parking spaces, expressway service areas, etc. Due to the different environments where charging piles are installed, in addition to structural design, appearance design, market research, production costs, and materials, designers also need to Fully consider the environmental factors, according to the use environment of the charging pile, carry out the corresponding protection design, charging pile OEM.
