The Coordinating Research Council, Inc. (CRC) conducted a workshop during February 2005 as an initial investigation into the unique technology-independent issues associated with evaluating the cold-start and warm-up driveability of hybrid vehicles, regardless of their hardware or technology. The workshop was conducted as a joint endeavor by the CRC Performance Committee and the CRC Advanced Vehicle/Fuel/Lubricants Committee. Ten vehicles (nine hybrid and one conventional) were tested with two fuels: one a marketplace fuel from California with a nominal Driveability Index (DI) of 1100, and one containing 10 volume percent ethanol with the DI targeted at 1300. Issues investigated during this workshop included instrumentation required for evaluating hybrids, a new defueling system, the effect of the preconditioning cycle on state-ofcharge (SOC), and various maneuvers that might show promise for further investigation. A second workshop is planned for a later date when a broad spectrum of hybrid vehicles is available. This second workshop will then apply the results of this initial investigation to develop and validate a CRC hybrid test procedure using many different types of hardware and hybrid technologies with a wide range of DI fuels. |
