Wireless Charging of Battery in Electric Vehicle

Abstract: This paper presents a new IoT-integrated wireless charging system designed for electric vehicles (EVs) that features an automated mechanical lifting system to adjust the alignment of the two coils. The innovation involved in the study is to create a wireless inductive charging system using a threaded screw-rod vertical movement to raise the transmitter coil mounted in the ground until it meets the receiver coil located underneath the EV chassis. This design reduces the distance between the coils and maximizes energy transfer efficiency. Users control the system via a mobile IoT app to automate the lifting and charging processes and improve ease of use. The system also integrates an independent IoT-enabled Battery Management System (BMS) that monitors battery temperature and smoke level and alerts the user if any overheating or dangerous conditions are detected. The proposed system can be adopted in public or commercial parking locations such as malls, hotels and theatres. Future work involves linking a system for using renewable solar energy by converting the solar DC to AC for wireless transmission, thus facilitating the use of sustainable green energy.
