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.
Why should a battery pack be monitored?
Therefore the pack current, cell temperature, and each cell voltage should be monitored timely in case of some unusual situations. The battery pack must be protected against all these situations. Good measurement accuracy is always required, especially the cell voltage, pack current, and cell temperature.
