Abstract: Abstract: With the rapid development of new energy vehicle power station industry, fire safety in the process of construction and use is very important. While energy storage technology and materials continue to develop and break through, effective fire prevention and fire extinguishing technical measures have not been followed up at the same time. Based on the analysis of the construction status, accident characteristics and fire risk of new energy vehicle battery swap station, this paper puts forward the fire prevention technology and management measures for the battery swap station based on the existing fire protection technical standards, and puts forward the fire extinguishing technical measures for the battery swap station based on the effectiveness experiment and demonstration of hexacarbon perfluorone gas-liquid biphasic lithium-ion battery fire extinguishing agent and special fire extinguishing system. It provides a theoretical basis for the fire safety construction and management of new energy vehicle battery swap station.
