* N N O O TE TE High-voltage battery damage due to
leaving the vehicle idle for lengthy periods
of time
Lithium-ion batteries experience a natural self-
discharge.
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-
#
lowing recommendations when handling
the high-voltage battery.
* N N O O TE TE Accelerated ageing of the high-volt-
age battery
As a result of its basic characteristics, the
storage capacity of and the amount of energy
available from the high-voltage battery
decrease over the course of its life. Due to
y (plug-in this, both the maximum electrical range that
can be achieved by the vehicle and its maxi-
mum electrical output can be impaired.
e battery ery
The following factors could accelerate the age-
ing of the high-voltage battery:
a high level of charge, especially if the
R
vehicle is idle for a lengthy period of time
frequent rapid charging with direct current
R
(mode 4)
leaving the vehicle idle for lengthy periods
R
at high ambient temperatures
To avoid accelerated ageing, please
#
observe the following recommendations
when handling the high-voltage battery.
Recommendations when handling the high-voltage
battery:
Only charge the high-voltage battery with
R
direct current (mode 4) if necessary.
If leaving the vehicle idle for lengthy periods,
R
park up the vehicle with a high-voltage battery
charge level between 25% and 30%. Do not
keep the high-voltage battery continuously
connected to power supply equipment.
If leaving the vehicle idle for lengthy periods of
R
time avoid, if possible, high ambient tempera-
tures.
Check the high-voltage battery's charge level
R
every six weeks ( page 214).
/
Charge the high-voltage battery if the charge
R
level is below 15%.
Do not disconnect the 12 V battery even if the
R
vehicle is le 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
R
(mode 2/3)
Type Combo 1 for charging with alternating
R
current (mode 2/3) and charging with direct
current (mode 4)
Type 2 for charging with alternating current
R
(mode 2/3)
