Abstract
A method for diagnosing a battery assembly according to one aspect of the present disclosure diagnoses a battery assembly including a battery bank comprising a plurality of battery cells connected in parallel with each other, and the method includes generating a differential profile representing a relationship between a differential capacity, which is obtained by differentiating a capacity of the battery bank with respect to a voltage of the battery bank, and the voltage of the battery bank; and diagnosing a state of the battery bank based on a difference value between a differential capacity value of a target peak located in a predetermined voltage section among a plurality of peaks of the differential profile and a differential capacity value of a valley adjacent to the target peak.
