Abstract: This paper presents a novel smart wireless electric vehicle (EV) charging station that integrates solar photovoltaic (PV) and piezoelectric road-energy harvesting with a smart-grid-connected common DC bus architecture. The proposed system employs bidirectional Wireless Power Transfer (WPT) for Grid-to-Vehicle (G2V) and Vehicle-to-Grid (V2G) operation and an intelligent Energy Management System (EMS) for real-time power optimization. Maximum Power Point Tracking (MPPT), adaptive load balancing, and predictive renewable forecasting enhance overall energy efficiency. Advanced coil-alignment sensors enable high coupling efficiency, while a bidirectional DC/AC interface ensures stable grid interaction. The system aims to provide eco-friendly, contactless, and efficient EV charging suitable for smart cities, highways, and autonomous transportation networks.
