Description
Transfer-to-equaliz
ed charging cur.
coef. (C10)
The battery enters equalized charge state when the battery current
exceeds this parameter value. The value range is 0.02–0.08, and is
0.05 by default.
SOC to start
equalized charging
(%)
When the SOC is lower than the specified value, batteries enter the
equalized charging mode.
Automatic
equalized charging
When the value is
Enable
, the UPS automatically changes the
battery management status to equalized charging based on the
charge current and float charge time.
Forced equalized
charging protection
time (h)
Enable forced equalized charging when batteries are continuously
under float charging or hibernation. When the forced equalized
charging time reaches the value of this parameter, float charging
starts.
Equalized charging
protection interval
(d)
and
Scheduled
equalized charging
interval (d)
After batteries transfer from equalized charging to float charging, if
the batteries do not discharge, equalized charging starts only after
the float charging time reaches
Equalized charging protection
interval
. After equalized charging is complete, scheduled
equalized charging starts when the non-equalized charging time
exceeds
Scheduled equalized charging interval
.
