Apparatus and method for diagnosing battery

Abstract

An apparatus for diagnosing a battery includes a profile obtaining unit configured to obtain a first differential profile based on a differential voltage of the battery and capacity of the battery corresponding to a charging process and a second differential profile based on the differential voltage of the battery and capacity of the battery corresponding to a discharging process; and a control unit configured to calculate a number of charging peaks included in a first capacity section from the first differential profile, calculate a number of discharging peaks included in a second capacity section from the second differential profile, and diagnose a state of the battery based on the number of charging peaks and the number of discharging peaks.
