What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12584968B2 for a "Method for monitoring the state of a redox flow battery system." The patent, assigned to LIVA Power Management Systems GmbH, details a process for assessing the health of individual battery modules within a larger system by temporarily isolating and discharging them to measure potential differences.

This patent grant is primarily an intellectual property event and does not impose direct regulatory obligations on companies. However, it signifies a new technological development in battery monitoring that could influence future product designs and industry standards. Companies involved in the manufacturing or deployment of redox flow batteries should be aware of this patented technology, particularly if their monitoring methods may infringe upon the claims outlined in the patent.

Abstract

A method for monitoring the state of a redox flow battery system that includes at least two battery modules connected in series. The method includes the following steps: S1: switching at least one battery module out of the series circuit; S2: discharging at least a partial volume of the electrolyte of the at least one battery module that was switched out of the series circuit in step S1, a potential difference being repeatedly detected, the potential difference being formed between a first potential of the negative electrolyte and a second potential of the positive electrolyte of the at least one battery module that was switched out of the circuit; S3: determining, from the potential difference values detected in step S2, the state of health of the at least one battery module that was switched out of the series circuit in step S1.
