Lithium-ion battery module automatic fire extinguishing device successfully passed the inspection
Recently, the lithium-ion battery module automatic fire extinguishing device independently developed by the China Electric Power Research Institute has successfully passed the product inspection organized by the National Fire Equipment Quality Supervision and Inspection Center.
In order to effectively solve the problems of traditional fire extinguishing methods that do not have obvious inhibitory effect on lithium-ion battery fires and cannot prevent battery re-ignition, the China Electric Power Research Institute has launched special fire-fighting technology research , Independently developed a lithium-ion battery module automatic fire extinguishing device. The fire extinguishing device adopts a fire extinguishing method combining fire extinguishing agent and recombustion inhibitor. It adopts different fire extinguishing strategies according to different types of batteries. It has intelligent judgment and automatic start functions. It can quickly extinguish open flames without reburning. It also has low cost and Other facilities have the advantages of no damage and little impact on the environment. In the product inspection organized by the National Fire Fighting Equipment Quality Supervision and Inspection Center, a fire extinguishing test was conducted on the battery fire in the 10 kWh lithium-ion battery module. The automatic response time of the fire extinguishing device is only 0.5 seconds, and the battery fire can be extinguished within 3.5 seconds. , And the battery did not re-ignite within 24 hours, indicating that the device has excellent performance in extinguishing and suppressing re-ignition.
According to the introduction, the device is the first domestic fire extinguishing device that can effectively inhibit battery re-ignition for a long time, and solves the problem that lithium-ion battery fires are difficult to quickly extinguish and cannot prevent re-ignition for a long time. The technical problem of combustion has filled the gap in the field of safety and fire protection products for battery energy storage systems in my country, and is of great significance for ensuring the safe operation of energy storage systems.
