6.4.6 Battery
In this menu the battery relevant settings
are done.
Battery count respec
tively available
batteries are set at (5.1). "0"= not
available, "1"= available.
At (5.2) t
he nominal capacity value of the
battery, at (5.3) the number of the
battery cells (cell count) is set.
Furthermore in this section temperature
and
fuse monitoring, asymmetrical as well
as additionell battery relevant settings
are described.
For the analysis of the b
attery asymmetry
the battery tapping point is set at (5.4).
The number of the cells up to the tapped
point is counted from the minus pole (-V
bat
)
of the battery. If the difference of the
measured and calculated asymmetry
voltage value exceeds the value of the set
„Battery unsymm.” (5.5), an event is
generated.
If the tapping point is equal to the half of
the n
umber of cells of the battery, the
calculation according to item a), see the
following page, is done.
Otherwise the missing voltage value +V
bat
which relates to the tapping point is
calculated considering a correction factor
according to item b).
