Abstract
A battery diagnosis device according to an embodiment disclosed in this document may include an acquisition unit that acquires pack data related to a state of a battery pack and cell data related to a state of a plurality of battery cells included in the battery pack, an identification unit that identifies, based on the pack data, a first OCV section in which a voltage standard score (Z-Score) difference between the plurality of battery cells decreases as an open circuit voltage (OCV) of the battery pack increases and a second OCV section in which the voltage standard score difference between the plurality of battery cells increases as the OCV of the battery pack increases, an extraction unit that extracts, based on the cell data, a diagnostic feature value from voltage standard scores of the plurality of battery cells corresponding to each of the first OCV section and the second OCV section and a diagnosis unit that diagnoses an abnormality of the battery pack based on the extracted diagnostic feature value.
