Abstract

A process for determining an impedance of a battery cell may comprise delivering an excitation current to the battery cell; performing, via an analog-to-digital converter (ADC), one or more first measurements associated with the battery cell in the presence of the excitation current, wherein the one or more first measurements comprise one or more current measurements; performing, via the ADC, one or more second measurements associated with the battery cell in the presence of the excitation current, wherein the one or more second measurements comprise one or more voltage measurements; and determining the impedance of the battery cell based on the one or more first measurements and the one or more second measurements.
