What to do if the battery open circuit current is small

On production lines that manufacture cells for lithium-ion batteries, OCV testing plays a key role in detecting defects. OCV is a battery’s voltage when it is not connected to any load. Batteries exhibit self-discharge characteristics, which causes their OCV values to decline gradually over time. When a battery has an internal. . Manufacturers carry out the OCV testing in each process after initial charging. Notably during the aging process, OCV should be measured at a constant time interval with high accuracy, to evaluate its small change due to self. .
