Abstract
Electrochemical impedance spectroscopy (EIS) data collected over a period of time for a large number of batteries and different types of batteries, may be collected and analyzed to generate or refine a learned database of EIS waveforms and induction responses to perform in-situ analysis of the battery and suggest optimal time for charging the battery.
Claims18
An electrochemical impedance spectroscopy analyzer (“EISA”) system, comprising:
- an EISA network, comprising:
- a charging module;
- and
- a learned database,
- wherein the charging module is configured to:
- receive 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 electrochemical impedance spectroscopy (“EIS”) system communicatively connected to the EISA network;
- and
- store the EIS test waveform, the response waveform, and the performance parameters in the learned database as associated with the battery,
- wherein the learned database is configured to analyze 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 the battery to determine EIS testing information for the battery that results in the best battery performance.
An electrochemical impedance spectroscopy analyzer (“EISA”) system, comprising:
- an electrochemical impedance spectroscopy (“EIS”) system electrically connectable to a battery;
- and
- a charger communicatively connected to the EIS system and electrically connectable to the battery, and comprising:
- a charger control module;
- and
- a charger database;
- wherein the charger control module is configured to:
- identify the battery;
