Abstract

This brief is an attempt toward the development of a simpler model of Li-ion batteries to be used in model-based battery monitoring and diagnostics. We present a Takagi-Sugeno fuzzy model that can appropriately cope with the nonlinear dynamics of the battery through its inherent multiple-model structure. The proposed model can easily be expanded to any desired range of operation and is also appropriate for the implementation of control strategies. Further, an analytical observer design for the battery diagnostic is also introduced. The effectiveness of the proposed model is verified through a number of simulation studies.
