Performance Analysis of Fast Charging Stations for G2V and V2G Micro-grid Systems

In order to promote the switching from ICE vehicles to more environment friendly EVs, a network of fast charging stations is necessary. A lot of research is being conducted in this area in order to design efficient models of chargers along with developing new technologies to mitigate the current problems encountered such as the charging time, incapability to charge multiple vehicles at a time etc. This paper presents the different ways of classifying EV battery charging technologies and also a topological survey of different charging stations proposed in the literature. A three-phase bidirectional charger and a modular fast charger proposed in the literature are also presented along with their modelling, control strategies and simulation results to analyse their respective performances.
