battery cell impedance measurement
The internal resistance of a battery can be tested in 4 steps: 1) measure the voltage [v_bat] of the battery 2) measure the resistance of an external load. Correlation between different impedance measurement methods for battery cells andreas blidberg degree project in chemical science and engineering. Studying impedance to analyze the li data from eis measurements as different batteries or import impedance data from another battery cell,.
