电池系统的故障树

Higher Priority Cell Level Events 

• Internal short circuit resulting from a cell separator failure caused by a Cell Crush 

Higher Priority Pack Level Events 

• Chemical event involving a pack breach interior to the passenger department caused by a mechanically induced failure. This would be a pack containment failure due to crash

• Chemical event involving a pack breach interior to the passenger department caused by a thermally induced failure. This would be a Pack containment failure due to high temperatures, not fire

• Mechanical event caused by a pack structure failure, a failure of the structure due to crash

• External short circuit caused by battery internal conductors being forced together in a crush event by mechanical forces on a pack

• External short circuit caused by conductive fluid allowing a short circuit across cells

Higher Priority Vehicle Level Events

• Ignition of the vehicle from a source outside of the pack capable of igniting a combustible mixture 

这份报告里面有大量的实验环节，都是基于挤压、过充和短路实验三种不同的形式来验证以上的故障发生时，整体的情况，我需要点时间把报告里面的内容归类和整理
