This paper deals with the capacity fade of a lithium iron phosphate (LiFePO 4 ) 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.

Abstract

This paper deals with the capacity fade of a lithium iron phosphate (LiFePO 4 ) 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.
