Abstract - The rapid development of Electric Vehicles necessitates the implementation of effective, sustainable, and user-friendly charging systems. This project envisions a complete solution for EV charging with a combination of solar energy harvesting and wireless power transfer (WPT) technology. Wireless charging with inductive coupling using coils offers an easy and safe alternative to the traditional plugin system by eliminating physical connectors. The technology utilizes a photo-voltaic panel configuration to convert solar radiation into electricity, and the electricity is conditioned and remotely transmitted through wireless means to the on-board receiver coil of the vehicle. The practice enables clean energy consumption while improving usability and reducing infrastructure wear and tear. Some of the key components include solar charge controllers, power converters, highfrequency converters, and resonant inductive coils. Merging contactless solar-poweredchargingandrenewablesolarpower reduces grid dependence to a minimal extent while ensuring carbon footprint saving. This is a paper illustrating the system layout, operating paradigms, efficiency and aligning issues, as well as potential applications to static and dynamic charging environments in electric vehicles. The proposed method represents a pivotal achievement toward eco-friendly and independentEVinfrastructurebuildup.

1.INTRODUCTION

WiththeincreasedpopularityofElectricVehicles,thedemand for environmentally friendly and cost-effective charging sources increases. Traditional plug-in charging solutions are sometimes troublesome, wear-prone, and dependent on human intervention. Wireless power transfer offers an appealing solution through contact less inductive charging of power transferred from one coil at a charging station to another located inside the vehicle without any physical contacts.

As the world moves towards greener and cleaner modes of transport, Electric Vehicles are gaining popularitysince they are green andenergyefficient. But mass use of EV alsorequiresefficient, effective, and green charging systems. Conventional plug-in charging, as effective as it is, isclumsy,involves physical contact, and depends significantly on grid-based power, which in turn tends to be derived from non-renewable sources.Wireless charging or inductive charging offers a contemporary and easy alternative. The technology conveys power using two coils one fixed on the ground and the other installed on the vehicle using an electromagnetic field. It does away with cables andconnectors, lessenswear and tear,and provides greater convenience and automation in charging. Additional reduction inenvironmentalimpact and making thesystem a complete green onecan be achieved by incorporating solar power as the main source of power. Photovoltaic panels can beused to capturesunlight and convert it into electricalenergy to drive the wireless chargingsystem. Thecombination of solarpower andwireless coil technologyleads to a clean, renewable, andefficient methodof EV charging withminimal use of fossil fuels andlowergreenhouse gasemissions.

This project will develop and install asolar-powered wirelesselectricvehiclecharging system combining the advantages of renewable energy and cutting-edge charging technologies.

With the combination of solar panels, power managementcircuits, and inductive coils, this system presents a future- oriented sustainable solution to electric mobility. It can beappliedtomultiplelocations like residential driveways, public parking garages, or specialized solar charging stations, hence enabling a cleaner, more convenient, and more technologically sophisticatedtransportationsystem.

The system continuously monitors solar input power, battery status,and vehicle presence to adjust charging parameters asneeded. A user interface is provided for control and monitoring using a smart phone or web-basedapplication.
