Abstract

Official abstract text for this publication.

A wireless power transfer system for selectively disabling a transmit antenna of a plurality of transmit antennas when a foreign object is detected is described. The system comprises a first transmit antenna configured to charge an electric vehicle positioned over a charging region via a first area of the charging region and also comprises a second transmit antenna configured to charge via a second area of the charging region. The system further comprises a controller circuit configured to selectively disable the first transmit antenna when a foreign object is detected in a first space that affects charging via the first area of the charging region. The controller circuit is further configured to selectively maintain activation of the second transmit antenna while the electric vehicle is positioned to receive power from the second transmit antenna via the second area when the foreign object is detected in the first space.
