INDUCTIVE WIRELESS TRANSFER OF POWER WITH THE USE OF INTERCONNECTION WITH TIME SLOTS Russian patent published in 2018 - IPC H02J50/80 

FIELD: electrical engineering.

SUBSTANCE: method is provided for allocating communication slots contained in the repeated frames for communication between an inductive wireless power transmitter and at least two inductive wireless power receivers, wherein power transmitter and power receivers are configured to communicate by modulating and demodulating an inductive power signal. Transmitter sends synchronization messages indicating the beginning of communication time slots and frames, and messages indicating that the time slot is not allocated. Receiver may send, for an unallocated time slot, a message to the transmitter requesting allocation of an unallocated communication slot. Transmitter then sends messages to indicate whether the message was successfully received and if a request for allocation is provided.

EFFECT: enabling communication between one inductive wireless power transmitter and a plurality of inductive wireless power receivers.
