In this paper, a fire occurred during the charging process of a device using a series of lithium secondary batteries, such as a solar cell car, at OOOOOOOO University (Nam Inchon Campus) located in Juan-dong, Nam-gu, Incheon, on May 07, The cause of the fire was analyzed and inferred through a real fire experiment. Although the fire and explosion accidents of lithium secondary batteries occur every year and safety standards for them are gradually upgraded, objective and rational accident analyzing methods of lithium secondary batteries and sharing of accident cases are systematically carried out after ignition and explosion And when a lithium secondary battery is ignited or exploded, the appearance and deformation of the external appearance are so severe that it is difficult to analyze the cause of the clear reason. In this study, the rechargeable lithium secondary battery sold in the market was selected, and the situation where the battery was charged during the charging situation was pointed out and the possibility of the ignition was reproduced and analyzed by changing the condition of the charging condition. I would like to use it as a reference for analysis.
