Abstract
In an embodiment, a sub-surface wireless charger includes a transmitter coil and a controller. The controller is configured to generate a protective pulse having a first energy, determine a characteristic of the transmitter coil based on the generated protective pulse, determine whether it is safe to begin wireless charging based on the determined characteristic, and when the controller determines that it is safe to begin wireless charging, generate an operating pulse having a second energy, where the second energy is higher than the first energy.
