Charging the high-voltage battery (plug-in
h ybrid) Notes on charging the high-voltage battery
*
NOTE High-v
oltage battery damage due to
leaving the vehicle idle for lengthy periods
of time Lithium-ion batteries experience a natural self-
disc
harge.
Exhaustive discharging can therefore occur if
the vehicle is idle for several months. This can
damage the high-voltage battery. 
To avoid damage, please observe the fol-
lo

wing recommendations when handling
the high-voltage battery. *
NOTE A
ccelerated ageing of the high-volt-
age battery due to not observing the fol-
lowing recommendations As a result of its basic characteristics, the
s
torage capacity of and the amount of energy
available from the high-voltage battery decrea- ses over the course of its life. Due to this, both
t
he maximum electrical range that can be ach-
ieved by the vehicle and its maximum electri-
cal output can be impaired.
The following factors could accelerate the age-
ing of the high-voltage battery:
= a high level of charge, especially if the
vehicle is idle for a lengthy period of time
= frequent rapid charging with direct current
(mode 4)
= leaving the vehicle idle for lengthy periods
at high ambient temperatures 
To avoid accelerated ageing, please
obser
ve the following recommendations
when handling the high-voltage battery. Recommendations when handling the high-voltage
batt
ery:
= Only charge the high-voltage battery with
direct current (mode 4) if necessary.
= If leaving the vehicle idle for lengthy periods,
park up the vehicle with a high-voltage battery
charge level between 25% and 30%. Do not keep the high-voltage battery continuously
connect
ed to power supply equipment.
= If leaving the vehicle idle for lengthy periods of
time avoid, if possible, high ambient tempera-
tures.
= Check the high-voltage battery's charge level
every six weeks (  page 229).
= Charge the high-voltage battery if the charge
level is below 15%.
= Do not disconnect the 12 V battery even if the
vehicle is les idle for a lengthy period. Other-
wise, the condition of the vehicle's high-volt-
age battery cannot be monitored.
Depending on the equipment and national ver-
sion, your vehicle is equipped with one of the fol-
lowing vehicle sockets:
= Type 1 for charging with alternating current
(mode 2/3)
= Type Combo 1 for charging with alternating
current (mode 2/3) and charging with direct
current (mode 4)
= Type 2 for charging with alternating current

(mode 2, 3 or 4): = Char

ging through recuperation while the vehi-
cle is in motion
= Charging with alternating current when sta-
tionary:
- at a mains socket (mode 2)
- at a wallbox or charging station (mode 3)
= Charging with direct current when stationary
(vehicles with combo vehicle sockets):
- at a rapid charging station (mode 4)
Depending on the country-speciNc vehicle equip-
ment and your vehicle's charging cable, single
phase AC charging is also possible.
Observe the diMerent grid requirements of your
current location when charging. Only use charging
cables which conform to the grid requirements.
Consult a qualiNed electrician or your local grid
operator if you have any questions. Driving and parking
213

It is recommended that you charge the high-volt-
ag e battery at a wallbox or charging station due to
the improved charging performance and better
charging ePciency oMered.
Stowing the charging cable
Always stow the vehicle charging cable in the
charging cable bag provided and secure it in the
boot or load compartment of your vehicle.
Otherwise, the charging cable is not suPciently
secured.
System limits
The power output of the high-voltage battery may
be impaired by the following:
= High or low outside temperatures
= Electrical auxiliary consumers in the vehicle
being switched on, e.g. operating the air con-
ditioning system
= Extended periods without charging
The charging time of the high-voltage battery may
be increased by the following: = High or low outside temperatures
= Extended periods without charging =
The maximum a vailable charge current of the
charging facility

Driving and parking

The charging cable for the vehicle must not be
long er 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.
