The present invention relates to a device for providing safety measures during gas release from a vehicle battery (2), in particular from a damaged lithium-ion accumulator for hybrid or electric vehicles, wherein the vehicle battery (2) has an opening (4) having volume space ( 1) is arranged, with at least a first and a second gas-fillable, openings (8, 8 ') having enveloping element (7, 7', 17, 17 '), which are each formed by filling with a gas in expand a volume space (1), such that when expanding the respective Hüllelementes (7, 7 ', 17, 17'), the openings (8, 8 ') of the Hüllelementes (7, 7', 17, 17 ') increase and the contents (12) of the enveloping element (7, 7 ', 17, 17') are delivered through the enlarged openings (8 ') of the enveloping element (7', 17 ') into the volume space (1), and with at least one first and one a second means for filling the Hüllele 7, 7 ', 17, 17'), wherein upon receipt of a triggering signal the first device is designed to at least partially fill the first enveloping element (7, 7 ') with nitrogen gas, and wherein the second device is configured, upon receipt of a trigger signal, the second envelope element (17, 17 ') at least partially filled with carbon dioxide gas, so that at least partially nitrogen gas as the content of the first Hüllelementes (7, 7') and at least partially carbon dioxide gas as the content of the second Hüllelementes (17, 17 ') is discharged into the volume space (1). Furthermore, the present invention relates to an installation space with a device according to the invention and a method for providing safety measures for gas release from a vehicle battery. |
