Description
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.
When the SOC is lower than the specified value, batteries
enter the equalized charging mode.
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.
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.
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.
