Hybrid Electrical Vehicle (HEV) fuel economy highly depends on power allocation between the different power sources — engine and fuel cell — and the energy storage system(s). A generic global optimization algorithm has been developed to minimize fuel consumption by optimizing the powertrain power flows. This algorithm was applied on a Fuel Cell Hybrid Vehicle, and results were generated for sev...

This paper presents Neural Network (NN) model of Polymer Electrolyte Membran (PEM) Fuel Cell for electric vehicle. The NN model simplifies the conventional model that considered thermodynamics, electrochemistry, hydrodynamics and mass transfer theory. The NN has a multilayer feed forward network structure and is trained using a back propagation learning rule. The NN model is used to predict the...

Fuel cell power for locomotives combines the environmental benefits of a catenaryelectric locomotive with the higher overall energy efficiency and lower infrastructure costs of a diesel-electric. A North American consortium, a public-private partnership, is developing a prototype hydrogen-fueled fuel cell-battery hybrid switcher locomotive for urban and military-base rail applications. Switcher...

This paper describes a virtual prototype of a PEMFC based Hybrid Electrical Military Vehicle developed within the Virtual Test Bed (VTB) environment. The VTB is software for modeling, simulation, and virtual prototyping of multi-disciplinary systems. Several of the main models used in the vehicle system especially the fuel cell model are described, and then a system-level model of a High Mobili...

This paper describes the evaluation of fuel optimal trajectories of a fuel cell powered vehicle along a given route. The optimization is based on the theory of Optimal Control, which has been applied by means of a control-oriented model developed for this purpose. The latter is a reduced complexity version of a physical model of the fuel cell vehicle, whose derivation is presented in the paper....

This paper investigates the opportunities for improving truck fuel economy through the use of a Fuel Cell Auxiliary Power Unit (FC APU) for silent watch, as well as for powering electrified engine accessories during driving. The particular vehicle selected as the platform for this study is a prototype of the Family of Medium Tactical Vehicles (FMTV) capable of carrying a 5 ton payload. Peak sta...

A hybrid electric vehicle (HEV) has two types of energy storage units, electricity and fuel. Electricity means that a battery (sometimes assisted by ultracaps) is used to store the energy, and that an electromotor (from now on called motor) will be used as traction motor. Fuel means that a tank is required, and that an Internal Combustion Engine (ICE, from now on called engine) is used to gener...
