Abstract: A method of monitoring heating of a hermetic package of an implanted transcutaneous energy transfer system (TETS) coil, the method includes monitoring a power transfer between the implanted TETS coil and an external TETS coil; detecting an amount of power lost during the power transfer; determining if the amount of power lost during the power transfer is above a first predetermined threshold; if the power lost is above the first predetermined threshold, determining if a misalignment between the implanted TETS coil and the external TETS coil is greater than a predetermined distance; and if the misalignment is greater than the predetermined distance, generating an alert to align the external TETS coil with the implanted TETS coil.
