1. A system for extinguishing a fire and/or preventing a fire from starting or restarting in an electric vehicle including a module or a battery pack comprising a plurality of electrochemical batteries, comprising:
a self-supporting inflatable structure, the shape and dimensions of which when deployed are configured to lift the electric vehicle off a 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; and
a liquid supply device configured to fill, at least partially, a sealed volume delimited inside the peripheral barrier and by the liner with a liquid, so as to immerse at least the module or battery pack in the liquid,
wherein the self-supporting inflatable structure comprises at least one lifting cushion which deploys vertically under the vehicle as it inflates and a flexible strip extending from a bottom of the at least one cushion and deploying when it is inflated under the lifted electric vehicle toward a periphery thereof, so as to create the liner,
the lifting cushion being configured to lift the vehicle when deployed so as to allow the flexible strip to deploy under the lifted electric vehicle.
