Overview of quality of service evaluation of a charging station for electric vehicle

Abstract

The world has grown quickly and almost all the transportation equipment work with fossil fuels. Since electrical energy can be generated from clean and efficient sources, the world energy consumption should change to electric type. Charge stations should be bidirectional so that power could be transferred from grid to vehicle and vice versa. In this condition, the grid is prone to new kind of challenges. When the section analysis is incorrect, the grid may come down with over load, voltage instability and protection error. In this paper, we illustrate some problems of the grid with EVs and other issues for analysis. If the problems of the grid are detected beforehand, they will be easier to solve.
