Structure and inner electrical connection
The battery management electronics (SME) is a bus user on the PT-CAN2.
The rear power distribution box supplies the high-voltage battery unit and the integrated battery management electronics with terminal 30F.
If the safety battery terminal is activated in an accident, the battery management electronics switches the high-voltage electrical system off.
The battery management electronics is connected to the electrical machine electronics (EME) by a high-voltage cable.
For the high-voltage interlock loop, a test lead passes through all connectors of the high-voltage components.
The battery management electronics are connected to the Body Domain Controller (BDC) via the wake-up line (terminal 15 wake-up line).
