Retrofitting of an Engine Powered Vehicle into an Electric Vehicle

This paper provides an overview of the designing principles of a conventional vehicle into the electric vehicle conversion process. The paper describes the development of electric vehicle powertrain and the comparison of the different parts of electric vehicles like a battery, motor, motor controller and transmission. Also, explains the design rules and calculations of the powertrain subsystem. Electric vehicles are powered by traction motor or electric motor (AC or DC) which are powered by the battery through the electric converter or an inverter. Conventional vehicle loses their efficiency after long-duration. Retrofitting of gasoline powered vehicle into an electric vehicle is cost effective and beneficial process. During the retrofitting, powertrain and electrical parts are required to modify and remaining subsystems like, suspension, steering, and braking will be the same. In the powertrain part, the vehicle consists of a BLDC motor, motor controller, battery and battery management system [1] and gearbox with differential.
