I01￿High-voltage￿Components
10.￿REME
• Low-voltage￿connections
• High-voltage￿connections
• Connection￿for￿potential￿compensation￿line
• Connections￿for￿coolant￿lines.
10.3.1.￿Low-voltage￿connections
In￿the￿multipolar￿low-voltage￿connector￿at￿the￿range￿extender￿electrical￿machine￿electronics￿two￿multi-
core￿lines￿with￿the￿following￿signals￿are￿combined:
• Voltage￿supply￿for￿the￿REME￿control￿unit￿(terminal￿30B￿and￿ground￿connection)
• PT-CAN￿2
• Two￿lines￿from￿the￿ACSM￿for￿the￿signal￿for￿the￿quick￿shutdown￿of￿the￿high-voltage￿system￿in
the￿event￿of￿an￿accident￿of￿corresponding￿severity
• Wake-up￿line
• Input￿and￿output￿of￿the￿circuit￿of￿the￿high-voltage￿interlock￿loop￿(REME￿control￿unit￿does￿not
evaluate￿the￿signal)
• Rotor￿position￿sensor￿of￿the￿electrical￿machine￿(supply￿and￿sensor￿signals)
• Signal￿of￿the￿temperature￿sensor￿in￿the￿stator￿coils￿of￿the￿electrical￿machine.
These￿lines￿and￿signals￿have￿relatively￿low￿current￿levels.
10.3.2.￿High-voltage￿connections
Two￿high-voltage￿cables￿are￿connected￿at￿the￿REME:
• 3-phase￿high-voltage￿cable￿from￿the￿range￿extender￿electrical￿machine
• Two-pin￿high-voltage￿cable￿from￿the￿KLE.
