Abstract: This paper provides an overview of the designing principles of fluid vehicles (15 aged, engine damaged, and going for trash vehicles) into the electric vehicle conversion process. The paper describes the development of an electric vehicle powertrain and the design and analysis of the different parts of vehicles like a transmission system (bush, bearing, and sprocket) battery, geared motor, motor, and controller. It also, explains the design rules and calculations of the powertrain subsystem. Electric vehicles are powered by geared electric motors (DC) which are powered by the battery through the electric converter. Conventional vehicle loses their efficiency after a long duration. Retrofitting gasoline-powered vehicles into an electric vehicle is a cost-effective and beneficial process. During the retrofitting, the powertrain, electrical parts, and vehicle parts (swing arm, bush, and bearing) are required to modify and the remaining subsystems like suspension, steering, and braking will be the same. In the powertrain part, the vehicle consists of a Geared motor, motor controller, battery, and battery management system, and transmission system (chain drive).

Keywords: Fluid vehicles, Electric vehicles, lithium-ion battery, Controller, Geared motor, transmission.
