Using EMSYS WBMS, the reliability of the DC Backup system increases highly

All critical parameters can be continuously monitored which provides better grounds for estimation of batteries’ state of health. There is no need for discontinuous monitoring, there is no need to wait until next periodic maintenance to find bad battery cells. The bad battery cells can be immediately found.

Reduced man power cost for inspection is critical for every customer whether they are small and remote telecom sites or large data center DC backup systems.

Battery replacement can be planned in advance which is very important for further cost reduction. Considerable savings can be achieved by monitoring the batteries, knowing the state they are in and planning the battery replacement based on that data. Not on calendar, but on the performance basis.

EMSYS WBMS also eliminates human measurement errors, especially impedance measurement.

Various reports

The system can generate various report types, many of of which are needed for audit purposes and can be downloaded on demand.

Flexible alarm system

Sensor alarms are generated when any of the measured values go beyond the configured alarm limit or when no measurement is received from the sensor for a preconfigured stale time period.

System integration

It is very easy to integrate EMSYS WBMS with existing automation systems, it supports MODBUS, SNMP and alike.

Warranty claim

With the continuous monitoring, EMSYS WBMS will make sure all warranty replacements are done on time.

Fire risk reduction

EMSYS WBMS monitors both internal battery temperature and ambient temperature and if it detects the temperature increase pattern it will send e-mails, texts to the users and alert them.

Easy access

There is an I-Phone and Android EMSYS application for data viewing on a handheld device or a mobile phone.


EMSYS WBMS as a commissioning and testing tool

Also as a very convenient feature, system can be used as a commissioning tool. During the installation the user or a technician can keep an eye on the EMSYS application and check the battery readings as the monitors go online.

Sometimes, during the commissioning, the customer wants to check the batteries with a discharge test, which can also be performed by EMSYS WBMS. When the UPS goes to a discharge state, everything becomes more dynamic, and at that moment it is important to capture as much data as possible.

Using EMSYS WBMS ensures that all data is collected during the discharge test. It can monitor a discharge test or bank load test in a real time manner and get a report within 10 to 15 seconds.

Key Features

Easy installation
The time spent on installation is usually limited so one of the practical advantages of EMSYS WBMS is that it takes a very short time to install.
Wireless communication
All EMSYS monitors communicate wirelessly with the Gateway. They use IEEE 802.15.4 wireless communication protocol and all of them periodically send the data to the gateway.
INDIVIDUAL BATTERY DC AND AC VOLTAGE, INTERNAL OHMIC VALUE AND TEMPERATURE MEASURING
Each battery has a single monitor attached to it, constantly measuring all important battery parameters and sending the data to the server.
DC Bus DC voltage and AC ripple voltage measuring
Each DC Bus has a monitor attached to it, constantly measuring all important DC Bus parameters and sending the data to the server.
Easy de-installation
Sometimes physical maintenance of the batteries needs to be performed (cleaning the connections, refilling the electrolytes, etc). The technician can take the monitor off the battery in a second, do the maintenance on the battery and hook battery monitor on the bus just as fast, and battery monitor will continue working in the same manner as before.
Current measuring and discharge detection
Both charge and discharge currents are measured by a single high resolution monitor which can distinct between different directions of charge and discharge current.
Web based interface
EMSYS WBMS Web Application can be accessed from any browser (provided that the user has accessing credentials). The user can access the application from any desktop, laptop, handheld device or a mobile phone.
Real time email and SMS alarming
Alarms are information for users that are created when a certain alarming condition is met which usually requires the user’s attention.
Trending of history data
History Readings view allows the user to see the UPS behaviour in a selected period of time. With studying the batteries behaviour in the past, the user can predict its future behaviour.
Bank load test and automatic reports
Web Application can also be used as a Bank Load testing tool. Whether it is a scheduled Discharge test or unscheduled discharge, the user will have a full picture of the events during the discharge.
Automatic and On-demand report generation
Instead of sending the maintenance crew to check batteries the user can schedule a periodic maintenance report. At the chosen date and time the WBMS will generate a report with current readings from the chosen site.
Intelligent thermal runaway detection
EMSYS WBMS detects the Thermal runaway in its early stages. It monitors both internal battery temperature and ambient temperature, and if it detects the temperature increase pattern it will send e-mails, texts to the users and alert them.
Intelligent resistance increase detection
On some ocasions the internal battery resistance increases rapidly in a short time. That signals that the battery has gone bad and needs to be replaced. WBMS will detect that rapid increase in resistance and send e-mails, texts to the users and alert them.
Passive charge balancing
EMSYS WBMS can make sure that every battery of the same string is equally charged.
Flexible system configuration
EMSYS WBMS was designed with different applications in mind. It can be used on small Telecom sites with only a few batteries or it can be used in large Data center UPSs with thousands of batteries.

    Lights go out. Screens go black. Millions invested on power backup systems. Batteries checked on schedule… but the power is out and so is your company.

    What are the chances you will experience this scenario? Chances are much greater than you think, because your backup power system relies on simple yet unpredictable backup batteries in order to operate. Overloaded utilities, anomalies in the power grid, extreme weather conditions and the risk of terrorism are major concerns for business contingence planers.
    Power failures are a fact of life and the key consideration that drives your investment in the first place for mission critical power backup systems. Your quarterly maintenance contract is not adequately protecting you.

    Costs for ensuring reserve battery power for generation station controls, transmis - sion switchgear & substation reclosers was becoming excessive.

    Physical inspections by technicians was expensive and inecient. Approximately 4% of the time the inspectors would nd entire battery strings dead as a result of one battery going bad and causing all other batteriens in the string to fail.
    With weighted labor added, string replacement cost in excess of $15,000 for a 24 battery switch.
    Additionally, batteries could fail in as little as two weeks so the inspections weren’t frequent enough. Lastly, battery service life was restricted to ve years to keep the string failure rate from going higher.

Battery facts

Just one bad battery can cause the entire string to fail. In-warranty batteries in normal use can actually deteriorate in a 2-week time-frame.

20% reduction in storage capacity puts a battery at great risk of failure and should be replaced immediately.
85% of catastrophic UPS failures are caused by batteries.
Approximately 3% of new batteries will fail during the warranty period.
Temperature increase of 18ºC reduces battery life by 50%.

DC backup systems (UPS) are created to ensure an uninterrupted power supply when the input power source fails.

It differs from an auxiliary or emergency power system or standby generator in that that it will provide near-instantaneous protection from input power interruptions by supplying energy stored in batteries.

Batteries (battery strings, battery banks) are the main part and also the most vulnerable part of the UPS. If only one battery goes bad, it can affect the neighbouring batteries, disbalance the charge patterns, generate excessive heat, start a chain reaction that can lead up to a thermal runaway situation.

The whole idea behind battery monitoring systems is to provide up-to-date information about batteries’ state of health so potential problems could be avoided.
