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.

Apparatus for increasing safety when using battery systems

The invention relates to a holding-down means () for fixing battery cells () in a battery submodule (), comprising positioning elements for positioning the holding-down means () relative to the battery cells (), and comprising guide elements for guiding cell connectors () which connect the battery cells (), wherein gas-venting openings which pass through from a top side to a bottom side are provided in a central region of the holding-down means (), and wherein the sealing elements which surround the gas-venting openings are provided on the bottom side of the holding-down means (). The invention also relates to a battery submodule () which comprises a plurality of battery cells () and cell connectors () which connect the battery cells (), and also at least one holding-down means () for fixing the battery cells ().

A method of producing a prismatic battery cell includes forming an initial arrangement by spatially arranging one or two wiring boards, a cathode layer, an anode layer, and at least two separator layers so as to be in parallel with each other and with respect to a winding axis. The initial arrangement is wound about the winding axis to form a battery winding. The battery winding is inserted in a cell housing, and a respective current connector is connected to each of the cathode layer and anode layer. The cell housing is filled with a liquid electrolyte, and is closed. A prismatic battery cell of this type can be included in a battery, such as a battery included with an automotive vehicle.

Method of producing a prismatic battery cell

A battery system (BS), containing at least one battery device (BV) and at least one operating device (BTV) for operation of the battery system (BS) and/or of the at least one battery device (BV), and at least one further device (V), wherein the at least one further device (V) is intended to create a physical distance between two component parts of the battery system (BS) and in particular between the at least one battery device (BV) and a further component (K) of the battery system (BS), or between at least two component parts of the at least one battery device (BV), wherein the at least one operating device (BTV) is arranged at least partially within the at least one further device (V).
