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 cables are orange‑colored.
G WARNING
The drive system is subject to high
voltages.
You may be seriously or even fatally injured
if you:
tamper with components or high-voltage
R
cables in the drive system
touch components or high-voltage cables
R
in the drive system on a vehicle which has
been involved in an accident
touch damaged drive system components
R
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 a vehicle 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
through energy recovery while the
R
vehicle is rolling or when braking
Level 1 charging - 110 V / 120 V -
R
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 a dedicated
level 2 charging source. Therefore it is
not recommended as the primary method
of charging.
Level 2 charging - 220 V / 240 V -
R
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 a vehicle
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.
