Abstract:
1. An intelligent battery power delivery apparatus, comprising: input terminals receiving power from one or more battery cells; output terminals for providing power to a load; and, a conversion module configured to maintain output power characteristics at the output terminals according to programmed characteristics, and configured to control power draw at the input terminals according to the programmed characteristics; wherein the conversion module comprises a digital circuit, the digital circuit comprising: a DC to DC voltage conversion unit; a current sense unit; a fuel gauge; and a central processing unit; wherein the DC to DC voltage conversion unit is adapted to provide a programmed voltage to the load, wherein the current sense unit is adapted to obtain a sensed current from the one or more battery cells and to utilize the sensed current for functioning of the fuel gauge unit, wherein the fuel gauge unit monitors a state of charge of the one or more battery cells and reports the state of charge to the central processing unit to prevent overcharge or over-discharge of the one or more battery cells, and wherein the central processing unit manages digital power conversion by the conversion module.
