锂离子电池EIS状态估计与安全预警研究进展
Research progress on EIS state estimation and safety warning for lithium ion batteries
摘要
Abstract
Electrochemical impedance spectroscopy(EIS),as an electrochemical testing technique,measures the impedance response of a battery by applying a small-amplitude AC excitation signal,which provides detailed information about the internal structure and chemical reactions of the bat-tery.In this paper,three applications of EIS-based testing for lithium ion battery state-of-charge(SOC)estimation,lithium ion battery state-of-health(SOH)estimation,and lithium ion battery safety warning are reviewed.The analysis and summary of the existing research work aims to provide refer-ence and reference for the development of state estimation and safety early warning technologies for lithium ion batteries.关键词
