In this paper, the implementation and control of solar photovoltaic (PV) array, and wind energy conversion system (WECS) based charging station is proposed for charging the electric vehicle (EV) and to power the domestic loads uninterruptedly. Grid connected mode (GCM) and islanded mode (IM) of operations are taken for the proposed control. In IM, the EV directly takes power from the DC link using bidirectional DC-DC converter. However to supply the household loads, it generates a sinusoidal voltage at common point of coupling (CPC). In GCM, the charging system exchanges power with the grid at unity power factor (UPF), while maintaining the grid current total harmonic distortion (THD) less than 5% even though the current drawn by the home loads, are non-sinusoidal. Moreover, the control of the charging station also includes the voltage synchronizing strategy that ensures the smooth transition between the GCM and IM of operation. The multimode operation and power management under different mode of operation of the charging station is validated through the laboratory scale prototype.
