- Abstract:
- With the annual increase in the number of new energy vehicles in China, fire incidents involving power battery vehicles continues to rise. The existing automatic sprinkler system demonstrates inadequate firefighting effectiveness. In view of this, high-pressure water mist was selected as the fire extinguishing medium for power battery vehicles. This paper summarized the characteristics and fire extinguishing capability of high-pressure water mist, and provided an in-depth discussion on the design for implementing high-pressure water mist systems in both indoor and outdoor electric vehicle charging parking garages. Given the constraints imposed by the current code, the open system was integrated with the localized application system, and the length of the dry pipe network was restricted to within 300 m. Consequently, only a single set of pumps was installed throughout the entire underground garage. In the localized application system, the efficacy of fire extinguishing was ensured by augmenting the spray intensity to 3.04 L/(min·m2). To enhance the system’s emergency response speed, the new infrared temperature sensors and the vehicle battery pack’s temperature control system were employed to activate the high-pressure water mist fire extinguishing system. The system has a good fire extinguishing effect, and can provide reference for similar projects.
