Claim Text:
1. A battery charging management system that manages charging operations of automated guided vehicles including a first type of automated guided vehicle that travels in an unpiloted manner by using a first type of mounted battery as a driving source and charges the first type of mounted battery using an automatic battery charger provided in a charging station and a second type of automated guided vehicle that travels in an unpiloted manner by using a second type of mounted battery as a driving source having a full charge voltage lower than a full charge voltage of the first type of mounted battery and charges the second type of mounted battery using the automatic battery charger, wherein the first type of automated guided vehicle is not provided with a controller for controlling a voltage of the first type of mounted battery during charging operations, the first type of mounted battery is charged while the voltage of the first type of mounted battery is controlled by a first battery charging controller provided in the automatic battery charger, the second type of automated guided vehicle is provided with a second battery charging controller that controls a voltage of the second type of mounted battery, the second battery charging controller performs a charging operation using the automatic battery charger for the second type of mounted battery in the charging station when the voltage of the second type of mounted battery is lower than a predetermined voltage lower than the full charge voltage of the second type of mounted battery, and a charging route of the vehicle is cut off when the voltage of the second type of mounted battery during the charging operation reaches a voltage lower than the full charge voltage of the first type of mounted battery and higher than the predetermined voltage.
