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

Principles

The SMU02B provides various methods for testing battery states: standard test, AC power

failure test, short test, cyclic test, and planned test. You can use one or more battery test

methods based on the power supply and load power.

50

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.

SMU02B

7.7.2 Battery String Current Imbalance Detection

Principles

If the SMU02B detects that the current difference between battery strings is greater than 30%,

it reports an alarm about battery string current imbalance. This alarm is generated only for the

power system with two or more shunts.

The alarm needs to be cleared manually.

Parameters

No configurable parameters.

7.8 Battery Capacity Calculation

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.

After a power system is powered on, storage batteries are managed in mode C by default to

ensure that storage batteries do not overdischarge at the beginning. After the power system

runs for a period of time, the SMU02B selects an appropriate battery management mode

based on the power grid type.

To limit the output voltage, set the expected maximum output voltage. To limit the output

current, set the current limit. For example, if the expected output current is 20 A and the rated

rectifier current is 50 A, then set the current limit to 40%. (

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.
