The increasing demand for electric vehicles (EVs) has created a need for efficient, eco-friendly, and user-friendly charging systems. This paper presents a solar-based wireless electric vehicle charging system that integrates renewable energy with wireless power transfer technology. The system utilizes solar energy as the primary source, which is stored in a battery and transmitted wirelessly using inductive coupling to charge EV batteries. This eliminates the need for physical connectors, enhances safety, and reduces dependency on fossil fuels.
Introduction
The study presents a solar-powered wireless charging system for electric vehicles (EVs) as a sustainable alternative to conventional wired charging. With the rapid growth of EVs, traditional charging methods face challenges such as inconvenience, safety hazards, cable maintenance, and dependence on grid electricity. To overcome these issues, the proposed system combines solar energy with wireless power transfer (WPT), enabling contactless energy transmission through electromagnetic induction. The literature review highlights that inductive wireless charging provides safe and convenient charging, while solar-powered charging stations reduce reliance on conventional power sources. However, existing systems still face challenges such as low efficiency, coil misalignment, and energy losses. The proposed system uses a primary coil to generate a high-frequency magnetic field, which induces current in a secondary receiving coil. The induced AC power is converted to DC using a bridge rectifier, filtered with a capacitor, and regulated to provide a stable output for charging. The methodology focuses on developing and testing the integrated system, while the experimental results confirm the feasibility of combining solar energy with wireless charging. Although the charging efficiency is currently lower than that of wired systems, improvements in coil design and power electronics can significantly enhance performance. Overall, the proposed system offers an environmentally friendly, safe, and sustainable charging solution that reduces dependence on conventional electricity and supports the future development of green EV infrastructure.
Conclusion
This paper presents a Solar-Based Wireless Electric Vehicle Charging System that integrates renewable energy with modern wireless technology. The system offers a clean, safe, and convenient method of charging EVs. Despite certain challenges, it has strong potential for future applications in smart cities and green transportation.
