Abstract: A switching-mode power system and method utilizing a rechargeable primary higher-current density energy cell and a rechargeable secondary lower-current density cell are disclosed. The system and method employ a collection of switches that are dynamically actuated so as to selectively interconnect and repurpose a minimal arrangement of components. This facilitates the selective provision of power to a portable device or system from a rechargeable primary high-current density energy cell or a rechargeable secondary lower-current density cell.

Abstract: The present technology relates to systems and methods for rapidly charging a battery of a device when the device is attached to an AC adapter. Some embodiments of the present disclosure describe an activation circuit in an AC adaptor and a detection circuit in a downstream device that cooperatively ensure optimal power delivery. Some embodiments of the present disclosure describe a device with a system load, a battery, and a control circuit, wherein the control circuit is configured to provide the battery with a charging current of Ibat=Imax?Isys when the device is in a USB compliant mode of operation and a charging current of Ibat=Imax when the device is connected to an AC adapter.
