Secondary Li-ion batteries are considered the most sustainable power supplies for electric vehicles (EVs). With the extensive implementation of EVs, we are starting to find an expanding number of safety accidents triggered by Li-ion batteries in EVs globally. Battery EV fire produces intense heat, smoke, and complex toxic gasses. Among them, toxic gasses are a major threat to human health. Therefore, it is necessary to study the detailed identification of gas emissions from the battery fire. Previous studies reported the emission of toxic gases after firing the different types of batteries, still unknown gasses are not studied or quantified. Particularly, real-time gas analysis is not explored very well which motivates us to conduct this work. In this study, we will conduct a large-scale battery fire test at the predesigned fire station, subsequently, the collected gas will be analyzed using appropriate gas monitoring analytical tools like FT-IR and gas chromatography (GC). In the end, we will compare the offline and online gas analyses followed by quantifying the toxic gases. This investigation will provide a detailed understanding of battery electric vehicle fire and associated health risks.
