System Design and Realization of a Wireless Electric Vehicle Charging System

The rising adoption of electric vehicles (EVs), there is a growing demand for sustainable and efficient charging infrastructure. This study presents the design and implementation of a solar-powered, wireless charging system for EVs that addresses two primary challenges in transportation: dependency on fossil fuels and environmental pollution. EVs have already demonstrated reduced operational costs and environmental impact by replacing traditional fuel with electricity. The proposed charging system introduces a novel solution that eliminates the need for physical cables and external power sources. It utilizes solar energy as the primary input to maintain continuous charging, enabling EVs to recharge even while in motion. The system architecture comprises key components such as solar panels, energy storage batteries, LCD interfaces, charge controllers, AC-to-DC converters, inverters, ATmega microcontrollers, and inductive coils for wireless energy transfer. Solar panels generate direct current (DC) electricity, which is regulated and stored in batteries. This stored DC power is then converted to alternating current (AC) for wireless transmission via primary coils embedded in the infrastructure. The receiving EV, equipped with secondary coils and an AC-to-DC conversion module, captures and utilizes the transmitted power for battery charging. This dynamic, integrated system illustrates the potential of wireless solar charging to enhance the practicality and sustainability of electric mobility, reducing charging downtime and infrastructure limitations.
