In the quest for sustainable urban mobility, a groundbreaking study published in the IEEE Access journal, titled “Numerical and Experimental Analysis of Photovoltaic-Integrated Energy Storage System for Electric Vehicle Fast Charging,” offers a promising blueprint for smart cities. The research, led by Furkan Dincer from the Department of Electrical and Electronics Engineering at Kahramanmaraş Sütçü İmam University in Türkiye, explores the integration of battery energy storage systems (BESS) with solar power to create a robust and eco-friendly electric vehicle (EV) charging infrastructure.
The study focuses on a practical scenario where seven distinct EV models, each with varying battery capacities and ranges, are used for daily commuting activities. The proposed system involves DC fast-charging units equipped with BESS capable of charging up to 70 EVs daily. The BESS is connected to a grid powered by a solar power plant (SPP), which has been experimentally designed to generate sufficient electricity to power 10 charging points, accommodating up to 700 EVs per day.
“Our model demonstrates that a single SPP installation can supply the entire network of 10 fast-charging stations deployed across the city,” Dincer explains. This integration not only enhances the reliability of the charging infrastructure but also significantly reduces carbon emissions. The study reveals that the system can enable up to 1,518 tons of CO2 reduction per year, making it a viable solution for improving air quality and promoting sustainable practices.
One of the key findings of the research is the trade-off between battery life and flexibility, as assessed through different state of charge analysis (95–70%). This insight is crucial for optimizing the performance and longevity of BESS in real-world applications. Economically, the proposed system is also attractive, with an 8.06-year payback period, making it a financially sound investment for the energy sector.
The implications of this research are far-reaching. By integrating photovoltaic systems with energy storage, cities can reduce their dependence on fossil fuels and move towards a more sustainable energy future. “This study provides a comprehensive framework for the deployment of EV charging stations powered by renewable energy sources,” Dincer adds. “It paves the way for future developments in low-carbon mobility and smart city planning.”
As the world continues to transition towards electric vehicles, the findings of this study offer valuable insights for policymakers, urban planners, and energy providers. The integration of solar power and battery storage systems not only enhances the efficiency of EV charging infrastructure but also contributes to the broader goals of environmental protection and sustainable development. With the increasing demand for clean energy solutions, this research is poised to shape the future of urban mobility and energy management.
Published in the IEEE Access journal, the study underscores the potential of renewable energy integration in creating a sustainable and resilient energy ecosystem for smart cities. As the energy sector continues to evolve, the insights from this research will be instrumental in driving innovation and fostering a greener, more sustainable future.
