Abstract: A method of controlling a wireless power receiver. The method includes receiving, by a power receiver, power from a wireless power transmitter; receiving, from the wireless power transmitter, a time set value that is set for checking cross connection; in response to receiving the time set value, generating a power variation in the wireless power receiver by converting a load status from a first load status to a second load status; and maintaining the second load status for a time corresponding to the received time set value.

Abstract: A method and power transmitter for efficiently controlling power transmission to one or more power receivers in a wireless multi-power transmission system are provided. The method includes performing, when a predetermined measurement cycle arrives, a load measurement; comparing a current load measurement value with a previous load measurement value; determining whether the current load measurement value is increased over the previous load measurement value by at least as much as a first predetermined threshold; gradually increasing, when the load measurement value is increased over the previous load measurement value by at least as much as the first threshold, a transmission power value until a request for a subscription to a wireless multi-power transmission network from a power reception target within a predetermined time limit; and stopping, when the request for the subscription is not received before the time limit is exceeded, power transmission to the power reception target.

Abstract: The present invention relates to a method for adjusting a power information transmission period from a mobile terminal to be charged in a wireless charging apparatus. To this end, a wireless charging apparatus according to the present invention comprises: a communication unit for receiving power information from at least one mobile terminal; and a control unit for determining a transmission period of power information for each of the at least one mobile terminal based on the power information and adjusting the transmission period according to whether the power information is received from the at least one mobile terminal. As described above, the waste of resources, which may occur due to unnecessary packet transmission, can be reduced by adaptively adjusting the transmission period, thereby increasing the efficiency of power transmission.
