Study on combustion characteristics of ternary lithium battery-electric bicycle fires
The development and spreading process of electric bike fire is studied by carrying out physical combustion test on a ter-nary lithium battery-electric bicycle,and typical features such as combustion phenomenon,temperature and smoke change are ana-lyzed.The test results show that the e-bike fire develops rapidly,and the combustion process is accompanied by jet fire and explo-sion phenomena.The fire plume temperature measured at 1 m above the ground could reach up to 730℃,which corresponds to a maximum heat release rate of 1 290 kW.By evaluating the toxic-ity of the smoke,an effective dose percentage(FED)value of 1.8 is calculated,which indicates that about half of the people in this fire environment would be killed due to smoke toxicity hazards.In addition,the generated smoke contains a large amount of flam-mable and explosive gases,among which H2 content is highest at 2 300 μL/L.
