Abstract
The present disclosure provides a method of managing thermal loads in the powertrain of an electric vehicle and controlling various electronic components of a powertrain thermal management system. The method may include heating a coolant of a powertrain coolant loop utilizing waste heat from a liquid-cooled powertrain component (e.g., an electric motor, a DC-DC converter, etc.), measuring a coolant temperature, and utilizing combined feedforward and feedback control methods for different components (pump(s), radiator fan(s), valve(s)) of the powertrain thermal management system.
