The increasing demand for sustainable transportation has accelerated research into innovative charging methods for electric vehicles (EVs). Conventional plug-in charging infrastructures are often limited by high installation costs, land usage, and charging downtime. To address these challenges, this project proposes a bidirectional wireless charging station integrated into roadways, powered by renewable energy sources. The system harnesses solar energy through photovoltaic modules and vibrational energy through piezoelectric crystals embedded within road surfaces, adopting the cantilever technique to maximize energy harvesting efficiency. The harvested energy is stored in roadside smart grid modules and later transmitted to EVs using wireless power transfer (WPT) technology. The bidirectional design ensures that energy can flow both from grid to vehicle (G2V) for charging and from vehicle to grid (V2G) to stabilize demand during peak load conditions. The wireless charging station eliminates the need for physical connectors, enabling dynamic charging while vehicles are in motion. The piezoelectric arrays convert mechanical vibrations from vehicle movement into usable electrical energy, complementing solar power to ensure continuous operation even under low sunlight conditions. The cantilever-based mechanism amplifies stress on piezoelectric materials, significantly improving energy output per unit area. A smart control system monitors energy flow, balances load distribution, and ensures maximum efficiency. Artificial intelligence algorithms are integrated to predict traffic density and optimize energy harvesting. The proposed system enhances the feasibility of on-road charging corridors, extending EV range and reducing dependence on conventional charging infrastructure.. The combined use of renewable energy harvesting and wireless charging provides an eco-friendly, cost-effective, and scalable solution for future smart transportation networks. This project contributes to the development of green roadways, where roads themselves act as self-sustaining energy hubs that actively support electric mobility.
