To Order Call Toll Free: BQMS Battery Monitoring System Common Applications: Power Utilities & Distribution, Data Center UPS Product Description Battery Monitoring Systems The BQMS Battery Monitoring System is designed to measure the aging status of critical backup battery systems by measuring and recording: System voltage, load current, cell voltage, internal/connection resistance, cell temperature and ambient temperature. The BQMS is intended for use on up to 480 vented lead acid (VLA) and valve regulated lead acid (VRLA) battery systems. Installation of the BQMS is non-intrusive and can be completed while the battery system is online. Communication Control Unit (CCU) Standard communication includes Eagle Eye’s Centroid 2 Battery Management Software for recording and trending measured parameters. Centroid 2 can be installed on a private network on multiple PC’s. Networked systems can utilize SMS/Email alerts during alarm conditions. Alternatively, the BQMS can be configured for Modbus output to an existing building management system or SCADA. All BQMS systems have the option to include up to (13) dry contact relays for additional external alarming. Product Features • • • • • • • Comprehensive battery management software for 24/7/365 Battery Monitoring. Installation while systems are online. Meets IEEE and NERC standard recommendations for battery monitoring. Utilizes a patented ripple-removing algorithm to filter noise from measurement results Injects minimal, nonintrusive current for battery measurement Simple to install with custom, pre-assembled installation materials. Add-On Products Include: ELM-Series for electrolyte level monitoring, GFM-100 for ground fault monitoring, and the HGD-2000 for hydrogen gas detection. See the EE-NERC-Series page for more information. BQMS Installation on 125VDC Utility Battery System Battery Management Software • Displays and records string voltage, load current, unit voltage, internal/ connection resistance, unit & ambient temperature Trending analysis of measured parameters on a string and cell/unit level with colored, easy to read graphs PDF and Excel reporting Detailed log of alarm outbreak history Email and SMS alerts Automatically record, save, & playback discharge events Centroid 2 Battery Management Software

BQMS System Composition Typical BMQS systems are configured with the following main components: CCU (Communication Control Unit) A single CCU per system processes all measurement data and handles TCP/IP communication and alarming via dry contacts. Modules Units connected in daisy chain. Wired directly to the battery connections for measurement of cell/unit parameters. Connection Clamps Physical connection to battery system. Installs to battery inter-cell cables or busbars. Server & Client PC Main computer which interfaces with the CCU and runs Centroid Snet Server application. Client PC's installed...
