I01￿High-voltage￿Components
6.￿Charging￿the￿High-voltage￿Battery
described￿in￿the￿previous￿chapter.￿Together￿with￿the￿standard￿AC/DC￿converter￿in￿the￿EME,￿which￿also
provides￿an￿output￿power￿of￿3.7 kW,￿charging￿the￿high-voltage￿battery￿in￿the￿I01￿via￿the￿single-phase
alternating￿current￿at￿7.4 kW￿is￿also￿possible.
In￿this￿version￿of￿the￿convenience￿charging￿electronics￿two￿further￿switch￿contactors￿are￿housed￿which
can￿shift￿through￿the￿direct￿current￿voltage￿of￿a￿DC￿charging￿station￿via￿the￿EME￿to￿the￿high-voltage
battery.￿The￿function￿and￿activation￿of￿the￿switch￿contactors￿are￿described￿in￿the￿previous￿subchapter.
At￿full￿performance￿of￿the￿AC/DC￿converter￿active￿cooling￿is￿required.￿The￿convenience￿charging
electronics￿is￿therefore￿integrated￿in￿the￿cooling￿circuit￿of￿the￿electric￿motor.
