6 FAQs about [How to measure a single voltage of a battery pack video]

How do you measure open circuit voltage across a battery pack?

If we assume one terminal of the battery pack is connected to ground, we can measure the open circuit voltage across each cell. This works because DMMs measure differential voltage, or the voltage potential at HI minus the voltage potential at LO.

How do you test a battery pack?

This testing can be a bottleneck in the manufacturing process, so test solutions that reduce time or increase test density are highly desirable. One of the most useful measurements for a battery cell or pack is the open circuit voltage (OCV), but the considerations that must be made at the module or pack level differ from the cell level.

What is a battery pack connected to a DMM to measure OCV?
