The modeling and simulation of vehicles is an essential stage in the design process. Early design stages focus of energy-modeling, where many component dynamics are ignored and the models only compute the energy flow through the models. This allows for quick simulations and changing of component parameters, but as the design process progresses, a need for more detailed models arises. This thesis focuses on modeling and simulations of subsystems that are unique to hybrid electric vehicles, the battery, electric machine, and inverter. Battery modeling was divided into three subsystems, electrical, thermal and aging. Electrical models predict the battery voltage and state of charge. Thermal models predict the battery temperature. Aging models predict the loss in capacity and increase in resistance. The different combinations of battery, electric machine, and inverter models were simulated using a vehicle simulator of a wheel loader. The differences in fuel consumption, simulation time, battery SOC and battery capacity loss were analyzed and compared. The causes of the differences were determined, and the impact of each model fidelity was systematically and objectively evaluated.
