Coca-Cola Refreshments Class 8 Diesel Electric Hybrid Tractor Evaluation: 13-Month.

摘要

This 13-month evaluation is part of a series of evaluations by the U.S. Department of Energy (DOE). Using an established and documented evaluation protocol, DOE through the National Renewable Energy Laboratory (NREL) has been tracking and evaluating new propulsion systems in transit buses and trucks for more than 10 years. The DOE/NREL vehicle evaluations are a part of the Advanced Vehicle Testing Activity (AVTA), which supports DOE's Vehicle Technologies Program. The role of AVTA is to bridge the gap between research and development and the commercial availability of advanced vehicle technologies that reduce petroleum use in the United States and improve air quality. The main objective of AVTA projects is to provide comprehensive, unbiased evaluations of advanced vehicle technologies in commercial use. Data are collected and analyzed for operation, maintenance, performance, costs, and emissions characteristics of both advanced-technology fleets and comparable conventional-technology fleets that are operating at the same site. AVTA evaluations enable fleet owners and operators to make informed vehicle-purchasing decisions. This report focuses on a parallel hybrid-electric diesel tractor trailer propulsion system currently being operated by Coca-Cola Refreshments (CCR). The hybrid propulsion system is an alternative to the standard diesel system and allows for increased fuel economy, which ultimately reduces petroleum use. This study highlights the importance of route selection and vehicle placement to optimize hybrid advantage. Hybrid advantage is optimized in routes which include high start-stop density.
