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.
Among them, the Open Circuit Voltage (OCV) test is a commonly used method to evaluate the performance of lithium batteries. Let’s learn together the principles, related parameters and applications of lithium battery open circuit voltage testing.
Run open circuit voltage (OCV) tests using the example VIs in the Battery Cell Quality Toolkit. The following steps describe an overview of running OCV tests. Verify that the DMM is within the external calibration window to ensure the accuracy of measurements. Perform testing on batteries in a suitable fixture.
To test a battery''s open-circuit voltage, remove the battery if possible or connect to the terminals for testing. Then, set a digital multimeter on DC voltage and measure the reading across the battery terminals. The voltage mentioned on the battery is an open-circuit voltage.
