Remote UPS Battery Monitoring
Daily UPS Battery Monitoring for Power Critical Environments
The PowerAgent Battery Monitoring System (BMS) is a remote monitoring system that alerts managers to degradations in the power-producing capacity of batteries in their inside/outside plant uninterruptible power supplies (UPS). Based on advanced patent-pending technology called “admittance” testing, the BMS employs DSP (Digital Signal Processing) and standards-based interface protocols to facilitate seamless integration of battery monitoring into an enterprise-wide network management fabric.
The most flexible, scalable, easily installed and lowest priced system on the market today
Rather than requiring a customized controller and endless sensor wires running the length of a UPS battery string, a sensor sits on top of each battery to provide exact information on a battery basis. These sensors are then daisy-chained together by Ethernet cable to deliver individual battery-specific information to the controller, which in turn shares it with the desired monitoring program.
Manual vs. Sensor-based Testing
Manual battery test methods are often performed a few times per year, if at all. Measurement data is very variable from one site to the next and can be affected by the instrument used, the exact points at which the probes were placed on the battery post, and the skill-level of the technician.
Sensor-based testing provides accurate, consistent and trendable data, which can be analyzed by simple software tools, in order to spot degradation before they become problems, saving time and money.
Digital Signal Processing
Each BMS monitoring sensor has a microprocessor, which implements a couple of very important, patent-pending DSP functions creating digital sinewave synthesis.
Digital sinewave synthesis is a low frequency sinusoidal test signal generated within the battery by stimulating it with a digitally derived pulse-width modulated current source.
The battery’s internal resistance cause this low frequency sinusoidal test current to develop a sinusoidal voltage, which is measured by the sensor’s correlating synchronous detection process.
