Description
The data from accidents and intervention reports indicate that extinguishing fires in Li-ion batteries is challenging across various applications. A 2022 study in the stationary sector revealed that existing extinguishing systems, when equipped, often failed to effectively stop the spread of thermal runaway and generalized fires in containerized systems. In the automotive sector, extinguishing fires involving electric vehicle batteries is even more difficult due to the inaccessibility of the active battery components, which are integrated into different sub-assemblies and the vehicle chassis, hindering extinguishing agents from reaching the core of the battery pack.
This document aims to identify fixed and mobile extinguishing systems for Li-ion battery fires in electric vehicle applications and assess their effectiveness. It is based on literature research and discussions between Ineris and fire safety organizations.
