Movable Wireless Charging System for Multiple Electric Vehicles

Abstract

This paper discusses the design of wireless induction charging and radar to identify power receiving place, image identification, and adjustment position for vehicles. The research idea came from EVs as well as the increasingly mature wireless charging technology in recent years. This paper analyzes the possibility of using the radar system combined with image recognition to solve the problems when vehicles are currently charged at fixed positions. Vehicles sometimes cannot be accurately aligned with the power transmission board, resulting in poor efficiency, or there is insufficient power transmission board due to locations. This paper provides solutions to improve charging efficiency, using radar as a sensor in design to find the position of the vehicle and position it below the power receiving place. The image recognition module PIXY 2 is also employed to capture the image color to adjust a more accurate position, so that the charging efficiency and speed can be improved and that time and space limitation can be avoided.
