Abstract

A power supply system for an electrified vehicle according to an exemplar aspect of the present disclosure includes, among other things, a primary power source and an auxiliary power source configured to selectively supply power in place of or in addition to the primary power source. At least one electrical connector is configured to connect the auxiliary power source to the power supply system.

Claims

1. A power supply system for an electrified vehicle, comprising:

a primary power source;

an auxiliary power source configured to selectively supply power in place of or in addition to said primary power source; and

at least one electrical connector configured to connect said auxiliary power source to said power supply system.

2. The system as recited in claim 1, wherein said primary power source is a high voltage battery.

3. The system as recited in claim 1, wherein said auxiliary power source is a portable generator.

4. The system as recited in claim 1, wherein said auxiliary power source is configured to selectively offload energy demand from said primary power source.

5. The system as recited in claim 1, wherein said at least one electrical connector is disposed near a rear end of said electrified vehicle or under a hood of said electrified vehicle.

6. The system as recited in claim 1, comprising a plurality of different electrical connectors incorporated into said power supply system.

7. The system as recited in claim 1, wherein said auxiliary power source is disposed on a shelving assembly mountable to a trailer hitch of said electrified vehicle.

8. The system as recited in claim 1, comprising a cluster display configured to select a load to place on said auxiliary power source.

9. The system as recited in claim 8, wherein said cluster display includes at least a display unit and at least one input device.

10. The system as recited in claim 1, comprising a control unit configured to sense power communicated to said at least one electrical connector.

11. A method, comprising:

activating an accessory system of an electrified vehicle;

offloading a portion of an energy demand of a primary power source to an auxiliary power source; and

powering the accessory system with the auxiliary power source.

12. The method as recited in claim 11, wherein the accessory system is one of a climate control system, a lighting system, a consumer device powering station, or an electrically driven system.

13. The method as recited in claim 11, comprising the step of:

prior to the step of offloading, selecting a load to place on the auxiliary power source.

14. The method as recited in claim 13, comprising the step of:

automatically reducing the load placed on the auxiliary power source in response to a fault condition of said auxiliary power source.

15. The method as recited in claim 11, comprising at least one of the steps of:

charging the primary power source with the auxiliary power source;

or

operating the electrified vehicle in a reduced power mode with the auxiliary power source.

16. A method, comprising:

providing at least one electrical connector on an electrified vehicle; and

supplying power to the at least one electrical connector via an auxiliary power source to at least temporarily supply power to the electrified vehicle.

17. The method as recited in claim 16, comprising at least one of the steps of:

charging a primary power source with the auxiliary power source;

or

operating the electrified vehicle in a reduced power mode with the auxiliary power source.

18. The method as recited in claim 16, comprising the steps of:

activating an accessory system of an electrified vehicle; and

offloading a portion of an energy demand of a primary power source to power the accessory system with the auxiliary power source.

19. The method as recited in claim 16, comprising the step of:

operating the electrified vehicle using the power from the auxiliary power source where other power is unavailable.

20. The method as recited in claim 16, comprising the step of:

selecting a load to place on the auxiliary power source prior to the step of supplying.
