BDS-Pro Battery Monitoring System

The BDS-Pro Battery Monitoring System is designed to monitor stationary battery systems with up to 24 cells/units. Measured parameters include string voltage, string current, cell voltage, cell/connection resistance, and temperature. The BDS is a robust solution that can be deployed in a wide range of environments. Communication to Eagle Eye’s proprietary battery management software allows for email alerts during alarm outbreak, as well as detailed trending and reporting.

  • 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 BDS-Pro calculate the capacity of the batteries?
No, the BDS-Pro 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 BDS-Pro monitor battery systems in parallel?
No, the BDS-Pro 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 BDS-Pro 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 BDS-Pro. The client can be installed on multiple computers and can pull data directly from the PC with Centroid 2 Server running.

How does the BDS-Pro 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 BDS-Pro 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.

Which parameters are measured in real-time?
String voltage and current are measured in real-time, values are continually updated on the BDS-Pro screen and in the software.

Which parameters are measured on interval and what is that interval?
Cell voltage, cell resistance, and cell temperature are measured on set intervals. These intervals can be set at any time from every 10 min. to once daily. In the event of a discharge these parameters will be measured continually until the discharge has ended.

How long does the system take to measure the resistance of the whole string?
The length of time varies depending on the number of jars. Regardless of the jar quantity, the system takes 3 seconds to measure the jar (actual load duration is 900ms per jar). The measurement cycle on a 60-cell system measuring per jar would take 180 seconds.

Does the BDS-Pro have any dry contact relays?
No, the BDS-Pro 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 BDS-Pro can communicate via TCP/IP to a dedicated PC with Centroid 2 installed. Through the software, Modbus protocol can output from the PC. Each BDS-Pro system requires its own server PC for this solution and is offered as complete kit.

Is the BDS-Pro 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.

Can the BDS measure lithium battery types?
No, currently the system cannot measure any type of lithium battery.

What frequency does the BDS-Pro use during measurement?
270Hz.
