Abstract
A system and a method for charging of rechargeable batteries is presented. In particular, The charging of battery stacks comprising a plurality of battery cells or storage cells is presented. The system is configured to charge a first subset of storage cells from a storage comprising a serial arrangement of storage cells. The system comprises a driver circuit configured to generate an AC voltage comprising a frequency component at an AC frequency from an electric energy source at a DC voltage. Furthermore, the system comprises a first resonance circuit configured to amplify and/or attenuate the AC voltage as a function of the AC frequency, to yield a modified AC voltage. In addition, the system comprises a first rectifying unit configured to generate a modified DC voltage from the modified AC voltage, and configured to provide electric energy at the modified DC voltage to the first subset of storage cells.
