Apparatus And Method For Diagnosing Battery

Abstract: An apparatus for diagnosing a battery according to an embodiment of the present invention comprises: a profile acquisition unit configured to acquire a differential profile indicating a corresponding relationship between a voltage of a battery and a differential capacity with respect to the voltage; and a control unit configured to determine a target peak from the differential profile, determine a first comparison result obtained by comparing the voltage between a reference peak of a reference profile preconfigured for the battery and the determined target peak and a second comparison result obtained by comparing the differential capacity between the reference peak and the determined target peak, and determine a state of the battery on the basis of the first comparison result and the second comparison result.
