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.
Claims20
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 an 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 input source;
- and
- 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.
A method for supplying cordless power from a portable power supply system, the method comprising:
- at a first power supply unit, sensing whether a second power supply unit is coupled to the first power supply unit;
- if the second power supply unit is sensed to be coupled to the first power supply unit, then receiving electrical energy at a first energy storage device, via a first switch, from the second power supply unit;
- whereas
- if the second power supply unit is sensed to not be coupled to the first power supply unit, then receiving electrical energy at the first energy storage device, via the first switch, from an input source;
- and
- at the first power supply unit, sensing whether a third power supply unit is coupled to the first power supply unit;
- if the third power supply unit is sensed to be coupled to the first power supply unit, then directing electrical energy from the first energy storage device, via a second switch, to the third power supply unit;
- whereas
- if the third power supply unit is sensed to not be coupled to the first power supply unit, then directing electrical energy from the first energy storage device, via the second switch, to an output destination.
A portable power supply system for providing cordless electric power, the portable power supply system comprising:
- a supply means for supplying electrical charge, wherein the supply means derives the electrical charge from a plurality of charge sources;
- a controlling means for controlling the supply means and for delivering the electrical charge from one or more of the plurality of charge sources to the portable power system;
- an energy storing means for storing the electrical charge delivered by the charge controlling means, wherein the energy storing means is coupled to the charge controlling means using a first switching means, further wherein the first switching means enables the energy storing means to derive additional electrical charge from a second portable power system;
- a sensing means for determining whether the second portable power system is coupled to the first portable power system;
- a sensing means for determining whether a third portable power system is coupled to the first portable power system;
- and
- a switching means for supplying electrical energy from the energy storing means to the third portable power system or to an inverting means for converting electrical energy to an alternating electric current, wherein the inverting means is connected to an output destination.
