In an aspect, the contact plate arrangement includes a busbar configured to transport current between first and second parallel groups of battery cells (P-Groups) in series, and a bonding connector attached to a sidewall of the busbar and configured to form an electrical connection with a cell terminal of a battery cell from a respective one of the first and second P-Groups.

One aspect relates to a method for producing a heat-spreading plate for a circuit carrier. At least one first layer made of a first material having a first coefficient of expansion and at least one second layer made of a second, low-stretch material having a second coefficient of expansion that is smaller than the first coefficient of expansion are bonded to each other at a bonding temperature of 150° C.-300° C. by means of a low-temperature sintering process. At least one bonding layer from a bonding material is formed between the first layer and the second layer and the bonding temperature essentially corresponding to the mounting temperature at which the produced heat spreading plate is connected to at least one circuit carrier.

A method of assembling a first part made from a metal and a second part includes providing a first part comprising an assembly surface, and a second part comprising at least one through orifice. At least part of the second part is arranged on the assembly surface such that the orifice extends across from the assembly surface. A metal connecting part is positioned on the orifice to cover the orifice across from the assembly surface. The connecting part and/or the assembly surface are projected on one another to obtain high-speed plating and welding between the connecting part and the surface part.
