EE-NERC-BMS Battery Monitoring Systems EE-NERC-BMS Cabinet Solution Product Overview An all-in-one battery monitoring solution designed to meet NERC Standard PRC-005-2 - Protection System Maintenance. This standard requires utilities to document and implement programs for the maintenance of all protection systems affecting the reliability of the BES. Battery systems are a critical part of the BES and within Standard PRC-005-2, battery maintenance compliance falls under Table 1-4(f) “Exclusions for Protection System Station DC Supply Monitoring Devices and Systems” with no maximum maintenance interval. This table outlines that “no periodic maintenance” is required if monitoring and alarming occures for the following component attributes: • High and low battery charger voltage • Electrolyte level in every cell • Unintentional DC ground • Float voltage • Battery string continuity • Intercell and/or terminal resistance of the entire battery • Internal ohmic value against relative baseline • Cell/unit internal ohmic value of every cell The EE-NERC-BMS satisfies each of these component attributes by monitoring alarming all of the parameters listed in Table 1-4(f). Electrolyte Level Sensors Installed on VLA Utility Battery Key Benefits • Real-time monitoring eliminates required on-site maintenance activities such as routine manual battery testing. • Included battery management software allows remote monitoring and alarming of all battery systems. Generate reports and view historical measurement data at any time, such as during a NERC audit. • Designed for use in utility environments, the EE-NERC-BMS is available in an industrial enclosure. • Installation can be performed while the system is online, eliminating the need to disconnect battery hardware or use a backup system. • Ripple removing algorithm to filter out noise and produce accurate results. Battery Management Software • Displays and records string voltage, current, cell/unit voltage, internal/connection resistance, cell/unit & ambient temperature • Alarming for all measured parameters as well as electrolyte level, electrolyte temperature, positive & negative grounds • Trending analysis of measured parameters on a string and cell/unit level with colored, easy to read graphs • PDF and Excel reporting • Automatically record, save, & playback discharge events Eagle Eye Power Solutions, LLC www.eepowersolutions.com 1-877-805-3377 info@eepow

EE-NERC-BMSw Battery Monitoring Systems EE-NERC-BMS System Composition BQMS Battery Monitoring System Measures the following parameters: string voltage, string current, cell voltage, cell/connection resistance, cell/unit temperature and ambient temperature. Communicates to server. ELM-Series Electrolyte Level & Temperature Monitor (Optional) Provides per-cell electrolyte level and temperature monitoring. Sensors are attached to each cell by a non-harmful adhesive. In the event of a low level or high temperature alarm, the contact closures on the ELM controller will communicate to the BQMS...
