7 VRLA Battery Management 7.1 Battery Charging And
DischargingIf the AC input to the power system is normal and meets load
requirements, the rectifierssupply DC power to loads and VRLA batteries. If the AC input to
the power system isabnormal, VRLA batteries supply power to loads. After the AC
input is restored, rectifierssupply DC power to loads and VRLA batteries.
7.1.1 Float Charging
Principles
VRLA batteries self-discharge slowly when they are in use. To
compensate for the resultinglosses, charge VRLA batteries in float mode to ensure they are
fully charged. Float chargingalso helps maintain battery capacity after a large amount of
electricity is discharged.Parameters
Table 7-1 Float charging parameter description
Parameters Description Default Value Value Range
Float Charge(V) The voltage at which
VRLA batteries are
charged in float mode.
NOTE
The float voltage must be
lower than or equal to the
boost charging voltage.
53.5 42.058.3
7.1.2 Equalized Charging
Principles
After long-time float charging, lead-acid batteries suffer great
loss caused by self-dischargeand their activity deteriorates. Equalized charging helps to
rapidly restore battery capacity -

7.1.4 Scheduled Equalized Charging
Principles
If the power grid is of high quality and without AC power
failures for a long time, lead-acidbatteries have low activity because they are always in the float
charging state. To improvebattery activity, you can charge lead-acid batteries in
scheduled equalized mode by settingcharge intervals.
Since no AC power failures occur for a long time, lead-acid
batteries are charged in floatmode with a small current. Therefore, the change from scheduled
equalized charging to floatcharging depends on the charging duration rather than the
battery current.Parameters

7.3 Standard Battery Test
The SMU02B provides the following methods for standard battery
test states: AC powerfailure test, cyclic test, planned test and manual test. You can
use one or more of thesemethods based on power supply and load .
Table 7-7 Test method description
Test Method Description
AC power failure test Starts a battery discharge test during an
AC power failure.Cyclic test Starts a standard test periodically.
NOTE
A cyclic test and planned test cannot be performed
simultaneously.Planned test Starts a standard test at a preset time.
NOTE
A cyclic test and planned test cannot be performed
simultaneously.Manual test Manually starts a battery discharge test.
During any battery test, the battery discharge current depends
on the load current. In allbattery tests except for the AC power failure test, set the
rectifier output voltage to 1 V belowthe test end voltage to ensure that all load currents are from
VRLA batteries.7.3.1 Starting a Test
Description
A battery test can start automatically or manually.
Automatic startup: After parameters are configured, the battery
test starts automaticallywhen the conditions are met.
Manual startup: After you manually start a battery test on the
LCD or WebUI, the powersystem tests batteries immediately.

7 VRLA Battery Management
7.1 Battery Charging If the AC input to the power system is normal and meet load requirements, rectifiers supply
DC power to loads and VRLA batteries. If the AC input to the power system is abnormal or
rectifiers cannot supply DC power, VRLA batteries supply power to loads. After the AC input
is restored, rectifiers supply DC power to loads and VRLA batteries.
7.1.1 Float Charging
Principles
VRLA batteries self-discharge slowly when they are being used. To compensate for the loss
caused by self-discharge, charge VRLA batteries in float mode to ensure their full amount of
electricity. Float charging also helps to maintain battery capacity after a large amount of
electricity is discharged.

7.1.2 Boost Charging Overview
Principles
After long-time float charging, VRLA batteries suffer great loss caused by self-discharge and
their activity deteriorates. Boost charging helps to rapidly restore battery capacity after the AC
power supply is restored and helps to maintain battery activity and capacity. The boost
charging voltage is higher than the float voltage.
Table 7-2 describes the boost charging modes supported by the SMU02B.

7.1.3 Automatic Boost Charging
Principles
The SMU02B determines whether the current battery capacity is sufficient based on the
charge current and remaining amount of electricity. If the conditions for Boost charging are
met, Boost charging is triggered automatically after the AC power supply is restored. After
VRLA batteries are fully charged, float charging is triggered automatically.

7.1.4 Cyclic Boost Charging
Principles
If the power grid is of high quality and without AC power failures for a long time, VRLA
batteries have low activity because they are always in the float charging state. To improve
battery activity, you can charge VRLA batteries in Cyclic Boost mode by setting charge
intervals.
Since no AC power failures occur for a long time, VRLA batteries are charged in float mode
with a small current. Therefore, the change from cyclic boost charging to float charging
depends on the charging duration rather than the battery current.

7.1.5 Pre-boost Charging
Principles
To ensure the accuracy of battery discharge test data, perform a pre-boost charging for VRLA
batteries based on the battery capacity before a cyclic or planned discharge test starts.
Pre-boost charging is considered as one specific scenario of cyclic boost charging, and
changes to float charging after the preset charging duration ends.

