Embodiment Construction

[0039] exist figure 1 A battery cell 10 is schematically shown in image 3 In the same schematically shown battery 26. For this purpose, the battery cells 10 can be designed, for example, as lithium-ion battery cells. In a battery 26 , which is used, for example, as a traction battery for a motor vehicle, a plurality of such battery cells 10 are usually electrically connected in series and / or in parallel in order to provide a correspondingly high voltage and high current.

[0040] When such battery cells 10 are connected in series, very high voltages of the battery 26 , even voltages of several hundred volts, can occur overall, for example because a plurality of battery modules each containing a plurality of battery cells are electrically conductively connected to one another. 10. However, such high voltages and the occurrence of short circuits or arcs can be dangerous for persons. This risk is avoided or reduced, for example, during the manufacture of the battery 26 . Th...

Abstract

The invention relates to a method for manufacturing a battery for a motor vehicle, in which electrical terminals (20, 22) of a plurality of battery cells (10) are connected by means of at least one electrically conductive connection element (30). The battery cells (10) have a galvanic element (14) accommodated in a battery cell housing (12) of the respective battery cell (10). The battery cells (10) are connected in such a way that the battery supplies a rated voltage which is greater than the rated voltage of one of the battery cells (10). To this end, after the connecting the electrical terminals (20, 22) of at least two battery cells (10), at least one switching element (24) of one of the battery cells (10) is changed to a switching state in which an electrically conductive connection is produced between a surge diverter (16) of the galvanic element (14) and at least one of the electrical terminals (20, 22) of the battery cell (10). The invention further relates to a battery and to a motor vehicle.

Description

technical field [0001] The invention relates to a method for producing a battery, wherein the electrical connections of a plurality of battery cells are connected by means of at least one electrically conductive connecting element, the battery cells having a battery cell accommodated in a battery cell housing of the respective battery cell. electrical components. The connection is designed such that the nominal voltage provided by the battery is greater than the nominal voltage of one of the battery cells. Furthermore, the invention relates to a battery for a motor vehicle and a motor vehicle. Background technique [0002] It is known from the prior art, for example DE 10 2010 045 037 A1, to form a battery from a plurality of battery cells for supplying a certain voltage or a certain current. Batteries of this type are today installed, in particular as traction batteries, in motor vehicles, for example electric vehicles or hybrid vehicles, for providing electric drive ener...
