锂离子电池热失控早期特征及预警方法综述OA北大核心CSTPCD

The importance of using of lithium battery in the process of industrialization is self-evident.The thermal runaway fault warning technology is crucial for the safety of energy storage systems.The introduction of lithium ion battery thermal runaway in the context of energy storage systems was taken as the starting point,early warning methods based on temperature,gas,internal resis-tance,voltage characteristics and machine learning using multi-dimensional signals were introduced,and the application of the above lithium ion battery thermal runaway warning methods in the energy storage system was summarized.Finally,the development prospects of thermal runaway warning methods for lithium ion batteries used in energy storage systems were prospected and some sugges-tions were put forward.
