电动车辆动力电池安全预警策略研究综述

Battery safety has become an important issue restricting the development of electric vehicles. Accurate and timely battery safety warning can ensure the safety of occupants' life and property and improve the safety level of electric vehicles. A comprehensive review on the battery safety warning strategies in electric vehicles is conducted in this paper. Firstly，the definition of battery safety state is reviewed，and the framework of this review is proposed. Then，the battery safety characteristics and safety influencing factors analysis，battery-modeling methods，battery safety risk assessment/prediction methods are reviewed in detail. The advantages and disadvantages of different methods are summarized. Finally，the achievements and deficiencies of existing researches are summarized，and the development trend of battery safety warning technology in electric vehicle is proposed，including the new sensor technology，multi-factor integrated battery safety warning method and "terminal-side-cloud " battery safety warning system. This review provides a reference for further research on the safety warning strategy of electric vehicle battery.
