Electric Vehicle Drive with MATLAB/Simulink

The paper presents the simulation of a basic electric vehicle motor-drive system that is used to investigate power flow during both motoring and regeneration.

The simulation assumes a DC permanent magnet motor, an ideal motor controller combined with a proportional-integral controller, and the electric vehicle battery.

The model can be used to evaluate the electric drive’s energy flow and efficiency for specific speed and torque load conditions. Some of the key system parameters were specified and others were modeled as ideal.

A stable MATLAB/Simulink model was developed and validated. It was then used to determine the system performance and energy flow over a given set of motoring and regeneration speed/torque conditions.

The model could be used to augment instruction in energy conversion or vehicle systems courses.
