PROBLEM TO BE SOLVED: To provide a conveyance system of an unmanned carrier, which can prolong the service life of a battery mounted on the unmanned carrier.SOLUTION: A conveyance system of an unmanned carrier comprises a capacitor 80 arranged such that the regenerative current generated when braking with a travel motor 33 can be branched to the same, a switch 81 for branching the regenerative current to the capacitor 80, and an on-vehicle computer 37. The on-vehicle computer 37, before regeneration of the unmanned carrier, calculates the maximum current during the regeneration and the charging rate of a battery during the regeneration, determines whether or not at least one of the calculated maximum current during the regeneration and the calculated charging rate of the battery during the regeneration is larger than a threshold, and when the same is larger, previously switches the switch 81 before the regeneration to branch the regenerative current to the capacitor 80.SELECTED DRAWING: Figure 2
【課題】無人搬送車に搭載したバッテリの長寿命化を図ることができる無人搬送車の搬送システムを提供する。【解決手段】走行モータ33で制動する時に発生する回生電流を分岐可能に配したキャパシタ80と、回生電流をキャパシタ80に分岐させるためのスイッチ81と、車載コンピュータ37とを備える。車載コンピュータ37は、無人搬送車の回生前に、回生時の最大電流および回生時のバッテリの充電率を算出するとともに、算出された回生時の最大電流および回生時のバッテリの充電率の少なくとも一方が閾値より大きいか否か判定して大きいと回生前に回生電流をキャパシタ80に分岐させるべくスイッチ81を予め切り替える。【選択図】図2
