When developing and designing new technology for integrated vehicle systems deployment, standard cycles have long existed for chassis dynamometer testing and tuning of the system. However to this day, with recent developments and advancements in PHEV/BEV vehicle technology, no true “work day” cycles exists with which to tune and measure energy storage control and thermal management systems. To address this issues and in support of development of a range extended pickup and delivery class 6 commercial vehicle, NREL researchers in collaboration with Cummins and Argonne National Laboratory analyzed only 78,000 days of operational data captured from more than 260 vehicles operating across the United States. In total, over 2.5 million miles of real world vehicle operation were condensed into a pair of duty cycles, an 80 mile and an 100 mile cycle representative of the daily operation of US class 3-6 commercial pickup and delivery trucks. Using novel clustering methods and mileage based weighting, these composite representative cycles correspond to 85th and 90th percentiles for daily vehicle mileage traveled observed by vehicles examine. In addition to including vehicle speed vs time drive cycles, in an effort to better represent the environmental factors encountered by pickup and delivery vehicles operating across the united states, a nationally representative grade profile and key status information were also appended to the speed vs time information to produce a “work day” cycle which captures the effects of vehicle dynamics, geography, and driver behavior which can be used for future design, development, and validation of technology.
