EDLC monitoring device

The present invention monitors the voltage of each cell constituting the EDLC EDLC proposes a monitoring apparatus for real-time monitoring the voltage of each cell in the cell equal controller. To this end, the present invention relates to a EDLC monitoring device for the uniform control of each EDLC constituting the EDLC (Electric Double Layer Capacitor) pack, a primary side and for the input stage, the secondary side of the transformer forming the output stage, the first side and input when the residual current induction coil and a switch which connects the power source to the switch, the primary-side ends to regulate be opened in a short-circuited state, the detection of the open voltage across the switch both ends, and the winding ratio and the open voltage and the input voltage of the transformer multiplying the difference value calculated by the voltage of the output stage, and can comprise voltage EDLC prediction unit for determining an EDLC voltage based on this.
