Abstract
In this paper design and development of a Hybrid charging station for electric vehicles is discussed. The charging station is powered by a combination of solar power and grid power. The system works in an integrated way to optimize the energy use from the grid. The system will take the power from solar arrays and directly charge the EV when solar energy is available. When solar energy is not available the system will be powered by the grid. In addition, the system will also deliver the solar power to grid when solar power is available but there is no EV is connected to the charging system. In this mode, the charging station will work as a grid connected solar power plant. Generally, a transformer is used for feeding the low voltage solar power to the grid, whereas in this work a advance high gain boost converter is used to eliminate the transformer. This modification considerably reduces the overall system cost and size. Extensive simulation results are present in this paper to establish the effectiveness of the developed hybrid charging stations.
