CHARGING CONTROL DEVICE FOR MAGNETIC LEVITATION CONVEYANCE SYSTEM

摘要

PURPOSE: To eliminate a hindrance to the operation of a conveyance system owing to the poor utilization efficiency of a battery which gives rise to trouble in the periodic charging of an on-vehicle battery under time control and also owing to the continuous use of a deteriorated battery in a magnetic levitation conveyance system. CONSTITUTION: A device 2 for performing the charging control of an on-vehicle battery A is constituted of a means for controlling the charging period of the battery, a means for monitoring the individual charging voltage of the battery at the time of charging, a means for comparing the monitored voltage with a predetermined voltage pattern and a means for determining unusual charging when a reach voltage at the time of the completion of charging is lower than a predetermined voltage to transmit an abnormal signal to an operation control system and therefore the deterioration of a battery can be surely detected and the above-mentioned trouble can be eliminated by rationalizing the replacement period of a deteriorated battery.
