基于航空锂离子蓄电池组热失控特性的排气设计及应用分析OA

In this paper,the exhaust mechanism and gas production composition of thermal runaway of aviation lithium-ion battery group are briefly analyzed,and the inducement and influence of thermal runaway of aviation lithium-ion battery group are analyzed from both external and internal factors.By considering the actual installation environment,the ignition and explosion gas concentration and failure probability of thermal runaway exhaust of aviation lithium-ion battery pack are studied.From the angle of system design,it provides data reference and technical support for the thermal safety design and control strategy of lithium-ion battery pack.
