The Simulation of a Full Electric Vehicle Using the City Cycle

Abstract

In this study, the design and simulation of an electric vehicle commonly being started to be used in twenty-first century have been done by Matlab program. As the vehicle model, a whole-electric vehicle has been accepted as model. In modeling an electric vehicle, the measures of an usable vehicle in today’s conditions and the technical features of electric motor commonly used in electric vehicle’s technology have been utilized. This model has been composed from DC motor used for electric motor’s stimulation and from the battery which provides enough energy to vehicle. In modeling electric vehicle, the UDDS city cycle has been used. According to this cycle, powers moving the vehicle and strength powers preventing its movement have been calculated and a data file which describes the movement characteristic of vehicle has been composed. In addition to this data file and UDDS cycle, the rates of power and torque which the vehicle need have been calculated. For the same cycle, the rates of essential power and torque for vehicle’s stimulation and the torque, power and current changes of electric motor have been obtained depending upon time.
