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
av ailable from, the high-voltage battery
decreases over the course of its life. Due to
th is, bo th the maximum electrical range that
can be achie vedby theve hicle and its maxi-
mum elect rical output can be impaired.
The following factors could accelerate the age-
ing of the high-voltage batter y:
R frequently fully charging (char gelevel
100%) the high-voltage batter y,especially
when this process is not directly follo wed
by a jou rney
R frequent rapid charging with direct cur rent
(mode 4)
R leaving theve hicle idle for lengt hyperiods
at high ambient temp eratures #
Toavo id accelerated ageing, please
obser vethefo llowing recommendations
when handling the high-voltage batter y. Re
commendations when handling the high-voltage
batter y:
R Every six months, when the outside temp era-
ture is abo ve10 °C, park theve hicle overnight
with a charge leve l below 20%.
R Only charge the high-voltage battery with
direct cur rent (mode 4) if necessar y.
R Char gethe high-voltage battery on average to
a ch arge leve l of 80%. Be yond a charge leve l of
80%, thech arging time is considerably pro-
lon ged.
R If leaving theve hicle idle for lengt hyperiods,
park up theve hicle with a high- voltage battery
ch arge leve l between 30% and 50%. Do not
ke ep the high-voltage battery continuously
connected topowe r supply equipment.
R If leaving theve hicle idle for lengt hyperiods of
time avoid, if possible, high ambient temp era-
tures.
R Check the high-voltage battery's charge level
ev ery six weeks (/ page 180).
R Char gethe high-voltage battery if thech arge
le ve l is below 20%. R
Do not disconnect the 12 V battery even if the
ve hicle is leT idle for a lengt hyperiod. Other-
wise, the condition of theve hicle's high- volt-
age battery cannot be monitored.
Yo u can contribute toreducing theve hicle's
ene rgy consum ption in thefo llowing ways:
R An anticipatory driving style (/ page 154)
R Reduced use of electrical consumers
R Having theve hicle regula rly main tained
The charging time of the high-voltage battery may
ch ange overth e course of its life.
% Depending on the national version, your vehi-
cle is equipped with one of thefo llowing vehi-
cle soc kets.
Yo u can charge the high-voltage battery with
bo th alternating cur rent (mode 2/3) and
direct cur rent (mode 4). 164

Charging stations in European countries are also
equipped with energy supply identi/ers.
You can
re ch arge your vehicle at charging stations where
th ech arging station identi/er cor responds tothe
ve hicle identi/er.

The time take nto charge the battery depends on
th ech arge status of the batter y,the ambient tem-
perature and thech arging capacity of the batter y.The
charging capacit y,in turn, depends on the
supply voltage, the cur rent intensity and the type
of po wer suppl y.
