Abstract
Various embodiments of a transcutaneous energy transfer system are disclosed. The system includes an internal component adapted to be disposed within a body of a patient and an external component adapted to be disposed outside the body of the patient. The external component includes an external controller that is adapted to determine whether an internal coil of the internal component is electromagnetically disconnected from an external coil of the external component. If electromagnetically disconnected, then the external controller is adapted to determine 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, or a power consumption value of an implantable device, and output a charging alarm if a time interval when the internal coil is electromagnetically disconnected from the external coil exceeds the reconnection time threshold.
