Abstract

The technology relates to managing power of an aerial vehicle. The system may include an aerial vehicle having a power storage module and one or more components, as well as a computing device communicatively coupled to the aerial vehicle. The computing device may include a processor and a memory storing instructions which, when executed by the processor, may cause the computing device to receive data indicating a state of charge of the power storage module, receive data indicating a rate of power consumption of the at least one component, generate a power command based on at least one of the state of charge of the power storage module or the rate of power consumption of the at least one component, and transmit the power command to the aerial vehicle.

Claims (40)

1. A system for managing power of an aerial vehicle, the system comprising:

an aerial vehicle including:

a power storage module, and

at least one component;

a computing device communicatively coupled to the aerial vehicle, the computing device including a processor and a memory storing instructions which, when executed by the processor, cause the computing device to:

receive data indicating a state of charge of the power storage module,

receive data indicating a rate of power consumption of the at least one component,

determine an expected amount of power required to provide power to the at least one component for a predetermined amount of time,

generate a power command based on the expected amount of power needed to provide power to the at least one component for the predetermined amount of time and one or both of the state of charge of the power storage module or the rate of power consumption of the at least one component, and

transmit the power command to the aerial vehicle.

2. The system according to claim 1 , wherein the power command causes the aerial vehicle to switch from a first operating mode to a second operating mode.

3. The system according to claim 2 , wherein the at least one component includes at least one flight-related component and at least one non-flight related component, and wherein the first operating mode allows power to be provided to the at least one flight-related component and the at least one non-flight related component.

4. The system according to claim 2 , wherein the second operating mode is a power-saving operating mode.

5. The system according to claim 4 , wherein the power-saving operating mode allows power to be provided to the at least one flight-related component and prevents power from being provided to the at least one non-flight related component.

6. The system according to claim 4 , wherein the aerial vehicle further includes at least one heater, and wherein the power-saving operating mode allows power to be provided to the at least one heater.

7. The system according to claim 4 , wherein the power-saving operating mode causes the at least one non-flight related component to switch to a power-saving state.

8. The system according to claim 7 , wherein the power-saving state allows the at least one non-flight related component to only consume power to stay warm.

9. The system according to claim 2 , wherein the second operating mode is a low-power operating mode.

10. The system according to claim 9 , wherein the at least one component includes at least one flight-related component and at least one non-flight related component, and wherein the low-power operating mode causes the at least one non-flight related component to switch to a power-off state.

11. The system according to claim 9 , wherein the low-power operating mode causes the aerial vehicle to initiate a descent process.

12. The system according to claim 1 , wherein the instructions, when executed by the processor, further cause the computing device to determine whether the state of charge of the power storage module is greater than a threshold.

13. The system according to claim 1 , wherein the instructions, when executed by the processor, further cause the computing device to determine whether the rate of power consumption is greater than a threshold.

14. The system according to claim 1 , wherein the instructions, when executed by the processor, further cause the computing device to:

receive data indicating a location of the aerial vehicle; and

determine a time until sunrise based on the location of the aerial vehicle.

15. The system according to claim 14 , wherein the instructions, when executed by the processor, further cause the computing device to determine an expected amount of power required to provide power to the at least one component until sunrise.

16. The system according to claim 15 , wherein the generation of the power command is further based on the determined expected amount of power needed to provide power to the at least one component until sunrise.

17. The system according to claim 1 , wherein the aerial vehicle includes a balloon.

18. A method for managing power of an aerial vehicle, the method comprising:

receiving data indicating a state of charge of a power storage module coupled to the aerial vehicle;

receiving data indicating a rate of power consumption of at least one component coupled to the aerial vehicle;

determining an expected amount of power required to provide power to the at least one component for a predetermined amount of time;

generating a power command based on the expected amount of power needed to provide power to the at least one component for the predetermined amount of time and one or both of the state of charge of the power storage module or the rate of power consumption of the at least one component; and

transmitting the power command to the aerial vehicle.

19. A non-transitory computer-readable storage medium storing instructions which, when executed by a processor, cause a computing device to:

receive data indicating a state of charge of a power storage module coupled to an aerial vehicle;

receive data indicating a rate of power consumption of at least one component coupled to the aerial vehicle;

determine an expected amount of power required to provide power to the at least one component for a predetermined amount of time;

generate a power command based on the expected amount of power needed to provide power to the at least one component for the predetermined amount of time and one or both of the state of charge of the power storage module or the rate of power consumption of the at least one component; and

transmit the power command to the aerial vehicle.
