Abstract

Highlights: GPS data from an EV trial is used to analyse behavior in households with EV and CV. A mixed non-linear regression model for daily mileage in EV and CV is proposed. A mixed logit model for the choice between EV and CV for a journey is proposed. EV use is reduced during weekends and only EV use is affected by weather variables. EV is mainly used for short trips during morning peaks on weekdays. Abstract: The market share of battery electric vehicles (EVs) is expected to increase in the near future, but so far little is known about the actual usage of this emergent technology. Consumer preference studies have indicated that the current limitation on driving distance is important. At the same time studies on the actual use of household vehicles indicate modest requirements for daily travel. An unresolved issue is to what extent these range limitations affect daily travel in EVs. In this study, we use real electric vehicle trip data to study the distribution of daily use and types of home-based journeys where a household decides to use an electric vehicle instead of their conventional vehicle. The results show how several factors related to distance and number of necessary charging events have plausible effects on electric vehicle travel behaviour. Further, the modelling indicates that the EV alternative is mostly used for well-planned transport and that EV use will not be the same as use of the conventional vehicle in two-vehicle households.
