Avgassing fra litium-ion batterier i hjemmet

Abstract: 
This study evaluates venting from lithium-ion batteries in homes and is commissioned by the Norwegian Directorate for Civil Protection (DSB) and the Norwegian Building Authority (DiBK). The main objective is to study the extent to which venting from a battery in a dwelling can pose a risk for people, focusing on the consequences associated with venting. The Norwegian fire statistics database BRIS was used to identify relevant scenarios. Based on these scenarios, a total of nine numerical simulations of gas dispersion in a generic dwelling were carried out. Boundary conditions, such as gas quantity and composition, were based on a literature study. The simulations were used to evaluate the potential for accumulation of an explosive gas mixture, exposure to toxicity-related gases (both asphyxiants and irritants) and the possibility of detection of carbon monoxide (CO).
