It may come as a surprise to some that a control loop’s Bode plot does not always depict the loop stability and that the output impedance measurement, obtained non-invasively, always does. Challengers ...
Specifics on ac resistance and why ACIR has become a standard measurement for Li-ions. The 1-kHz test frequency for ACIR and why it's the benchmark frequency. Comparing ACIR test vs. electrochemical ...
Electrochemical impedance spectroscopy (EIS) is used in this procedure to test the impedance in a commercial battery after connecting it two ways. An analysis of the differences in the obtained values ...
