The research presented in this paper is part of a broad study that investigated the implications of Hybrid Electric Vehicles (HEVs) and Plug-in Electric Hybrid Vehicles (PHEVs) in terms of mobile source emissions which were used to develop an approach for incorporating EVs into regional emissions inventory procedures. The main objective of the work presented in this paper was to characterize the tailpipe emissions of HEVs and PHEVs. The research team focused on the Texas context, specifically with regards to practices of conducting regional emissions inventories using the United States Environmental Protection Agency’s (EPA) MOVES model. Researchers conducted an extensive vehicle activity data collection exercise from a sample of EVs in major Texas metropolitan areas. These data was used to develop more than 60 representative Texas- specific HEV and PHEV drive schedules. In-use emissions testing of four HEVs and four PHEVs was then conducted using a portable emissions measurements system and engine control unit loggers to obtain operating-mode-based emissions and electricity consumption rates, which were combined with the drive schedules to obtain distance-based emissions rates for each HEV and PHEV by speed bin and road class.

This paper was sponsored by TRB committee ADC80 Standing Committee on Alternative Transportation Fuels and Technologies.
