Abstract:

Lithium-ion battery energy storage system has a fire safety problem that has become a key bottleneck restricting its large-scale promotion. The existing traditional gas fire extinguishing system based on fixed buildings has low fire extinguishing efficiency. Thus, this research work aimed at developing a prefabricated cabin-type lithium-ion battery energy storage system. Here, a targeted fire prevention and control equipment for an energy storage system was developed based on multi-layer collaborative early warning technology and different protection and fire-extinguishing strategies. First, a combustible gas sensor and Pack temperature sensor, which is an accurate, reliable, economical and practical multi-layer early warning technology, were built based on smoke/temperature detector. Second, lithium-ion battery fire-suppression system was added based on a heptafluoropropane fire-suppression system to meet the requirements of fire suppression of lithium batteries and the national standard electrical and fire protection design. The designed fire-fighting equipment supports multiple start of multi-point packs, which can effectively inhibit the re ignition of lithium battery fire. The combination of a fire-extinguishing system and a fire-suppression system ensure the safety of lithium battery energy storage system in all aspects.
