Off-Board Li-Ion Battery Fast Charger with Two-Stage Bidirectional Converter for Electric Vehicles

Abstract

Electric vehicles will eventually replace gasoline-fueled automobiles, the demand to maintain these electrical vehicles have been increased. In this the fast-charging technique has been represented while connecting to the green power sources. This study presents a unique design for an off-board three-phase charger with many modes of operation for quick battery charging for electric vehicles. The fast charging of the electrical battery is developed in two stages. It is an integration of the multiple bridge rectifiers as voltage source, which controls the charging current to the second stage. It is made up of a bidirectional three-level asymmetrical voltage-source converter that regulates current flow during the charging of electric vehicles. The result was obtained by using MATLAB/SIMULINK.
