Abstract

An apparatus for preconditioning a cabin of a non-electric vehicle uses power supplied from a source that is external to the vehicle, such as an electrical utility power grid. The non-electric vehicle includes an internal combustion engine, a battery, and an electric machine drive unit that supplies electrical energy to the battery when driven by the internal combustion engine. A mechanically operated preconditioning device is provided that can be driven by the engine when the internal combustion engine is operating and that can be driven by the electric machine drive unit when the internal combustion engine is not operating. An AC/DC converter is adapted to receive electrical energy from an external source and to supply such electrical energy through the battery to power the electric machine drive unit to drive the mechanically operated preconditioning device when the internal combustion engine is not operating.

Claims

1. A vehicle comprising:

an engine;

a battery;

an electric machine driven by the engine and supplying energy to the battery;

a preconditioning device driven by the engine when it is operating and driven by the electric machine when it is not operating; and

an AC/DC converter receiving energy from an external source and supplying such energy through the battery to power the electric machine to drive the preconditioning device when the engine is not operating.

2. The vehicle defined in claim 1 wherein the internal combustion engine rotatably drives a pulley, and wherein the pulley is connected to a second pulley which is connected through a clutch to rotatably drive the electric machine drive unit.

3. The vehicle defined in claim 2 wherein the clutch allows the pulley to drive the electric machine drive unit but selectively allows the electric machine drive unit to drive the pulley.

4. The vehicle defined in claim 3 wherein the clutch is a first clutch, and wherein the electric machine drive unit is connected through a second clutch to rotatably drive the mechanically operated preconditioning device.

5. The vehicle defined in claim 2 wherein the AC/DC converter is supported on the electric vehicle.

6. The vehicle defined in claim 2 wherein the AC/DC converter is provided externally of the electric vehicle.

7. The vehicle defined in claim 1 wherein the internal combustion engine is connected through a clutch to rotatably drive a pulley, and wherein the pulley rotatably drives the electric machine drive unit.

8. The vehicle defined in claim 7 wherein the clutch allows the internal combustion engine to drive the pulley but selectively allows the pulley to drive the internal combustion engine.

9. The vehicle defined in claim 1 wherein the AC/DC converter is supported on the electric vehicle.

10. The vehicle defined in claim 1 wherein the AC/DC converter is provided externally of the electric vehicle.

11. A non-electric vehicle comprising:

an internal combustion engine;

a battery;

an electric machine drive unit that is driven by the internal combustion engine and that supplies electrical energy to the battery;

a mechanically operated preconditioning device that can be driven by the engine when the internal combustion engine is operating and that can be driven by the electric machine drive unit when the internal combustion engine is not operating; and

an AC/DC converter that is adapted to receive electrical energy from an external source and to supply such electrical energy through the battery to power the electric machine drive to drive the mechanically operated preconditioning device when the internal combustion engine is not operating.

12. The non-electric vehicle defined in claim 11 wherein the internal combustion engine rotatably drives a pulley, and wherein the pulley is connected to a second pulley which is connected through a clutch to rotatably drive the electric machine drive unit.

13. The non-electric vehicle defined in claim 12 wherein the clutch allows the pulley to drive the electric machine drive unit but selectively allows the electric machine drive unit to drive the pulley.

14. The non-electric vehicle defined in claim 13 wherein the clutch is a first clutch, and wherein the electric machine drive unit is connected through a second clutch to rotatably drive the mechanically operated preconditioning device.

15. The non-electric vehicle defined in claim 12 wherein the AC/DC converter is supported on the non-electric vehicle.

16. The non-electric vehicle defined in claim 12 wherein the AC/DC converter is provided externally of the non-electric vehicle.

17. The non-electric vehicle defined in claim 11 wherein the internal combustion engine is connected through a clutch to rotatably drive a pulley, and wherein the pulley rotatably drives a third pulley which drives the electric machine drive unit.

18. The non-electric vehicle defined in claim 17 wherein the first clutch allows the internal combustion engine to drive the pulley but selectively allows the pulley to drive the internal combustion engine.

19. The non-electric vehicle defined in claim 11 wherein the AC/DC converter is supported on the non-electric vehicle.

20. The non-electric vehicle defined in claim 11 wherein the AC/DC converter is provided externally of the non-electric vehicle.
