Abstract
The present invention is directed to a power source that includes a housing and an energy storage device arranged to provide an output power. A generator is disposed within the housing and is rechargeable association with the energy storage device.
Claims48
A power source for providing remote electrical power comprising:
- a transportable housing;
- an engine arranged within the transportable housing;
- an energy storage device disposed within the housing to provide an output power of the power source;
- a generator configured to be driven by the engine, disposed within the transportable housing, and arranged in rechargeable association with the energy storage device;
- a switchable electrical configuration arranged to switch delivery of output power between the generator and the energy storage device;
- and
- a controller configured to automatically switch the switchable electrical configuration to deliver the output power of the power source from one of:
- the generator, the energy storage device, and a combination of the generator and the energy storage device.
5 more elements
A method of portably providing remote electrical power comprising the steps of:
- initiating a power delivery from an energy storage device disposed within a portable housing;
- starting a fossil fuel driven engine power source disposed within the portable housing;
- and
- upon an energy level of the energy storage device reaching a lower threshold, automatically switching the power delivery from the energy storage device to the fossil fuel driven engine power source.
1 more element
An aircraft ground power apparatus comprising:
- an engine driven power source configured to generate electrical power;
- an energy storage device connected to the engine driven power source and configured to automatically and directly power an idle aircraft alternately with the engine driven power source.
An aircraft ground power device comprising:
- a housing;
- a generator disposed in the housing and configured to deliver power;
- an energy storage device rechargeably connected to the generator and configured to power an aircraft over a given duration;
- and
- a switch controller switchably connected to the generator and the energy storage device and configured to connect the generator to power the aircraft after the given duration.
2 more elements
A method of providing aircraft ground power comprising:
- powering an aircraft from an energy storage device of an aircraft ground power unit;
- detecting a load to be supported;
- and
- automatically powering the aircraft from a generator of the aircraft ground power unit alternately with the energy storage device based on the detected load.
