1. A charging apparatus for charging an energy accumulator of a vehicle via a charging source having a charging plug, the charging apparatus comprising:

  • a charging control device of the vehicle;

    an alternating-current charging device of the vehicle;

    a power switching device of the vehicle,a charging socket of the vehicle, the charging socket comprising seven electrically assignable contacts, whereina first contact is connected as a pilot contact by way of a pilot line with the charging control device,a second contact is connected as a proximity contact by way of a proxy line with the charging control device,a third contact is connected as a protective grounding conductor contact by way of a ground line with vehicle ground,a fourth contact is connected as a neutral conductor contact by way of a neutral line with the alternating-current charging device,a fifth contact is connected as a phase 1 contact by way of a phase 1 line with the alternating-current charging device,a sixth contact is connectable as a positive direct-current contact by way of a DC+ line and by way of the power separating device with the energy accumulator,a seventh contact is connectable as a negative direct-current contact by way of a DC−

    line and by way of the power separating device with the energy accumulator,the DC+ line is connected via a first electric branch line with one of the neutral line or the phase 1 line, andthe DC−

    line is connected by way of a second electric branch line with the other of the neutral line or the phase 1 line.
