Zusammenfassung:	System and methods for identifying a weak subdivision in a battery system are presented. In certain embodiments, a system may include a battery pack that includes multiple subdivisions. A measurement system may be configured to determine multiple subdivision electrical parameters associated with the subdivisions. A battery control system may identify a weakest subdivision based one on or more calculated derivative ratios of a subdivision electrical parameter associated with one subdivision of the battery pack relative to a subdivision electrical parameter associated with another subdivision.
