Abstract
Various embodiments of the present technology may provide methods and apparatus for a battery. The apparatus may determine a first current according to a first technique and a second current according to a second technique. The apparatus may use a Kalman filter to compute the state of charge of the battery, wherein the Kalman filter uses one of the first current and the second current based on a comparison of the second current to a threshold current.
