In this work, a charging station for electrical vehicle (EV) integrated with a battery energy storage (BES) is presented with enhanced grid power quality. The positive sequence components (PSCs) of the three phase grid voltages are evaluated for the estimation of the unit templates (UTs) and the reference grid currents. The EV and BES are connected at dc link using a bidirectional buck-boost converter. During the daytime, EV takes power from the solar array, while in its absence, it consumes the power from the grid. Additionally, when the system is connected to the grid, the point of common coupling voltages synchronizes with the voltages of the grid. Tests are conducted on a hardware prototype developed in the laboratory for the validation of the satisfactory response under different dynamics conditions.
