Evaluating charging systems for electric vehicles: Grid vs. Solar power and the role of solar-wind hybrid solutions

This study presents a comparative analysis of the impact of different power supply systems on the performance and longevity of storage batteries used in electric vehicle charging stations. Specifically, it compares conventional electrical grid power with renewable energy sources, focusing on photovoltaic solar energy. An innovative hybrid system combining solar and wind energy is proposed to ensure constant energy availability, especially in regions where weather conditions affect the efficiency of single energy sources. The study integrates Internet of Things (IoT) technology for intelligent energy management, optimizing system performance in real-time based on weather forecasts. Simulation models developed in MATLAB demonstrate that the proposed systems enhance energy stability, reduce dependency on conventional grids, and improve charging reliability. These findings provide valuable insights for manufacturers, policymakers, and consumers aiming to implement sustainable and efficient energy solutions for electric mobility.
