- How does Battery Management System work?
With the Alpais battery management system, a battery module is installed in each battery. The
battery module measures the voltage, temperature, and internal resistance of each battery. Charge
and discharge status, string current, and string voltage are measured by each string module placed
on each string. Ambient humidity and temperature are also measured by the sensors in these string
modules. The control module collects and records the data received through the communication
links between them. Afterwards, the data is transmitted to the user with the Alpais software to show
the battery status as well as time-axis or column graphs. Notifications of critical and alert batteries
are sent by e-mail and SMS and displayed via the interface. In this way, critical batteries are detected
and necessary actions or planned battery changes can be made according to the data received.
- I have a periodic maintenance agreement with my UPS or battery service provider. Why do
I need a Battery Management System?
Your periodic maintenance cannot keep you as safe and secure as you think. Batteries and
management of batteries are shown as the cause of nearly 85% of interruptions connected to the
uninterruptible power supply. Periodic maintenance has become a traditional method as a result of
time. However, there are still interruptions in critical area applications, and these have considerable
costs to business owners. Therefore, protecting your backup power system with only periodical
maintenance will not reduce the 85% failure rate caused by the battery and will not reduce your risks
sufficiently. Batteries, which are unpredictable by nature, can suddenly break down within 2 weeks
and cause your system to crash.
-I already have a monitoring system in the UPS or Rectifier. Is the Battery Management
System necessary for my operation?
All monitoring systems are not the same. Monitoring systems in UPS or Rectifiers monitor batteries
as a group and provide only string-based monitoring. It monitors the battery pack as a whole, as a
block. They usually monitor the group's voltage and charge/discharge states, which cannot provide
adequate protection. However, each battery in the battery group has separate importance; if even
one battery in the group fails, the system will not operate or if one battery is unhealthy, this will
affect the whole group. In other words, since the monitoring systems in the UPS or Reducer are not
able to inspect each battery individually, your system is still at great risk, even when everything
seems ok. Whenever you need to ensure that your system will work properly, it is essential to use a
system that can monitors each battery separately, examine parameters that may affect its health,
and allow you to perform a scheduled battery replacement.
- Instead of installing a Battery Management System, I can reserve some more resources and
replace all my batteries. Should I still use a Battery Management System?
The backup power system responsible makes this mistake. Installing a new battery system does not
eliminate the risk of battery failure. Risks cannot be reduced to zero in any unmonitorable
component. The possibility of fabricated problems and the effect of this situation on the total life of
the system and the fact that some batteries can be completed by the end of the warranty period
(approximately 3%) are among the risk factors that cannot be ignored. Even if your batteries are
newly purchased, unexpected situations may occur and even your new system that has been relied
upon can interrupt your business and cause financial losses. Thanks to the measurements and
reports provided by the battery management system, it is possible to identify production-related
problems and submit reports for warranty evaluation.
- Installing the Battery Management System is a cost for my business. Will it benefit
financially?
Contrary to popular belief, the battery management system has many financial benefits. Reduces
routine visits or maintenance to battery rooms and reduces the amount of work done, saving you
money. It may reduce the frequency of discharge tests that wear batteries; you save time, the life of
your batteries, and cost. Because you can monitor the status of your batteries instantly and be aware
of the alarms and warning situations as soon as possible; so you can prevent situations that reduce
the life of your batteries individually by detecting and replacing an unhealthy battery and reducing
the life of the entire system. Thus, the life of your battery system is extended, its continuity is
ensured and replacement of the whole battery group is postponed. Even with this situation, the
battery management system is a self-paying system.
