Abstract
With increasing oil price and mounting environment concerns, cleaner and sustainable
energy solutions have been demanded. At present transportation constitutes a large
portion of the energy consumed and pollution created. In this work, two hybrid
vehicle powertrain technologies were studied, a fuel cell - battery hybrid and two
internal combustion engine - battery/ultracapacitor hybrids. Powertrain performance
models were built to simulate the performance of these new designs, and to assess the
feasibility of a fuel cell hybrid power backup system for a special type of vehicles,
elevators in high-rise buildings, using the ADvanced VehIcle SimulatOR (ADVISOR)
first. The model was then applied to evaluate the two-mode hybrid powertrain for
more common vehicles - commercial trucks, showing potential fuel consumption
reduction. To improve modeling accuracy, a new and more flexible tool for modeling
multi-physics systems, Modelica/Dymola, was used to carry out the modeling and
analysis of next generation hybrid electric vehicles, exploring the potentials of new
hybrid powertrain architectures and energy storage system designs. The study forms
the foundation for further research and developments.
