Analysis of plug-in hybrid electric vehicles utility factors using GPS-based longitudinal travel data
If charged at home only, using vehicles DVMT yields good approximations of UFs. UFs based on vehicles DVMT may be slightly underestimated for small CD-range PHEVs. UFs are not sensitive to the fluctuations of the gasoline price and charging time. UFs based on weekends trips are smaller than those based on weekdays trips. Workplace charging opportunities improve UFs largely for small CD-range PHEVs.
