[0031] Working principle: Use lithium battery safety monitoring system as an early combustible gas detector to detect combustible gases such as hydrogen earlier. Based on the characteristics of electrical equipment sending fire information, the temperature sensing detector is cancelled and two smoke detectors are used to replace the smoke plus temperature detection solution, which is more reliable and timely.

[0032] The fire protection system is divided into 4 stages:

[0033] In stage 1, the early combustible gas detector detects that the combustible gas such as hydrogen exceeds the standard, sends an alarm signal to the fire control panel, and starts the explosion-proof exhaust fan to remove the combustible gas in the cabinet;

[0034] In stage 2, the battery thermal runaway continues. For example, if a smoke detector detects smoke, the detector sends an alarm signal to the fire control panel, and the fire control panel sends a fire alarm signal to the EMS, which shuts down the battery system charging and discharging and the PCS.

[0035] Stage 3: If two or more smoke detectors detect smoke, the fire control panel sends a fire alarm signal to the EMS and triggers the release of fire extinguishing agents, while shutting down the explosion-proof exhaust fan;

[0036] In stage 4, if the firefighters determine on-site that the batteries in the cabinet are still at risk of reignition, they can connect fire water through the fire water pipe interface outside the cabinet to form a fire water spray inside the cabinet to cool down the system and extinguish the fire, eliminating the risk of reignition and ensuring the safety of personnel.
