<p><P>PROBLEM TO BE SOLVED: To provide a method for controlling the charging/discharging of a secondary battery for an automated guided vehicle, capable of correctly determining refresh charging/discharging timing to minimize a charging/discharging frequency. <P>SOLUTION: This method for controlling the charging/discharging of the secondary battery for the automated guided vehicle includes a first discharging step, a voltage measuring step and a charging step. In the first discharging step, the secondary battery drives the automated guided vehicle to discharge a prescribed electric amount. In the voltage measuring step, a voltage of the secondary battery at a discharge ending time is measured when the first discharging step ends. In the charging step, when a voltage at the discharge ending time is higher than a set lower-limit voltage, a first charging step is performed to incompletely charge the secondary battery by a first charging current value, and when a voltage at the discharge ending time is lower than the set lower-limit voltage, a second charging step is performed to completely discharge the secondary battery and continuously completely charge the secondary battery by a second charging current value which is smaller than the first charging current value. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
