The potential for a BEV in the two-car household

Abstract

An optimization model was developed to estimate the potential for a BEV, when replacing one of the conventional cars, to viably contribute to the performance of the driving in the households. It uses data from 1 to 3 months of simultaneous GPS logging of the movement patterns for both cars in 64 commuting 2-car Swedish households. The results show that the BEV can potentially roughly double the driving and still decrease the unfulfilled driving in the household with a flexible car use strategy compared to a BEV substituting the 2nd car only, turning the BEV economics into a TCO gain.
