Charging options forth e high-voltage battery
(mode 2, 3 or 4):
R Charging thro ugh recuperation while the
ve hicle is in motion
R Charging with alternating cur rent when sta‐
tionary:
- Ata mains outlet (mode 2)
- Atawa llbox or charging station (mode 3)
R Charging with direct cur rent when stationary:
- Atafa st charging station (mode 4)
Depending on the count ry-specific vehicle equip‐
ment and your vehicle's charging cable, sin gle
phase ACcharging is also possible.
Obse rveth e dif fere nt grid requirements of your
cur rent location when charging. On lyuse charg‐
ing cables which con form tothe grid require‐
ments. Consult a qualified electrician or your
local grid operator if you ha veany questions.
It is recommended that youch arge the high-volt‐
age battery at a wallbox or charging station due to
the impr ovedch arging per form ance and bet‐
te rch arging ef ficiency of fere d.
Sy stem limits
The po wer output of the high-voltage battery
may be impaired bythefo llowing:
R High or low outside temp eratures
R Elect rical auxilia ryconsumers in theve hicle
being switched on, e.g. operating the air con‐
ditioning sy stem
R Exte nded pe riods without charging
The charging time of the high-voltage battery
may be increased bythefo llowing:
R High or low outside temp eratures
R Exte nded pe riods without charging
R The maximum available charge cur rent of the
ch arging facility
R The settings of thech arging process in the

Atcharging stations with a pre-ins talled

R Visually check thech arging station

to the housing or charging cable. #
Atcharging stations without a pre-
ins talled charging cable:
R For saf etyre asons, on lyuse charg‐

R Never use dama gedch arging

R Do not extend thech arging cable.
R Do not use adap ters. #

The charging cable forth eve hicle must not be
longer than 30 m due tothe legal requ irements
in some countries. This is topreve ntthe inter fer‐
ence of signals being recei vedby radio commu‐

thech arging cable may be routed under‐
ground. If in doubt, ask thech arging station
operator if this is the case before charging the
high-voltage batter y.
