Abstract

An apparatus for providing safety measures during gas release from a vehicle battery, such as a damaged lithium-ion rechargeable battery, arranged in a volume space having an opening includes at least one shroud element. The shroud element is configured to expand into the volume space by being filled with a gas such that, upon expansion of the shroud element, openings in the shroud element are enlarged and shroud element contents are discharged into the volume space through the enlarged openings in the shroud element. The apparatus further includes a device that, upon reception of a trigger signal, is configured to fill the shroud element at least partially with carbon dioxide gas such that carbon dioxide gas is discharged into the volume space as contents of the shroud element. An installation space includes the apparatus and a method is implemented to provide safety measures during gas release from the vehicle battery.
