Design of Small-Scale Movable Charging Unit and Reducing Charge Time using Fuzzy Logic for Electric Vehicle

Now-a-days Electric Vehicles (EV) are drawing attention due to its enormous advantages subduing its setbacks. Lots of research is going on to overcome the prevailing drawbacks, out of which the increased charge time is a highlighted one. Though lots of Fixed Charging Stations have been installed, mobile charging stations are gaining popularity, due to less installation cost and increased customer satisfaction. The development of self -sustainable Small-Scale movable charging unit i.e., mobile charging station, to charge EV, is discussed in this paper. In addition, the charge time for EV is reduced by using Fuzzy Logic. The survey was conducted among EV users to find out the acceptance ratio. The small-scale movable charging unit has been designed and discussed using simulation in MATLAB R2021a. Also, the mathematical model used in designing SSMCU and verification of design along with charge time is discussed. The fuzzy logic was employed to reduce charge time to 2hrs 45 mins for State of Charge from 20% to 100%. The simulation results with fuzzy logic and using conventional method was compared. It was shown that the charge time was reduced by 30.4% with fuzzy logic, when compared with conventional controller for SOC from 20% to 100%. The charging behavior of EV with local load, was also studied using simulation. The Small-Scale Movable Charge Unit was designed as a feasible option to local vendors, with the reduced charge time being an additional feature. Also, the paper aims to satisfy United Nations Sustainable development goals UNSDG-7(affordable and clean energy) and UNSDG- 13(climate action).
