Nagasaki prefecture, as one of eight EV&PHV towns, is now promoting “Nagasaki EV&ITS project” to construct practical penetration model of EV and PHV (Plug-in Hybrid Vehicle) especially in isolated islands. In this project, Goto islands were selected as the first subject area and “driving tour of the future,” which enables tourists to drive around the islands ecologically, is now being constructed, utilizing their tourist attractions including churches registered in the candidate list of world heritages. On the first step of the project, 100 EVs and 2 PHVs with ITS onboard devices installed and 15 quick chargers on 8 spots were introduced. These EVs and PHVs are mainly utilized as rent-a-car for tourists and obtain plenty of uses by general people with high frequency. Those uses revealed numbers of practical problems and their solutions. In this paper, those results of such practical penetration are reported.
