Final Project: Electric Rickshaw modelling

INTRODUCTION: Let us first look at the layout and working of an electric rickshaw. Electric rickshaws have the same principle as EV's. They also run on lithium-ion battery packs. The motors generally used here are DC motors. Mostly, electric rickshaws are rear wheel driven.  The drive train is seen above. The power for…
