Abstract
Electrochemical impedance spectroscopy (EIS) may include testing various voltages and currents, storing and sending the data to an electrochemical impedance spectroscopy analyzer (EISA) network, where the data may be compared to historical data to determine a safety threshold that may provide preferred operating use of a device battery, and in response to a battery level exceeding a safety threshold, the battery may be halted.

16-20. (canceled)
A method for managing sharing of electrochemical impedance spectroscopy (EIS) battery testing data, comprising:
- receiving an EIS test waveform for an EIS test on a battery, a response waveform for the EIS test, and performance parameters of the battery from an EIS system;
- storing the EIS test waveform, the response waveform, and the performance parameters in a learned database as associated with the battery, and
- comparing the EIS test waveform, the response waveform, and the performance parameters with historical EIS test waveforms, historical response waveforms, and historical performance parameters associated with a type of battery corresponding to the type of battery for the battery and a poor performance event for the battery to determine EIS testing information for the battery exhibiting the poor performance event.
