It is found that the convection effect of the wind plays a leading role in the heat dissipation of the blocked LIB module when the wind velocity is less than 4.5 m/s. The heat conduction of the battery case plays a leading role when the wind velocity is greater than 4.5 m/s.
When a higher rate of airflow was used, the TR process of the battery was more intense, there was a greater amount of high temperature fused solid particles ejected from the battery, the TR heating rate was faster, and the peak temperature was higher. (These results will be further discussed in Sect. 3.2 .)
The cooling and asphyxiation effect of 0.5 MPa NWM is the best in natural ventilation environment, but the suppression effect of 0.5 MPa NWM on TR propagation of the LIB module is weakened under the influence of forced ventilation. However, different wind velocities have little effect on TR trigger temperature of the blocked LIB module.
A dynamic balance variable pressure cabin was set to a pressure of 30 kPa and used to simulate the low-pressure environment at the typical cruising altitude of the aircraft. The effects of airflow rates on the TR temperature, phenomenon, smoke, voltage and other characteristic parameters were studied for three different arrangements of LIBs.
When the airflow rate reached 60 m 3 /h or 70 m 3 /h, the oxygen content in the cabin was sufficient to maintain combustion of the battery, and the effect of convective cooling was greater than the effect of oxygen content on battery combustion. Therefore, as the airflow rate continued to increase, the TR time of the battery was delayed.
When the LIB module is blocked by the battery case, the forced convection of the wind cannot directly affect the LIB module, and the convection effect of the wind is weakened.
