2.1. Hybrid pulse power characterization As a time domain test, a HPPC test is based on direct current (DC) pulses, where the test profiles are usually composed of a discharge pulse, a relaxation, a charging pulse, and another relaxation, each with a defined pulse current amplitude and duration.
The 'Hybrid Pulse Power Characterization (HPPC) Test' is a test employed in battery performance characterization. It provides data for battery management systems (BMS) to assess cell performance, particularly the maximum deliverable power & state of charge (SOC).

Industry-standard diagnostic methods for rechargeable batteries, such as hybrid pulse power characterization (HPPC) tests for hybrid electric vehicles, provide some indications of state of health (SoH), but lack a physical basis to guide protocol design and identify degradation mechanisms.
4.3. Hybrid systems In a hybrid system, the battery and capacitor each provided a share of the power to the load during the active pulse and then the battery recharged the capacitor during the pulse ‘off’ time. Fig. 7 shows the individual current profiles for the lithium-ion battery, 50 F ultracapacitor, and load in a hybrid system.
However, the HPPC was originally designed for determining the dynamic power capability of the tested battery using a profile that incorporates both discharge and regen pulses, which is quite different from the parameters’ identification, therefore it is meaningful to make the profile fit the parameters’ identification.
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.
