Incremental capacity analysis (ICA) has proven to be an effective device for determining the state of health (SOH) of Li-ion tissues under laboratory conditions. This document deals with an outstanding problem of applying ICA in exercise: the evaluation of battery collection connections. The study uses fresh aging and characterization data of lithium iron phosphate (LFP) cellular material down to 53% SOH. The evaluability of battery series connections using ICA is confirmed by analytical and experimental considerations just for cells of the same SOH. For cells of different SOH, a method for identifying non-uniform aging states on the modules& amp; rsquo; IC curve is certainly presented. The findings enable the classification of battery modules with series and parallel connections based on partial terminal data.
