Fire Risk Analysis of Electric Bicycle Centralized Charging and Research on Intelligent Fire Protection System

This study presents an in-depth analysis of fire hazards associated with centralized electric bicycle charging shelters, placing specific emphasis on fires originating from lithium-ion battery (LIB) thermal runaway. To resolve the critical issue that conventional firefighting infrastructure fails to effectively suppress lithium battery fires, this research develops a holistic smart fire safety system that seamlessly integrates "intelligent real-time monitoring, early-stage pre-alarm, targeted fire extinguishing, and cloud platform management". This system enables automatic fire identification and partitioned high-precision water mist fire suppression. The experimental results verify that the proposed system can remarkably elevate the fire safety performance of charging shelters, offering both theoretical underpinnings and practical technical references for the fire safety design and standardized operation of urban centralized electric bicycle charging sites.
