description An apparatus for diagnosing a state of a battery according to an embodiment of the present disclosure includes a profile obtaining unit configured to obtain a plurality of differential profiles representing a corresponding relationship between a differential capacity representing a change rate of a capacity of a battery with respect to a voltage of the battery and the voltage; a peak determining unit configured to determine a target peak located in a predetermined voltage section in each of the plurality of differential profiles; and a state diagnosing unit configured to compare the voltage of a plurality of target peaks determined by the peak determining unit with a voltage of a reference peak preset to correspond to each of the plurality of target peaks, and diagnose a state of the battery based on the voltage comparison result.
