Evaluation Model for Lithium-Ion Battery Deterioration (First Report)
Published October 03, 2012 by Society of Automotive Engineers of Japan in Japan
Lithium-ion Batteries (LiB) are increasingly being used in automobiles and buildings since the late 2000s. Although the lifetime of several years is long enough for LiB used for electronic devices, a lifetime of more than 10 years is required for LiB in infrastructure. However, users of LiB are submitting to the uncertainty of the lifetime of LiB. This problem is one of the causes which prevent the spread of use of LiB. Therefore, it is important to predict the degradation of battery performance, evaluate the lifetime of LiB based on present performance and how to use them in the future. Our team developed an evaluation model for used LiB, which contains two elements: Degradation speed database based on experiment and the method of setting up the use pattern of LiB.
