E-lab group’s suggestion for the development of Utility Factors WLTP-09-06-rev1e Utility Factors Fleet utility factor This can reflect the electricity consumption of charge depleting mode in a specific fleet for OVC-HEVs. Individual utility factor This can reflect the usability of charge depleting mode for a set of vehicles. The choice of UFs depends on CPs’ policies. Suggestion: ・Referring standard development method (SAE J2841) of UFs ・Putting available UFs (the US, EU and Japan) in the GTR as the information for CPs who have no UFs yet.
