The high specific energy,high safety and long life of power batteries are important guarantees for the development of new energy vehicle industry.The performance of automotive power batteries will be attenuated in use,and their durability is closely related to the environmental climate and service conditions.There is a complex many-to-many structure-activity relationship between the apparent performance attenuation and the microstructure evolution of power batteries,and it is necessary to carry out cross-dimensional collaborative analysis based on the whole life cycle evolution mechanism.This paper focuses on"health state assessment"and"aging mechanism analysis",and analyzes and prospects the key technologies for durability testing and evaluation of automotive power batteries based on the principle of battery aging,comprehensive performance,life and safety.
