Abstract
Provided is a method for accounting for power loss. The method includes the steps of: acquiring information on a first distance between an upper surface of a coil of a wireless power transmitter and an upper surface of the wireless power transmitter, and a second distance between an upper surface of a coil of a reference transmitter and an upper surface of the reference transmitter; and estimating power loss due to friendly metal with reference to the acquired information.
Claims24
A method for accounting for power loss,
- wherein the method is implemented in a wireless power transmitter and comprises the steps of:
- by the wireless power transmitter, acquiring information on a first distance between an upper surface of a coil of the wireless power transmitter and an upper surface of an interface of the wireless power transmitter, and a second distance between an upper surface of a coil of a reference transmitter and an upper surface of an interface of the reference transmitter;
- and
- by the wireless power transmitter, estimating power loss due to friendly metal with reference to the acquired information,
- wherein the wireless power transmitter is configured to estimate the power loss after adjusting the second distance to match the first distance,
- wherein the friendly metal is a metal included in at least one of the wireless power transmitter and a wireless power receiver, and causes the power loss by absorbing a part of power transmitted during wireless power transmission and reception, and
- wherein the reference transmitter is a transmitter with standardized specifications.
