It is reported that as more and more energy developers will battery energy storage system into the plans for solar power generation facilities, many insurance companies are assessing the battery energy storage system may lead to fire risk. To this end, an American insurance company to develop and release a battery energy storage system for fire control guidelines.
as lithium ion battery costs falling, in the past decade, the United States energy storage system capacity has been increased from 1 mw to 700 mw. But according to the Global commercial property insurers and risk management consultancy FM Global's recently published a survey report, industry players rarely study of effective fire prevention strategy of energy storage system to guide the business operations of the user.
FM Global company senior chief research engineer Benjamin Ditch in the company in stages the actual test report issued a statement saying: & other; Energy storage system brings security challenges on the one hand, on the other hand, has brought about great hope for the development of clean energy. ” The test is in FM Global company research carried out in the park, the park is the world's largest fire technology lab.
FM Global company's investigation report, & other; Lithium ion batteries and other batteries ( Such as lead-acid) The main difference between the possibility of thermal runaway reaction, the reaction can lead to combustible gas leakage, and then can burn. ”
in the nonprofit organization property insurance research group ( PIRG) Working with fire research foundation, the United States in the first phase of the relief in the study of fire risk, fire risk assessment of battery energy storage system, and developed the installation of a lithium ion battery energy storage system, strategy for guiding fire and emergency safety practice.
the latest phase of the test are mainly concentrated in the lithium iron phosphate ( LFP) Battery or nickel cobalt manganese oxide ( NMC) Battery of battery energy storage system, and assuming the battery in & other; Abuse & throughout; Under the condition of running, which reduce the fire danger of proprietary battery management system has not been activated.
the test range from a single cell module to complete battery energy storage system, each contains 16 battery energy storage system module. In general, the lithium iron phosphate ( LFP) The risk of battery is low, water spray is regarded as the two battery test is the most effective fire extinguishing agent.
FM Global company to lithium iron phosphate ( LFP) Battery or nickel cobalt manganese oxide ( NMC) Battery in testing the freedom and spray combustion heat release rate is
if the battery energy storage system may cause fire, need to configure the security personnel to guard until all possible damage to the battery energy storage system ( Lithium ion battery) Removed from the area.
the final recommendation is that due to involving the lithium-ion batteries in the initial fire within a few minutes to a few days after the events will re-ignite at any time, in order to prevent light again, need to sufficient battery cooling.
although the study was designed to fire regulations and has jurisdiction over the relevant departments to provide useful information, but FM in a Global company, called 'the development of the automatic sprinkler system' in the report provided with automatic spray extinguishing system positioning, the density of water discharge and battery system associated with the spatial separation of flammable and combustible objects specific guidelines for information. FM Global companies on its web portal extinguishing guidelines released the lithium ion battery energy storage system.
Ditch, said & other; Our research shows that in the field of business and industry applications of battery energy storage system, automatic water spray device can be used, and maintain proper spacing, can make its safe operation. ”
