Systems and methods for charging an electric vehicle at a charging station

1. A method of charging an electric vehicle having charge-receiving electrodes at a charging station having charging electrodes, comprising:

transmitting data between the electric vehicle and the charging station;

docking the electrical vehicle at the charging station based at least on a portion of the transmitted data, wherein the docking includes:

positioning the electric vehicle at the charging station such that the charge-receiving electrodes of the vehicle are positioned proximate the charging electrodes of the charging station;

automatically connecting the charge-receiving electrodes of the vehicle with the charging electrodes of the charging station; and

automatically engaging a brake of the electric vehicle; and

activating current flow from the charging station to the electric vehicle for charging after automatically engaging the brake.

2. The method of claim 1 , wherein the transmitting data includes transmitting the data when the electric vehicle is approaching the charging station.

3. The method of claim 1 , wherein the transmitting data includes transmitting data including at least one of (i) a state of charge of a battery of the electric vehicle, (ii) location of the electric vehicle relative to the charging station, (iii) electric vehicle identification information, and (iv) orientation of the electric vehicle.

4. The method of claim 1 , further including automatically identifying the electric vehicle as the electric vehicle approaches the charging station.

5. The method of claim 4 , wherein the automatically identifying includes using an RFID reader on the charging station to read an RFID tag on the electric vehicle as the electric vehicle moves towards the charging station.

6. The method of claim 1 , wherein positioning the electric vehicle includes using data from one or more sensors located on the electric vehicle or the charging station to position the electric vehicle.

7. The method of claim 1 , further including detecting movement of the electric vehicle during charging and stopping the charging if movement is detected.

8. The method of claim 1 , wherein positioning the electric vehicle includes moving the electric vehicle towards the charging station at a speed controlled by the charging station.

9. The method of claim 1 , further including determining if the approaching electric vehicle is supposed to be charged at the charging station using the transmitted data, and wherein docking the electric vehicle includes docking the electric vehicle only if it is determined that the approaching electric vehicle is supposed to be charged at the charging station.

10. The method of claim 1 , wherein the electric vehicle is a heavy duty vehicle.

11. A method of charging an electric vehicle having charge-receiving electrodes at a charging station having charging electrodes, comprising:

exchanging data between the electric vehicle and the charging station as the electric vehicle approaches the charging station;

positioning the electric vehicle at the charging station such that the charge-receiving electrodes of the vehicle are positioned proximate the charging electrodes of the charging station;

after the positioning, automatically decreasing a gap between the charging electrodes and the charge-receiving electrodes;

connecting the charging electrodes with the charge-receiving electrodes;

automatically locking movement of the vehicle; and

activating current flow from the charging station to the electric vehicle for charging after automatically locking movement.

12. The method of claim 11 , wherein decreasing the gap includes moving the charging electrodes towards the charge-receiving electrodes.

13. The method of claim 11 , further including identifying the electric vehicle using the data.

14. The method of claim 11 , wherein automatically locking movement includes automatically shifting a transmission of the electric vehicle to neutral.

15. The method of claim 11 , further including determining whether the electric vehicle approaching the charging station is supposed to be charged at the charging station using the data.

16. The method of claim 15 , wherein decreasing the gap includes decreasing the gap only if it is determined that the approaching electric vehicle is supposed to be charged at the charging station.

17. The method of claim 11 , wherein the electric vehicle is a heavy duty vehicle.

18. A method of charging an electric vehicle having charge-receiving electrodes at a charging station having charging electrodes, comprising:

exchanging data between the electric vehicle and the charging station as the electric vehicle approaches the charging station;

using one or more sensors positioned on the charging station or the electric vehicle to assist in aligning the electric vehicle with the charging station as the electric vehicle approaches the charging station;

positioning the electric vehicle such that the charge-receiving electrodes of the electric vehicle are positioned proximate the charging electrodes of the charging station;

decreasing a gap between the charging electrodes and the charge-receiving electrodes;

establishing electrical connection between the charging electrodes and the charge-receiving electrodes;

automatically engaging a brake of the electric vehicle to resist movement of the vehicle; and

charging the electric vehicle after automatically engaging the brake.

19. The method of claim 18 , wherein automatically engaging the brake includes automatically shifting a transmission of the electric vehicle to neutral.

20. The method of claim 18 , further including determining that the electric vehicle approaching the charging station is supposed to be charged at the charging station prior to decreasing the gap.
