Abstract

An exemplary reporting method includes the steps of receiving diagnostic data from electric vehicle supply equipment, and then reporting the diagnostic data through an interface of an electrified vehicle. An exemplary electrified vehicle assembly includes a controller of an electrified vehicle. The controller is configured to receive diagnostic data from electric vehicle supply equipment. The exemplary assembly further includes an interface of the electrified vehicle configured to report the diagnostic data.

Claims

1. A diagnostic reporting method, comprising:

receiving diagnostic data from electric vehicle supply equipment; and

reporting the diagnostic data through an interface of an electrified vehicle to a device different than the electrified vehicle.

2. The method of claim 1, further comprising reporting the diagnostic data using a controller area network (CAN) bus protocol.

3. The method of claim 1, wherein the interface is an on-board diagnostic (OBD) port.

4. The method of claim 1, wherein the diagnostic data is received from the electric vehicle supply equipment as a signal, and further comprising converting the signal to a diagnostic code prior to the reporting.

5. The method of claim 4, wherein the signal is a pulse width modulated signal.

6. The method of claim 4, further comprising converting the signal using a controller of the electrified vehicle.

7. The method of claim 6, wherein the controller is a battery charger control module that interfaces with a traction battery system of the electrified vehicle.

9. The method of claim 1, wherein the diagnostic data is received from a pilot line of the electric vehicle supply equipment.

10. The method of claim 1, further comprising charging a traction battery of the electrified vehicle using power sent to the electrified vehicle through the electric vehicle supply equipment from an external power source, the diagnostic data generated by the electric vehicle supply equipment.

11. The method of claim 1, wherein the electric vehicle supply equipment is a cordset.

21. The method of claim 2, wherein the device is a CAN tool external to the electrified vehicle.

8. (canceled)

12. A diagnostic method, comprising:

sending diagnostic data from electric vehicle supply equipment to an electrified vehicle for reporting to a controller area network (CAN) tool that is external to the electrified vehicle.

13. The method of claim 12, further comprising executing a self-test on the electric vehicle supply equipment to collect the diagnostic data generated by the electric vehicle supply equipment.

14. The method of claim 13, wherein the electric vehicle supply equipment is connected to an external power source and the electrified vehicle during both the self-test and the sending.

15. The method of claim 12, further comprising sending the diagnostic data to the electrified vehicle using a pilot line of the electric vehicle supply equipment.

16. An electrified vehicle assembly, comprising:

a controller of an electrified vehicle, the controller configured to receive diagnostic data from electric vehicle supply equipment; and

an interface of the electrified vehicle configured to report the diagnostic data to a device different than the electrified vehicle.

17. The electrified vehicle assembly of claim 16, wherein the interface is an on-board diagnostic (OBD) port configured to report the diagnostic data to a controller area network (CAN) tool using a CAN protocol.

18. The electrified vehicle assembly of claim 16, wherein the electrified vehicle includes a traction battery configured to charge using power transmitted from an external power source through the electric vehicle supply equipment to the vehicle.

19. The electrified vehicle assembly of claim 16, wherein the diagnostic data is received from a pilot line of the electric vehicle supply equipment.

20. The electrified vehicle assembly of claim 16, wherein the diagnostic data is received as a bit streamed signal.
