Abstract:
1. A battery pack comprising: a plurality of bare cells; and a protective circuit module defining a first surface electrically connected to the bare cells, wherein the protective circuit module includes N pads, wherein each pad comprises a first half pad and a second half pad positioned adjacent to each other on the first surface of the protective circuit module so that the first half pad and the second half pad are co-planar and are spaced apart from each other so that a portion of the first surface of the protective circuit module is interposed between the first and second half pads which defines a gap, N is a natural number that is greater than 1, and the first half pad is electrically connected to the second half pad wherein the first and second half pads are formed of copper and each define a zig-zag edge that is separated by the surface of the protective circuit module so that the location of the gap between the first and second half pads is displaced across the width of the pad; and a plurality of leads plates that interconnect the plurality of cells to the plurality of first half pads; and a plurality of connectors made of solder that interconnect the plurality of first half pads to the adjacent plurality of second half pads so as to extend between the zig-zag edges wherein the plurality of connectors are deposited onto the portion of the first surface of the protective circuit module that is interposed between the first and second half pads.
