Firstly, a state space model is constructed based on the Thevenin circuit model of lithium batteries. On this basis, a state prediction set is constructed and combined with the time-delayed sensor measurement data. Based on the Minkowski property of zonotopes, an estimation set is constructed. By applying the F-radius contraction model, the filtering coefficient is optimized to obtain the optimal estimation of the SoC. Experimental verification on the lithium battery charge and discharge experimental platform shows that the proposed algorithm has higher accuracy and significantly reduced conservativeness compared with the conventional ZKF algorithm.
