Vanadium redox flow batteries diagnostics adapted for telecommunication application

One of the main factors limiting the development of modern telecommunication devices and systems is finding reliable and efficient energy storage technologies. The Vanadium Redox Flow Battery (VRB) is an emerging candidate that has a high potential to be deployed for such an application. However, the VRB needs a robust control and monitoring system to predict their state of health and to foresee any failures. In this work, we present a nondestructive testing procedure for a VRB. The proposed testing procedure is based on the analysis of equivalent electrical circuit parameters identified by impedance or transient characteristics. Since the suggested approach requires only a small volume of data for transmission, it allows organizing the diagnostic system of energy storages for stationary telecommunication objects.
