A simulation study for the performance of electric vehicles

Electric vehicle (EV) is one of the most promising candidates for future transportation because of its zero emission, silent driving, and higher efficiency than internal combustion engine vehicle. This paper presents a simulation program, which is implemented on Matlab/Simulink, for the study of EVs. The developed simulation program is composed of several modules such as battery, motor, vehicle, and driver modules. Graphical User Interfaces (GUIs) for the modules are provided, which can make the users use the program in an easy and convenient way. Using this simulation program, the capacity of the battery can be chosen based on a given EV system and driving condition. A regenerative braking strategy, which is based on the ideal braking force distribution on front and rear axles, is applied to this simulation program. In previous research, the motor and inverter efficiencies were considered as one value, but in this research they are considered separately since there are different inverter and motor research teams in this project. This is necessary to develop both inverter and motor modules.
