Claim 14:
15. A method for constructing a battery pack for use with a heat sink having a bracket joined thereto, wherein the bracket includes a pair of side walls extending outwardly away from the heat sink such that the bracket defines a bracket pocket between the side walls, the method comprising:
arranging a plurality of busbars in parallel, wherein each of the busbars is constructed from a plate of an electrically conductive material, and has a respective first distal end and a respective second distal end;
overmolding a dielectric material of a plastic interconnect board (ICB) onto the respective second distal end of each of the busbars to form a plurality of overmolded ends;
attaching the respective first distal end of each of the busbars to the plastic ICB to thereby form an ICB assembly of the battery pack;
providing a plurality of battery cells, wherein each respective battery cell of the plurality of battery cells has battery cell tabs that protrude as electrode extensions from one or more edges of the respective battery cell;
conductively joining respective battery cell tabs to respective busbars to form a plurality of cell-to-busbar joints;
connecting the bracket to the heat sink, the bracket defining the bracket pocket therein; and
inserting the plurality of overmolded ends into the bracket pocket to thereby engage the bracket, such that the overmolded ends extend into the bracket pocket between the side walls such that the overmolded ends are concealed by the side walls, and the respective overmolded ends form a cooling path between respective cell-to-busbar joints and the heat sink.
