WIRELESS POWER TRANSMISSION APPARATUS AND METHOD
First Claim
1. A wireless power transmission apparatus for tracking a charging capacity of each of a plurality of wireless power reception apparatuses in an environment in which the plurality of wireless power reception apparatuses are charged, the wireless power transmission apparatus comprising:
- a communication unit configured to receive information about either one or both of a charging support power and a requested power from each of the plurality of wireless power reception apparatuses;
a controller configured to determine a charging capacity for a wireless power reception apparatus supporting the charging support power among the plurality of wireless power reception apparatuses based on the information about the charging support power received from the wireless power reception apparatus supporting the charging support power; and
a power tracker configured to re-track the determined charging capacity based on charging status information received from the plurality of wireless power reception apparatuses.
