While construction is easily applied to a line, a main route and a charge route can always be managed so as to accommodate a fixed number of vehicles without delaying conveyance along the main route even if the number of fully-charged AGVs (automated guided vehicles) is large or zero, whereby smooth operation of the line is not hampered. A method for managing charge of a plurality of battery-driven AGVs circulating on the main route provided with an automatic charge station includes: a first step of detecting, using an AGV, a marker for battery voltage check provided on a main route to measure the voltage of a battery of the AGV; a second step of changing the route of the AGV to advance it into a charge route provided in an automatic charge station, stopping the AGV in a charging position, and charging the battery automatically by using an automatic charger, if the measured battery voltage has lowered to a level requiring charging; and a third step of conveying the AGV that has been automatically charged to a standby place provided in the automatic charge station to make the AGV stand by at the standby place, and restoring the AGV with charged battery that is waiting at the standby place back to the main route.
