Future massive introduction of renewable power generation can cause a large amount of surplus power. The surplus power can be utilized effectively to charge Electric Vehicles (EVs) significantly if the timing of charging demand can be shifted to follow the change in renewable power supply. In order to assess the feasible EV charging using surplus renewable power, this study proposes a model for EV users' charging decisions according to SOC and cumulative irradiance, in which individual EV utilization patterns are taken into account based on a road traffic census. Then, this study evaluates the effect of a Charging Promotion Time Zone (CPTZ) depending on the daily cumulative irradiance to increase EV charging by surplus power. The result for the Chubu area, which is in the middle of the main island in Japan, shows that the proposed CPTZ increases EV charging with renewable power by about 14% without compromising the convenience of EVs as vehicles.
