The National Renewable Energy Laboratorys (NREL) Fleet Test and Evaluation team evaluated the 12-month, in-service performance of six Class 4 hybrid electric delivery vans--fueled by regular diesel--and six comparable conventional diesel vans operated by the United Parcel Service (UPS). In addition, the fuel economy and emissions of one Class 6 UPS hybrid electric delivery van and one comparable conventional diesel van were tested on a laboratory chassis dynamometer. All the hybrid vans tested were equipped with the same parallel hybrid system manufactured by Eaton Corp., including a synchronous brushless, permanent magnet motor (26-kW continuous power, 44-kW peak power) and lithium-ion batteries that provide 340 VDC and 1.8 kWh of energy storage. UPS is satisfied with its 50 prototype hybrid vans and ordered 200 more in 2009.
