  • Electrochemical impedance spectroscopy in battery management systems
    Patent number: 10386422
    Abstract: The invention pertains to a method of determining the State of Health (SoH) and/or State of Charge (SoC) of a rechargeable battery during use of said battery, the method comprising the steps of: generating a first excitation signal within a first selected frequency range, generating a second excitation signal within a second selected frequency range, applying said first and second excitation signals on said rechargeable battery, measuring the response signal for each of said two excitation signals, and then calculate the Electrochemical Impedance (El) as the ratio between the excitation signals and respective response signals, and then determine the SoH and/or SoC of the rechargeable battery by comparing the calculated El to a circuit model for the battery and/or determining the SoH and/or SoC of the rechargeable battery by directly evaluating characteristics of the El. The invention also pertains to a battery management system configured for executing the steps of the method according to the invention.
