Quantifying the Fire Hazard from Li-Ion Battery Fires Caused by Thermal Runaway in E-scooters
Over the last 20 or so years, lithium-ion battery (LiB) powered devices have infiltrated our day to day lives through the devices that rely on them for energy storage including phones, cordless tools, toys, wristwatches, and vehicles. With the meteoric rise in popularity of LiBs in society, failures due to misuse, mishandling, or a poor understanding of necessary safety features may be expected. This study quantifies the fire hazard of a seated E-scooter with a LiB in thermal runaway during overcharging. Heat release rate (HRR) was measured for LiB battery in isolation and subsequently installed in an E-scooter to determine the battery’s contribution compared to the complete device. Two scenarios were evaluated to assess the hazard an E-scooter may pose in a residential scale building: an overcharging E-scooter in a closed bedroom and an overcharging E-scooter in a common living-kitchen area. The results of this study clearly demonstrates the extreme hazard posed by an overcharging E-scooter to the occupants.
期刊介绍：
Fire Technology publishes original contributions, both theoretical and empirical, that contribute to the solution of problems in fire safety science and engineering. It is the leading journal in the field, publishing applied research dealing with the full range of actual and potential fire hazards facing humans and the environment. It covers the entire domain of fire safety science and engineering problems relevant in industrial, operational, cultural, and environmental applications, including modeling, testing, detection, suppression, human behavior, wildfires, structures, and risk analysis.
The aim of Fire Technology is to push forward the frontiers of knowledge and technology by encouraging interdisciplinary communication of significant technical developments in fire protection and subjects of scientific interest to the fire protection community at large.
It is published in conjunction with the National Fire Protection Association (NFPA) and the Society of Fire Protection Engineers (SFPE). The mission of NFPA is to help save lives and reduce loss with information, knowledge, and passion. The mission of SFPE is advancing the science and practice of fire protection engineering internationally.
