Abstract: Example methods calibrate battery models in electric aircraft using closed-loop feedback. Test points gaps are received. The aircraft connects to ground support equipment (GSE) and is immobilized. Certain battery packs are selected for testing. Propellers are ramped to create power draws per a test plan while monitoring voltage, current, and temperature telemetry. Selective battery packs are activated to focus loads. Telemetry data is processed and stored. Rest periods allow battery temperature stabilization between test points. Additional packs are tested if needed. Battery models are updated by analyzing telemetry data. Overall, the method maintains customized, accurate battery models using lab testing and in-situ calibration with the GSE. Frequent and ongoing recalibration via closed-loop feedback replaces assumptions with observed data for high-fidelity state-of-health predictions throughout the battery lifetime.

Abstract: A system for benchmarking a flowline temperature model using acoustic detection techniques is disclosed. A predicted velocity of a pressure wave introduced into the flowline by an acoustic detection subsystem can be determined using temperature data from a known temperature model, and an expected time of flight of the pressure wave to a flowline target feature can be calculated using the predicted velocity. An actual time of flight of the pressure wave to the target feature can also be observed from received pressure data, and when the system detects a difference between the actual and predicted times of flight, an actual pressure wave velocity may be calculated based on the actual time of flight. A corrected temperature value corresponding to the actual pressure wave velocity may be subsequently calculated, and the known temperature model can be revised by substituting the corrected temperature value for the predicted temperature value.
