AI Technical Summary

Problems solved by technology

Overcharge additives also lead to a slow, continuous increase in the pressure in the cell housing
This can lead to undesired triggering of the current interruption device over time, especially at unpredictable times

Embodiment Construction

[0053] exist image 3 A modified battery cell 24 is schematically shown in FIG. 2 , which likewise has a current interruption device. The battery cells 24 can be used, for example, in a battery of a motor vehicle and are designed, for example, as lithium-ion battery cells. In batteries such as those used as traction batteries for motor vehicles, usually a plurality of such battery cells 24 are electrically connected in series and / or in parallel in order to provide correspondingly high voltages and currents.

[0054] During the operation of the battery cell 24 , situations can now arise in which it is advantageous to connect the electrical element 26 of the battery cell 24 to at least one of the two electrical connections 28 , 30 of the battery cell 24 . The current flow through the electrical connection can be interrupted. This can be used in image 3 This is ensured by the switchable and intelligent battery cells 24 schematically shown in .

[0055] The battery cell 24 incl...

Abstract

The invention relates to a battery cell (24) for a battery of a motor vehicle having a battery cell housing (32) in which a galvanic element (26) is accommodated. The battery cell (24) comprises two electrical terminals (28, 30), via which the battery cell (24) can be electrically connected to at least one further battery cell of the battery. At least one switching element (38) is changed by means of a control unit (40) to a switching state in which an electrically conductive connection between a surge diverter (34) of the galvanic element (26) and at least one of the electrical terminals (28, 30) is interrupted. The invention further relates to a battery having a plurality of such battery cells (24) and to a motor vehicle having a battery.

Description

technical field [0001] The invention relates to a battery cell for a motor vehicle battery. The battery cells comprise a battery cell housing in which electrical / electrochemical elements are accommodated. Via the two electrical connections, the battery cell can be electrically connected to at least one further battery cell of the battery. Furthermore, the invention relates to a battery having a plurality of such battery cells and a motor vehicle having a battery. Background technique [0002] It is known from the prior art, for example from document DE 10 2010 045 037 A1, to connect a plurality of battery cells to form a battery in order to supply a certain voltage or a certain current. Such batteries are used today in particular as traction batteries in motor vehicles, such as electric vehicles or hybrid vehicles, for providing electric drive energy. [0003] A so-called current interrupt device (CID, Current Interrupt Device) can be provided in such a battery cell. Suc...
