AI Technical Summary
When the lithium secondary battery experiences abnormal temperature rise and internal gas generation, the leakage of exhaust gas and high-temperature sparks can cause fires to spread. Furthermore, oxygen can easily be introduced into the module, leading to short circuits. Existing technologies are unable to effectively prevent this.
It adopts a modular housing structure with a spark direction changing section, spark delay protrusions and recesses, combined with a busbar frame and fireproof sheet assembly to prevent high-temperature spark leakage and prevent external oxygen from entering, thus preventing fire spread and short circuits.
It enables rapid discharge of exhaust gases, prevents high-temperature spark leakage and external oxygen entry, effectively prevents the spread of fire and short circuits between adjacent battery cells, and improves the safety of the battery module.
