Publication number: 20190009683Abstract: Each time the charging of an electric vehicle is executed at a charging station, charging information is acquired which is information on a charged capacity by one charging or a time required for one charging, and identification information of the electric vehicle is acquired. Each charging time, the acquired charging information and the acquired identification information are stored in an information storage unit so that they are associated with each other. The identification information of an electric vehicle is acquired which is waiting for charging at a charging station as a calculation object for which a charging wait time is calculated. The charging information corresponding to the acquired identification information of the electric vehicle waiting for charging is extracted from the stored charging information. The charging wait time at the charging station as the calculation object is calculated on the basis of the extracted charging information.Type: ApplicationFiled: November 28, 2016Publication date: January 10, 2019Inventors: Haruyuki Saito, Takeshi Tsuda
