Abstract
An inductive power transfer system for charging batteries may include an inductive power transmitter, an inductive power receiver and an electrochemical cell or battery. The inductive power receiver may include a secondary inductor incorporated in enabled batteries or battery packaging, which when inductively coupled to a primary inductor of an inductive transmitter is operable to supply a potential across the electrochemical cell or battery thereby enabling the cell or battery to be charged or maintained at a charged level. The inductive battery may be in the shape of an industry standard battery.
