Beschreibung
Zusammenfassung:	A heat pump system for use in a vehicle having a passenger compartment, and a thermal storage medium is provided. A method for providing heat to a vehicle passenger compartment is also provided. The vehicle may have an electric only vehicle mode wherein the vehicle may occupy one of an active electric drive state and an inactive state. The heat pump system may include a thermal storage medium configured to store heat produced during the inactive state. The thermal storage medium may be a device which has a thermal capacity exchangeable with a fluid medium such as a rechargeable energy storage system (RESS) or a phase change material. The heat stored by the thermal storage medium during the vehicle charge event may be transmitted from the thermal storage medium to the passenger compartment via the heat pump system during the active electric drive state.
