I01￿High-voltage￿Components
6.￿Charging￿the￿High-voltage￿Battery
The￿charging￿of￿the￿high-voltage￿battery￿in￿the￿I01￿can￿only￿be￿effected￿if￿the￿potential￿compensation
line￿is￿properly￿connected￿to￿the￿convenience￿charging￿electronics.
Connections￿for￿coolant￿lines
The￿convenience￿charging￿electronics￿is￿integrated￿in￿the￿cooling￿circuit￿of￿the￿electric￿motor.￿This
cooling￿circuit￿is￿described￿in￿detail￿in￿chapter￿11￿"Cooling￿the￿electric￿motor￿components".
6.4.￿Combined￿Charging￿System
The￿"Combined￿Charging￿System",￿or￿combo￿charging￿for￿short,￿is￿a￿charging￿system￿for￿electric
and￿plug-in￿hybrid￿cars￿i.a.w.￿IEC￿62196￿and￿supports￿both￿AC￿charging￿(alternating￿current)￿and
DC￿charging￿(direct￿current).￿A￿Phoenix￿contact￿was￿developed￿in￿cooperation￿with￿the￿automobile
manufacturers￿and￿is￿essentially￿made￿up￿of￿a￿charging￿socket￿on￿the￿vehicle￿side,￿the￿so-called￿inlet,
and￿a￿charging￿plug,￿in￿which￿the￿two￿individual￿charging￿plugs￿are￿integrated￿for￿AC￿and￿DC￿charging.
Thanks￿to￿this￿universal￿connector￿system￿only￿one￿charging￿socket￿is￿required￿at￿the￿vehicle￿in
order￿to￿cover￿the￿various￿charging￿options￿of￿AC￿and￿DC￿charging.￿A￿distinction￿is￿made￿between
connections￿of￿type￿1￿(for￿the￿US￿market)￿and￿type￿2￿(for￿the￿European￿market).￿The￿contacts￿for￿the
DC￿connection￿are￿the￿same￿in￿both￿versions.￿Due￿to￿the￿larger￿DC￿contacts￿in￿comparison￿to￿AC
charging,￿currents￿of￿up￿to￿200￿A￿are￿possible,￿whereby￿Fast￿charging,￿for￿example￿during￿transport,
can￿be￿possible.
In￿the￿I01￿two￿versions￿of￿the￿combo￿charging￿are￿offered,￿depending￿on￿the￿AC￿charging￿power:
• Combo￿charging￿at￿3.7 kW￿AC￿charging￿power￿(standard￿equipment￿in￿Europe)
• Combo￿charging￿at￿7.4 kW￿AC￿charging￿power￿(standard￿equipment￿in￿USA)
In￿US￿market￿vehicles￿option￿4U7￿DC￿Fast￿Charging￿is￿offered￿as￿optional￿equipment;￿this
option￿includes￿the￿necessary￿hardware￿for￿the￿Combo￿charging￿at￿7.4￿kW￿AC￿charging￿or￿DC
charging.
