Claims7
A method for transferring wireless power using a wireless power transmission apparatus, the method comprising:
- transmitting a power transfer request packet to at least one wireless charging device during a request period;
- receiving a power transfer response packet from the at least one wireless charging device during a response period;
- transmitting, during the response period, a power transfer beacon request packet comprising information on a wireless power transfer schedule to the at least one wireless charging device in response to receiving the power transfer response packet;
- and
- transmitting wireless power to the at least one wireless charging device according to the wireless power transfer schedule during the response period,
- wherein the transmitting the power transfer beacon request packet comprises:
- dividing the response period into at least one time slot based on a number of the at least one wireless charging device;
- and
- generating the wireless power transfer schedule assigning the at least one time slots to the at least one wireless charging device.
