Abstract

By considering the symbiosis between rest behavior with charging behavior during intercity traveling, the inconvenience of battery electric vehicles (BEVs) confined by the battery capacity can be relieved. This paper proposed a quantitative analysis method for revealing this phenomenon from an accessibility perspective. This proposed method involved a calculation model of intercity travel time for electric vehicle by considering the current configuration of electric vehicle charging facilities and energy consumption with travel speed. Based on the highway network and charging pile network in Beijing-Tianjin-Hebei region, a case study has been analyzed to verify the feasibility of the model. The results show that the accessibility performance of BEVs and fuel vehicles is close in Beijing Tianjin Hebei region, which has relatively perfect charging facilities. And by joint the charging behavior and rest behavior, there is almost no difference between BEV models with a large range and advanced charging technology and fuel vehicles in intercity travel. In addition, the charging facilities along the expressway in the region can basically satisfy the experience of intercity travel for BEVs, and further increasing the number of charging stations cannot significantly improve the accessibility of electric vehicles.
