Abstract
A system is disclosed for determining complex impedance characteristics of one or more battery cells based on the charge signal applied, or to be applied, to the battery cell. Implementations may include measuring the impedance of a battery cell to, in some instances, determine a frequency component or harmonic that defines, at least a portion, of a waveform shape for charging the battery cell. In one implementation, the impedance at the battery cell may be measured or estimated from a discrete charge period being applied to the battery cell or from multiple discrete charge periods applied to the battery cell. The measured differences between the amplitude and time components of the voltage and current waveforms may be used to determine or estimate the magnitude, phase shift, real, and/or imaginary values of the impedance at the battery cell.
