Abstract

The frequent occurrence of power battery safety issues has seriously hindered the healthy development of the new energy vehicle (NEV) industry. With the widespread use of power batteries, problems such as thermal runaway, overcharging, and aging failures have become increasingly prominent. Power battery safety early warning technology plays a crucial role in ensuring the safe operation of batteries by monitoring key operating parameters, identifying abnormal states, and issuing early warnings. This paper reviews the research progress and current application status of power battery safety early warning technologies, systematically analyzes the internal and external factors affecting battery safety, summarizes mainstream technical approaches including threshold detection, state of health (SOH) analysis, model-based prediction, and data-driven methods, discusses the existing challenges such as data quality, feature extraction, model generalization ability, and limited early warning accuracy, and looks forward to future development directions. It emphasizes improving battery safety management and lifetime prediction capabilities through advanced sensors, intelligent algorithms, and the “Terminal-edge-cloud” collaborative architecture.
