* DC - Study: Hybrid delivery vans show nearly 20 percent higher fuel economy
Washington,DC,USA -NREL (PR) -September 28, 2012: -- The U.S. Department of Energy's (DOE)’s National Renewable Energy Laboratory (NREL) recently completed a performance evaluation report that showed significant fuel economy benefits of hybrid electric delivery vans compared to similar conventional vans... The new NREL report — Eighteen-Month Final Evaluation of UPS Second Generation Diesel Hybrid Electric Delivery Vans— details the impact of hybridization on fuel economy and performance and identifies the conditions under which the hybrids offer maximum fuel savings... The hybrid vans feature hybrid propulsion systems: 44 kilowatt electric motors, lithium-ion batteries and regenerative braking that captures energy normally lost during braking to power the electric motor. The comparable conventional vans were approximately the same age and were operated in similar conditions out of the same facility. The two vehicle groups switched route assignments during the study period to provide a balanced review of the vans on the same route... These evaluations are part of the Advanced Vehicle Testing Activity, which supports the Energy Department’s Office of Energy Efficiency and Renewable Energy...
