TLDR
In this paper, a method and apparatus for transmitting wireless power to at least one wireless power receiver is described, which includes a communication unit that receives power management information from the at most one wireless receiver.Abstract:
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.read more
