摘要
通过电阻丝加热和针刺方法使动力电池内短路,研究动力电池的热失控方法。试验结果表明:不同试验方法触发电池内短路引发的热失控对相邻电池的影响不同,针刺方法比电阻丝加热更适合于动力电池热失控验证,电阻丝加热产生的热量增大了动力电池发生热失控的机率。
Two methods of the internal short circuit of the dynamic lithium-ion battery were carried out to research the thermal runaway of the dynamic lithium-ion battery.The results show that the thermal runaway of the dynamic lithium-ion battery performs differently at the different test methods. The nail penetration is more suitable for the dynamic lithium-ion battery than the heating by the resistive wire and the heating of the battery will generate more heat,witch make the thermal runaway of the dynamic lithium-ion battery easier.
