Design, simulation and analysis of a fast charging station for electric vehicles

With the advent of Electric Vehicles into existence, there is a need to develop a significantly charging infrastructure that will make electric cars more attractive and lead to higher adoption rates. In light of the increasing demand for EVs, there is a need to develop a fast-charging station that cuts back on the charging time and hence overcome range anxiety. Fast charging stations are capable of reducing the charging duration by up to 30 min. By way of sustainable development and availability of secure energy, the focus of the paper is to develop the fast charging station of various Electric vehicles/Plug-in Hybrid Electric vehicles as per the grid power supply and their worldwide implementation. In this paper, we have designed a system for the fast charging of electric vehicles in which we provide continuous feedback to the dc-dc converter considering the battery SOC by using a battery pack control module and tuning the PI controller. To reduce the fluctuation in input supply, we have studied and implemented a cosine firing scheme based voltage regulator and electronic tap changer (ETC) out of which ETC provides a very promising solution. Further, the impact of charging with time on battery resistance has also been discussed.
