To provide a charge control method and a charge control device of an electric vehicle with improved charging efficiency.SOLUTION: There is provided a charging control method of an electric vehicle in a multiport charger which can charge batteries of a plurality of electric vehicles by a plurality of charging ports. The charging control method calculates charge power required for a charge target vehicle on the basis of departure scheduled time set to the charge target vehicle, and determines whether or not the charge power required for the charge target vehicle can be supplied on the basis of an output upper limit value as an upper limit value of power which can be output by the multiport charger. When the required charge power cannot be supplied, power is discharged from other vehicle which is under charge or whose charge is completed to supply discharged power and output power from the multiport charger to the charge target vehicle as the charge power. In addition, discharge is executed within a range of the output power which can be discharged to be calculated on the basis of departure scheduled time of a discharge vehicle from which power is discharged.SELECTED DRAWING: Figure 8
【課題】充電効率が向上した電動車両の充電制御方法及び充電制御装置を提供する。【解決手段】複数の充電ポートにより、複数の電動車両のバッテリを充電可能なマルチポート充電器における電動車両の充電制御方法が提供される。この充電制御方法は、充電対象車両に設定された出発予定時間に基づき、当該充電対象車両に必要な充電電力を算出し、マルチポート充電器が出力可能な電力の上限値である出力上限値に基づき、充電対象車両に必要な充電電力を供給可能か否かを判断する。必要な充電電力を供給できない場合、充電中または充電を完了した他車両から放電して、当該放電電力とマルチポート充電器からの出力電力とを充電対象車両に充電電力として供給する。また、当該放電は、放電を行う放電車両の出発予定時間に基づき算出される放電可能な出力電力の範囲内で実行される。【選択図】図8
