Abstract: The electric vehicle (EV) charging system requires a high-quality power supply to function correctly. The purpose of this study is to look at the impacts of voltage disruption on EV batteries and charging systems, as voltage quality is one of the primary issues in the distribution grid. To increase voltage quality, we also implemented a fault ride through capability (FRTC). The charging system consists of a DC-DC converter and a three-phase controlled rectifier. Lithium-ion batteries are used to simulate EV battery packs. The FRTC system is designed to improve voltage quality by utilizing a dynamic voltage restorer. It protects the charging system and EV batteries against dangerously excessive voltage sag levels. The performance of the proposed EV charging station (EVCS) was evaluated at voltage sag levels of 30%. Matlab/Simulink software was used to analyse the simulation data.
