In this paper, we introduce that the actual ignition point and the main combustion point may be different in case of a battery fire. In addition, the possibility of misuse of chargers could be suspected through precision investigation of different battery explosion cases. To verify this, an overvoltage applied experiment was conducted on a similar battery, and as a result of the experiment, it was confirmed that the P-IC module mounted in the PCM was preemptively damaged, and then the overcharged battery cell electrode led to an explosion.
