Abstract
The present invention relates to an insulation resistance measuring system and device which calculate resistance values of the positive electrode insulation resistance and the negative electrode insulation resistance by using convergence values of the first voltage and the second voltage, in order to measure the positive electrode insulation resistance and the negative electrode insulation resistance connected to both terminals of a battery pack with a capacitor, respectively.
