An Internal Resistance Consistency Detection Approach for Lithium
Lithium-ion batteries (LIBs) are widely used in electric vehicles (EVs). The internal resistance consistency is essential to the performance and safety of LIB packs. To detect the consistency of the LIB cell efficiently, an approach using the unbalanced current is proposed. First, a simple bridging circuit model with four LIB cells is built based on the first-order Thevenin equivalent
