Designers cannot build and test prototypes for all the possible vehicle configurations prior to initiation of production due to time and cost constraints. Therefore, developing advanced vehicle propulsion systems requires accurate and flexible modeling methods or tools for feasibility analysis ahead of building prototypes. In this chapter, methodologies involved in accurate modeling of the main components existing in conventional, pure electric, and hybrid electric vehicle propulsion systems are discussed. It should be noted that the modeling representations established here for energy converters (e.g., internal combustion engine, fuel cell, etc.), energy storage systems (ESS, e.g., battery, ultracapacitor, flywheel, etc.), electric machines (i.e., generator and traction motor) and mechanical devices (e.g., gearbox, continuously variable transmission, etc.) can be used individually or collectively for various types of vehicle system configurations, as well as for other propulsion systems. Detailed parameters, mathematical expressions, and characteristics analysis provided in this chapter should be useful for readers to set up effective models in simulation research, early design phase or operation performance analysis of vehicle propulsion systems.
