Systems and methods for optimally delivering pulsed wireless power

摘要

A transmitter assembly is useful in optimizing in the delivery of wireless power to a plurality of receivers. Each receiver measures its own battery need for power and transmits that measurement as a request to the transmitter. The transmitter is configured to normalize and compare battery need requests. The transmitter then allocates pulses of wireless power among the requesting receivers according to their battery need.

主权项

1. A method of delivering pulsed wireless power to wireless power receivers using a power transmitter assembly having a phased array with multiple antennae, the method comprising:
receiving one or more battery charging need requests initiated by one or more of the wireless power receivers; allocating a plurality of sequential wireless power pulses of a power burst to the wireless power receivers in accordance with the corresponding battery charging need requests; and delivering wireless power to the wireless power receivers via the allocated sequential wireless power pulses of the power burst, wherein the power pulses are sequentially delivered to different ones of the wireless power receivers by modifying one or more phases of the multiple antennae of the phased array.
