A battery thermal management system for an air vehicle includes a liquid heat exchange circuit (116), an air heat exchange circuit (114), and a liquid-air heat exchanger (112). The liquid-air heat exchanger (112) is positioned on the liquid heat exchange circuit (116) and the air heat exchange circuit (114) to exchange heat therebetween. The system includes a coolant pump (109) fluidically connected to the liquid heat exchange circuit (116), a flow restrictor positioned in the liquid heat exchange circuit (116), and a battery (104) in thermal communication with the liquid heat exchange circuit (116). A method for controlling a thermal management system for an air vehicle includes sensing a temperature of a battery with a temperature sensor, varying a flow area of a flow path through a liquid heat exchange circuit with the flow restrictor if the temperature is below a pre-determined threshold, and operating a pump to provide heating to the battery if the temperature is below the pre-determined threshold.
