MONITORING ELECTROLYTE CONCENTRATIONS IN REDOX FLOW BATTERY SYSTEMS

Title:

MONITORING ELECTROLYTE CONCENTRATIONS IN REDOX FLOW BATTERY SYSTEMS

Document Type and Number:

WIPO Patent Application WO/2012/135473

Kind Code:

A3

Abstract:

Methods, systems and structures for monitoring, managing electrolyte concentrations in redox flow batteries are provided by introducing a first quantity of a liquid electrolyte into a first chamber of a test cell and introducing a second quantity of the liquid electrolyte into a second chamber of the test cell. The method further provides for measuring a voltage of the test cell, measuring an elapsed time from the test cell reaching a first voltage until the test cell reaches a second voltage; and determining a degree of imbalance of the liquid electrolyte based on the elapsed time.
