Modeling and Practical Energy Management Control Design for Fuel Cell Hybrid Passenger Bus

摘要

The modeling and design of an effective and practically implementable supervisory energy management system for a hybrid fuel cell/battery-powered passenger bus is discussed in this research. Petroleum usage and greenhouse gas emissions are leading factors of concern in the transportation sector and it is critical to find alternative methods for vehicle propulsion. These factors have led to tremendous amounts of research being conducted to increase fuel economy in today's vehicles. Proton Exchange Membrane (PEM) fuel cell systems are viable possibilities for energy converters due to their high efficiencies and zero emissions. It has been shown that the benefits of PEM fuel cell systems can be greatly improved when used in conjunction with another power source such as a battery. The Center for Automotive Research (CAR) at The Ohio State University (OSU) was invited to act as a sub-contractor to the DesignLine Corporation through an ongoing award from the National Fuel Cell Bus Program (NFCBP) by aiding in the development of a high fidelity energy-based model of a hybrid fuel cell bus proposed and developed by DesignLine and to assist in the design of the supervisory energy management for the bus.
