CHARGING MANAGEMENT SYSTEM FOR UNPILOTED CONVEYANCE VEHICLES

A system for managing charging of each of a plurality of automated guided vehicles that travels on an orbiting route in an unmanned manner using a battery mounted thereon as a driving source, in which the battery is charged at a charging station installed at a predetermined position on the orbiting route, includes: an after-charging voltage recording unit for recording a voltage after charging at the charging station for each of the automated guided vehicles; a charge priority setting unit for setting up charge priority of each of the automated guided vehicles on the basis of voltage values of voltages after charging recorded in the after-charging voltage recording unit; and a charging target value setting unit for setting up a charging target value of each of the automated guided vehicles on the basis of the charge priorities set up by the charge priority setting unit.
