Development of Charging System for Multiple Electric Vehicle Using Bidirectional DC–DC Buck–Boost Converter

Electric vehicle (EV) charging system integrated with DC microgrid and nonconventional energy sources will give a way for the envisioned future of EV charging infrastructure. In this paper, mobile charging station (MCS) to charge multiple electric vehicles has been designed and developed. The MCS is integrated with DC microgrid and is operating in four different modes. The charging terminals of grid-connected MCS are developed with DC/DC bidirectional buck–boost converter. The charging station is modelled using MATLAB–Simulink, and the system operation has been verified for the different operating modes. A laboratory prototype has been developed, and the results show the practical possibility of the MCS.
