No, it is not advisable to measure the OCV of a battery while it is connected to a circuit. To obtain accurate readings of the OCV, the battery should be disconnected from any external circuits or loads. This ensures that the measurement reflects the true voltage of the battery when no current is flowing through it.
An alternative option, which does not require specific hardware, is analyzing the open-circuit voltage (OCV) curve of batteries. To calculate the OCV, sensors measuring the voltage, current, and temperature of each battery cell are sufficient. These values are already tracked by the battery’s inbuilt battery management system (BMS).
Now, it’s time to measure the OCV of the battery. Follow these steps: Connect the positive (+) probe of the voltmeter to the positive (+) terminal of the battery. Connect the negative (-) probe of the voltmeter to the negative (-) terminal of the battery. Read the voltage displayed on the voltmeter. This reading represents the OCV of the battery.
