An international research team, including scientists from Pakistan, Qatar, UAE, and Iran, conducted a study on optimizing EV charging stations using renewable energy sources. The study focused on a standalone EV charging station in Jamshoro, Pakistan, that integrated solar energy, hydrogen, and a lithium-ion battery system. The researchers used simulation software to analyze two scenarios: a hybrid PV-hydrogen system and a hybrid PV-hydrogen-battery system. They found that the hybrid system was more cost-effective, with a lower levelized cost of electricity at $0.358/kWh compared to $0.412/kWh for the PV-hydrogen system. The hybrid system also offered significant financial and economic benefits. The power generation was distributed with 87.4% from PV panels and 12.6% from fuel cells. The study, titled 'Techno-economic analysis of standalone hybrid PV-hydrogen-based plug-in electric vehicle charging station,' highlighted the potential of the hybrid system for off-grid renewable energy solutions. The findings emphasized the importance of integrating multiple energy sources for efficient and sustainable EV charging infrastructure.
