DESIGN AND FABRICATION OF MULTI JUNCTION PIPE CONNECTOR

The proposed Hybrid Solar Tracking, Wind Energy, and AC Mains Based EV Charging Station provides a sustainable and reliable approach for renewable-energy-powered electric vehicle charging. The system combines a 30 W solar panel with an LDR-based automatic tracking mechanism, enabling the panel to follow the direction of maximum sunlight and improve energy harvesting. A 10 W wind turbine provides additional renewable power during suitable wind conditions. The generated energy is regulated using a DC-DC boost converter and stored in a rechargeable battery for later use. An optional AC mains supply provides backup power whenever renewable generation is insufficient. The Arduino controller, L298 motor driver, voltage sensor, and LCD display enable automatic tracking, monitoring, and basic system control. The stored battery energy can supply the EV charging unit and DC loads, while an inverter supports AC loads. Overall, the proposed system demonstrates the feasibility of integrating multiple renewable sources with energy storage and backup supply, reducing  dependence  on  conventional  electricity  and supporting cleaner transportation. The prototype can serve as a foundation for developing larger and more efficient renewable-powered EV charging stations.
