1. A connection device for a device for charging an electrical energy accumulator (5), comprising:
an input connection (11) having a plurality of phase connections, wherein the input connection (11) is configured to be selectively connected to either a single-phase or a multi-phase electrical power source (3);
an output connection (12) having a plurality of phase connections, wherein the output connection (12) is configured to be connected to a device (4) for charging an electrical energy accumulator (5);
a switching means (2) configured to selectively electrically connect one or more electrical phases (L1, L2, L3) of the input connection (11) to corresponding phase connections of the output connection (12), wherein the switching means (2) includes switching elements configured to couple the one or more electrical phases (L1, L2, L3) of the input connection (11) to corresponding phase connections of the output connection (12) for connecting the device (4) for charging the electrical energy accumulator (5); and
a filter means (1) configured to filter out electrical interfering signals on the electrical connections between the input connection (11) and the output connection (12), wherein the filter means (1) is arranged electrically between the input connection (11) and the switching means (2).
