Abstract
A method is provided and includes activating, by a controller, a compressor of an HVAC subsystem when heating of a passenger compartment is required and determining whether a heat rejection from a powertrain component is greater than or equal to a reference heat rejection. A powertrain-side pump is activated and a battery-side pump is stopped when the heat rejection is greater than or equal to the reference heat rejection. A refrigerant circulating in the HVAC subsystem exchanges heat with a powertrain coolant having absorbed heat from the powertrain component.
