Dual Source Renewable Charger For Electrical Vehicles

The study introduces a novel Dual Source Renewable Charger for electric vehicles (EVs) that uses wind and solar energy to improve charging dependability and efficiency. Under ideal circumstances, the system's overall energy efficiency ranges from 85 to 90%, which is a 15–20% increase over single-source renewable charging systems. A typical EV battery can be charged in 6–8 hours thanks to its 1.5–2.5 kW combined power output under average sun irradiation (800 W/m<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup>) and wind speeds (5–7 m/s). The system includes a hybrid renewable energy model with solar panels and a vertical-axis wind turbine, as well as an intelligent power management unit that dynamically prioritizes energy sources according to availability and environmental circumstances. The design incorporates a 10 kWh energy storage system to mitigate energy intermittency, guaranteeing continuous charging for 4–6 hours during periods of low renewable energy supply. By restricting charge/discharge cycles to 95% depth of discharge (DoD), the adaptive charging approach incorporates a bidirectional DC-DC converter, prolonging battery longevity by 20–25% in comparison to traditional methods. The charger also lowers operating expenses and carbon impact by reducing grid reliance by 60–70% during periods of peak renewable energy output. The system's Internet of Things (IoT) features allow for real-time monitoring and optimization, improve user comfort and grid compatibility, and reduce energy losses by 5–10% through adaptive power management and predictive maintenance.
