Modeling and simulation of power train system for extended-range electric vehicle using bond graphs

Abstract

Because the power train system of Extended-Range Electric Vehicle is a complicated multi-domain engineering system, a unified approach named Bond Graph has been used. The important drive components, especially battery, electric machine, wheel and Range Extender unit are modeled. The complex interactions among the components are taken into account in a complete multi-domain model. Once the power train system models have been developed, the dynamic behaviour of E-REVs is simulated under selected various driving cycles using rule-based energy management strategy. As important conclusion, the bond graph method has once again demonstrated its great potential for modeling technical systems with multi-domain physical fields. According to the simulation results, the significant benefits of E-REVs for the fuel reduction, emissions output and energy efficiency are proved. © 2013 Springer-Verlag.
