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.

First claim

What is claimed is:

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.
