Embodiment Construction

[0035] figure 1 and figure 2 A lead frame 10 according to the invention is shown schematically. The lead frame is produced in one piece from the base material and has a surrounding frame section 20 . The frame section 20 is divided into corresponding nine module receptacles 40 by a number of eight individual dividing sections 30 .

[0036] as in figure 2 As can be seen in , two sealed boundaries can be seen. Here, on the one hand, it is an inner sealing means 60 which surrounds each of these module receptacles 40 . To this end, the inner sealing means 60 extend partly through the frame section 20 and partly through the corresponding partition section 30 . Furthermore, external sealing means 50 are provided, which are arranged only in the frame section 20 . Thus, the outer sealing means 50 encloses the entire frame section and acts as a second outer barrier preventing the passage of fluid from the outside inwards into the installation space of the electrical component. ...

Abstract

A lead frame (10) for a battery device (100) of an electric vehicle, the battery device (100) for the electric vehicle, and a method of manufacturing the battery device (100) are provided. The lead frame has an encircling frame section (20) and at least one separating section (30) that subdivides the frame section (20) into at least two module receptacles (40) for receiving in each case one cell module (120). The encircling frame section (20) has an encircling outer seal (50) for sealing off against the passage of liquid. Additionally, the at least one separating section (30), together with the frame section (20), has an inner seal (60) that encircles each module receptacle (40) for sealing off against the passage of liquid.

Description

technical field [0001] The present invention relates to a lead frame for a battery device of an electric vehicle, a battery device having such a lead frame, and a method for manufacturing such a battery device. Background technique [0002] It is known to equip electric vehicles with battery devices to provide electrical energy for driving the electric vehicles. Such battery devices have a plurality of individual battery cells. In order to improve the structure and simplify the assembly, the individual battery cells are usually assembled into so-called unit modules. A plurality of such unit modules are combined together in a battery frame for a battery device. [0003] The disadvantage of the known solutions is that the individual battery cells must be tempered during operation of the electric vehicle. This is in particular the cooling of the battery cells. A cooling liquid is usually used for this, which is generally electrically conductive and must therefore be spatial...
