MERCEDES-BENZ EQS 2023 Owners Manual

Notes on charging the high-voltage battery at a
rapid charging station (mode 4)&DANGER Risk of fatal injuries due to dam-
aged components
If you use a damaged component to connect
the vehicle to the charging station, this can
result in Nre or an electric shock, for example.
Perform a visual inspection of the charg-
ing station for obvious defects, e.g. dam-
age to the housing or on the charging
cable connection.At charging stations without a pre-instal-
led 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.Do not use a damaged charging cable.Do not use an extension for the charging
cable.Do not use an adapter.Always observe the safety information on
the charging station.&DANGER Risk of fatal injuries when carry-
ing out maintenance work during the
charging process
During the charging process, the high-voltage
on-board electrical system is under high volt-
age.
Do not perform any maintenance work
during the charging process.
Most charging stations must be activated before
the charging process, e.g. using an RFID card or
via Plug-and-Charge. Observe the on-site opera-
tor\bs instructions for the charging station and the notes on Mercedes me Charge (see the vehicle\bs
Digital Operator\bs Manual).
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 consumersthat are switched on. Further information onrecharge ePciency can be obtained at a qualiNed
specialist workshop.
Setting the maximum permissible charging cur-
rent for charging at a mains socket
*NOTE Overloading the mains socket due
to excessive charging current
If the charging current is too high, the fuse
could be tripped or the external mains supply
could overheat.
Ensure that the external mains supply
has been designed to handle the charg-
ing current provided.For safety reasons, only use the charging
cable supplied with the vehicle or an
original Mercedes-Benz charging cable.
Mercedes-Benz thoroughly tests these
original charging cables for their suitabil-Driving and parking209

ity for high-voltage charging of your vehi-
cle.Purchase these parts at a Mercedes-
Benz service center and obtain advice
there.Check the maximum charging current
using the charging capacity shown on
the driver\bs display.
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.
Before charging at a mains socket, have the
maximum permissible charging current for the
relevant mains socket or the building installa-
tion checked by a qualiNed electrician.When charging abroad, observe the country-
speciNc laws.
If you have questions concerning the charging
current or if there is a malfunction, please contact
a qualiNed specialist workshop.

Starting the alternating-current charging process
(mode 2/3)
&DANGER Risk of death when charging at a
damaged socket
The charging process uses high voltage.
If the 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, abrading or driving over the cable.Have a damaged vehicle socket replaced
at a qualiNed specialist workshop as
soon as possible.Never connect the charging cable to a damaged vehicle socket.*NOTE Damage due to overheating of
charging cable and charge port
During the charging process, the charging
cable and charge port can heat up within the permissible limits.
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 charge portbecomes too hot, have the power supply
system checked.*NOTE Damaged or dirty vehicle socket
when the socket Oap is openAlways keep the socket cover and the
socket Oap closed when there is no
charging cable connected. This protects
the vehicle socket from dirt and damage.Make sure that the socket cover is
closed properly before closing the socket
Oap. This can otherwise result in damage
which may prevent the socket Oap from
being opened again.*NOTE Damage to the vehicle socket or the
charging cable connector due to incorrect
handling
Do not use excessive force (maximum 67.4 lbf
(300 N)) to insert the charging cable connec-
tor into the vehicle socket as far as it will go. You may otherwise damage the vehicle socket,

the charging cable connector or their con-
tacts.If you feel there is increased resistance,
pull the charging cable connector out of
the socket and reinsert it.
