The EA-BIM 20005 battery impedance meter from Tektronix uses electrochemical impedance spectroscopy (EIS) across 20 channels to characterize Li-Ion battery cells. With industry-standard interfaces and ...
In the previous article in this series, we looked at bridge circuits used to measure impedance. Now, let's look at some more (simple) math. The scaled bridge voltage and current, v vx and v ix ...
All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...
