Experimental Study on Thermal Runaway Hazard of Electric Vehicle in Oil-gas Power Station
摘要
Abstract
In view of the risks and hazards of thermal runaway of electric vehicles,a simulation test plat-form for thermal runaway of electric vehicles with lith-ium-ion batteries was built,and experimental studies on the temperature rise,gas production and fire char-acteristics of lithium-ion batteries after thermal runa-way were carried out.The test showed that before the safety valve was opened,the lithium-ion battery would escape a small amount of H2 and CO,and the concentration of H2 was larger than the concentration of CO.When the thermal runaway safety valve of the battery was opened,H2,CO and VOCs gas were quickly discharged.By comparing the response time of the detector,the response of H2 and VOCs was fas-ter,and the maximum peak concentration of H2 can reach 57 × 10-6,exceeding the maximum concentra-tion of CO.The total time from thermal runaway gas production to complete combustion of the 60 Ah lithi-um-ion battery was 1 221 s.The lithium-ion battery burned violently and had a high temperature.The maximum flame temperature of a single battery reached 550 ℃,which led to the risk of explosion.关键词
