1. A wireless power reception method of a wireless power receiver comprising:
- receiving a first available power value of a wireless power transmitter from the wireless power transmitter;
determining, by the wireless power receiver, a first demanded power value of the wireless power receiver from among available power values that are less than or equal to the first available power value of the wireless power transmitter, the first demanded power value of the wireless power receiver determined by the wireless power receiver being less than the first available power value of the wireless power transmitter, wherein the first demanded power value is different in a subsequent iteration of the determining the first demanded power value;
in response to determining, by the wireless power receiver, the first demanded power value of the wireless power receiver, transmitting, by the wireless power receiver, the first demanded power value of the wireless power receiver to the wireless power transmitter;
receiving, by the wireless power receiver, a first power from the wireless power transmitter, the first power being adjusted to approximately equal the first demanded power value of the wireless power receiver;
in response to a state of the wireless power transmitter changing, receiving, by the wireless power receiver, a second available power value of the wireless power transmitter from the wireless power transmitter, the second available power value being different than the first available power value of the wireless power transmitter;
determining, by the wireless power receiver, a second demanded power value of the wireless power receiver from among available power values that are less than or equal to the second available power value of the wireless power transmitter, wherein the determining the second demanded power value is the subsequent iteration of the determining the first demanded power value;
in response to determining, by the wireless power receiver, the second demanded power value of the wireless power receiver, transmitting, by the wireless power receiver, the second demanded power value to the wireless power transmitter; and
receiving, by the wireless power receiver, a second power from the wireless power transmitter, the second power being adjusted to approximately equal the second demanded power value of the wireless power receiver.
