Embodiments include a portable rechargeable battery pack, system, and external adapter that allow the portable rechargeable battery pack to both power a host device though a set of host contacts and provide power through a set of charging contacts. The portable rechargeable battery pack includes a charge protection circuit that prevents an excessive discharge current through the charging contacts and allows high charge current when charging the portable rechargeable battery pack. A discharge circuit allows a low level discharge current through the charging contacts to provide power to other devices.

Portable rechargeable battery pack and external adapter for same

A battery connector system for connecting a battery to a battery powered device is provided herein that includes an insert molded contact block comprising a contact block, a plurality of electrical contacts insert molded into the contact block, and an outer electrical connection for electrically coupling the plurality of electrical contacts to the battery powered device. The battery connector system further includes an inner electrical connection located on a housing enclosure for electrically coupling the battery housed in the housing enclosure to the outer electrical connection through the plurality of electrical contacts. The battery connector system further includes a sealed electrical path between the inner electrical connection and the outer electrical connection, wherein the sealed electrical path is formed by over molding the insert molded contact block with the housing enclosure.

Battery connector system

An electronic device and battery are presented. The electronic device includes the battery, which has a first latch. The first latch has an arm and a hook. The arm is connected with the battery at a connected end and the hook at a free end opposed to the connected end. The hook forms a peak and a base connected with the free end. The base forms an inwardly projecting groove. The electronic device also includes a device housing forming a main cavity bound by first and second side surfaces, a rear surface and a bottom surface. The first side surface includes a ledge for receiving the groove and defines a latch cavity for receiving the first latch. In an engaged position, the peak extends into the latch cavity and the groove engages the ledge.

Inertia enhanced latching system

An interconnect assembly () includes a spring member () integrally formed of a first portion () having two prongs () and a slot (), the first portion being coupled to a second deflected portion () formed of a cantilevered beam () with interference fit tabs () extending from either side. A latch () includes hooks () and foot members (). A housing (), such as a battery pack housing, includes a side surface () having protrusion () and pockets () formed therein along with vertical side channels (). The spring, latch and housing () are coupled such that the vertical channels () capture and guide the interference fit tabs () down the side of the housing () as the foot members () of the latch () are inserted into the pockets () of the housing (). As the spring member () is pushed downward, the protrusion () of the housing () captures the slot (), and the hooks () of the latch () capture the interference fit tabs () of the spring member thereby providing a locked latch-spring assembly ().

Interconnect assembly

An improved electrical interconnect member for rechargeable battery packs is provided. The interconnect member includes a metal tab and a plastic housing. The metal tab preferably includes side bends projecting below the tab in a non-perpendicular geometric orientation with the top of the tab. The tab includes at least one lance for preventing post-assembly, lateral movement between the tab and housing. The housing is preferably Y-shaped, with the outer surfaces of the Y having concave curvatures. The concave curvatures allow the housing to seat between adjoining, cylindrical cells. The housing includes a rail with a cross section that corresponds to the area between the side bends and the top of the tab. The housing also includes a post for coupling to the lances.

Interconnect for rechargeable computer batteries

This invention includes a battery pack capable of attaching to an ordinary belt. The battery pack includes springy, U-shaped clips that are capable of coupling to objects such as belts. The clips are coupled to the battery pack by way of ball and socket joints, thereby allowing the battery pack to be mounted at any of a number of angles, including horizontal and vertical configurations. The battery pack optionally includes a torso accommodation curve to make the battery pack more comfortable for the user.

Detached portable battery with universal clip

This invention includes a charger that may be mounted either in a horizontal configuration, e.g. on a desktop, or in a vertical configuration, e.g. on a wall. The charger has pockets geometrically oriented so as to support batteries in either configuration. Each pocket includes a corresponding display. As changing from a desktop configuration to a wall mount configuration requires the user to rotate the charger by 180 degrees, a switch is provided to rotate the information shown on the display by 180 degrees. The switch is preferably recessed below the surface of the charger so as to prevent nuisance actuation. The resulting orientation of the display is stored in a non-volatile memory to prevent resets when power is removed. By holding the switch down for a predetermined amount of time, a user can send the display into a test mode so as to run diagnostics and verify proper display operation.

Battery charger

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.

Interconnect system for rechargeable computer batteries

This invention includes an electrically-conductive contact, preferably for use in battery chargers. The contact is manufactured from a springy metal material, like stainless steel. The contact includes a triangular shaped contour, capable of withstanding battery insertion force, and further capable of mating to battery contacts of varying depths. The contact includes a mechanical stop for preventing the contour from protruding too far through apertures in the battery charger pocket. A stem preloads the mechanical stop against a retaining wall. A lanced barb on a charger mount allows the contact to reside in the charger without the need of other adhesives, screws or rivets. A protrusion makes contact with an electrical pad on a printed circuit board. A protrusion extensor preloads the protrusion against the pad.

Battery for a laptop computer

A foil battery packaging containing a battery cell is described wherein the tab comprises a strong metal tab secured to the packaging, and wherein the strong metal tab is electrically connected to a weak metal tab of the battery cell. The packaging may also comprise a metal reinforcing strip secured to the strong metal tab, the weak metal tab, and the battery packaging.

Battery tab

A battery packaging system (10) packages a battery cell or cells (26) in a housing member (12). A clip (14) is used to retain the battery cells in the housing member, and has cantilevered clip fingers (32) which engage openings (22) formed on the rim (20) of the housing member. The clip compressionally or resiliently engages the battery cells, so that they are tightly held in the housing, by retaining fingers (40) formed in the retaining surface (28) of the clip. A cap (16) may be attached to the clip, and provides a peripheral skirt (54) which covers the openings so that the clip is not removable.
