Abstract

The embodiment of the present application discloses an abnormality detection method, equipment, and storage medium, wherein the method includes: when the electronic equipment is in the charging state, determining the first electrical parameter between the two ends of the connection circuit in the charging module of the electronic equipment value; wherein, the connection circuit is used to establish an electrical connection between the output terminal of the charging interface in the charging module and the input terminal of the rechargeable battery in the charging module; determine the connection from the input terminal of the charging interface to the The second electrical parameter value between the input terminals of the rechargeable battery; according to the relationship between the first electrical parameter value and the preset first threshold value, the relationship between the second electrical parameter value and the preset second threshold value The abnormality detection is performed on the electrical parameter value of the charging interface.

Description

technical field [0001] The embodiments of the present application relate to electronic technologies, and relate to, but are not limited to, anomaly detection methods, devices, and storage media. Background technique [0002] With the development of charging technology, the charging speed of the terminal has been greatly improved. However, with it comes the question of how to ensure the safety of charging. A common technical means is that when the power adapter is connected to the power supply to charge the terminal, the power adapter obtains the path impedance of the charging module in the terminal, and adjusts the charging current according to the path impedance. For example, when the path impedance is greater than the preset threshold, it is determined that the path impedance is abnormal, and at this time, the power adapter reduces the charging current to ensure charging safety. However, in this way, it is impossible to determine which position in the charging module is ...
