Abstract
To mitigate the risk of fires in containerized lithium-ion battery energy storage systems,we propose an early warning method for fire safety.This method involves analyzing the heat generation process in such systems and establishing the correlation between temperature,voltage,and the fire safety of the storage system.By collecting operational data,including voltage,current,temperature,and acoustic signals,we assess the system's surface health and predict its operational trends based on changes in the operational data and surface health status.Considering various influencing factors,we establish early warning levels for the system's fire safety and implement a comprehensive early warning system.Performance testing demonstrates that,compared to conventional warning methods,our optimized approach significantly reduces the rates of false positives and negatives by more than 0.90%.Furthermore,the method exhibited only one warning error across different warning levels,and achieved a warning accuracy of 99.7%across various surface damage locations,proving its effectiveness and reliability.关键词
