The invention discloses an immersed liquid-cooled battery energy storage system and a working method thereof.The immersed liquid-cooled battery energy storage system comprises a battery cabinet and a circulation system module, and the battery cabinet comprises at least one battery module; the battery module comprises a battery box filled with temperature-adjusting insulating liquid and a battery pack which is positioned in the battery box and is immersed in the temperature-adjusting insulating liquid; the circulating system module is connected with the battery box and comprises a fire extinguishing system suitable for spraying fire extinguishing cooling liquid to the battery cabinet when the battery cabinet is in a fire disaster; wherein the temperature-adjusting insulating liquid and the fire-fighting cooling liquid are the same medium, and are jointly driven by the circulating system module to circulate. Cooling and fire fighting of the battery are integrated, the safety, stability and adaptability of the battery energy storage system can be greatly improved, and the problems that in the existing cooling technology, the capacity density is low, and in the fire fighting technology, the system is complex, and the cost is high are solved.
Description
technical field [0001] The invention relates to a submerged liquid-cooled battery energy storage system and a working method thereof, belonging to the technical field of energy storage batteries. Background technique [0002] At present, with the continuous improvement of my country's energy consumption structure, the energy storage battery industry has shown explosive development. The standard series of energy storage battery compartments is the main application form of the energy storage battery industry in the future, and the security and stability of the energy storage system are getting better and better. The more people pay attention. Energy storage batteries will generate a lot of heat during charging and discharging applications, and there is a risk of battery combustion or explosion. Therefore, research on battery cooling and fire protection is particularly important. At present, the mainstream energy storage battery cooling methods in the market are mostly air-cool...
