Charging cable for charging at a charg-
ing station or wallbox
;
Charging cable for charging at a mains
socket
Charging cables may differ from the ver-
sions shown depending on the country.
The different versions of charging cables
are distinguished by their charging cable
connectors. The charging cable which is
charged at a mains socket also has controls.
The options listed for charging a high-volt-
age battery are not available in all coun-
tries.
The high-voltage battery can be charged at
a charging station or wallbox in a nominal
voltage range from 100 V to 400 V.
Vehicles with 22 kW on-board charger:
the
high-voltage battery can be charged in a
nominal voltage range from 220 V to 400 V.
i
If possible, only charge the high-volt-
age battery when the charge is below
80%. Charge the high-voltage battery at
the latest when the charge falls below
20%.
Discharged high-voltage battery
The high-voltage electrical system
switches off if the high-voltage battery is
completely discharged. This protects the
high-voltage battery from exhaustive dis-
charge.
i
Switching the ignition on and then off
can reactivate the high-voltage electrical
system temporarily. The vehicle can then
be parked safely.
Do not leave the vehicle with a discharged
or almost fully discharged high-voltage
battery for longer than 14 days. You can
check the charge status in the charge level
Extreme outside temperatures
The efficiency of the high-voltage battery
is temperature-dependent and is signifi-
cantly reduced at low or high temperatures.
In addition, the electrolytes used may
freeze at very low temperatures.
The LED ring in the power output display

Energy consumption and range
The available energy in the high-voltage
battery is basically reduced by the follow-
ing factors:
R
low outside temperatures
R
operating the air-conditioning system or
heating
R
use of electrical consumers
Leaving the vehicle parked for an extended
period at low outdoor temperatures without
charging it can lead to the following:
R
high-voltage battery output is signifi-
cantly reduced
R
charge times can be longer
R
range can be significantly reduced
In extreme cases, it may not be possible to
start the vehicle as a result. You should
therefore always ensure that the high-volt-
age battery is fully charged or that the
charging cable is connected when parking
the vehicle for an extended period of time
at low outside temperatures.
As the high-voltage battery ages, the capa-
city of the high-voltage battery will dimin-
ish over the battery's lifetime. This means
that the maximum range and the maximum
acceleration are reduced.
