Abstract

This paper presents MATLAB/Simulink based modeling and simulation of battery-powered electric vehicle (BEV) to estimate power consumption rate at development stage of a new electric motor. The model of BEV consists of not only the main power components such as a motor, an inverter and a battery, but also includes a driver, a controller and vehicle dynamics. In the model, a simple vehicle model based on N ewto-nian mechanics is constructed and it is possible to simulate the vehicle running by a motor using electricity obtained from a battery as a power source. JC08 mode as one of the driving pattern mode for evaluating the power consumption rate is used to determine the commanded values for the vehicle running. The power consumption rate is calculated from the distance and the power consumption of the battery. To demonstrate the validity of the model, this paper deals with NISSAN LEAF EV specifications to compare power consumption rates.
