An integrated approach for modelling Electric Powertrain

Abstract

This paper presents an integrated approach to model and analyze electric powertrain of an automobile. This multi-domain model predicts the energy flow, range and the losses incurred as the energy flows from the inverter to the wheels during driving. This energy distribution is calculated by combining multi domain models - electrical, thermal and energy loss. The electric model comprises of behavior of various components like motor, motor controller, inverter and mechanical components. Energy Loss model computes the energy loss due to heat generation in motor and inverter. The thermal model calculates the temperature of Radiator, Inverter and Motor. This integrated approach provides a better insight into the dynamic behavior of the vehicle. The results generated by the model created in MATLAB/SIMULINK environment are validated with the data available in the open literature of electric vehicles.
