Abstract: A method and apparatus for a battery protection circuit. One embodiment provides a method for protecting a battery including receiving, with a comparator, a first voltage, the first voltage including a switch voltage across a current limiting switch provided on a current path of a battery and coupled to a current limiting control circuit to limit current output by the battery. The method also includes receiving, with the comparator, a reference voltage and comparing, with the comparator, the first voltage and the reference voltage. The method further includes controlling, with the comparator, a control switch to open when the first voltage exceeds the reference voltage.

Abstract: Disclosed herein are methods and systems for contactless battery discharging. One embodiment takes the form of a contactless power-transfer system that includes a wireless-communication interface, a controller connected to the wireless-communication interface, a magnetic-resonance circuit, a power-conditioning circuit connected to the magnetic-resonance circuit, and a load element connected to the power-conditioning circuit. The controller is configured to determine that a smart-battery system is in a discharge-needed state and responsively transmit, via the wireless-communication interface, a battery-discharge command instructing the smart-battery system to generate an oscillating magnetic field. The magnetic-resonance circuit is configured to couple with the generated oscillating magnetic field and responsively output a corresponding power signal. The power-conditioning circuit is configured to receive the power signal from the magnetic-resonance circuit, rectify the received power signal, and output the rectified power signal. The load element is configured to receive the rectified power signal from the power-conditioning circuit.

Abstract: Body-worn wireless electronic devices may be powered by one or more wireless power sources. These wireless power sources may comprise body-worn wireless power sources and non body-worn wireless power sources. The sources are detected by the electronic device and are either prioritized based on being body-worn or non body-worn. The selection of sources for powering the electronic device(s) may alternatively be made based on predetermined parameters associated with the power sources. Optimal power transfer is thus obtained for the electronic devices while being worn.
