Zhao Z., Quan Q., Cai K., 2013, A Health Monitoring Method for Li-ion Batteries Based on Profust Reliability Theory, Chemical Engineering Transactions, 33, 961-966.
This paper presents an applicable health monitoring method for Li-ion batteries based on profust reliability theory. The word “profust” derives from “probability” and “fuzzy-state”, which means that the profust reliability theory is a kind of fuzzy reliability theory based on probability assumption and fuzzy-state assumption. It defines a concept of transition from fuzzy success to fuzzy failure to characterize system performance. In this paper, charge cycles of a battery are analysed, and the profust reliability is employed to estimate battery health state as a health indicator. Then, all operational states are classified into five health levels through profust reliability values. This process contributes a transform from quantitative reliability index to qualitative health level, which is able to describe system performance in a more intuitive way. Owing to the appealing ‘fuzzy’ advantage, the profust reliability theory can be effectively applied to the health monitoring of Li-ion batteries.
