Abstract
Systems and methods pertaining to multi-frequency wireless power transfer are disclosed. In one exemplary implementation, a wireless charger is used to generate and transmit two wireless power charges at two different frequencies, using a frequency division multiplexed (FDM) format. A wireless sly chargeable device that is inductively coupled to the wireless charger receives the two wireless power charges in the FDM format and uses the two charges to charge one or more chargeable batteries contained in the wirelessly chargeable device.
