The number of countries with electric vehiclesontheroadissteadilyrising. Inadditiontohelpingtheenvironment,electricvehicleshaveproven useful in cutting down on transportation costs by substituting expensive fuel with much more affordable power. Here, we create a novel and effective answer to this problem by designing an electric vehicle charginginfrastructure.

For its construction, the system employs a solar panel, battery, transformer, regulator circuitry, copper coils, AC to DC converter, atmega controller, and LCD display. This technology follows the ideology that charging electric vehicles can be done without having to pull over to a charging station. So, the technology proves the viability of a road-integrated, solar-powered wireless charging system for EVs.

Introduction

Electric vehicles (EVs) are emerging as a key future transportation mode due to their environmental benefits, such as reduced CO? emissions and lower fossil fuel use. Despite their advantages like lower operating costs and minimal environmental impact, EV adoption is limited by high vehicle costs, insufficient fast-charging infrastructure, and limited driving range. EVs can be fully or partially electric, and improving charging efficiency is critical for their widespread use.

Wireless power transfer (WPT) technology, particularly through electromagnetic induction, offers a promising solution by enabling contactless charging of EVs, eliminating the need for plugs and potentially allowing dynamic charging while driving. Integration with renewable energy sources like solar power enhances sustainability. Studies show advancements in solar-powered wireless EV charging systems, efficient energy conversion, and vehicle-to-grid (V2G) technologies that balance grid demands and battery health.

The project discussed involves developing an IoT-enabled wireless charging station combining solar panels, batteries, transformers, and control circuits for efficient, real-time monitored EV charging. The system aims to provide continuous, convenient charging, especially for long-distance travel where charging stations are scarce. Key goals include achieving over 90% wireless charging efficiency, compatibility with existing EVs, safety, and scalability.

Simulations of the wireless charging system demonstrate promising efficiency and stable power transfer. Challenges such as battery range anxiety, long charging times compared to refueling gasoline cars, and the lack of widespread fast-charging infrastructure remain. However, wireless charging systems powered by renewable energy and integrated with smart grids could address these issues, promote EV adoption, reduce greenhouse gas emissions, and improve travel convenience and road safety.

Conclusion

Electric cars (EVs) are essential in the present when the environment has worsened so significantly. The government of plans to completely phase out diesel cars by the year 2030. Because waiting for an electric vehicle to charge is the biggest drawback to EV adoption, rapid charging technology and charging stations are essential to the widespread acceptance of EVs. A reliable charging network will be essential to the success of this shift. The broad adoption of EVs has the potential to significantly disrupt the reliability of the power grid. A renewable energy system is at the heart of the \"solar-based wireless EV charging\" initiative. A lead-acid battery stores the electricity generated from the sun. The BMU allows for the installation of a completely wireless charging infrastructure. This saved power is used to refuel EVs.
