MODELING AND SIMULATION OF ELECTRIC CARS USING MATLAB - SIMULINK

The desire to reduce pollution and price instability generated by the major share of fossil fuel use requires firm solutions for ecological transition of the economy, which must provide access to clean, safe and affordable energy. An important, seriously affected sector, being a competitive field with consistent limitations, is the transport system, where the use of alternative fuels or the use of electric cars is definitely a solution. The present paper presents an evaluation, through simulation in MATLAB-Simulink, of influence of parameters such as: vehicle frontal area, tire pressure, wind speed, road slope, aerodynamic coefficient and rolling resistance coefficient, in the power and energy balance and aspects that influence the optimal dimensioning of batteries and electric motor.
