How to Measure OCV of Battery: A Step-by-Step Guide
The open circuit voltage of a lithium-ion battery is determined by measuring the voltage across the positive and negative terminals of the battery when it is not connected to any external circuit. This voltage is a measure of the electrochemical potential difference between the positive and negative electrodes of the battery.
Use the oscilloscope to measure the voltage pulse across the resistor: a 10V pulse means thre battery is delivering 10A current pulses. Note that this method measures using a near short circuit; it is difficult to get much closer to a true short circuit. Method 2. This method measures the internal resistance of the battery without drawing …
