Monitoring System

Battery Monitoring System (BMS)

An Uninterruptible Power Supply (UPS) is only ever as good as its battery bank, and there any many ways batteries can be rendered ineffective. Age, temperature, and incorrect charging can slash cell capacity. Terminals can work loose over time causing high resistance. Operator error or spurious trips can leave your battery isolated without you even knowing about it. Our Battery Monitoring System (BMS) is the safety net your batteries need. The condition of each cell and the string as a whole is logged, highlighting any issues as soon as they develop, so they can be rectified before they cost you money.

The BMS is compatible with any battery. Optically-isolated probes are attached to each battery block and linked back to the central control board. Mechanically and electrically robust and engineered for safety above all, this design virtually eliminates alarm errors from probe faults. Each control board can monitor up to 256 cells, with expansion boards added to accommodate even larger batteries. Batteries are never cheap, and an over-charged or deep-discharged string is an avoidable expense. A battery that didn’t perform can impact on your operations, with serious financial consequences.


Batteries need to be taken care of, as they provide power to their specific systems. However, we’re sometimes unaware that our ways are incorrect and can damage or harm not just the life-span of our battery but the output of it. That is why a proper way of charging is needed. In this case, before the battery gets isolated without you knowing it, there’s our battery monitoring system that can help you avoid those scenarios.

Our Battery Monitoring System will serve as a feed for your battery needs. As soon as they form, each cell’s state and the string as a whole are logged, highlighting any problems, so they can be rectified. Its design life estimate is focused on maintaining the battery in compliance with recommended procedures, working under optimal conditions, and ensuring that any individual failing units are replaced before the other units in the string are affected.

What makes the BMS highly attractive is the Optically-isolated probes attached to each battery block and linked back to the central control board by RJ45 cable. Aside from that, each control board can monitor up to 256 cells, with expansion boards added to accommodate larger batteries. This way of designing the system basically eliminates error alarm errors from probe units and ensures safety above all.

Putting customer satisfaction in high regard, each BMS is tailor-made to the specifications needed by each client. As a means of monitoring and gathering data from the BMS, there are three ways in which the system can be monitored:

  • Standalone – There’s no display or remote link. Your engineers periodically connect a laptop to download status information and logged data. Ideal for normally unmanned sites.

  • Local Com – A mimic panel or touch-screen display is provided for at-a-glance status indication. The BMS can also generate alarms on the battery charger.

  • Remote Com – Comprehensive real-time measurement and integration with your SCADA system through ethernet, CANBUS or MODBUS for ultimate vigilance and protection.
