Electric Motor Sizing for an Automotive Power Train to Reach Thermal Engine Powered Vehicles Performance Using an Inverse Bond Graph-Based Method

摘要

This paper aims at determining suitable electric motor characteristics for an automotive power train in order to reach internal combustion engine powered vehicles performance by means of an inverse bond graph-based inverse method using the concept of bicausality. The methodology is presented first and applied to an automotive electric power train. A direct power train model is exposed and inverse models are deduced according to different kinds of specifications (steady state or dynamic criteria). Ideal electric motor maximum torque and power characteristics are presented and finally simulations results are given and discussed.
