  • Patent number: 11196104
    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 battery event as a user action recommendation may provide preferred operating use of a device battery in response correlation of EIS test results and comparison for similarities of EIS test results. Historical EIS test data may be stored in an EISA network with a server configured to receive EIS test results from battery-operated devices, correlate received EIS test data to historical EIS test data, and provide recommendations on battery use and/or maintenance to the battery-operated device based on the correlation results. Analyzing EIS test data and sending recommendations on battery use and/or maintenance service may be provided on a subscription basis.
