Increasing efficiency of wireless power transfer
First Claim
1. A method comprising:
- wirelessly receiving power for a first period of time at a portable electronic device from a charging station via a wireless power link having a first transmission efficiency;
providing at least one parameter regarding the portable electronic device with respect to receipt of the power during the first period of time to the charging station via a wireless communication link; and
wirelessly receiving power for a second period of time at the portable electronic device from the charging station via the wireless power link having a second transmission efficiency that is greater than the first transmission efficiency in response to providing the at least one parameter to the charging station.

Abstract
Techniques are described herein that are capable of increasing efficiency of wireless power transfer. A wireless power transfer system includes features that allow the system to be deployed in public spaces such as airports or in commercial establishments such as restaurants or hotels to allow a user to recharge one or more portable electronic devices while away from home. To accommodate wireless recharging of a variety of device types and states, the system may receive parameters and/or state information associated with a portable electronic device to be recharged and may control the wireless power transfer in accordance with such parameters and/or state information. For instance, the system may increase efficiency of the wireless power transfer based on such parameters and/or state information. The system may also provide a secure and efficient means for obtaining required payment information from the user prior to the wireless power transfer, thereby facilitating fee-based recharging.
