Abstract

Systems and methods are disclosed for energy control and vehicle energy control. A vehicle energy control system includes an intelligent device that is configured to determine an energy demand of the intelligent device during an operation of a vehicle. The vehicle energy control system also includes an energy management system. The energy management system is configured to communicate with the intelligent device regarding the energy demand to coordinate scheduling of energy distribution during the operation. The energy management system is further configured to generate an energy distribution schedule to account for the energy demand and at least a second energy demand of another device.

Claims

1. A vehicle energy control system, comprising:

an intelligent device that is configured to determine an energy demand of the intelligent device during an operation of a vehicle; and

an energy management system configured to;

communicate with the intelligent device regarding the energy demand to coordinate scheduling of energy distribution during the operation; and

generate an energy distribution schedule to account for the energy demand and at least a second energy demand of another device.

2. The vehicle energy control system of claim 1, further comprising a supply configured to support distribution of the energy demand.

3. The vehicle energy control system of claim 1, wherein the energy management system is configured to control distribution of energy within the vehicle based on the energy demand and the second energy demand according to the energy distribution schedule.

4. The vehicle energy control system of claim 1, wherein at least one of the energy demand and the second energy demand includes an expected electrical demand during the one or more phases of the operation.

5. The vehicle energy control system of claim 1, wherein the energy distribution schedule allocates distribution of energy responsive to the energy demand and the second energy demand for one or more periods during the operation.

6. The vehicle energy control system of claim 1, wherein the intelligent device is further configured to change the energy demand in response to a command from the energy management system.

7. The vehicle energy control system of claim 6, wherein the at least one intelligent device is configured to change the energy demand by one of:

reducing the energy demand;

assuming a standby state from which the at least one intelligent device can resume operation upon being restarted by the energy management system; and

powering off.

8. The vehicle energy control system of claim 1, wherein the at least one intelligent device is further configured to reschedule a timing of the energy demand in response to a command from the energy management system.

9. The vehicle energy control system of claim 1, further comprising a controller disposed within the intelligent device, the controller configured to determine the energy demand of the intelligent device for one or more periods during a journey of the vehicle and to notify the energy management system of the energy demand for each of the one or more periods.

10. The vehicle energy control system of claim 9, wherein the energy management system is configured to automatically establish the communication with the at least one intelligent device.

11. A system, comprising:

a distribution system configured to receive energy from one or more energy sources aboard a vehicle and to transfer the received energy to one or more energy receiving devices;

an energy management system configured to;

communicate with one or more of the one or more energy sources to determine a quantity of energy available from the one or more energy sources; and

schedule distribution of the energy available to the one or more energy receiving devices.

12. The system of claim 11, wherein the one or more energy sources include a non-generator-based energy source including one or more of:

13. The system of claim 11, wherein a first energy source of the one or more energy sources includes a controller operable, in response to an instruction from the energy management system, to change at least one of a first quantity of energy available from the first energy source and a time at which the first quantity of energy available from the first energy source is received.

14. The system of claim 11, wherein a first energy receiving device of the one or more energy receiving devices includes a controller operable, in response to an instruction from the energy management system, to change at least one of the first quantity of energy to be transferred to the first energy receiving device and a time at which the first quantity of energy is distributed to the first energy receiving device.

15. The system of claim 11, wherein the energy management system communicates with the one or more energy sources and the one or more energy receiving devices via a data bus.

16. A method, comprising:

communicating with one or more intelligent devices to coordinate scheduling for energy distribution during one or more phases of operation of a vehicle, wherein the one or more intelligent devices are configured to report, for one or more phases of the operation of the vehicle, a quantity of energy available to be provided or an energy demand;

determining a total energy available to be distributed and a total energy demand for each of the one or more phases;

determining a schedule for energy distribution based on the total energy available to be distributed and the total energy demand for each of the one or more phases.

17. The method of claim 16, further comprising distributing the total energy available among the one or more energy receiving devices according to the schedule.
