BMS-icom Battery Monitoring System

The BMS-icom Battery Monitoring System is designed to monitor 48V stationary battery systems with up to (4) 12V batteries. Measured parameters include string voltage, string current, cell voltage, cell/connection resistance, and temperature. The BMS-icom is a robust solution that works well for VRLA generator backups and other similar applications. Communication to Eagle Eye’s proprietary battery management software allows for email alerts during alarm outbreak, as well as detailed trending and reporting.

  • True 24/7/365 Battery Monitoring
  • Installation and maintenance can be done while battery systems are online
  • Meets IEEE and NERC standard recommendations for battery monitoring solutions
  • Utilizes a patented ripple-removing algorithm for the most precise and repeated results in any environment
  • Injects a minimal current, allowing the user to test their battery multiple times a day without adverse effects on your battery or battery monitoring system
  • Simple to install with custom (to your batteries and site), pre-assembled installation materials
  • Can monitor all your systems in real time with flexible expanding solutions
  • Can be powered by AC or DC

FAQs

Does the BMS-icom calculate the capacity of the batteries?
No, the BMS-icom does not perform a load test, so there is no way for the system to calculate the capacity. The system does detect and record all discharge events to show how each cell performed during the duration of the test.

Can the BMS-icom monitor battery systems in parallel?
No, the BMS-icom is designed for testing of a single system of up to 24 jars / cells.

How does Eagle Eye’s Centroid 2 software work?
The Centroid 2 software is composed of two parts, the server and the client. Centroid 2 Server is installed on a dedicated PC that must be connected to the same network as the BMS-icom system(s). This software runs in the background on a Windows environment as a service. Centroid Viewer client must also be installed on a PC that is on the same network as the BMS-icom. The client can be installed on multiple computers and can pull data directly from the PC with Centroid 2 Server running.

How does the BMS-icom test jar/cell resistance?
The system injects 400mA to 2A (max.) AC current for a duration of 900ms per jar / cell. During the 900ms duration is (3) 300ms tests. The average of these (3) tests is used as the final test result.

Does the BMS-icom AC measurement signal affect the battery’s condition or lifespan?
The level of AC current applied to the battery by the monitoring system during measurement is insufficient to affect battery life, as it is not continuous nor is it a of a level that could cause the temperature to rise during the short period it is applied.

Does the BMS-icom have any dry contact relays?
No, the BMS-icom does not have a native dry contact relay.

Are there any options for using Eagle Eye’s software in addition to Modbus protocol?
Yes, a single BMS-icom can communicate via TCP/IP to a dedicated PC with Centroid 2 installed. Through the software, Modbus protocol can output from the PC. Each BMS-icom system requires its own server PC for this solution and is offered as complete kit.

Is the BMS-icom hardware rated as explosion proof?
The hardware is not officially rated as explosion proof, however it was designed to be mounted and exposed permanently in a battery room environment. If ex-proof is absolutely required then cabinet solutions are available to meet any specific requirements.
