Abstract
A method of manufacturing a battery pack including the creation of a support board for enabling conversion of the battery pack from providing a first voltage to providing a second voltage. The support board is created by injection molding about a precut set of power traces for coupling a converting element to a plurality of battery cells. The power traces couple the plurality of battery cells to a set of battery pack terminals. The support board may be mechanically coupled to a battery cell holder.
Claims6
A method of manufacturing a battery pack, comprising the steps of:
- cutting a trace layout from a sheet of material, the trace layout including at least one trace;
- bending the at least one trace to provide a set of terminal flags;
- placing the trace layout in an injection mold;
- injecting a plastic material into the injection mold to form a support board having a planar surface that is approximately perpendicular to the set of terminal flags, such that a portion of the at least one trace remains exposed to present a plurality of contact pads at a position remote from a respective terminal flag and in the planar surface of the support board;
- providing a set of battery cells;
- providing a battery cell holder for holding the set of battery cells;
- mechanically coupling the support board to the battery cell holder;
- and
- electrically coupling the at least one trace to the set of battery cells.
