摘要：
Aiming at the thermal runaway problem of power battery during the use of electric vehicles，a power battery emergency thermal management system is proposed in this paper，which sprays high-pressure liquid refrigerant onto the surface of overheated battery to cool the battery in seconds. Experiments were conducted to analyze the effects of spray time，spray duty cycle and spray frequency on the cooling capacity of the system. The results show that when the spray time is 5 s，the average temperature drop of unit mass refrigerant is much lower than that of spray time is 6 s，which can be －41.94 ℃/kg，and the utilization efficiency of refrigerant is improved；when the duty cycle of pulse injection is 90%，the cooling capacity of the system can be enhanced by 10% than that of continuous spray，and the utilization efficiency of refrigerant also improves slightly；when the frequency of pulse injection is 2 Hz，the cooling capacity of the system exceeds that of continuous spray，and the cooling capacity of the system can be enhanced by 19.4%. © 2022 Editorial Board of Jilin University.
