Abstract:

In order to improve the overcharge safety of power battery as well as clarify the occurrence mechanism, the behavior characteristics and the propagation law of overcharge thermal runaway, the experiment on overcharge thermal runaway of NCM battery and battery pack are carried out. The results show that there is an obvious evolution process of overcharge thermal runaway. There is a time interval between the sharp shutdown of battery voltage and the exponential rise of battery temperature. The maximum temperature that each battery reached during thermal runaway process is elevated increasingly along with the thermal runaway propagation. Furthermore, the module structure to some extent can restrain the occurrence of overcharge thermal runaway. Finally, the suggestions for improving the overcharge safety of NCM battery and battery pack are proposed based on the above results.

Key words: vehicle engineering, NCM power battery, overcharge safety, thermal runaway propagation
