Abstract
A charging apparatus for a wearable device includes a transmitter-side antenna and a transmitter-side control system. The transmitter-side control system is configured to (i) during a first period of time that is prior to the wearable device entering an increased-temperature state, drive the transmitter-side antenna to emit an alternating electromagnetic field for delivering wireless power to the wearable device and (ii) during a second period of time when the wearable device is in the increased-temperature state, toggle between power-on and power-off sub-periods for driving the transmitter-side antenna. During each power-on sub-period, the transmitter-side antenna is driven to emit the alternating electromagnetic field for delivering wireless power to the wearable device. During each power-off sub-period, the transmitter-side antenna is not driven to emit the alternating electromagnetic field for delivering wireless power to the wearable device.
