Research and Design of Electric Vehicle Charging Pile Control System

Abstract

The charging pile is the main equipment for electric vehicle charging station, which can charge power for various types of electric vehicles. According to the different voltage grade, each charging pile is equipped with a recharge control system. The charging pile of electric vehicle can use AC, DC power to supply, which needs a special electric vehicle’s charging card and by using the RFID card and charging the battery pack. The charging pile display is able to show some parameters and data, such as charging voltage, charging current, charging amount, recharge expense, charging time, and so on. This paper gives the research and design of the charging pile control system, which are used to recharge for electric vehicles in the residential area. It can show the charging status that provided by the man-machine interactive hardware and interface, which can realize the charging monitor and charging electric measurement, and can display or print out the electricity consumption, cost, and battery parameters.
