Abstract
An apparatus for diagnosing a state of a battery includes a profile obtaining unit configured to obtain a voltage profile of a battery for voltage and capacity of the battery, and a control unit configured to obtain a differential profile for the voltage and the capacity from the voltage profile, select a plurality of peaks included in a predetermined voltage section of the obtained differential profile, determine a first peak associated with a negative electrode and a second peak associated with a positive electrode among the plurality of selected peaks, compare the first peak and the second peak with a first reference peak and a second reference peak of a preset reference profile, respectively, and diagnose a state of the battery based on at least one of a difference between the first peak and the first reference peak or a difference between the second peak and the second reference peak.
