Modeling and simulation of electrical vehicle in VHDL-AMS

Regarding limitation of fossil fuels and the high consumption rate of this energy for transportation, inclination of vehicle industry toward other sources of energy is inevitable. Electric vehicles and hybrid vehicles could be a good solution. Thanks to the state of art of electric motors, power electronics, embedded power train controller and energy storage systems like batteries, the performance of the vehicle could become more and more energy efficient. Since the integrating of all these components in a drive train configuration could be a challenge for the manufacturer, computer simulation and modeling before prototyping could be really beneficial in terms of cost, safety and design performance. In this paper some of the principles of modeling and simulation are discussed. As traction chain plays a significant role in electric vehicles, its modeling and optimization has a significant importance. As an electric vehicle is a multidisciplinary system, the new standard VHDL-AMS since 1999 is suitable for its modelling and simulation in the same software environment and with different abstraction levels.
