Off-line and real-time simulation Modelling of Electric Vehicle power train

Abstract

Modelling of Electric Vehicle power train is analysed to evaluate the energy flow between electrical and mechanical sub systems. The indigenous platform SEQUEL gives more user configurability and new user element support for offline simulation. State-of-the-art real-time simulation facilitates the controller development and evaluation before making the plant prototype of system like EV. Because of the high frequency switching in power converter/inverter and due to complex motor dynamics detailed simulation of EV power train need high computation with simulation delta time of the order of 1-2 micro sec. This is practical in offline simulation where as presently available real-time simulators can do simulation in 50-100 micro seconds only. So the concept of average modelling is introduced in EV sub-systems to derive appropriate models to implement real time simulation.
