In this paper the capacity fade of a Li-Ion battery for electric and hybrid vehicles is studied. The battery lifetime is a crucial characteristic for the usage of this technology on Full Electrical Vehicle (EV) or Hybrid Electrical Vehicle (HEV). Thanks to low costs and easy electronic devices design for small Li-Ion battery tests, many studies have established life prediction models.
The aim of this paper is to verify whether these models can be used to predict capacity fade for 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 charge and discharge cell current. At last a comparison between different models will be provided.
