The present disclosure relates to a method for providing compatibility with a wireless power transmitting device in a wireless power transmitting system. The method includes the steps of: detecting a wireless power receiving device on the basis of a load change; transmitting a request signal for requesting information for a receiving device to the wireless power receiving device; receiving the information for the receiving device from the wireless power receiving device, wherein the information selectively includes version information on standard technical specifications for realizing the wireless power receiving device; and, when the version information is included in the information for the receiving device, performing a wireless power transmitting operation according to the standard technical specifications corresponding to the version information.

Apparatus and method for providing compatibility in wireless power transmission system

The present invention relates to a method for providing compatibility with a wireless power transmitting device in a wireless power transmitting system. The method includes the steps of: detecting a wireless power receiving device on the basis of a load change; transmitting a request signal for requesting information for a receiving device to the wireless power receiving device; receiving the information for the receiving device from the wireless power receiving device, wherein the information selectively includes version information on standard technical specifications for realizing the wireless power receiving device; and, when the version information is included in the information for the receiving device, performing a wireless power transmitting operation according to the standard technical specifications corresponding to the version information.

The present invention is related to an apparatus and method for detecting a foreign object in a wireless power transmitting system. Specifically, a wireless power transmitting apparatus includes a primary core block which transmits wireless power to a wireless power receiving apparatus through magnetic induction or magnetic resonance; an electric driving unit applying an AC (Alternating Current) signal required for the primary core block to transmit the wireless power; a control unit being connected to the electric driving unit and generating a control signal for controlling the AC signal; and a current measurement unit measuring a current flowing into the primary core block and obtaining a current measurement value converted to a numeric value relevant for the control unit to analyze the current.
