Battery Health Monitoring
BTECH Predictive Health Systems
- We began providing high tech battery monitoring back in 1993 making us one of the earliest providers of non invasive battery testing. We started with BTECH as the developed and patented their impedance based battery monitoring. Previous to their development of impedance based monitoring there were two methods to verify battery integrity. These were full load testing and individual load testing. For individual systems the Alber method was primarilly used. This method involved putting a heavy 50 or 100 amp load on each battery and watching its perfromance with a piece of test equipment. Full load testing was done by using DC load banks and measuring performance under load. Both of these methods worked but they also degraded the battery each time a test was done. When BTECH developed their method it was the first to allow testing that did not load and degrade batteries. Over the last two decades BTECH has growna and eveolved into the leading technology and company for non-invasive battery testing. The past methods are still valid and used by some but the BTECH method remains the least intrusive and still very accurate. In the early years BTECH's impedance method was decried as no t being meaningful, however for quite some time it has been acknowledged as not only working but being extremely effective for testing.
- A BTECH system wires to each individual battery or cell in a battery string. Through the equipment and wiring the system measures battery voltage, impedance, current, temperature and does analysis of the data gathered to provide historical data, trending and alarming for a very complete weekly health checkup of a battery system.
- We have done many installations throuout North America and continue to use our engineered approach. To learn more about the reporting aspects of the software please visit our paper, An Overview of BTECH Software Reporting.
