Abstract

A method for wirelessly charging a battery in an implantable medical device including the steps of: providing a receiver in the implantable medical device and providing a temperature sensor in the implantable medical device. The method also includes receiving, via the receiver, a wireless power signal from an external charger and converting the wireless power signal into a battery charge signal including power for recharging the battery. The method yet also includes sensing a temperature of the implantable medical device with the temperature sensor. The method further includes changing a current of the battery charge signal from a first non-zero current to a second non-zero current that is different from the first non-zero current. Changing of the current of the battery charge signal is based on the temperature sensed by the temperature sensor.
