Design and Research of an Automatic Charging System for Electric Vehicles

An automatic charging system is designed to connect the charging pile and the electric vehicle in this paper. The system includes three subsystems: the charging hole positioning subsystem, the automatic charging execution subsystem, the communication / control subsystem. After receiving the charging command, the system can select the nearest idle charging pile, move the charging gun according to the path, find and locate the charging hole of the vehicle, so as to realize automatic charging. After charging, the charging gun can be put back in place according to the path and wait for the next charging command. The system adopts the combination of approximate positioning and precise positioning, and the combination of overall movement and precise control. It can not only make multiple electric vehicles share charging piles, but multiple charging piles share the automatic charging system. In addition, compared with the mobile robot moving in any direction, the cost is greatly reduced.
