摘要：
Certain aspects of the present disclosure generally relate to methods and apparatus for wirelessly charging a device having a wireless power receiver with a dead battery. One example method for safely wirelessly charging an implantable device, with an apparatus, generally includes determining that the implantable device has a dead battery； based on the determination, wirelessly transmitting power from the apparatus at an initial level for a first interval； checking for a first signal received from the implantable device during or at an end of the first interval or a period associated with the initial level； and if no first signal is received from the implantable device, increasing the transmitted power to a higher level for a second interval.
