The rapid adoption of electric vehicles (EVs) necessitates sustainable and efficient charging solutions. This project focuses on the design and simulation of a bidirectional converter for solar-powered EV charging stations, enabling both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) energy transfer. The proposed system integrates a PV panel, an MPPT boost converter, a bidirectional DC-DC converter, and a battery storage unit to ensure efficient energy utilization. The MPPT algorithm optimizes solar energy harvesting, while the bidirectional converter facilitates dynamic power flow between the EV battery, grid, and storage unit. This system reduces dependency on fossil-fuel-based grid power, enhances grid stability, and supports renewable energy integration. The MATLAB/Simulink-based simulation validates system performance, showcasing improved efficiency, reliability, and cost-effectiveness compared to conventional unidirectional charging stations.
