Efficient power transfer to electric vehicles
An ability of a power transmission device to transfer electric charge in a power-transmission area at a particular point in time is identified. The ability comprises a threshold number of vehicles to which the power-transmission device can transfer electric charge with at least a threshold efficiency. A predicted number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time is calculated. The number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time is adjusted based on a determination that the predicted number of vehicles is not bound by the threshold number of vehicles.
1 . A method comprising:
identifying an ability of a power-transmission device to transfer electric charge in a power-transmission area at a particular point in time, wherein the ability comprises a threshold number of vehicles to which the power-transmission device can transfer electric charge with at least a threshold efficiency;
calculating a predicted number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time;
determining that the predicted number of vehicles is not bound by the threshold number of vehicles; and
adjusting, by deactivating the power-transmission device and based on the determining, the number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time.
2 . The method of claim 1 , wherein the adjusting comprises:
selecting an electric vehicle; and
issuing rerouting information to the electric vehicle, wherein the rerouting information contains a changed route that, when followed by the electric vehicle, changes the number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time.
3 . The method of claim 2 , wherein the selected electric vehicle is in the predicted number of electric vehicles and wherein the changed route would cause the electric vehicle to be not present in the power-transmission area at the particular point in time.
4 . The method of claim 2 , wherein the selected electric vehicle is not in the predicted number of electric vehicles and wherein the changed route would cause the electric vehicle to be present in the power-transmission area at the particular point in time.
5 . The method of claim 2 , wherein the selecting comprises:
identifying a consequence of the changed route;
comparing the consequence of the changed route to a profile for the electric vehicle; and
determining, based on the comparing, that the consequence does not violate a restriction in the profile.
6 . The method of claim 5 , wherein the consequence of the changed route comprises a predicted remaining charge of the electric vehicle after following the changed route.
7 . The method of claim 5 , wherein the consequence of the changed route comprises a time of completion of the changed route.
8 . The method of claim 5 , wherein the consequence of the changed route comprises a number of reroute instructions issued to the electric vehicles over a period of time.
9 . The method of claim 1 , wherein the adjusting comprises changing a speed limit in the power-transmission area.
10 . The method of claim 1 , wherein the adjusting comprises a cost of electric charge in the power-transmission area.
11 . The method of claim 1 , wherein the adjusting comprises changing a direction of a lane in the power-transmission area.
12 . The method of claim 1 , wherein the calculating comprises:
identifying a set of road properties during the particular point in time;
identifying a set of historical road properties that matches the set of road properties; and
identifying a historical number of electric vehicles that requested electric charge during a historical point in time that corresponds to the historical road properties.
13 . A system comprising:
a processor; and
a memory in communication with the processor, the memory containing program instructions that, when executed by the processor, are configured to cause the processor to perform a method, the method comprising:
identifying an ability of a power-transmission device to transfer electric charge in a power-transmission area at a particular point in time, wherein the ability comprises a threshold number of vehicles to which the power-transmission device can transfer electric charge with at least a threshold efficiency;
calculating a predicted number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time;
determining that the predicted number of vehicles is not bound by the threshold number of vehicles; and
adjusting, by deactivating the power-transmission device and based on the determining, the number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time.
14 . The system of claim 13 , wherein the adjusting comprises:
selecting an electric vehicle; and
issuing rerouting information to the electric vehicle, wherein the rerouting information contains a changed route that, if followed by the electric vehicle, would change the number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time.
15 . The system of claim 13 , wherein the adjusting comprises a cost of electric charge in the power-transmission area.
16 . The system of claim 14 , wherein the calculating comprises:
identifying a set of road properties during the particular point in time;
identifying a set of historical road properties that matches the set of road properties; and
identifying a historical number of electric vehicles that requested electric charge during a historical point in time that corresponds to the historical road properties.
17 . 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 computer to cause the computer to:
identify an ability of a power-transmission device to transfer electric charge in a power-transmission area at a particular point in time, wherein the ability comprises a threshold number of vehicles to which the power-transmission device can transfer electric charge with at least a threshold efficiency;
calculate a predicted number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time;
determine that the predicted number of vehicles is not bound by the threshold number of vehicles; and
adjust, by deactivating the power-transmission device and based on the determining, the number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time.
18 . The computer program product of claim 17 , wherein the program instructions are further executable by the computer to cause the computer to:
select an electric vehicle; and
issue rerouting information to the electric vehicle, wherein the rerouting information contains a changed route that, if followed by the electric vehicle, would change the number of electric vehicles that are likely to be requesting electric charge within the power-transmission area at the particular point in time.
19 . The computer program product of claim 17 , wherein the adjusting comprises changing a direction of a lane in the power-transmission area.
20 . The computer program product of claim 17 , wherein the calculating comprises:
identifying a set of road properties during the particular point in time;
