Abstract
An inductive charging system transfers energy by inductively coupling a source coil on a power source to a receiver coil for a battery charger. Source current may be received in the battery charger and converted for charging a battery pack. A wireless communication arrangement may also provide for authentication of devices that are allowed by the source to be powered or otherwise charged.
