What Is Ocv Test

Open Circuit Voltage (OCV) is the difference of electrical potential

How is OCV measured?

The Low-current OCV test consists in using a small current to charge and discharge the battery and then measure the output voltage which is approximately equal to OCV . This test have been performed, by the CALCE battery group, for an ambient temperature varying from −10 ◦C to 50 ◦C with interval of 10 ◦C. Fig.

Where is OCV measured?

LIGHTING: Open Circuit Voltage measured across the socket the lamp screws into, with the ballast powered on. It is dangerous to stick a voltmeter into such a socket without precise knowledge of the ballast because exceedingly high voltages could be present.
