Abstract
A multi-level busbar for interconnecting flexible cell tabs within a battery module of a battery electric system, e.g., of a motor vehicle having a traction motor and road wheels, includes first and second busbar surfaces and an elongated step transition. The first busbar surface is arranged at a first level of the busbar and is configured to be welded to a first tab group of the cell tabs. The second busbar surface is arranged at a second level of the busbar, and configured to be welded to a second tab group of the cell tabs. The step transition has a height dimension configured to allow the first and second tab groups to overlap when folded against and welded to the busbar.
