1. A power converter for reduced power consumption balancing and charging of a plurality of cells of a rechargeable multi-cell battery pack, comprising:

  • a primary winding for receiving an input power; and

    a plurality of secondary windings for transforming said input power into a plurality of charging currents to charge said plurality of cells via a plurality of paths, and for balancing said plurality of cells based on said charging currents, wherein a ratio between a first turn number of a first secondary winding of said secondary windings and a second turn number of a second secondary winding of said secondary windings is determined by a nominal voltage ratio between two corresponding cells of said plurality of cells.
