Abstract

A fleet management system dispatches autonomous electric vehicles (AEVs) as on-demand power sources. The fleet management system receives a request for a power source including a location and data describing the amount of power requested. The fleet management system selects an AEV of the fleet to service the request based on the relative locations of the AEVs to the requested location, and based on the amount of power requested. The fleet management system instructs the selected AEV to drive to the location and supply power. The fleet management system instructs the selected AEV to disconnect and return to the charging station, and may instruct another AEV to continue fulfilling the request if additional power is needed.

First claim

What is claimed is:

1. A method for dispatching a power source comprising:
receiving a request for a power source, the request comprising a location and timing data;
determining an estimated amount of energy for servicing the request based at least in part on the timing data and data describing energy usage at the location;
selecting an autonomous electric vehicle (AEV) from a fleet of AEVs to fulfill the request, the AEV selected based on a current location of the AEV, the location, a battery level of a battery of the AEV, and the estimated amount of energy for servicing the request;
instructing the AEV to drive to the location, wherein the AEV is configured to distribute electric power from the battery upon reaching the location;
receiving, from the AEV, an updated battery level of the battery; and
calculating an estimated duration for which the AEV can service the request, the estimated duration calculated based on the updated battery level, a distribution rate of the battery, and an estimated amount of energy for the AEV to return to a charging station.

2. The method of claim 1 , further comprising:
determining that an estimated time for servicing the request exceeds the estimated duration for which the AEV can service the request;
selecting a second AEV from the fleet of AEVs to fulfill the request;
determining, based on the estimated duration, a cutoff time until which the AEV can distribute electric power in service of the request; and
instructing the second AEV to drive to the location such that the second AEV reaches the location before the cutoff time.

3. The method of claim 1 , wherein determining the estimated amount of energy for servicing the request comprises:
determining an estimated energy consumption rate for the request, the estimated energy consumption rate based on at least one of usage data received from a user and historical energy consumption data from a prior request;
determining, based on the timing data, an estimated duration for the request, the timing data received from at least one of a user and a utility company; and
calculating the estimated amount of energy based on the estimated energy consumption rate and the estimated duration.

4. The method of claim 3 , further comprising:
determining an actual energy consumption rate for the request based on a rate at which the AEV distributes electric power from the battery at the location;
comparing the actual energy consumption rate to the estimated energy consumption rate; and
in response to determining that the actual energy consumption rate is higher than the estimated energy consumption rate, transmitting an alert to a user device.

5. The method of claim 1 , wherein the request for a power source is submitted by a user, and the location, timing data, and data describing energy usage at the location are input by the user through a user interface of a user device and transmitted from the user device to a fleet management system.

6. The method of claim 1 , wherein the request for a power source is a request submitted by a user to receive backup power during a power outage, the method further comprising:
receiving, from at least one of a utility company and a monitoring device at the location, an alert that the location has a power outage;
receiving, from the utility company, an estimated duration of the power outage; and
determining the estimated amount of energy for servicing the request further based on the estimated duration.

7. The method of claim 1 , wherein the request for a power source is received from a utility company in response to the utility company determining that it cannot meet demand from at least one customer location, and the AEV distributes power to the at least one customer location.

8. A fleet management system comprising:
a user interface (UI) server configured to receive a request for a power source at a location;
a power source manager configured to:
determine an estimated amount of energy for servicing the request based at least in part on a duration associated with the request and data describing energy usage at the location; and
select an autonomous electric vehicle (AEV) from a fleet of AEVs to fulfill the request, the AEV selected based on a current location of the AEV, the location, a battery level of a battery of the AEV, and the estimated amount of energy for servicing the request; and

a vehicle manager configured to instruct the AEV to drive to the location, wherein the AEV is configured to distribute electric power from the battery upon reaching the location;
wherein the power source manager is further configured to:
receive, from the AEV, an updated battery level of the battery after the AEV has begun distributing electric power from the battery; and
calculate an estimated duration for which the AEV can service the request, the estimated duration calculated based on the updated battery level, a distribution rate of the battery, and an estimated amount of energy for the AEV to return to a charging station.

9. The system of claim 8 , wherein the power source manager is further configured to:
determine that an estimated time for servicing the request exceeds the estimated duration for which the AEV can service the request;
select a second AEV from the fleet of AEVs to fulfill the request;
determine, based on the estimated duration, a cutoff time until which the AEV can distribute electric power in service of the request; and
instruct the second AEV to drive to the location such that the second AEV reaches the location before the cutoff time.

10. The system of claim 8 , wherein the power source manager is configured to determine the estimated amount of energy for servicing the request by:
determining an estimated energy consumption rate for the request, the estimated energy consumption rate based on at least one of usage data received from a user and historical energy consumption data from a prior request; and
calculating the estimated amount of energy based on the estimated energy consumption rate and the duration associated with the request, the duration received from at least one of a user and a utility company.

11. The system of claim 10 , wherein the power source manager is further configured to:
determine an actual energy consumption rate for the request based on a rate at which the AEV distributes electric power from the battery at the location;
compare the actual energy consumption rate to the estimated energy consumption rate; and
in response to a determination that the actual energy consumption rate is higher than the estimated energy consumption rate, transmit an alert to a user device.

12. The system of claim 8 , wherein the request for a power source is submitted by a user, and the location, duration, and data describing energy usage at the location are input by the user through a user interface of a user device and transmitted from the user device to the fleet management system.

13. The system of claim 8 , wherein the request for a power source is a request submitted by a user to receive backup power during a power outage, and the power source manager is further configured to:
receive, from at least one of a utility company and a monitoring device at the location, an alert that the location has a power outage;
receive, from the utility company, an estimated duration of the power outage; and associate the estimated duration with the request.

14. The system of claim 8 , wherein the request for a power source is received from a utility company in response to the utility company determining that it cannot meet demand from at least one customer location, and the AEV
