BMW 3: Charging socket at the vehicle
The charging socket of the G20 PHEV is located on the front left side panel. The charging socket cover is locked and unlocked using an electric motor. This electric motor drive is controlled by the convenience charging electronics. The charging socket cover can be opened only in selector lever position P and with unlocked vehicle central locking system. It can be opened after unlocking by pressing on the charging socket cover.
The charging socket cover and the connector assignment are shown in the following graphic:

- Connection for neutral conductor N
- Connection for phase L1
- Connection for proximity line
- Connection for protective earth (ground)
- Connection for pilot line
- Charging socket cover locking mechanism
- Charging socket cover
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.
