1. A wireless charger of an implantable medical system, comprising:
- a charger power supply;
an inductive coil;
a circuit configured to route power provided by the charger power supply to the inductive coil for transcutaneous transfer of the power to an implantable component, and to route power received via the inductive coil from an auxiliary charger to the charger power supply for recharging of the charger power supply; and
wherein the wireless charger is configured to detect the presence of an inductive field generated by the auxiliary charger, and wherein in response to detection of the presence of the inductive field generated by the auxiliary charger, the circuit is automatically arranged to route power from the inductive coil to the charger power supply.
