1. A device comprising:
- wireless power receive circuitry to generate power from a received wireless power signal;
a first wireless power transceiver configured to communicate with a second wireless power transceiver included in a wireless power transmission unit using a control channel protocol selected from among a plurality of control channel protocols usable by the first wireless power transceiver;
a processing module coupled to the wireless power receive circuitry and the first wireless power transceiver, the processing module configured to;
transition from an idle state to a first power management state in response to the device being enabled and determining that communication has been established with the wireless power transmission unit; and
transition from an idle state to a second power management state in response to the device being enabled and determining that communication has not been established with the wireless power transmission unit.

Abstract
A battery includes one or more rechargeable cells, a wireless power coil, a battery charger circuit, and may further include an RFID module. The wireless power coil is operable to generate an AC voltage from a wireless power electromagnetic field. The battery charger circuit is operable to generate a battery charge voltage from the AC voltage in accordance with a battery charge control signal and, when enabled, to charge the one or more rechargeable cells via the battery charge voltage. If the battery further includes the RFID module, it is operable to generate the battery charge control signal and communicate with a wireless power transmitter device.
