Abstract: Traditional architectural and performance integration methods for vehicle development and validation do not address some of the new issues arising from the electrification of the drive systems. These traditional methods are developed with focus on the mechanical systems. Considering that the majority of architectural and performance issues arise at the interfaces, the complexity increases when these interfaces are made of different types such as electro-mechanical and electro-chemical. In advanced propulsion systems development and validation, these newly arising electrical and chemical interface issues need to be addressed in addition to the traditional mechanical integration tasks. Failure in addressing these issues could impede achieving performance targets and drastically alter vehicle attributes. In this paper, some of the new modelling and simulation issues arising from vehicle electrification during the development and integration of advanced propulsion systems are discussed. To demonstrate some of these issues and illustrate their impact on achieving vehicle performance targets and attributes, some cases from a hybrid bus development are presented. These cases include virtual and physical modelling for road data acquisition, battery system development and hybrid system integration.
