Vanadium redox flow batteries (VRFBs) are considered as promising electrochemical energy storage systems due to their efficiency, flexibility and scalability to meet our needs in renewable energy applications. Unfortunately, the low electrochemical performance of the available carbon-based electrodes hinders their commercial viability.
A thermal hydraulic model is developed for vanadium flow battery. The pump power is sensitive to hydraulic design and flow rates. Thermal hydraulic model is benchmarked with experimental data. Sensitivity of efficiencies on the temperature, current, and flow rate is studied. Optimal flow rates to reach highest battery efficiency are obtained.
A dynamic model of the VRFB based on the mass transport equation coupled with electrochemical kinetics and a vanadium ionic diffusion is adopted to determine the optimal flow rate of the vanadium electrolyte by solving an on-line dynamic optimization problem, taking into account the battery capacity degradation due to electrolyte imbalance.
Moreover, an all-vanadium redox flow battery already utilizes a fluid circulation circuit, making the thermal management easier. In the case of MAE, the possibilities to improve the system are broader than for the conventional electrolyte because of the electrolyte's higher thermal stability and vanadium solubility limit.
The results show that the on-line optimization of the vanadium flow rate incorporated with the EKF estimator can enhance the system efficiency (7.4% increase in state of charge) when the VRFB is operated under the intermittent current density.
