Treatment of Electric Short-Circuit in Electrochemical-Thermal Coupled Battery Simulations

Lithium-ion batteries have been widely used in electric vehicles (EVs). Their performance, life and safety are of great engineering importance. Using simulation tools, electric performance and thermal behavior of a battery can be computed to provide useful information in battery design. Internal short-circuit is one of the important failure modes in battery’s safety study. Internal short treatment is added to the framework of the multi-scale multi-dimensional (MSMD) battery modeling methodology. The method is demonstrated in the present paper by simulating a single lithium-ion battery cell.
