The rapid growth of electric vehicles (EVs) and renewable energy integration has created the need for efficient and intelligent charging infrastructure. This work presents a single-stage photovoltaic (PV)-based EV charging station capable of bidirectional power flow and power quality enhancement. The system integrates a PV array directly with a DC-link, eliminating the need for an additional DC-DC boost converter, thereby improving efficiency and reducing cost. A bidirectional converter enables both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) operations, allowing EV batteries to act as distributed energy storage units. The proposed control strategy regulates active and reactive power, ensuring low harmonic distortion and near-unity power factor. Additionally, the system supports seamless transition between grid-connected and standalone modes, enhancing reliability during grid disturbances. Simulation and analysis demonstrate improved grid stability, efficient energy utilization, and compliance with power quality standards, making the system suitable for modern smart grid applications.
