Abstract
Electrochemical impedance spectroscopy (EIS) may be used to measure the internal components of a battery or interfaces between connections inside a battery in order to determine a state of one or more subcomponents of the battery. In various embodiments, EIS testing of the battery may be conducted using various test waveforms, such as test waveforms with different voltages, currents, and/or frequencies, to identify and/or predict battery subcomponent and/or interface failures. In various embodiments, EIS testing of the battery may be used to determine when battery conditions are suitable for charging.
