摘要： 电池热失控风险已经成为制约新能源行业发展的瓶颈问题。针对电池热失控应急处置难题，开发了电池模组热失控浸没抑制试验平台，开展了不同注入策略下电池热失控试验，研究了浸没液对延缓电池热失控和防止电池热失控的有效性。结果表明，当电池热失控后，在浸没液40 s注满模组箱的前提下，可抑制电池温升，最大降温速率可达78.7 ℃/s；当电池开阀后，在浸没液40 s注满模组箱的前提下，最大降温速率可达17.9 ℃/s，可防止热失控发生。

Abstract: The risk of battery thermal runaway has become a bottleneck problem restricting the development of the new energy industry. In response to the emergency response problem of battery thermal runaway, this paper developed a battery module thermal runaway immersion suppression experimental platform, conducted battery thermal runaway experiments under different injection strategies, and studied the effectiveness of immersion liquid in delaying battery thermal runaway and preventing battery thermal runaway. The results showed that when the battery thermal runaway occurred, the disposal condition of filling the module box with immersion solution within 40 seconds could suppress the temperature rise of the battery, with a maximum cooling rate of 78.7 ℃/s; When the battery valve is opened and the immersion liquid is filled into the module box within 40 seconds, the maximum cooling rate can reach 17.9 ℃/s to prevent thermal runaway.
