Abstract

A wireless charger can determine a power requirement associated with operating at least a first device at a scheduled time. The wireless charger can determine a power emission level for the wireless charger based, at least in part, on the power requirement, such that the power emission level will provide sufficient wireless energy to satisfy the power requirement. The wireless charger can transmit wireless energy at the power emission level to cause the device to operate.

7. The method of claim 1, further comprising:

shifting the first device from the first operational state to a second operational state at a second scheduled time, wherein the second scheduled time is determined according to the schedule of operation;

transmitting a second amount of wireless energy to the first device at the second scheduled time, wherein the second amount of wireless energy is based, at least in part, on the power requirement associated with operating the first device at the second operational state;

shifting the first device from the second operational state to a shut-off state according to the schedule of operation; and

discontinuing transmission of the second amount of wireless energy to the first device.

8. The method of claim 1, wherein determining the power requirement comprises:

determining a plurality of devices in a wireless charging field of the wireless charger;

determining a plurality of device power requirement schedules corresponding to the plurality of devices; and

wherein the power requirement for the scheduled time comprises a maximum power requirement for the scheduled time from among the plurality of device power requirement schedules.

9. The method of claim 1, further comprising:

estimating an amount of other wireless energy to be delivered to the first device from one or more other wireless chargers; and

reducing the power requirement by the amount of other wireless energy.

10. The method of claim 9, further comprising:

coordinating with the one or more other wireless chargers to determine the amount of other wireless energy to be delivered from the one or more other wireless chargers, wherein both of at least a first wireless charger and a second wireless charger contribute portions of wireless energy to satisfy the power requirement associated with operating the first device at the scheduled time.
