1. A battery thermal management system for an air vehicle comprising:
a liquid heat exchange circuit;
at least one battery in thermal communication with the liquid heat exchange circuit;
a controller operatively connected to the liquid heat exchange circuit by way of a pump operatively connected to the liquid heat exchange circuit, wherein the controller is operatively connected to the pump and configured and adapted to select whether or not the pump of the liquid heat exchange circuit is “ON” or “OFF”; and
at least one heat exchanger positioned on the liquid heat exchange circuit, wherein the at least one heat exchanger is a liquid-air heat exchanger, wherein the liquid-air heat exchanger is positioned on an air heat exchange circuit configured and adapted to receive air; and
a temperature sensor operatively connected to the air heat exchange circuit upstream from the liquid-air heat exchanger and downstream from an air source, wherein the temperature sensor is positioned to measure a total air temperature of air entering the air source.
