Why Battery Monitoring?
The battery is weakest link of any UPS or DC Power System because they degrade in time. The traditional method for detection of weak cells is testing the batteries during a preventative maintenance visit with specialized test equipment. This is a good first step to catching problems that could put your critical load at risk. However, batteries have proven to fail between PM visits even when scheduled quarterly leaving the end-user with a false sense of security. The only solution is to continuously monitor and test your batteries with a permanently installed system that runs 24 hours a day, 365 days a year.

With the BTECH Battery Monitoring System, current and temperatures are being measured thousands of times a day. Voltages are measured up to 24 times a day on each cell, that can mean up to 3/4 of a million measurements. Internal Resistance on each cell is measured every 12 or 24 hours, ensuring no event just slips between the testing cracks. No other system can measure your batteries' important parameters, daily. BTECH Battery Monitoring provides immediate warnings of deterioration and imminent failure of batteries, identifies any individual battery that exhibits problems, and reduces the possibility of damage to the entire battery string.

Why BTECH Battery Monitoring?
The best way to test a battery is to use it. But we don't expect you to be in your battery room the day the power fails in your data center. That's why BTECH does the job for you. BTECH uses Pulsed DC Impedance technology and does not discharge the batteries or create a chemical reaction during the measurement cycle. You can later compare this information with other cells on the system and make your own maintenance plans accordingly.

BTECH Battery Monitoring can also reduce the frequency of your technician visits thereby paying for itself. It would be cost prohibitive to carry out those crucial battery tests once or twice a week. BTECH can scan all battery parameters more than once per day to ensure nothing is missed. In addition, this monitoring system allows battery replacement to be based on the battery’s condition, not simply how long it’s been in use, helping to avoid premature and unnecessary replacement.


BTECH Components

All information collected by BTECH is gathered at the S5 System controller and communicated to the BVM Software Package.  The BVM uses built-in graphing and report generation that provides analysis tools to provide the most effective and comprehensive monitoring package in the industry.

  • Measures Voltage on each cell, either 6 or 24 times per day. The software records data for graphical presentation during THAT day as well as average data for historical analysis or trending. Also compares this data continuously with high and low alarm settings for alarm activation.
  • Measures Internal Resistance on each cell, either 2 or 4 times per day. The software records data for graphical presentation during THAT day as well as average data for historical analysis or trending. Also compares this data continuously with high and low alarm settings for alarm activation.
  • Measures the temperature of either the battery room ambient or a 'pilot' cell. Records this figure for graphing as well as comparison with high and low alarm setting for alarm activation.
  • Measures discharge current from a battery string and compares the data with a discharge alarm limit set in software. In the event of a discharge, rapidly records all cell voltage data as the battery discharges for later identification of weak cells under load.
  • Supplied with dedicated computer running Windows 98/ME/2000/XP software and BTECH proprietary application for reporting, recording and data analysis.
  • The system is modular, so if your needs change, BTECH can be reconfigured or expanded.
  • Low voltage DC components. Measurement components never see greater than 48v nominal DC so battery connections are all low voltage. Electrical isolation is achieved by plastic fiber optic cable.

BTECH Software
BTECH software is an application written to run on Windows XP™ machines supplied as part of a BTECH Battery Monitoring System. It has been carefully designed to be be both easy to use and intuitive, providing just the right amount of information for users who are too busy to read overwhelming reports.

Key features.

  • Informative entry screen, showing all cells on a battery or multiple batteries. "What you need to know"
  • Automatic battery testing under software control.
  • All alarm information readily visible on entry screen.
  • Capability to drill down into battery data, easily from the entry screen via familiar Windows functions.
  • Reports are all visual via graphing functions.

Reports available include:

  • Today's Voltage & Ohmic Value cell data, for any single cell.
  • String data, showing the last reading for the entire battery string.
  • Cell history showing a minimum of 120 days averaged data (if 120 days data is available) for that cell. Other cells may be added for comparison.
  • Battery history, showing history for a particular year of service.
  • Discharge data, graphing the discharge characteristics of the entire battery under discharge following such an event.
  • Programmable alarm limits for Voltage, Ohmic Value, Current, and Temperature.
