AbstractThe multi-stack module containing several stacks is commonly used to form a flow battery system for large-scale energy storage applications. The performance and safety of such modules can be highly affected by the module thermal behavior. To fully investigate the thermal behavior of all-vanadium flow battery module, an in-depth analysis is for the first time conducted for an eight-stack 250 kW module. To begin with, both the experimental and simulated results confirm the existence of a fast temperature rising in operation. After that, simulation results further demonstrate that the module temperature variations during charge-discharge cycling can be divided into three phases of fast rising, slowly rising and keeping. In addition, the temperatures of the stacks in the module are very close, with a certain extent higher than those of the tanks. Besides, the temperature rising can be notably moderated by lowering the applied current, extending the storage time, reducing the surrounding air temperature, enlarging the tank surface area and rising up the flow rate. The in-depth study not only provides a cost-effective method to predict and control the temperature variations of multi-stack modules, but also offers a mechanistic insight into the module thermal behavior.
