Notes on charging the high-voltage battery at a
rapid charging station (mode 4)
& DANGER Risk of fatal injuries due to dam-
aged components
If you use a damaged component to connect
the vehicle to the charging station, this can
result in fire or an electric shock, for example.
Perform a visual inspection of the charg-
#
ing station for obvious defects, e.g. dam-
age to the housing or on the charging
cable connection.
At charging stations without a pre-instal-
#
led cable, for safety reasons, only use
charging cables that have been tested
and approved by the manufacturer for
charging the high-voltage battery in an
electric vehicle.
Do not use a damaged charging cable.
#
Do not use an extension for the charging
#
cable.
Do not use an adapter.
#
Always observe the safety information on
#
the charging station.
& DANGER Risk of fatal injuries when carry-
ing out maintenance work during the
charging process
During the charging process, the high-voltage
on-board electrical system is under high volt-
age.
Do not perform any maintenance work
#
during the charging process.
Most charging stations must be activated before
the charging process, e.g. using an RFID card.
Observe the on-site operator's instructions for the
charging station.
The charging cable for the vehicle must not be
longer than 30 m due to the legal requirements in
some countries. This is to prevent the interfer-
ence of signals being received by radio communi-
cation devices in the vehicle or in close proximity
to the charging station. Be aware that parts of the
charging cable may be routed underground. If in
doubt, ask the charging station operator if this is
the case before charging the high-voltage battery.
The amount of energy dispensed for the charging
process, shown by the charging station, may be
higher than the amount of energy actually absor-
bed by the high-voltage battery. This is the result
of different levels of charging losses and is descri-
bed as recharge efficiency. Charging losses occur,
for example, due to heat that builds up when the
vehicle is charging or from auxiliary consumers
that are switched on. Further information on
recharge efficiency can be obtained at a qualified
specialist workshop.
