Wireless vehicle charger safety systems and methods use a detection subsystem, a notification subsystem and a management subsystem. The detection subsystem identifies a safety condition. The notification subsystem provides an indication of the safety condition. The management subsystem addresses the safety condition. In particular, undesirable thermal conditions caused by foreign objects between a source resonator and a vehicle resonator are addressed by sensing high temperatures, providing a warning and powering down a vehicle charger, as appropriate for the environment in which the charger is deployed.
