Abstract

The embodiment of the invention discloses an anomaly detection method and device and a storage medium. The method comprises steps of determining a first electrical parameter value between two ends ofa connection circuit in a charging module of electronic equipment when the electronic equipment is in a charging state; wherein the connecting circuit is used for establishing electric connection between the output end of a charging interface in the charging module and the input end of a rechargeable battery in the charging module; determining a second electrical parameter value between the inputend of the charging interface and the input end of the rechargeable battery; and according to the relationship between the first electrical parameter value and a preset first threshold value and the relationship between the second electrical parameter value and a preset second threshold value, carrying out anomaly detection on the electrical parameter value of the charging interface.

Description

technical field [0001] The embodiments of the present application relate to electronic technology, and involve 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 terminals has been greatly improved. However, what follows is the question of how to ensure charging safety. A commonly used technical means is that when the power adapter is connected to a power source to charge the terminal, the power adapter obtains the channel impedance of the charging module in the terminal, and adjusts the charging current according to the channel impedance. For example, when the channel impedance is greater than a preset threshold, it is determined that the channel 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 ...
