Design of a smart and fast charger for Electric Vehicles

Electric vehicles (EVs) have proven to be a perfect short-term solution to reduce gas emissions and air pollution worldwide. However, the widespread accessibility of EVs is limited by diverse economic, technical, and policy restrictions. The battery's short lifetime and the long charging time are among the most critical EV issues. Therefore, there are extensive research works that deal with the EV battery charger design. In this paper, the design and simulation of a smart and fast EV battery charger based on a Vienna Rectifier (VR) and an isolated Dual Active Bridge (DAB) converter is presented. The designed charger is based on the CHAdeMO charging protocol allowing a smart data transfer between the battery and the charger.Simulation tests performed on Matlab/Simulink prove the efficiency and the rapidity of the proposed charger.
