6 Contact�protection
A�contact�is�available�for�shielding�around�each�of�the�two�electrical�contacts�for�the�high-voltage
cables.�The�shielding�of�the�high-voltage�cable�(shielding�for�each�cable)�is�continued�into�the�housing
of�the�high-voltage�battery�unit�and�thus�contributes�to�the�electromagnetic�compatibility�(EMC).
In�addition,�the�high-voltage�connection�provides�protection�against�contact�with�live�parts.�The
actual�contacts�are�coated�in�plastic�so�that�nobody�can�touch�them�directly.�Only�when�the�cable�is
connected�is�the�coating�pushed�away�and�the�contact�established.�The�plastic�slide�serves�as�the
mechanical�latch�mechanism�of�the�connector.�In�addition,�it�is�also�an�element�of�a�safety�function:�If
the�high-voltage�cable�is�not�connected,�the�slide�conceals�the�connection�for�the�bridge�of�the�high-
voltage�interlock�loop.�Only�when�the�high-voltage�cable�is�properly�connected�and�the�connector
is�locked,�is�this�connection�accessible�and�the�bridge�can�be�inserted.�This�guarantees�that�only
when�a�high-voltage�cable�is�connected�is�the�circuit�of�the�high-voltage�interlock�loop�also�closed.
This�principle�applies�to�all�high-voltage�connections�in�the�I01,�for�instance�connections�at�the�high-
voltage�battery�unit,�at�the�electrical�machine�electronics,�at�the�convenience�charging�electronics
and�at�the�range�extender�electrical�machine�electronics.�The�high-voltage�system�can�only�be�active
when�all�high-voltage�cables�are�connected.�This�is�additional�protection�against�contact�with�contact
surfaces,�which�otherwise�may�carry�voltage.
