1. An electrical charging system (1) for an energy accumulator (2) of a motor vehicle, the electrical charging system (1) comprising:

  • a supply input (4, 4

    ) in a conductor system having at least one phase conductor (4a) and a neutral line (4b) for energy supply from a power grid,the charging system (1) also comprising a rotating field machine (6) which, via phase windings (u, v, w), being operably connected thereby to a first side of an inverter (3), wherein the inverter is controlled by a control system,a second side of the inverter (3) being operably connected to the energy accumulator (2) to be charged,the phase windings (u, v, w) of the rotating field machine (6) being either selectively isolated or interconnected,a potential line (5b) electrically connecting the neutral line (4b) of the supply input (4) to the inverter (3) via an electrical pathway which bypasses the phase windings (u, v, w), andthe charging system (1) being designed, by at least one isolated phase winding (u, v, w), for one of a step-up connecter charging operation and a step-down charging operation.
