Claims

vertical.

8. Box (4) according to one of claims 6 or 7, characterized in that the box (4) comprises a hatch (25) capable of closing or substantially closing the cavity (20) for receiving the container (11) in the folded state and capable of opening the cavity (20) towards the ground to allow the deployment and / or inflation of the container (11) in the event of thermal runaway of the battery (2).

9. Box (4) according to the preceding claim, characterized in that the hatch (25) is fixed relative to the floor (6) by a hinge (24) and / or at least one zone of lesser resistance (26) and / or breakable or tearable fixing points (27), in particular under the effect of pressure generated by the deployment or inflation of the container (11) during thermal runaway of the battery (2).

10. Vehicle (1) hybrid or electric or comprising a fuel cell, in particular motor vehicle, characterized in that the vehicle (1) comprises a body (4) according to one of claims 6 to 9, or an arrangement (5) according to one of claims 4 or 5, or a storage device (10) according to one of claims 1 to 3.

11. Method of operating a box (4) according to one of claims 8 or 9, characterized in that, in the event of a malfunction of the battery (2), then the hatch (25) is moved simultaneously or substantially simultaneously with the inflation and / or unfolding of the conduit (12) and the container (11) due to the admission of gas (G) coming from the enclosure (3).
