Charging Apparatus for a Vehicle with Seven Electrical Contacts

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, wherein
• a 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, and
• the DC− line is connected by way of a second electric branch line with the other of the neutral line or the phase 1 line.
