  • Patent number: 11075548
    Abstract: Embodiments described herein provide a method for wireless power transmission of reconfigurable power levels. A wireless power receiver is used to receive power from a wireless power transmitter according to a negotiated power level. The wireless power receiver determines whether a re-negotiation condition is met at the wireless power receiver. The wireless power receiver then sends, to the wireless power transmitter, a re-negotiation request for an updated power level different from the negotiated power level. The wireless power receiver receives, from the wireless power transmitter, an acknowledgement that acknowledges the updated power level, and then operates to receive power from the wireless power transmitter according to the updated power level.
