1. A source for providing power wirelessly to, or receiving power wireless from, a vehicle, the source comprising:

  • a source resonator capable of generating a first electromagnetic field to provide power wirelessly to a device resonator configured to be mounted to the vehicle, and to receive power wirelessly via a second electromagnetic field generated by the device resonator;

    power and control circuitry coupled to the source resonator and configured to control a direction of flow of the power, including a first direction of flow via the first electromagnetic field during a first time period and a second direction of flow via the second electromagnetic field during a second time period, the power and control circuitry comprising a processor configured to monitor a state of the power and control circuitry corresponding to the direction of flow; and

    a user interface coupled to the power and control circuitry and configured to report information based on the monitored state of the power and control circuitry.
