Flowbat group

A typical vanadium redox flow battery cell is symmetric and consists of two equal half-cells. Each half cell contains: Current collector (provides the electrons to the circuit), Bipolar plate (maintains the electron transfer between electrodes from different cells or between an electrode and a current collector), Electrode (the redox reaction occurs on its surface), Flowframe (provides the fluid flow in the cell). One of the research purposes is the optimization of the whole stack design and modification of each component, to provide the best performance and lifespan of the battery.

Battery Management System (BMS) is a core of the battery that controls and monitors its main parameters preventing battery from emergence cases, improving its performance and lifespan. Our battery management platform is developed under high industrial standards and has a model-based-design that allows users to configure the BMS according to the application’s requirements and the battery’s capabilities. The BMS is comprised of hardware and software components, integrated with WEB-based SCADA monitoring system that shows the main parameters of the battery on one screen and provides alerts for emergency cases. Thus, you can easily monitor instant battery state, voltage, current and temperature with the browser whenever you are.

The simulation tool for modeling of RFB systems with different sizes (lab-scale – industrial-scale) under different operating conditions (loading current, flow rates, temperatures, etc.). The core of our simulator is a zero-dimensional dynamical model developed by our group that combines high accuracy with fast simulation time. The model was validated with a wide set of experimental data, demonstrating good agreement with experiments.
