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 |
