20. SAE Utility Factor The UF indicates the limited utility of a particular initial operating mode-for PHEVs, the CD mode. An operating mode with a very long range, for example, will have a very high utility and, thus, a UF that approaches 1.0. The UF result is for a distance R CD based upon a set in-use data collected of daily miles traveled per day of a large sample group. The UF is defined by using the assumptions that (1)the vehicle starts the day from a routinely achieved,fully charged state and (2)the vehicle is charged to said state before everyday of personal travel. The UF weighting for given R CD is applied to the CD results, and the term (1-UF) is applied the CS mode results.
