Abstract
A battery charging system () for use with an induction charger (). The battery charging system can include a secondary coil () having a plurality of turns for receiving magnetic flux produced by a primary coil () of the induction charger, and a control circuit () for controlling a number of turns of the secondary coil that are used in generating an output voltage for charging a cell (). For example, the secondary coil can include a plurality of taps (), each of the taps providing an electrical connection to the coil at a different point, and thus providing a variety of selectable output voltages.
