## Abstract

Charging apparatus for a vehicle having an energy accumulator, the charging apparatus including a charging source, a charging plug, a charging socket, a charging control device, an alternating-current charging device and a power switching device. The charging socket has nine electrically assignable contacts, the first contact being connected as a pilot contact by way of a pilot line with the charging control device, the second contact being connected as proximity contact by way of a proxy line with the charging control device, the third contact being connected as a protective grounding conductor contact by way of a ground line with the vehicle ground, the fourth contact being connected as a neutral conductor contact by way of a neutral line with the alternating-current charging device, and the fifth contact being connected as a phase 1 contact by way of a phase 1 line with the alternating-current charging device. The eighth contact is connected as a positive direct-current contact by way of a DC+ line and by way of the power switching device with the energy accumulator. The ninth contact is connected as a negative direct-current contact by way of a DC− line and by way of the power switching device with the energy accumulator. The sixth contact is connected as a phase 2 contact by way of a phase 2 line with the DC− line, and the seventh contact is connected as a phase 3 contact by way of a phase 3 line with the DC+ line.
