Abstract

A method for detecting an insulation defect in a battery may be provided. The method for detecting insulation defect includes measuring a first voltage corresponding to a voltage of a positive terminal of a battery rackduring a first duration; measuring a second voltage corresponding to a voltage of the positive terminal of the battery rack and a third voltage corresponding to a voltage of a negative terminal of the battery rack, respectively, during a second duration; measuring a fourth voltage corresponding to a voltage of the negative terminal of the battery rack during a third duration; measuring an insulation resistance value of the battery rack based on the first voltage and the fourth voltage; and determining whether the battery rack has the insulation defect based on the insulation resistance value of the battery rack.
