Abstract
Electric Vehicle (EV) is coming up as an eco-friendly next-generation vehicle. A lot of companies release plans to sell EV, and then it is expected that EV becomes a means of transportation in daily life in the near future. This study aims to pose an optimal routing problem of EV considering gradients (slopes) of roads. An optimal routing problem of EV differs from that of conventional cars, because electricity consumption and cruising range vary with inner states (battery performance and weight) of EV and the use of regenerative brake. In this study, a calculation model of electricity consumption of EV considering gradients is proposed. The influence of road gradient on an optimal routing of EV is also evaluated.
