배터리의 충전상태를 추정하는 방법은 충전상태 초기값 및 칼만 오차공분산 초기값을 설정하는 단계, 상기 배터리의 G 파라미터 추정값, 전류 현재값, 및 전압 현재값을 수신하는 단계, 확장 칼만 필터에 상기 G 파라미터 추정값, 상기 전류 현재값, 및 상기 전압 현재값을 입력하여, 상기 배터리의 충전상태 현재값과 상기 칼만 오차공분산 현재값을 갱신하는 단계, 및 상기 충전상태 현재값을 출력하는 단계를 포함한다.

    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.
