BMW 3: Connections
The connections at the Electrical Machine Electronics can be divided into four categories:
- Low-voltage connections
- High-voltage connections
- Connection for potential compensation line
- Connections for coolant lines.

Low-voltage connections
In the low-voltage connector at the Electrical Machine Electronics the
following lines and signals are
combined:
Terminal 30 from the hybrid power distribution box

High-voltage connections
At the Electrical Machine Electronics, there is a total of three high-voltage
connections to connect the
lines for other high-voltage components. The connections for the electric A/C
compressor and
High-voltage cables
The high-voltage cables connect the high-voltage components and are
identified by orange cable
sleeves. The manufacturers of hybrid cars have agreed on a uniform
identification of the high-voltage

Standard charging cable
The standard charging cable is designed for mobile use. All protection and
communication devices
of the standard charging cable are integrated in the so-called "in-cable control
box". The volume and
weight of this solution is low and the charging cable can be easily transported
in the vehicle.

Displays of operating conditions
The hybrid-specific operating states and the state of charge of the
high-voltage battery unit are
displayed in the instrument cluster and, if desired, in the Central Information
Display (CID).
The displays shown below may appear, depending on the driving situation
