热失控的防护系统、防护方法及电池模组
By incorporating a pressure monitoring module and a flame-retardant module within the battery module, and combining these with a control module to identify the direction of thermal runaway propagation and spray flame-retardant media, the problem of insufficient thermal runaway propagation identification in existing technologies is solved, achieving effective flame retardancy against thermal runaway.

AI Technical Summary
In existing technologies, when a battery module experiences thermal runaway, temperature sensors or smoke sensors struggle to identify the spread of the runaway, resulting in a lack of targeted control in the fire protection system and making it difficult to effectively extinguish the flame.
A pressure monitoring module is installed inside the battery module. By monitoring the pressure signals at both ends of the cell stack, combined with the flame retardant module and control module, the direction of thermal runaway propagation is identified, and the flame retardant medium is controlled to be sprayed in the corresponding direction for flame retardancy.
It enables accurate identification and effective flame retardation of thermal runaway propagation, improves the targeting of fire protection systems, and reduces the risk of thermal runaway spread.
