MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202527089720 A) filed by Eliiy Power Co. Ltd., Tokyo, on Sept. 19, for 'secondary-battery-unit charging state estimation device, secondary-battery-unit charging state estimation method, and secondary-battery-unit charging state estimation program.'
Inventor(s) include Miyazaki, Takahiro.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "Provided are a secondary-battery-unit charging state estimation device, a secondary-battery-unit charging state estimation method, and a secondary-battery-unit charging state estimation program with which it is possible to estimate, in real-time with good followability, the state of charge (SOC) of a secondary battery on the basis of parameters at the time of measurements. The present invention provides a secondary-battery-unit charging state estimation device that estimates, by employing formula 1 or 2, the state of charge (SOC) or the state of power (SOP) of a secondary battery unit that has at least one battery cell, wherein the secondary-battery-unit charging state estimation device is equipped with a corrected full-charge-capacity calculation means for calculating a corrected full charge capacity (FCCadj) of the secondary battery unit, and the corrected full-charge-capacity calculation means calculates a corrected full charge capacity (FCCadj) by employing a Weibull function that employs, as the variables, indices that are based on physical quantities at the time of measurements, obtained from the secondary battery unit."
The patent application was internationally filed on Feb. 22, 2024, under International application No.PCT/JP2024/006454.
