Abstract
A method of determining the state of charge (SOC) of a battery. The method may employ a transformation technique that linearizes a nonlinear model by converging close to a measured value and thereby estimating the state of charge accurately without affecting the computation time and load on the system. The transformation technique employs an adaptive unscented Kalman filter (UKF).
