Claim 0:
1. A battery thermal management system for an air vehicle comprising:
a liquid heat exchange circuit;
an air heat exchange circuit in selective fluid communication with an air heat sink;
a liquid-air heat exchanger positioned on the liquid heat exchange circuit and the air heat exchange circuit to exchange heat therebetween; and
at least one battery in thermal communication with the liquid heat exchange circuit, wherein the at least one battery is configured to at least one of charge or discharge to heat the at least one battery above a pre-determined minimum battery temperature;
a bypass line branching 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.
