Design and Implementation of a Hybrid Micro- Power Energy Ecosystem for Automatic EV Charging Station

Abstract: With the rapid growth of electric vehicles (EVs), the demand for safe, efficient, and user- friendly charging infrastructure has become a major challenge. Conventional plug-in charging systems often face issues such as cable wear, electrical hazards, and lack of automation. To address these limitations, this study proposes a fully automated wireless EV charging system that enhances both safety and convenience. The system uses an Arduino Nano as the central controller, integrating an RFID module for user authentication, a relay for controlled power switching, and a buck converter for voltage regulation. Once an authorized user is detected through RFID, the system automatically initiates wireless charging and continuously monitors parameters such as voltage, current, and time through a serial interface for cost estimation. The proposed design eliminates manual intervention, minimizes connection-related risks, and provides a reliable and low-cost solution for modern EV charging applications. This automated system demonstrates a smart approach to developing safer and more accessible EV infrastructure.
