In this paper, an extension to high C-rates of State of Health (SoH) diagnostic methods based on Incremental Capacity (IC) peak tracking is proposed. A set of eleven NCA Lithium-ion batteries who went under different ageing protocol is used. Charge and discharge cycles are performed at C/20, C/10, C/5 and C/2, and then used for IC analysis. Correlations between the variations of IC peaks and SoH are presented and modelized, and shown to be accurate estimators for all tested C-rates.Read less <
