Charging the high-voltage battery
78
there must be no foreign objects in the
R
charging cable connector or on the charg-
ing cable socket
keep the charging cable out of the reach of
R
children and animals. Always store the
charging cable in a safe place, e.g. in the
charging cable bag
The high-voltage battery must not be
charged with a damaged charging cable.
Therefore, always make sure that:
you do not damage the charging cable, e.g.
R
by driving over it, pulling too hard or as a
result of heavy impacts
the charging cable is not twisted, as oth-
R
erwise the charging cable may overheat
and the cable covering may be damaged
the charging cable is not placed in water,
R
fluids or snow
The charging cable must always be used in
the correct manner. In order to ensure the
charging cable is handled correctly, observe
the following:
do not make any changes or modifications
R
to the charging cable
only use the charging cable to charge the
R
high-voltage battery
do not pull out the charging cable connec-
R
tor or the charging cable socket during the
charging process
For safety reasons, only use the charging
cable which is supplied with the vehicle or
has been approved by smart for this vehicle.
Useful information
Method of operation
The vehicle is equipped with a high-voltage
battery for driving. The high-voltage bat-
tery stores the energy needed to operate the
electric motor and releases it again.
The electric motor uses energy stored in the
high-voltage battery for pulling away and
accelerating.
In overrun mode, kinetic energy is converted
into electrical energy by recuperation and
stored in the high-voltage battery.
In addition to recuperation, the high-voltage
battery can be charged as follows:
with the suitable charging cable at a mains
R
socket while the vehicle is stationary
with the suitable charging cable at a wall-
R
box while the vehicle is stationary
with the suitable charging cable at a
R
charging station while the vehicle is sta-
tionary

Charging cables may differ from the versions
shown depending on the country.
The different versions of charging cables are
distinguished by their charging cable con-
nectors. Charging cables which are charged
at a mains socket also have controls.
The options listed for charging a high-volt-
age battery are not available in all countries.
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-voltage
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 discharge.
