Zusammenfassung:	A battery pack for use in a vehicle may comprise battery cells, with each of the battery cells including a main body and a foil cell tab extending from the main body, with the battery cells arranged into a first set and a second set; an interconnect having a first leg, a second leg, and a bridge connecting the legs; first weld locations securing the foil cell tabs of the first set of battery cells to the first leg; and second weld locations securing the foil cell tabs of the second set of battery cells to the second leg. The foil cell tabs or the legs of the interconnect or both may include relief slots extending between the weld locations. Also, the thickness of a set of the tabs may be equal to the thickness of the leg to which they are welded.
