Abstract: A battery pack is provided that can better manage peak current of in a converged portable radio. The battery pack comprises an internal Li-Ion cell stack characterized by a linear output voltage curve. A DC-DC converter converts the internal cell stack voltage to a desired DC-DC converter output voltage. The output voltage and current sourcing capability of the battery pack remain constant over the full cell discharge curve. The battery pack optimizes cell utilization, without the use of any internal microprocessor, thereby supporting the operation of simultaneous high peak current application features associated with LMR and LTE.

Abstract: A method for charging a battery includes detecting, with an electronic processor, a presence of the battery coupled to a charging interface. The method includes receiving, with the electronic processor, a command, the command including a charge mode. The method includes, in response to receiving the command, controlling a charging circuit coupled to the charging interface to charge the battery to a predetermined level based on the charge mode. The method includes, when the battery reaches the predetermined charge level, sending a battery control command, based on the charge mode, to control an active limiting circuit of the battery via a single wire data line coupled to the charging interface.

Abstract: A method and apparatus for visually indicating battery pack information related to wirelessly charging a battery pack via a wireless charging mat. The method includes uniquely associating, with a controller of the wireless charging mat, each visual indicator of a first plurality of visual indicators on the wireless charging mat with one of a first plurality of sensors on the wireless charging mat. The method further includes receiving the battery pack information from the battery pack with one or more of the first plurality of sensors. The method further includes wirelessly charging the battery pack using the wireless charging mat, and illuminating the first plurality of visual indicators based on the battery pack information.

Abstract: A latch apparatus is formed of a cantilevered beam (202) and a button (204). The cantilevered beam (202) comprises a loading feature (210) and a notch (216), while the button (204) comprises a slot (218) and an engagement tab (220). When mounted within a cavity of a housing, the cantilevered beam and button provide both push-in and side sliding movement of the button. The latch is locked by sliding the button in one direction, and the latch is unlocked by pushing the button inward and then sliding the button in an opposite direction. The housing may further comprise an angled catch feature within the cavity for mating with a complimentary angle of the button to avoid inadvertent unlocking of the latch. The combination of push in force and side sliding force minimizes inadvertent unlocking of the latch assembly.

Abstract: An apparatus, system and method for wirelessly charging are provided within a vehicular environment. The wireless charging system comprises a seatbelt receptacle containing a transmit coil integrated therein for transmitting a charging signal to a battery or powering a battery operated device. A repeater coil can be wirelessly coupled to the transmit coil via the seatbelt's buckle, as a buckle repeater coil or a retrofit cover repeater coil. Additional repeater coils may be added to a shoulder strap, a lap strap, or other portions of the seat belt harness for additional charging points. The additional repeater coils are slideable to adjust for different body sizes. One or more portable devices having receive coils can be charged or powered wirelessly from the transmit coil in the seatbelt receptacle, the repeater coil of the seatbelt buckle or cover, and/or the additional adjustable strap repeater coils.
