Abstract
An apparatus and method for diagnosing an insulation resistance measurement circuit, and more particularly an insulation resistance measurement circuit of a battery cell or a battery module. When diagnosing the state of the insulation resistance measurement circuit, since the voltage ratio based on the measured voltage value of the battery module and the estimated voltage value is used, there is an advantage that the state of the insulation resistance measurement circuit may be diagnosed more diversely and accurately.
