Abstract
An apparatus for diagnosing a state of a battery includes a processor and memory having programmed thereon instructions that, when executed, are configured to cause the processor to obtain 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; determine a target peak located in a predetermined voltage section in each of the plurality of differential profiles; compare a plurality of voltages of a plurality of target peaks with a plurality of voltages of a reference peaks preset to correspond to each of the plurality of target peaks, and diagnose a state of the battery based on the voltage comparison result.
