Abstract

The present disclosure describes a technology for detecting various errors in a battery that occur during a process of activating a battery by repeatedly charging, discharging, and stabilizing. The technology classifies stabilization sections using information measured from the battery and outputs them along with battery data. When a battery error is detected, it outputs a battery error alarm at the corresponding location. When the battery error alarm is selected, it outputs a recipe for the corresponding stabilization section.

Description

Battery Error Detection Apparatus The present invention relates to a technology for detecting various errors in a battery while repeating charging, discharging, and stabilization to activate the battery. With the advancement of electronic devices and the increasing adoption of electric vehicles, the production and use of batteries are on the rise. After production, batteries must undergo a process called formation before they can be used as cells that store electrical energy. During the formation process, batteries undergo repeated charging and discharging cycles. Meanwhile, various errors can occur during the battery activation process, and these errors lead to battery defects. Since the continued use of defective batteries can result in serious accidents, it is necessary to accurately detect and analyze the errors that occur during the activation process. Conventional technology outputs data generated during the battery activation process in the form of a two-dimensional graph. Conventional technology visualizes data using graphs, lines, etc., to enable intuitive and rapid understanding of complex numerical values or information, and allows for the expression of voltage, current, capacity, and temperature. However, conventional technology has the problem that accurate error detection is difficult due to the complexity of data patterns, lack of objective criteria, lack of real-time response, and lack of automated analysis functions. Furthermore, the ability to interpret visualized data varies depending on the user; since conventional technology relies on the user's analytical skills, there is a problem in that deviations are inevitable in grasping the precise meaning of the data and detecting battery abnormalities. Consequently, conventional technology has a problem of inconsistency in error detection (anomaly detection) because there is no automated algorithm for error detection, and the level of error detection varies depending on each user's experience or analytical ability, even with the same data. Furthermore, conventional technology outputs complex data through simple visualization, which inevitably provides non-intuitive information; consequently, important patterns in the data may be missed, or the accuracy of identifying anomalies may be reduced. The matters described in the background technology above are intended to aid in understanding the background of the invention and may include matters that are not disclosed prior art.
