ALEXANDRIA, Va., Dec. 31 -- United States Patent no. 12,512,499, issued on Dec. 30, was assigned to COUGAR CREEK TECHNOLOGIES LLC (Kirkland, Wash.).

"Methods and systems for determining average oxidation state of redox flow battery systems" was invented by Kui Wei (Bellevue, Wash.) and Liyu Li (Bellevue, Wash.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A method for determining an average oxidation state (AOS) of a redox flow battery system includes measuring a charge capacity for a low potential charging period starting from a discharged state of the redox flow battery system to a turning point of a charge voltage; and determining the AOS using the measured charge capacity and volumes of anolyte and cath...
