This document summarizes a student project to simulate an onboard charger for a 48V battery electric two-wheeler vehicle using MATLAB/Simulink. The project aims to design an AC to DC rectifier, DC to DC converter, and charge controller. It will provide efficient power distribution and optimize electronics. Adopting a 48V electrical system provides benefits like more power, torque and intelligence for electric vehicles. The document outlines the need for the project, components, block diagram, and circuit diagrams that will be modeled in MATLAB/Simulink.
