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

    【課題】現時刻の外部電力網からの充放電量の指示に電動車の充放電量を追従させてリアルタイムでの充放電制御を行うことができる電動車の充放電システムを提供すること。【解決手段】外部電力網に対し、複数の電動車のバッテリを電気的に接続して充放電制御を行う、電動車の充放電システムであって、充放電システムは、現時刻における過去の駐車率データに基づいた電動車の充放電量の予測値に対し、現時刻よりも所定時間前の充放電量の予測値と、現時刻よりも所定時間前の充放電量の実測値と、から求められる補正値を加味して、現時刻における充放電量の実測予測値を求め、実測予測値によって補正された充放電量の指示を、複数の電動車に対して行う。【選択図】図1
