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.
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.
