Battery knowledge · Capacity, energy, power and ratings
Datasheet
The manufacturer’s specification sheet for a cell: nominal capacity, nominal voltage, voltage window, continuous and peak currents, operating temperatures, dimensions, mass and cycle life, each tied to the test conditions it was measured under.
Example
Capacity, energy, power and ratings: an example situation
5 Ah at 3.6 V gives 18 Wh nominally. Integrated measured terminal power may give a different result.
Read Datasheet alongside Cycle life in this context. 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.
Use in Lemonergy
Separate nameplate ratings from test results.
This is a reference concept. No executable Lemonergy block has been verified for this term.
