Modeling and validation of a hydrogen engine powered hybrid electric vehicle

This paper describes the modeling and validation of a hybrid electric vehicle powered by hydrogen internal-combustion engine. The engine was converted from a regular gasoline engine. The model of this vehicle was developed in PNGV Systems Analysis Toolkit (PSAT), which tracks engine flow and fuel usage within the vehicle powertrain and energy conversion components. The powertrain control strategy was developed and tuned in PSAT first and was then incorporated into the vehicle. The vehicle then was tested on the EPA highway driving cycle to provide data for validation of the model. Vehicle data and modeling results show good correlation at high steady-state and difference in transients.
