Battery management, User interface and communication

Specification guide

Single UPS, three-phase, 160 to 500 kVA (cont.)

9. Battery management

Batteries are components whose service life is sensitive to operating conditions, i.e. particular care is required for their management. In addition to the protective systems indicated in section 8.4, battery management shall include the systems listed below.

9.1. Self-test

The battery shall be equipped with a self-test that can be run:

ωOn request via a manual control

ωAutomatically according to user-set time intervals.

The self-test shall enable updating of battery parameters and detection of all abnormal conditions in view of preventive maintenance.

9.2. Measurement of actual backup time

The battery function shall be equipped with the means to know at all times the real backup time available (AC power available) or remaining (AC power not available), taking into account the true load on the inverter, the battery temperature and battery ageing.

9.3. Digital battery monitoring

The UPS shall be equipped with a system for battery digital management.

Based on a number of parameters (percent load, temperature, battery type and age), the system shall control the battery charge voltage and continuously calculate:

ωThe true available backup time (section 9.2)

ωThe remaining service life.

9.4. Block by block monitoring

To further optimize battery availability and service life, it shall be possible to equip the UPS with an optional system to continuously monitor all battery strings and display a block by block failure prediction. The system shall include the functions listed below.

ωContinuous measurement of the voltage of each block.

ωContinuous measurement of the internal resistance.

ωIdentification of faulty blocks (trend curves).

ωPossibility of replacing individual blocks.

ωRemoving of all information via Ethernet, dry contacts or JBus.

10.User interface and communication

10.1. User interface

UPS operation shall be facilitated by a user interface comprising:

ωa B&W graphical display

ωON and OFF control buttons (independent of the display)

ωStatus indications with mimic panel.

10.1.1. Graphical display

The mimic diagram shall enable display of installation parameters, configuration, operating status and alarms and indication of operator instructions for switching operations (e.g. bypass). It shall be capable of supervising a single UPS or a parallel system of up to eight UPS units with their SSC (static-switch cabinet).

ωDisplay of measurements

It shall be possible to display the following measurements:

-Inverter output phase-to-phase voltages

-Inverter output currents

-Inverter output frequency

-Voltage across battery terminals

-Battery charge or discharge current

-Rectifier/charger input phase-to-phase voltages

-Rectifier/charger input currents

-crest factor

-Active and apparent power

-Power factor of the load

-Battery temperature

-Battery percent charge

-Available backup time
