Abstract
A method of estimating a state-of-charge (SOC) of a battery includes: setting an initial SOC value and an initial Kalman error covariance value; receiving an estimated G parameter value, a current current value, and a current voltage value of the battery; updating a current SOC value and a current Kalman error covariance value of the battery by inputting the estimated G parameter value, the current current value, and the current voltage value to an extended Kalman filter; and outputting the current SOC value.
