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 aging 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
aging of the high-voltage battery:
R
A high condition 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 aging, please
observe the following recommendations
when handling the high-voltage battery.
Recommendations for handling the high-voltage
battery:
R
Charge the high-voltage battery with direct
current (mode 4) only if necessary.
R
If leaving the vehicle idle for lengthy periods,
park up the vehicle with a high-voltage battery
state of charge between 25% and 30%. Do not
keep the high-voltage battery continuously
connected to power supply equipment.
R
If leaving the vehicle idle for lengthy periods of
time avoid high ambient temperatures if possi-
ble.
R
Check the high-voltage battery's state of
charge every six weeks (/ page 244).
R
Charge the high-voltage battery if the state of
charge is below 15%.
R
Do not disconnect the 12 V battery even if the
vehicle is le idle for a lengthy period. Other-
wise, the condition of the vehicle's high-volt-
age battery cannot be monitored.
R
If the high-voltage battery is used only with
low states of charge, fully charge the high-volt-
age battery every six months.
