MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202617062189 A) filed by Murata Manufacturing Co. , Ltd. on May 15, 2026, for Secondary Battery Diagnosis System And Secondary Battery Diagnosis Method.
Inventor includes Masuda Yasuyuki.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: A secondary battery diagnosis system according to an embodiment of the present technology selects, on the basis of normal OCV data pertaining to a first secondary battery in a normal state, specific OCV data with which the regular OCV data can be approximated from among a plurality of virtual OCV data obtained from a plurality of positive electrode OCP data and a plurality of negative electrode OCP data. The secondary battery diagnosis system furthermore estimates, on the basis of the positive electrode OCP data and the negative electrode OCP data from which the specific OCV data is obtained, a plurality of deterioration OCP data for when the first secondary battery deteriorates under various conditions, and determines, on the basis of the plurality of deterioration OCP data obtained through the estimation, an OCV measurement section for measuring the OCV of a second secondary battery.
