To provide a charge control method of an electric vehicle, in which a charging efficiency is improved, and to provide a charge control device.SOLUTION: A charge control method of an electric vehicle is provided which enables charging of a plurality of electric vehicle by a plurality of charging ports. The charge control method includes steps of: acquiring battery information of each charge-target vehicle and a charging completion schedule time of a battery; and estimating a charging power upper limit value of each charge target vehicle on the basis of the battery information. The multiport charging device determines a distribution of a power output against each charge target vehicle on the basis of the charging completion schedule time of each charge target vehicle, and an output upper limit value of the charging power upper limit value and the multiport charging device. On the basis of the distribution of power, the presence/absence of a charging incomplete vehicle predicted that a charging is not completed until the charging completion schedule time is determined. When there is the charging incomplete vehicle, temperature of the battery of the vehicle is adjusted, the charging power upper limit value is increased, and a charging is performed within a range in which the output upper limit value of the multiport charging device does not exceeds.SELECTED DRAWING: Figure 3
【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、各充電対象車両のバッテリ情報と、バッテリの充電完了予定時間を取得し、バッテリ情報に基づき、各充電対象車両の充電電力上限値を推定する。そして、各充電対象車両の充電完了予定時間、充電電力上限値及びマルチポート充電器の出力上限値に基づき、マルチポート充電器が各充電対象車両に対して出力する電力の配分を決定する。また、電力の配分に基づき、充電完了予定時間までに充電を完了できないと予測される充電未完了車両の有無を判断し、充電未完了車両がある場合、当該車両のバッテリを温調し、充電電力上限値を上昇させて、マルチポート充電器の出力上限値を超えない範囲で充電を行う。【選択図】図3
