PURPOSE:To prevent a trouble during running due to insufficient charge or deterioration of a secondary battery of a magnetic levitation conveying vehicle. CONSTITUTION:A voltage detecting circuit 31 for measuring terminal voltage of a secondary battery 25 and a transmitting circuit 34 for responding the measured voltage of this voltage detecting circuit 31 to a computer 14 by a voltage confirming request signal of the computer 4 on the ground are provided in a magnetic levitation conveying vehicle provided with the secondary battery 25 for magnetic levitation. On the other hand, a charging timer T for measuring a running time of the conveying vehicle is provided in the computer 14, to correct a measured time of this charging timer T based on a voltage value, and when the timer T reaches a time up, the conveying vehicle is guided to a charge station 3 to perform charging. |
