Abstract

A vehicle assembly includes, a traction battery and a heating unit. The heating unit is disposed within a cargo bed of a vehicle and selectively powered by the traction battery. A heating unit powering method includes powering a heating unit within a cargo bed of a vehicle using a traction battery of the vehicle.

First claim

What is claimed is:

1. A vehicle assembly, comprising:
a traction battery; and
a heating unit disposed within a cargo bed of a vehicle and selectively powered by the traction battery; and
a side shelf that is moveable between an extended position where the side shelf extends from a tailgate and a retracted position where the side shelf is retracted within the tailgate, wherein the side shelf covers the heating unit when in the retracted position and reveals the heating unit when in the extended position.

2. The vehicle assembly of claim 1 , further comprising a cover movable between a closed position that covers the heating unit and an open position that exposes the heating unit.

3. The vehicle assembly of claim 2 , wherein the heating unit is disposed within a tailgate of the cargo bed.

4. The vehicle assembly of claim 3 , wherein the tailgate has a first cross-vehicle width and the cover has a second cross-vehicle width that is fifty percent or less of the first cross-vehicle width.

5. The vehicle assembly of claim 2 , further comprising an interlock configured to transition between a locked position that holds the cover in the open position and an unlocked position that permits movement of the cover to the closed position in response to a thermal energy level.

6. The vehicle assembly of claim 1 , further comprising an inverter that converts direct current from the traction battery to alternating current for use by the heating unit.

7. The vehicle assembly of claim 1 , wherein the heating unit is an electric stove.

8. The vehicle assembly of claim 1 , wherein the traction battery selectively powers an electric drivetrain of the vehicle.

9. The vehicle assembly of claim 1 , wherein the traction battery is mounted to the vehicle and disposed outside of a tailgate of the cargo bed.

10. The vehicle assembly of claim 1 , wherein the vehicle is a plug-in hybrid vehicle configured to recharge the traction battery using a grid power source, wherein the traction battery is configured to power the heating unit while recharging from the grid power source.

11. A heating unit powering method, comprising:
powering a heating unit within a cargo bed of a vehicle using a traction battery of the vehicle;
housing the heating unit within a tailgate of the vehicle; and
extending a side shelf laterally from the tailgate to reveal the heating unit, and retracting the side shelf to cover the heating unit.

12. The heating unit powering method of claim 11 , wherein the heating unit is an electric stove.

13. The heating unit powering method of claim 11 , further comprising charging the traction battery from a grid power source during the powering.

14. The heating unit powering method of claim 11 , further comprising, during the powering, converting direct current from the traction battery to alternating current for use by the heating unit.
