Abstract
An apparatus for diagnosing a battery cell according to an embodiment may include a voltage measurer that measures a voltage of each battery cell of a battery module in a state of an open circuit voltage of a battery, a memory that stores the measured voltage at predetermined time intervals, and an abnormality detector that compares a current measured voltage with a measured voltage before a preset time for each battery cell and determines that an abnormality has occurred in a first battery cell among the battery cells when a difference between the current measured voltage of the at least one battery cell and the measured voltage of the at least one battery cell before the preset time exceeds a reference value.
