摘要
阐述锂离子电池热失控是电化学储能电站安全的核心问题.探讨不同内部状态下锂离子电池热失控的建模,分析不同荷电状态(SOC)和不同健康状态(SOH)下的锂离子电池热失控行为,在不同SOC、SOH状态下的锂离子电池热失控机理建模和特征温度点,对比不同SOC、SOH下的特征温度点的变化并对热失控的危害性做出评估.
Abstract
This paper describes that thermal runaway issue in lithium-ion batteries is a crucial safety concern in current electrochemical energy storage systems.This paper primarily focuses on the modeling of thermal runaway in lithium-ion batteries under different internal states,analyzing the thermal runaway behavior under various state of charge(SOC)and state of health(SOH)conditions.The research aims to establish models and analyze characteristic temperature points of thermal runaway in lithium-ion batteries under different SOC and SOH states.Furthermore,the variations in characteristic temperature points under different SOC and SOH conditions is compared,and the potential hazards associated with thermal runaway isevaluated.
