磷酸铁锂电池内短路检测方法研究综述
A Review of the Research on the Detection Dethod of Short Circuit in Lithium Iron Phosphate Battery
摘要
Abstract
Internal short circuit in lithium-ion batteries is one of the most common causes of thermal runaway accidents in lithium-ion batteries,and it is also frequently associated with improper use behaviors such as mechanical abuse,electrical abuse,and thermal abuse.It is a potential safety threat and has become an important hidden danger that restricts the safe operation of energy storage systems.This study first analyzes the formation mechanism of internal short circuit in energy storage batteries from four scenarios:internal structural defects,mechanical abuse,electrical abuse,and thermal abuse.Subsequently,this paper reviews the current research progress in the field of short circuit detection in energy storage batteries,both domestically and internationally.It summarizes the common detection methods,which primarily include model-driven method,data-driven method,multi-method fusion internal short circuit detection method and new technology internal short circuit detection method,and compares the application scenarios,advantages and limitations of these methods.Finally,the shortcomings of the current internal short circuit detection methods of lithium batteries are summarized and analyzed,and the future research of internal short circuit diagnosis methods is prospected.关键词
