Abstract
Systems and methods are provided for inductive powering and/or charging of electric or electronic devices or batteries. For example, a system may comprise a base unit, such as a charger or power supply, which includes one or more primary coils generally having a planar or curved surface. Each primary coil can be activated to generate a magnetic field in a direction substantially perpendicular to the planar or curved surface to provide power to one or more inductive power receiver coils of a receiver to power or charge one or more portable devices or batteries. The base unit is capable of detecting a wireless communication signal or a modulation communication signal in the one or more primary coils created by modulation of the receiver's impedance and is capable of using the wireless communication signal or the modulation communication signal to control output voltage, current or power from the receiver.
