Method and apparatus for equalizing the cell-specific charges of a battery pack comprised of cells (C1 - CN) connected in series, which battery pack comprises bidirectional power converters for transferring charges to/from a cell, which power converters comprise primary circuits and secondary circuits that are galvanically isolated from each other, of which secondary circuits each has its own corresponding cell, to which it is connected, and the primary circuits of which power converters are connected to a common DC circuit (power bus, PB), via which charges can be freely transferred from one power converter to another. |
