The high-voltage cables of the charging socket are connected to the convenience charging electronics. Phase L1 and neutral conductor N are designed as shielded high-voltage cables and are terminated with a round high-voltage connector at the alternating current connection of the convenience charging electronics. The pilot line and the line for the charging plug detection (proximity line) are realized as simple signal lines. These signal lines are also shielded and are terminated via a plug adapter at a connector in the convenience charging electronics. The protective earth is connected electrically to ground in close proximity to the charging socket. This way the ground is earthed via the connected EVSE.
On the US version, (Type 1 connector), the connector is locked as long as the vehicle is locked.
The charge status indicator is located at the vehicle charging socket. The lighting of the charge status indicator is provided by an RGB LED, which is controlled by the convenience charging electronics.
The charging socket at the vehicle can only be replaced together with the high-voltage cable as one unit.
