Book Description
A government, industry and academic cooperative has developed a Hybrid Electric Transit Bus (HETB). Goals of the program include doubling the fuel economy of city transit buses currently in service, and reducing emissions to one-tenth of EPA standards. Unique aspects of the vehicle's power system include the use of ultra-capacitors for the energy storage system and the planned use of a natural gas fueled turbogenerator, to be developed from a small jet engine. At over 17000 kg gross weight, this is the largest vehicle to use ultra-capacitor energy storage. A description of the HETB, the results of performance testing, and future vehicle development plans are the subject of this report.Brown, Jeffrey C. and Eichenberg, Dennis J. and Thompson, William K.Glenn Research CenterELECTRIC HYBRID VEHICLES; URBAN TRANSPORTATION; ENGINE DESIGN; DESIGN ANALYSIS; PERFORMANCE TESTS; HYBRID PROPULSION; ENERGY STORAGE; CAPACITORS; NATURAL GAS; TURBOGENERATORS; FUEL CONSUMPTION; ENVIRONMENT EFFECTS; TECHNOLOGY TRANSFER; JET ENGINES

Book Description
TCRP Report 132: Assessment of Hybrid-Electric Transit Bus Technology provides decisionmaking guidelines coupled with a comprehensive life cycle cost model (LCCM) to assist transit managers in evaluating, selecting, and implementing hybrid-electric technology options for transit buses. The guidelines and the accompanying LCC model resulted from the gathering of site data coupled with a comprehensive review of both capital requirements and operating costs of hybrid-electric buses in comparison with those powered by traditional diesel engines. Information grew out of a sound, engineering-based, independent technical evaluation of the costs, performance, and reliability of hybrid-electric transit bus technology in actual service. The LCC model, contained on the accompanying CD-ROM (CRP-CD-71), allows the user to compare the total life cycle costs across several cost categories for up to 6 different "purchase scenarios." These scenarios let the user decide when the purchases will be made, the types of buses to be compared, the work load of the buses, and many other cost inputs in determining benefits and costs associated with alternative purchasing strategies.

Book Description
The NASA John H. Glenn Research Center initiated baseline testing of the EV Global E-Bike SX as an update of the state of the art in hybrid electric bicycles. The E-bike is seen as a way to reduce pollution in urban areas, reduce fossil fuel consumption, and reduce operating costs for transportation systems. The work was done under the Hybrid Power Management (HPM) Program, which includes the Hybrid Electric Transit Bus (HETB). The SX is a high performance, state of the art, ground up, hybrid electric bicycle. Unique features of the SX's 36 V power system include the use of an efficient, 400 W, electric hub motor, and a seven-speed derailleur system that permits operation as fully electric, fully pedal, or a combination of the two. Other innovative features, such as regenerative braking through ultracapacitor energy storage, are planned. Regenerative braking recovers much of the kinetic energy of the vehicle during deceleration. The E-Bike is an inexpensive approach to advance the state of the art in hybrid technology in a practical application. The project transfers space technology to terrestrial use via nontraditional partners, and provides power system data valuable for future space applications. A description of the SX, the results of performance testing, and future vehicle development plans are given in this report. The report concludes that the SX provides excellent performance, and that the implementation of ultracapacitors in the power system can provide significant performance improvements.Eichenherg, Dennis J. and Kolacz, John S. and Tavernelli, Paul F.Glenn Research CenterURBAN TRANSPORTATION; BICYCLE; PERFORMANCE TESTS; ELECTRIC HYBRID VEHICLES; BRAKING; TECHNOLOGY UTILIZATION; AEROSPACE TECHNOLOGY TRANSFER...

Book Description
This report presents an up-to-date description of emerging hybrid-electric drive technology for transit buses in the United States. The technology and its status, benefits, life-cycle costs, and deployment issues are discussed. The report is intended to provide transit agencies with information to compare the emissions and fuel economy expected from hybrid-electric transit buses with those expected from clean diesel or alternatively fueled buses.
