Abstract
A method and apparatus for supplying cordless power to a remotely-located load device. A first power supply unit of a portable power supply system is configured to operate in a charge receive mode and/or a charge supply mode. When the first power supply unit is in the charge receive mode, a first energy storage device of the first power supply unit is configured to receive electrical energy via a first switch from one of a second power supply unit or an external power source. When the first power supply unit is in the charge supply mode, the first energy storage device of the first power supply unit is configured to supply electrical energy via a second switch to one of a third power supply unit or a remotely-located load device.
Claims18
A portable power supply system, comprising:
- a first power supply unit, including:
- a first energy storage device configured to store electrical energy for the first power supply unit;
- a first switching mechanism configured to direct electrical energy to the first energy storage device from a first input source;
- and
- a second switching mechanism configured to direct electrical energy from the first energy storage device to an output destination;
- wherein the first power supply unit is configured to selectively operate in a charge receive mode and/or a charge supply mode;
- wherein, when the first power supply unit is in the charge receive mode, the first energy storage device is configured to receive electrical energy via the first switch from one of a second power supply unit or the first input source;
- wherein the second power supply unit includes a second energy storage device configured to store electrical energy for the second power supply unit;
- a third switching mechanism, configured to direct electrical energy to the second energy storage device from a second input source;
- and a fourth switching mechanism, configured to direct electrical energy from the second energy storage device to the first power supply unit;
- wherein the first input source is configured to selectively receive electrical charge from at least one of a first solar energy source or a first alternating current (AC) energy source;
- wherein, when the first power supply unit is in the charge supply mode, the first energy storage device is configured to supply electrical energy via the second switch to one of a third power supply unit or the output destination.
