[0002] At present, lithium-ion battery production is one of the leading energy storage technologies, but lithium-ion battery fires are sudden and develop rapidly. Early detection and warning are key links. Therefore, identifying early fire alarms, receiving cluster-level fire alarm signals with space-level fire-fighting equipment, and then linking fire suppression equipment to effectively control its harmfulness are one of the core tasks of energy storage power station safety.

[0003] At present, a large number of single cells form battery packs inside energy storage power stations. Multiple battery packs are stacked to form battery clusters. Multiple battery clusters are arranged in containers to form energy storage power stations. In addition, electrical equipment is also placed in the energy storage power station container.
