Dynamic Modeling and Simulation for Battery Electric Vehicles under Inverter Fault Conditions

Abstract

This paper presents a dynamic modeling, simulation, and analysis of a Battery Electric Vehicle (BEV) according to vehicle dynamic characteristics. Mathematical model variants for the components of BEVs can be modeled and investigated using the Matlab/Simulink software. In order to compare the dynamic performance of BEVs under inverter fault and normal conditions, the CarSim co-simulation platform is configured with real vehicle calibration data. Using this approach, it was possible to quickly check for dynamic performance issues of an electric vehicle without incurring the time delay and cost. The simulation results such as motor output, vehicle speed/acceleration, and propulsion forces are discussed and compared for each drive mode.

Holistic simulation for integrated vehicle design

“…Connection between Simulink and ADAMS was established using the virtual server option. G. Park et al[59] built an electric vehicle model in CarSim and integrated it in S-Function form into a global Simulink model containing battery, power electronics, and driver subsystems with the purpose of investigating the effects of inverter faults on vehicle performance.…”

Front-to-rear torque vectoring Model Predictive Control for terminal understeer mitigation

“…Various studies have been analysing the influence of faults on the dynamic behaviour of a vehicle, e.g. (Jonasson et al 2008), (Li et al 2014) and (Park et al 2012).…”
