MERCEDES-BENZ B-CLASS HATCHBACK 2022 Owners Manual

=
P erform a visual check of the charg-
ing station for obvious faults, such as
massive damage to the housing or
charging cable. 
For charging stations without a preinstal-
led c

harging 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.
= Never use damaged charging cables.
= Do not extend the charging cable.
= Do not use adapters. 
Make sure to observe the safety informa-
tion on t

he charging station. &
DANGER Risk of f
atal injuries when carry-
ing out maintenance work during the
charging process
During the charging process, the high-voltage
on-boar
d electrical system is under high volt-
age. 
Do not perform any maintenance work
dur

ing the charging process. Most charging stations must be activated before
t

he 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 diMerent levels of charging losses and is descri-
bed as recharge ePciency. 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
ePciency can be obt
ained at a qualiNed
specialist workshop. Setting the maximum permissible charging cur-
r

ent for charging at a mains socket *
NOTE Ov
erloading the mains socket due
to excessive charging current If the charging current is too high, the fuse
could be tr
ipped or the external mains supply
could overheat. 
Make sure that the external mains supply
has been designed t

o handle the set
charging current. 
If necessary, reduce the set charging
cur
rent or use a diMerent mains socket. 
For safety reasons, only use the charging
cable supplied wit

h the vehicle or an
original Mercedes-Benz charging cable.
Mercedes-Benz thoroughly tests these
original charging cables for their suitabil-
ity for high-voltage charging of your vehi-
cle. Purchase these parts at a Mercedes- 208
Driving and parking

Benz Service Centre and obtain advice
t
here. 
Check the setting of the maximum
c
harge current using the charging capa-
city shown in the Instrument Display. Before charging at a mains socket, have the maxi-
mum per

missible charging current for the relevant
mains socket or the building inspected by a quali-
Ned electrician. The charging cable supplied is set
to a country-speciNc maximum charging current
value. When charging abroad, the maximum value
may exceed the permitted value for that country.
When abroad, observe the country-speciNc laws
when charging. If you have questions concerning
setting the charging current or if there is a mal-
function, please contact a qualiNed specialist
workshop. 
Set the maximum permissible charging cur-
r

ent in the multimedia system menu
( page 307).
If the exact value of the maximum permissible
c
harging current cannot be set, select the next
smaller adjustable value. %
If the vehicle requires more time than usual to
c

harge the high-voltage battery, check the
maximum charging current settings in the
multimedia system menu. Overview of the charging cable control panel

The vehicle is equipped with an electrical fuse

mains supply. This electrical fuse may trip dur-
ing severe thunderstorms, for example, and
may cause the fuse in the building to trip or
may interrupt the charging process. These
functions protect the vehicle.
Aser the fuse in the building is switched on
again, the charging process resumes automat-
ically. Following an interruption in the power
supply without the fuse in the building being
tripped, it may take up to ten minutes for
charging to resume automatically. Ending the alternating current charging process

DANGER Risk of deat
h when charging at a
damaged socket
The charging process uses high voltage.
If t
he charging cable, the vehicle socket or the
mains socket are damaged, you could receive
an electric shock. 
Only use an undamaged charging cable. 
Avoid mechanical damage such as crush-
ing, abr
ading or driving over the cable. 
Have a damaged vehicle socket replaced
at a q

ualiNed specialist workshop as
soon as possible. 
Never connect the charging cable to a
damag
ed vehicle socket. 216

NOTE Damag e due to overheating of
charging cable and charging cable con-
nector During the charging process, the charging
cable and c
harging cable connector can heat
up within their permissible limit values.
The permissible limit values are inOuenced by
the following factors:
= the power supply system and the charging
cable are not damaged
= the instructions for handling the charging
cable and the control element on the
charging cable have been observed 
If the charging cable or charging cable
connect

or becomes too hot, have the
power supply system checked. *
NOTE Damag
ed or dirty vehicle socket
when the socket Oap is open 
Always keep the socket cover and the
soc

ket Oap closed when there is no charging cable connected. This protects
t
he vehicle socket from dirt and damage. 
Make sure that the socket cover is
closed pr

operly before closing the socket
Oap. This can otherwise result in damage
which may prevent the socket Oap from
being opened again. *
