For battery impedance measurement, except for measuring the voltage and current with respective sensors according to Ohm's Law, are there any other approaches?
A battery can be considered as a voltage source in series with a resistance (Ohmic or frequency independent). Therefore, finding out the internal resistance of the battery needs to be according to V=RI.
Thank you for your answer that is based on so-called Ohm's low (Z = V/I). But this question focuses on besides this well-known method, are there any other methods that can be used for battery impedance measurement?
