A battery fire refers to a thermal event in which a battery—most commonly a lithium-ion battery—catches fire due to internal or external conditions that lead to overheating, chemical instability, or thermal runaway. Battery fires are rare under normal use but can be highly energetic, fast-spreading, and difficult to extinguish, making battery safety a critical design and operational priority.
Prevention and Mitigation:
Battery Management System (BMS): Prevents unsafe voltage, current, and temperature conditions
Thermal management systems: Keep cells within safe temperature ranges
Robust mechanical design: Prevents impact damage and isolates faults
Certification & testing: Compliance with standards like UN 38.3, UL 9540A, IEC 62660
