Abstract

Techniques to diagnose internal short circuits (ISCs) of a lithium-ion battery (LIB) are disclosed. The short circuit resistance data can help to detect the ISCs of a LIB as fast as possible. For the proposed detection techniques, a resistor-based circuit and an inductor-based circuit are disclosed for single-cell LIBs as well as for LIBs having multiple cells. Two topologies of the resistor-based circuits are disclosed to detect the ISCs of multi-cell LIBs.
