Design of Efficient Electric Vehicle Charging Stations Using Renewable Energy Sources in Nigeria
Keywords:
Electric, Vehicle, Charging, solar photovoltaicAbstract
The rapid adoption of electric vehicles (EVs) globally is driving demand for sustainable and resilient charging infrastructure, particularly in regions with unreliable grid systems. This study presents a techno- economic framework for designing efficient EV charging stations powered by hybrid renewable energy specifically solar photovoltaic (PV) and wind systems within the Nigerian context. The system integrates smart charging, battery energy storage, and grid backup to address the country's power reliability challenges. Using HOMER Pro simulation, the study evaluates system performance under varying climatic and economic scenarios. Results show that a hybrid solar-wind system with battery storage can supply over 85% of energy demand, reduce grid dependency, and cut CO₂ emissions by more than 12,500 kg annually. The system achieved a levelized cost of energy (LCOE) of 0.172 USD/kWh and a net present cost of $154,230, with a payback period of 6.2 years. These findings demonstrate the viability of renewable-powered EV infrastructure in emerging markets. The study concludes with policy and investment recommendations to scale clean mobility solutions across Nigeria.
