Battery Settings
Battery parameter settings impact battery maintenance, battery lifespan, and UPS
discharge time. When you set battery parameters, note the following:
● Retain default settings for Chg. cur. limiting coef. and Cell float voltage. Only
● When you set parameters, ensure the following: Chg. cur. limiting coef. >
● Single batt. float chg. voltage deviation alarm thres. and Single batt. dis.

Transfer-to-equalized charging cur. coef.
voltage deviation alarm thres. are used to check whether the batteries in
each battery string have the same charge voltage and discharge voltage. When
a value exceeds the specified range, an alarm is generated. The calculation
formula is (Charge/Discharge voltage – Average voltage)/Average voltage x
100%. The charge/discharge voltage and average voltage are obtained from
the BMU. If the BMU is not configured, these two parameters do not need to
be set.
Description
If this parameter is set to
Enable, the float voltage is
calibrated based on the
battery temperature when a
battery temperature sensor is
connected. The parameter is
configurable in any mode.
Calibration coefficient during
float voltage temperature
compensation.
Indicates the reference
temperature during
temperature compensation
of the float charging voltage.
If this parameter is set to
Enable, the UPS
automatically changes the
battery management status
to equalized charge based on
the charge current and float
charge time.
The battery enters equalized
charge state when the
battery current exceeds this
parameter value.
