The present invention relates to a charge current control device of an EDLC in an electric car for a clean-room distribution transfer device. The charge current control device of an EDLC in an electric car for a clean-room distribution transfer device which comprises a power supply line supplying main electricity in ordinary times and supplies emergency electricity in an emergency as being classified into the ordinary time and the emergency according to a predetermined criterion, includes: an MCU (16) which controls a charge current value at a gate of a semiconductor switch device Q3 by a proportional-integral-derivative (PID) control method as turning on a semiconductor switch device Q1 or a semiconductor switch device Q2 and slowly increasing a PWM duty ratio from 0%, if it is checked that electricity is supplied to a main power control input part (11) or an emergency power control input part (13); an electric car control part (19) for controlling a motor (20) driving the electric car; a control device power supply part (21) for supplying electricity to each control part; and the EDLC (18) which is a battery of the electric car. The MCU (16) detects exhaustion of the EDLC module and stops running of the electric car if the charged amount is less than a minimum reference value, and charges the EDLC module by making a charging port come in contact with a corresponding power supply line by a main docking solenoid or an emergency docking solenoid and then runs the electric car after making the charging port come in non-contact with the power supply line. |
