Fast Charging Station for Electrical Vehicles Based on DC Microgrid by using Fuzzy Logic Controller

The rapid adoption of electric vehicles (EVs) has heightened the need for fast charging stations that can meet high-power demands efficiently. Conventional charging methods struggle with long durations and grid instability, especially when charging multiple vehicles simultaneously. This paper presents a fast charging station powered by a DC microgrid integrated with renewable energy sources, particularly solar photovoltaics (PVs), to mitigate the impact on the power grid. A fuzzy logic controller (FLC) is employed to regulate charging process, optimizing energy flow based on battery state-of-charge (SOC) levels. By utilizing a multistep constant current charging algorithm, the proposed system ensures faster charging while maintaining battery health. Simulation results demonstrate significant reductions in grid voltage dips and transformer overheating. A software validates the proposed methodology, highlighting the system's potential for sustainable EV charging infrastructure
