Abstract: The present invention relates to an apparatus and a method capable of calculating insulation resistances and parasitic capacitances of a battery outside the battery. In the present invention, when a positive electrode connector and a negative electrode connector are coupled to a positive electrode terminal and a negative electrode terminal of the battery, respectively, and a ground connector is coupled to a case of the battery, even though the battery is positioned inside a chamber in order to perform a temperature test or the like of the battery, the insulation resistances and the parasitic capacitances of the battery may be calculated without needing to move the battery to the outside of the chamber. Accordingly, the insulation resistances and the parasitic capacitances of the battery may be conveniently calculated.
