Abstract

Lithium-sulphur batteries appear to be an exciting technology for energy storage. This technology could be used in aviation, aerospace or in heavy electric vehicles, or even for mobile applications. This article deals with the implementation of a modified Li-S battery charging and discharging model, specifically in the MSMD module, which does not have this model by default. The behavior of the new model was tested experimentally on a real Li-S battery and the results were compared with simulations, which gave very good and consistent results. Compared to commonly used equivalent circuit models, MSMD is able to study macroscopic effects such as electric potential distribution or temperature distribution in the battery, while the simulation remains simple, fast and accurate.
