High-voltage battery
Introduction
The components of the drive system are
indicated by yellow warning labels to make
you aware of high voltage.
High‑voltage cablesa
re orange‑colored.G
WARNING
The drive system is subject to high
voltages.
You may be seriously or even fatally injured
if you:
R tamper with components or high-voltage
cables in the drive system
R touch components or high-voltage cables
in the drive system on avehicle which has
been involved in an accident
R touch damaged drive system components
Do not remove any drive system component
covers which are marked with a warning
sticker. Do not tamper with components or
orange high-voltage drive system cables. G
WARNING
The high‑voltage battery of the drive
system is located under the vehicle’s
underbody. When the pressure inside the
high‑voltage battery exceeds a certain
value, for example in case of avehicle fire,
inflammable gas will escape via a duct. The
inflammable gas escapes to an area under
the vehicle. This prevents the high‑voltage
battery from exploding.
Stay away from this area of the vehicle. The drive system is powered by a
high‑voltage battery. The high‑voltage
battery stores and releases the energy
required for operation of the electric
motor.
The electric motor uses the energy that is
stored in the high‑voltage battery when
driving off and when accelerating.
When rolling, kinetic energy is converted
into electrical energy by energy recovery
and stored in the high‑voltage battery.
The range of the vehicle is reduced when
consumers are switched on, e.g. climate
control.
The high‑voltage battery can be charged in
a voltage range from 100 V to 240 V.
The high‑voltage battery can be charged
R through energy recovery while the
vehicle is rolling or when braking
R Level 1 charging - 110 V / 120 V -
A travel cord will be supplied with the
vehicle. This charging cable can be
plugged into commonly available
110 V / 120 V, 15 A power sources. This
charging method will take longer to
charge your vehicle than adedicated
level 2 charging source. Therefore it is
not recommended as the primary method
of charging.
R Level 2 charging - 220 V / 240 V -
For the fastest possible charging time, a
dedicated 220 V /240 V, 20 A circuit is
required. Local electrical code can vary
from town to town. Therefore, it is highly
recommended that this service is
professionally installed. This service
should be installed in a dry area with
easy access to the passenger side of the
vehicle. You will need to obtain avehicle
charge connector that can be wired
directly to or plugged into the dedicated
220 V / 240 V service. Charge connectors
will be available for purchase through
your authorized electric drive smart
center.

High-voltage battery>> Operation.
Use only charging cables which have been
approved and recommended for the vehicle.
Do not use:
R extension chords
R cable reels
R multiple sockets
R travel adapters
i When possible, only charge the
high‑voltage battery when the charge
level is below 80 %.
It is recommended to charge the
high‑voltage battery prior to reaching
less than 20% state of charge.
Discharged high‑voltage battery When the high‑voltage battery is
completely discharged, the drive system is
switched off. This protects the battery
from exhaustive discharge.
i By switching the ignition off and on
again, the drive system can be briefly
reactivate donce. This allows you to park
the vehicle safely.
Do not allow your vehicle to remain
stationary for more than 14 days with a
discharged, or nearly discharged,
high‑voltage battery. You can check the
charge level with the charge level gauge
(Y page 79).
High or low outside temperatures The efficiency of the high‑voltage battery
is temperature-dependent and decreases
at high or low temperatures .Additionally,
the electrolytes used can gel at very low
temperatures.
You can check the maximum capacity
available using the indicator in the
multifunction display (Y page 83).Energy consumption and range The available energy of the high‑voltage
battery is reduced by:
R
low outside temperatures
R switching on electrical consumers
At low temperatures and after being parked
for an extended period without charging,
the physical properties of the
high‑voltage battery:
R can cause a significant reductio ninthe
performance of the battery
R can lead to longer charging times
In extreme cases, you will not be able to
start the vehicle. For this reason, always
connect the charging cable or make sure the
battery is completely charged when
parking the vehicle in low outside
temperatures or for an extended period of
time.
Due to its physical properties, the
capacity of a high‑voltage battery
decreases over its lifespan.
Thus, the following are reduced:
R the maximum attainable range of the
vehicle
R the maximum performance output
(acceleration) of the vehicle
You can actively contribute to the
reduction of the vehicle's energy
consumption by:
R driving conservatively
R maintaining the vehicle regularly
R decreasing the use of electrical
consumers
Notes on battery care Avoid storing and transporting the vehicle
at high temperatures for extended periods
of time (e. g. container transport).
When out of use for longer periods of time,
connect the vehicle to a voltage supply.
If the vehicle is not connected to
avoltage
supply, it must remain within a High-voltage battery

"Vehicle Homepage". For this reason, make
sure than no unauthorized persons have
access to your personal area.
After selling the vehicle, you are required
to delete the vehicle from your personal
area on the "Vehicle Homepage". You must
also destroy the vehicle verification code
(VVC) documents.
If you have bought a pre-owned vehicle, it
may be possible that the previous owner
still has access to the "Vehicle Homepage".
For this reason, have a new vehicle
verification code (VVC) reissued to you at
an authorized electric drive smart center
after purchase. With this new code you can
set up the access to your vehicle as
described in the "Personal area setup"
section. Here you can also deactivate the
previous owner's access ,should it still be
active.
Calling up the functions of the "Vehicle
Homepage" If the vehicle is registered in your
personal area of the "Vehicle Homepage",
you can, for example, access the following
functions:
R call up the current charge level
R program the departure time
R activate the "Air conditioning before
start" function
When the vehicle is being charged, you can
call up the estimated charging time and the
attainable range. Both results are
estimated values because, for example,
they are influenced by the following
factors:
R outside temperature
R active electrical consumers, e.g. air
conditioning, lights
R personal driving style
R traffic conditions
Plan for a sufficient reserve accordingly. Connecting the vehicle to the Internet
via powerline If you wish to use the "Vehicle Homepage"
at home, your vehicle must be able to access
the Internet
.This is possible via your DSL
router, for example. This connection is
established by means of the inserted
charging cable using powerline
technology.
The vehicle supports powerline
communicatio naccording to the "HomePlug
AV" standard. Data is transmitted via phase
L1 and the neutral conductor of the power
line.
In order for the vehicle to access the
Internet, you require a commercially
available adapter of the "HomePlug AV"
standard. This adapter must also have an
encryption button so that it can be
configured to communicate with the
vehicle. Connect the adapter to the power
supply as well as your Internet connection.
If the adapter is connected to different
phase than L1, a phase coupler must be
additionally installed. Only in this way
can stable communication be guaranteed.
For questions, consult a qualified
electrician.
i If you already have a powerline network
installed, the vehicle can be integrated
into it.
To establish a connection between the
vehicle and a powerline adapter, carry out
the following:
X Connect the vehicle to a power socket or
a wallbox.
The right 0004indicator lamp on the
vehicle socket must flash green.
X Insert the powerline adapter into a
neighboring power socket. Observe that
the vehicle and the adapter are
connected via phase L1.
X Switch on the ignition.
X Call up the Charge current menu on the
control system (Y page 88). High-voltage battery
