Battery Settings
Battery parameter settings are critical to battery maintenance, battery lifespan,
and UPS discharge time. When you set battery parameters, note the following:
● Retain default values for Chg. curr. limiting coef. and Cell float voltage unless
● 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 no BMU is configured, these two parameters do not need to be set.
Description
If this parameter is set to
Enable, the float charging
voltage is calibrated based
on the battery temperature
when a battery temperature
sensor is connected. This
parameter is configurable in
any mode.
Specifies the calibration
coefficient during float
charging voltage
temperature compensation.
Specifies the reference
temperature during float
charging voltage
temperature compensation.
If this parameter is set to
Enable, the UPS
automatically changes the
battery management status
to equalized charging based
on the charge current and
float charging time.
Batteries enter equalized
charging state when the
battery currents exceed this
parameter value.
