Abstract
A battery diagnosing apparatus includes a profile generating unit configured to obtain a battery profile representing a corresponding relationship between voltage and capacity of a battery, and generate a differential profile representing a corresponding relationship between the voltage and a differential capacity for the voltage based on the obtained battery profile, and a control unit configured to receive the differential profile from the profile generating unit, determine a target peak in the differential profile, compare voltages of the determined target peak and a criterion peak of a criterion profile preset for the battery, and judge whether a side reaction occurs in the battery based on the comparison result.
