摘要
本文中对不同类型隔热层对电池模组热失控蔓延特性的影响进行了实验研究。结果表明:隔热层具有延长电池模组热蔓延时间、防止电池喷阀后起火和降低模组热蔓延最高温度的作用;其中预氧化丝气凝胶隔热层热蔓延抑制效果最优,其模组完全热蔓延时长是使用陶瓷气凝胶隔热层模组的138%,是使用纳米玻璃纤维隔热层模组的279%。
In this paper,an experimental study on the effects of different types of heat insulation layer on the propagation characteristics of thermal runaway in battery modules is conducted.The results show that heat insulation layer can extend the heat spread time of battery module,prevent the fire caused by valve eruption in battery and lower the peak temperature in the thermal runaway of battery module.Among them,the thermal runaway propagation effect of the insulation layer of preoxidized fibers aerogel has the best effect in suppressing the propagation of thermal runaway.Its total propagation time of thermal runaway is 138%longer than that of ceramic aerogel,and 279%longer than that of nano-glass fiber.
