Abstract

An example operation includes one or more of reserving an available charging point at a charging station for a vehicle at an arrival time at the charging station when one other charging point at the charging station will be available for one other vehicle in a time less than a threshold time after the arrival time.

Claims (74)

1. A method, comprising:

receiving, via a charging station server, a reservation request from an electric vehicle (EV) which identifies a state of charge (SoC) of a battery in the EV, a desired charge level, and an estimated arrival time of the EV at a charging station;

receiving, via the charging station server, status information from a plurality of bays that are charging a plurality of other EVs:

determining, via the charging station server, a bay from among the plurality of bays that is available for charging the EV at the estimated arrival time based on the reservation request and the status information;

reserving, via the charging station server, the bay at the charging station for the EV at the estimated arrival time at the charging station;

transmitting, via the charging station server, a message to a graphical user interface (GUI) of a display system within the EV with an identifier of the bay:

occupying the bay by the EV;

transferring energy, via a charging point, to the EV at the bay to reach the desired charge level;

stopping, via the charging station server, an ability for the EV to receive energy when one or more of the following occurs:

an amount of time that a number of other EVs waiting to receive the energy at the charging station is greater than a threshold time;

the number of other EVs waiting to receive the energy at the charging station is greater than a threshold number of EVs;

the EV is receiving the energy for a time greater than the other EVs at the charging station; and

the SoC of a-the battery in the EV is greater than a SoC of batteries in the other EVs at the charging station.

2. The method of claim 1 , comprising:

responsive to another bay at the charging station being available, notifying another EV to utilize the another bay at the charging station.

3. The method of claim 1 , wherein the reserving is based on a prediction of at least one other EV arriving at the charging station before the estimated arrival time of the EV at the charging station.

4. The method of claim 1 , comprising:

receiving telemetry data from the EV;

predicting an arrival time of the EV at the charging station based on execution of a machine learning model on the telemetry data; and

reserving the charging station based on the predicted arrival time.

5. The method of claim 1 , comprising:

receiving age attributes of the battery of the EV from the EV; and

reserving the bay at the charging station based on the received age attributes of the battery of the EV.

6. The method of claim 1 , wherein the reserving is based on an average of a time for all other EVs to receive energy at the charging station being equal to or less than the threshold time.

7. A system, comprising:

at least one processor; and

a memory,

wherein the at least one processor and the memory are communicably coupled, and wherein the at least one processor:

receives, via a charging station server, a reservation request from an electric vehicle (EV) which identifies a state of charge (SoC) of a battery in the EV, a desired charge level, and an estimated arrival time of the EV at a charging station;

receives, via the charging station server, status information from a plurality of bays that are charging a plurality of other EVs;

determines a bay from among the plurality of bays that is available for charging the EV at the estimated arrival time based on the reservation request and the status information;

reserves the bay at the charging station for a the EV at the estimated arrival time at the charging station

transmits a message to a graphical user interface (GUI) of a display system within the EV with an identifier of the bay and instructions to occupy the bay by the EV;

transfers energy, via a charging point, to the EV at the bay to reach the desired charge level; and

stops an ability for the EV to receive energy when one or more of the following occurs:

an amount of time that a number of other EVs waiting to receive the energy at the charging station is greater than a threshold time;

the number of other EVs waiting to receive the energy at the charging station is greater than a threshold number of EVs;

the EV receives the energy for a time greater than the other EVs at the charging station; and

the SoC of a-the battery in the EV is greater than a SoC of batteries in the other EVs at the charging station.

8. The system of claim 7 , wherein the at least one processor:

responsive to another bay at the charging station being available, notifies another EV to utilize the another bay at the charging station.

9. The system of claim 7 , wherein the reservation is based on a prediction of at least one other EV arriving at the charging station before the estimated arrival time of the EV at the charging station.

10. The system of claim 7 , wherein the at least one processor:

receives telemetry data from the EV;

predicts an arrival time of the EV at the charging station based on execution of a machine learning model on the telemetry data; and

reserves the charging station based on the predicted arrival time.

11. The system of claim 7 , wherein the at least one processor:

receives age attributes of the battery of the EV from the EV; and

reserve the bay at the charging station based on the received age attributes of the battery of the EV.

12. The system of claim 7 , wherein the reservation is based on an average of a time for all other EVs to receive energy at the charging station being equal to or less than the threshold time.

13. A non-transitory computer readable storage medium comprising instructions, that when read by a processor, cause the processor to perform:

receiving, via a charging station server, a reservation request from an electric vehicle (EV) which identifies a state of charge (SoC) of a battery in the EV, a desired charge level, and an estimated arrival time of the EV at a charging station;

receiving, via the charging station server, status information from a plurality of bays that are charging a plurality of other EVs:

determining a bay from among the plurality of bays that is available for charging the EV at the estimated arrival time based on the reservation request and the status information;

reserving the bay at the charging station for the EV at the estimated arrival time at the charging station;

transmitting a message to a graphical user interface (GUI) of a display system within the EV with an identifier of the bay and instructions to occupy the bay by the EV;

transferring energy, via a charging point, to the EV at the bay to reach the desired charge level; and

stopping an ability for the EV to receive energy when one or more of the following occurs:

an amount of time that a number of other EVs waiting to receive the energy at the charging station is greater than a threshold time;

the number of other EVs waiting to receive the energy at the charging station is greater than a threshold number of EVs;

the EV is receiving the energy for a time greater than the other EVs at the charging station; and

the SoC of a-the battery in the EV is greater than a SoC of batteries in the other EVs at the charging station.

14. The non-transitory computer readable storage medium of claim 13 , wherein the processor performs:

responsive to another bay at the charging station being available, notifying another EV to utilize the another bay at the charging station.

15. The non-transitory computer readable storage medium of claim 13 , wherein the reserving is based on a prediction of at least one other EV arriving at the charging station before the estimated arrival time of the EV at the charging station.

16. The non-transitory computer readable storage medium of claim 13 , wherein the processor performs:

receiving telemetry data from the EV;

predicting an arrival time of the EV at the charging station based on execution of a machine learning model on the telemetry data; and

reserving the charging station based on the predicted arrival time.

17. The non-transitory computer readable storage medium of claim 13 , wherein the processor performs:

receiving age attributes of the battery of the EV from the EV; and

reserving the bay at the charging station based on the received age attributes of the battery of the EV.

18. The non-transitory computer readable storage medium of claim 13 ,

wherein the reserving is based on an average of a time for all other EVs to receive energy at the charging station being equal to or less than the threshold time.
