To provide a charging/discharging system for an electric vehicle capable of performing real-time charging/discharging control by making an amount of charging/discharging of the electric vehicle to follow an instruction of the amount of charging/discharging from an external power network at a current time.SOLUTION: A charging/discharging system for an electric vehicle performs charging/discharging control by electrically connecting batteries of a plurality of electric vehicles relative to an external power network. The charging/discharging system adds a correction value obtained from a prediction value of an amount of charging/discharging before a predetermined time than a current time and an actual measurement value of the amount of charging/discharging before a predetermined time than the current time to a prediction value of the amount of charging/discharging of the electric vehicle based on past parking rate data at the current time to obtain an actual measurement prediction value of the amount of charging/discharging at the current time and instructs the amount of charging/discharging corrected by the actual measurement prediction value to the plurality of electric vehicles.SELECTED DRAWING: Figure 1
