Battery monitoring systems measure battery parameters and performance in order to provide a warning about battery system failure. That warning becomes a call to action to remedy the identified problems before they translate into an actual failure. If you look at the battery monitoring solutions available today, they measure similar key metrics: battery terminal voltage, ambient temperature, pilot cell temperature, cell or jar level voltages while on float, cell voltage during a discharge event, etc. One of the main ways the these systems differ is on Ohmic measurement, how they measure it and why e.g. conductance, resistance, impedance.

At BTECH, we measure impedance, and we use impedance to predict battery failure. Our system puts an ac disturbance onto the battery system, so that an identifiable current of frequency and magnitude flows and results in an ac voltage drop across the battery cells being measured. Then we filter to extract the signal from the battery system’s electrical noise, and we perform an impedance calculation. That calculation is trended over time and that trend enables our solution to predict battery cell and system performance.

And so for the last 30 years, we have deployed our predictive impedance technology across various applications to solve a real problem: unplanned downtime of mission critical systems due to power loss. BTECH’s solution alerts key personnel about developing problems with their battery system in a sufficient amount of time to allow corrective action to be taken before those problems cause critical shutdowns. Consider what life would be like if you could predict the future…. that’s right, you could foresee challenges and problem areas before they happened to you and you could avoid trouble, danger, uncertainty, etc. That is what we do at BTECH every day. BTECH’s solution not only identifies the problem area, but we identify the specific cell involved. Then, assuming the user initiates corrective action when he/she is first alerted about the future problem, the battery system will always remain in good, working order.

In a day and age when we rely on continuous, uninterrupted power to ensure that our systems, our data, our applications, our networks and our services are available, disruptions in power, no matter how short, result in significant loss: financial, productivity, time, brand value, customer experience, even legal implications.
