Abstract:
This paper explores the integration of solar photovoltaic (PV) technology into electric vehicle (EV) charging infrastructure, emphasizing both environmental benefits and the growing demand for sustainable transportation solutions. A significant barrier to EV adoption is the limited availability of charging stations and grid instability during peak hours, which prolongs charging times. To address these challenges, the project designs a solar-powered EV charging station that combines a 3 MW PV array, direct current (DC) converters with Maximum Power Point Tracking (MPPT), DC-DC chargers, and inverters. The PV array consists of 11 series modules and 1300 parallel strings, optimized to reach maximum output at 25°C and to store energy at a peak voltage of 28V. The charging system connects to a 400V grid and includes components such as a bidirectional inverter and integration with public utility infrastructure. Simulation results show that the MPPT technique extracts 68W within 0.3s, demonstrating efficient energy capture while maintaining low processing costs. The analysis of daily generation confirms realistic daily generation metrics, where achieves 6.74% of its annual generation target per day, aligning with practical solar variability. This study provides actionable insights into the deployment of solar powered EV charging stations and advances in grid-connected EV infrastructure, supporting the scalability of sustainable energy solutions in transportation.
