Analysis of Pump Loss on the Performance and Effect of all Vanadium Redox Flow Battery

Abstract: A vanadium redox flow batteries system was modelling. Through theoretical analysis and research based on the all vanadium redox flow batteries system under different pipe diameter and velocity of pump loss, and it is concluded that the pump depletion of the law. Using the Fluent software simulation half cell electrolyte distribution under different flow rate,different charging current and velocity affect the performance of all vanadium redox flow batteries. Results show that according to the loss of vanadium battery structure optimization control pump and the electrolyte flow rate, to improve the efficiency of vanadium battery energy storage system and the battery system stability is very important. In the large scale energy storage technology, the pump damage and the influence of flow rate is more apparent.
