Key features to enable NERC PRC-005 compliance and streamline battery maintenance

1. NEMA 4 (IP65) grade protection, so system can be installed in battery room or control room for long term reliable operation
2. String voltage, cell voltage, float current 24/7 monitoring
3. High resolution ohmic measurement (internal resistance/impedance) for each cell
4. Inter-cell connection resistance
5. Ambient and pilot temperature
6. Optional electrolyte monitoring
7. Optional unintentional battery ground detection
8. Plug and play tool to check battery data and set paramaters
9. Ethernet with static IP or DHCP
10. 3G/4G wireless option
11. Access data anywhere with internet (can be restricted within utility private network.)
12. MyBattery platform to handle unlimited sites with secured access
13. Easy integration to existing central management system with data/graph/map.
14. High level reporting for realtime outage and statistics

• Multitude of sites with different battery manufacturers, models, and capacities.
• Load testing is difficult to schedule, time consuming, and costly to perform.
• Existing inspection procedures are often ineffective. Visual inspections, and “snap shot” manual testing cannot reliably identify deteriorated batteries.
• Post seal/corrosion caused failures.
• Manual internal resistance/conductance measurement data is often inconsistent.
• Historical resistance/conductance data is difficult to manage.
• Overwhelming amount of crippling data.
• Existing remote battery monitoring systems are costly, unreliable, and ineffective.

• Your back up power works when needed.
• Battery-related catastrophic failure can be avoided.
• Targeted, knowledge-based maintenance can be scheduled. Deteriorated batteries can be identified before initial site visits to severely limit redundancy.
• Extended battery service life.
• Battery warranty claims can be simplified with complete historical battery data.
• Budgeting becomes easier and more accurate.
• Reduced maintenance and procurement costs.

• Robust hardware design for a long service life – set it and forget it.
• Accurate, high-resolution measurement.
• Automatically captures discharge curve for each cell.
• Easy to install and use.
• Multiple communication methods for battery performance data.
• Easy to integrate to existing central monitoring software.

The only 24/7 BMS built specifically for vented 2V battery room environments.

• NEMA 4 (IP65) grade protection
• Internal resistance/impedance
• Cell-to-cell connection resistance
• Float current, charge/discharge current
• Ambient/ Multiple pilot temperature
• Specific gravity
• Integrated with 6,000 site capacity

1. Select several sites with old and new batteries.
2. Install state-of-health BMS from several vendors.
3. Evaluate all aspects: installation/wiring, field configuration, accuracy, repeatability, discharge capture, actionable data, software and network integration, and technical support.
4. Compare results from each system, including status quo.
5. Set a strategic plan for full scale implementation.
