Abstract
This invention includes an improved interconnect assembly for use in rechargeable battery packs for laptop computers. The invention eliminates manufacturing defects resulting from the hand soldering processes of the prior art. The assembly provides interconnection for rechargeable cells oriented end to end, in parallel rows. Insulated runners provide interconnection to a bus located along the center of the end to end cells. The bus is a flexible circuit that couples to a printed circuit board. In one preferred embodiment, the bus is less than two inches in diameter and less than the diameters of the parallel rows of end to end cells in length. The assembly eliminates the need for hand soldering, eliminates cumbersome wire routing, and offers multiple insulation features that prevent electrical shorts.
