Continuous and peak current

The current a cell can supply indefinitely without exceeding its temperature limit, and the higher current it can supply for a stated few seconds. Peak ratings are only valid for the duration and starting temperature given.

Cycle life

The number of full charge–discharge cycles a cell completes before its capacity falls to a stated fraction, usually 80 %, of its initial value under defined conditions. LFP cells reach several thousand cycles; high-energy NMC fewer.

Depth of discharge

How much of a cell’s capacity is used in a cycle. Deep cycles cause more mechanical stress in the active materials than shallow ones.

Pulse test

Applying a current step of defined size and duration and recording the voltage response. The instant voltage step gives the ohmic resistance, the following curve the slower polarization; HPPC is a standardised sequence of such pulses across state of charge.
