Abstract: Provided is a device including an acquisition unit configured to obtain a time taken for a voltage level of a battery in a charge mode to change for each of a plurality of voltage sections, and a prediction unit configured to predict a state of health (SOH) of the battery based on ratio information determined by comparing the time obtained for each of the plurality of voltage sections with a reference time for each of the plurality of voltage sections. When the time taken for some voltage sections of the plurality of voltage sections is obtained by the acquisition unit, the prediction unit corrects the predicted SOH of the battery based on the time taken for the voltage level of the battery in a discharge mode to change.

Abstract: A module system of a redox flow battery is disclosed. The system includes a first redox flow battery module, through which first and second electrolytic solutions circulate, a second redox flow battery module, through which first and second electrolytic solutions circulate, first and second storage tanks storing the first electrolytic solutions of the first and second redox flow battery modules, a first main pipe connecting the first redox flow battery module fluidically to the first storage tank, and a first transfer pipe and a first equilibrium pipe which are configured to allow for fluid communication between the first electrolytic solutions of the first and second redox flow battery module. The first main pipe has a diameter greater than that of the first transfer pipe.
