Abstract

A system for extinguishing a fire and/or preventing a fire from starting or restarting in an electric vehicle having a module or a battery pack with a plurality of electrochemical batteries, in particular metal-ion batteries, includes a self-supporting inflatable structure, the shape and dimensions of which when deployed are configured to lift the electric vehicle off the ground, create a liner between the ground and the electric vehicle, and create a peripheral barrier in continuity with the liner, which is closed upon itself, around the electric vehicle. The system also includes a liquid supply device for filling, at least partially, the sealed volume delimited inside the peripheral barrier and by the liner, so as to immerse at least the module or battery pack in the liquid.
