• Wake-up�lines�to�the�BDC�control�unit�and�EDME�control�unit
• Control�line�from�the�LIM,�with�which�the�charging�procedure�is�released
• Inputs�and�outputs�of�the�circuit�of�the�high-voltage�interlock�loop�(KLE�control�unit�evaluates
the�signal).
The�KLE�control�unit�is�supplied�with�voltage�via�terminal�30�and�terminal�30B�and�has�two�wake-up
line�outputs.�The�convenience�charging�electronics�can�also�wake�up�the�control�units�in�the�vehicle
electrical�system�when�the�charging�cable�is�connected.
Via�the�bus�system�PT-CAN2�the�KLE�control�unit�receives�the�request�and�the�control�signals
for�charging.�There�is�also�a�line�which�is�wired�directly�from�the�LIM�to�the�convenience�charging
electronics.�Only�when�the�LIM�enables�the�charging�procedure�via�a�signal�on�this�line,�does�the
convenience�charging�electronics�start�the�voltage�conversion�and�thus�the�charging�procedure.
The�high-voltage�connectors�of�the�convenience�charging�electronics�are�also�integrated�in�the�circuit
of�the�high-voltage�interlock�loop.�Via�the�low-voltage�connection�the�test�signal�is�forwarded�to�the
high-voltage�interlock�loop�and�to�the�other�high-voltage�components.�The�KLE�control�unit�monitors
the�test�signal�and�interrupts�the�charging�procedure�if�it�is�not�in�the�specified�range.
High-voltage�connections
There�are�three�high-voltage�connections�at�the�convenience�charging�electronics�to�connect�the
high-voltage�cables�to�the�charging�socket�(1�x)�and�to�the�electrical�machine�electronics�(2�x).�If�the
I01�vehicle�is�equipped�with�a�range�extender,�the�convenience�charging�electronics�has�another�high-
voltage�connection�in�order�to�connect�the�range�extender�electrical�machine�electronics�REME.
