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.
The system can generate various report types, many of of which are needed for audit purposes and can be downloaded on demand.
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.
It is very easy to integrate EMSYS WBMS with existing automation systems, it supports MODBUS, SNMP and alike.
With the continuous monitoring, EMSYS WBMS will make sure all warranty replacements are done on time.
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.
There is an I-Phone and Android EMSYS application for data viewing on a handheld device or a mobile phone.
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.
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.
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.
