Abstract

This paper investigates the travel and charging choices of electric car users who also own a conventional-fuel vehicle. While travel behavior impacts on charging decisions have been explored in earlier studies, studies have excluded the possibility of shifting to conventional fuel vehicles by electric car users. In addition, the effects of the time spent at destinations on charging choices are also unexplored in travel behavior literature. Using a stated choice data collected in New Delhi, India, the study estimates a nested integrated choice and latent variable model to assess individuals’ choices among ‘travel according to the tour plan without charging the EV, ‘travel according to the tour plan with charging the EV’ and ‘complete the tour by shifting to conventional-fuel vehicles’. The study finds that increased tour distance leads to the choice of conventional fuel vehicle over the electric car. Besides, participation in a work tour and trip chain complexity positively affects choice of conventional fuel vehicles. While a higher initial SoC leads to decreased preferences for completing a tour on electric car with charging and shifting to conventional fuel vehicles. Overall, the study finds that travel behavior influences charging choices and travel decisions, E-car users still value conventional-fuel vehicles in accomplishing their travel patterns if E-car attributes are unfavorable.
