A method and apparatus for a unitary battery and charging circuit that in cludes a first substrate having integrated-circuit battery-charging circuitr y thereon, and a cathode material, an anode material, and an electrolyte lay er separating the cathode material from the anode material deposited on the substrate to form a battery, wherein the charging circuit is connected to th e battery and encapsulated to form a surface-mount unitary package. Also, a power conversion system that includes a variable charging source and an ener gy storage device. The power conversion system also includes a charging circ uit coupled to the variable charging source and the energy storage device, t he energy storage device being charged by the variable charging source. Furt her, the system includes an energy storage device isolation circuit configur ed to isolate the energy storage device from discharging when power from the variable charging source is below a predetermined threshold. Further still, the conversion system includes a restart circuit configured to restart the charging system by utilizing power from the energy storage device when charg ing power has dropped below a predetermined level. |
