Aging models for high capacity LiFePO4 cells

This paper deals with the capacity fade of a lithium iron phosphate (LiFePO4) battery for electric and hybrid vehicles. Thanks to low costs of small Li-Ion battery tests, many studies have analyzed life prediction models. The aim of this paper is to verify whether these models can be used to predict battery lifetime of a high capacity Li-Ion battery for full electric and hybrid vehicles, or not. During this study, a test bench has been developed to control a single cell charge and discharge current up to 300A. Finally, different literature aging models have been applied using the data obtained from experimental tests.
