About OCV testing when to check?

OCV is the open circuit voltage. OCV detection is mainly to measure the battery characteristics by pressing the probes connected to the voltage tester and internal resistance tester on the positive and negative tabs of the pouch battery. OCV test is an important part of battery testing. .

After the first charge of the battery is completed, each process must be tested for open circuit voltage.

Especially in the aging test, measure the open circuit voltage regularly and check the amount of change.

Since the change in the open circuit voltage value caused by self-discharge is small, it takes at least 100~400 hours for the burn-in test to detect defects.
