1. An external device, comprising:
a transceiver configured to communicate with a wireless charger device, wherein the wireless charger device is configured to provide energy to an implantable medical device (IMD);
at least one processing circuit including at least one processing device and at least one memory device, wherein the at least one memory device stores instructions that, when executed by the at least one processing device, causes the external device to:
obtain one or more power parameters detected by a sensing circuit in the charger device;
estimate a temperature range of the IMD using the one or more power parameters from the charger device; and
determine to recommend coupling at least one spacer to the charger device using the estimated temperature range of the IMD.
