Abstract

Claims (47)

1 . A method performed by a server, the method comprising:

determining a combined degradation that will occur at a future time for a fixed energy storage (FES) at a location and a mobile energy storage (MES);

determining that one or more of the MES or the FES will be needed based on an emergency need at a certain time;

determining a time to initiate charging of one or more of the MES or the FES based on the combined degradation and the certain time; and

initiating the charging of one or more of the MES or the FES.

2 . The method of claim 1 , comprising:

determining a current charge level of the MES and the FES; and

receiving information regarding an amount of energy received by a third party from at least one of the MES or the FES at the future time.

3 . The method of claim 1 , comprising:

obtaining a temperature forecast for the location during an upcoming time period;

identifying an earliest date in the upcoming time period that a less efficient energy transfer may occur based on the temperature forecast and one or more of an MES location or an FES location; and

providing an energy transfer to the one or more of the MES or the FES before the earliest date.

4 . The method of claim 1 , comprising:

determining an expected performance of one or more of the MES or the FES at the future time;

determining a historical change in peak energy demand at the future time;

determining a difference between the expected performance and the peak energy demand; and

recommending a change to one or more of the MES or the FES to minimize the difference.

5 . A system, comprising:

a processor that, when executing instructions stored in a memory, is configured to:

determine a combined degradation that will occur at a future time for a fixed energy storage (FES) at a location and a mobile energy storage (MES);

determine that one or more of the MES or the FES will be needed based on an emergency need at a certain time;

determine a time to initiate charging of one or more of the MES or the FES based on the combined degradation and the certain time; and

initiate the charging of one or more of the MES or the FES.

6 . The system of claim 5 , wherein the processor is configured to:

determine a current charge level of the MES and the FES; and

receive information regarding an amount of energy received by a third party from at least one of the MES or the FES at the future time.

7 . The system of claim 5 , wherein the processor is configured to:

obtain a temperature forecast for the location for a future time period;

identify an earliest date in the upcoming time period that a less efficient energy transfer may occur based on the temperature forecast and one or more of an MES location or an FES location; and

provide an energy transfer to the one or more of the MES or the FES before the earliest date.

8 . The system of claim 5 , wherein the processor is configured to:

determine an expected performance of one or more of the MES or the FES at the future time;

determine a historical change in peak energy demand to the future time;

determine a difference between the expected performance and the peak energy demand; and

recommend a change to one or more of the MES or the FES to minimize the difference.

9 . A computer-readable storage medium comprising instructions that, when executed by a processor, cause the processor to perform:

determining a combined degradation that will occur at a future time for a fixed energy storage (FES) at a location and a mobile energy storage (MES);

determining that one or more of the MES or the FES will be needed based on an emergency need at a certain time;

determining a time to initiate charging of one or more of the MES or the FES based on the combined degradation and the certain time; and

initiating the charging of one or more of the MES or the FES.

10 . The computer-readable storage medium of claim 9 , wherein the instructions cause the processor to perform:

determining a current charge level of the MES and the FES; and

receiving information regarding an amount of energy received by a third party from at least one of the MES or the FES at the future time.

11 . The computer-readable storage medium of claim 9 , wherein the instructions cause the processor to perform:

obtaining a temperature forecast for the location during an upcoming time period;

identifying an earliest date in the upcoming time period that a less efficient energy transfer may occur based on the temperature forecast and one or more of an MES location or an FES location; and

providing an energy transfer to the one or more of the MES or the FES before the earliest date.
