Abstract

Methods, systems, and computer program products for managing a picogrid with a computing device are provided herein. A method includes generating one or more power-related models based on (i) data pertaining to a given device battery, (ii) data pertaining to one or more context sources, and (iii) one or more items of power-related historical data; determining a charging schedule for the given device battery to provision power for a picogrid based on the one or more power-related models, wherein said picogrid comprises a set of one or more additional devices connected to (i) the given device and (ii) an energy storage component; and implementing the charging schedule on the given device.

First claim

What is claimed is:

1. A method comprising:
generating one or more power-related models based on (i) data pertaining to a battery of a given device, (ii) data pertaining to one or more context sources, and (iii) one or more items of power-related historical data, wherein said one or more items of power-related historical data comprise an energy price schedule, and wherein said one or more context sources comprise user preferences comprising (a) a scheduled time for beginning use of the battery of the given device, (b) an average state of charge of the battery of the given device at the scheduled time for beginning use, and (c) an average duration of time for use of the battery of the given device;
determining a charging schedule for the battery of the given device to provision power for a picogrid based on the one or more power-related models, wherein the battery of the given device comprises a battery of a portable computing device with sufficient storage capacity to power said picogrid, and wherein said picogrid comprises a set of one or more additional devices connected to (i) the given device and (ii) an energy storage component; and
implementing the charging schedule on the given device;
wherein said generating, said determining, and said implementing are carried out by at least one computing device.

2. The method of claim 1 , wherein the battery of the given device comprises a laptop battery.

3. The method of claim 1 , wherein said data pertaining to the given device battery comprise data related to a charge rate of the battery of the given device.

4. The method of claim 1 , wherein said data pertaining to the battery of the given device comprise data related to a discharge rate of the battery of the given device.

5. The method of claim 1 , wherein said data pertaining to the battery of the given device comprise a capacity of the battery of the given device.

6. The method of claim 1 , wherein said one or more context sources comprise one or more user-related constraints.

7. The method of claim 1 , wherein said user preferences comprise a lower bound on time before a complete discharge of the battery of the given device.

8. The method of claim 1 , wherein said user preferences comprise a scheduled time for ending use of the battery of the given device.

9. The method of claim 1 , wherein said one or more context sources comprise one or more battery-related constraints.

10. The method of claim 1 , wherein said one or more items of power-related historical data comprise one or more historical power cut schedules.

11. A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computing device to cause the computing device to:
generate one or more power-related models based on (i) data pertaining to a battery of a given device, (ii) data pertaining to one or more context sources, and (iii) one or more items of power-related historical data, wherein said one or more items of power-related historical data comprise an energy price schedule, and wherein said one or more context sources comprise user preferences comprising (a) a scheduled time for beginning use of the battery of the given device, (b) an average state of charge of the battery of the given device at the scheduled time for beginning use, and (c) an average duration of time for use of the battery of the given device;
determine a charging schedule for the battery of the given device to provision power for a picogrid based on the one or more power-related models, wherein the battery of the given device comprises a battery of a portable computing device with sufficient storage capacity to power said picogrid, and wherein said picogrid comprises a set of one or more additional devices connected to (i) the given device and (ii) an energy storage component; and
implement the charging schedule on the given device.

12. A system comprising:
a memory; and
at least one processor coupled to the memory and configured for:
generating one or more power-related models based on (i) data pertaining to a battery of a given device, (ii) data pertaining to one or more context sources, and (iii) one or more items of power-related historical data, wherein said one or more items of power-related historical data comprise an energy price schedule, and wherein said one or more context sources comprise user preferences comprising (a) a scheduled time for beginning use of the battery of the given device, (b) an average state of charge of the battery of the given device at the scheduled time for beginning use, and (c) an average duration of time for use of the battery of the given device;
determining a charging schedule for the battery of the given device to provision power for a picogrid based on the one or more power-related models, wherein the battery of the given device comprises a battery of a portable computing device with sufficient storage capacity to power said picogrid, and wherein said picogrid comprises a set of one or more additional devices connected to (i) the given device and (ii) an energy storage component; and
implementing the charging schedule on the given device.

13. The method of claim 1 , comprising:
updating the charging schedule in response to one or more changed parameters.

14. The method of claim 13 , wherein said one or more changed parameters comprise at least one of a modeling error, user deviation from the charging schedule, a change in a projected energy price schedule, and passage of a pre-determined amount of time.

15. The method of claim 13 , wherein said updating is based on solving an optimization problem to minimize a projected cost of power consumed by the picogrid over a given period of time, subject to at least one of (i) one or more battery-related constraints and (ii) one or more user-related constraints.
