Capacity fade detection in lithium-ion batteries using non-linear frequency response analysis (NFRA) under multiple open-circuit voltages (OCVs)



Origin of the dataset is from Ivium-n-stat (for harmonics) and Neware Cycler (BTS4000) for cell ageing. The output of the ivium is in the form of SQLITE file (opened bu DB browser), where the harmonics can be extracted using IVILAB. The harmonics are in absolute voltages which are converted into percentages with respect to fundamental. Being too noisy, the data then smoothed down using Matlab.
