A battery diagnosing apparatus according to an embodiment of the present disclosure includes: a profile acquisition unit that acquires a differential profile representing a correspondence between a voltage and a differential capacity of a battery; a profile correction unit that determines a target C-rate corresponding to the differential profile, and corrects the differential profile based on an overvoltage profile corresponding to the target C-rate, thereby generating a corrected profile; and a control unit that determines a first target peak and a second target peak in the corrected profile, and diagnoses a state of the battery based on a behavior of the first target peak and a behavior of the second target peak.
