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...
