Claim 9:
10. A method of outputting a charging alarm for a transcutaneous energy transfer system, the method comprising:
determining that an internal coil of an internal component of the transcutaneous energy transfer system is electromagnetically disconnected from an external coil of an external component of the transcutaneous energy transfer system;
determining a reconnection time threshold based upon at least one of a power transfer efficiency value between the internal coil and the external coil, a charge state of an internal power source of the internal component that is electrically connected to the internal coil, or a power consumption value of an implantable device of the internal component that is electrically connected to the internal power source; and
outputting the charging alarm based on a time interval when the internal coil is disconnected from the external coil exceeding the reconnection time threshold.
