When an unmanned transporting vehicle 1 powered by a secondary battery 25 is caused by a battery controlling system to stop at a charging position 3a where a charger 3 is installed, a feeding terminal 41 at the charger 3 side is connected to a receiving terminal 16 at the unmanned transporting vehicle side to perform the charging. A controlling means 50 stops charging or discharging in compliance with an improper charging and discharging environment that is not programmed due to unpredictable cases including the time when an emergency stop is operated by a person at the charger 3 side during the charging or when the charging is not finished by the time when a given period of time has elapsed from the start of the charging at the charger 3 side. Simultaneously, the purpose above is achieved by disconnecting the feeding terminal 41 from the receiving one 16.
