  • Method for estimating state of health of a battery
    Patent number: 11821959
    Abstract: A method for estimating state of health (SOH) of an electric battery includes starting a charging of an electric battery with a charge current, measuring a voltage of the electric battery during the charging, determining a first point in time at which a minimum slope of the voltage curve during the charging occurs, determining a second point in time when the measured voltage of the electric battery equals a maximum charging voltage, determining a SOH-interval between the first point in time and the second point in time, estimating the state of health for the electric battery based on the SOH-interval. The advantage of the method is that an estimated value for the state of health of an electric battery is obtained in an easy and reliable way.
