The AC Impedance and DCIR both indicate battery''s power characteristics while DCIR is more popularly used by battery manufacturers since the test is simple and the results are reliable. According to IEC61960, t he DC resistance can be measured as follows: A DC current step is applied to measure the change in the cell''s voltage.
For a battery test to be valid, it should be charged to 100% before beginning the test. If an issue is encountered the self test will be aborted and the UPS will immediately return on to online operation. If the battery performance indicates a failing battery, the UPS will signal a bad battery via the replace battery LED and/or LCD screen.
Likewise, a strong battery with low charge shares similarities with a pack that exhibits capacity loss. Battery characteristics are also swayed by a recent charge, discharge
Cell testing and the data thereof underpins the fundamental design of a battery pack from the initial sizing through to control system parameterization and final sign-off of the system.
