The invention relates to a battery housing for receiving at least one battery unit () comprising a first housing wall () and a second housing wall (), characterized in that the first housing wall () forms a first securing element () and the second housing wall () forms a second securing element () which are formed in such a way that the first securing element () and the second securing element () are reversibly connected to one another for fixing the first housing wall () relative to the second housing wall ().

Battery housing, battery comprising a battery housing of this type, sheet element for producing a battery housing of this type, and method for producing a battery housing of this type

A module housing () for a battery module () having at least one battery cell () exhibiting a first substantially L-shaped housing side wall () with at least one clip connection (), and a second substantially L-shaped housing side wall () with at least one clip connection () and two housing plates () which can be arranged on the battery module () on the end face, as a result of which the module housing is closable on the end face. At least the two housing side walls () can be connected to one another mechanically in a form-fitting and/or force-fitting manner by means of clip connections (), as a result of which a cuboid module housing () can be produced.

Module housing for a battery module

A method for insulating a battery module () which has a multiplicity of battery cells (), having at least one foldable insulation element (), having at least the following steps:

Method for insulating a battery module

A cell connector for connecting lithium-ion battery cells of a lithium ion battery includes a body and a fuse.

Cell connector for a battery system or for a battery cell of an electrical energy store, battery and motor vehicle

A motor vehicle battery has a plurality of battery modules (). Each battery module () is fastened to housing walls () of a battery housing (). The battery housing () has at least two housing modules () positioned above one another and formed with housing module walls (). At least some of the mutually adjoining housing module walls () interengage in the manner of toothing to form the housing walls ().

Motor vehicle battery

A battery system comprises a battery which includes a plurality of battery cells connected in series and two battery poles. The battery system further comprises at least one protection device, which is connected to the battery cells in series in such a manner that after the at least one protection device is tripped, a sum of voltages of the battery cells still connected in series does not exceed a limit voltage. The battery system also comprises a switching device which electrically connects the two battery poles, the switching device being configured to short-circuit the battery when a fault signal is detected, thus tripping the at least one protection device.

Battery system and motor vehicle

A motor vehicle battery has at least one battery module with a plurality of battery cells () that have connection poles and degassing predetermined breaking points (). The battery module also has a common battery module control device () for all of the battery cells () of the battery module. The degassing predetermined breaking points () of the battery cells () are on one side of the battery module and are offset inward in relation to the connection poles of the battery cells to form a recess (). A guide element () is positioned in the recess () and extends along all of the battery cells () of the respective battery module to define a degassing channel () on one side and defining an accommodation space () for the battery module control device () on the other side.

A motor vehicle battery has at least one battery module () with a plurality of battery cells () bounded by battery module walls () of the battery module (). Two opposite battery module walls () of the battery module () are between walls () of a battery housing or walls of a bodywork structure. Deformation elements () fasten the battery module walls () of the respective battery module () indirectly to walls () of the battery housing or of the bodywork structure, and the respective wall () of the battery housing or of the bodywork structure.
