Abstract

Techniques for electric vehicle systems, and in particular to electric vehicle charging systems and associated methods of use are provided. In one embodiment, a system for aligning a charging panel of an electrical vehicle to receive a charge from an external source is provided, the system comprising a charging panel interconnected to the electrical vehicle; an actuator interconnected to the charging panel; a sensor configured to sense an alignment measurement between the charging panel and an external power source; and an alignment controller that receives the alignment measurement and determines a required alignment adjustment, wherein the charging panel may be adjusted to receive the charge from the external power source.

Claims

1. A system for aligning a charging panel of an electrical vehicle with an external power source embedded in a roadway surface, the system comprising:

a charging panel interconnected to the electrical vehicle;

an actuator interconnected to the charging panel;

a sensor configured to sense an alignment measurement between the charging panel and the external power source; and

an alignment controller that receives the alignment measurement and determines a required alignment adjustment, wherein the charging panel is configured to be adjusted in alignment with the external power source, and wherein a separation distance between the charging panel relative to the external power source is based on a roadway type and is selected from a vehicle database, the vehicle database including a plurality of separation distances and a plurality of roadway types.

2. The system of claim 1, wherein the sensor is disposed on the electrical vehicle.

3. The system of claim 1, wherein the sensor is disposed external to the electrical vehicle.

4. The system of claim 1, wherein the required alignment adjustment is presented to a user of the electrical vehicle on a graphical user interface.

5. The system of claim 4, wherein the graphical user interface is disposed on a mobile device.

6. The system of claim 1, wherein the alignment controller provides signals to the actuator to adjust the charging panel in three different translation positions.

7. The system of claim 6, wherein the alignment controller provides signals to the actuator to adjust the charging panel in different angular positions.

8. The system of claim 1, further comprising an armature interconnected to the charging panel and the actuator, wherein the actuator moves the armature to effect the required alignment adjustment.

9. The system of claim 8, wherein the alignment measurement is a horizontal distance measurement and the required alignment adjustment is a horizontal displacement of the charging panel.

10. The system of claim 9, wherein the required alignment adjustment is automatically adjusted by the alignment controller by way of the actuator.

11. The system of claim 10, wherein charge is provided from the external power source embedded in the roadway while the electrical vehicle is moving relative to the roadway surface.

12. A method for aligning a charging panel of an electrical vehicle with an external power source embedded in a roadway, the method comprising:

positioning, by a microprocessor, a charging panel relative to the external power source, the charging panel interconnected to the electrical vehicle, and the charging panel positioned by an actuator;

measuring, by a sensor, an alignment measurement between the charging panel and the external power source, wherein a separation distance between the charging panel relative to the external power source is based on a roadway type and is selected from a vehicle database, the vehicle database including a plurality of separation distances and a plurality of roadway types;

transmitting, by the microprocessor, the alignment measurement to an alignment controller;

receiving, by the alignment controller, the alignment measurement;

determining, by the microprocessor, a required alignment adjustment; and

adjusting, by the microprocessor, a position of the charging panel in accordance with the required alignment adjustment and the separation distance selected from the vehicle database.

13. The method of claim 12, further comprising an armature interconnected to the charging panel and the actuator, wherein the actuator maneuvers the armature to effect the required alignment adjustment.

14. The method of claim 12, wherein the sensor is disposed on the electrical vehicle.

15. The method of claim 12, wherein adjusting the position of the charging panel includes adjusting at least one of a translation position and an angular position of the charging panel.

16. The method of claim 12, wherein the sensor is disposed external to the electrical vehicle.

17. The method of claim 12, wherein the alignment measurement is a horizontal distance measurement and the required alignment adjustment is a horizontal displacement of the charging panel.

18. The method of claim 17, wherein the required alignment adjustment is automatically adjusted by the alignment controller by way of the actuator.

19. The method of claim 12, wherein the required alignment adjustment is presented to a user of the electrical vehicle on a graphical user interface.

20. The method of claim 19, wherein the graphical user interface is disposed on a mobile device.
