How to Measure Battery Internal Resistance Using the Current Interrupt ...
The Current Interrupt Method To understand how to use the current interrupt method to measure the real part of the complex impedance, refer back to the Randles circuit model in Figure 1. In the model, the geometrical inductance of the cell and the test instrumentation interconnects are shown along with the electrode parameters previously discussed.
Components and Methods for Current Measurement
The resistor is a direct method of current measurement that ha s the benefit of simplicity and linearity. The current sense resi stor is placed in line with the current being measured and the resultant current flow causes a small amount of power to be converted into heat. This power conversion is what provides the voltage signal.
Battery SOC: How Do We Estimate "State Of Charge" Of Batteries…
All these methods rely on measuring a convenient parameter that changes as the battery is charged/discharged. (Photo Credit : Bloomua / Shutterstock) However, all these methods have their own shortcomings, and therefore cannot be relied upon to provide 100% accurate readings of the ''remaining charge'' in the battery.
