Description
The battery equalized voltage value can be 2.30–2.40 V/cell, and is 2.35
V/cell by default. The value is configurable in any mode.
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.
