A brief of Impedance-based Battery Management System

Impedance is an important feature of linear two-port networks. As a system with strong nonlinearity and time-variation, the impedance of the battery needs to be obtained under conditions satisfying causality, stability, and linearity, otherwise, the obtained impedance is difficult to resolve or loses physical significance. Therefore, it is common to apply unbiased weak disturbances (such …
