Method and apparatus for wirelessly charging multiple wireless power receivers

摘要

A method and apparatus are provided for transmitting wireless power to at least one wireless power receiver. The apparatus includes a communication unit that receives power management information from the at least one wireless power receiver, wherein the power management information includes a power capacity of each of the at least one wireless power receiver; and a controller that analyzes the power management information and determines whether an output capacity of the wireless power transmitter is greater than a total sum of the power capacities of the at least one wireless power receiver.

主权项

1. A wireless power transmitter for transmitting wireless power to at least one wireless power receiver, the wireless power transmitter comprising:
a communication unit that receives power management information from each of the at least one wireless power receiver, wherein the power management information includes a power capacity of each of the at least one wireless power receiver; and a controller that:
analyzes the power management information,identifies whether an output capacity of the wireless power transmitter is greater than a total sum of the power capacities of the at least one wireless power receiver,selects a charging priority identifying method for identifying a charging priority of the at least one wireless power receiver from a plurality of charging priority identifying method candidates, if the output capacity of the wireless power transmitter is less than or equal to the total sum of the power capacities of the at least one wireless power receiver,identifies the charging priority of each of the at least one wireless power receiver according to the selected charging priority identifying method, andidentifies at least one wireless power receiver to be charged according to the charging priority of the at least one wireless power receiver.
