A battery system includes at least one battery apparatus having at least one apparatus for increasing safety when using a degassing apparatus. The degassing apparatus is suitable for the controlled degassing of battery apparatuses. The battery apparatus and the apparatus are surrounded by a housing. The degassing apparatus is inserted into a wall of a housing. The apparatus generates a physical distance between the battery apparatus and the degassing apparatus such that a space is kept free between the battery apparatus and the degassing apparatus for discharging substances, which emerge from the battery apparatus, to an area surrounding the battery system.
