Thermal runaway sourceInternal short circuit / lithium / local temperature

For large storage plants, place early cell thermal-runaway sensing, multi-source cross-confirmation, BMS / PCS / EMS coordination, cabinet isolation, fire suppression, and station-level emergency response in one fire-safety system—and keep risk inside the smallest practicable boundary.
The system is working and the various parameters are in the safe zone.
System ActionsContinued monitoring without additional intervention.
Early unusual trends have occurred, but the warning threshold has not yet been reached.
System ActionsIncrease the frequency of sampling and enhance trend judgement.
Multiple-source signals meet warning or warning thresholds.
System ActionsStop charging and start fire-fighting.
Risks have increased, requiring physical isolation.
System ActionsCuts high pressure, isolates the malfunctioning cabinet and initiates fire suppression.
Start site-level emergency preparedness and personnel security process.
System ActionsPersonnel evacuation, open fire interfaces, emergency response.
