EV charging connector unlock via biometric input

1. A charging system for an electric vehicle, comprising:

a receptacle on the electric vehicle; and

a controller configured to,

responsive to a removal request and a discrepancy between a stored biometric record and first biometric data received from a first biometric sensor, compare the stored biometric record and second biometric data received from a second biometric sensor that is different from the first biometric sensor,

responsive to the comparison matching, generate an unlock request, and

responsive to the comparison not matching and an override command received from a user interface disposed within the electric vehicle, generate an unlock request.

2. The charge system of claim 1 , wherein the stored biometric record includes data recorded from the first and second biometric sensors when a charge plug is coupled with the receptacle.

3. The charge system of claim 2 , wherein the first biometric sensor is a fingerprint reader or a palmprint reader.

4. The charge system of claim 3 , wherein the first biometric sensor is integrated with a switch.

5. The charge system of claim 3 , wherein the second biometric sensor is a fingerprint reader, palmprint reader, microphone, or camera.

6. The charge system of claim 5 , wherein the second biometric sensor is mounted on an outer surface of the electric vehicle in vicinity of the receptacle, on a door of the electric vehicle in vicinity of a door handle on the door, or on the outer surface of the electric vehicle in vicinity of the door handle.

7. The charge system of claim 2 , wherein the biometric record comprises at least one of a thumbprint, a fingerprint, a palmprint, a retinal image, a facial image, a voice signature, and a voice signature of a code word.

8. A method of unlocking an electric vehicle plug comprising:

by a controller,

responsive to a disconnection request, comparing biometric data received from a first biometric sensor and a stored biometric record,

responsive to a discrepancy in the comparison, comparing second biometric data, received from a second biometric sensor that is different from the first biometric sensor, with the stored biometric record,

responsive to the second biometric data comparison matching, unlocking the electric vehicle plug, and

responsive to the second biometric data comparison not matching and an override command received from a remote server, unlocking the electric chicle plug.

9. The method of claim 8 further comprising, responsive to a charge request, activating the first biometric sensor, storing data as an entry in the stored biometric data, and releasing a locking mechanism such that the plug may be decoupled from an electric vehicle charge station and coupled with an electric vehicle.

10. The method of claim 9 , wherein the first biometric sensor includes a fingerprint reader and palmprint reader.

11. The method of claim 10 , wherein the first biometric sensor further includes a switch that, when depressed, is indicative of the charge request and the disconnection request.

12. The method of claim 10 , wherein the second biometric sensor is a fingerprint reader, palmprint reader, microphone, or camera.

13. The method of claim 12 , wherein the second biometric sensor is mounted on an outer surface of the electric vehicle in vicinity of an electric charge receptacle, on a door of the electric vehicle in vicinity of a door handle on the door, or on the outer surface of the electric vehicle in vicinity of the door handle.

14. The method of claim 9 , the biometric record comprising at least one of a thumbprint, a fingerprint, a paimprint, a retinal image, a facial image, a voice signature, and a voice signature of a code word.

15. A charge station for an electric vehicle comprising:

a plug having a first biometric sensor and configured to be coupled with the electric vehicle; and

a controller configured to,

responsive to detection of the plug coupled with the electric vehicle, engage a locking mechanism,

responsive to a removal request and a match between biometric data received from the first biometric sensor with a stored biometric record, disengage the locking mechanism,

responsive to a mismatch between the biometric data with the stored biometric record, activate a second biometric sensor that is different from the first biometric sensor, and

responsive to a mismatch between biometric data received from the second biometric sensor with the stored biometric record and an override command received from a user interface disposed within the electric vehicle, disengage the locking mechanism.

16. The charge station of claim 15 , wherein the stored biometric record includes data recorded from the first biometric sensor when the plug is coupled with a receptacle on the electric vehicle.

17. The charge station of claim 16 , wherein the first biometric sensor includes a fingerprint reader and a palmprint reader.

18. The charge station of claim 17 , wherein the first biometric sensor includes a switch that is mounted on the plug.

19. The charge station of claim 17 , wherein the palmprint reader is on a housing handle section of the plug.

20. The charge station of claim 16 , wherein the biometric record comprises at least one of a thumbprint, a fingerprint, a palmprint, a retinal image, a facial image, a voice signature, and a voice signature of a code word.
