Abstract: An over-molded printed circuit board may be used in a battery pack. The over-molded printed circuit board can include a printed circuit board having electronic components, such as battery management circuitry, disposed thereon. A flex connector can be attached to the printed circuit board. An over-mold can formed about the printed circuit board, for example, by injection molding an epoxy resin, polyamide, or other suitable material. The over-mold may facilitate routing of the flex connector at a desired angle from the battery back and may also have a geometry that provides a supporting mechanical interface between the cells of the battery pack and the printed circuit board. Battery packs so constructed may be installed in electronic devices, such as mobile telephones, smart phones, tablet computers, laptop computers, media players, etc.

Abstract: A battery pack is disclosed. The battery pack includes a cell with a spacer, and a cap mounted on the spacer. The spacer and cap are mated to form a cavity to accommodate the components (i.e. busbars, circuit board, an insulator) of the battery pack. The spacer and cap have a series of mating surfaces for the components, wherein the mating surfaces have different heights to be recessed relative to each other to create spaces for accommodating the components. The recesses, channels, steps and raised portions correspond in geometry to the components so that they can be assembled while removing the tolerance accumulation associated with multiple standoffs.

Abstract: A streamlined battery pack can contain at least two battery cells. A printed circuit board (PCB) of the battery pack can include a protection control module. The PCB can have castellations along its perimeter in which wires are soldered. The wires can include battery power wires and battery monitoring signal wires. The castellations are sized so that the egress wires can be soldered therein without substantially protruding from the outline of the PCB. The PCB has a surface area that is no greater than an end of the battery pack, and thereby need not exceed the outer diameter of the remainder of the battery pack. The PCB and the other battery pack components may be substantially enveloped in a polyimide material. The components of the battery pack, including the PCB can arranged, sized and configured, such that they do not create protuberances in the enveloping material.
