Abstract

A method for recharging an electric vehicle includes receiving, by a control module and from the vehicle in transit along a route having a number of stops for passenger pickup, a current charge level and a current location. The stops include recharging stations for recharging the vehicle. The method includes receiving from a next stop, an anticipated stop time at the next stop for the vehicle. The method includes determining a power output to be supplied to the vehicle by a recharging station at the next stop based on the current charge level. The power output comprises an amount of power to be supplied at the next stop, the amount of power for satisfying a minimum amount of charge to enable the vehicle to arrive at a subsequent stop after the next stop. The method includes transmitting, to the recharging station at the next stop, the power output.

Claims

1. A method for recharging an electric vehicle, the method comprising:

receiving, by a control module and from a vehicle in transit along a route having a number of stops for passenger pickup, a current charge level and a current location, wherein the number of stops include recharging stations configured to recharge the vehicle;

receiving, by the control module, an anticipated stop time at the next stop for the vehicle wherein the anticipated stop time is derived from a number of passengers unloading from and loading onto on the vehicle at the next stop;

determining, by the control module, a power amount to be supplied to the vehicle by a recharging station of the recharging stations at the next stop based on the current charge level and the anticipated stop time, wherein the power amount includes at least an amount of charge to enable the vehicle to arrive at a subsequent stop of the number of stops after the next stop;

configuring, by the control module, the recharging station at the next stop to provide the power amount to the vehicle in a duration that is based on the anticipated passenger stop time.

2. The method of claim 1, wherein the power amount is derived from an environmental condition affecting the vehicle between the next stop and the subsequent stop, the environmental condition comprising at least one of traffic, geographical terrain, and weather.

3. The method of claim 1, further comprising receiving, by the control module and from the vehicle in transit along the route, a charge capacity for the vehicle, wherein the power amount is determined based on the charge capacity.

4. An apparatus for recharging an electric vehicle, the apparatus comprising:

a processor; and

a control module executable on the processor, the control module configured to,

receive, from a vehicle in transit along a route having a number of stops for passenger pickup, a current charge level and a current location, wherein the number of stops include recharging stations configured to recharge the vehicle;

receive an anticipated stop time at the next stop for the vehicle, wherein the anticipated stop time is derived from a number of passengers unloading from and loading onto the vehicle at the next stop;

determine a power amount to be supplied to the vehicle by a recharging station of the recharging stations at the next stop based on the current charge level and the anticipated stop time, wherein the power amount comprises an amount of power to satisfy a minimum amount of charge to enable the vehicle to arrive at a subsequent stop of the number of stops after the next stop; and

configure the recharging station at the next stop to provide the power amount to the vehicle in a duration that is based on the anticipated passenger stop time.

5. The apparatus of claim 4, wherein the power amount is derived from an environmental condition affecting the vehicle between the next stop and the subsequent stop, the environmental condition comprising at least one of traffic, geographical terrain, and weather.

6. The apparatus of claim 4, wherein the control module is configured to receive, from the vehicle, a charge capacity for the vehicle, wherein the power amount is determined based on the charge capacity.

7. A computer program product for recharging an electric vehicle, the computer program product comprising:

a non-transitory computer readable storage medium having computer usable program code embodied therewith, the computer usable program code comprising computer usable program code including;

code to receive, from a vehicle in transit along a route having a number of stops for passenger pickup, a current charge level and a current location, wherein the number of stops include recharging stations configured to recharge the vehicle;

code to receive, from a next stop of the number of stops, an anticipated stop time at the next stop for the vehicle, wherein the anticipated stop time is derived from a number of passengers unloading from and loading onto the vehicle at the next stop;

code to determine a power amount to be supplied to the vehicle by a recharging station of the recharging stations at the next stop based on the current charge level and the anticipated stop time, wherein the power amount comprises an amount of power needed to enable the vehicle to arrive at a subsequent stop of the number of stops after the next stop; and

code to configure, by the control module, the recharging station at the next stop to provide the power amount to the vehicle in a duration that is based on the anticipated passenger stop time.

8. The computer program product of claim 7, wherein the power amount is derived from an environmental condition affecting the vehicle between the next stop and the subsequent stop, the environmental condition comprising at least one of traffic, geographical terrain, and weather.

9. The computer program product of claim 7 further comprising code to receive, from the vehicle, a charge capacity for the vehicle, wherein the power amount is determined based on the charge capacity.
