Recently, GB/T 42288-2022 "Safety Regulations for Electrochemical Energy Storage Stations" under the jurisdiction of the National Electric Energy Storage Standardization Technical Committee was released. This national standard puts forward clear safety requirements for the equipment and facilities, operation and maintenance, maintenance tests, and emergency disposal of electrochemical energy storage stations, and is applicable to stations using lithium-ion batteries, lead-acid (carbon) batteries, redox flow batteries, and hydrogen storage/fuel cells, other types of electrochemical energy storage stations can use it as a reference. The standard points out that the battery room/chamber should be equipped with an automatic fire extinguishing system, which is linked with the battery management system(BMS), fire detector or flammable gas detection device, air conditioner, and exhaust system, and has the functions of remote passive command start and emergency mechanical start. The minimum protection unit of the automatic fire extinguishing system should be a battery module, and each battery module should be equipped with a detector and a fire extinguishing medium nozzle separately. The fire extinguishing medium should specifically have good insulation and cooling properties, which can extinguish battery fires and electrical equipment fires and prevent re-ignition.
