Multilevel current charging system design and analysis for electric vehicles

electrical engineering

Due to its higher energy density, longer lifespan, and superior power density, lithium batteries have emerged as the primary energy source for the development of electric vehicles (EVs) in recent years. Vehicles that run on batteries need to have their batteries charged quickly and effectively. While filling up a gasoline-powered car just takes a few minutes, charging an electric vehicle (EV) can take anywhere from four to six hours, depending on the C-rate. In this study, a two-wheeled electric vehicle's multicurrent charging mechanism is modelled and simulated. The suggested technique derives the charging current via a buck converter power conditioning circuit using a closed-loop control. The circuit is simulated in the MATLAB/Simulink environment to validate the suggested charging method. The results are then compared with those of the constant current (CC) and constant current-constant voltage (CC-CV) charging methods.
