摘要： A system and method for measuring the state of charge (SOC), molarity and concentrations of active species and oxidation state of a flow battery, such as a Vanadium Redox Flow Battery (VRFB). A reference electrolyte is circulated through a reference cell in conjunction with one or both charged electrolytes (in respective conduits). The electric potential of charged electrolyte relative to a reference electrolyte is measured. This measurement is directly convertible to SOC. An equation allowing for the calculation of the molarity, concentration of vanadium ions on both anolyte and catholyte sides of the flow battery and oxidation state is also taught. A flow battery may be controlled in response to such a determination, for example to manage oxidation state, or to charge or discharge a battery.
