To execute charging within a range of an allowable current of each of charger units and power supply lines in charging batteries for a plurality of electrically-driven autonomous mobile bodies with one of the charger units by aligning the plurality of electrically-driven autonomous mobile bodies in a series state and electrically connecting the charger units with the plurality of electrically-driven autonomous mobile bodies..SOLUTION: In charging batteries for a plurality of electrically-driven autonomous mobile bodies, each of the electrically-driven autonomous mobile bodies transmits charging state information of the batteries for the electrically-driven autonomous mobile bodies of their own. A controller controls switching between a charging state and a non-charging state of the battery for each of the electrically-driven autonomous mobile bodies on the basis of the charging state information of the battery for each of the electrically-driven autonomous mobile bodies, so that a total sum of currents running through the battery of each of the electrically-driven autonomous mobile bodies does not exceed an allowable current of each of charger units and power supply lines.SELECTED DRAWING: Figure 10
【課題】複数の電動自立移動体を直列状態に整列させ、充電器ユニットと複数の電動自立移動体とを電気的に接続して、1つの充電器ユニットで複数の電動自立移動体のバッテリを充電する場合において、充電器ユニット及び電力供給ラインの許容電流の範囲内で充電を行うこと。【解決手段】複数の電動自立移動体のバッテリを充電するに当たり、各電動自立移動体は、自身の電動自立移動体のバッテリの充電状態を示す充電状態情報を発信する。制御器は、各電動自立移動体のバッテリに流れる電流の総和が、充電器ユニット及び電力供給ラインの許容電流を超えないように、各電動自立移動体のバッテリの充電状態情報を基に、各電動自立移動体のバッテリの充電状態と非充電状態とを切替制御する。【選択図】図10
