Environmental benefits of Electric Vehicles (EVs) are associated with reduction of direct air pollutants and reduction of greenhouse gases. In this paper, a novel solar-powered EV Charging Station (EVCS) is offered with the integration of a grid-based energy management system and a high-efficiency Double-Stage Coupled Inductor Boost Converter (DSCIB). A new Arctic Puffin Optimized (APO) Proportional-Integral (PI) controller is employed for preserving a constant DC-link voltage and optimal system performance. This approach optimizes the energy transfer efficiency and enhances a stability under dynamic operating conditions. DC bus is linked to electrical grid through LC filter and three phase Voltage Source Inverter (VSI), which allows bidirectional power flow and reactive power support. PI-based control loop is employed for grid synchronization, to properly balance the active and reactive power. The charging and discharging processes of EV battery are controlled via a bidirectional DC-DC (BDC) converter, which is structured with the PI control strategy to precisely control the voltage and current. This configuration offers the capability of battery-to-grid without any interruption and fast charging of EV batteries during excess PV generation. The MATLAB simulation results shows proposed architecture offers a promising option for sustainable EV integration in grid applications because of the coordinated control framework. From simulation converter attain efficiency of 98.4% and decrease THD of 1.02% ensure effective energy flow, voltage stability, and grid support.
