MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202547092603 A) filed by Lg Energy Solution, Ltd. on September 26, 2025, for Battery Diagnosis Apparatus And Battery Diagnosis Method.
Inventors include Yoon, Seo-Young; Choi, Soon-Hyung; and Kim, Young-Deok.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: Provided are a battery diagnosis apparatus and a battery diagnosis method. The battery diagnosis apparatus according to the present invention comprises: a data acquisition unit for obtaining a first target full cell profile indicating a correspondence relationship between a capacity factor and a voltage of a target cell while a first electrical stimulus is applied to the target cell; and a control circuit that generates an estimated full cell profile on the basis of the first target full cell profile and an overpotential profile. The control circuit determines a first performance factor group as a primary estimation result for the charging and discharging performance of the target cell by applying a cell diagnosis logic to the estimated full cell profile. The control circuit determines a second performance factor group as a secondary estimation result for the charging and discharging performance of the target cell by applying a factor correction model to the first performance factor group. The second performance factor group includes an estimation result of a negative electrode loading amount of the target cell.
