Abstract
A battery diagnosing apparatus includes a profile generating unit configured to generate a differential profile representing a corresponding relationship between a voltage of a battery and a differential capacity for the voltage of the battery and a control unit configured to receive the differential profile from the profile generating unit, determine a target peak in the differential profile, determine a behavior pattern of the target peak based on a reference peak included in a preset reference profile, and diagnose a state of a negative electrode of the battery by comparing the behavior pattern determined for the target peak with a plurality of preset behavior types.
