Abstract
Official abstract text for this publication.
Methods and system for providing heat to a vehicle are presented. In one example, a heat pump supplies thermal energy to an engine to reduce engine emissions during engine starting. Further, heating the engine via the heat pump may also reduce engine friction at colder ambient temperatures where oil viscosity may be increased.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for heating a vehicle, comprising: selectively operating a vehicle vapor compression heat pump system of the vehicle when the vehicle is electrically coupled to a stationary electrical power grid; and via activating at least the vehicle vapor compression heat pump system, transferring heat from a passenger cabin to a refrigerant in a heat pump system via an interior heat exchanger, transferring heat from the refrigerant to glycol coolant in…
