Vani, B.V.Kishan, D.Ahmad, M.W.Hanumanthakari, S.Reddy, B.N.K.2026-02-0620222022 12th IEEE Symposium on Computer Applications and Industrial Electronics, ISCAIE 2022, 2022, Vol., , p. 191-195https://doi.org/10.1109/ISCAIE54458.2022.9794511https://idr.nitk.ac.in/handle/123456789/29952In Present day various countries all throughout the world have taken on Electric Vehicles (EVs) to diminish air pollution and fuel consumption. In coming years, Electric Vehicles are bound to become crucial in the transport field. Subsequently, the charging approaches are in the same line. This paper presents an outline of the current and proposed EV charging approaches and optimization methods. Especially the various EV charging methods like battery exchange, conductive charging and wireless charging are presented. Next, some of the EV charging/discharging optimization methods are examined. On the basis of investigation, a few proposals are put forward for future research. © 2022 IEEE.Battery chargerElectric vehicleEnergy storage unitOptimization
