Abstract

The paper aims at characterizing the electrochemical and thermal parameters of a 15 kW/320 kWh
vanadium redox flow battery (VRB) installed in the SYSLAB test facility of the DTU Risø Campus and
experimentally validating the proposed dynamic model realized in Matlab-Simulink. The adopted testing
procedure consists of analyzing the voltage and current values during a power reference step-response
and evaluating the relevant electrochemical parameters such as the internal resistance. The results of
different tests are presented and used to define the electrical characteristics and the overall efficiency of
the battery system. The test procedure has general validity and could also be used for other storage
technologies. The storage model proposed and described is suitable for electrical studies and can represent a general model in terms of validity. Finally, the model simulation outputs are compared with experimental
measurements during a dischargeecharge sequence.
