Design of a solar-powered electric vehicle charging station

Abstract

This manuscript presents the design of a solar-powered electric vehicle (EV) charging station in Villavicencio, Colombia, aimed at reducing reliance on the utility grid, lowering energy costs, and minimizing environmental impact. The station designed integrates a photovoltaic system to harness renewable energy, ensuring a sustainable and cost-effective charging solution. It accommodates both AC and DC fast charging options to meet diverse vehicle requirements. The design considers available space, energy generation potential, and financial feasibility to maximize efficiency and return on investment. A technical analysis of battery storage, power electronics, and system configuration is provided, along with a cost-benefit assessment. Simulation results confirm the station's ability to deliver stable power under varying conditions. With an estimated payback period of 2.8 years, this project demonstrates the economic and environmental advantages of solar-powered EV infrastructure, supporting the transition to clean transportation in Colombia.
