WIRELESS INDUCTIVE POWER TRANSMISSION Russian patent published in 2019 - IPC H02J50/10 

FIELD: electrical engineering.

SUBSTANCE: system for wireless transmission of energy comprises an energy transmitter, which generates a wireless energy signal, which provides energy to a plurality of energy receivers (105, 109). Power transmitter (101) comprises receiver (203) receiving data messages from energy receivers (105, 109) via load modulation channel divided into time slots. Processor (205) of time slots distributes time slots as dedicated time slots for individual energy receivers or as common time slots for load modulation by any energy receiver (105, 109). Identification data controller (207) associates time identification data with each of energy receivers (105), and message processor (209) determines a source energy receiver for messages in response to information of temporary identification data in messages. In particular, message processor (209) determines source for first message received in common time slot as first energy receiver (105), if the information of the temporary identification data in the first message indicates the time identification data assigned to the first energy receiver (105).

EFFECT: creation of improved wireless energy transfer with increased flexibility, high efficiency, improved compatibility with the previous version, improved control of communication and improved support of multiple energy receivers.
