The￿high-voltage￿cables￿of￿the￿charging￿socket￿are￿connected￿to￿the￿electrical￿machine￿electronics
(via￿the￿KLE￿in￿the￿US￿market).￿Phase L1￿and￿neutral￿conductor N￿are￿designed￿as￿shielded￿high-
voltage￿cables￿and￿end￿with￿a￿flat￿high-voltage￿connector￿at￿the￿alternating￿current￿connection￿of￿the
electrical￿machine￿electronics.￿The￿pilot￿line￿and￿the￿proximity￿line￿are￿simple￿signal￿lines.￿These￿signal
lines￿are￿also￿shielded￿and￿end￿at￿a￿connector￿in￿the￿charging￿interface￿module￿(LIM).￿The￿protective
earth￿is￿connected￿electrically￿to￿ground￿in￿close￿proximity￿to￿the￿charging￿socket.￿This￿ensures￿proper
grounding.
A￿C-shaped￿fiber-optic￿conductor￿runs￿around￿the￿charging￿socket￿at￿the￿vehicle.￿With￿this￿C-shaped
fiber-optic￿conductor￿it￿is￿possible￿to￿show￿the￿status￿for￿charging.￿The￿lighting￿of￿the￿fiber-optic
conductor￿is￿effected￿using￿two￿LEDs￿which￿are￿controlled￿by￿the￿LIM.
The￿charging￿socket￿at￿the￿vehicle￿can￿only￿be￿replaced￿together￿with￿the￿high-voltage￿cable￿as￿one
unit.
6.2.5.￿Charging￿interface￿module￿(LIM)
The￿LIM￿enables￿communication￿between￿the￿vehicle￿and￿charging￿station.￿The￿voltage￿supply￿of￿the
LIM￿control￿unit￿is￿effected￿by￿terminal￿30F.￿There￿is￿a￿terminating￿resistor￿for￿the￿PT-CAN￿in￿the￿LIM.
The￿LIM￿can￿also￿wake￿up￿the￿control￿units￿in￿the￿vehicle￿electrical￿system￿when￿the￿charging￿cable￿is
connected.￿There￿is￿also￿a￿line￿which￿runs￿directly￿from￿the￿LIM￿control￿unit￿to￿the￿electrical￿machine
electronics.￿Only￿when￿the￿LIM￿control￿unit￿enables￿the￿charging￿procedure￿via￿a￿signal￿on￿this￿line,
does￿the￿electrical￿machine￿electronics￿start￿the￿voltage￿conversion￿and￿thus￿the￿charging￿procedure.
