Abstract
A battery pack with a compact and robust bus bar assembly is provided. The batteries within the pack are divided into groups, where the batteries within each battery group are connected in parallel and the groups are connected in series. A repetitive sequence of overlapping bus bars is used, with each bus bar comprised of upper and lower segments coupled together via a step segment. The overlapping design allows the upper surface of the upper segment of each of the repetitive bus bars to be aligned within an upper plane, and the lower surface of the lower segment of each of the repetitive bus bars to be aligned within a lower plane.
