Abstract

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