NREL evaluates UPS hybrid-electric van performance

摘要

According to U.S. DOE National Renewable Energy Laboratory (NREL) Advanced Vehicle Testing Activity (AVTA) program manager Lee Slezak, the lab has collected and analyzed fuel economy, maintenance and other vehicle performance data from UPS's first generation hybrid diesel step delivery vans powered by an Eaton Corp. electric hybrid propulsion system.rnNREL's Fleet Test & Evaluation (FT&E) team performed a 12-month evaluation of six of these hybrid vans at a UPS location in Phoenix and concluded, "The diesel hybrid delivery vans improved the on-road fuel economy by 28.9% resulting in a 15% improvement in total cost per mile while maintaining similar reliability and operational performance as compared to conventional vehicles."
