Examples relate to thermal management systems for electric aircraft charging operations. A thermal conditioning system maintains coolant at controlled temperatures using a pressurized reservoir with an air separation system. A controller determines coolant composition by calculating density based on pressure measurements from a bottom-mounted sensor and volume measurements from multiple sources including float switches and flow sensors. The controller processes the measurements to determine glycol-to-water ratio and validates the calculations using conductivity sensing. The system maintains coolant temperature while regulating reservoir pressure through a pressurized headspace. An air separation system removes entrapped gases to maintain thermal conductivity. The system enables continuous monitoring and control of coolant properties during charging operations to maintain optimal battery pack temperatures.
