Charge management system for automatic guided vehicle and charge management method for automatic guided vehicle

摘要

A battery charging management system for an automated guided vehicle that travels in an unpiloted manner by using a battery as a driving power source and performs a charging operation for the battery using a battery charger provided in a charging station, comprises a charge/discharge monitoring part that monitors a charge/discharge amount of the battery, a charging needlessness threshold voltage setting part that sets a charging needlessness threshold voltage for the battery, and a charging control part that performs the charging operation for the battery using the battery charger when it is determined that a voltage of the battery of the automated guided vehicle arriving at the charging station is lower than the charging needlessness threshold voltage set by the charging needlessness threshold voltage setting part. The charging needlessness threshold voltage setting part is configured to lower the charging needlessness threshold voltage during a particularly set time period.
