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.
