Modeling and simulation of electric vehicle power system

The electrical power system (EPS) of an electric vehicle consisting of batteries, the motor and driving subsystem, has been modeled. A battery is modeled with an electrical circuit representing the features of a real battery. The driving subsystem is modeled as three different levels, that is, exact, average and functional models. The load profile includes road information, speed profile and EV mechanical parameters, which are incorporated into a reference torque in the driving subsystem model. A system model simulates the performance of the electric vehicle, incorporating the energy balance, battery status and electrical stresses of each subsystem.
