Application: Battery anomaly detection device and battery anomaly detection method (Patent ID: US20240110992A1)
The patent filed by Winbond Electronics Corp describes a battery anomaly detection device that includes an AC impedance measurer to measure the AC impedance of a battery cell, and an anomaly determiner to determine if the AC impedance falls within a reference range. If the AC impedance is outside the reference range, the device identifies the battery cell as anomalous. The device can measure the AC impedance of multiple battery cells connected to each other, calculate the reference range based on the measured AC impedances, and exclude extreme values to determine the average value for setting the reference range.
Additionally, the device can store previously measured AC impedance values to determine the reference range, set the reference range based on the current state of the battery cell, communicate with a server device to obtain the reference range, measure the AC impedance when the battery cell is in thermal equilibrium or in a predetermined state, and determine anomalies based on the AC impedance falling outside the reference range. The patent also covers a method for battery anomaly detection that involves measuring the AC impedance of a battery cell, checking if it falls within a reference range, and identifying the cell as anomalous if the impedance is outside the reference range.
