Abstract

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.

First claim

1 . A battery system, comprising:
at least one battery apparatus, having at least one safety apparatus configured to increase safety when using a degassing apparatus, wherein the degassing apparatus is configured to degas battery apparatuses in a controlled manner, and wherein the battery apparatus and the safety apparatus are surrounded by a housing and the degassing apparatus is inserted into a wall of the housing, wherein the safety apparatus produces a gap between the battery apparatus and the degassing apparatus in such that a space is kept free between the battery apparatus and the degassing apparatus so as to dissipate substances that escape from the battery apparatus in an area surrounding the battery system.

2 . The battery system as claimed in claim 1 , wherein the gap is between 0.001 m and 0.1 m.

3 . The battery system as claimed in claim 1 , wherein:
the degassing apparatus is one of a bursting disk, a bursting membrane, a bursting valve, and an excess pressure valve; and the degassing apparatus is configured to be opened by one of an effect of a force and exerting a pressure; and the degassing apparatus is configured to dissipate substances from the battery apparatus into the area surrounding the battery system.

4 . The battery system as claimed in claim 1 , wherein:
the at least one safety apparatus is configured to increase safety when using a degassing apparatus so as to generate a force effect on the degassing apparatus in dependence upon a state of the battery apparatus; and the effect of the force causes the degassing apparatus to open.

5 . The battery system as claimed in claim 1 , wherein:
the at least one safety apparatus is configured to increase safety when using a degassing apparatus so as to exert a pressure on the degassing apparatus in dependence upon a state of the battery apparatus; and exerting the pressure opens the degassing apparatus.

6 . The battery system as claimed in claim 1 , wherein the at least one safety apparatus is open for substances that escape from the battery apparatus.

7 . The battery system as claimed in claim 1 , wherein the at least one safety apparatus is electrically insulated.

8 . The use of a battery system as claimed in claim 1 in a vehicle.

9 . The battery system as claimed in claim 2 , wherein the gap is between 0.005 m and 0.015 m.

10 . The battery system as claimed in claim 3 , wherein the pressure is between 2 bar and 10 bar.

11 . The battery system as claimed in claim 4 , wherein the at least one safety apparatus is configured to increase safety when using a degassing apparatus so as to generate a force effect on the degassing apparatus in dependence upon at least one of a physical change of the battery apparatus and a pressure that prevails within an interior of the battery apparatus.

12 . The battery system as claimed in claim 5 , wherein the at least one safety apparatus is configured to increase safety when using a degassing apparatus so as to exert a pressure on the degassing apparatus in dependence upon at least one of a physical change of the battery apparatus and a pressure that prevails within the interior of the battery apparatus.

13 . The battery system as claimed in claim 5 , wherein the at least one safety apparatus is configured to exert a pressure of between 2 bar and 10 bar.

14 . The battery system as claimed in claim 8 , wherein the vehicle is a motor vehicle.
