充電要否判断モデルに基づく電気自動車の充電行動解析

―基地充電の有無と電池容量増大の影響―

The charging facilities of electric vehicles (EV) include a base charging (BC) at a garage or parking lot, a destination charging (DsC) at a reached destination, and an in-route charging which is performed on the way. As the current domestic in-route charging mostly uses a quick charger (QC), these charging facilities can be categorized into three types: QC, DsC, and BC. In this study, we clarified the characteristics of these three charging facilities and the required portrait for social infrastructure by simulating the basic charging behavior of EV. As basic data on charging characteristics of EV users, the questionnaire results from EV users (864 people) conducted in March 2017 were used. First, we decided the charging rules of QC, DsC, and BC, and set the standard for charging and running model. The result shows that the shorter the distance between QCs, the smaller the amount of electricity charged by QC per EV. This result was in a good agreement with the spread of domestic QCs and the declining trend of charged electric energy per EV. Furthermore, We investigated several manner using three charging facilities, and the results show many effects by changing the battery capacity.