7.2 Battery Current Limiting
Principles
To prevent battery bulges caused by overcurrent during battery charging, battery currents
should be limited to a constant value. If the charge current exceeds the threshold, an
overcurrent alarm is generated.
If you need to charge storage batteries quickly, change the value of Current Limit. A greater
value indicates a higher battery charging speed.The upper limit of the value is 0.25 C10

Control Mode
Test Method Description
Short test Starts a short-term battery discharge test periodically. The
default test duration is 5 minutes.
Cyclic test Starts a standard test periodically.
Planned test Starts a standard test at a preset time.
In any battery tests, the battery discharge current depends on the load current. In all battery
tests except the AC power failure test, set the rectifier output voltage 1 V below the test end
voltage to ensure that all load currents are from VRLA batteries.
If the battery temperature is lower than the minimum value, stop all ongoing battery tests and
do not start any new battery test.
The standard test, AC power failure test, cyclic test, and planned test stop automatically
immediately when any test end condition is met, namely, when the test end voltage, test end
capacity, test end temperature, or battery test time arrives.

7.4 Battery Temperature Compensation
Principles
To prolong the battery lifespan, battery charge voltages should be adjusted based on battery
temperatures during float charging or hibernation.Temperature correction equation for the
float and hibernation voltages is as follows: V = V0 – (T – T0) x ρ
Where
V: Float charging or hibernation voltage after temperature compensation
V0: Float and hibernation voltages at the most appropriate temperature
T: Battery temperature measured by a battery temperature sensor
T0 : The most appropriate temperature configured by users
ρ : Temperature compensation coefficient is user-defined
If the battery temperature is in the range of 5°C to 45°C, temperature compensation is
triggered. If the battery temperature is below 5°C, set T to 5. If the battery temperature is
above 45°C, set T to 45.
The temperature compensation correction value (δ V = V – V0) is within the range of –2 V to
+2 V. If the actual δ V is beyond the range, the value of V0 (tolerance ±2 V) prevails.

7.6 Low Voltage Disconnection Protection
Principles
If an AC input is abnormal, VRLA batteries start to power loads. In this case, the SMU02B
drives contactors to disconnect loads based on preset disconnection parameters. After the AC
input becomes normal, the rectifiers begin to power loads.
The SMU02B supports two-level disconnection (BLVD, LLVD) or three-level disconnection
(BLVD, LLVD1, and LLVD2), based on different power system type. The SMU02B
disconnects secondary loads and then primary loads, helping to prolong the backup time for
primary loads.
The maximum disconnection mode for power system type is three-level disconnection (BLVD,
LLVD1, and LLVD2). Please refer to Power System User Mannal for actual disconnection
mode. This manual takes the three-level disconnection as an example.

7.7 Battery Imbalance Detection
7.7.1 Middle Voltage Detection for a Battery String
Principles
To check battery balance, detect the voltage at the middle point of a battery string during
battery discharge.
If the absolute value of VB-2 xVn is greater than or equal to 2.0 V for 30 seconds, a battery
imbalance alarm is generated. In this formula, VB is the voltage at either end of a battery
string and Vn is the voltage at the middle point of battery string n. The SMU02B detects the
middle point voltages of a maximum of six battery strings respectively.
After the absolute value of VB-2 xVn drops below 2.0 V, the alarm is cleared automatically.

7.9 Intelligent Battery Hibernation
Principles
A storage battery is fully charged in most cases, and the float charging capacity is much
greater than the battery self-discharge capacity. This shortens the battery lifespan because
surplus electricity is consumed in the corrosion of positive grids and drying of electrolyte. To
prolong a battery lifespan, enable the intelligent battery hibernation function when charging
storage batteries in float mode.
If no mains outage occurs during a long time, charging storage batteries with a small voltage
lower than the float voltage also helps to increase a battery lifespan.
The SMU02B determines a power grid type based on the total duration for mains failures
within 15 consecutive days and then enables an appropriate battery charge management mode
to extend a battery lifespan.

8.3 Rectifier Overvoltage Protection (Optional)
Principles
A rectifier is protected if the output voltage is greater than the maximum value.
If a rectifier experiences overvoltage due to an internal fault, the rectifier shuts down and
then restarts. If the rectifier experiences three consecutive times of overvoltage due to an
internal fault within 5 minutes, the rectifier latches off.
If the busbar voltage exceeds 63 V due to an external fault, and the overvoltage condition
lasts for more than 500 ms, the rectifier latches off.
The SMU02B generates a rectifier protection alarm.
This function applies only to CAN-type rectifiers.

9.1 Intelligent Rectifier Hibernation
Principles
The rectifier efficiency increases in proportion to the load power. If the total load power is low,
certain rectifiers can be hibernated to improve the load power of running rectifiers and
increase the rectifier efficiency. This facilitates energy conversation.
Rectifiers should be hibernated in turn to ensure the same aging degree. If the difference
between the longest rectifier running duration and the shortest rectifier running duration
exceeds the value of Cycle Period, keep all rectifiers running for 2 hours and then hibernate
certain rectifiers.
