As the battery is a non-linear system, a robust dissipative-based Proportional Integral (PI) observer is proposed in this work to estimate the SoC. As special cases based on energy-related concerns, the theory of the dissipative concept incorporates H∞, passivity, and L2 performances. In particular, developing Dissipative PI Observer for the SoC system with disturbances, uncertainty and non-linearity are the major novelties in this study. The suggested system's findings are compared to the results of the Equivalent circuit model method and Coulomb-Counting method. MATLAB/SIMULINK is used to simulate the proposed system. Moreover, using Lyapunov stability theory, a novel set of adequate necessities in terms of LMI is erected to secure the conservative outcome.
