Abstract
In this paper, we examine the effect of non-policy factors, such as temperature and slope, on the diffusion of Electric Vehicle (EV) by conducting multiple regression analysis. Using an air conditioner and steep slope, for example, increase electricity consumption and decrease the cruising range of EV, which is one of the key factors of the EV diffusion. Therefore, we alternately used some indicators representing temperature and angle of slope as explanatory variable to investigate that effect on the diffusion of EV. The multiple regression analysis result shows that low temperature hinders the EV diffusion and does not show that angle of slope statistically have an effect on it. Thus, we confirmed that it was significant to consider the effect of temperature on the EV diffusion, for example, when policy makers try to introduce a subsidy.
