Emission reduction benefits from PHEVs
van Gijlswijk, R.N.
Road transport plays a significant role in climate change and it contributes to poor air quality, especially in densely populated areas. This is a global problem, which also requires regional solutions. Electrification of vehicles is encouraged by the European Commission for this reason. Many countries and regions, like Flanders investigate the option of stimulating new vehicle technologies to reduce emissions. The present paper examines the likely impact of plug-in hybrid electric vehicles (PHEV) in the Flemish region by combining a small-scale measurement campaign and vehicle simulations for the development of relevant emissions factors. For one and a half months, SEMS equipment were installed on three PHEVs to measure NOx and CO2 emissions, while monitoring the vehicle owners' charging behaviour. An important parameter derived from these data is the utility factor (UF), which is the ratio between driving distance in charge-depleting (CD) and charge-sustaining (CS) mode between two charge cycles.
