Charging the high-voltage battery (plug-in hybrid vehicles)
152
Never use a damaged charging cable.
R
Do not use:
R
Extension cables
-
Cable drums
-
Multiple sockets
-
Do not use a socket adapter to connect the
R
charging cable to the mains socket. The
only exception is if the adapter has been
tested and approved by the manufacturer
for charging the high-voltage battery in an
electric vehicle.
Always observe the safety notes in the
R
socket adapter's operating instructions.
G
DANGER
Connecting the charging cable to the wallbox
via an incorrectly installed wallbox or adapter,
extension cable or similar could cause a fire or
an electric shock. There is a risk of fatal injury.
To avoid hazardous situations, observe the
following:
Only connect the charging cable to a wall-
R
box that:
is installed correctly and
-
has been approved by an electrical spe-
-
cialist.
For safety reasons, only use charging
R
cables that have been tested and approved
by the manufacturer for charging the high-
voltage battery in an electric vehicle.
Never use damaged charging cables.
R
Do not extend the charging cable.
R
Do not use an adapter.
R
Always observe the safety notes in the wall-
R
box's operating instructions.
The vehicle's high voltage electrical system is
under high voltage.
Do not tamper with the high-voltage com-
R
ponents or the orange cables of the high-
voltage electrical system.
Do not touch high-voltage components or
R
the orange cables of the high-voltage elec-
trical system when a vehicle has been
involved in a crash.
Never touch damaged components or the
R
damaged orange cables of the high-voltage
electrical system.
Do not remove the covers of the high-volt-
R
age electrical system components that are
marked with a warning sticker.
General notes
Method of operation
The vehicle is equipped with a high-voltage
battery for driving. The high-voltage battery
stores the energy needed to operate the elec-
tric motor and releases it again.
The electric motor uses energy that has been
stored in the high-voltage battery when pull-
ing away, accelerating and during the jour-
ney.
In overrun mode, kinetic energy is converted
by means of energy recuperation into electri-
cal energy and stored in the high-voltage bat-
tery.
The high-voltage battery can be charged as
follows:
through energy recuperation while the
R
vehicle is in motion
during the journey using the combustion
R
engine in CHARGE operating mode
with the relevant charging cable at an elec-
R
trical outlet while the vehicle is stationary
with the relevant charging cable at a wall-
R
box while the vehicle is stationary
with the relevant charging cable at a charg-
R
ing station while the vehicle is stationary
The high-voltage battery can be charged in a
nominal voltage range from 100 V to 240 V.
High and low outside temperatures
Low outside temperatures
At very low outside temperatures the maxi-
mum power output of the high-voltage battery
may be reduced. The high-voltage battery is
