| Abstract: | Accurate state of charge(SOC) estimation for battery is very difficult for showing highly nonlinear on battery for electric vehicle.Main factors affecting SOC were analyzed.Strategy of estimating state of charge based on combinatorial algorithm of Kalman filter and Ampere-hour method was presented.State space model of a lithium battery derived from second-order model was proposed,which was combined with structure characteristic of lithium battery.The feasibility and accuracy of the model was verified by usi... |
