Evaluating Battery Deterioration
Measuring lithium-ion batteries
The instrument measures internal resistance and voltage of
batteries using AC having a frequency of 1 kHz. The internal
resistance of lithium-ion batteries can also be measured; however,
that of a packed battery will include the protective resistance, which
is installed in packed batteries. Besides, the instrument may not be
able to diagnose and evaluate the deterioration of such batteries
because changes in the internal resistance of lithium-ion batteries
due to deterioration may be smaller than lead-acid batteries.
