6 FAQs about [Battery pulse power test method]

What is battery hybrid pulse power characterization (HPPC)?

The battery hybrid pulse power characterization (HPPC) test is performed in controlled environmental chambers. A typical HPPC data is a set of discharge-charge pulses, applied to a battery at different state of charge (SOC) and at a given temperature . The magnitude of the pulse depends upon the cell capacity and the test temperature.

How does HPPC test a battery?

The HPPC test involves applying a current pulse to the battery while recording the voltage response. The current pulse includes a discharge pulse followed by a relaxation period & then a charge pulse. This sequence is repeated at various SOC levels to comprehensively characterize the battery's performance over its entire operating range.

How does a battery test work?

On the one hand, this allows the battery to reach ambient temperature, and on the other hand, it stabilizes its terminal voltage. All tests were automated, using the BaSyTec tester to ensure a reproducible timing sequence of the tests and to reduce the effect of calendar aging on the results.

Can voltage pulses be used to diagnose battery degradation behavior?

The ability to gain deeper insights into the underlying physical mechanisms makes voltage pulses a superior choice in diagnostics. The goal of this work has been to enhance the physical under-standing of HPPC protocols as a means to diagnose battery degradation behavior.

How do you test a battery?

More sophisticated testing procedures are found outlined in the Federal Consortium for Advanced Batteries (FCAB) test manual listed in the Reference section of this report. The baseline RPT is performed first. Cells are then equilibrated to 25°C for 3 hours followed by a standard CC-CV charge to 100% SOC.

What is battery performance testing?

The purpose of this manual is to document a series of battery performance testing procedures to standardize data collection and to promote data sharing and utilization across the U.S Navy and Marine Corps. Standardization of battery data collection is required to accurately assess and compare emerging battery technologies against one another.
