Kind Code:
B2
Abstract:
An apparatus for diagnosing a battery cell according to an embodiment of the present invention may include a voltage measurement unit 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 detection unit 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 the battery cell when a difference between the current measured voltage and the measured voltage before the preset time exceeds a reference value.
