Abstract

A charge termination system according to an exemplary aspect of the present disclosure includes, among other things, a switch configured to transition from a first position to a second position and a charging circuit extending to an external power source. The switch in the first position permits the charging circuit to charge an electrified vehicle. The switch in the second position prevents the charging circuit from charging the electrified vehicle.

Claims

1. A charge termination system, comprising:

a switch configured to transition from a first position to a second position; and

a charging circuit extending to an external power source, the switch in the first position permitting the charging circuit to charge an electrified vehicle, the switch in the second position preventing the charging circuit from charging the electrified vehicle.

2. The charge termination system of claim 1, wherein the switch is a passive switch.

3. The charge termination system of claim 2, wherein the switch is an inertia switch.

4. The charge termination system of claim 1, wherein the switch is configured to transition from the first position to the second position in response to movement of the electrified vehicle relative to a charging station.

5. The charge termination system of claim 1, wherein the switch is within the electrified vehicle.

6. The charge termination system of claim 5, wherein the switch is at least partially within a receptacle that engages a vehicle charger plug of the charger assembly.

7. The charge termination system of claim 1, further comprising a charging cord of a charger assembly, the charging cord holding the switch.

8. The charge termination system of claim 1, further comprising a vehicle charger plug of a charger assembly, the vehicle charger plug holding the switch.

9. The charge termination system of claim 1, wherein the switch in the first position permits the charging circuit to charge the electrified vehicle when the electrified vehicle is stationary.

10. The charge termination system of claim 1, wherein the switch is configured to transition from the first position to the second position when the electrified vehicle is in a key-off state.

11. An electrified vehicle charge termination method, comprising:

charging an electrified vehicle using a charging station; and

in response to a relative movement between the electrified vehicle and the charging station, transitioning a switch from a first position that permits the charging to a second position that prevents the charging.

12. The electrified vehicle charge termination method of claim 11, wherein the electrified vehicle is keyed-off during the charging.

13. The electrified vehicle charge termination method of claim 11, wherein the switch is an inertia switch.

14. The electrified vehicle charge termination method of claim 11, wherein the switch is a passive switch.

15. The electrified vehicle charge termination method of claim 11, further comprising holding the switch within the electrified vehicle.

16. The electrified vehicle charge termination method of claim 11, further comprising holding the switch within a vehicle charger plug of the charger assembly.

17. The electrified vehicle charge termination method of claim 11, further comprising holding the switch within a charger cable of the charger assembly.

18. The electrified vehicle charge termination method of claim 11, wherein the switch opens a charging circuit extending between a grid power source and the electrified vehicle.

19. The electrified vehicle charge termination method of claim 11, wherein a restraint control module of the electrified is off during the charging.

20. The electrified vehicle charge termination method of claim 11, further comprising transmitting a communication from the electrified vehicle in response to the relative movement, the transitioning, or both.
