This project focuses on the estimation of the state of charge (SoC) and state of health (SoH) in vanadium redox flow batteries (VRFB), which are critical for understanding the performance and reliability of these energy storage systems (ESS). The project aims to develop a comprehensive model that accurately reflects the behavior of VRFBs under various operating conditions. The project begins with an introduction to the significance of VRFBs in the context of climate change and the need for efficient energy storage solutions. It then explores the historical evolution of batteries, the chemistry behind VRFBs, and the system’s components, including the role of the membrane and the impact of influential processes like ion crossover. The core of the project involves the development and simulation of electrochemical and voltage models using MATLAB/Simulink. These models consider the dynamics of vanadium species concentrations and the factors influencing the battery’s voltage output. The project also explores the influence of different modeling assumptions on the accuracy of the future SoC and SoH estimations. Additionally, the project includes an economic analysis of the project, and an environmental analysis of VRFBs, highlighting their potential to mitigate climate change and improve energy efficiency. The findings from this research contribute to the advancement of VRFB technology and provide insights into the design and control strategies necessary for optimizing the performance and longevity of these batteries
