Compared with the traditional fixed energy storage power station, the energy storage container allows ocean and road transportation, has strong mobility, is not limited by regions, and is convenient and quick to use.
However, the energy storage container has large battery consumption and high integration level, and the thermal runaway of individual batteries can easily cause the heat to be spread to the whole container, even to cause fire. Once a fire occurs, the fire spreads rapidly, and after the open fire is extinguished, the risk of secondary reignition exists. The solution of the energy storage container fire-fighting system is based on the principle of early discovery and early disposal, and advocates early warning and timely disposal of the primary stage of thermal runaway of the lithium battery in the container to prevent fire.
In the prior art, most of the air-conditioning air-cooling modes are adopted for cooling the batteries and the whole container, but the air-cooling heat dissipation efficiency is low, the heat dissipation is uneven, and the phenomena of difficult fire extinguishment or incomplete fire extinguishment can occur when thermal runaway or fire occurs. In the chinese patent CN 214254526 "a new type lithium battery energy storage container system", the water cooling system is used to cool the battery, the fire fighting system and the water cooling system are combined into a system, the water cooling liquid is changed into fire fighting liquid, and the external fire fighting bottle, the external pipeline and the fixing device are cancelled, although the arrangement of the pipeline is seemingly simplified, the space and the cost are saved, because the water cooling and the fire fighting share the pipeline, the use is inconvenient.

However, the technology is limited to cooling the battery, and no corresponding measures are taken for fire caused by thermal runaway.
In chinese patent CN 215869542 "a thermal management and fire fighting device for battery of energy storage container", a device for quickly cooling battery in time by a cooling device is disclosed; when the temperature of the battery exceeds a set threshold value, fire early warning can occur, and meanwhile, a fire-fighting system is started to extinguish fire in time. However, in the patent, an air cooling mode is adopted, and fire extinguishing devices are a gas fire extinguishing device and a water fire extinguishing device; the gas fire extinguishing medium is heptafluoropropane, which does not damage the battery, but is harmful to human body when the concentration exceeds 10%. The water fire fighting device does not store water inside, and a fire disaster needs to be manually connected to an external fire hydrant by a pipeline, so that the automation degree is low, and the operation is difficult.
In chinese patent CN 214165973 "energy storage container", a technology for improving the heat dissipation efficiency of an energy storage container is disclosed, in which a plurality of operation windows are arranged along the length direction of a box body, and the operation windows correspond to the positions of battery racks; the technology adopts an air cooling mode to cool the battery, and simultaneously adopts a spray head arranged at the top of the box to extinguish fire.
