BMW 3: 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 the
electrical heating are on the convenience charging electronics.

The following simplified wiring diagram shows the high-voltage connections
between the Electrical
Machine Electronics and the other high-voltage components.
