摘要/Abstract

摘要： 动力电池包是一个复杂系统综合体，对复杂系统而言仅考虑组件的可靠安全性并不能保证其系统的安全性，迫切需要从系统层面分析评价动力电池包的安全性。运用复杂系统安全理论结合电动汽车实际工况，提出基于整体精细化模型可量化、层次化的动力电池包系统安全性评价。保证单体锂电池模型精细化的情况下，从正碰、侧碰、振动冲击三种常见工况对动力电池包进行仿真分析，采用层次分析（AHP）和模糊综合评价（FCE）相结合的方法对影响动力电池包系统安全的关键因素指标进行综合性安全评价。结果表明动力电池包系统安全性等级较低，安全性能较差。所提方法可为动力电池包正向结构设计和系统安全改善等工作提供参考。

Abstract: Power battery packs are complex system wholes. For complex systems, considering only the reliable safety of components does not guarantee the safety of their systems. It is urgently needed to analyze and evaluate the safety of power battery packs from the system level. Using the theory of complex system safety combined with the actual working conditions of electric vehicles, a quantifiable and hierarchical system safety evaluation of power battery pack is proposed based on the whole refinement model. To ensure that the model of the lithium-ion cells is refined, the power battery pack is simulated and analyzed from three common working conditions, such as positive collision, lateral collision and vibration impact, and the key factors affecting the system safety of power battery pack are comprehensively evaluated by the method of hierarchical analysis(AHP) and fuzzy comprehensive evaluation (FCE). The results show that the system safety of power battery pack has low level, and safety performance is poor. The method can provide reference for the forward structure design and system safety improvement of power battery pack.

Key words: complex system safety, evaluation method, integrated refinement model, power battery pack
