However, due to some safety hazards in electrochemical energy storage stations, electrochemical energy storage stations mainly use battery packs as energy storage media, and there is a risk of fire during the charging and discharging process of battery packs. When the liquid nitrogen fire extinguishing system is in use, when a fire is detected, the nitrogen tank will quickly pressurize the liquid nitrogen tank. When the pressure reaches the set value, liquid nitrogen will be sprayed from the spray head to the surroundings, rapidly cooling the surrounding environment and reducing oxygen (and other combustion-supporting gases) to quickly extinguish the fire.
