Abstract

Disclosed is a battery diagnosing apparatus and a battery diagnosing method. The battery diagnosing apparatus includes a data obtaining unit configured to obtain a first profile representing a capacity-voltage relationship of a battery cell containing at least two kinds of active materials, and a processor configured to generate a plurality of comparison profiles based on a plurality of electrode profiles included in an electrode profile map. The processor is configured to select, as a second profile, one comparison profile from the plurality of comparison profiles by comparing each of the plurality of comparison profiles with the first profile. The processor is configured to determine at least one diagnostic factor representing a degradation state of the battery cell based on the second profile.
