About the measurement and detection of OCV?

Open circuit voltage (OCV) detection On the production line of lithium battery cells, the measurement of open circuit voltage is one of the important inspections for detecting defective products.

Because the battery has self-discharge characteristics, the open circuit voltage value will gradually decrease accordingly.

If the battery has internal defects, then it will self-discharge more. On the production line, we detect batteries with an open circuit voltage lower than the specified value and reject them as defective.
