Such an in-depth investigation is of solid significance for vanadium flow batteries to optimize their flow rate. In addition, a cost-effective method is successfully provided by the proposed dynamic model, thereby minimizing repeated field tests, extended testing periods, and the consumption of considerable electrical energy.
The charging process of a vanadium flow battery is determined by the transport characteristics of the battery electrolyte, which will affect the performance of the battery and the loss and efficiency of the circulating pump.
This demonstrates the advantage that the flow batteries employing vanadium chemistry have a very long cycle life. Furthermore, electrochemical impedance spectroscopy analysis was conducted on two of the battery stacks. Some degradation was observed in one of the stacks reflected by the increased charge transfer resistance.
It is worth noting that no leakages have been observed since commissioned. The system shows stable performance and very little capacity loss over the past 12 years, which proves the stability of the vanadium electrolyte and that the vanadium flow battery can have a very long cycle life.
The paper presents a control method of the electrolyte flow factor in kW-class Vanadium Redox Flow Batteries that minimizes transport losses without affecting the battery's electrical performance. This method uses experimental data acquired on a 9 kW/27 kWh test facility at varying operating conditions.
