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. In addition, by selectively actuating the switches, the switching-mode power supply is enabled to a) permit the secondary lower-current density cell to quickly attain a charge level suitable for device/system operation when connected to a charging station/power source, b) charge the primary high-current density energy cell, and c) employ the charged secondary lower-current density cell to charge the primary high-current density energy cell when disconnected from the charging station/power source.
