ALEXANDRIA, Va., July 16 -- United States Patent no. 12,669,550, issued on June 30, was assigned to Renesas Electronics America Inc. (Milpitas, Calif.).

"Systems and methods for battery reactive impedance measurements" was invented by Anthony John Allen (Los Gatos, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Systems and methods for battery reactive impedance measurement is generally described. The method can include measuring a voltage of a battery cell. The method can further include measuring a current flowing through the battery cell. The method can further include determining a time offset based on the voltage and the current. The time offset can cause the voltage and current to be in-phase. Th...
