With increasing commercial applications of vanadium flow batteries (VFB), containerised VFB systems are gaining attention as they can be mass produced and easily transported and configured for different energy storage applications. However, there are limited studies on the thermodynamic modelling of containerised vanadium redox flow battery systems, and thermal control designs. In this paper, a dynamic thermal model is developed for containerised VFB systems, based on which thermal design options are evaluated using simulation studies.
