Charging the high-voltage battery (plug-in
hybrid)
Notes on charging the high-voltage battery
*
NOTE 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.
* NOTE Accelerated ageing of the high-volt-
age battery due to not observing the fol-
lowing recommendations
As a result of its basic characteristics, the
storage 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
the 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:
R
a high level of charge, especially if the
vehicle is idle for a lengthy period of time
R
frequent rapid charging with direct current
(mode 4)
R
leaving the vehicle idle for lengthy periods
at high ambient temperatures
#
To avoid accelerated ageing, please
observe the following recommendations
when handling the high-voltage battery.
