Index Explanation
1 High-voltage�cable�(AC)�from�the�charging�socket
2 High-voltage�cable�(DC)�to�the�electrical�machine�electronics
3 Low-voltage�lines�(for�switching�the�switch�contactors)
4 Coolant�line�(supply)
5 Low-voltage�lines�(signal�connector)
6 High-voltage�cable�(AC)�from�KLE�to�EME
7 KLE�mounting�(potential�compensation�contact)
8 High-voltage�cable�(DC)�from�REME
9 Coolant�line�(return)
10 High-voltage�cable�(DC)�from�the�charging�socket�to�the�KLE
11 Convenience�charging�electronics�(KLE)
With�the�combo�charging�at�7.4 kW�AC�charging�power�the�convenience�charging�electronics�can
convert�both�the�single-phase�AC�voltage�of�the�AC�charging�station�to�direct�current�voltage,�and�shift
through�the�direct�current�voltage�of�the�DC�charging�station�for�the�electrical�machine�electronics
and�high-voltage�battery�using�the�DC�switch�contactors.�The�conversion�of�the�AC�voltage�to�the
direct�current�voltage�required�for�charging�the�high-voltage�battery�is�done�by�the�AC/DC�converter
at�a�maximum�power�of�3.7 kW.�The�properties�and�function�of�the�AC/DC�converter�were�already
