Due to the 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 one of possible solution. Thanks to the state-of-art electric motors, power electronics, embedded power train controller, energy storage systems such as batteries and ultra capacitors, 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 thesis some of the principles of modeling and simulation are discussed. Some tests in order to find the internal parameters of the battery are explained and based on the data from the tests a Lithium-ion battery and electric vehicle performance is evaluated by using model which is whuch us dveloped using Simulink/Matlab. The dynamics of the vehicle in terms of longitudinal and lateral forces are discussed and a model representing the aerodynamic and rolling resistance are developed in Simulink. Given the data obtained from the test data from a Proton SAGA manufactured by the PROTON Company, the performance of the vehicle in terms of battery consumption, acceleration and maximum cruise speed is analyzed.
