Airport electric vehicle charging system
In an embodiment, an airport electric vehicle charging system includes a current transducer electrically coupled with a power source; a solid state converter electrically coupleable with an aircraft at or near an airport gate and configured to provide and maintain power to the aircraft; and a controller. The system further includes a first feedback loop between the controller and the current transducer; a second feedback loop between the controller and the solid state converter; and a battery charger electrically coupled with the power source and configured to charge one or more electric vehicles. The first feedback loop provides a first feedback signal generated by the current transducer to the controller. The second feedback loop provides a second feedback signal generated by the solid state converter to the controller. The battery charger is configured to consume power from the power source in accordance with the first and second feedback signals.
1. An airport electric vehicle charging system comprising:
a current transducer electrically coupled with a power source;
a solid state converter electrically coupleable with an aircraft at or near an airport gate and configured to provide and maintain power, from the power source, to the aircraft at a power level requested by the aircraft;
a controller;
a first feedback loop between the controller and the current transducer, wherein the first feedback loop provides a first feedback signal generated by the current transducer to the controller;
a second feedback loop between the controller and the solid state converter, wherein the second feedback loop provides a second feedback signal generated by the solid state converter to the controller;
a battery charger electrically coupled with the power source and configured to charge one or more electric vehicles, wherein the battery charger is configured to consume power from the power source in accordance with the first and second feedback signals; and
a battery bank comprising one or more batteries electrically coupled with the battery charger, wherein the battery bank is configured for receiving power from the battery charger through a local battery charging line, and wherein the battery bank is configured for charging a ground support equipment (GSE).
2. The system of claim 1 , wherein the controller is configured to determine a maximum available excess power value based on the first and second feedback signals and generate a control signal indicative of the determined maximum available excess power value.
3. The system of claim 2 , wherein the battery charger receives the control signal and consumes power from the power source up to the maximum available excess power value indicated in the control signal.
4. The system of claim 1 , wherein the current transducer is configured to monitor an amount of power being consumed by the system and generate the first feedback signal indicative of the amount of power being consumed by the system.
5. The system of claim 1 , wherein the solid state converter is configured to monitor an amount of power being consumed by the aircraft and generate the second feedback signal indicative of the amount of power being consumed by the aircraft.
6. The system of claim 1 , further comprising a central monitoring unit in communication with the controller, wherein the central monitoring unit receives first power consumption data associated with the system and second power consumption data associated with a second system, different from the system, located at or near a second gate of the airport.
7. The system of claim 1 , wherein an electrical connection between the system and the power source is located at the airport gate, an airport gate rotunda, an airport rotunda, or airport building.
8. The system of claim 1 , wherein the solid state converter is configured to provide aircraft-compatible power or 400 Hertz (Hz) power to the aircraft.
9. An airport electric vehicle charging system comprising:
a current transducer directly electrically coupled with a power source;
a solid state converter electrically coupleable with an aircraft at or near an airport gate and configured to provide and maintain power, from the power source, to the aircraft at a power level requested by the aircraft;
a controller outside of a direct electrical path from the power source to the current transducer;
a battery charger electrically coupled with the power source and configured to charge one or more electric vehicles; and
a battery bank comprising one or more batteries electrically coupled with the battery charger, wherein the battery bank is configured for receiving power from the battery charger through a local battery charging line, and wherein the battery bank is configured for charging a ground support equipment (GSE).
10. The system of claim 9 , wherein the solid state converter is configured to consume power from the power source based on:
a first feedback loop between the controller and the current transducer, wherein the first feedback loop provides a first feedback signal generated by the current transducer to the controller; and
a second feedback loop between the controller and the solid state converter, wherein the second feedback loop provides a second feedback signal generated by the solid state converter to the controller.
