Abstract: A battery cell connector includes a plurality of segments. The plurality of segments includes: a first terminal segment with first connecting elements for a battery pole of a first battery cell; a second terminal segment with second connecting elements for a battery pole of a second battery cell; and one or more additional segments connecting the first terminal segment to the second terminal segment. Each additional segment defines a plane and has a longitudinal axis. The battery cell connector further includes a plurality of bends coupling the plurality of segments together into a 3-D object. Each bend is located between a unique pair of adjacent segments of the plurality of segments. The pair of adjacent segments defines two distinct respective planes. The first terminal segment is not parallel to the second terminal segment. The first connecting elements are electrically coupled with the second connecting elements.
