Theory 123/Battery charge cycle/Termination phase
Termination Is a Voltage Cutoff
The claim
A charge ends when the ratio of cell voltage to cutoff voltage reaches one, so the same capacity corresponds to different states depending on rate.
01Mechanism
Polarisation raises the terminal voltage; the ratio sets the stop.
02Prediction
Cutoff state should vary with rate.
03Refutation
Cutoff independent of rate would remove polarisation.
