Claim 9:
10. A method for controlling a thermal management system for an air vehicle comprising:
determining if at least one battery is within a thermal range of operation for heating, wherein the battery is in thermal communication with a liquid heat exchange circuit, wherein a liquid-air heat exchanger is positioned on the liquid heat exchange circuit and an air heat exchange circuit to exchange heat therebetween, wherein the air heat exchange circuit is in selective fluid communication with an air heat sink, wherein a bypass line branches from the liquid heat exchange circuit upstream from the liquid-air heat exchanger and reconnecting to the liquid heat exchange circuit downstream from the liquid-air heat exchanger; and at least one of charging or discharging the at least one battery to heat the at least one battery above a pre-determined minimum battery temperature if the at least one battery is within the thermal range of operation for heating.
