Embodiment Construction

[0033] figure 1 A portion of a first battery cell 20 is shown, with terminals 21 provided on its surface. A cutout 24 is formed in the terminal 21 , in which cutout the cell connector 10 is positioned. The cell connector 10 is conductively connected to the terminal 21 by means of a fillet weld 25 .

[0034] The width W of the cell connector 10 is preferably dimensioned in such a way that the cell connector 10 can be accommodated in the recess 24 in the terminal 21 with a substantially precise fit.

[0035] In order to obtain a battery cell module composed of battery cells 20 , at least two battery cells 20 are electrically conductively connected via a cell connector 10 in the manner shown.

[0036] exist figure 2 shown in figure 1 A plan view of a detail of a battery cell 20 is shown. It is shown here that the cell connector 10 is severed at the cutting edge 26 , so that it still only forms a cell connector remainder 23 . The remainder 23 of the cell connector is electr...

Abstract

The invention relates to a cell connector, a battery cell module with a cell connector according to the invention, a method for producing a battery cell module, a battery with at least one battery cell module and a battery A motor vehicle with the battery cell module and / or the battery. A cell connector (10) for electrically connecting at least two battery cells (20, 20a) and comprising at least two for supporting the cell connector on terminals (21) of the battery cells (20, 20a) Bearing surface (12). These support surfaces (12) are arranged front and back on the longitudinal extension direction (11) of the cell connector (10) and are arranged on one side of the cell connector (10), wherein the cell connector (10) is on the support surface (12) have a lateral offset therebetween such that the support surfaces are laterally offset relative to each other.

Description

technical field [0001] The invention relates to a battery cell connector, a battery cell module comprising a battery cell connector according to the invention, a method for manufacturing a battery cell module, a battery comprising at least one battery cell module and a battery cell module A motor vehicle with battery cell modules and / or batteries. Background technique [0002] There are many demands on batteries for a wide range of applications, for example for vehicles, stationary installations such as, for example, wind power plants, and mobile electronic devices, such as notebook computers and communication devices. High demands are placed on such batteries in terms of reliability, service life and capacity. [0003] Lithium-ion technology is specific to a wide range of applications. It is characterized in particular by a high energy density and an extremely small self-discharge. [0004] Such lithium-ion battery cells generally comprise electrodes which enable the rev...
