Evaluating Battery Run-Down with the N6781A or N6785A 2-Quadrant Source/Measure Unit and the BV9200B Control and Analysis Software
Application Notes
Analyzing and optimizing battery run time requires running battery tests on your battery-powered device, both separately and in combination as a system. Measuring battery run down performance requires long-term accurate current measurement and logging. Traditional approaches to measuring battery drain involve using current transducers falls short of meeting the level of accuracy needed, and battery run down testing can take from hours to days.
Keysight N6780 Series SMUs have advanced sourcing and measuring features that address the challenges and shortcomings of traditional approaches. For the battery rundown test, the N6780 Series SMUs provide a more accuracy battery run down test by eliminates the voltage drop caused by a shunt resistor.
You will also learn how to evaluate battery run down on a mobile device directly powered by its battery using Keysight SMUs and power analyzer mainframe. Download this application note now!
