This paper explores the integration of solar energy and energy storage systems (ESS) to enhance the efficiency and sustainability of electric vehicle (EV) charging. The study focuses on a solar-integrated charging system, which uses MATLAB simulations to model and analyze the performance dynamics of harnessing solar energy as the primary Direct Current (DC) EV charging source. The system includes solar PV panels, an ESS, a DC charger, and an EV battery. Key findings include a 47% increase in solar PV output power when solar irradiance increases from 400 W/m² to 1000 W/m², and a 38% boost in ESS output power under similar conditions. The research highlights the importance of optimal solar panel placement in high irradiance areas and the positive correlation between elevated irradiance levels and the EV battery's State of Charge (SOC). The study also discusses the limitations of the current research, such as the need for more nuanced examination under varying environmental conditions and the assumption of constant efficiency for electrical components. Overall, the research contributes to the development of a sustainable and efficient EV charging infrastructure, paving the way for a more resilient and environmentally friendly future of electric mobility.This paper explores the integration of solar energy and energy storage systems (ESS) to enhance the efficiency and sustainability of electric vehicle (EV) charging.
